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.
