Ossiculotympanic transplantation.
Continued investigations into current tympanoplasty problems have been carried out in the Eye and Ear Clinic, Royal Victoria Hospital, Belfast. Retrospective studies have been helpful in identifying some of the main problems responsible for many of our unsatisfactory results, both in the irradication of disease and the restoration of aural function. Prospective studies into the behavior of grafting materials for tympanic reconstruction in the experimental animal have led us to an overwhelming preference for natural materials as opposed to plastics or stainless steel. Both homologous and autologous bone and cartilage appear to offer good prospects in ossicular replacement techniques. The most satisfactory material we have used for repair of tympanic membrane defects continues to be either autologous or homologous temporalis fascia. The long-term success of these materials in functional restoration is utterly dependent on continued aeration of the tubotympanic cleft.
