CO2激光治疗口腔扁平苔藓的研究进展

The research progress of CO2 laser in the treatment of oral lichen planus

口腔扁平苔藓（orallichenplanus，OLP）是常见的口腔黏膜病，其病因不明，治疗较困难，传统疗法对部分患者无效。近年来激光疗法在治疗OLP上取得一定的效果，其中CO2激光因其较好的疗效得到国内外医师和学者的关注。本文主要探讨CO2激光治疗OLP的原理、疗效及新进展。

Oral lichen planus （OLP） is a common oral mucosal disease. The etiology of OLP is not clear. The treatment of OLP is difficult as some of the OLP patients have little effects to the conventional mucosal treatments. In recent years, laser therapy has been adopted to treat patients with OLP. The CO2 laser therapy has drawn much attention of doctors and scholars because of its advantages in treating the OLP. This review article mainly discusses the principle, effects and some state-of-the-art progresses in OLP treatment using CO2 laser.
