Changes in sleep apnea after supraglottoplasty in infants with laryngomalacia
چکیده انگلیسی

ObjectiveTo determine the clinical and polysomnography outcomes in infants with laryngomalacia undergoing supraglottoplasty.MethodsInfants (<1 year old) who underwent polysomnography pre- and post-supraglottoplasty at our tertiary referral center between 2003 and 2009 were reviewed retrospectively. Outcome measures included changes in stridor, sleep disordered breathing, swallowing, and polysomnography parameters before and after surgery. Pre- and postoperative distributions were compared using a Wilcoxon signed-rank test.Results20 children met inclusion criteria. Statistically significant improvements were found in pre- to postoperative median values for apnea-hypopnea index (AHI) (median change: −6.4 points, p = 0.02) and obstructive apnea index (median change: −2.9 points, p = 0.01) values. Obstructive AHI, O2 saturation nadir, and percentage of sleep spent with <90% O2 saturation improved, although not significantly. Postoperative AHI scores correlated with improvements in stridor in 80% of patients. Stratification showed similar improvements in AHI after supraglottoplasty regardless of reflux treatment, secondary airway lesions, age at supraglottoplasty, or time lag between supraglottoplasty and postoperative polysomnography. Secondary airway lesions are the only potential confounders shown to have significantly better improvements in O2 nadir. While the sleep study improved in patients with AHI >5, infants with AHI <5 had worse polysomnography parameter values postoperatively. Five patients had dysphagia that resolved within one month postoperatively; otherwise, supraglottoplasty resulted in no complications.ConclusionSupraglottoplasty may be an effective and safe option to improve moderate to severe obstructive sleep apnea in infants with laryngomalacia. In addition, polysomnography may be useful in infants with laryngomalacia to identify obstructive sleep apnea and/or to objectively measure outcomes after supraglottoplasty. This pilot study warrants a larger, prospective, and controlled study to validate these findings.
