Allograft tympanoplasty type 1 in the childhood population

Abstract

Seventy allograft type 1 tympanoplasties in children under 16 years of age were studied retrospectively. Only patients with a tympanic membrane perforation without cholesteatoma and a normal ossicular chain were included. Short-term and long-term anatomic and functional results were analyzed after a mean follow-up of 40 months. The overall short-term take rate was 97% and the long-term take rate was 88%. A number of variables with alleged prognostic value for surgical outcome were analyzed, but none showed statistical correlation with either anatomic or functional results. A median hearing gain of 10 dB was achieved, which was stable over time. We conclude that allograft tympanoplasty type 1 in this group of children is anatomically and functionally successful regardless of age.
