Tympano-ossicular allografts following J. Marquet: the evaluation of a school.

The experience with 1.645 transplantation procedures by ENT surgeons, trained in tympano-ossicular allograft technique following J. Marquet, is reported. The grafts originated from different tissue banks. The anatomical and functional results one year postoperatively were analysed. There appeared to be no statistical differences between tissue banks, nor between surgeons. Contrary to the anatomical results, functional differences existed between allograft tympanoplasties and some types of allograft tympano-ossiculoplasties. It was concluded that the routine use of allograft tympano-ossiculoplasty offers a major tool in otological surgery and that it is the method of choice by the ENT surgeons trained by the School of J. Marquet.
