Importance of en bloc homograft in intact canal wall tympanoplasty.

The incidence of cholesteatoma recurrence using intact canal tympanoplasty has been compared in 2 series of operations. The first group represents cases treated with the conventional conservative technique for attic and middle ear surgery. The second group represents cases on which the concept of 'radical attic and middle ear surgery' has been applied and an en bloc homograft has been used for reconstruction. A preliminary survey has shown a much lower incidence of cholesteatoma recurrence in ears belonging to the second group. The advantages of this surgical technique are discussed.
