Abstract Background: If the pulsatile tinnitus caused by sigmoid sinus diverticulum/dehiscence cannot be diagnosed and treated, it can lead to significant morbidity and mortality. Aim: To assess the sandwich surgical technique for sigmoid sinus wall reconstruction for the treatment of pulsatile tinnitus caused by sigmoid sinus diverticulum/dehiscence. Methods: A chart review was conducted with 17 patients suffering from pulsatile tinnitus caused by sigmoid sinus diverticulum/dehiscence who underwent sinus wall reconstruction surgery between January 2014 and July 2019. Results: Of the total patients studied, 16 were female, and one was male. The procedure was performed on the right ear of 15 patients and on the left ear of 2 patients. The pulsatile tinnitus disappeared in all patients following the sinus wall reconstruction surgery using the sandwich technique. The mean follow-up time was 25 months (a range of 8-55 months). In the follow-up period, no recurrence of pulsatile tinnitus was found. None of the patients experienced major complications such as thrombosis. Conclusions: The sandwich surgical technique for sinus wall reconstruction as a treatment for pulsatile tinnitus caused by sigmoid sinus diverticulum is safe and effective.
