Role of autografts in the reconstruction of ossicular chain in intact canal wall procedures

摘要

Abstract Improvement of hearing in ossiculoplasty depends on the efficiency of the methods to reestablish the ossicular continuity and the connection with the tympanic membrane. While various prostheses have been used to bridge the ossieular defect, we have used autogenous bone (incus remnant cortical bone ) and autogenous cartilage (frugal conchal) for reconstruction of ossicular continuity.Hearing results at I8 months follow up have been fairly good i.e., 84 patients had closure of air bone gap within 20 dB and 37 had closure of air bone gap within 10 dB.
