Abstract
The inherent risk of the labyrinthine damage in middle ear surgery must be clearly understood and seriously considered by an otologist. The present study, conducted on sixty patients, was divided into three groups of twenty each — Group-I (Myringoplasty), Group-II (All types of Mastoidectomy), Group-III (Combined approach tympanoplasty). Bone conduction thresholds in different frequencies were recorded by a pure-tone audiometer both pre-operatively and post-operatively. The over-all results showed one case (1.67%) with significant or severe SNHL of more than 25 dB and ten cases (16.66%) with mild to moderate SNHL including three cases of temporary threshold shift. In majority of the cases (11.67%) 2000 and 4000 frequencies were involved. The possible causes have been analysed in the study.
