摘要
目的探讨基于10μm级耳科专用CT的耳硬化症影像特征。方法回顾性收集2020年10月至2021年7月首都医科大学附属北京友谊医院收治的27例(51侧)耳硬化症患者资料,其中男9例,女18例,年龄22~70(42±12)岁。所有患者均行10μm级耳科专用CT检查及手术治疗。分析耳硬化症的类型、数量及累及部位,评估10μm级耳科专用CT诊断耳硬化症的灵敏度。结果单纯窗型耳硬化症占49.0%(25/51侧),弥漫型占51.0%(26/51侧),未见单纯窗后型。单发病灶占45.1%(23/51侧),多发病灶占54.9%(28/51侧)。前庭窗前区、环韧带受累的发生率为100%(51/51侧),镫骨底板、前庭、耳蜗、圆窗、内听道壁、面神经管、半规管受累的发生率分别为60.8%(31/51侧)、33.3%(17/51侧)、21.6%(11/51侧)17.6%(9/51侧)、13.7%(7/51侧)、9.8%(5/51侧)、7.8%(4/51侧)、5.9%(3/51侧)。该CT仪器诊断耳硬化症的灵敏度为100%。结论10μm级耳科专用CT可全面显示耳硬化症的影像特征,有潜力成为该病的常规检查手段。
Objective To evaluate the imaging features of otosclerosis based on10μm otology CT.Methods Data of 27 patients with otosclerosis(51 sides)in Beijing Friendship Hospital,Capital Medical University from October 2020 to July 2021 were retrospectively collected,including 9 males and 18 females age ffrom 22 to 70(42±12)years.All patients underwent 10μm otology CT examination and surgical treatment.The types,amounts and involved sites of otosclerosis were analyzed and the sensitivity of 10μm otology CT in diagnosing otosclerosis were evaluated.Results Fenestral type accounted for 49.0%(25/51 sides),and diffuse type accounted for 51.0%(26/51 sides),and he retrofenestral type without fenestral lesion was not seen.Single lesions accounted for 45.1%(23/51 sides)and multiple lesions accounted for 54.9%(28/51 sides).The incidence of involvement of the fissula ante fenestram and annular ligaments were both 100%.The incidence of involvement of stapes footplate,vestibule,cochlea,round window,inner auditory canal wall,facial nerve canal,stapes muscle and semicircular canal was 60.8%(31 sides),33.3%(17/51 sides),21.6%(11/51 sides),17.6%(9/51 sides),13.7%(7/51 sides),9.8%(5/51 sides),7.8%(4/51 sides)and 5.9%(3/51 sides),respectively.The sensitivity of 10μm otology CT in diagnosis of otosclerosis was 100%.Conclusion 10μm otology CT can fully display the imaging features of otosclerosis,and has the potential to be an effective routine method for otosclerosis.
