Penetrating wounds of the ear with oval window fistulas. Reports of 2 cases.
In 2 patients with penetrating wounds of the ear lesions involved the tympanic membrane and the ossicular chain. The long process of the incus was lying on the fallopian canal and the stapes was deeply depressed into the vestibule. In spite of a large oval window fistula, cochleovestibular signs were minimal. The fistula was sealed with adipose tissue and the stapes replaced by a Teflon-platinum piston prosthesis. The incus was repositioned and supported by a fat graft placed between the fallopian canal and the long process. This original technique of reconstructing the ossicular chain gave satisfactory functional results in both patients.
