[Experience with the inlaytechnic of tympanoplasties type I. (author's transl)]

After more than ten years of experience with the inlaytechnic of tympanoplasties type I at the ENT-department of the University of Freiburg, and evaluating tha datas of 451 consecutive ears operated between 1970 and 1974, this technic proved to be good. The quote of recidive-surgery was about 19.9%. Hearing improved markedly in 80.4% of the patients. Complications like the appearence of Cholesteatoma, lateral migration of the transplant or flatening of the anterior tympanomeatal angle have not been noticed.
