Bilateral Conductive Hearing Impairment With Hyperostosis of the Temporal Bone: A New Finding in Robinow Syndrome

Arch Otolaryngol Head Neck Surg. 2012;138(3):309-312. doi:10.1001/archoto.2011.1459

Robinow syndrome (RS) is characterized by hypertelorism, wide palpebral fissures with a short upturned nose, shortening of forearms and forelegs, and genital hypoplasia. The syndrome is classified into dominant (DRS) and recessive (RRS) types, each with distinguishing clinical findings. We evaluated a patient who was diagnosed as having RS with persistent hearing loss. Computed tomographic (CT) images showed ossicular chain changes and thickening of the skull and petrous bones, with appositional bone growth, causing a narrowing of the middle ear cavity and oval and round window niches. These findings were confirmed during an exploratory tympanotomy. To our knowledge, this is the first report of conductive hearing loss in RS.
