Abstract
Objective This study describes the safety and efficacy of mometasone furoate eluting stents
in the management of petrous apex cholesterol granuloma approached through an endonasal
endoscopic route and assesses 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 Five patients were included in the study, three were primary cases and two patients
had revision surgeries performed. The steroid eluting stent was placed successfully
and safely in all patients with no dural or vascular injuries. The average follow-up
duration was 10.6 months. There was no restenosis in three patients and one patient
had an immediate restenosis that was debrided in clinic (revision case). This was
patent at the 16 months follow-up. One patient also developed stenosis, 4 months after
surgery due to sphenoid sinusitis.
Conclusion Mometasone furoate eluting stents 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.
