PURPOSE: Sigmoid sinus anomalies such as dehiscence or diverticula may present with pulsatile tinnitus (PT) and low-frequency hearing loss. Occasionally, these symptoms are severe, necessitating resurfacing of the affected area to restore a normal-appearing sinus wall. This study describes three cases wherein we managed PT attributed to sigmoid sinus anomalies using polymethylmethacrylate (PMMA) bone cement, a novel material.
METHODS: Three patients with PT without any history of illnesses initially underwent cortical mastoidectomy to expose the affected area and resurface the sinus wall. Subsequently, PMMA bone cement was used to reconstruct any bony defects causing PT symptoms. Viscosity of the bone cement was altered based on specific characteristics and causes of the affected area. Additionally, we performed the water occlusion test (WOT), audiological assessment, the Tinnitus Handicap Inventory score (THI), and temporal computed tomography, both pre- and postoperatively, to assess the extent of PT.
RESULTS: Preoperatively, all three patients had tinnitus that dissipated with pressure on the neck and the water occlusion test (WOT), with no reported vertigo, trauma, or ear infections. Moreover, all three cases had a severe handicap according to the THI. In contrast, all cases had reduced PT and a significantly decreased THI score postoperatively, as well as no recurrence or complications and no instances of increased intracranial hypertension at the 12-month follow-up.
CONCLUSION: All cases showed promising results, emphasizing the sustained benefits of this novel intervention for the management of PT.
