乙状窦憩室临床特征分析

目的　分析8例乙状窦憩室患者的临床特征，提高诊治水平。方法　对耳鸣患者详细询问病史、常规行听力检查（纯音听阈测试、声阻抗测听、耳声发射检查及脑干听觉诱发电位等）、颞骨薄层CT/HRCT平扫，8例患者被诊断为乙状窦憩室。其中6例患者选择行乙状窦憩室还纳填塞术，2例拒绝手术而选择保守治疗。结果　6例患者经 手术证实诊断正确，术中乙状窦沟壁重建后搏动性耳鸣症状消失，随访2～16个月，无复发。2例保守治疗患者症状较前无明显好转。结论　根据临床表现、听力检查、颞骨CT/HRCT、头颅CTA/CTV可诊断乙状窦憩室。乙状窦憩室还纳填塞术是较好治疗方案。

Analysis of clinical characteristics of sigmoid sinus diverticulum

OBJECTIVE To analyze the clinical features of 8 patients with sigmoid sinus diverticulum and to improve the level of diagnosis and treatment. METHODS The tinnitus patients were asked in detail about the history, and performed a series of routine hearing tests (pure tone audiometry, acoustic impedance audiometry, otoacoustic emission inspection and brainstem auditory evoked potential (BAEP) etc.) and temporal bone HRCT scan. Eight cases were diagnosed with sigmoid sinus diverticulum, in which six cases undertook a surgery to reconstruct the sinus wall while the other 2 cases chose conservative treatment. RESULTS The diagnosis of 6 cases was proved to be correct by surgery, and the pulsatile tinnitus disappeared after reconstructing the sinus wall. No one recurred after following up from 2 to 12 months. Two cases of conservative treatment had no obvious improvement in symptoms. CONCLUSION Clinical manifestation, hearing examination, temporal bone CT/HRCT and Cranial CTA/CTV contributed to the diagnosis of sigmoid sinus diverticulum. Sinus wall reconstruction is a better approach.
