title: Symposium: Methods of reconstruction in tympanoplasty. IV. Conchal perichondrium as a tympanic graft with maintenance of drum conization.
abstract: Tympanoplasty reconstruction of the eardrum approached normal anatomy and function with the use of connective tissue to replace the substantia media. Perichondrium taken from the concha is preferred because it lies flat and is easy to manipulate. Grafts placed on the outer surface of the remnant tend to lateralize with loss of drum conization. Grafts placed on the undersurface of the remnant do not have this disadvantage.
