目的：研究儿童外中耳畸形的高分辨率CT(HRCT)表现，为临床诊断和治疗提供准确信息。方法：对临床诊断的外中耳畸形54例（66耳）行HRCT扫描、观察。结果：64耳骨性外耳道闭锁或狭窄；59耳鼓室狭小或闭锁；54耳听骨链发育畸形或缺如；4耳内耳畸形。结论：HRCT能准确显示外中耳畸形的类型、程度，为临床治疗提供重要的参考依据。

Objective:To discuss HRCT features of the congenital deformities of external and middle ear in children so as to provide accurate information for the diagnosis and treatment.Methods:54 cases (66 ears) with deformities of external and middle ear diagnosed clinical y were performed with HRCT. Re-sults:The bone part of the external auditory canal stenosis or atresia occured in 64 ears, tympanic cavity stenosis or obliteration in 59 ears, Ossicle dysplasia or absence in 54 ears, inner ear malformation in 4 ears. Conclusion:HRCT can demonstrate patterns, severity of congenital deformities of external and middle ear accurately, which has already become a indispensable imaging modality for microscopical operation of otology.
