Pre-operative bone conduction curves in stapedectomy.
Significant post-stapedectomy cochlear deficit is associated with the following factors in an uncomplicated operation: (1) The age of the patient. (2) A pre-operative bone conduction loss, averaged over 0.25, 0.5, 1.0 and 2.0 KHz, of 20 db or more. (3) A left-to-right sloping bone conduction curve (descending audiometric curve), especially where there is a similar curve in the other ear.
