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.
