Abstract

Süperior semisirküler kanal dehisansı, ses ile tetiklenen işitme kaybı, vertigo, nistagmus ve osilopsi ile seyreden radyolojik bir tanıdır. Klinik bulgular, kanal üzerindeki kemik yapının bulunmaması nedeniyle gelişen ‘üçüncü pencere’ ile açıklanmaktadır. Bir çalışmada 1000 temporal kemiğin 5’inde bu patoloji bildirilmiştir. Aynı çalışmada bilateral tutulum ise yalnızca bir vakada bildirilmiştir. Bu yazımızda, her iki kulağında uzun yıllardır kulak ağrısı dışında, ek yakınması olmayan, ve bilateral superior semisirküler kanal tutulumu tespit edilen erişkin hasta sunulmaktadır. Bilateral kanal dehisansı nadir görülen bir patolojidir ve bu vakalarda kulak ağrısı beklenmeyen bir semptomdur. Literatür taramamızda benzer bir vakaya rastlanılmamıştır.

Bilateral Superior Semicircular Canal Dehiscence in Patient With Persistent Ear Pain

Abstract

Superior semcircular canal dehiscence is a radiological diagnosis which is associated with sound-induced hearing loss, vertigo, nystagmus and oscillopsia. The clinical manifestations have been explained by the absence of a bony cover, generating a ‘third window’. In one temporal bone survey the prevelance was reported as 5 cases in 1000 temporal bones, whereas, bilateral involvement was observed in one case. Here we present an otherwise healthy adult patient suffering from bilateral persistent ear pain, in whom bilateral superior semicircular canal dehiscence was the sole pathology. Bilateral canal dehiscence is a very rare entity and ear pain is unlikely in these cases. To our knowledge, there has been no similar cases reported in the literature so far.
