Treatment of microstomia caused by burn with a nasolabial flap--an ingenious approach for tugging and fixation of the oral commissure.

Abstract

The objectives of surgical treatment for microstomia due to cicatricial contracture after burn are to obtain sufficient oral aperture, while maintaining sphincter function of the orbicularis oris muscle, and to secure favorable function for eating and conversation in addition to good oral health.The lips of the mouth have a free border, and the oral aperture, which has been enlarged by the operation, tends to be reduced, because of the actions of the orbicularis oris muscle. When the orbicularis oris muscle is resected, putting a priority on sufficient oral aperture and prevention of redevelopment of contracture, the function of the sphincter is often damaged. With the exception of those cases with deep extensive burn that damages a wide area of orbicularis oris muscle, the muscle should be preserved as expeditiously as is practical. In such cases, however, preventive measures for the redevelopment of microstomia should be established. As a postoperative adjuvant therapy, the usefulness of splint therapy has been suggested in many reports. However, a splint should be used for a long period after the surgery, and in some cases, pain is observed with therapy. When a splint is not used for an appropriate period, microstomia may redevelop. It would be ideal to take preventive measures against the redevelopment of contracture during surgery.We provided treatment with some ingenious attempts for the nasolabial flap to a patient with microstomia caused by cicatricial contracture after burn. We obtained favorable results with no postoperative use of a splint.
