Abstract
Choanal atresia (CA) is a congenital nasal airway anomaly that, when present bilaterally, requires urgent surgical intervention. Surgical technique has evolved since its inception with most practices now favoring an endoscopic repair. Restenosis requiring revision surgery is a frequent complication, occurring in as many as 50% of cases. This review aims to highlight the most common surgical approaches, techniques used to prevent restenosis, and newer adjuncts to surgery that may improve outcomes. Bioabsorbable, steroid-eluting stents were first developed for the adult chronic rhinosinusitis population but have been adapted for use in choanal atresia since 2017. The existing literature consists of multiple case series and one case-control study comparing these stents to traditional stents. To date, there have been no reports of restenosis or stent-related complications with these newer products. Choanal atresia remains a difficult surgical pathology for which sustainable surgical results can be challenging. There is reason for optimism in bioabsorbable, steroid-eluting stents as an adjunct to CA repair if future studies expound upon their safety and efficacy.
