Objective: To report two cases of transmastoid clipping of a sigmoid sinus diverticulum.
Methods: Two patients with pulsatile tinnitus resulting from a sigmoid sinus diverticulum underwent clipping at the diverticulum neck using intra-operative Doppler ultrasonography.
Results: At six months' follow up, both patients reported complete resolution of pulsatile tinnitus with no complications.
Conclusion: Transmastoid clipping of a sigmoid sinus diverticulum can be a safe and effective method of managing pulsatile tinnitus resulting from a sigmoid sinus diverticulum.
