The efficacy and safety of the flexible fiber CO2 laser delivery system in the endoscopic management of pediatric airway problems: Our long term experience.

OBJECTIVE: To report the use of flexible fiber CO2 laser in the endoscopic management of pediatric airway cases.

METHODS: A retrospective review was conducted of patients who underwent CO2 laser-assisted airway procedures between September 2007 and January 2014 at a tertiary pediatric hospital.

RESULTS: Sixty-eight patients underwent 80 procedures utilizing flexible fiber CO2 laser. Procedures included supraglottoplasty (n = 32), laryngeal cleft repair (type I [n = 10], type II [n = 7], type III [n = 6]), suprastomal granuloma excision (n = 6), cordotomy (n = 4), laryngeal neurofibroma excision (n = 4), laryngeal granulomatous mass excision (n = 1), subglottic stenosis excision (n = 6), division of glottic web (n = 2), subglottic cyst excision (n = 1), and supraglottic biopsy (n = 1). Ages ranged from 8 days to 21 years (median 11 months). No intraoperative or postoperative complications related to the use of laser were noted.

CONCLUSIONS: The flexible fiber CO2 laser can be safely and effectively used to address a variety of pediatric airway lesions. Previously, the use of CO2 laser in minimally invasive airway surgery has been limited due to the articulating arm carrier, absence of a hand piece, and the direct line-of sight view required. The fiber allows the cutting beam to be directed at the site of the lesion and bypasses limitations posed by other laser systems.
