Abstract

A rare auricular malformation with an accessory earlobe is presented, and its method of correction is described. After review of literature, there has not been any previous report of such malformation. Relevant embryologic correlations are discussed. A 13-years-old girl is presented with a bilateral ear deformity that was present since birth. Two bulging masses below both ears and mild indentation of upper lobules were noticed. Bulging masses were removed and indented upper lobules were augmented by composite graft using these soft tissue. The pixie earlobes were also corrected using superiorly based flap of the lobe border. The external ear of the human develops from a fusion of six small hillocks at the region of the first and second branchial arches of the embryo. Although the case is limited to one, it is reasonable to presume that the mild depression of the upper lobule might have been caused by a deficiency of the divided hillock 1.
