[Tympanoplasty using chondro-perichondral graft. Indications, techniques and results. Apropos of a series of 127 cases].

: In an attempt to avoid recurrence, the authors have used chondro-perichondral grafts for more than 10 years for tympanoplasty of retraction pouches. Early results were published in 1987. This new retrospective series of 127 tympanoplasties, performed from 1987 to 1991 reports the anatomic and functional results obtained and the technical modalities used. After a mean follow-up of 18 months, the results appear encouraging. Indications of this chondro-perichondral graft have been widened to cases of unsuccessful first intention myringoplasty and to certain cases of progressive perforations occurring in a setting of inflammation or tubal dysfunction. The results must be confirmed on the basis of long term outcomes.
