Bilateral Choanal Atresia and Endoscopic Surgery: A Chance for CHARGE Patients

Bilateral choanal atresia (CA) is a rare congenital malformation frequently associated with other anomalies. CHARGE association is closely linked to bilateral CA. The aim of this study was to describe the outcomes of the endoscopic repair in bilateral CA, and to assess the role of postoperative nasal stenting in two cohorts of CHARGE-associated and non-syndromic CA. Thirty-nine children were retrospectively analyzed (16 patients had CHARGE-associated CA). The rate of postoperative neochoanal restenosis was 31.3% in the CHARGE population, and 47.8% in the non-syndromic CA cohort. Data on postoperative synechiae and granulation tissue formation, need for endonasal toilette and dilation procedures, and number of procedures per patient were presented. Stent positioning led to a higher number of postoperative dilation procedures per patient in the non-syndromic cohort (p = 0.018), and to a higher rate of restenosis both in the CHARGE-associated, and non-syndromic CA populations. Children with CHARGE-associated and non-syndromic bilateral CA benefitted from endonasal endoscopic CA correction. The postoperative application of an endonasal stent should be carefully evaluated.

Novel Application of Steroid Eluting Stents in Choanal Atresia Repair: A Case Series

PURPOSE

To describe the application of mometasone furoate eluting sinus stent technology in the treatment of choanal atresia (CA) in the hopes of preventing postsurgical stenosis.

METHODS

We analyzed 3 consecutive patients aged 4 days to 16 years undergoing repair of CA at a tertiary pediatric hospital. Mometasone furoate eluting sinus stents were placed intraoperatively. Postoperative need for revision surgery as well as routine surveillance endoscopy were used to determine success of surgery.

RESULTS

Three patients of varying age and etiology underwent successful repair of choanal atresia/stenosis. The steroid eluting sinus stent was deployed successfully in all 3 cases. There was no identifiable restenosis in any of the 3 patients with 12-month follow-up. There were no complications noted throughout the follow-up period.

CONCLUSIONS

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.
