Abstract Background Microdebrider has superior efficacy in clearing the adenoids, compared to curettage. We compared the improvement in middle ear function and hearing thresholds after adenoidectomy, by both methods. Materials and methods 126 patients (median age—9 years) were randomized into groups A and B, where adenoidectomy was done by microdebrider and curettage, respectively. Middle ear function parameters and hearing thresholds were measured serially. Results The mean improvement in middle ear pressure, compliance and hearing thresholds were 92.5 ± 67.6 and 84.2 ± 71.4 daPa; (p = 0.40), 0.19 ± 0.34 and 0.27 ± 0.27 mL; (p = 0.07) and 3.20 ± 4.95 and 2.54 ± 3.98 dB; (p = 0.27), in groups A and B, respectively. Reversal of type B tympanograms was noted in both groups. Conclusions Middle ear function and hearing thresholds improved in both groups after adenoidectomy. More improvement was noted in the microdebrider group, which, however, was not significant. Keywords Adenoidectomy · Acoustic impedance tests · Audiometry · Middle ear
Introduction Adenoid hypertrophy predisposes children to middle ear pathology, which can adversely affect hearing. The primary goal of adenoidectomy is the resolution of symptoms of nose and ear, and the secondary goal is to prevent the development of adenoid facies. Adenoidectomy hastens the resolution of otitis media with effusion (OME) and restores normal middle ear function [1–3].

using adenoidectomy curettes. Being a blind procedure, it gives less exposure and less favourable outcomes. With the developments in fibre-optics and endoscopic instrumentation, alternate methods have been devised, which are gaining popularity despite increased costs. The use of a microdebrider, along with a nasal or oral endoscope, has been shown to remove adenoid tissue more precisely and safely [4]. Obstruction of the eustachian tube opening by the hypertrophied adenoids is one of the proposed reasons for recurrent middle ear pathology like otitis media with effusion and subsequent hearing impairment. Conventional adenoid
