Abstract
WITH THE advent of microsurgery, an increasing number of middle ear anomalies are being recognized. This case presents congenital deformities of both the stapes and horizontal portion of the facial nerve. This 15-year-old white boy was noted to have a hearing loss in infancy by his parents. He spoke his first words at 16 months. Speech has developed fairly well and intelligibility is fair to good. He began wearing a hearing aid at the age of 6.
