Bilateral Koklear Otoskleroz: Klinik ve Radyolojik Bulgular

Bu raporda, 41 yaşında, sağ kulağında tek taraflı mikst tip işitme kaybı olan bir kadın hastayı sunduk. Hasta daha önce bir trafik kazası geçirmişti; ancak kulak enfeksiyonu öyküsü yoktu. Yüksek çözünürlüklü bilgisayarlı tomografi iki taraflı koklear otoskleroz olduğunu gösterdi, ama kemikçik dislokasyonu bulgusu saptanmadı. Koklear otosklerozun sağ kulakta otik kapsül lateral duvarını tutarak mikst tip işitme kaybına, sol kulakta ise sensörinöral işitme kaybına yol açtığı düşünülmüştür. Hastanın sağ kulağında koklear otoskleroz ile fenestral otosklerozun insidental olarak bir devamlılık arz ettiğini ve işitme kaybı vakalarında eşlik eden olası patolojilerin ortaya konması için radyolojik incelemenin önemli olduğunu düşünmekteyiz.

Bilateral Cochlear Otosclerosis: Clinical and Radiological Findings

In this report, we presented a 41-year-old female patient with unilateral hearing loss inthe right ear. Previously she had a traffic accident, but had no history of ear infection.High resolution computed tomography revealed bilateral cochlear otosclerosis, with noevidence of ossicle dislocation. It was thought that cochlear otosclerosis caused mixedtype hearing loss in the right ear by involving the lateral wall of the otic capsule and sensorineural hearing loss in the left ear. We think that fenestral and cochlear type otosclerosisincidentally occurred along a continuum in the right ear of the patient, and that radiological investigation is crucial in clarifying the possible concomitant pathologies in cases ofhearing loss.
