Temporal bone remodeling after venous stenting for pulsatile tinnitus: isolated dehiscence versus diverticulum

OBJECTIVES: To evaluate clinical outcomes and temporal bone remodeling after venous sinus stenting for pulsatile tinnitus (PT), and to compare remodeling rates between isolated sigmoid sinus wall dehiscence (SSWD) and diverticulum-associated SSWD.

Clinicians managing pulsatile tinnitus with venous sinus stenting should be aware that the type of structural abnormality — isolated dehiscence versus diverticulum — is associated with different rates of post-stenting temporal bone remodeling, which may inform procedural planning and follow-up imaging schedules.

As venous sinus stenting gains traction as a treatment for pulsatile tinnitus, understanding how underlying anatomy shapes bone remodeling outcomes is essential for refining patient selection and post-operative monitoring.
