The Adult Facial Flex microstomia prevention appliance (MPA) uses dynamic bands to stretch the lips and provides resistance for muscle training and to prevent microstomia. The system includes the Facial Flex and various resistance bands. Bands should be changed weekly and can be purchases as needed.
As microstomia usually develops over time, prevention with an appliance like the Facial Flex can reduce the occurrence of microstomia. Contracture of the lips from burn scarring and tissue fibrosis may be limited by early intervention with a microstomia prevention appliance (MPA).
The Facial Flex is an external and horizontal microstomia prevention appliance. Dynamic force from replaceable bands presses the lips apart to prevent the closing of the lips in microstomia.
Horizontal microstomia prevention appliances are not indicated and does not prevent lower lip eversion when the scar is placed adjacent to the vermillion borders. Additionally, horizontal microstomia prevention appliances may cause skin breakdown and prevention retention of oral secretions.
