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.
