Abstract

The aim of the study was to evaluate and compare the efficacy of Endoscopic Adenoidectomy with Microdebrider over Conventional technique by Curettage using Impedance Audiometry findings. In this prospective, randomised, comparative study patients were divided into two groups to undergo one of the above adenoidectomy surgeries. Patients with symptoms of Adenoid hypertrophy after failed maximal medical therapy (12 weeks) were selected after due consideration of the inclusion and exclusion criteria. Baseline Impedance Audiometric assessment was done one week prior to surgery which was compared to Impedance Audiometric values 12 weeks post operatively in each group. This study enrolled 50 patients with adenoid hypertrophy, 25 patients of group A underwent Conventional adenoidectomy and the other 25 patients of group B underwent Endoscopic Adenoidectomy with Microdebrider. Significant difference in type of tympanogram before and after adenoidectomy was found in both the groups (p = 0.0008 in group A & p < 0.0001 in group B). In Group A Percentage of abnormal tympanograms becoming normal (Type A), 12 weeks after adenoidectomy was 80%. In Group B Percentage of abnormal tympanograms becoming normal (Type A), 12 weeks after adenoidectomy was 88%. A statistically significant improvement (p < 0.0001 in both the groups) in the percentage of ears with absent stapedial reflex was observed in both groups postoperatively, with no difference between the two groups suggestive of improvement in eustachian tube function. Association of Preoperatively & Postoperatively Eustachian tube function in each group undergoing adenoidectomy was statistically significant (p < 0.0001). Both forms of adenoidectomy are effective in managing adenoid hypertrophy with tubal dysfunction causing mild conductive hearing loss and prone for OME. However, the audiological and endoscopic evaluation seems to favor Endoscopic Adenoidectomy with microdebrider over conventional adenoidectomy, and it should be therefore considered in the therapeutic management of young patients with adenoidal disease.
