Cartilage tympanoplasty for management of retraction pockets and cholesteatomas.

Abstract

Retraction pockets of the tympanic membrane, often associated with dysfunction of the eustachian tube, can be destructive, leading to loss of hearing, ossicular erosion, and development of cholesteatomas. This retrospective study reviews results from 35 patients (38 ears) operated on from January 1988 to June 1991 whose composite cartilage-perichondrial grafts harvested from the tragus were used to reconstruct the tympanic membrane. Early grafts reinforcing the posterosuperior quadrant of the pars tensa showed some failures, with recurrent retraction in the attic. In later grafts, additional placing of cartilage under the pars flaccida prevented failures in the attic. Our indications, initial technique and refinements to the present form, and hearing results are discussed.
