=Busch Method.=—The same method as above is employed except that for the incision _A_, _C_, which, upon dissection of the skin in triangle _A_, _B_, _C_, allows the closure of a larger defect than could be corrected with the lateral nasal flap alone (see Fig. 426). [Illustration: FIG. 426.—BUSCH METHOD.] The following illustrations are similar to those given and involve only the skin in the flaps made, as shown. They are only of interest in portraying the position of the flaps and their pedicles. [Illustration: FIG. 427.—DIEFFENBACH METHOD.] [Illustration: FIG. 428.—DUPUYTREN METHOD.] [Illustration: FIG. 429.—FRITZ-REICH METHOD.] [Illustration: FIG. 430. FIG. 431. FIG. 432. FIG. 433. SEDILLOT METHOD.] [Illustration: FIG. 434. FIG. 435. NÉLATON METHOD.] In the Bonnet method the flap is taken from the entire thickness of the upper lip and by twisting is brought into the defect. The pedicle must be cut at a later sitting. [Illustration: FIG. 436. FIG. 437. BONNET METHOD.] =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. [Illustration: FIG. 438. FIG. 439. 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. [Illustration: FIG. 440.—Mucosa flap. FIG. 441. FIG. 442. THOMPSON METHOD.] =Blandin Method.=—The flap is made of the whole thickness of the lip. The pedicle is cut at a second sitting. [Illustration: FIG. 443. FIG. 444. BLANDIN METHOD.] =Von Hacker Method.=—This author adds a flap from the nasolabial region to line that taken from the healthy side of the nose, as shown in the Langenbeck method. There is little cicatrization here, and the result is excellent for defects of large area. The procedure and shape of flaps as used are shown in Figs. 445 and 446. [Illustration: FIG. 445. FIG. 446. VON HACKER METHOD.] =Kolle Method.=—The author dissects away the flap _E_, _A_, _D_ when part of the mucosa and cartilaginous tissue remains, and where there is a loss, total or partial, of the alar rima, the transverse incision _E_ being made as long as required to overcome the defect by sliding, as in Fig. 447. The latter flap is freshened at its inferior border along the line _D_, and a second or bordering flap of sufficient width to line and face the nostril is taken up from the upper lip, skin only, as shown in area _C_. The lateral or upper flap is now slid down to slightly overcome the loss of tissue and the flap _C_ is brought upward by twisting slightly on its pedicle and sutured in place, as shown in Fig. 448.
