[Tympano-ossicular homografts].

Following a few European and American authors, we have undertaken tympano-ossicular homografts at the Hotel-Dieu de Quebec. The organization of the bank was achieved with many difficulties. We undertook our first surgical homografts in 1974, and 27 cases have since been performed. Our statistics are based on 19 cases. We obtained a perfect tympanic membrane in 17 cases, and 60 per cent of these have shown good improvement in hearing. This percentage is remarkable when one considers that we limited this procedure to cases for which all other techniques were bound to fail.
