Otoplasty

Abstract
THE purpose of this paper is to present a short review of the history of otoplasty, a discussion of the embryology of the auricle, and a method of surgery for correction of the "protruding ear." Embryology The first evidence of the future ear is seen in the three-week embryo, and heralded by the placode. The placode, however, will become the otic depression, and with the ectodermal proliferation will form the otocysts to eventually become the inner ear. It is not until the end of the fifth week of embryonic life that evidence of the external ear is manifested. The auricle originates from the first and second branchial arches around the intervening first branchial groove. The arches, named mandibular and hyoid, respectively, develop into hillocks which fuse. As embryonic development passes the eighth week, the proportion of hyoid arch mesenchyme increases in relation to the mandibular arch and makes the greater
