Does bilateral otosclerosis make pre-operative bone conduction more inaccurate?

To assess whether bilateral otosclerosis renders pre-operative bone conduction more inaccurate by increasing the Carhart effect. Retrospective review of a database of pre and post-operative audiograms of 745 ears with otosclerosis treated with stapedectomy from 2013 to 2020 in a tertiary centre. Cha...

Description
Summary:To assess whether bilateral otosclerosis renders pre-operative bone conduction more inaccurate by increasing the Carhart effect. Retrospective review of a database of pre and post-operative audiograms of 745 ears with otosclerosis treated with stapedectomy from 2013 to 2020 in a tertiary centre. Change in bone conduction after stapedectomy for otosclerosis in: unilateral otosclerosis (U1); bilateral otosclerosis undergoing first side surgery (B1); bilateral otosclerosis undergoing second side surgery (B2). The magnitude of change in bone conduction post-operatively within and between each group. The average difference in pre and post-operative bone conduction was significant within in all groups (T-stat > 2 and P-value
