Abstract

Craniometaphysial dysplasia is a rare cause of conductive hearing loss. It is a genetic disorder of bone due to decreased osteoclastic activity inthe endosteal and periosteal regions of craniofacial and long bones. The characteristic temporal bone abnormalities are attic fixation, abnormallyshaped ossicles and obliterated foramina ovale. Computerised tomography is helpful in predicting operative findings; surgery should be reserved for those with a severe hearing loss.
