摘要
目的:分析先天性外中耳畸形的各种CT特征。材料与方法:对高分辨率CT确诊为外中耳畸形的333例404耳的病变部位和类型进行分析。结果:404耳中364耳外耳道闭锁,40耳外耳道狭窄,377耳有听小骨畸形,382耳鼓室狭窄,333耳面神经管乳突段前位。结论:颞骨高分辨CT可获得外、中、内耳畸形类型的影像资料,可为临床制定治疗方案提供依据。
Purpose: To analyze the different CT findings of congenital malformations of the external and middle ear. Materials and methods: 333 cases including 404 ears with external and middle ear malformations diagnosed by high resolution CT (HRCT) were analysed according to the location and type of the malformation. Results: In 404 ears, there were 364 ears with atresia of external auditory meatus, 40 ears with stenosis of external auditory meatus, 377 ears with malformation of the ossicles, 382 ears with stenosis of tympanum and 333 ears with anterior position of the mastoid segment of the facial canal. Conclusion: HRCT can show the location and type of external and middle ear malformation and provide valuable information for surgery.
