    Abstract:
    INTRODUCTION: Jugular bulb and sigmoid sinus anomalies are well-known causes of vascular pulsatile tinnitus. Common anomalies reported in the literature include high-riding and/or dehiscent jugular bulb, and sigmoid sinus dehiscence. However, cases of pulsatile tinnitus due to diverticulosis of the jugular bulb or sigmoid sinus are less commonly encountered, with the best management option yet to be established. In particular, reports on surgical management of pulsatile tinnitus caused by jugular bulb diverticulum have been lacking in the literature. OBJECTIVES: To report two cases of pulsatile tinnitus with jugular bulb and/or sigmoid sinus diverticulum, and their management strategies and outcomes. In this series, we describe the first reported successful case of pulsatile tinnitus due to jugular bulb diverticulum that was surgically-treated. SUBJECTS AND METHODS: Two patients diagnosed with either jugular bulb and/or sigmoid sinus diverticulum, who had presented to the Otolaryngology clinic with pulsatile tinnitus between 2016 and 2017, were studied. Demographic and clinical data were obtained, including their management details and clinical outcomes. RESULTS: Two cases (one with jugular bulb diverticulum and one with both sigmoid sinus and jugular bulb diverticula) underwent surgical intervention, and both had immediate resolution of pulsatile tinnitus post-operatively. This was sustained at subsequent follow-up visits at the outpatient clinic, and there were no major complications encountered for both cases intra- and post-operatively. CONCLUSION: Transmastoid reconstruction/resurfacing of jugular bulb and sigmoid sinus diverticulum with/without obliteration of the diverticulum is a safe and effective approach in the management of bothersome pulsatile tinnitus arising from these causes.
