The following methods for operation are therefore given not so much for their individual merit, but to act as a guide in the selection of an appropriate election or modification for specific cases.
Schwartze Method.—Schwartze advises and has obtained excellent results by removing a long elliptical piece of the entire thickness of the pinna, including both skin and cartilage, from the fossa of the helix, followed by the excision of a triangular section with its base corresponding to the outer border of the helix and its apex terminating well in the concavity of the concha. The scheme of procedure is shown in [Figs. 129 and 130]. The raw edges are brought together by fine silk sutures, which are made to pass directly through the cartilage, and tied carefully to prevent any change of the transfixed parts, which would mar the result of the operation more or less and necessitate further interference. The arrangement of the sutures and the disposition of the parts are shown in [Fig. 131].

Parkhill Method.—Parkhill advises a semilunar incision from the fossa of the helix with a rhomboidal exsection of the helix, as shown in [Fig. 132], and suturing the parts, as shown in [Fig. 133].

The tonguelike ends of the semilunar incisions must, of course, vary in length, according to the amount of tissue necessary to remove to facilitate accurate juxtaposition of the newly designed flaps.
