<p class="abstract"><strong>Background:</strong> COM causes considerable morbidity with ear discharge, conductive hearing loss and complications. Ossicular reconstruction is a surgical procedure which intends to improve the quality of hearing and life in such patients. Comparison of the outcomes will help to determine the merits or demerits of a particular procedure.</p><p class="abstract"><strong>Methods:</strong> The study was conducted in the Department of ENT, VIMS, Bellary during the period from December 2010 to May 2012. All the patients with CSOM with ossicular erosion suggested by conductive hearing loss more than 40dB were included in the study. A detailed history taking, thorough clinical examination was done for these patients. Before and after the procedure pure tone audiometry was done to assess the hearing outcome. Post operatively PTA was done in 6^th week, 3^rd month, 6^th month follow up. Hearing improvement was analysed according to the type of procedure. The data collected was tabulated and subjected to statistical analysis.  </p><p class="abstract"><strong>Results:</strong> This study compared the outcomes of hearing gain in canal wall up versus canal wall down mastoidectomy surgeries. Hearing gain was better in canal wall up mastoidectomy (18.36 dB) than canal wall down mastoidectomy surgeries.</p><p class="abstract"><strong>Conclusions:</strong> Hearing outcome was better in intact canal wall mastoidectomy than canal wall down mastoidectomy in our study.</p><p class="abstract"> </p>

<p class="abstract"><strong>Background:</strong> Tonsillectomy is one of the major surgical procedure in terms of volume in the oto-rhino-laryngological practice. It is an age old surgical procedure, referred in history of medicine. There have been various changes in the indications and surgical procedures since 4 to 5 decades.</p><p class="abstract"><strong>Methods:</strong> A comparative study between the CO₂laser and conventional method (dissection Hospital set up, by the same surgeon, using two different techniques. The main objective of the study is to compare the intra-operative events (blood loss, time taken for surgery). This study was done in 40 patients undergoing tonsillectomy with or without adenoid hypertrophy removal over a period of 1 year (June 2015– May 2016). The patients (20 cases) in the first half of this period underwent conventional tonsillectomy whereas the rest (20 cases) underwent CO₂laser tonsillectomy. The gathered data were analysed by SPSS software (Ver-25) and using necessary tests. The differences between studied groups less than 0.5 (p&lt;0.05) considered significant statically.  </p><p class="abstract"><strong>Results:</strong> Among 40 patients, 20 cases underwent tonsillectomy by CO2 laser and 20 cases by conventional method. 20 patients who underwent laser tonsillectomy had lesser bleeding (25 ml vs 60 ml) intraoperatively, p&lt;0.05 (significant) and total time consumed during surgery is less (4.5 minutes vs 15 minutes) with laser when compared to conventional method p&lt;0.05 (significant).</p><p class="abstract"><strong>Conclusions:</strong> CO₂laser tonsillectomy is associated with low intraoperative bleeding and less time consuming surgery when compared to conventional tonsillectomy.</p>

<p class="abstract"><strong>Background:</strong> COM causes considerable morbidity with ear discharge, conductive hearing loss and complications. Myringostapediopexy and myringoplationpexyis a surgical procedure which intends improve the hearing and quality of the life.</p><p class="abstract"><strong>Methods:</strong> The  study was conducted in the department of ENT, SMVMCH, Puducherry from April 2017 to April 2018. A detailed history taking thorough clinical examination done for these patients. PTA was done before the procedure, post operatively at 3^rd month. Hearing improvement analysed using different parameters like type of graft used, hearing gain and graft uptake. The data collected was tabulated and subjected to statistical analysis.  </p><p class="abstract"><strong>Results:</strong> Myringostapediopexy better hearing gain than myingoplatinopexy. Myringostapediopexy mean hearing gain 19.53 dB, myringoplatinopexy 12.59 dB.</p><p class="abstract"><strong>Conclusions:</strong> This study compared the hearing outcomes of Myringostapediopexy and myringoplatinopexy with respect to hearing gain. Myringostapediopexy better hearing gain than myringoplatinopexy due to presence of stapes supra-structure.</p>
