Amaç: Temporal kemik Bilgisayarlı Tomografi‘de (BT) otoskleroz bulguları olan hastalarda süperior semisirküler kanal dehissansı(SSKD) sıklığını araştırmaktır.
Yöntem: Temporal kemik BT’de otoskleroz bulgusu olan 43 (22 erkek, 21 kadın; ortalama yaş,44 ±11 yıl; dağılım, 20-71 yıl) hastanın 86 temporal kemik BT görüntüsü retrospektif olarak değerlendirildi. Bu BT görüntülerinde fenestral / retrofenestral tip otoskleroz bulgularının ve süperior semisirküler kanal dehissansının sıklıkları, yaş ve işitme kaybı tipleri ile karşılaştırılarak değerlendirildi .
Bulgular: 80 temporal kemikte fenestral tip (n:73, %84,8) ve retrofenestral tip (n:7, %8,1) otoskleroz tespit edildi. 86 temporal kemiğin 11‘inde (%12,7) SSKD bulundu. Fenestral tip otoskleroz bulgusu tespit edilen 11 temporal kemikte eş zamanlı SSKD izlendi (p=0.203). Retrofenestral tip otoskleroza sahip hastalar ile SSKD arasında istatistiksel olarak anlamlı farklılık saptanmadı(p=0.588). 86 temporal kemikte 20-40 yaş grupta, 40 yaş üstü gruba göre SSKD sıklığı anlamlı olarak fazla bulundu (p=0,001).
Sonuç: Bu çalışmada otosklerozda SSKD sıklığı %12,7 bulunmuş olup birlikteliğin sıklığının bilinmesi, otoskleroz nedeniyle opere olacak hastalarda yüksek çözünürlüklü temporal kemik BT’nin önemini arttırmaktadır.

Investigation of the frequency of superior semicircular canal dehiscence in patients with otosclerosis

Abstract
Purpose: To investigate the frequency of superior semicircular canal dehiscence (SSCD) in patients with signs of otosclerosis on temporal bone computed tomography (CT).
Materials and Methods: 86 temporal bone CT images of 43 patients (22 men, 21 women; mean age,44 ±11 years; distribution, 20-71 years) with otosclerosis were retrospectively evaluated in Temporal bone CT. In these CT images, the frequency of fenestral / retrofenestral type otosclerosis findings and superior semicircular canal dehissance were compared with age and types of hearing loss .
Results: Fenestral type (n:73, 84.8%) and retrofenestral type (n:7, 8.1%) otosclerosis were detected in 80 temporal bones. SSCD was found in 11 (12.7%) of 86 temporal bones. SSCD was detected in 11 temporal bones with signs of Fenestral type otosclerosis (p=0.203). There were no statistically significant differences between SSCD and patients with retrofenestral type otosclerosis(p=0.588). 86 temporal bones were evaluated, the frequency of superior semicircular canal dehissance was significantly higher in the 20-40 age group than in the 40-year-old group (p=0.001).
Conclusion: In this study, the frequency of SSCD in otosclerosis was found to be 12.7% and knowing the frequency of association increases the importance of pre-operative high-resolution temporal bone CT, especially in patients who will be operated due to otosclerosis.
