Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to provide guidance on the implementation of a surgical treatment of oral cancer. MEDLINE databases were searched for articles on subjects related to “surgical management of oral cancer” published in English. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. The quality of evidence was rated with use RoBANS (Risk of Bias Assessment Tool for Nonrandomized Studies) and AMSTAR (A Measurement Tool to Assess the Methodological Quality of Systematic Reviews). Evidence-based recommendations for practice were ranked according to the American College of Physicians grading system. Additional directives are provided as expert opinions and Delphi questionnaire when insufficient evidence existed. The Committee developed 68 evidence-based recommendations in 34 categories intended to assist clinicians and patients and counselors, and health policy-makers. Proper surgical treatment selection for oral cancer, which is directed by patient- and subsite-specific factors, remains the greatest predictor of successful treatment outcomes. These guidelines are intended for use in conjunction with the individual patient’s treatment goals.
In case of insufficient voice improvement after injection laryngoplasty (IL), additional IL will be one of the next option of treatments. However, little is known about the voice outcomes regarding an additional IL. Study design: Retrospective comparative study in single institution. Methods: We enrolled the patients of unilateral vocal fold paralysis (UVFP), who received IL (N = 76) twice because of insufficient voice improvement. The etiologies of UVFP were related with thoracic and esophageal surgery (51.3%), neck surgery (30.3%), skull base surgery (7.9%), or unknown (10.5%). The subjective and objective voice parameters were collected before and after (mean: 5.3 months) each IL. Results: Aspiration, maximum phonation time (MPT), jitter percentage, shimmer percentage, and noise to harmonic ratio (NHR) were significantly improved after both the first and second rounds of IL (P < .05). Voice handicap index (VHI)-30 was also significantly improved after both the first and second rounds of IL (P < .001). Regarding GRBAS score, overall grade of dysphonia (G), roughness (R), and breathiness (B) were significantly improved after the first IL, but only G and R after the second IL (P < .05). In comparison between postprocedural voice parameters of the first and second ILs, MPT was significantly improved from 5.5 AE 3.5 seconds to 7.3 AE 7.5 seconds (P = .001). Grade of dysphonia (1.9 AE 0.8) and breathiness (1.7 AE 0.9) of post-first IL were significantly (P < .001) improved to those of post-second IL (1.3 AE 0.7 and 1.2 AE 0.7, respectively). VHI-30 of post-first IL (72.0 AE 20) was significantly improved (P < .001) to those of the second IL (57.2 AE 23.7). Conclusions: In selected patients, additional IL could provide further improvement of voice in patient who had unsatisfactory voice results despite of initial IL.
Hyperparathyroidism is a common endocrine disorder, but intrathyroidal parathyroid adenoma is extremely rare. We report a on a case of hyperparathyroidism caused by intrathyroidal parathyroid adenoma. This case is important in that it affects an effective test for the diagnosis of intrathyroidal parathyroid adenoma, and shows the decision of the treatment process and the results.
Background and Objectives Pilomatricoma is a frequently diagnosed skin lesion of the head and neck that may often be misdiagnosed as other skin lesions. This study evaluated whether ultrasonography (USG) or computed tomography (CT) is the most helpful imaging modality for the accurate preoperative diagnosis of pilomatricoma in head and neck regions of children and adolescents.Subjects and Method A retrospective review was conducted for 59 patients with pilomatricoma under the age of 19 years. All cases were pathologically confirmed with pilomatricoma in the head or neck.Results Preoperative imaging examinations were performed with USG in six cases and with CT in nine cases. The accuracy of preoperative diagnosis was compared between three groups: 1) with clinical findings only, 2) with USG, and 3) with CT. The correct preoperative diagnosis was made in 18 (30.5%) of the total of 59 cases. Using only clinical findings, 10 (22.7%) out of 44 patients were diagnosed as pilomatricoma. With the addition of USG, pilomatricoma was diagnosed in 1 (16.7%) out of six cases, whereas with the addition of CT, 7 (77.8%) out of 9 cases (77.8%) were diagnosed correctly. Preoperative diagnosis of pilomatricoma with CT imaging was more accurate than clinical findings only (vs. CT; odds ratio [OR]=11.900, 95% confidence interval [CI] 2.126-66.615; p=0.001) or USG (vs. CT; OR=17.500, 95% CI 1.223-250.357; p=0.020).Conclusion In the preoperative diagnosis of pilomatricoma, imaging modalities such as CT and USG are helpful, with CT offering higher diagnostic accuracy and USG procedural benefits in younger children.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
