Management of Sigmoid Sinus Associated Pulsatile Tinnitus: A Systematic Review of the Literature.
Although studies demonstrate 4 to 20% of patients with pulsatile tinnitus (PT) have associated sigmoid sinus anomalies, no consensus exists regarding optimal management. Our objective was to perform a systematic review exploring surgical and endovascular intervention of PT caused by sigmoid sinus anomalies. ⋯ PT as a result of sigmoid sinus diverticula, aneurysms, and dehiscence is a rare, but largely treatable condition. Available interventions include SSW R/R, endovascular intervention, and cardiac U-clip techniques. In SSW R/R, bone pate, unspecified soft-tissue graft, and bone cement had the highest rates of PT resolution. While temporalis fascia and autologous bone chips were the materials most commonly used, they had significantly lower rates of PT resolution compared with the other materials, with the exception of auricular cartilage and bone cement. Most episodes of recurrence are resolved with medical management or a revision procedure. This study serves to summarize the current state of knowledge on the treatment of pulsatile tinnitus across disciplines.
