The cuts show the result of a caseoperated upon by Page^ (Figs. 36 and 37). Prominent Ears.—Occasionally the aurist is called uponto relieve the deformity caused by prominent ears. Ifseen in infancy the wearing of a tape cap may be Fig. 37.—The same ear as in Fig. 36 after operation. Withpermission. This is so constructed that when in position the auriclesare held in contact with the head by tapes passing overthem. Continued wearing of this device results in theears assuming a more normal position. The caps may bepurchased in shops specializing in childrens goods. In 1 Tr. Am. Otolog. Soc, 1914. 88 DISEASES OF THE EXTERNAL EAR adults the deformity may be due to a redundance of thecartilage or merely to a laxity of skin and contiguoustissue. In the former case in order to correct the deformityit is necessary to remove some of the cartilage or, as inan operation devised by Goldstein, to reduce the size ofthis structure by overlapping it. A curvilinear incisionis made on the posterior surface of the auricle and theskin separated from the cartilage. This is now incisedin a manner similar to that adopted in submucous resectionof the septum, the incision merely passing through thisstructure and not the soft parts on
