MDCT of Dehiscent or Thin Bone Coverage over the Superior Semicircular Canal: Assessment of Prevalence by Age and Contralateral Canal Bone Thickness
Abstract
Objective: Superior semicircular canal dehiscence (SSCD) describes the presence of a defect in the superior bone coverage of the membranous SSC. The etiology of the defect is not known and its reported CT prevalence is variable. This study primarily aimed to report MDCT prevalences of SSCD and thin bone coverage over SSC among different age groups. A secondary aim was to assess for any association between SSCD and the thickness of contralateral bone coverage over SSC.
Materials and Methods: Temporal bone MDCTs were retrospectively evaluated for SSCD and the thickness bone coverage over SSC. The prevalences of SSCD and thin bone coverage over SSC among different age groups, and the thickness of bone over SCC in SSCD and non-SSCD subjects were analyzed.
Results: 509 subjects were included in the study. Age-adjusted models did not demonstrate a significant association between the age groups and the prevalence of SSCD (p=0.63) or between the age groups and the prevalence of thin bone coverage over SSC (p=0,81). Unilateral SSC roof thickness of ≤ 0.5 mm was significantly associated with increased prevalence of contralateral SSCD (p=0.05 and p=0.04). In subjects without radiological evidence of SSCD, right-or left-sided thin bone coverage over SSC was significantly associated with contralateral thin bone coverage (p<0.00).

MDBT’de Defektif ya da İnce Süperior Semisirküler Kanal Kemik Örtüsü: Yaş ve Kontralateral Kanal Kemik Kalınlığına Göre Prevalansın Değerlendirilmesi
Abstract
Amaç: Süperior semirsiküler kanal dehisansı (SSKD), membranöz SSK’yi örten kemikte bir defekt bulunmasını tanımlar. Bu defektin etiyolojisi bilinmemekte olup literatürde bilgisayarlı tomografi (BT) incelemelerinde bildirilen SSKD prevalansları değişkenlik göstermektedir. Bu çalışmada başlıca, multidedektörlü BT’de (MDBT) farklı yaş gruplarındaki hastalarda SSKD ve ince SSK kemik örtüsü prevalanslarının saptanması amaçlanmıştır. Diğer bir amaç ise SSKD ve SSK kemik örtüsünün ince olması ile kontralateral SSK kemik örtüsü kalınlığı arasında bir ilişki bulunup bulunmadığının değerlendirilmesidir.
Gereç ve Yöntem: Temporal kemiğin MDBT incelemeleri SSKD ve SSK kemik örtü kalınlığı açısından retrospektif olarak değerlendirildi. Farklı yaş gruplarındaki hastalar arasında SSKD ve ince SSK kemik örtü prevalansları ile SSKD’si bulunan ve bulunmayan hastalarda SSK kemik örtü kalınlıkları değerlendirildi.
Bulgular: Çalışmaya 509 hastanın temporal MDBT incelemeleri dahil edildi. Yaşa göre modellemeler, farklı yaş gruplarındaki hastalar arasında SSKD ya da ince SSK kemik örtü prevalanslarının anlamlı bir değişim göstermediğini ortaya koydu (p=0.63 ve p=0,81). Bir kulakta SSK kemik çatı kalınlığının 0.5 mm ya da altında olması ile karşı kulakta artmış SSKD prevalansı arasında istatistiksel olarak anlamlı bir ilişki bulundu (p=0.05 ve p=0.04). SSKD’si bulunmayan hastalarda sağ ya da sol kulak SSK kemik çatısındaki incelik ile karşı kulak SSK kemik çatısındaki incelik arasında anlamlı ilişki mevcuttu (p<0.00).
Sonuç: Bu çalışmada artan yaş ile birlikte SSKD ya da ince SSK kemik örtüsü prevalanslarının da artış gösterdiğine dair bir bulgu saptanmadı. Bir kulakta SSKD’si bulunan hastalarda karşı kulaktaki SSK kemik çatı kalınlığı anlamlı olarak düşük bulundu.
