Objective To investigate the therapeutic effects of pulsed CO2 laser irradiation in the treatment of syringoma. Methods A retrospective comparison was performed between 28 syringoma patients treated with a pulsed CO2 laser and 30 patients treated with a continuous CO2 laser. The therapeutic effects and treatment complications were compared statistically. Results The treatments were rated effective for all patients in both groups. The outcome was rated " excellent" for 86. 7% of the pulse-treated group and 78. 6% for those treated with continuous las-ing. There was no significant difference between the two groups. There was a significant difference in the rate of pigmentation and atrophic scarring. The pulsed group showed lower levels of both effects than the continuous group. Conclusion The pulsed CO2 laser is a better tool for treating syringoma in terms of safety, efficiency and side effects.
