    Abstract:
    Reported success rates of endoscopic choanal atresia (CA) surgery vary substantially due to a high heterogeneity in and between study groups. Comprehensive data on the unique patient cohort of newborns with bilateral CA are scarce. Our study aimed to close this gap by using narrow inclusion criteria and standardized surgical outcome parameters. A total of ten neonates who were diagnosed with bilateral complete CA and underwent endoscopic surgery at the Department of Otolaryngology, Head and Neck Surgery in the University Hospital of Munich between 2008 and 2017 were included. Preoperative findings, surgical procedures, outcome, and follow-up were analyzed. Standardized criteria were used to assess surgical outcome. Almost all patients (90%) required at least one revision procedure within the first 6 months after initial surgery because of symptomatic partial or complete restenosis. After that, all surviving patients remained asymptomatic until the end of the follow-up period.Conclusion: Endoscopic bilateral CA repair in neonates is a safe procedure with a high long-term success rate. However, compared to other patient groups with choanal obstruction, restenosis occurs frequently, and revision procedures are required in a large number of cases. This should be considered during preoperative planning and parent counseling. What is Known: • Bilateral complete choanal atresia (CA) is a neonatal emergency that requires surgical intervention. • Reported success rates of endoscopic choanal obstruction repair are highly variable and mostly derived from heterogenous study groups that do not reflect the situation in neonates adequately. What is New: • This study focuses exclusively on newborns with complete bilateral CA who underwent endoscopic surgery within the first 28 days of life and uses standardized criteria to assess outcome. • The long-term success rate of endoscopic bilateral CA repair in neonates is high; however, almost all patients require at least one revision procedure within the first 6 months.
