Background and Objectives Airway problems frequently occur in neonatal patients requiring intensive care due to high prevalence of intubation history and congenital conditions that are linked to craniofacial or upper aerodigestive tract anomalies. However, many investigations on airway disorders have examined large populations of hospitalized children without focusing on those treated in the intensive care unit (ICU). Here we present the clinical features and outcomes in infants hospitalized with airway-related problems at the neonatal ICU. Subjects and Method A total 69 patients were studied from May 2005 to December 2012, with each examined by an otolaryngologist while in neonatal ICU (NICU) for possible airway problems. Descriptive analysis was used in evaluating illnesses suffered and subsequent upper airway treatments. Factors associated with tracheostomy were identified by multivariate analysis. Results The median age of infants was 30 days (range, 1-237 days), with a male-to-female ratio of 1.38. The median gestational age was 35+3 weeks, and the mean birth weight was 2.35±0.89 kg. Overall, 40 patients had histories of intubation (median duration, 36 days; range, 1-204 days). The most common diagnosis in the upper airway exam was laryngomalacia (n=12), followed by subglottic stenosis (n=10) and micrognathia (n=8). Tracheostomy was performed in 38 patients (55.1%). In multivariate analysis, intubation history was identified as the only variable demonstrating a significant independent association with tracheostomy (p=0.006). Conclusion Upper airway problems in NICU patients are due to a variety of disorders. Precise diagnosis and treatment is achievable through bedside and intraoperative assessments. Patients with a history of intubation are at increased risk of tracheostomy. Korean J Otorhinolaryngol-Head Neck Surg 2017;60(1):24-9
