[Our experience with reconstructive surgery++ of the middle ear in tympanoplasties with mastoidectomy]

Abstract

In our department, we studied 243 patients who underwent open or close tympanoplasty, from 1984 to 1989, generally caused by cholesteatoma (229 cases) or by non-cholesteatomatous chronic suppurative otitis media (14 cases). Extrusion of the prosthesis occurred in 15 (11.11%) of a total of 136 cases after an average time of 12.46 months during a 4 to 8 years evolution period. From these cases 5 out of 59 were made with plastipore Porp (8.47%) and 10 out of 76 with plastipore Torp (13.15%). autologous ossicles did not extrude in any case. In the cases of cholesteatoma, open (62.7%) and close (37.3%) techniques were performed, and after above mentioned period of evolution, recidivism of cholesteatoma occurred in 4.11% of patients.
