The aim of the present study was to assess the accuracy, surface texture, marginal adaptation, patient satisfaction, and ease of fabrication of silicone auricular prostheses fabricated by the rapid prototyping technology (RPT) when compared to the conventional method (CM). Materials and Methods: A pilot study was conducted on five patients who had partial auriculectomy defects. Ear prostheses fabricated by CM and RPT were compared. RPT include the fabrication of prostheses by the duplication of polymer model fabrication or by injecting silicone to mold obtained by Vacuum casting method (VCM). The prostheses were evaluated by 15 randomly allotted trained independent observers based on the Likert Scale. The patients performed a self-rating assessment followed by a report from the clinician and technician. Statistical Analysis: The scores for each of the dimension were analyzed using the ANOVA. The cost, time, and quantity of silicone material were expressed in means for three fabrication methods. Results: Prostheses fabricated by RPT yielded superior scores in terms of accuracy, texture, and marginal fit; the vacuum casted prostheses being more precise. The patient perspective was in favor of RPT though not significant statistically. Time for fabrication and number of patient visits were less for rapid prototyping methods than CM. Conclusion: The present study demonstrated the potential benefits of digital method in the fabrication of auricular prosthesis using RPT in the field of maxillofacial rehabilitation.","PeriodicalId":41774,"journal":{"name":"Journal of Head & Neck Physicians and Surgeons","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46676341","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It can be fatal by causing severe bleeding or interference with the airway. Objectives: The objectives of this study were to assess the etiology, site, timing, age, and gender predilection of maxillofacial trauma in a sample of Sudanese patients. Materials and Methods: This was a prospective descriptive-analytical hospital-based study. The records of 96 trauma patients who attended Khartoum Dental Teaching Hospital from February to April 2017 were investigated for the following information: the etiology of the trauma, site of the fracture, time of the injury as well as the patients’ age and gender. Data were analyzed using the Statistical Package for the Social Sciences software (IBM Corp., Armonk, NY USA). Results: During the study period, 96 patients with 204 fractures were treated. 82.3% of the patients were males. The age group between 13 and 23 years showed the highest rate of incidence of maxillofacial trauma. The most common cause of the trauma was assault (36.5%) in males and falls in females (47.1%). Dentoalveolar fractures were the most common site of fractures (25.6%) followed by condylar fractures (14%). The majority of the injuries (34.4%) took place during the day between 1 pm and 6 pm. Conclusions: Causes and patterns of maxillofacial trauma vary greatly from one region to another. This can remarkably aid in raising public awareness and establishing specific prevention and treatment programs.","PeriodicalId":41774,"journal":{"name":"Journal of Head & Neck Physicians and Surgeons","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45310076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Materials and Methods: A cross-sectional study was undertaken with 50 study participants after defined inclusion and exclusion criteria as per the study needs and imaging limitations. Sonographic and sonoelastographic examination was done by two examiners and diagnosis was reached in consensus. Sonographic features assessed were size, short/long axis ratio, presence or absence of echogenic hilum, intra-nodal necrosis including pattern of vascularity. With ultrasonoelastography, color-coded elastograms and strain ratio (SR) were evaluated. Then, the accuracy of individual sonographic and sonoelastographic parameters as well as combined sonographic and sonoelastographic evaluation were evaluated against histopathological examination diagnosis. Cutoff for all the combined evaluation was determined from the receiver operating characteristic curve. Results: Sensitivity of individual sonographic parameters ranged from 81% to 96.3%, whereas specificity was from 50% to 96.3%. Maximum accuracy of 94.3% was obtained with intra-nodal necrosis and echogenic hilum individually. Color-coded elastograms with pattern >3 suggesting metastatic showed sensitivity of 100% but specificity of 75%. Maximum accuracy was achieved by SR >1.99 with 96.3% sensitivity and 93.02% specificity. Combined ultrasonography evaluation had sensitivity of 70.4% and specificity of 87.5%, whereas combined sonographic plus elastographic evaluation increased sensitivity and specificity to 92.6% and 100%, respectively. Conclusion: Combined sonographic and sonoelastographic assessment is better than individual assessment; hence, elastographic findings complement sonographic assessment and further increases the diagnostic confidence.","PeriodicalId":41774,"journal":{"name":"Journal of Head & Neck Physicians and Surgeons","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41336316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Settings and Design: A prospective observational anatomical study. Materials and Methods: The relationship of ZT to RLN was studied, and the size of the ZT was measured and graded according to Pelizzo’s grading system in all cases of routine thyroidectomy in 36 patients (45 sides) from December 2018 to November 2019. Results: ZT was present in 32 (71.11%) of the sides, more commonly on the right side in 24 (88.89%) with a P value of 0.001. Among the total thyroidectomy, bilateral ZT was present in 7 cases (77.78%). In the 45 sides Grade 0 was noted in 13/45 (28.89%), Grade I 14/45 (31.11%), Grade II 9/45 (20%), and Grade III 9/45 (20%) with a P value of 0.001. ZT more than 0 but less than 1 cm was the most common occurrence (Grade I and II). In the 32 sides which had ZT, 23/32 (71.88%) were Type A (posterior) and 9/32 (28.12%) were type D (lateral) with a P value of 0.01. Conclusions: The identification and meticulous dissection of ZT ensures completeness of thyroidectomy. As the size of the ZT increases, the nerve often runs posterior and medial to surface of ZT. The site of ZT can be considered an eloquent area in thyroid surgery as it lies in proximity to the RLN and superior parathyroid gland.","PeriodicalId":41774,"journal":{"name":"Journal of Head & Neck Physicians and Surgeons","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43400642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many newer techniques of radiation have evolved, but esophageal stricture still remains a complication, especially in a concurrent chemoradiation setting. The treatment options in such conditions can be either invasive or noninvasive. We present a reconstructive option in the form of islanded facial artery myomucosal (iFAMM) flap which carries less donor site morbidity and also provides a mucosal lining. A patient with carcinoma hypopharynx reported with dysphagia following concurrent chemoradiation. The patient was evaluated clinically (video-laryngoscopy, esophago-gastro-duodenoscopy, and video-fluoroscopy) and radiologically and diagnosed as stricture cervical esophagus. The patient had undergone repeated noninvasive techniques of dilatation and failed. Stricture release and patch pharyngoplasty were done with iFAMM flap. Till the last follow-up of 1 year, the patient showed satisfactory deglutition with normal voice. iFAMM is a viable and esthetically appealing option for reconstruction of partial postradiation hypopharynx and cervical esophagus stricture of up to 6 cm in length that are not amenable to dilatation procedures.","PeriodicalId":41774,"journal":{"name":"Journal of Head & Neck Physicians and Surgeons","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47385514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
