Abstract

Among the various causes of microstoma, scar contracture followed by perioral burns accounts for a large proportion. Perioral burns are common in children who have suffered electric shock due to biting electrical wires, and can be caused indirectly by ingestion of chemicals and directly by flame. During the process of wound healing and scar formation caused by perioral burns, the size of the mouth is decreased due to the circumferential characteristic of the perioral muscle. Microstomia with reduced oral size shows functional and aesthetic defects, which are challenging for surgeons to correct during the treatment process. A 59-year-old male patient who had suffered injury as a result of a gas explosion visited our department because of a dental problem. Here, we report an appropriate treatment method for post-burn microstomia that showed excellent cosmetic results and proper mouth opening function by combining bilateral commissuroplasty, double Z-plasty, and scar revision.
