- Should anosmia and dysgeusia be a concern for oral and maxillofacial surgeons during the COVID-19 pandemic?on 05/05/2021 at 12:00 am
Abstract Purpose Dysgeusia and anosmia have been liked to COVID-19 infection. The aim of this study is to study the prevalence of dysgeusia and anosmia in COVID-19 patients treated at the University of Florida Health Center and establish the odds of having an olfactory and gustatory disorder with a confirmed COVID-19 infection. Methods This is a retrospective cross-sectional study utilizing the University of Florida Health Center patients’ registry i2b2 platform to search for ICD 10 diagnoses of COVID-19 infection and taste and smell disturbances. We assessed the odds ratio for patients with dysgeusia and anosmia having a laboratory-confirmed COVID-19 infection using a logistic regression model adjusting for gender, race, age, and comorbidity conditions. P < 0.05 was deemed significant. Results Out of 889 individuals that tested positive for COVID-19, 12.88% were diagnosed with taste and smell disturbances. The odds ratio for COVID-19 for people with dysgeusia and anosmia was 39.107. After adjusting for sex, age, and race, it was 41.9, 37, and 34.2, respectively. Conclusion Taste and smell disturbances in COVID-19 are not anecdotal. It is paramount that oral and maxillofacial surgeons include taste and smell disturbances in the history and physical examination as these symptoms are suspicious of active COVID-19 infection. Patients presenting with an olfactory and gustatory disorder should undergo further evaluations for COVID-19 infection and oral and maxillofacial surgeons should enhance the personal protective equipment used when treating these patients to prevent further spread of the infection and protect other healthcare members.
- Dental injuries in paediatric mandibular fracture patientson 28/04/2021 at 12:00 am
Abstract Purpose Dental injuries (DIs) are associated with facial fractures, particularly mandibular fractures. As paediatric mandibular fractures have special features, we sought to clarify the occurrence and types of DIs among this patient group. We assessed how age, injury type, and fracture location affects the occurrence of DIs and thereby defined which patients are most susceptible. Methods This retrospective study included patients < 18 years with a recent mandibular fracture. Predictor variables were gender, age group, mechanism of injury, type of mandibular fracture, and other associated facial fracture(s). Types and locations of DIs and tooth loss due to injury were also reported. Results DIs were detected in 34.7% (n = 41) out of 118 patients. Patients with tooth injury had on average 3.5 injured teeth. A total of 16.2% of injured teeth were lost, typically at the time of the injury. Loss of at least one tooth was seen in approximately 10% of patients. Avulsion was the most common cause of tooth loss (52.2%). Non-complicated crown fracture (50.7%) was the most common DI type. Statistically significant associations between studied variables and DIs were not detected. Conclusion DIs are common and often multiple in paediatric mandibular fracture patients regardless of background factors. DIs often lead to tooth loss. Prompt replantation of an avulsed tooth, early detection of DIs, and prevention of tooth loss whenever possible are important to avoid permanent tooth defects.
- Reoperative genioplasty: a 10-year retrospective studyon 27/04/2021 at 12:00 am
Abstract Purpose The purpose of this retrospective cohort study was to identify the causes of requiring reoperative genioplasty and determine the factors associated with reoperation. Methods Medical records and radiographs of patients who underwent genioplasty were reviewed. The demographic data, characteristics of operation, and treatment outcomes were gathered to analyze the causes that required reoperation. Descriptive statistics and logistic regression analysis were computed to evaluate the study. Results Of the 157 patients included, there were 12 patients (7.6%) who needed reoperation after genioplasty. Age ≤ 25 years significantly decreased the likelihood for the need for reoperative genioplasty compared with age > 35 years. However, the need for reoperative genioplasty was not directly associated with gender, simultaneous orthognathic operation, direction and amount of movement, method of fixation, or bone graft interposition. Fixation failure, esthetic problems, residual obstructive sleep apnea, and palpable step at the inferior border of the mandible were the causes that required a second operation by reposition and re-fixation with rigid fixation, recontouring, or reoperation by genioplasty. Conclusion Genioplasty procedure provided a predictive result. A reoperative rate was only 7.6% and younger age decreased the risk of reoperative genioplasty.
- Evaluation of the efficacy of laser-assisted flapless corticotomy in accelerating canine retraction: a split-mouth randomized controlled clinical trialon 20/04/2021 at 12:00 am
Abstract Objective To evaluate the efficacy of laser-assisted flapless corticotomy in the acceleration of canine retraction compared with the conventional technique and to evaluate patients’ pain and discomfort levels after corticotomy. Materials and methods A single-center randomized controlled trial was conducted on 18 class II division 1 patients (7 males, 11 females; age range: 16 to 24 years) who required the first-upper-premolar extraction followed by canine retraction. A split-mouth design was used in which the Er:YAG laser-assisted flapless corticotomy was randomly allocated to one side, whereas the other side served as the control side. The primary outcome measure was the canine retraction rate which was assessed immediately after laser application, 1, 2, 4, 8, and 12 weeks after laser application. Also, the levels of pain and discomfort during the first week following laser application were assessed. Paired t-tests or Wilcoxon matched-pairs signed-rank tests were used to detect significant differences. Results All of the selected eighteen patients entered the statistical analysis stage. Significant differences were observed (P < 0.001) in canine retraction rates between the experimental and control sides at the baseline to 1st-week, 1st- to 2nd-week, 2nd- to 4th-week, and 4th- to 8th-week intervals. No significant difference was found between the two sides at the 8th- to 12th-week interval. A significant reduction was seen in the mean score of pain during eating at all assessment times when compared to the baseline data (P = 0.002 at day 2, P < 0.001 at days 5 and 7). Conclusion Er:YAG laser-assisted flapless corticotomy appears to be an effective treatment method for accelerating canine retraction and was accompanied by a mild degree of pain and discomfort.

- Efficacy of collagen-silicone bilayer membrane in the management of oral submucous fibrosis: a prospective case serieson 17/04/2021 at 12:00 am
Abstract Background and objective Oral submucous fibrosis is a scourge of Southeastern Asia since a long time resulting in significant health and social problems. Mainstay of the treatment is concentrated on attempts to improve mouth opening and relieve the symptoms by medicinal or surgical means. In moderate to severe cases, release of fibrous bands is advocated followed by placement of graft. The present study was conducted to evaluate the use of collagen-silicone bilayer membrane as a mucosal substitute in its management. Methodology Study consisted of 12 clinically and histologically proven cases of OSMF. After the incision and release of fibrous bands, a collagen membrane was placed and secured over the raw area by placement of a silicone sheet of adequate thickness. Parameters were assessed pre-operatively, intra-operatively, and post-operatively at 1 week, 1 month, and 3 months. The data was recorded and statistical analysis was done. Results Pre-operatively, the mean values of inter-incisal opening, cheek flexibility, and width of oral commissure were 16.92, 24.58, and 53.17 mm respectively whereas at 3 months post-operatively, it was 27.67, 26.58, and 55.00 mm, which was statistically significant. No incidence of infection was noted. Conclusion The study concludes that the use of collagen membrane along with silicone sheet can be an alternative to other graft materials in context of reduced donor site morbidity as well as significant increase in inter-incisal opening. However, study with more sample size is needed to assess the long-term efficiency and surgical outcome of this material.
- Historical evolution of surgical approaches to the face—part III: lower faceon 17/04/2021 at 12:00 am
Abstract Surgical approaches to the head and maxillofacial area have been described and modified by many authors throughout history. It was, however, during the nineteenth and twentieth centuries when most of the techniques were described, mainly thanks to the advent of anesthesia and antibiotic therapy. Currently, a myriad of surgical techniques are employed to access the maxillofacial complex, with each of them having advantages and disadvantages. Although the approaches are the subject of textbooks and articles, most do not describe the circumstances or the historical context under which they were designed. In a series of three articles, we will provide a historical perspective of the most common surgical approaches to the head and face employed today. Descriptions contain advantages and disadvantages and modifications are provided. The purpose of the present article (3/3) is to review the approaches to the lower face.
- Multi-walled carbon nanotube/hydroxyapatite nanocomposite with leukocyte- and platelet-rich fibrin for bone regeneration in sheep modelon 14/04/2021 at 12:00 am
Abstract Background The aim of this study was to evaluate the effects of multi-walled carbon nanotubes/hydroxyapatite (MWCNT/HA) granules with or without leukocyte- and platelet-rich fibrin (L-PRF) on bone regeneration in cancellous bone of sheep model. Methods Totally, 32 cylindrical holes were drilled in female sheep (n = 4) in the distal epiphysis and proximal metaphysis of right and left humerus and femur. The defects were randomly filled with (1) MWCNT/HA, (2) MWCNT/HA mixed with L-PRF, (3) L-PRF, and (4) left empty as control. After 8 weeks, defects were evaluated and compared radiographically using multi-slice computed tomographic (CT) scan and cone beam CT scans, histologically and histomorphometrically. Results The results showed that there was no significant inflammation (> 10%) or foreign body reaction around the granules. The new lamellar bone was regenerated around the MWCNT/HA nanocomposite granules. Addition of L-PRF to MWCNT/HA demonstrated significantly improvement of new bone formation, about 27.40 ± 1.08%, in comparison with the L-PRF alone, about (12.16 ± 1.46%) (P < 0.01). Also, the rate of new bone formation was significantly greater with the use of MWCNT/HA granules (24.59 ± 1.54%) compared to the control (10.36 ± 1.17%) (P < 0.01). Conclusion Consequently, both biocompatibility and osteoconductivity of MWCNT/HA nanocomposite were demonstrated in the preclinical sheep model, and the use of L-PRF in combination with MWCNT/HA nanocomposite can improve bone regeneration.
- In spite of successful curative surgery for buccal mucosa carcinoma the health-related quality-of-life continues to remain pooron 10/04/2021 at 12:00 am
Abstract Background In early stage buccal mucosa carcinoma, in spite of successful curative surgery, the health-related quality-of-life (HRQoL) may not improve. We aimed to study HRQoL in these patients who had undergone successful curative surgery and determined factors that influence the HRQoL. Methods Subjects, aged 18–70 years, who had undergone successful curative surgery for stage I and II buccal mucosa cancer, were assessed for HRQoL using the University of Washington Quality of Life Questionnaire and factors affecting HRQoL were determined. Their scores were compared with normative reference scores. Results 54 patients (stages I 54%, II 46%) aged 44 ± 11 years (87% males) were studied. They had undergone curative surgery a median of 8.5 (IQR 4–13.5) months ago. Their mean global HRQoL score was 77 ± 30, with significantly poorer scores compared to reference in domains of appearance, activity, swallowing, chewing, speech, shoulder, saliva, mood and anxiety. Anxiety, activity, and chewing were considered the most important domains by the patients. Among the factors influencing HRQoL, duration since surgery was the most important factor, and patients with recent surgery had worse performance in chewing, saliva and mood. Patients with stage II had worse performance in shoulder and anxiety compared to stage I. Post-operative radiotherapy worsened swallowing and shoulder function. Conclusion In spite of successful curative surgery for buccal mucosa carcinoma, the HRQoL continues to remain sub-optimal with poor scores in most of the domains. These domains must be focused on with appropriate measures in order to improve overall HRQoL in patients after successful curative surgery.
- Salvage transorbital approach for the endovascular treatment of carotid cavernous fistulason 05/04/2021 at 12:00 am
Abstract Purpose Carotid cavernous fistulas (CCFs) are abnormal connections between the cavernous sinus (CS) and carotid arteries. In direct CCFs, a transarterial route is often the preferred vascular access; in case of indirect CCFs, the complex anatomy of the feeder vessels and their extra-intracranial anastomosis makes the transarterial embolization challenging and often ineffective. The aim of this study was to review our experience with the transorbital approach to treat patients affected by CCF who have already experienced an endovascular failure procedure, in order to assess this salvage technique feasibility, by analyzing possible risks and complications. Methods We performed a retrospective study of all patients affected by CCFs who underwent transorbital embolization between February 2017 and February 2019 at our institution. Results All patients (3 cases) tolerated both the retrograde embolization and the direct surgical approach with clinical improvement; the closure of the fistula was complete and verified intraoperatively by angiography. Esthetic result was acceptable in all cases with reduction of the proptosis and the intraocular pressure, and increased visual acuity. There were no complications or clinical recurrence. Conclusion Transorbital approach for the endovascular treatment of CCFs is a feasible and safe salvage procedure, which can find indication after other endovascular access failures.
- Management of extensive peri-implant defects with titanium mesheson 29/03/2021 at 12:00 am
Abstract Purpose Peri-implantitis is a biofilm-induced pathological condition, and different approaches have been proposed to manage this condition. This study introduces a surgical technique in accordance with the concept of guided bone regeneration for implants with extensive peri-implant defects. Methods This pilot study was conducted on 7 patients with 11 implants (4 females and 3 males; 32 to 61 years). In this technique, we used a titanium mesh, a combination of autogenous bone, allogenic graft material, and acellular dermal matrix to reconstruct the peri-implant defects. All implants were placed submerged, and the second-stage surgery was conducted after 8 months. Soft tissue augmentation and vestibuloplasty were performed in the second-stage surgery, if required. Results The mean function time of implants was 60.5 ± 29.4 months. The mean baseline probing pocket depth was 5.7 ± 1.4 mm, and soft tissue recession was observed at two sites (18%). The mean recession and keratinized tissue width (KTW) values were 0.4 ± 0.8 mm and 3 ± 1.6 mm, respectively. The mean marginal bone loss and bone gain were 4.4 ± 1.2 mm and 2.9 ± 0.9 mm, respectively, which showed a significant improvement. Conclusion Our preliminary evaluations showed favorable results in terms of radiographic defect fill and soft tissue condition. It appears that this technique may lead to promising outcomes in cautiously selected patients seeking to retain their failing implants. However, long-term results following functional loading are required before recommending this technique for daily practice.
- Genetic polymorphism of tumor necrosis factor alpha ( TNF-α ) and tumor necrosis factor beta ( TNF-β ) genes and risk of oral pre-cancer and cancer in North Indian populationon 29/03/2021 at 12:00 am
Abstract Objective There are inconclusive data connecting single-nucleotide polymorphisms (SNPs) of TNF-α (rs361525) and TNF-β (rs909253) to potential malignant oral disorder (PMOD) such as lichen planus and oral fibrosis. Here, we have investigated the risk of oral squamous cell carcinoma as well as oral pre-cancerous lesions in North Indian population with the polymorphism of the TNFα/ β genes. Material and methods A total 500 patients with oral pre-cancer and OSCC and 500 healthy volunteers were genotypes for the TNF-α (-238) G/A (rs361525) and TNF-β (252) A/G (rs909253) gene polymorphism. Genotypes were identified by polymerase chain reaction (PCR) restriction fragment length polymorphism (RFLP). Genotype frequencies were evaluated by Chi-square test. Results Compared to the GG genotype, the GA genotype of TNF-α (G238A) polymorphism (rs361525) has been found to significantly increase the risk of oral disease (OR = 1.99) and especially the risk of lichen planus and OSCC (OR = 2.805 and 5.790, respectively). Similarly, the risk of oral disease was also more in the heterozygote (AG) than the common allele homozygote (AA) of TNF-β (A252G) polymorphism (rs909253) (OR = 1.483). Conclusion We conclude that the SNPs rs361525 and rs909253 were significantly associated with oral pre-cancer and OSCC.
- Effect of periapical surgery on oral health-related quality of life in the first postoperative week using the Dutch version of Oral Health Impact Profile-14on 24/03/2021 at 12:00 am
Abstract Objective To evaluate whether periapical surgery affects oral health-related quality of life (OHRQoL) within the first postoperative week. Study design The primary outcomes in 133 patients (54 men, 79 women; mean age 50.8 years) undergoing periapical surgery were the Oral Health Impact Profile-14 (OHIP-14) score and postoperative sequelae, including pain, analgesic intake, swelling, limited mouth opening, chewing difficulties, and postoperative infection. Results We found a significant effect on OHIP-14, pain, and analgesics, which decreased throughout the week. We found no significant differences in mean OHIP-14, pain scores, or analgesic use for gender, medical history, surgical flaps, operation time, or location of the operated teeth. Younger patients had a higher OHIP-14 score in the first 2 days after surgery and more pain on the first postoperative day. Women experienced more pain during the first 3 days. Smokers had a higher OHIP-14 score on the first postoperative day and greater pain during the first 3 days compared to non-smokers. Conclusion We identified a low incidence of pain and reduced OHRQoL following periapical surgery. The postoperative reduction in OHRQoL and pain were of short duration, with maximum intensity in the early postoperative period and rapidly decreasing with time.
- Three-dimensional volumetric changes of 5 different bone grafts in human maxillary sinuses reconstruction: a randomized clinical studyon 13/03/2021 at 12:00 am
Abstract Purpose This study aimed to compare the three-dimensional volumetric changes of human maxillary sinuses after reconstruction using 5 different bone grafts. Patients and methods Patients underwent unilateral maxillary sinus bone height reconstruction using 5 bone substitutes allocated in different groups as follows: group 1 was grafted with autogenous bone graft alone; group 2 with beta-tricalcium phosphate (β-TCP); group 3 with β-TCP + autogenous bone graft 1:1; group 4 with bioactive glass; and group 5 with bioactive glass + autogenous bone graft 1:1. The patients were submitted to cone beam computed tomography in two periods: 15 days after the surgical procedure (T1) and after 6 months (T2). The results were evaluated as the formula T2-T1 expressing the three-volumetric changes of the biomaterials in elapsed time. Results The resorption rate of autogenous bone graft was −630.699 ± 300.9 mm3; in the β-TCP group, it was −315.772 ± 125.6 mm3; in the group with β-TCP + autogenous bone graft 1:1, it was −336.205 ± 195.7 mm3; and in groups with bioactive glass and with the addition of autogenous bone graft 1:1, it was −428.878 ± 311.6 mm3 and −576.917 ± 471.6 mm3, respectively, without statistical difference (p = 0.167). Pearson’s correlated test revealed a strong correlation as well as a progressive resorption of the grafts during bone healing. Conclusion The similar outcomes for the three-dimensional volumetric changes using the bone substitutes evaluated after 6 months of bone healing suggest that all these grafts can be performed to maxillary sinus reconstruction.
- Comparative assessment of osteotomy cut using bur and saw for bilateral sagittal split osteotomy of mandible: a prospective clinical studyon 06/03/2021 at 12:00 am
Abstract Purpose To compare the intraoperative utility of bur and saw and to examine the pattern of lingual split during bilateral sagittal split osteotomy of mandible. Material and methods This study prospectively compares the intraoperative utility of bur and saw in bilateral sagittal split osteotomy as split-mouth model. Study includes 16 patients (representing 32 sagittal split osteotomies) divided into two groups. The procedure to be performed was explained to the patient, followed by written informed consent. The institutional ethical committee approved the clinical study and all subjects gave informed consent. Results We found that the ease of handling of the bur was good compared to saw. The duration required for completion of osteotomy using bur was less compared to saw. Conclusions The use of surgical drills and burs is still the gold standard in most developing nations and countries in transition like India. Depending upon the expertise of the surgeon, availability of precise dissecting instruments, one can go with either of the instrument for BSSO.
- A randomized, prospective trial to assess the safety and efficacy of hilotherapy in patients after orthognathic surgeryon 05/03/2021 at 12:00 am
Abstract Purpose A post-operative cooling method in oral and maxillofacial surgery is the cooling with hilotherapy. The aim of this study was the post-operative comparison of cooling temperatures of 18°C and 22°C. The parameters of this trial were swelling and the post-operative pain levels. Methods This study included 156 patients, divided into two groups among whom a mono-one, bignathic osteotomy or genioplasty was indicated. The post-operative assessment of swelling was performed using a 3D optical scanner. This examination was repeated on post-operative days 1, 2, 3, 7, 14, 30, and 90. The examination on day 90 served as a reference value in respect of swelling and pain. Results Group 1 (18°C, 78 patients) showed an increase in post-operative swelling on the 1st post-OP day of 52.06 ± 35.41ml. The maximum was reached on the 2nd post-OP day with 75.82 ± 38.97ml. On the 30th post-OP day, residual swelling measured 11.60 ± 12.62ml. Group 2 (22 °C, 78 patients) showed an increase in postoperative swelling on the 1st post-OP day of 76.07 ± 63.15ml. The maximum was reached on the 2nd post-OP day with 106.97 ± 69.63 ml. On the 30th post-OP day, residual swelling measured 14.36 ± 32.26ml. The differences between the two groups and between different visits were statistically significant. Conclusion The study results indicate less residual swelling in group 1 on the 30th post-OP day, possible based on the lower cooling temperature. The post-operative pain exhibits a comparable level of pain intensity between the two groups. In overall terms, a subjectively more agreeable treatment was observed in group 1.
- Diagnostic and prognostic value of miRNAs on salivary gland tumors: a systematic review and meta-analysison 05/03/2021 at 12:00 am
Abstract Purpose Different levels of miRNA expression have been described in salivary gland tumors as a potential diagnostic marker and predictor of survival. We systematically reviewed the literature to assess the diagnostic and prognostic value of miRNAs on salivary gland tumors. Methods An electronic search was conducted in PubMed, Scopus, Embase, Cochrane, and Web of Science databases. In the meta-analysis, we assumed random-effects model with adjusted hazard ratio (HR) and 95% confidence intervals (95% CI). For prognostic studies, the risk of bias was assessed by Meta-Analysis of Statistics Assessment and Review Instrument (MAStARI) and Quality Assessment Tool for Diagnostic Accuracy Studies-2 (QUADAS-2) was utilized for diagnostic studies. Results Gathered data from 1.131 patients in seven studies demonstrated that different levels of miRNA expression presented diagnostic and prognostic in SGTs. The meta-analysis showed that altered miRNA expression were associated with shortened survival (HR, 2.35, 95% CI, 1.77–3.10, P < .00001). For diagnostic meta-analysis, the overall pooled results for specificity and sensibility were 0.87–0.97 (95% CI, 0.72–1) and 0.68–0.91 (95% CI, 0.51–0.96), respectively. Conclusion MicroRNAs may be useful in prognostication of patients with SGTs; however, the diagnostic value of miRNAs in SGTs is still limited.
- Can CT predict the development of oroantral fistula in patients undergoing maxillary third molar removal?on 01/03/2021 at 12:00 am
Abstract Purpose In maxillary wisdom tooth extraction, the necessity of CT is unknown. The purpose of this study was to investigate whether CT adding to orthopantomography is useful for predicting oroantral perforation during maxillary third molar extraction. Methods Various risk factors for oroantral perforation during maxillary third molar extraction were investigated by univariate and multivariate analyses. We analyzed those of all patients and the patients who underwent CT, respectively. The proximity of the roots to the maxillary sinus floor (root-sinus [RS] classification) and Archer classification were assessed using panoramic radiography. The number of roots and vertical relationship were assessed using CT. Results A total of 604 out of 3299 patients underwent CT adding to orthopantomography. In all cases, multivariate analyses except for CT findings showed that the RS classification type III/IV and the Archer classification Type B/C/D in panoramic findings were significantly correlated with oroantral perforation as radiological findings. In cases for which CT was performed, multivariate analyses showed that one root (OR 12.87) and the vertical relationship Type D (OR 5.63) in CT findings, besides the RS classification type III/IV (OR 4.47) in panoramic findings, were significantly related to oroantral perforation. Conclusion The RS classification and the Archer classification in panoramic findings can predict the risk of oroantral perforation. The usefulness of CT adding to orthopantomography is limited. However, when the relationship between the upper wisdom tooth and maxillary sinus floor (RS classification) is unclear, to check whether the number of roots is one and the apex of one root is projecting into the maxillary sinus in CT findings, is useful for the prediction.
- Reconstruction using sternocleidomastoid muscle flap versus posterior belly of digastric muscle flap compared with no reconstruction following superficial parotidectomyon 01/03/2021 at 12:00 am
Abstract Introduction The most common complications following superficial parotidectomy are formation of contour deformity and development of Frey’s syndrome. Multiple modalities are being used to prevent these complications. We hereby intend to compare the reconstruction modalities (sternocleidomastoid (SCM) muscle flap, posterior belly of digastric (PBD) muscle flap) with) No reconstruction (NR) following superficial parotidectomy. Materials and methods A comparative study was designed which included 15 patients requiring parotidectomy. These patients were divided into three groups viz. SCM, PBD, and NR. The functional outcome (facial nerve involvement, Frey syndrome, ear lobule sensation, neck movements) and the esthetic results were evaluated subjectively and objectively. The outcomes were statistically evaluated using chi-square test and ANOVA test. Results Facial nerve palsy occurred in 2 cases in each group, and all of them recovered completely within 6 months. The Minor starch iodine test was positive in 1 patient in the SCM group, in 2 patients in the PBD group, and in 4 patients in the NR group; only 1 patient of PBD group and 3 patients of NR group complained of gustatory sweating. Neck movements were unaffected in the PBD and NR groups; however, 1 patient complained of mild discomfort and pain during neck movements in the SCM group. Conclusion Primary closure showed the worst results regarding cosmetic deformity. Hence, it is recommended to mandatorily reconstruct the defect. However, the sternocleidomastoid muscle flap is a better cosmetic option compared with posterior belly of digastric muscle flap. In cases with larger defects, a combination of both the flaps can be used. SCM flap also lowers the incidence of Frey syndrome objectively and subjectively with no reported hazard of the spinal accessory nerve and mildly affected neck movements.
- Incidental cervical lymph node metastasis of papillary thyroid cancer in neck dissection specimens from a tongue squamous cell carcinoma patient: a case reporton 01/03/2021 at 12:00 am
Abstract We report a rare case of lymph node metastasis of papillary thyroid cancer (PTC) incidentally detected in a neck dissection specimen of tongue squamous cell carcinoma (SCC). A 42-year-old Japanese woman was diagnosed with tongue SCC (T1N0M0, Stage I). Partial glossectomy with supraomohyoid neck dissection was performed under general anesthesia, and histopathological examinations revealed primary SCC of the tongue and neck metastasis of PTC in neck dissection specimens. A few months later, total thyroidectomy and left modified radical neck dissection were performed by thyroid surgeons. The histopathological diagnosis was PTC of both the thyroid glands. There was no evidence of tumor recurrence or distant metastasis at the 9-month follow-up.
- Oral cavity colon adenocarcinoma metastases: case report with surgical approach and review of more than 30 years literatureon 01/03/2021 at 12:00 am
Abstract Introduction Metastatic oral tumours are rare, contributing to 1% of all malignant oral cavity tumours. Case report We report the case of a 59-year-old man with colon cancer at an advanced disease stage, with progression to the peritoneum and maxillary gingiva. Palliative surgery was indicated to improve the patient’s quality of life. Discussion In a review of the literature, we compiled a list of 27 cases (including the present case) reflecting some 30 years of literature on oral cavity metastatic disease originating in colon cancer. Conclusion Oral cavity metastasis should be taken into account in the differential diagnosis of a synchronous or metachronous oral cavity lesion. The therapeutic goal should include palliative alternatives when necessary. Intraoral reconstruction using local flaps may be a simple and reliable palliative resection option aimed at improving the patient’s quality of life.
