Surgical Intervention for Laryngomalacia: Age-Related Differences in Postoperative Sequelae

Abstract

Objective: Identify risk factors and determine perioperative morbidity of children undergoing surgery for laryngomalacia (LM). Methods: A retrospective analysis of the multi-institutional American College of Surgeons National Surgical Quality Improvement Program-Pediatric Database (ACS-NSQIP-P) was performed to abstract patients aged <18 years with LM (ICD-10 code Q31.5) who underwent laryngeal surgery (CPT code 31541) from 2015 to 2017. Analyzed clinical variables include patient demographics, hospital setting, length of stay, medical comorbidities, postoperative complications, readmission, and reoperation. Results: A total of 491 patients were identified, 283 were male (57.6%) and 208 were female (42.4%). The mean age at time of surgery was 1.07 years (range .01-17 years). Younger patients were more likely to undergo surgery in the inpatient setting compared to their counterparts ( P < .001). Infants were more likely to have prolonged duration of days from admission to surgery ( P < .001), days from surgery to discharge ( P < .001), and total length of stay ( P<.0010). Finally, there was no significant difference between age groups with respect to 30-day general surgical complications ( P = .189), with an overall low incidence of reintubation (1.2%), readmission (3.1%), and reoperation (1.6%). Conclusion: This analysis supports laryngeal surgery as a safe surgical procedure for LM. However, younger children are more likely to undergo operative intervention in the inpatient setting, endure delays from hospital admission to surgical intervention, and experience a prolonged length of stay due to their overall medical complexity. Recognition of key factors may assist in optimizing perioperative risk assessment and promote timely procedural planning in this unique pediatric patient subpopulation.
