Novel Application of Steroid Eluting Stents in Choanal Atresia Repair

Abstract

Choanal atresia is a rare disorder that can prove difficult in postsurgical management. In our case series, mometasone furoate eluting stents were effective and safe for the management of this disease process. Further prospective studies are needed to determine the exact safety profile, long-term consequences, and efficacy of steroid eluting sinus stents in the pediatric population.

A rare case report of bilateral choanal atresia in an adult

“…Open trans-palatal techniques have given way to minimally invasive endoscopic repair [7]. The role of a stent is controversial.…”

“…Some investigators advocate its supremacy [8]. Novel application of steroid eluting sinus stent in minimizing scarring following endoscopic repair of choanal atresia with a high level of success [7]. Aksoy et al used mitomycin C after choanoplasty to prevent stenosis [9].…”

Choanal Atresia Repair in Pediatric Patients: Is the Use of Stents Recommended?

“…For example, steroid-eluting stents have shown promising results in the post-surgical maintenance of sinus ostia patency and synechiae prevention in adults [17-18]. Bangiyev et al [19] utilized mometasone furoate steroid-eluting stents (Propel, Intersect ENT, Menlo Park, California, United States) to treat CA in three pediatric patients of age two years, one day, and 16 years, hoping to avoid postsurgical stenosis. The first two cases were identified with bilateral CA whereas the third case exhibited unilateral CA.…”
