Abstract
OBJECTIVES: To evaluate immediate versus delayed surgical intervention on treatment outcomes in the management of congenital choanal atresia. METHODS: This study adhered to Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines in reporting a systematic review of the literature. OVID Medline, EMBASE and Pubmed databases were searched using relevant key terms. Inclusion and exclusion criteria were designed to capture studies examining immediate versus delayed primary surgery for congenital choanal atresia. Timing of surgery was classified as immediate or delayed based on median age of intervention stratified by type of obstruction. Primary outcomes were primary treatment failure, respiratory function and mortality rates. RESULTS: A total of 2765 abstracts were identified and screened by 2 independent reviewers. Of the 688 articles reviewed in full text, 23 articles met the study criteria and were subjected to quality assessment. The full study assessment and quality control measures yielded 23 studies (representing 362 patients) for pooled patient-level analysis in the systematic review. Primary treatment failures occurred in 24.8% of patients that underwent immediate surgery and 42.6% of patients that underwent delayed surgery for bilateral choanal atresia (p = 0.01). There were no differences in mortality rates (5.6% vs 4.2%; p = 1.00) or qualitative measures of respiratory function. There were no difference in treatment outcomes for patients with unilateral choanal atresia (p > 0.05). CONCLUSIONS: Through an analysis of pooled individual patient data, this systematic review of the literature demonstrated that there was significantly higher rates of treatment failure in patients that underwent delayed surgery for bilateral choanal atresia. Clinical trials and large prospective cohort studies investigating outcomes following immediate and delayed surgical intervention will provide further insight into treatment strategies.
