We have used the carbon dioxide (CO2) laser and the gallium aluminium arsenide (GaAlAs) diode laser with flexible fiber delivery instruments for vaporization of the inferior nasalturbinate in pediatric patients since 1993. Under endoscopic control, the whole inferiorturbinate was vaporized by 5–10 W laser output delivered via an optical fiber. Generally, thenasal mucosa changes into normal mucosa, and symptoms improve. The greatest symptomaticimprovement was in nasal obstruction. The results obtained by the two laser deviceswere similar although they have had different characteristics. Endoscopic laser surgery iseffective in the treatment of pediatric nasal allergy.
