背景:上半规管裂开综合征(SSCD)是由于覆盖上半规管(SSC)的骨丢失而导致的当前诊断。这导致压力/声音诱发的眩晕和示波。
目的:了解中国血统上半规管骨厚度的变化与年龄和性别的关系。
方法:1月到山东大学第二医院耳科门诊就诊的患者的三百十一张颞骨锥束计算机断层扫描(CBCT)图像,2017年4月,2018年进行了回顾性研究。在Poschl线中重建图像,并拍摄覆盖SSC的骨的最薄区域。
结果:我们包括172名(55.31%)女性和139名(44.69%)男性。平均年龄41岁。发现厚度的总体平均差异为-0.0210。女性和男性骨厚度之间没有显着差异(p=0.7113)。年龄的平均差异为0.0801(p=.1557),无统计学意义。
结论:随着年龄的增长,骨厚度没有显著变化。CBCT是评估SSCD的最佳方法。
BACKGROUND: Superior semicircular canal dehiscence syndrome (SSCD) is a current diagnosis that is due to a loss of bone covering the superior semicircular canal (SSC). This results in pressure-/sound- induced vertigo and oscillopsia.
OBJECTIVE: To find the variation of the thickness of the bone that covers the Superior Semicircular Canal with relation to age and gender among the Chinese descents.
METHODS: Three hundred and eleven temporal bone Cone Beam Computed Tomography (CBCT) images of patients who attended Otology clinic at Second Hospital of Shandong University from January, 2017 to April, 2018 were retrospectively studied. The images were reconstructed in the line of Poschl and the thinnest area of the bone covering the SSC was taken.
RESULTS: We included 172 (55.31%) females and 139 (44.69%) males. Mean age was 41 years. Overall mean difference in thickness was found to be -0.0210. There was no significant difference between the female and male bone thickness (p = .7113). With age the mean difference was 0.0801 (p = .1557) which was not statistically significant.
CONCLUSIONS: There was no significant change in bone thickness with advancing age. CBCT is the best method of assessing SSCD.
