Long-Pulsed 532-Nm Neodymium-Doped Yttrium Aluminium Garnet Laser for Treatment of Facial Plane Warts in 160 Yemeni Patients.

BACKGROUND: Warts in general and plane warts in particular pose a therapeutic challenge for dermatologists. Many treatment modalities exist, with variable success rates, side effect profiles, and precautions. The long-pulsed 532-nm neodymium-doped yttrium aluminium garnet (LP Nd:YAG) laser has not been previously used for this indication. OBJECTIVE: This study was conducted to assess the efficacy and safety of the LP Nd:YAG laser for treating facial plane warts. MATERIALS AND METHODS: A total of 160 Yemeni patients (62 women, 98 men; age range, 5-55 years) were exposed to 1 laser treatment session with the following parameters: wavelength, 532 nm; pulse duration, 20 millisecond; spot size, 2 to 3 mm; and fluence, 25 J/cm2. The end point was graying or whitening of the lesion. Color photographs were taken before and immediately after treatment and at follow-up visits 1, 4, and 16 weeks after the laser session. RESULTS: An overall clearance rate of 92% after only one session was achieved, with minimal and transient side effects. CONCLUSION: The LP Nd:YAG laser is safe and effective for treating facial plane warts, with a success rate of 92% after only one session.
