ObjectivesTraditional supraglottoplasty for pediatric laryngomalacia is most commonly conducted with either CO2 laser or cold steel instruments. While the procedure enjoys high success rates, serious complications such as excessive bleeding, supraglottic stenosis and aspiration can occur. Unilateral coblation supraglottoplasty may reduce this risk, but data on respiratory and swallowing outcomes are lacking. This study reports our experiences with unilateral coblation supraglottoplasty.MethodsPediatric patients with severe congenital laryngomalacia who underwent unilateral supraglottoplasty at a single institution from 2013 to 2016 were retrospectively reviewed. Bipolar radiofrequency ablation (Coblation) was utilized with partial arytenoidectomy, aryepiglottoplasty, and advancement of mucosal flaps. Outcome measures included apnea-hypopnea index (AHI), weight-by-age percentile, and decannulation rate.ResultsTwelve patients were included with an average age of 13.1 months (range 2–28 months). In patients without tracheostomy, 88% had complete resolution of respiratory symptoms, while the remainder had significant improvement. In patients without gastrostomy tubes, there was an average increase in weight-age percentile of 6.1, 7.8, and 15.3 points at 1, 3, and 6 months postoperatively, respectively. Three patients had complete polysomnography data with a mean preoperative AHI of 19.3 and postoperative AHI of 4.0. Three of four patients with tracheostomy have been decannulated at a mean follow-up of 1.5 years. There were no early or late postoperative complications and no revision supraglottoplasty.ConclusionUnilateral supraglottoplasty with bipolar radiofrequency ablation can improve respiratory symptoms and decrease OSA severity in severe congenital laryngomalacia. This technique is safe and can lead to substantial improvement in AHI in patients with OSA.
