Audiological Outcome of Classical Adenoidectomy versus Endoscopically-Assisted Adenoidectomy using a Microdebrider

Introduction: the aim of this study was to evaluate audiological outcomes following adenoidectomy by the classical method and by endoscopically-assisted adenoidectomy using a powered instrument (microdebrider). materials and methods: this study was conducted in a tertiary care center. it included 40 patients divided into two equal groups of 20 each. group-a patients underwent classical adenoidectomy, while group-b patients were subjected to endoscopically-assisted adenoidectomy using a microdebrider. hearing outcome was measured by post-operative pure-tone audiometry and tympanometry. results: the post-operative average air-bone gap (abg) was reduced from 19.6 db to 11.8 db in group a and from 17.6 db to 8.7 db in group b (p=0.010). there was reversal of tympanometric curves from type-b and type-c to type-a in 55% of the patients in group a, while type-a curve was seen in 90% cases in group b in the post-operative period. conclusion: audiological outcomes of endoscopically-assisted adenoidectomy using a microdebrider were superior compared with classical adenoidectomy.
