Clipping of sigmoid sinus diverticulum: how I do it.

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.
