Weber Method.—The flap is made from half the thickness of the upper lip, as shown in [Fig. 438], and brought into the defect, as in [Fig. 439]. The pedicle is cut later.

Weber Method.
Thompson Method.—This author uses a lateral flap taken from the cheek, as shown in [Fig. 441], and lines it with a flap of mucosa dissected from the septum antero-posteriorly, as shown in [Fig. 440], disposing of the latter flap as shown. The raw surface meets the raw surface of the skin flap, as in [Fig. 442].
At a later sitting the two pedicles must be severed and adjusted by small minor operations.
