Jäsche Method.
Trendelenburg Method.—Trendelenburg has modified the method of Jäsche by shortening the curve of the cheek incisions so that their outer borders were made to lie anterior to the facial artery (see [Fig. 222]), the parts being approximated and sutured, as shown in [Fig. 223].
To obtain sufficient mucous membrane to cover the superior margin of the two flaps when brought together he made the cheek incision only down to the mucosa, dissected up the latter a short distance from the upper part of the cheek, and divided it about one half centimetre above the line of the external incision. This flap of mucous membrane on either side was used to line the lip in place of the prolabium.

Trendelenburg Method.
Bruns Method.—Bruns excises the defect when not involving the whole lip in quadrilateral form, and takes up a flap from the anterior region of the chin to cover it, as shown in [Fig. 224].
This flap is rotated upward into the wound made, and is sutured in place, as shown in [Fig. 225]. The secondary wound is brought together by suture.
