Postoperative Relief of Upper Airway Obstruction: CSS versus CLS.

		Improved UAO	Persistent severe UAO requiring tracheostomy
Without neurological comorbidities	CSS(𝑛=18)	100%	0%
	CLS(𝑛=21)	85.7%	14.3%
		𝑃=.61	𝑃=.61

CSS: cold steel supraglottoplasty; CLS:CO₂ laser supraglottoplasty; UAO: upper airway obstruction.
