Brown Modification of the Estlander Flap 1928

An Estlander flap can also be used for larger medial defects involving more than one-third of the lower lip. The defect created by the wedge excision (Fig. 6.44a) is covered by making a three-layer incision through the lower lip at the commissure and advancing the lip into the defect (Fig. 6.44a, b). A superior Estlander flap is then used to close the remaining lateral defect (Fig. 6.44c, d).

Estlander Flap

a A mucosal flap from the anterior margin of the tongue, based on the right or left side, is swung into the defect. b The lip and tongue defects are closed. The pedicle is divided about 3 weeks later, and the residual defects in the lip and tongue are closed.
