Sigmoid sinus diverticulum drives bone remodeling after stenting for pulsatile tinnitus

After venous sinus stenting for pulsatile tinnitus, temporal bone remodeling occurred in 73.1% of patients with follow-up CT (38/52). Remodeling was significantly more likely with a diverticulum vs isolated wall dehiscence (85.7% vs 47.1%; adjusted OR 8.08, 95% CI 1.31-49.73), a…

• Retrospective single-center cohort of 70 patients; short-term clinical success was 92.9% (65/70) at 3 months.
• Long-term clinical success trended higher in remodelers (97.4% vs 85.7%) but did not reach statistical significance (p=0.15).
• Limitation: 52 of 70 patients had follow-up CT, introducing potential selection bias; single-center design limits generalizability.
