目的:探讨耳蜗性耳硬化症的临床特点。方法:结合文献复习,报告3例2007年3月-2008年10月诊治的经高分辨颞骨CT确认的耳蜗性耳硬化症患者。结果:3例以反复发作性眩晕或(和)平衡障碍为首要主诉,同时有进行性听力下降病史。2例(各1耳)为单纯感音神经性聋,考虑为“纯”耳蜗性耳硬化症,其余为伴不同程度骨导下降的混合性聋。高分辨颞骨CT的特点:耳蜗、前庭、半规管及内耳道等部位可见低密度区,耳蜗区呈现“晕影”征或“双环”征,密度有不均。结论:对不能解释原因的感音神经性聋、存在前庭症状的混合性聋并呈进行性听力下降的慢性病史者应考虑耳蜗性耳硬化症的可能,CT对耳蜗性耳硬化症的临床诊断有重要价值。
Objective: To investigate the clinical features of cochlear otitis media. Methods: According to the literature review, 3 cases of cochlear otitis media confirmed by high resolution temporal CT were treated and treated from March 2007 to October 2008. Results: Three patients were mainly complained of recurrent episodes of vertigo or (or) balance disorder with a history of progressive hearing loss. 2 cases (1 ear) were pure sensorineural deafness, considered as “pure” cochlear otosclerosis, and the rest were mixed hearing loss with varying degrees of bone conduction decline. High-resolution temporal bone CT features: cochlear, vestibular, semicircular canal and internal auditory canal and other parts of the visible low-density area, the cochlear area showing “halo shadow ” sign or “double ring ” sign, the density is uneven. CONCLUSIONS: Cochlear otosclerosis should be considered in patients with sensorineural deafness who can not explain the cause, patients with a combination of deafness presenting with vestibular symptoms and who have a progressive history of hearing loss, and CT in the diagnosis of cochlear ototoxicity Have important value.
