Of the 20 ears, hearing loss was moderate in 5 per cent (<jats:italic>n<\/jats:italic>\u00a0=\u00a01), severe in 55 per cent (<jats:italic>n<\/jats:italic>\u00a0=\u00a011) and profound in 40 per cent (<jats:italic>n<\/jats:italic>\u00a0=\u00a08).

Computed tomography scans indicated pervasive abnormalities of the external auditory canal, tympanic membrane, middle-ear space, ossicles, oval window, round window and internal auditory canal. Narrowed internal auditory canals corresponded to poor speech discrimination, indicative of retrocochlear pathology and absent auditory brainstem response waves.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215113002648_sec4\"><jats:title>Conclusion:<\/jats:title><jats:p>Progressive abnormal bone formation in sclerosteosis involves the middle ear, the round and oval windows of the cochlea, and the internal auditory canal.
