A mouth splint for severe burns of the head and neck.

An individual mouth splint device that applies continuous or intermittent pressure to stretch commissures and fibrotic muscles in patients treated for microstomia resulting from facial and neck burns is presented. After an individual lip tray is prepared, the method uses the impression and cast of the region of the lips to construct a pink acrylic resin splint. By using the device, split horizontally and activated with a Hyrx screw, an opening of 14 mm can be obtained within 2 weeks. The device is recommended as being easily constructed, inexpensive, almost painlessly inserted, and progressively activated.
