<p class="abstract"><strong>Background:</strong> The objective of the study was to compare the outcome of myringoplasty in dry and wet ears in tubotympanic type of chronic otitis media (COM) with respect to graft uptake and hearing improvement.</p><p class="abstract"><strong>Methods:</strong> This is a prospective study done in department of ENT Bangalore Medical College and Research Institute during the study period of November 2014 to May 2016, wherein a total of 60 patients of tubotympanic type COM with 30 cases each of dry and wet ears, aged 15-60 years were included. The hearing impairment was assessed and recorded by pure tone audiometry (PTA). After obtaining informed written consent the patients underwent myringoplasty (temporalis fascia graft, underlay technique). Microbiological examination of discharge in wet ears was done and histopathology of the excised remnant TM analyzed in both groups. Both groups of patients were followed up for 3 months and assessed for graft uptake and hearing improvement. PTA was repeated at 3 months postoperatively. </p><p class="abstract"><strong>Results:</strong> Our study included 60 patients of tubotympanic type of COM with 30 cases each with dry and wet ears who underwent myringoplasty. Majority of our patients were in second decade in both the groups. There was slight female preponderance in our study with male to female ratio of 0.93:1. Discharge from ears in wet ears was mucoid in consistency and were culture negative. Histopathology of excised remnant TM in wet ears revealed evidence of inflammatory cells and vascularization within stroma of fibroblasts while these were absent in dry ear cases. The overall successful graft uptake following myringoplasty was 88.3% with 86.7% for wet ears and 90% for dry ears with no statistical significance (p value of 0.688>0.05) between the two groups. With respect to hearing improvement post-operatively there was significant hearing improvement in both the groups when compared to preoperative hearing with a mean hearing gain (dB) of 3.43±2.81 in wet ear cases to 3.85±3.05 in dry ear cases, but when compared between the two groups, there was no significant statistical difference (p value of 0.582>0.05).</p><p><strong>Conclusions:</strong> The outcome is equally good for myringoplasty in dry and wet ears in tubotympanic type of chronic otitis media with respect to graft uptake and hearing improvement. </p>
<p class="abstract"><strong>Background:</strong> Determining the cause of conductive hearing loss with an intact tympanic membrane has been a challenge for the otologists for over decades<strong>. </strong>The aim of this study is to ascertain the usefulness of endoscopes to study the various middle ear pathologies on performing endoscopic exploratory tympanotomy.</p><p class="abstract"><strong>Methods:</strong> A retrospective analysis of various pathologies encountered in the middle ear in 88 patients who underwent endoscopic exploratory tympanotomy done over a study period of 3.5 years (January 2015 to June 2018). </p><p class="abstract"><strong>Results:</strong> In our study, age of the patients ranged from 14 to 50 years with a mean age of 32 years. Most common finding on exploration was otosclerosis in 59 patients followed by revision stapedotomy in 12 patients. 5 patients had normal middle ear findings with all ossicles intact and mobile while other pathologies encountered were tympanosclerosis (4.6%), biscuit foot plate (2.3%), mucosal bands (3.4%) and middle ear developmental anomalies (3.4%).</p><p class="abstract"><strong>Conclusions:</strong> On exploring the middle ear<strong> </strong>knowing the various aetiologies helps in better preoperative counseling of the patients for the outcome of surgery. Endoscopic approach for exploratory tympanotomy has the benefit of excellent resolution with higher magnification and wider panoramic view of middle ear anatomy.</p><p> </p>
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.
