Cholesteatoma is a common disease of the middle ear cleft associated with several complications, Surgery is the mainstay for the management of such a pathological condition, however, complications may occur including intracranial ones due to violation of middle cranial fossa dura. Anatomical variations have been reported and High-resolution CT scan is the major tool for detecting such variations. In this study, we aim to determine if there is a difference between tegmen height between both sides of patients with unilateral cholesteatoma. 21 patients were recruited for such study all underwent HRCT and the tegmen height was determined in two coronal planes, the first between the central point of the Henle spine and the tegmen, the other between the plane of both lateral canals and the roof of the middle ear. The tegmen height measurements showed that the affected side had significantly lower tegmen height Henle spine (6.30 ± 1.54 vs. 9.03 ± 1.34 (mm); < 0.001) relative to the healthy side. Also, coronal plane measurement has shown statistical significance for tegmen height (2.98 ± 0.79 vs. 4.15 ± 0.76 (mm); = 0.01) in comparison to the healthy side. The percentage of difference between both sides as regards tegmen height of Henle's spine and coronal measurement was 30.32% and 28.2%, respectively. A significant difference was found in tegmen height between healthy and diseased sides in patients with unilateral cholesteatoma.
胆脂瘤是中耳裂的常见疾病，伴有多种并发症。手术是治疗这种病理状况的主要手段，然而，可能会出现并发症，包括由于侵犯中颅窝硬脑膜而导致的颅内并发症。已有解剖变异的报道，高分辨率CT扫描是检测此类变异的主要工具。在本研究中，我们旨在确定单侧胆脂瘤患者两侧的鼓室盖高度是否存在差异。招募了21例患者进行此项研究，所有患者均接受了高分辨率CT检查，并在两个冠状平面上确定鼓室盖高度，第一个平面位于锤骨嵴中心点与鼓室盖之间，另一个平面位于双侧半规管平面与中耳顶之间。鼓室盖高度测量结果显示，患侧相对于健侧，鼓室盖高度在锤骨嵴处显著更低（6.30±1.54 vs. 9.03±1.34（mm）；P<0.001）。此外，与健侧相比，冠状平面测量的鼓室盖高度也具有统计学意义（2.98±0.79 vs. 4.15±0.76（mm）；P = 0.01）。锤骨嵴鼓室盖高度和冠状测量两侧之间的差异百分比分别为30.32%和28.2%。单侧胆脂瘤患者健侧和患侧的鼓室盖高度存在显著差异。
