title: Fascia and perichondrium atrophy in tympanoplasty and recurrent middle ear atelectasis.
abstract: Fascia and perichondrium grafts to replace and reinforce thin, atrophic tympanic membranes (TMs) are recommended by several authors to correct middle ear atelectasis by forming a fibrous, collapse-resistant TM. This study reviewed the status of connective tissue grafts performed over the 10-year period from 1979 to 1988 to determine if these grafts would maintain sufficient strength and fibrous character to resist recurrent atelectasis. The author used fascia or perichondrium to repair 89 TM defects, and 63 ears were available for follow-up: 54 had cholesteatomas and 9 had perforations. Graft atrophy was judged by microscopic otoscopy and Kodachrome otophotography. Fascia TM grafts atrophied in 35 of 43 ears (80%), and perichondrium atrophied in 8 of 20 ears (40%). Grafts maintained their relatively thick and fibrous character in only 20 of 63 ears (32%). If fascia and perichondrium used to correct atelectasis were to atrophy at the same rate as the grafts in this series, atelectasis would recur after attempts to reinforce atrophic TMs. Atelectasis-prone middle ears require intubation despite surgery.
