Objectives:
To investigate long-term hearing outcomes after ossiculoplasty.
Study Design:
Retrospective study.
Setting:
Tertiary referral center.
Patients:
One hundred ninety-nine patients who underwent ossiculoplasty between 1989 and 2001 by the same surgeon and were followed for more than 5 years.
Methods:
Postoperative hearing outcomes were considered successful if the postoperative air-bone gap was within 20 dB. The outcomes after 6 months and 5 years were analyzed.
Results:
The overall rate of successful outcomes was 61.3% after 6 months and 54.3% after 5 years. There was a significant difference between 6 months and 5 years (p < 0.05). The significant deterioration of long-term hearing outcomes was found in malleus-present ears, ears with cholesteatoma/atelectasis, adults, and ears treated by one-stage operation. The reasons for long-term unsuccessful outcomes were adhesion or retraction of the ear drum in 13 ears (54.2%).
Conclusion:
The hearing outcomes after ossiculoplasty showed significant deterioration on long-term follow-up. Innovative approaches to the management of cholesteatoma/atelectasis are necessary to improve and stabilize long-term hearing outcomes.
