AbstractBurns around the mouth frequently result in contractures or microstomia. Orthoses used in the past have usually been designed to stretch the mouth horizontally. Finding a comfortable effective way to stretch the mouth vertically proved to be a challenge. A jaw positioner was used for vertical mouth stretching in two case studies and was evaluated for effectiveness of preventing mouth contractures and for comfort, durability, ease of use, adaptability for children, and ease of measuring results. Vertical and horizontal passive range of motion increased with initial use and then was maintained in both patients. The jaw positioner was comfortable and easy to use. This orthosis could be adapted to fit in a child's mouth and was impossible to swallow. Progress was easy to monitor with the numeric scale on the orthosis. Though no single orthosis will be ideal for every oral burn, this jaw positioner is recommended for pediatric and adult patients with extensive circumoral burns who demonstrate fair to good compliance.
