Trilobed Flap of Weerda 1979

Occasionally a bilobed flap is insufficient for repairing a cheek defect, which requires one lobe between the ear and defect (Fig. 8.10a), a second lobe behind the ear, and a third lobe in the lateral neck. As in an Esser cheek rotation, the lower limb of the third lobe may be extended below the mandible. Closure of the secondary defects may require the excision of Burow's triangles (Fig. 8.10b).
