Carbon dioxide laser in the treatment of benign skin neoplasms

Abstract

Purpose: to assess the effectiveness of carbon dioxide laser light in the treatment of benign skin neoplasms.Material and methods. The researchers have analyzed outcomes in 1394 patients treated for benign skin neoplasms. In the main group (n = 1184), laser photocoagulation (vaporization) and laser photohydraulic preparation were applied. Laser surgical devices “Lancet-1” and “Lancet-2” in continuous and pulsed modes, power up to 20 W, focused beam up to 1 mm were used. In the control group (n = 210), traditional techniques (excision and electrocoagulation) were applied.Results. High effi ciency of CO2 laser light for the removal of benign skin neoplasms has been confi rmed. Such a technique has a minimal rate of complications and relapses and satisfactory aesthetic outcomes, compared to the conventional treatment.Conclusion. Carbon dioxide laser light is highly effective for treating benign skin neoplasms.

An experimental study on the application of “blue” (λ = 450 nm) laser light to remove pigmented skin formations

“…На сегодня наиболее перспективным рассматривают удаление ПН с использованием различного лазерного излучения. Для лечения образований применяют пигментно-специфические лазерные аппараты: на рубине (λ = 694 нм), александрите (λ = 755 нм), иттрий-алюминий-гранате Nd: (YAG) -λ = 1064 нм), а также абляционные лазеры: эрбий YAG Er: YAG (λ = 2940 нм) и определенные режимы коротко импульсного лазерного излучения, например СО 2 -лазеров (λ = 10,6 нм) [13,14]. Однако при использовании указанных лазеров не исключено образование гипертрофических и келоидных рубцов, особенно в проблемных Currently, there are numerous methods for treating pigmented skin formations, including CGPN.…”
