    "abstract": "The primary objective of this case series is to assess the effectiveness of the off-label use of the PROPEL drug-eluting stent, traditionally FDA-approved for sinus surgery, in preventing restenosis following canalplasty in patients with chronic otologic conditions or congenital anomalies. The stent provides both mechanical support to maintain canal patency and localized steroid delivery to reduce inflammation and scarring.\nFour patients with various otologic conditions underwent canalplasty, followed by the placement of drug-eluting stents into the external auditory canal. The stents were inserted to address postoperative stenosis. Clinical outcomes, including ear canal patency, hearing improvement, and the rate of restenosis, were evaluated through regular follow-ups.\nAll patients showed improved ear canal patency, with minimal restenosis observed during follow-up. Hearing improvement was reported in 3 out of 4 patients. The pediatric case exhibited mild medial canal stenosis despite stent placement, but overall improvement was noted. No adverse effects were associated with the stent usage.\nThe off-label use of a drug-eluting stent in canalplasty appears to reduce restenosis rates and maintain canal patency in adults effectively. Further research is warranted to standardize protocols and expand its indications for otologic surgery, particularly in pediatric cases where outcomes may vary.",
