CO2 Laser Treatment of Leukoplakia of the Tongue: A Case Report and Literature Review
Khan, Mohammed Nasiruddin / Dawasaz, Ali Azhar / Thukral, Naresh / Jangam, Daya
Leukoplakia is a potentially premalignant lesion affecting the oral cavity (malignant transformation rate of 24% of tongue cases).9 The invasive nature of premalignant lesions together with their large and innocuous extent influences the treatment. The common modalities of treatment of these lesions are surgical excision, cryotherapy, and electrosurgery. Diffuse lesions are difficult to manage by excision and can result in severe disability. CO2 lasers have been in use for about 40 years, and provide some benefits in comparison to conventional surgical procedures. Less pain, little bleeding, minimal postoperative edema, reduced risk of infection, and low recurrence rates were advantages observed following CO2 laser surgery in the mouth when compared to other modalities of treatment. Here we present a case of leukoplakia of the tongue surgically treated using CO2 laser. Postsurgical healing progressed well with no postoperative complications; re-epithelialization was complete after 4 weeks. The lesion was kept under observation for a period of 6 months with no recurrence. Thus, we conclude that laser can be considered an excellent form of treatment for the surgical management of leukoplakia.
