To evaluate the usefulness of three-dimensional (3D) helical CT for the detection of abnormalities of the auditory ossicles, 3D helical CT of the middle ear was performed in seven patients with hearing disorder. It revealed that 4 patients had congenital deficiency of the auditory ossicles, 2 patients with chronic otitis media had shortening of the incus and one patient with head injury had doubtful fracture of the incus. This study indicated that 3D helical CT of the middle ear can represent the auditory ossicles objectively and can offer detailed diagnosis.
为评估三维（3D）螺旋CT在检测听小骨异常方面的实用性，对7例听力障碍患者进行了中耳的3D螺旋CT检查。结果显示，4例患者存在听小骨先天性缺失，2例慢性中耳炎患者有砧骨缩短，1例头部受伤患者有可疑的砧骨骨折。本研究表明，中耳的3D螺旋CT能够客观地显示听小骨，并能提供详细的诊断。
