摘　　要：目的:探讨颞骨高分辨率CT在发现单耳感音神经性聋中的诊疗意义,为合理使用医疗资源提供依据。方法:回顾性分析门诊收集的28例不明时间发现的单耳听力下降的年轻患者病史资料及CT检查结果,并结合相关文献对单耳聋的认识做一综述。结果:研究对象均为单耳重度-极重度的感音神经性聋患者,且外中耳均无异常,颞骨高分辨率CT检查发现9例患者有内耳畸形,阳性发现率为32%,其中单侧的内听道狭窄患者有5例(5/9),单侧共同腔畸形和mondini畸形各1例,前庭与部分半规管融合的畸形2例。19例患者CT检查未发现明显异常,其中4例患者曾有流行性腮腺炎病史。结论:CT检查在发现单耳聋病因方面有一定的意义,可避免患者频繁就医而浪费医疗资源。Objective：To investigate the clinic significance of the temporal bone high-resolution CT in discovering unilateral sensorineural hearing loss of adolescents, and to provide the basis for the rational using of medicalresources. Method：A retrospective study was conducted on 28 outpatients with unilateral sensorineural hearing loss at unsure time. Their medical history and CT examine were reevaluated,combined with associated articles in this report. Result： jail of the 28 patients with unilateral sensorineural hearing loss had the normal external ear and middle ear and received CT scan. Nine out of twenty-eight cases had inner ear malformation. Among the nine cases, 1 cases was Mondini malformation and 1 cases was common cavity, 5 cases were single stenosis of IAC, and 2 cases were semicircular canal and vestibular malformation. 19 cases were not found abnormal by CT, and 4 cases had had suffered from mumps. Conelusion..CT scan was available in diagnosis of unsudden unilateral sensorineural hearing loss, which would help us to use medical resource more rationally.
