摘要
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。
High resolution CT scans were carried out in transverse and axioarpetrosal plane on 10 preserved specimens of human temporal bone. The retrolabyrinthine morphology of petrous bone was visualized better in axio-petrosal plane, and the morphology was illustrated accllrately in transeverse plane. The transverse CT images of 54 people with normal ear and 20 patients with Meniere's disease were analyzed. Well pneumatized mastold and large retrolabyrinthine thickness were found in the majority of the images when air cells were discovered in the retrolabyrinthine part of the petrous bone, but there was no definite relation betWeen those and the visualization of the vestlbular aqueduct. A high degree of symmetry of retroiabyrinthine pneumatization and thickness, and vestibular aqueduct was found. In the normal ear group, 33. 3% were found to have retrolabyrinthine air cells, 63. 0% had their vestibular aqueduct demostrated, the retrolabyrinthine thickness was 10. 93 ± 2. 41mm. In the Meniere's disease group, 13. 8% had retrolabyrinthine air cells, 44. 8% demonstrated vestibular aqueduct, and the retrolabyrinthine thickness was 8. 73± 2. 11mm. The clinical significance of CT examinationneeds further invetigation.
