Endoscopic laser treatment for pediatric nasal allergy.

We have used the carbon dioxide (CO(2)) laser and the gallium aluminium arsenide (GaAlAs) diode laser with flexible fiber delivery instruments for vaporization of the inferior nasal turbinate in pediatric patients since 1993. Under endoscopic control, the whole inferior turbinate was vaporized by 5-10 W laser output delivered via an optical fiber. Generally, the nasal mucosa changes into normal mucosa, and symptoms improve. The greatest symptomatic improvement was in nasal obstruction. The results obtained by the two laser devices were similar although they have had different characteristics. Endoscopic laser surgery is effective in the treatment of pediatric nasal allergy.
