Fiber optic CO2-laser induced emphysema of the supraglottis

Abstract

Subcutaneous emphysema is a rare but well-defined surgical complication. However, emphysema of the supraglottic mucosa has not been described in the literature. We present a case of a 2-year-old male who suffered supraglottic emphysema secondary to fiber optic CO₂-laser use during laryngeal cleft repair. The patient required preemptive postoperative intubation; however, there were no long-lasting adverse effects at 6 and 12 weeks follow up. This report illustrates a rare CO₂-laser complication and describes its sequela.
