Voice outcome after unilateral ELS type III or bilateral type II resections for T1-T2 glottic carcinoma: Results after 1 year

Abstract Background: Voice outcome was assessed in patients with extended T1 and limited T2 glottic carcinoma, treated with a unilateral type III or a bilateral type II resection according to the European Laryngological Society (ELS) classification. Methods: Objective evaluation (acoustic and aerodynamic parameters), perceptual evaluation (GRBAS), and patients' self-assessment (voice handicap index [VHI]) were performed before and 1 year after treatment. Results were evaluated according to ELS resection type and the involvement of the anterior commissure. Results: The majority of voice parameters in all resection subgroups showed an improvement of the mean score 1 year postoperatively. Grade of dysphonia varied between 1.15 and 1.66 postoperatively and VHI score varied from 23.3 to 24.5. Conclusion: Voice outcome after ELS unilateral type III or a bilateral type II resection for extended T1 and limited T2 glottic carcinoma is good with mild to very moderate perceptive dysphonia and low self-reported voice impairment

Evaluation of the Quality of Reporting of Observational Studies in Otorhinolaryngology - Based on the STROBE Statement

<div><p>Background</p><p>Observational studies are the most frequently published studies in literature. When randomized controlled trials cannot be conducted because of ethical or practical considerations, an observational study design is the first choice. The STROBE Statement (<i>STrengthening the Reporting of OBservational studies in Epidemiology</i>) was developed to provide guidance on how to adequately report observational studies.</p><p>Objectives</p><p>The objectives were 1) to evaluate the quality of reporting of observational studies of otorhinolaryngologic literature using the STROBE Statement checklist, 2) to compare the quality of reporting of observational studies in the top 5 Ear, Nose, Throat (ENT) journals versus the top 5 general medical journals and 3) to formulate recommendations to improve adequate reporting of observational research in otorhinolaryngologic literature.</p><p>Methods</p><p>The top 5 general medical journals and top 5 otorhinolaryngologic journals were selected based on their ISI Web of Knowledge impact factors. On August 3^rd, 2015, we performed a PubMed search using different filters to retrieve observational articles from these journals. Studies were selected from 2010 to 2014 for the general medical journals and from 2015 for the ENT journals. We assessed all STROBE items to examine how many items were reported adequately for each journal type.</p><p>Results</p><p>The articles in the top 5 general medical journals (n = 11) reported a mean of 69.2% (95% confidence interval (CI): 65.8%–72.7%; median 70.6%), whereas the top 5 ENT journals (n = 29) reported a mean of 51.4% (95% CI: 47.7%–55.0%; median 50.0%). The two journal types reported STROBE items significantly different (<i>p</i> < .001).</p><p>Conclusion</p><p>Quality of reporting of observational studies in otorhinolaryngologic articles can considerably enhance. The quality of reporting was better in general medical journals compared to ENT journals. To improve the quality of reporting of observational studies, we recommend authors and editors to endorse and actively implement the STROBE Statement.</p></div

Voice Outcome After Carbon Dioxide Transoral Laser Microsurgery for Glottic Cancer According to the European Laryngological Society Classification of Cordectomy Types - A Systematic Review

Voice outcome after carbon dioxide transoral laser microsurgery (CO2TOLMS) for glottic cancer is of prime importance. However, a comprehensive overview according to the European Laryngological Society (ELS) classification of cordectomies is still lacking. The aim of this systematic review is to summarize data on voice outcome associated with individual types of ELS glottic cordectomy after CO2TOLMS
