Abstract: 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.
