Use of a 1.94-µm Fiber Laser in the Surgical Management of Patients with Oral Epithelial Dysplasia

BACKGROUND: The choice of optimal surgical technique for treating potentially malignant oral mucosal disorders with the signs of epithelial dysplasia remains a subject of ongoing debate. This is associated with the absence of a widely adopted method in dental practice that guarantees the most successful outcome. Laser technologies offer improved precision and enhanced therapeutic efficacy for these patients. However, there is a notable lack of studies — both Russian and international — specifically evaluating the use of fiber lasers in managing dysplastic epithelial lesions of the oral mucosa.

CASE DESCRIPTION: This case report presents the surgical excision of oral epithelial dysplasia using a fiber laser, aiming to enhance treatment effectiveness. A 1.94-µm fiber laser was applied in the treatment of verrucous leukoplakia with signs of epithelial dysplasia, which has a malignant transformation rate of up to 65.8%. As a result of the fiber laser treatment, a favorable postoperative period was observed, with no esthetic, functional, or phonetic impairments noted in the long term.

CONCLUSION: A 1.94-µm fiber laser offers high efficacy in the surgical treatment of patients with potentially malignant oral mucosal disorders presenting with epithelial dysplasia.
