Venous pulsatile tinnitus (PT) is sound associated with abnormal blood flow near auditory structures in the head, which can impact mental health and may be associated with intracranial hypertension. High-frequency flow instabilities, vortical flow, and regions of high time-averaged wall shear stress (TAWSS) have previously been associated with the sounds of PT, but do not identify potential mechanisms for sound...
This CFD modelling study advances mechanistic understanding of venous pulsatile tinnitus linked to intracranial hypertension, but is not yet translatable to clinical practice; no actionable change for audiologists at this stage.
Clarifying the fluid-mechanical origins of pulsatile tinnitus may eventually guide surgical or interventional treatment planning and improve diagnostic imaging protocols.
