Methods: a retrospective multicentric study was conducted between 2010 and 2022. An endonasal endoscopic approach was performed in 38 unilateral or bilateral C.C.A. children. All the patients were clinically and radiologically assessed and followed for at least 2 years. Seven outcome measures were applied. Consequently, surgical success was correlated with all the independent variables reported. Results: 18/38 (47.36%) patients presented normal postoperative healing, 8/38 (21.05) had moderate restenosis (50%), requiring a surgical revision. No statistical significance was found for average hospital stay between stenosis >50% and 50% andenAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/choanal atresiaendoscopic repairlong-term outcomessurgical predictorstransnasal approachChildChoanal AtresiaConstriction, PathologicEndoscopyHumansRecurrenceRetrospective StudiesTreatment Outcomeresearch article35897454open access10.3390/ijerph191590841660-4601PMC9329715https://www.mdpi.com/1660-4601/19/15/9084/pdf?version=1658828533https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9329715/pdf
