Perioperative fires inside the mouth can have long-lasting sequelae. They are potentially dangerous both to the patient and to the operation room staff as well. Herein, we present a flash fire in the oropharynx, secondary to electrosurgery during a tonsillectomy operation in a young child. Despite a potentially devastating situation, the patient recovered well within just a week following intraoral burn injuries, and the initially interrupted tonsillectomy operation was completed without complications. The dangerous situations leading to fire hazards and the prevention measures are discussed.
