Osteopetrosis of the temporal bone.
Osteopetrosis is a rare hereditary disorder of bone development. We examined the right temporal bone of a 17-year-old boy with recessive osteopetrosis and a conductive hearing loss and describe the histopathologic characteristics. The conductive deafness in this case was caused primarily by recurrent otitis media.
