Haagedorn Method.—Haagedorn’s method does not differ much from the above. The incisions are shown in [Fig. 180], the appearance of the freed margins in [Fig. 181], and the sutured wound in [Fig. 182]. The prolabial flaps are somewhat alike in size in this operation, in which it differs only in the method just considered.

Geuzmer Method.—Geuzmer so incised the cicatrized defect that a small prolabial flap is formed from the median border and a larger one from the lateral, the very opposite of the Haagedorn technique.
Dieffenbach Method.—To facilitate the mobility of the lip flaps, Dieffenbach has added two additional incisions on either side of the nose, in circular fashion, encircling the alæ of the nose, as shown in [Fig. 183]. This procedure is hardly ever necessary in harelip, and truly applies to the restoration of a considerable loss of tissue of the upper lip occasioned by the extirpation of cancerous growths, although clefts of the median variety might be corrected thereby.
The wound thus formed appears as in [Fig. 184]. The sutures are placed as in [Fig. 185].
