Abstract

Objective

To evaluate the incidence of stapedectomy patients who developed significant chronic ear disease resulting in reconstruction of the tympanic membrane with cartilage and concomitant revision stapedectomy. Audiometric results of this subgroup within revision stapedectomy are analyzed, and the salient features of the reconstruction method are discussed.

Study Design

Retrospective study of revision stapedectomy patients during the years 2003–2012.

Setting

Tertiary referral center.

Intervention

Cartilage tympanoplasty and revision stapedectomy.

Results

Seventeen patients (18 ears) of 144 revision stapes patients were studied who required cartilage tympanoplasty and revision stapedectomy. One-half underwent revision stapedectomy with a modified Lippy prosthesis (MLP), and one-half required a total ossicular prosthesis (TOP). The mean postoperative air-bone gap (ABG) was 11.1 dB with mean pure tone average (PTA) hearing improvement of 15.6 dB.

The rate of ABG closure was 55.6% <10 dB and 38.8 % >10 dB and <20 dB.

Conclusion

The number of patients requiring revision stapedectomy due to significant chronic ear disease is small. This paper discusses the management and successful outcome of these more difficult revisions.
