Outcome of carbon dioxide laser therapy for persistent cutaneous viral warts.
Twenty-two adults with persistent, symptomatic viral warts on the hands or feet which had failed to respond to conventional therapy were treated by carbon dioxide (CO2) laser ablation under local anaesthesia. Four patients did not return for follow-up treatment. Of the remaining 18 patients, 12 had plantar warts, the other six had warts on the hands that were mainly periungual. The median duration of the warts prior to laser treatment was 5 years. The areas treated were solitary in eight and multiple in 10 cases. After an average follow-up period of 10 months (minimum 6 months), all of the treated areas were clear of warts in 10 patients (56%), some had cleared in three, and all the treated warts had relapsed in the other five patients. Side-effects were commonly observed, especially post-operative pain, temporary loss of function of the treated part and scarring. The use of the CO2 laser may clear otherwise resistant viral warts but a significant morbidity may occur with this method of treatment.
