Otoplasty for moderately severe constricted ear deformity

Constricted ears showed a spectrum of deformities confined to the upper third of ear. Characteristically, constricted ears presented with four anatomical features including helical lidding, protrusion, decrease ear size, and low ear position. Based on these features, Tanzer and Cosman had classified the deformities into groups and proposed treatment to each group. Numerous surgical techniques in correction of constricted ears had been described in the previous literatures. We demonstrated a simple one-stage modified Chongchet technique via posterior approach consisting of anterior cartilage scoring, mastoid hitch, and an inverted triangular supra-auricular skin incision in the surgical correction of a moderately severe Tanzer IIA constricted ear deformity with satisfactory outcome. In addition, the details of surgical techniques including its benefits, shortfalls, and outcomes were reported, and literature review on surgical approach to moderately severe constricted ear deformities were shown.
