Summary: | Laryngomalacia is the most common cause of infant stridor, and obstructive sleep apnea (OSA) is sometimes found concurrently in patients with laryngomalacia. OSA has been shown to improve after surgical treatment of laryngomalacia, but the majority of laryngomalacia patients have spontaneous resolution of symptoms. It is unknown whether their comorbid OSA also resolves. This study seeks to define the incidence of OSA in laryngomalacia and assess for resolution of OSA with polysomnography data.
Retrospective cohort study at a tertiary care academic medical center. All pediatric patients with diagnoses of laryngomalacia or stridor were reviewed, and patients with laryngomalacia confirmed by Otolaryngologist exam were included. All patients with laryngomalacia were recommended to undergo polysomnography.
A total of 108 patients had laryngomalacia confirmed by an Otolaryngologist. Of those patients, 56 completed a polysomnogram, and 44 (79%) were diagnosed with OSA. Among the OSA patients, 34 had no surgery, 5 underwent supraglottoplasty, and 5 underwent adenoidectomy or adenotonsillectomy. Follow-up polysomnograms were performed for 9 non-surgical patients, 4 supraglottoplasty patients, and 4 adenoidectomy or adenotonsillectomy patients. Mean change in AHI was −2.81 without surgery, −8.18 after supraglottoplasty, and −2.94 after adenoidectomy or adenotonsillectomy.
OSA is often present in patients who have laryngomalacia, and the proportion in this population was higher than previous reports. The only significant predictor for obstructive sleep apnea was race, specifically Black/African American. Among patients with follow-up polysomnograms, the largest OSA improvement was in supraglottoplasty patients, but all patients improved. |
