- The impact of travel distance to treatment centre on oral tongue squamous cell carcinoma survival and recurrenceby J.R. Daniell, X. Dolja-Gore, L. McDowell, C. Udovicich, D. Rowe, T.A. Iseli, T. Wong, M.J.R. Magarey, D. Wiesenfeld on 20/09/2021 at 12:00 am
There have been no prior studies examining the effect of distance to the treatment centre on oral squamous cell carcinoma outcomes in Australia. The purpose of this study was to analyse the impact of travel distance on oral tongue squamous cell carcinoma (OTSCC) outcomes. This was a retrospective analysis of 243 patients who received surgical treatment ± adjuvant therapy between 2007 and 2016. The overall survival (OS), disease-specific survival (DSS), and freedom from loco-regional failure (FFLRF) survival analyses were conducted using Kaplan–Meier curves and a multivariate Cox proportional hazards model.
- Correlation of preference- and profile-based quality of life of Japanese oral cancer patients during the perioperative period measured using EQ-5D-5L and FACT-H&Nby T. Aoki, Y. Ota, K. Izawa, Y. Osawa, S. Seta, B. Tsuda on 20/09/2021 at 12:00 am
The EuroQol 5-dimension 5-level (EQ-5D-5L) instrument is among the most used preference-based quality of life (QOL) measures for cost–utility analysis. Each dimension is evaluated on five levels. The aim of this study was to clarify whether the EQ-5D-5L, which consists of only five items, correlates with profile-based QOL measures in Japanese oral cancer patients during the perioperative period. One hundred participants with oral cancer undergoing radical therapy completed QOL assessments before treatment, at treatment completion, and 1 and 3 months after treatment using the EQ-5D-5L and Functional Assessment of Cancer Therapy – Head & Neck instrument (FACT-H&N, Japanese version).
- Management of sinus graft infection—a systematic reviewby M. Schlund, J. Meeus, C. Politis, J. Ferri on 20/09/2021 at 12:00 am
Sinus graft infections are rare but serious complications, as they are associated with significant morbidity and sinus graft loss. The aim of this study was to systematically review the management of sinus graft infection in order to define which protocols should be implemented. The terms searched in each database were “sinus graft infection management”, “maxillary sinus lift infection”, “maxillary sinus graft infection”, “maxillary sinus elevation infection”, and “maxillary sinus augmentation infection”.
- Performance of deep convolutional neural network for classification and detection of oral potentially malignant disorders in photographic imagesby K. Warin, W. Limprasert, S. Suebnukarn, S. Jinaporntham, P. Jantana on 18/09/2021 at 12:00 am
Oral potentially malignant disorders (OPMDs) are a group of conditions that can transform into oral cancer. The purpose of this study was to evaluate convolutional neural network (CNN) algorithms to classify and detect OPMDs in oral photographs. In this study, 600 oral photograph images were collected retrospectively and grouped into 300 images of OPMDs and 300 images of normal oral mucosa. CNN-based classification models were created using DenseNet-121 and ResNet-50. The detection models were created using Faster R-CNN and YOLOv4.
- Midline versus paramedian mandibulotomy for tongue cancer surgery: analysis of complicationsby T.-H. Chiu, F. Marchi, S.-F. Huang, C.-J. Kang, C.-T. Liao, S.-Y. Hung, D.C.-F. Cheong, C.-K. Tsao on 14/09/2021 at 12:00 am
Midline and paramedian mandibulotomies both have distinct anatomical and surgical strengths. A retrospective study was performed at Chang Gung Memorial Hospital, Linkou Branch between 2014 and 2019 to investigate how the osteotomy site (midline (n = 221) or paramedian (n = 44)) and type (straight, notched, or stair-stepped) affect postoperative and post-radiotherapy complications in patients undergoing wide excision of tongue cancer with flap reconstruction. Midline mandibulotomies were predominantly of the straight osteotomy type, while paramedian mandibulotomies were mostly notched type (P < 0.001).
- Lymphoepithelial carcinoma in the sublingual glandby L.-C. Mong, K.-F. Liu, Y.-H. Lin, C.-Y. Wu on 14/09/2021 at 12:00 am
Lymphoepithelial carcinoma is rare in the salivary glands, with an incidence of 0.4%. The most commonly affected site is the parotid gland, followed by the submandibular gland. Lymphoepithelial carcinoma in the sublingual gland has been reported only four times in the existing English-language literature. Such tumours are characterized by the presence of a poorly differentiated carcinoma that is surrounded and infiltrated by lymphocytes, and they are strongly associated with Epstein–Barr virus infection, patient ethnicity, and prominent radiosensitivity.
- Clinical performance of tooth root blocks for alveolar ridge reconstructionby S. Bazal-Bonelli, L. Sánchez-Labrador, J. Cortés-Bretón Brinkmann, F. Pérez-González, C. Méniz-García, J.M. Martínez-González, J. López-Quiles on 08/09/2021 at 12:00 am
This systematic literature review set out to investigate the clinical outcomes of autogenous tooth root blocks used for ridge augmentation: survival rates, block resorption, implant survival, post-surgical complications, and histology findings. This review followed PRISMA guidelines. An automated search was made in four databases, supplemented by a manual search for relevant articles published before December 2020. The quality of evidence provided was assessed with the Newcastle–Ottawa Quality Assessment Scale and the Joanna Briggs Institute Critical Appraisal tool.
- Power chains as an alternative to steel-wire ligatures in temporary maxillomandibular fixation: a pilot studyby L.J. van Ewijk, T.C.T. van Riet, I.G.H. van der Tol, J.P.T.F. Ho, A.G. Becking on 08/09/2021 at 12:00 am
The aim of this study was to compare two techniques for temporary intraoperative maxillomandibular fixation (TIO-MMF) during orthognathic surgery: steel-wire ligatures versus power chains. Patients undergoing orthognathic surgery between October 2019 and March 2020 were included in a prospective cross-sectional study conducted in three participating hospitals. Data were collected using a standardized measurement form. A total of 44 patients were included, in whom TIO-MMF was applied 79 times. A statistically significant difference in intraoperative loss of stability of the segment relationship was found between steel-wire ligatures (11.4%) and power chains (0%).
- Prospective study of the long-term outcomes and complications after total temporomandibular joint replacement: analysis at 10 yearsby A. Rajkumar, A.J. Sidebottom on 07/09/2021 at 12:00 am
This prospective analysis was performed to assess the long-term benefits of the TMJ Concepts joint replacement system in the UK. All patients who had replacement temporomandibular joints (TMJ) with at least 10 years of follow-up were included. The most common primary diagnoses were trauma, multiple previous operations, psoriatic arthritis, rheumatoid arthritis, degenerative disease, and ankylosis. A total of 43 patients (62 joints) were followed up for 10 years (mean age 45, range 22–70 years); 39 were female and four were male.
- Risk factors for oral epithelial dysplasias to become malignant: clinical implicationsby S. Gómez-Armayones, E. Chimenos-Küstner, C. Arranz, S. Tous, S. Marquez, R.M. Penín, B. Quirós, M. Taberna, L. Alemany, O. Servitje, M. Mena on 07/09/2021 at 12:00 am
There is a lack of effective clinical management of oral epithelial dysplasias to reduce their risk of malignant transformation and considerable gaps in knowledge regarding the most effective means of treating such lesions. A retrospective cohort of biopsy-confirmed oral epithelial dysplasias consecutively diagnosed in the period 1995–2014 and followed-up until 2017 was identified from pathology department files. Demographic, clinical and follow-up information was collected. Multivariate Cox proportional-hazards models were performed to evaluate sociodemographic, clinical and pathological factors associated with progression to oral squamous cell carcinoma.
- The role of SPP1 as a prognostic biomarker and therapeutic target in head and neck squamous cell carcinomaby X. Cai, H. Zhang, T. Li on 03/09/2021 at 12:00 am
Head and neck squamous cell carcinoma (HNSCC) is one of the most common malignancies and has a low 5-year survival rate. Mounting evidence suggests that oral potentially malignant disorders, such as oral leukoplakia (OLK), may progress to HNSCC. Given that OLK and HNSCC are often insidious and asymptomatic, the identification of markers of OLK malignant transformation and therapeutic targets in HNSCC is critical. Using various online tools and publicly available gene expression datasets, the secreted phosphoprotein 1 gene (SPP1) was identified as a significant differentially expressed gene among OLK, HNSCC, and non-cancerous tissues.
- Effects of melatonin receptor expression on prognosis and survival in oral squamous cell carcinoma patientsby H.-K. Park, D.-S. Hwang, G.-C. Kim, M.-A. Jang, U.-K. Kim on 02/09/2021 at 12:00 am
Melatonin receptors can inhibit breast and prostate cancers; however, little is known regarding their effects on oral squamous cell carcinoma. In this study, we collected specimens from 81 patients with oral squamous cell carcinoma and analysed clinicopathological data retrospectively. In addition, the expression of the melatonin receptor was analysed immunohistochemically. Survival rates were calculated using the Kaplan–Meier method and log-rank test. Multivariate analysis was performed based on the Cox proportional-hazards model.
- Large cell neuroendocrine carcinoma on the floor of the mouth: a rare entity in an unusual locationby M. Agea Martínez, I. Navarro Cuéllar, A. Sada Urmeneta, F. Alijo Serrano, C. Navarro Cuéllar on 01/09/2021 at 12:00 am
Neuroendocrine carcinomas (NEC) are a group of malignant neoplasms usually located in the lungs or gastrointestinal tract. Fewer cases are located in the head and neck, and in these rare presentations, the lingual tonsil, larynx, and major salivary glands are the most frequently affected sites. NECs exhibit similar characteristics regardless of where they arise. However, because these neoplasms are rare, a clear understanding of their aetiopathogenesis has yet to be described, and options for treatment have varied and are not unified.
- Synchronous oral cavity malignancy in identical twins—unusual coincidence of similaritiesby M. Uddin, A. Bowen, G. Betts, S. Sainuddin on 01/09/2021 at 12:00 am
The multifactorial nature of head and neck squamous cell carcinoma (HNSCC) has led to increased efforts in establishing various risk factors. Well-known environmental risk factors for HNSCC include tobacco use, heavy alcohol consumption, immunosuppression, and more recently human papillomavirus infection. Familial clustering has been observed in cancers occurring at other sites, but not so much with oral squamous cell carcinoma (OSCC) without exposure to shared environmental risk factors. An unusual case of identical twins who presented with OSCC involving an identical site and exhibiting similar histological features is reported here.

- A technique to verify adequacy of eminectomy for recurrent temporomandibular joint dislocationby M.D. Han on 31/08/2021 at 12:00 am
Recurrent dislocation of the temporomandibular joint (TMJ) can be highly debilitating, especially if the dislocation cannot be reduced by the patient. Despite being regarded as a ‘gold standard’ or ‘salvage’ procedure for refractory TMJ dislocations, complete mediolateral removal of the articular eminence can still lead to recurrences. A technique aimed at intraoperatively verifying the adequacy of osseous reduction in order to minimize the risk of re-dislocation of the TMJ is described.
- Supraclavicular lymph node recurrence after radical surgery: is epidermal growth factor receptor a predictive marker?by J.J. Wu, L.W. Ma, C.H. Jiang, J. Chen, N. Li, X.Q. Chen, A.J. Min, W.J. Wang, Y.Q. Hu, X. Gao on 31/08/2021 at 12:00 am
The aim of this study was to evaluate the rare postoperative supraclavicular metastasis originating from oral squamous cell carcinoma (OSCC) and to discuss epidermal growth factor receptor (EGFR) as a potential predictive marker. Tumour specimens of OSCC patients divided into three groups were included: supraclavicular metastasis (n = 8), conventional cervical metastasis (n = 28), no metastasis (n = 48). Basic information and EGFR expression were compared among these groups and the data were analysed to identify potentially related risk factors for supraclavicular metastasis.
- The external jugular vein axis: a new anatomical landmark for pre-operative prediction of the location of parotid gland tumoursby A. Prevost, Z. Cavallier, S. Alshehri, F. Delanoe, F. Lauwers, R. Lopez on 30/08/2021 at 12:00 am
The relationships between parotid tumours and the facial nerve determine duration of surgical procedure and risks involved. As the division of the facial nerve is not visible using standard imaging techniques, other anatomical landmarks are used to determine the pre-operative location of tumours. This retrospective study aimed to evaluate reliability of the ‘external jugular vein axis’ compared with other landmarks generally used in imaging, such as the retromandibular vein, Conn’s arc, the facial nerve line and the Utrecht line.
- The effect of tranexamic acid on blood loss in orthognathic surgery: a randomized, placebo-controlled, equivalence studyby E. Jozefowicz, N. Sabourdin, V. Lambelin, V. Lejeune, R. Delassus, B. Tavernier on 28/08/2021 at 12:00 am
Orthognathic surgery can cause substantial bleeding. Recent meta-analyses concluded that there is a statistically significant reduction in perioperative blood loss with the preventive use of tranexamic acid (TA). However, the mean reported difference in bleeding was moderate, and the clinical relevance of this blood-sparing effect remains debated. We therefore conducted a prospective, double-blind, randomized, placebo-controlled equivalence study of the effect of TA in patients undergoing Lefort I or bimaxillary osteotomies.
- The scope of liquid biopsy in the clinical management of oral cancerby N.T. Baby, A. Abdullah, S. Kannan on 27/08/2021 at 12:00 am
Oral squamous cell carcinoma (OSCC) is one of the most prevalent forms of head and neck cancer, and it remains a leading cause of death in developing countries. Failure to detect the disease at an early stage is the main reason for the lack of improvement in the overall survival rate over the decades. Even though tissue biopsy is considered as the gold standard for diagnosis and molecular workup, it is an invasive, expensive and time-consuming procedure. Besides, it may not indicate the genetic status of the entire tumour owing to the heterogeneity of the cancer.
- Treatment efficacy and prognosis of pulmonary metastasizing ameloblastoma: a systematic reviewby X. Yang, K. Zhou, Y. Tao, S. Ge, W. Shang, K. Song on 27/08/2021 at 12:00 am
The aim of this review was to integrate the current literature into a comprehensive evaluation of pulmonary metastasizing ameloblastoma (MA). Related articles, published since January 2000, were reviewed. The PubMed, Embase, Cochrane Database of Systematic Reviews, and Web of Science databases were searched based on the PRISMA guidelines. Twenty-four studies, including 28 case reports, met the eligibility criteria. The mean ± standard deviation disease-free interval after primary treatment was 12.1 ± 9.3 years.
- Cleft palate lateral synechia syndrome in two patients and literature reviewby S. Plantin, M. Fabre, V. Soupre, A. Guimier, V. Agostini, C.T. Gordon, E. Galliani, A. Picard, A. Morice on 26/08/2021 at 12:00 am
Cleft palate lateral synechia (CPLS) syndrome is an extremely rare congenital malformation syndrome of unknown origin, characterized by the association of cleft palate and one or more intraoral lateral synechiae (OMIM # 119550). Fewer than 20 cases have been described to date. The clinical and histological findings and results of genetic investigations for two additional cases of CPLS are presented herein, in order to better delineate this syndrome, within the context of the relevant literature.
- The effect of subspinal Le Fort 1 corticotomy on nasal morphology in surgically assisted rapid palatal expansionby D. Michaux, E. Van de Casteele, D. Dielen, G. Van Hemelen, N. Nadjmi on 26/08/2021 at 12:00 am
The purpose of this retrospective study was to evaluate the influence of subspinal Le Fort 1 corticotomy (SLF1C) on nasal morphology in patients treated with surgically assisted rapid palatal expansion (SARPE) using three-dimensional (3D) stereophotogrammetry images. A total of 64 patients were enrolled in the study and divided into two groups according to the surgical approach that was used: in group 1 (n = 32) SARPE was performed using a conventional Le Fort 1 corticotomy (CLF1C), and in group 2 (n = 32) SARPE was performed using a subspinal Le Fort 1 corticotomy (SLF1C).
- Primary oncocytic carcinoma of ectopic salivary gland: a unique caseby E. Touli, A. Manganaris, C. Nikolaidou, I. Karasmanis on 25/08/2021 at 12:00 am
Oncocytic carcinoma of the salivary glands is an extremely rare malignant neoplasm. The parotid is the most frequently involved salivary gland, but tumours in the submandibular gland and minor salivary glands have also been described. It appears that oncocytic carcinoma of an ectopic salivary gland has not been reported so far. The unique case of a 78-year-old male patient diagnosed with oncocytic adenocarcinoma of an ectopic salivary gland is reported here. The patient underwent surgery and adjuvant radiotherapy.
- Osteoinductive potential of recombinant BMP-9 in bone defects of mice treated with antiresorptive agentsby M. Fujioka-Kobayashi, S.D. Marjanowski, M. Kono, S. Hino, N. Saulacic, B. Schaller on 25/08/2021 at 12:00 am
The aim of the present study was to investigate the effects of recombinant human (rh)BMP-9 on bone regenerative potential in a mouse model of antibody-mediated antiresorptive therapy (AMART). A monoclonal anti-murine receptor activator of nuclear factor-kappa B ligand (RANKL) antibody (mAb) was used to create an AMART model in mice. rhBMP-9 combined with collagen membrane was implanted in calvarial defects in mAb-treated mice. After 4 weeks, the bone formative potential in the defects was evaluated by micro-computed tomography and histological approaches.
- Local application of the osteogenic inducer sustained-release system promotes early bone remodeling around titanium implantsby J. Chen, D. Lv, Q. Pan, Y. Chen, X. Liu, Y. He on 24/08/2021 at 12:00 am
Enhanced osseointegration and a shortened healing time are required for dental implant treatment. The aim of this study was to evaluate whether topical application of the osteogenic inducer (OI) sustained-release system over the implant promotes early bone remodeling around the implant. The mandibular canines of 15 New Zealand White rabbits were extracted. After 3 months of healing, implants coated with poly(lactic-co-glycolic acid) (PLGA)+OI, PLGA alone, or no material (control) were inserted into the canine sites.
- Three-dimensional condylar displacement and remodelling in patients with asymmetrical mandibular prognathism following bilateral sagittal split osteotomyby B.M. Abotaleb, R. Bi, Y. Liu, N. Jiang, W. Telha, S. Zhu on 23/08/2021 at 12:00 am
This study aims to assess the postoperative condylar displacement and the long-term condylar remodelling in patients with mandibular prognathism with transverse asymmetry after bilateral sagittal split ramus osteotomy (BSSRO). Forty-one consecutive patients (82 condyles) with a transverse mandibular asymmetry of more than 4 mm without occlusal canting treated by BSSRO were included. The preoperative (T1), immediate postoperative (T2) and long-term follow-up of an average of 16.2 months (T3) spiral computed tomography scans were gathered and processed to measure the condylar displacement and remodelling based on cranial base voxel-based and rigid regional registrations.
- Cone beam computed tomography, an overlooked modality in validated image ordering guidelines for odontogenic infectionsby M. Tofangchiha, K. Ramezani on 23/08/2021 at 12:00 am
We read with great interest the article “Validated image ordering guidelines for odontogenic infections” by Weyh et al.1 and appreciate how the authors simplified such an important challenge for practitioners in the field. In their study, the patients with odontogenic infections were divided into four categories of low, moderate, high, and extreme risk based on the risk to the adjacent critical structures or airway. Computed tomography (CT) was defined as necessary for moderate, high, and extreme risk cases.
- Determination of blood loss in bimaxillary surgery: does the formula and the time point affect results?by M. Schwaiger, S.-J. Edmondson, M. Merkl, T. Gary, W. Zemann, J. Wallner on 21/08/2021 at 12:00 am
The amount of blood loss determined in orthognathic surgery differs greatly among studies. This can be attributed to the inhomogeneity in study cohorts analysed, but may also be a result of the varying methodologies used for blood loss determination. However, this has yet to be explored. Thus, the aim of this study was to investigate the extent to which the formula and time point used to measure blood loss affect the blood loss volume, determined in a homogeneous cohort undergoing bimaxillary surgery.
- The effect of acemannan in implant placement with simultaneous guided bone regeneration in the aesthetic zone: a randomized controlled trialby N. Deesricharoenkiat, P. Jansisyanont, V. Chuenchompoonut, N. Mattheos, P. Thunyakitpisal on 21/08/2021 at 12:00 am
Acemannan, a linear polysaccharide produced by Aloe vera, has been shown to have important biological effects promoting wound healing and tissue regeneration. The aim of this randomized clinical trial was to investigate the impact of acemannan in guided bone regeneration (GBR) with simultaneous implant placement. Twenty patients were randomly allocated to a test group (deproteinized bovine bone with particulate acemannan (mean size 32.45 μm)) and a control group (deproteinized bovine bone only).
- Response: Superficial parotidectomy versus extracapsular dissectionby H. Martin, T. Lowe on 20/08/2021 at 12:00 am
We thank the authors for their comments on our recent paper, “Superficial parotidectomy versus extracapsular dissection: literature review and search for a gold standard technique”1.
- The accuracy of magnetic resonance imaging to measure the depth of invasion in oral tongue cancer: a systematic review and meta-analysisby M. Li, Z. Yuan, Z. Tang on 20/08/2021 at 12:00 am
The accuracy of magnetic resonance imaging (MRI)-derived depth of invasion (DOI) compared to histopathological DOI is still controversial. A meta-analysis was performed to address this controversy and further investigate the best imaging sequence to measure DOI of tongue squamous cell carcinomas (SCC). A comprehensive literature search of five electronic databases was conducted. Stata/SE was used to establish a continuous variable model to assess the consistency between MRI-derived DOI and histopathological DOI.
- Extracapsular dissection versus conventional parotidectomy: comparing ‘apples with oranges’?by K. Mantsopoulos, H. Iro on 19/08/2021 at 12:00 am
We write with reference to the article by Martin et al. entitled “Superficial parotidectomy versus extracapsular dissection: literature review and search for a gold standard technique”1. Several recent meta-analyses and reviews have dealt with the optimal form of surgical treatment for benign parotid gland tumours. The increasingly propagated surgical minimum of extracapsular dissection (ECD)2 is being brought face to face with the traditional ‘gold standard’ of facial nerve dissection of varying extent (e.g.
- Salvage surgery for recurrent carcinoma of the oral cavity: assessment of prognostic factorsby Kunal Nandy, Shreya Rai, Supreet Bhatt, Ketul Puj, Priyank Rathod, Abhishek Gangopadhyay on 18/08/2021 at 12:00 am
Salvage surgery is the most acceptable therapeutic option for disease control of loco-regional recurrences in oral cancers. Prognostic factors need to be assessed to select patients for salvage surgery who would benefit the most. This was a single-centre retrospective observational study conducted between 2015 and 2018. A total of 168 patients with recurrent oral cavity carcinoma who underwent salvage surgery were included for analysis. The primary endpoints of the study were to evaluate overall survival (rOS) after salvage surgery and prognostic factors affecting survival.
- Rare anatomical variant of the spinal accessory nerve: case report and comprehensive reviewby S. Mills, C. Aristotelous, L.L. Touil, R.C.W. James on 18/08/2021 at 12:00 am
Historical studies of the anatomy of the spinal accessory nerve (SAN) have reported conflicting results regarding its relationship with the internal jugular vein (IJV). A literature review was undertaken to establish the prevalence of anatomical variations of the SAN encountered during routine neck dissection surgery, in order to increase awareness and reduce morbidity associated with iatrogenic SAN injury. The published literature was analysed by qualitative synthesis and nine articles were yielded following application of the inclusion and exclusion criteria.
- Tumor–stroma ratio is a crucial histological predictor of occult cervical lymph node metastasis and survival in early-stage (cT1/2N0) oral squamous cell carcinomaby S. Huang, H. Cai, F. Song, Y. Zhu, C. Hou, J. Hou on 16/08/2021 at 12:00 am
Occult cervical lymph node metastasis is a significant prognostic factor in patients with early-stage (cT1/2N0) oral squamous cell carcinoma (OSCC). The aim of this study was to investigate the potential value of the tumor–stroma ratio (TSR) as a histological predictor of occult cervical metastasis and survival in early-stage OSCC. This retrospective study included 151 patients who underwent excision of the primary lesion and elective neck dissection from 2013 to 2017. The clinicopathological features of the tumor, risk factors associated with occult neck metastasis, and prognostic factors for overall survival (OS) and disease-free survival (DFS) were studied.
- Are we able to predict airway dimensional changes in isolated mandibular setback?by M.D. Han, F. Antonini, A.M. Borba, M. Miloro on 15/08/2021 at 12:00 am
The goal of this study was to determine whether a relationship exists between the amount of mandibular setback and the amount of airway dimensional changes. Records and cone beam computed tomography (CBCT) of patients who had undergone isolated bilateral sagittal split osteotomy setback between January 1, 2013 and March 16, 2020 at a single institution were reviewed retrospectively. The primary outcome variable was upper airway volume dimension change, and the predictor variable was the magnitude of mandibular setback as measured by six different methods.
- Does different cranial suture synostosis influence orbit volume and morphology in Apert syndrome?by X. Lu, A.J. Forte, M. Alperovich, N. Alonso, J.A. Persing on 13/08/2021 at 12:00 am
This study was performed to compare the orbital and peri-orbital morphological variations in Apert syndrome patients with different cranial vault suture synostosis, so as to provide an anatomic basis for individualized surgical planning. Computed tomography scans of 57 unoperated Apert syndrome patients and 59 controls were subgrouped as follows: type I, bilateral coronal synostosis; type II, pansynostosis; type III, perpendicular combinations of cranial vault suture synostoses. Orbit bony cavity volume was significantly reduced in type I and type II, by 19% (P < 0.001) and 24% (P < 0.001), respectively.
- Prospective study examining the use of thrombin–gelatin matrix (Floseal) to prevent post dental extraction haemorrhage in patients with inherited bleeding disordersby T. Ali, J. Keenan, J. Mason, J.-T. Hseih, M. Batstone on 13/08/2021 at 12:00 am
The bleeding risk in individuals with inherited bleeding disorders (IBDs) during exodontia is traditionally managed with perioperative coagulation factors and/or desmopressin, in conjunction with systemic and topical perioperative tranexamic acid and meticulous primary closure. Factor replacement is costly, requires specialist input, and carries a risk of developing factor VIII (FVIII) inhibitors. This prospective study was performed to determine whether the use of a standardized Floseal and anti-fibrinolytic protocol could reduce postoperative bleeding in patients with IBDs undergoing dental extraction, as compared to factor replacement.
- Does the use of topical anesthetics reduce the perception of pain during needle puncture and anesthetic infiltration? Systematic review and meta-analysis of randomized controlled trialsby F.P.A. Maia, C.A. Araujo Lemos, E.S. de Souza Andrade, S.L.D. de Morais, B.C. do Egito Vasconcelos, E.P. Pellizzer on 11/08/2021 at 12:00 am
The objective of this systematic review was to assess whether the use of topical anesthetics reduces the perception of pain during puncture and anesthetic infiltration. Twenty-two randomized controlled clinical trials, published in English on or before August 6, 2020, were found in the PubMed/MEDLINE, Scopus, and Cochrane Library databases. Risk of bias was determined for randomization and other issues. A total of 1029 patients were evaluated using parameters such as type of topical anesthetic, application site, and pain (measured on a scale).
- Salvage mandibular reconstruction: multi-institutional analysis of 17 patientsby B. Guo, X. Fang, Y. Shan, J. Li, Y. Shen, C. Ma on 09/08/2021 at 12:00 am
Unsuccessful mandibular reconstruction occasionally occurs, leaving the patient with undesirable function and contours. In such cases, second- or third-time corrective operations are challenging. However, published studies on the complicated retreatment of such patients are scarce. A retrospective analysis covering the years 2015–2019 was conducted in three centers. All 17 patients included had undergone prior failed mandibular reconstructions in other institutions. Salvage secondary or tertiary reconstructive surgeries were attempted and the results are presented.
- Transoral retroauricular neck dissection (TREND): A novel combination approachby A. Kudpaje, B. BhanuPrakash, S. Thakur, G. Arakeri, V.U.S. Rao on 07/08/2021 at 12:00 am
Early-stage oral squamous cell carcinoma is treated preferably by wide local tumour excision along with elective neck dissection. The conventional neck dissection leaves an unaesthetic scar, which remains a major challenge that adversely impacts patient satisfaction, their social interactions, and quality of life (QoL). In recent times, retroauricular assisted endoscopic and robotic neck dissection techniques that avoid unaesthetic neck scars have gained popularity. The pitfalls in attaining universal acceptance of these techniques are the need for specialized instrumentation, training, and increased costs.
- Is there any biomaterial substitute for peri-implant soft tissue phenotype modification? A network meta-analysis of the appraisal literatureby V. Moraschini, I.C.C. Kischinhevsky, S.C. Sartoretto, J.A. Shibli, A.T. Dias, R. Sacco, J. Yates, M.D. Calasans-Maia on 06/08/2021 at 12:00 am
Evidence shows that an increased width and thickness of the keratinized mucosa favours peri-implant health. The aim of this network meta-analysis was to compare the clinical effects of alternative biomaterials for peri-implant soft tissue phenotype modification (PSPM) in patients with dental implants when compared to autologous tissue grafts. An electronic search without language or date limitations was performed in four databases and the grey literature for articles published until November 2020.
- Three-dimensional evaluation of long-term skeletal relapse following Le Fort I maxillary advancement surgery: a 2-year follow-up studyby S. Shujaat, E. Shaheen, C. Politis, R. Jacobs on 06/08/2021 at 12:00 am
The aim of this study was to assess relapse following Le Fort I (LFI) maxillary advancement with superior or inferior repositioning at 2 years of follow-up. A total of 50 patients (26 female, 24 male; age range 15–56 years) with skeletal class II or III, who underwent bimaxillary surgery with LFI maxillary advancement in combination with either superior or inferior repositioning and also mandibular advancement/setback, were recruited. Preoperative (T0), immediate postoperative (T1), and 2-year postoperative (T2) cone beam computed tomography scans were acquired.
- Do oropharyngeal throat packs prevent fluid ingestion during orthognathic surgery?by K. Powell, D. Amin, R. Sesanto, A. Bryant, P. Kukreja, P. Waite on 06/08/2021 at 12:00 am
The oropharyngeal throat pack is commonly used in oral and maxillofacial surgery despite debated evidence regarding its barrier function. The study objectives were to investigate whether the oropharyngeal pack reduces blood ingestion and to evaluate its relationship with postoperative nausea and vomiting (PONV) and throat pain. This was a single-center, parallel group, single-blind randomized controlled trial. Participants undergoing orthognathic surgery, age ≥16 years, were included in the study.
- Virtual planning and navigation for targeted excision of intraorbital space-occupying lesions: proposal of a computer-guided protocolby A. Tel, F. Murta, S. Sembronio, F. Costa, M. Robiony on 06/08/2021 at 12:00 am
The purpose of this study was to present an innovative approach for the preoperative assessment and intraoperative targeted excision of masses occupying the intraorbital space based on multimodal image fusion, segmentation, virtual models, digital planning, and navigation. Nineteen patients were studied and underwent surgery using the presented workflow, in both open and endoscopic procedures. Three main scenarios were standardized for the application of computer-guided surgery: single masses of the superior-lateral compartment, single masses of the inferior-medial compartment, and multifocal masses.
- Association between habitual snoring, middle ear disease, and speech problems in young children with non-syndromic cleft palate anomaliesby M. Moraleda-Cibrián, S.P. Edwards, S.J. Kasten, S.A. Warschausky, S.R. Buchman, L.M. O’Brien on 04/08/2021 at 12:00 am
The purpose of this study was to investigate the association between habitual snoring (HS), middle ear disease (MED), and speech problems in children with cleft palate. This cross-sectional study included children aged 2.0–7.9 years with non-syndromic cleft palate anomalies. Parents completed the Pediatric Sleep Questionnaire and a questionnaire about MED. Audiograms and speech assessment were also conducted. Ninety-five children were enrolled; 15.2% of families reported HS, 97.6% MED, and 17.1% speech problems.
- Retrospective analysis of time-related three-dimensional iliac bone graft resorption following sinus lift and vertical augmentation in the maxillaby D. Steller, M. Falougy, P. Mirzaei, S.G. Hakim on 02/08/2021 at 12:00 am
The atrophic maxilla frequently requires bone grafting using an onlay graft (OG) or sinus lifting (SL) before implant rehabilitation. The resorption of bone grafts is influenced by the time until implantation, quality of donor bone, and grafting technique. The aim of this study was to investigate the impact of both grafting techniques on the time-related resorption of autologous iliac bone graft. Forty-three patients underwent either onlay grafting or a sinus lift at 73 sites in the maxilla. Graft height was measured by cone beam computed tomography after augmentation and during follow-up for up to 12 months prior to implant insertion.
- Does the use of a piezoelectric saw improve neurosensory recovery following sagittal split osteotomy?by D.L. Sobol, J.S. Hopper, R.E. Ettinger, T.B. Dodson, S.M. Susarla on 28/07/2021 at 12:00 am
Neurosensory disturbance of the inferior alveolar nerve (IAN) is an adverse effect associated with sagittal split osteotomies (SSO). The purpose of this work was to evaluate neurosensory recovery of the IAN when SSOs were performed with piezoelectric (PZ) versus reciprocating (RP) saws. This was a prospective split-mouth study of patients undergoing bilateral SSO using a PZ saw on one side and an RP saw on the other. The primary outcome of interest was neurosensory recovery, as assessed using the functional sensory recovery (FSR) scale defined by the UK Medical Research Council.
- A magnetic resonance imaging study on the temporomandibular joint disc–condyle relationship in young asymptomatic adultsby D. Luo, Z. Yang, C. Qiu, Y. Jiang, R. Zhou, J. Yang on 27/07/2021 at 12:00 am
The aim of this study was to assess the temporomandibular joint (TMJ) disc–condyle relationship in asymptomatic young adults. Ninety-three volunteers aged 19–23 years without temporomandibular disorder (TMD) symptoms underwent TMJ magnetic resonance imaging (MRI). The condylar centre and apex methods were used to measure and analyse the position of the disc in the oblique sagittal plane, and the reliability of the two methods was compared by calculating the intra-class correlation coefficient (ICC).
