Hearing loss in Noonan syndrome

Int J Pediatr Otorhinolaryngol. 1992 Jan;23(1):81-4. doi: 10.1016/0165-5876(92)90082-z.

Abstract

A report is presented on a man of Turkish origin, with Noonan Syndrome and unilateral conductive hearing loss since early childhood. There was no history of otitis media. At the age of 23, exploratory tympanotomy revealed a total absence of the long process of the incus and a normal-looking tympanic membrane. The position of the normal-shaped mobile stapes was just medial, and not posteromedial, to the malleus. A congenital ossicular chain anomaly was diagnosed. An allograft malleus head was interposed between the stapes and the malleus. The resulting air-bone gap was less than 10 dB. A review of the literature is given on hearing loss in Noonan Syndrome.
