Abstract

OBJECTIVE: To correlate the clinical severity of laryngomalacia (LM) with endoscopic findings, swallowing evaluations and polysomnography in a cohort of patients. Method: We conducted a retrospective analysis between 2017-2018 on a cohort of patients diagnosed with upper airway obstruction (UAO), stridor, noisy breathing or laryngomalacia. This study took place at the Pediatric Pulmonology Department, Riley Children's Hospital, Indianapolis, United States of America. RESULTS:   There were 157 patients with laryngomalacia included in the study. Patients with severe LM were significantly younger than those with mild LM (p=0.0214) and moderate LM (p=0.0220). Subjects with type I of LM were significantly older than type III (p=0.0051). When associations were tested between polysomnogram (PSG) variables and clinical severity, there were significant associations with age at PSG. The overall apnea-hypopnea index (AHI) in mild (p=0.0103) and moderate (p=0.0242) were significantly lower than the severe group. The rapid eye movement (REM) AHI was significantly lower in moderate cases than severe (p=0.0134). The end-tidal carbon dioxide (EtCO2) peak was significantly lower in mild cases than severe (p=0.0141). The total sleep time (TST) peripheral capillary oxygen saturation (SpO2) 90% occurs in both mild (p=0.0197) and moderate (p=0.0498) were significantly lower than the severe group. CONCLUSIONS: The severity of the clinical manifestations of LM did not correlate with the different endoscopic types in our study. The presence of cyanosis was associated with type III LM. Rapid eye movement AHI and EtCO2 in polysomnogram were remained significantly associated with clinical severity.
