Concern about the possible risk of viral infection being transmitted by the use of homografts has renewed interest in cortical bone autografts as an ossicular substitute. Over the last four years I have used cortical bone on a regular basis. Comparison of hearing results obtained using ossicular and cortical bone grafts shows no significant difference between the two groups. Cortical bone appears to be satisfactory material for ossiculoplasty, but long-term studies of outcome are required to confirm this.
