- 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).
- A novel instrument for the prevention of condylar torque in bilateral sagittal ramus osteotomy when using bicortical screw fixationby C. Van den Borre, E. Van de Casteele, P. Boeckx, N. Nadjmi on 27/07/2021 at 12:00 am
When using the bilateral sagittal split osteotomy (BSSO) technique, rigid internal fixation (RIF) remains the standard method to accurately fix the distal and proximal osteotomy fragments. A concern with the use of RIF, especially with bicortical screws, is the increased risk of condylar torque and its functional consequences. This technical note introduces a new method for preventing torque of the mandibular condyles after BSSO, using a sagittal split space maintainer.
- Cubik system: maximizing possibilities of in-house computer-guided surgery for complex craniofacial reconstructionby A. Tel, F. Tuniz, S. Sembronio, F. Costa, V. Bresadola, M. Robiony on 23/07/2021 at 12:00 am
Craniofacial reconstruction represents a major challenge due to the complex anatomical morphology. Although implant production has often been outsourced to external companies, in-house planning and manufacturing has developed in many centres. This note introduces a conceptualized modular mould system to perform any desired craniofacial reconstruction, named ‘Cubik’, inspired by the famous Rubik’s cube. A sophisticated virtual process is described that simulates realistic cranio-orbital resections, and the workflow to create multi-component moulds in order to achieve intraoperatively moulded implants is presented.
- The combined coronal–transconjunctival approach: an innovative surgical access for orbital exenteration in craniofacial resectionby J. Acero, P. de Leyva, F. Almeida, J. Núñez, M. Picón on 23/07/2021 at 12:00 am
Malignant tumours arising in the paranasal sinuses or maxilla usually spread to the surrounding regions. The skull base and the anterior cranial fossa are frequently affected as well. When the resection of a tumour involves an orbital exenteration, a transconjunctival-perilimbic incision can be added to a coronal approach in order to preserve the eyelids and the conjunctiva, avoiding cutaneous midfacial incisions. Patients with a diagnosis of malignant tumour affecting the orbit, upper jaw, paranasal sinuses, and/or anterior skull base were eligible for this technique.
- The impact of lymph node density as a predictive factor for survival and recurrence of tongue squamous cell carcinomaby S. Nseir, N. Zeineh, T. Capucha, Y. Israel, O. Emodi, I. Abu El-Naaj, A. Rachmiel on 21/07/2021 at 12:00 am
The oral tongue is considered the most frequently involved site in cases of oral squamous cell carcinoma (OSCC). Lymph node (LN) density, defined as the number of positive LNs divided by the total number of resected LNs, is considered an important prognostic factor in OSCC; however the cut-off point remains uncertain. A retrospective study was performed involving 104 patients who underwent a glossectomy procedure for oral tongue squamous cell carcinoma (OTSCC) between the years 2008 and 2018. LN density and other related prognostic factors, including pathological N-stage (pN), extranodal extension (ENE), perineural invasion (PNI), and depth of invasion (DOI), were investigated in relation to survival and recurrence rates.
- Prognostic significance of lymph node ratio in patients with squamous cell carcinoma of the floor of the mouthby X.C. Liu, S.R. Ma, S. Shi, Y.F. Zhao, J. Jia on 16/07/2021 at 12:00 am
The lymph node ratio (LNR) has been proposed as an independent prognostic factor for survival in patients with oral squamous cell carcinoma (OSCC). However, little attention has been paid to its role in the specific subsite of the floor of the mouth (FOM). The purpose of this study was to evaluate the prognostic significance of the LNR in patients with FOM SCC. A retrospective analysis of 92 patients with FOM SCC who were treated with primary curative resection and neck dissection was conducted.
- Dental implant procedures in immunosuppressed organ transplant patients: a systematic reviewby D. Burtscher, D. Dalla Torre on 14/07/2021 at 12:00 am
During the last decades, the number of immunosuppressed organ transplant patients has increased consistently. Nevertheless, immunosuppression has been discussed as a contraindication for dental implant procedures for many years. Hence, the purpose of this systematic review was to assess the survival rate and outcomes of dental implants after solid organ transplantation. An electronic and manual literature search was conducted up to March 2021. Publications describing dental implants placed in patients after organ transplantation were included without any limitations regarding study design or date of publication.
- Alveolar ridge preservation: an overview of systematic reviewsby C. Aribau-Gumà, A. Jorba-García, A. Sánchez-Torres, M.À. Sànchez-Garcés on 13/07/2021 at 12:00 am
The aim of this overview was to assess the methodological quality of systematic reviews of randomized clinical trials on alveolar ridge preservation after a tooth extraction. During March 2020, two independent reviewers performed an electronic search of the PubMed (MEDLINE), Scopus, Web of Science, and Cochrane Library databases to identify all relevant systematic reviews including randomized clinical trials on alveolar ridge preservation. A manual search of articles in renowned journals was also conducted.
- Does the use of low-level light therapy postoperatively reduce pain, oedema, and neurosensory disorders following orthognathic surgery? A systematic reviewby L.M. Barbosa, J.M. de Luna Gomes, J.R. Laureano Filho, B.C. do Egito Vasconcelos, S.L. Dantas Moraes, E.P. Pellizzer on 05/07/2021 at 12:00 am
The aim of this study was to evaluate the efficacy of low-level light therapy (LLLT) in improving pain, oedema, and neurosensory disorders of the inferior alveolar nerve (IAN) after orthognathic surgery. This systematic review was performed in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Searches were conducted in the PubMed, Embase, and Web of Science databases for randomized clinical trials (RCTs) published up to September 2020. After evaluating eligibility, 15 RCTs were selected.
- Photogrammetric evaluation of corrective surgery for trigonocephalyby R. Kuehle, N. Ewerbeck, T. Rückschloß, O. Ristow, A. El Damaty, C. Freudlsperger, J. Hoffmann, M. Engel on 03/07/2021 at 12:00 am
The aim of this study was to capture preoperative, postoperative, and follow-up head shapes of male trigonocephaly patients who underwent fronto-orbital remodelling (FOR), using three-dimensional (3D) photography. Fifty-seven male infants with metopic synostosis operated on using standardized FOR during a 5-year period were included. All measurements were compared with those of an age-matched healthy control cohort (n = 253 for early postoperative comparison, n = 43 for the 1-year follow-up comparison) to determine the effect of FOR at 14 days and at 1 year post-surgery.
- Outcomes of alveolar segmental ‘sandwich’ osteotomy with interpositional particulate allograft for severe vertical defects in the anterior maxilla and mandibleby C. Chan, A. Mirzaians, B.T. Le on 03/07/2021 at 12:00 am
The purpose of this study was to report the outcomes of interpositional osteotomy with mineralized allograft in the treatment of alveolar vertical defects in preparation for implant placement. Thirteen defects (11 maxillary and two mandibular) were treated with osteotomy segments ranging in length from two to five missing teeth. The segments were positioned 5–7 mm coronally, with the gap space filled with allograft and then fixated with titanium hardware. Vertical bone augmentation was analyzed by superimposing pre- and post-surgical cone beam computed tomography images and stratified based on the length and number of missing teeth in each edentulous segment.
- Assault-related facial fractures: does the injury mechanism matter?by A. Arpalahti, A. Haapanen, T. Puolakkainen, A. Abio, H. Thorén, J. Snäll on 23/06/2021 at 12:00 am
This study clarified the injury characteristics and occurrence of associated injuries in patients with assault-related facial fractures. Data from 840 assault-related facial fracture patients were included; demographic factors, facial fracture type, associated injuries, alcohol use, and injury mechanisms were recorded. Assault mechanisms most often included combinations of different mechanisms (57.5%) and resulted in the victim falling (50.1%). The perpetrator was most commonly a stranger (52.5%) and acted alone (57.7%).
- Characterization and clinicopathological significance of circulating tumour cells in patients with oral squamous cell carcinomaby J. Curtin, S.-W. Choi, P.J. Thomson, A.K.-y. Lam on 18/06/2021 at 12:00 am
Circulating tumour cells (CTCs) are cancer cells released by cancer into the peripheral circulation. Haematogenous tumour spread is a hallmark of metastatic malignancy and a key factor in cancer recurrence and prognosis. CTCs have diagnostic and prognostic significance for a number of adenocarcinomas and melanoma. A review of the published peer-reviewed literature was performed to determine the clinical relevance of CTCs as a biomarker in the management of oral squamous cell carcinoma (OSCC). Fourteen studies met the eligibility criteria.
- The correlation of different methods for the assessment of bone quality in vivo: an observational studyby M.R. Oliveira, A. Gonçalves, M.A.C. Gabrielli, C.R. de Andrade, C.R. Scardueli, V.A. Pereira Filho on 12/06/2021 at 12:00 am
Different methods for the assessment of bone quality were evaluated in this study. Sixty alveolar bone areas were investigated. Peri-apical and panoramic radiographs were obtained with an aluminium scale to assess optical density. The Lekholm and Zarb (L&Z) classification was determined through radiographic analysis and the surgeon’s tactile perception. A trephine was used to obtain a bone biopsy for assessment by micro-computed tomography (micro-CT) and histomorphometry. Primary stability of the implants was assessed using insertion torque (IT) and the implant stability quotient (ISQ).
- Flapped versus flapless alveolar ridge preservation: a systematic review and meta-analysisby M.A. Atieh, L. Alfardan, N.H.M. Alsabeeha on 11/06/2021 at 12:00 am
Alveolar ridge preservation (ARP) procedures can limit bone changes following tooth extraction. Flapped and flapless surgical approaches have been used for ARP; however, there is a lack of strong scientific evidence regarding their specific influences on the clinical outcomes of ARP. The aim of this systematic review and meta-analysis was to evaluate the effects of flapped and flapless surgical approaches on the dimensional changes of hard and soft tissues and patient-reported outcomes following ARP.
- Tomographic evaluation of the mandibular nerve in the mental region and its surgical implications: a cross-sectional studyby C.M.L. Tejada, M. Claudino, L.R. Azevedo Alanis, J.P.L. Manfrinato, S.R. Bernardes, G. Thomé, F.N.G.K. Fontão on 10/06/2021 at 12:00 am
The aim of this study was to evaluate the prevalence and length of the anterior loop (AL) of the inferior alveolar nerve, nerve emergence from the mental foramen, and prevalence of sensory disorders after implant placement in the interforaminal region. Four hundred and fifty hemimandibles (225 patients) were evaluated using cone beam computed tomography and panoramic radiographs. Information on the presence of sensory disorders was obtained from the medical records. AL prevalence was 13.6% and mean AL length was 1.25 mm.
- Interaction between posture and maxillomandibular deformity: a systematic reviewby A. Kerbrat, T. Schouman, D. Decressain, P. Rouch, V. Attali on 10/06/2021 at 12:00 am
Maxillomandibular deformity (MMD) and body posture appear to be correlated. However, no systematic literature review of the available evidence to support this correlation has been performed to date. The aim of this study was to conduct a systematic literature review on posture and MMD. This systematic literature review was registered in the PROSPERO database. Systematic searches of the MEDLINE, Scopus, Cochrane Library, and Web of Science databases were performed. In total, 13 clinical studies were included.
- Synovial entrapment in alloplastic temporomandibular joint replacementby D.F. Ângelo, H.J. Cardoso, D. Sanz on 07/06/2021 at 12:00 am
Complications of alloplastic temporomandibular joint (TMJ) prostheses can lead to stress and anxiety for the patient and the surgical team, and prosthesis substitution is sometimes required. The aim of this case report is to describe the surgical finding of synovial entrapment with interposed fibrosis in a postoperative alloplastic TMJ revision, managed effectively with adequate surgical debridement. The authors believe that synovial entrapment needs to be considered as a possible postoperative complication of total joint replacement when no clear symptoms of infection, metal hypersensitivity, osteolysis, or heterotopic bone formation are present.
- Healing of a large avulsed mandibular bony segment: report of a unique caseby S. Younas, N. Riaz, M. Ehsan-Ul-Haq, S. Mubeen on 05/06/2021 at 12:00 am
This case report puts an emphasis on retaining and re-fixing any avulsed bony segments in the maxillofacial region and maintaining the periosteal layer whenever possible, especially in young patients. Adequate bony fixation and watertight soft tissue closure are vital components for bone healing. The healing potential of facial bones is much higher as compared to the long bones, due to the superior blood supply.
- A new classification of mandibular fracturesby J.S. Brown, A. Khan, S. Wareing, A.G. Schache on 04/06/2021 at 12:00 am
There is no accepted method of reporting mandibular fracture that reflects incidence, treatment and outcome for individual cases. As most series include anatomical site only for all fractures, the aim was to establish a new method to report fractures based on a systematic review of the literature and an internal audit. The classification proposed is: Class I; condyle, II; angle, IIc; II+condyle, III; body/symphysis, IIIc; III+condyle, IV; multiple fractures not including condyle, IVc; IV+condyle, V; bilateral condyle±other fracture(s).
- Corrigendum to “An ectomesenchymal chondromyxoid tumour on the lateral border of the tongue” [Int J Oral Maxillofac Surg 49 (2020) 1290–1203]by K. Sakurai, K. Nakamori, M. Yamazaki, J.-I. Tanuma on 04/06/2021 at 12:00 am
The authors regret that although we stated “four cases with lesions involving the floor of the mouth and two with lesions involving the hard palate have been reported”, none actually involved the oral floor. We erroneously called the base of the tongue as the floor of the mouth. Therefore, we would like to correct this to “four cases with lesions involving the base of the tongue and two with lesions involving the hard palate have been reported”.
- In-office 3D printed guide for rhinoplastyby C. Guevara, M. Matouk on 03/06/2021 at 12:00 am
Rhinoplasty is one of the most technically challenging aspects of facial cosmetic surgery. Various versions of predictive computer software have been developed to aid the surgeon in obtaining predictable results. In the rapidly progressing era of three-dimensional (3D) printing, we present an intraoperative technique that has enabled us to reliably monitor planned surgical changes to the nasal form.
- Parapharyngeal metastasis in hepatocellular carcinoma—a rare entityby J. Chee, G.H. Lee, L.Y. Ooi, J.E. Seet, T. Loh, L.S. Ng on 02/06/2021 at 12:00 am
Hepatocellular carcinoma (HCC) is the most common primary malignancy of the liver. It most commonly metastasizes haematogenously to the lungs and bones, less commonly via lymphatics to lymph nodes. However, metastasis to the parapharyngeal space has yet to be reported. This is the first clinical report of the treatment of parapharyngeal metastasis from HCC. The case of a 46-year-old man who was found to have a parapharyngeal soft tissue mass during routine follow-up 12 years post deceased-donor liver transplantation for hepatitis B-related HCC is reported here.
- A SEER analysis of survival and prognostic factors in merkel cell carcinoma of the head and neck regionby C.C. Go, D.H. Kim, C.A. Briceño on 02/06/2021 at 12:00 am
While Merkel cell carcinoma (MCC) of the head and neck is highly malignant, it remains poorly characterized due to its rarity. The purpose of this study was to examine prognostic factors for overall survival (OS) and disease-specific survival (DSS) in patients with MCC of the head and neck region. The Surveillance, Epidemiology and End Results registry was reviewed for patients diagnosed between 1984 and 2016 with histologically confirmed, primary MCC of the head and neck region. A total of 2818 patients met the inclusion criteria, with a median age at diagnosis of 77 years.
- Efficacy of platelet-rich fibrin and tacrolimus on facial nerve regeneration: an animal studyby S.I. Mourad, S.A. Al-Dubai, S.A. Elsayed, R.R. El-Zehary on 02/06/2021 at 12:00 am
This study was performed to investigate the effect of platelet-rich fibrin membrane (PRFM), alone and with topical tacrolimus application, on regeneration of the crushed facial nerve (FN). Thirty healthy 7-week-old albino rats were used. The left FN was damaged by crushing in all rats. Three random groups of rats were formed: group 1, untreated; group 2, treated with PRFM; group 3, treated with PRFM plus topical tacrolimus. Functional recovery and histological and immunohistochemical evaluations were performed 4 and 8 weeks later.
- Pain management at iliac donor sites after grafting of alveolar cleftsby A. Tache, M.Y. Mommaerts on 02/06/2021 at 12:00 am
The aim of this study was to answer the question: which analgesic protocol is most efficient and most effective in overcoming pain and promoting functional recovery after iliac bone grafting in cleft alveolus patients? A systematic review of the literature was performed. The population consisted of cleft lip and alveolus patients with or without cleft palate undergoing iliac crest bone grafting; the outcomes analysed were represented by the duration of hospital stay, subjective pain rating, and degree of impaired mobility.
- Evaluation of anatomical references for locating the course of the posterior superior alveolar artery for dental implant surgeryby A. Takahashi, K. Kamada, T. Kudoh, K. Kudoh, N. Takamaru, N. Kurio, C. Sugawara, Y. Miyamoto on 31/05/2021 at 12:00 am
This retrospective cohort study aimed to identify the best anatomical reference for predicting the posterior superior alveolar artery (PSAA) location. Computed tomographic images of 90 maxillary sinuses were evaluated. We studied five references, including the alveolar crest, maxillary sinus floor, zygomatoalveolar crest, hard palate and soft palate, and measured the distances between them and the PSAA. Variations in the distance were evaluated by the standard deviation and coefficient of variation (CV).
- Patients’ views of physical activity whilst living with and beyond head and neck cancerby S.N. Rogers, D. Lowe, A.W. Midgley on 31/05/2021 at 12:00 am
Exercise is an important component of recovery following cancer. Head and neck cancer (HNC) patients typically report low levels of engagement in exercise initiatives. The aim of this study was to give insight into HNC patients’ reflections on how and why they would be interested in participating in an exercise programme. A stratified sample of 51 patients based on age, gender and initial interest in an exercise programme was selected from 430 postal survey respondents. Twenty-five took part in a semi-structured telephone interview.
- Patient- and clinician-reported outcomes for the additively manufactured sub-periosteal jaw implant (AMSJI) in the maxilla: a prospective multicentre one-year follow-up studyby C. Van den Borre, M. Rinaldi, B. De Neef, N.A.J. Loomans, E. Nout, L. Van Doorne, I. Naert, C. Politis, H. Schouten, G. Klomp, L. Beckers, M.M. Freilich, M.Y. Mommaerts on 29/05/2021 at 12:00 am
The clinical outcomes of maxillary rehabilitation with the additively manufactured sub-periosteal jaw implant (AMSJI; CADskills BV) were evaluated in edentulous patients with a Cawood–Howell atrophy classification ≥5 in all regions of the maxilla. Fifteen consecutive patients were included in the study and followed up for 1 year. They were interviewed using a survey protocol and were examined clinically and radiographically preoperatively (T0) and at 1 (T1), 6 (T2), and 12 (T3) months after permanent upper prosthesis placement.
- The need for secondary orthognathic surgery after high condylectomy in patients with active unilateral condylar hyperplasiaby T. Aerden, L. Verstraete, C. Politis on 29/05/2021 at 12:00 am
The need for secondary orthognathic surgery (OS) after a high condylectomy (HC) in patients with active unilateral condylar hyperplasia was assessed in 25 patients, reviewing patient characteristics and treatment planning. At 6–12 months after HC, 13 patients (52%) required secondary OS. The amount of mandibular dental midline shift before the HC (P=0.037), and a dental crossbite that was present before the HC (P=0.017) were significantly associated with the need for secondary OS. Overall, the mandibular dental midline coincided with the facial midline in eight patients (32%) at 2 weeks after HC.
- Recurrent mandibular fractures: a retrospective study over 17 years on aetiology, demographics, fracture patterns, and managementby J. Sadhu Reddipogu, E. Lightfoot, C. Scott, M. Thomas on 29/05/2021 at 12:00 am
Recurrent fractures of the mandible are rare, however in Darwin, Australia, their occurrence is relatively frequent. This retrospective study identified 127 patients with 148 recurrent mandibular fractures treated at Royal Darwin Hospital between 2000 and 2017. Age, sex, ethnicity, marital status, aetiology, risk factors, anatomical location of the fractures, fracture patterns, and management of the fractures were analysed. The majority of patients were male (85.8%) (P < 0.001); 62.8% were unmarried (P < 0.001) and 72.4% were indigenous (P < 0.001).
- Are women more susceptible than men to iatrogenic inferior alveolar nerve injury in dental implant surgery?by E. Pääsky, A. Suomalainen, I. Ventä on 29/05/2021 at 12:00 am
An over-representation of women in dental implant-related inferior alveolar nerve injuries (IANIs) is recognized in the literature but has not been investigated. Therefore, a nationwide retrospective register study was conducted to analyse how IANIs compare with other implant-related complications (infection, implant malposition, lack of bone at implant site, mechanical damage, or failed osseointegration) separately in women and men. Financially compensated malpractice claims related to dental implant surgery were collected from the Finnish Patient Insurance Centre for the years 1997—2013, while the total number of nationally placed implants was ascertained from the implant register held by the Finnish Institute for Health and Welfare.
- Microvascular reconstruction of the mandible with medial femoral condylar flap for treatment of mandibular non-unionby F. Arcuri, M. Innocenti, G. Menichini, C. Pantani, M. Raffaini on 28/05/2021 at 12:00 am
Mandibular non-union occurs in 2–9% after open reduction and internal fixation of a mandibular fracture (trauma surgery, orthognathic cases, access osteotomy for oncological purposes). The medial femoral condyle (MFC) has emerged more recently as one of the most versatile donor sites in the treatment of challenging bone reconstruction. This is the first description of MFC for treatment of mandibular non-union. A retrospective chart review was conducted for all patients who underwent reconstruction with a microvascular MFC flap for bone defects of the head and neck area between January 2015 and December 2018 at Careggi Hospital of Florence.
- The impact of complex facial surgery provided on a short-term surgical missionby A.O. Jenkinson, M. Fell, M. Eshete, V. Patel, Y. Demissie, F. Abate, M. McGurk on 28/05/2021 at 12:00 am
The long-term consequences of performing facial surgery on patients living in rural Ethiopia are largely unknown. A review of 36 patients who had been treated on a short-term surgical mission (STSM) in the previous 2 years was conducted to evaluate the outcomes of the surgical interventions performed. There was a significant reduction in social isolation following a surgical intervention. Improvements in postoperative self-reported changes were found for facial appearance, facial function, and quality of life.
- Oncologic safety of submental island flap reconstruction in clinically node-negative oral cancer patients: a prospective comparative studyby A. Mishra, N. Mishra, D. Pati, D. Samal, I.B. Kar, D. Mohapatra, D.F. Sarkar on 28/05/2021 at 12:00 am
The purpose of this study was to evaluate the oncologic safety of submental island flap (SIF) reconstruction in clinically node-negative oral cancer patients. Forty-four clinically node-negative oral cancer patients with tumour size T1–T3 were divided into two groups. The Submental group consisted of 21 patients, who underwent submental island flap reconstruction whereas the control group consisted of 23 patients who underwent reconstruction with other locoregional or free flaps. The locoregional recurrence rate (LRR) and recurrence-free survival (RFS) in these two groups were assessed and compared.
- Mechanical evaluation of a patient-specific additively manufactured subperiosteal jaw implant (AMSJI) using finite-element analysisby E. De Moor, S.E.F. Huys, G.H. van Lenthe, M.Y. Mommaerts, J. Vander Sloten on 28/05/2021 at 12:00 am
Edentulism with associated severe bone loss is a widespread condition that hinders the use of common dental implants. An additively manufactured subperiosteal jaw implant (AMSJI) was designed as an alternative solution for edentulous patients with Cawood and Howell class V–VIII bone atrophy. A biomechanical evaluation of this AMSJI for the maxilla in a Cawood and Howell class V patient was performed via finite-element analysis. Occlusal and bruxism forces were incorporated to assess the loading conditions in the mouth during daily activities.
- Maxillomandibular osteotomy healing in a patient with hypophosphatemic ricketsby J. Ponto, D. Farkas, J.D. Segal, Y. Yusupov on 25/05/2021 at 12:00 am
Hypophosphatemic rickets is a hereditary disease of childhood that affects bone metabolism. Patients with this disease can have poor bony healing at growth centers due to impaired mineralization of the cartilaginous bone plates. The orthopedic literature has shown appropriate long bone healing in patients with rickets who are undergoing concurrent medical management. However, there has never been a report of successful osteotomy or fracture of the maxillomandibular skeleton in a patient with rickets with documented radiographic and clinical resolution.
- Oncological outcomes of total glossectomy procedure for advanced tongue cancer: a single-centre experienceby H. Nemade, A. Chaitanya S, S. Kumar, A.K. A, T.S. Rao, L.M.C.S. Rao S on 18/05/2021 at 12:00 am
Surgeons treating advanced carcinoma of the tongue with total glossectomy face many conflicts in view of the morbidity and poor functional and survival outcomes following surgery. It is pertinent to study the patients undergoing total tongue compartment resection as a separate cohort to analyse their outcomes. This study investigated the oncological outcomes of 150 patients with advanced tongue squamous cell carcinoma who underwent total glossectomy. The results suggest that compartment resection significantly improved local control, irrespective of margin status.
- Non-surgical treatment of vertical excess of the premaxilla in growing bilateral cleft lip and palate patientsby M.C. Meazzini, N. Cohen, L. Autelitano, J. Radojicic on 12/05/2021 at 12:00 am
Patients with bilateral complete cleft lip and palate (BCLP) may present a vertical excess of the premaxilla in childhood. This is a severe functional and aesthetic problem, where bone grafting is more challenging. The aim of this study was to describe a simple and reproducible non-surgical orthopaedic treatment for vertical excess of the premaxilla in the deciduous/early mixed dentition phase in BCLP patients. Six growing patients with complete BCLP with a severe vertical excess of the premaxilla were included.
- Penetration of inferior alveolar nerve canal increased by bicortical fixation after bilateral sagittal split osteotomy in mandibular prognathismby S.P. Sinha, T.D.H. Duong, T.-D.T. Duy, E.W.-C. Ko, Y.-R. Chen, C.S. Huang on 11/05/2021 at 12:00 am
The purpose of this three-dimensional cone beam computed tomography (CBCT) study was to identify the difference between monocortical fixation (MCF) and bicortical fixation (BCF) in mandibular canal penetration after bilateral sagittal split osteotomy (BSSO) to correct mandibular prognathism, where interosseous fixation was done by BCF or MCF. CBCT was performed 1 week postoperatively and Dolphin 3D software was used to assess direct penetration of the mandibular canal by either type of screw. The primary outcome variable was the presence or absence of mandibular canal penetration and was categorized as a binary coded variable.
- Pre-autotransplantation alveolar process augmentation and premolar autotransplantation as a treatment method for single tooth replacement in adolescentsby J.P. Verweij, J.T. Wes, R.A. van Teeseling, A.G. Becking on 10/05/2021 at 12:00 am
The treatment of young patients with missing teeth and an atrophied alveolar process after trauma or agenesis of a tooth can be challenging. The aim of this study was to evaluate autotransplantation of a premolar after pre-autotransplantation alveolar process augmentation (PAPA) as a treatment option for these patients. A retrospective cohort study was implemented to analyse the PAPA procedure and subsequent autotransplantation procedure. Alveolar process augmentation was performed using different types of autologous bone grafts.
- Benefits of the enhanced recovery after surgery pathway for orthognathic surgeryby M. Stratton, P.D. Waite, K.K. Powell, M.M. Scopel, P. Kukreja on 06/05/2021 at 12:00 am
The enhanced recovery after surgery (ERAS) protocol was designed to improve patient outcomes and decrease complications, opioid use, and postoperative nausea and vomiting (PONV). The aim of this retrospective cohort study was to examine the effectiveness of ERAS protocols implemented in orthognathic surgeries from 2017 to 2018 at the University of Alabama at Birmingham Hospital by measuring opioid use and PONV. Two groups were identified through chart review, a non-ERAS group (traditional) of patients who had surgery without a protocol and an ERAS group of patients who had surgery with the ERAS protocol.
- Texture analysis of cone beam computed tomography images reveals dental implant stabilityby A.L.F. Costa, B. de Souza Carreira, K.A.C. Fardim, A.D. Nussi, V.C. da Silva Lima, M.M.V. Miguel, M.A.N. Jardini, M.P. Santamaria, S.L.P. de Castro Lopes on 04/05/2021 at 12:00 am
The aim of this study was to characterize the alveolar bone of edentulous maxillary sites using texture analysis (TA) of cone beam computed tomography (CBCT) images and to correlate the results to the insertion torque, thus verifying whether TA is a predictive tool of final implant treatment. This study was conducted on patients who had received single implants in the maxilla (46 implants) 1year earlier and whose torque values were properly recorded. Three cross-sections of the sites were selected on CBCT scans.
- SH3BP2-related fibro-osseous disorders of the maxilla and mandible: A systematic reviewby J. Kueper, C. Tsimbal, B.R. Olsen, L. Kaban, E.C. Liao on 30/04/2021 at 12:00 am
Cherubism is a disorder of bony overgrowth of the jaws that manifests in childhood. SH3BP2 gene variants have been associated with cherubism; this gene plays a major role in bone homeostasis. Due to its rare occurrence, there is as yet no comprehensive understanding of the natural history and clinical course of the disease. The aim of this review was to compile and analyze all cases of SH3BP2-related cherubism and cherubism-like disorders. Thirty publications were identified, including 92 individuals from 34 families, who were diagnosed with SH3BP2-related fibro-osseous lesions of the jaw.
- Accuracy of mandibular proximal segment position using virtual surgical planning and custom osteosynthesis platesby J. Harding, J.K. Hartsfield, A.S. Mian, B.P. Allan, S. Naoum, R.J.H. Lee, M.S. Goonewardene on 30/04/2021 at 12:00 am
The purpose of this study was to determine whether the use of custom osteosynthesis plates increased the accuracy of proximal segment position following bilateral sagittal split osteotomy in a cohort of 30 patients when compared to a control group of 25 patients who had surgery with conventional plates. Surgery was performed by a single surgeon between October 2015 and December 2017. Post-surgical cone beam computed tomography scans were segmented using Mimics Innovation Suite (Materialise NV), and surface-based superimposition was achieved using ProPlan CMF (Materialise NV).
- Posterior occipital gunshot wound causing orbital roof blow-in fracture with encephaloceleby N. Callahan, L. Moles on 29/04/2021 at 12:00 am
Isolated orbital roof fractures are rare fractures that usually occur in conjunction with other facial bone fractures during high velocity trauma. This report concerns a patient with an isolated orbital roof fracture with encephalocele, including its diagnosis, surgical management, and clinical follow-up. This case required a multidisciplinary approach to safely repair the fracture, reduce the encephalocele, restore the orbital volume, and restore the patient’s form and function.
- Soft tissue-based registration of intraoral scan with cone beam computed tomography scanby J.T. Deferm, J. Nijsink, F. Baan, L. Verhamme, G. Meijer, T. Maal on 28/04/2021 at 12:00 am
The aim of this study was to evaluate a novel soft tissue-based method to register an intraoral scan (IOS) with a cone beam computed tomography (CBCT) scan. IOS and CBCT data were obtained from eight dentate patients (mean age 21±2 years; three male, five female) and 14 fully edentulous patients (mean age 56±9 years; eight male, six female). An algorithm was developed to create a soft tissue model of the CBCT scan, which allowed a soft tissue-based registration to be performed with the IOS. First, validation was performed on dentate jaws with registration of the palatal mucosal surface and accuracy evaluation at the level of the teeth.
- Removal of patient-specific reconstruction plates after mandible reconstruction with a fibula free flap: is the plate the problem?by K. Kreutzer, C. Steffen, S. Nahles, S. Koerdt, M. Heiland, C. Rendenbach, B. Beck-Broichsitter on 28/04/2021 at 12:00 am
Computer-aided microvascular mandible reconstruction is an increasingly common procedure in oral and maxillofacial surgery. The aim of this retrospective single-centre study was to evaluate the rate and specifics of hardware removal after fibula free flap (FFF) fixation with a patient-specific reconstruction plate. The study included patients who underwent hardware removal between April 2017 and October 2019. Statistical analyses were performed regarding the different indications for plate removal (dental implantation versus complication) and the surgical approach (intraoral versus extraoral).
- Diffusion-weighted imaging with histogram analysis of the apparent diffusion coefficient maps in the diagnosis of parotid tumoursby A.A.K. Abdel Razek, B.N. Gadelhak, I.A. El Zahabey, G.A.E.A. Elrazzak, B. Mowafey on 21/04/2021 at 12:00 am
The aim of this study was to investigate the role of diffusion-weighted imaging (DWI) with histogram analysis of apparent diffusion coefficient (ADC) maps in the characterization of parotid tumours. This prospective study included 39 patients with parotid tumours. All patients underwent magnetic resonance imaging with DWI, and ADC maps were generated. The whole lesion was selected to obtain histogram-related parameters, including the mean (ADCmean), minimum (ADCmin), maximum (ADCmax), skewness, and kurtosis of the ADC.
