摘要
目的 评估结核性中耳炎(TOM)的HRCT特征。方法 回顾性收集经病理证实的TOM病人22例(24耳),其中男8例(36.4%),女14例(63.6%)。分析其临床资料以及HRCT上颞骨气化程度、软组织分布及骨质特点。结果 24耳中,以气化型多见(21耳,87.5%)。中耳软组织表现以完全充满气房(19耳,82.6%)、鼓室(21耳,87.5%)、乳突窦(23耳,95.8%)多见;多数堵塞咽鼓管鼓室口(22耳,91.7%),并可见突入或延伸至外耳道(21耳,87.5%)。蜂房间隔增厚(20耳,86.9%)或模糊多见(17耳,73.9%);骨质破坏也不少见(11耳,45.8%),表现为蜂房间隔中断(7耳,30.4%)、乳突骨皮质破坏(2耳,8.3%)、听骨链破坏(3耳,12.5%)、盾板破坏(2耳,8.3%)、外耳道壁破坏(1耳,4.2%)以及死骨形成(1耳,4.2%)。结论 TOM病人颞骨气化程度好,中耳软组织分布广且易累及咽鼓管和外耳道,蜂房间隔增厚模糊,部分可见骨质破坏。
Objective To evaluate the high-resolution CT(HRCT)features of tuberculous otitis media(TOM).Methods A retrospective analysis was conducted on 22 patients(24 ears)with TOM,confirmed by pathology,including 8 males(36.4%)and 14 females(63.6%).The clinical data and HRCT findings were reviewed,focusing on the degree of pneumatization of the temporal bone,distribution of soft tissue,and bone involvement.Results Among the 24 ears,the pneumatized type was most common(21 ears,87.5%).Soft tissue involvement in the middle ear was most frequently observed as complete filling of the air cells(19 ears,82.6%),tympanic cavity(21 ears,87.5%),and mastoid antrum(23 ears,95.8%).Most cases showed obstruction of the eustachian tube opening(22 ears,91.7%),with protrusion or extension into the external ear canal in 21 ears(87.5%).Thickening(20 ears,86.9%)or blurring(17 ears,73.9%)of the septa between the air cells was commonly seen.Bone destruction was also frequently observed(11 ears,45.8%),including interruption of the air cell septa(7 ears,30.4%),destruction of the cortical bone of the mastoid(2 ears,8.3%),ossicular chain destruction(3 ears,12.5%),destruction of the bony plate(2 ears,8.3%),external auditory canal wall damage(1 ear,4.2%),and sequestrum formation(1 ear,4.2%).Conclusion In TOM patients,the temporal bone typically exhibits good pneumatization.Soft tissue involvement in the middle ear is extensive,frequently affecting the eustachian tube and external auditory canal.Thickening or blurring of the air cell septa is common,and bone destruction may occur in some cases.
