Radiofrequency ablation is an effective treatment for localized, superficial microcystic LM in the oral cavity. Pediatric patients tolerate the treatment with rapid postoperative recovery and minimal complications. The majority of patients required a short hospital stay for observation of the airway. Virtually every patient resumed oral diet by the time of discharge. Radiofrequency ablation is the treatment of choice at Children's Hospital Boston (CHB) for patients who present with symptomatic, superficial, and localized intraoral microcystic LM. For lesions involving deeper structures, multimodal treatments including surgical and sclerotherapy may be necessary.
