Treatment of Idiopathic Intracranial Hypertension With Bilateral Trans-stenotic Pressure Gradients: Unilateral Versus Bilateral Venous Sinus Stenting

AND OBJECTIVES: Venous sinus stenting (VSS) is an established treatment for medically refractory idiopathic intracranial hypertension (IIH), yet the clinical significance of bilateral trans-stenotic venous pressure gradients and the optimal stenting strategy in this setting remains poorly defined.

No actionable change for audiologists — this neurosurgical study is only marginally relevant to audiology (IIH can cause pulsatile tinnitus), and clinical decisions remain with neurosurgery.

Optimising venous sinus stenting for IIH has indirect audiology relevance because IIH commonly causes pulsatile tinnitus and hearing symptoms; better neurosurgical management could reduce these referrals.

1. 01Study compares unilateral versus bilateral venous sinus stenting for IIH with bilateral pressure gradients.
2. 02IIH is a known cause of pulsatile tinnitus and pressure-related hearing symptoms.
3. 03Surgical management of IIH falls outside audiologist scope of practice.
4. 04Findings may inform interdisciplinary understanding of tinnitus caused by venous pressure changes.
5. 05Content type is journal article with a direct neurosurgical focus; limited direct audiology application.
