The double-door tongue flap for total cheek mucosa defects.

Lining of total cheek mucosa defects can be accomplished by opening the tongue along its lateral border and preparing two myomucosa flaps that can be swung upward and downward like a double door to be sutured into the defect. The tongue is released 3 weeks later in a second-stage operation. The operation is quick and easy compared with other methods to achieve lining for such defects. Tongue function is not impaired after healing of the second-stage operation.
