452 - Excision of Mucocele with Erbium Laser in Pediatric Patient

Introduction: The mucocele is the most common minor salivary gland associated disease of the oral cavity, It is also among the most biopsied oral lesions in pediatric patients. Prevalence in the lower lip represents up to 80% of cases but it can also be found in the upper lip and tongue. Frequently develops due to trauma in the oral mucosa following extravasation or retention of mucous material from salivary glands in the subepithelial tissue, they are usually asymptomatic but rarely resolve on their own. The treatment of this pathology can be performed by conventional surgery, cryotherapy, laser surgery and laser vaporization. Some benefits reported by using different types of laser is that it provides a safe, quick, minimal bleeding, painful less and high acceptance by the patients.
