The elastic flap for lip repair.

These cases illustrate a new concept in lip repair. This approach recognizes the great inherent elasticity of the oral cavity and takes advantage of the florid blood supply of the region. Recent laboratory studies of Taylor et al., as well as the works of Manchot and Salmon, are combined with anthropologic observations of tribal customs to formulate another way of looking at lip reconstruction. Triangularization of surgical defects, lip switching, and mobilization of distant flaps are avoided by taking advantage of stretched local tissues. Preoperative expansion is discussed as a future option.
