Laser Therapy in Lip Venous Lake: A Case Report

Introduction: Venous varices are vascular lesions caused by vasodilatation. These oral cavity lesions are usually seen as papules or dark blue nodules on the tongue’s ventral surface buccal and retro-commissural mucosae. They are generally asymptomatic but may cause problems such as bleeding on trauma or lack of esthetics. Although many treatment modalities exist for these lesions, the laser is a novel and less invasive method. It secures patient satisfaction more than other methods due to the lack of bleeding and pain. Unlike previous laser therapy methods used for cutting and excision of small vascular lesions, in this lesson, the coagulation properties of laser are employed to eliminate the lesion. Case Presentation: To illustrate, a 70-year-old female person was admitted to the dental clinic of the Semnan University of Medical Sciences, Iran, for a dental examination. She has no systemic problems. During the extra-oral examination, the lesion was visualized on the right side of her lower lip, and the initial diagnosis of a venous lake was made. The lesion was asymptomatic and had been present for several years. Likewise, after obtaining informed consent, treatment with a 940-diode laser was performed. Immediately after the irradiation, the lesion disappeared, and after four weeks, the lip’s texture was completely normal. Conclusions: Exploiting the coagulation properties of the laser to eliminate venous lakes is advantageous over other methods because of the lack of bleeding or pain. Furthermore, this method has a shorter healing time.
