Abstract
A new operative procedure for the anatomical and functional restoration of both the middle ear and mastoid is described. The technique employs homograft tympanic membrane with ossicles en bloc for the middle ear reconstruction and a homograft dura form and autogenous bone paté is used to recreate the bony posterior ear canal wall. The reconstructed wall becomes hard viable bone in about one year. Results in terms of wall integrity, tympanic membrane survival and hearing are discussed. The mechanism of new bone formation is discussed with presentation of histologic findings.
