10块防腐人体颞骨标本行横位及岩骨轴位CT扫描，岩骨轴位影像显示迷路后形态较横位影像佳，横位影像能如实反映迷路后形态。分析54名耳部正常者及20名梅尼埃病患者横位CT影像，岩骨迷路后有气房者则其对应之乳突多为高度气化型，其迷路后厚度也较大，但二者与前庭导水管（VA）的显示无确切的关系。两侧岩骨迷路后气化、厚度及VA形态基本对称。耳部正常组中迷路后有气房者占33．3％，迷路后厚度为10．93±2．41mm，VA显示者占63．0％。梅尼埃病组中则分别为13.8％，8.73±2.11mm及44.8％。CT检查的临床意义尚须进一步探讨。
10 anticorrosive human temporal bone specimens horizontal and petrous apexes CT scan, petrous aorta axial images showed that the shape after labyrinth better than horizontal images, transverse images can accurately reflect the shape after the labyrinth. CT images of 54 normal ears and 20 Meniere’s disease patients were analyzed. Most of the corresponding mastoids were hypervaporic and their thickness was greater after labyrinth There is no exact relationship between the two and vestibular aqueduct (VA). Gasification on both sides of the rock bone labyrinth, the thickness and form VA symmetrical. In the normal ear group, there were 33.3% of patients who lost their breath after labyrinth, 10.93 ± 2.41 mm after labyrinthine loss, and 63.0% of those who showed VA. The Meniere’s disease group was 13.8%, 8.73 ± 2.11mm and 44.8% respectively. The clinical significance of CT examination needs to be further explored.
