Abstract

OBJECTIVE: To identify which patients with advanced otosclerosis may have the greatest audiologic improvement with stapedotomy based on different classifications of advanced otosclerosis.

STUDY DESIGN: Retrospective chart review.

SETTING: Single tertiary neurotology center.

METHODS: Patients were divided into different classifications of advanced otosclerosis based on either a bone conduction threshold of greater than 60 dB HL (Bone Conduction (BC) Group), a word recognition score of less than 70% (Word Recognition (WRS) Group), or pure tone average of greater than 85 dB HL (Pure Tone Average (PTA) Group). Audiologic outcomes and complication profiles were compared between these groups.

RESULTS: Nineteen patients met criteria for one or more group. There were 18 patients in the PTA group, 11 in the BC group, and 12 in the WRS group. There was no significant difference in the pre- or postoperative audiologic status between the different groups.

CONCLUSIONS: Patients with advanced otosclerosis have significant improvements in pure tone averages and air-bone gaps following stapedotomy regardless of the classification criteria used. Stapedotomy remains a reasonable primary intervention for the majority of patients with advanced otosclerosis.
