Balanced transverse sinus dominance on pre-stent imaging linked to zero residual tinnitus after venous sinus stenting

Among 58 patients undergoing venous sinus stenting for pulsatile tinnitus, balanced transverse sinus dominance on CTV/MRV was associated with 0% residual tinnitus, vs 23.7% unfavorable outcomes with non-balanced dominance (p=0.021).

• After adjustment, non-balanced dominance remained an independent risk factor for unfavorable outcome, while trans-stenotic pressure gradients did not.
• Greater absolute reduction in tinnitus severity was independently associated with higher preoperative tinnitus handicap inventory score (p<0.001) and female sex (p=0.045).
