New Diode Laser for Immediate Pain Attenuation Following Snowy Dry Ice Treatment for Naevus of Ohta
Snowy dry ice application followed by epithelial peeling is an effective treatment for Ohta’s naevus. However, it is quite painful. The GaAlAs diode laser has been found to be effective in pain attenuation. A retrospective study of 452 patients is presented, using the diode laser for immediate pain attenuation following snowy dry ice application and epithelial peeling. One group of 100 patients participated in an additional separate study to determine the time course for pain recovery after dry ice application alone without laser or peeling. A second group of 100 patients participated in a second study to evaluate recovery and determine the time course following peeling without laser irradiation. In all cases the laser proved effective in attenuating the perceived pain by 60%, and shortening the overall recovery time by 37%, with minimal (0.7%) and controllable side effects.
