Syme Method.
Blasius Method.—The method of Blasius is very similar to the foregoing, except that this author does not carry his two curved incisions as far downward and backward (see [Fig. 233]).
The two semilunar flaps are made from the tissue of the anterior chin and slid upward, and sutured in the median line and to the intermedian spur of undisturbed tissue, as in [Fig. 234].

Blasius Method.
Bürow Method.—Bürow, who favors the excisions of two triangles of healthy tissue in restoring an entire loss of the lower lip, proceeds by ablating the diseased area in triangular form. From the angles of the mouth he cuts two transverse incisions, upon which he outlines two triangles, as in [Fig. 235].
The tissue included in these triangles is removed entirely, an unnecessary loss and one unwarrantable, but he saves the mucosa of these excised portions with which he lines the upper margin of the newly formed lip.
The freed lateral chin flaps he slides forward so that their oblique borders meet vertically in the median line, where they are sutured.
