Objective To describe the safety and efficacy of mometasone furoate-eluting stents in the management
of petrous apex cholesterol granuloma approached through an endonasal endoscopic route
and assess the restenosis rate.
Methods Consecutive patients undergoing endoscopic endonasal marsupialization of a petrous
apex cholesterol granuloma at a tertiary referral center who had a mometasone furoate-eluting
stent placed intraoperatively were reviewed in a retrospective fashion. Postoperative
endoscopy was used to determine success of surgery and stenting.
Results Four patients were included in the study: three were primary cases and one was undergoing
his third revision. The steroid-eluting stent was placed successfully and safely in
all patients with no dural or vascular injury. There was no restenosis in three patients
at 4 months— follow-up. One patient had an immediate restenosis that was debrided
in clinic (revision case) at 1 week postoperatively and was patent at 3 months— follow-up.
Conclusion Mometasone furoate-eluting stent are safe and effective in the primary management
of petrous apex cholesterol granuloma. Further studies are needed to assess their
efficacy in revision cases and for long-term results.
