MATERIALS AND METHODS
This was a prospective study which was conducted among 50 patients of age group 5 to 14 years over two year period Subjects were diagnosed cases of adenoid hypertrophy divided in two study groups of 25 each. In each group, preoperative assessment of middle ear function was done using pure tone audiometry and tympanometry for all the patients. Group 1 patients were treated by a transoral approach with conventional curettage adenoidectomy using St. Clair Thomson’s adenoid curette and group 2 patients were treated by endoscopic microdebrider assisted approach, both the nasal cavities were packed with cotton pledgets soaked with 2% lignocaine and adrenaline for fifteen minutes. Following removal of the pledgets, a 4mm Storz rigid nasal endoscope was passed through the nasal cavities to visualize the nasopharynx and the adenoid tissue was removed under direct vision using microdebrider. Post operatively patients were called for two follow up visits, first visit after 1 month and second visit after 2 months of performing the procedure. Repeat pure tone audiometry and tympanometry were conducted at both the follow up visits. All the cases of adenoid hypertrophy which were diagnosed clinically and confirmed by x-ray examination were included for the study. Conditions mimicking adenoid hypertrophy clinically like angiofibroma, nasal Polyposis, nasopharyngeal carcinoma and gross DNS were excluded from the study. Pre and post operative pure tone and impedence audiometric parameters were compared. Statistical analysis of the data was done by using ANOVA (Fischer F test)and student’s unpaired T test. A statisiscal package, SPSS 17 was used for analysis. A p value of less than 0.05 was considered significant.
