In accordance with anthropometric studies of the ears, we consider that an aesthetically normal ear measures 6.0 cm in length on the vertical axis and 3.7 cm on the horizontal axis in boys, with ear growth maturing at 13 years of age, and 5.91 cm in length on the vertical axis and 3.37 cm on the horizontal axis, with ear growth maturing at age 12 in girls. When the measurements exceed these averages, we consider that the patient has macrotia. The authors describe a new technique of surgical correction of macrotia that results in an average reduction of 1.7 cm on the vertical axis and 0.8 cm on the diagonal axis with an average surgical time of forty-five minutes, fast learning curve, and little scarring. This technique also allows it to be combined with otoplasty and correction of the lobe length. Because of these items we call the technique High-Performance Macrotia Surgery. Level IV: Evidence is obtained from multiple time series with or without the intervention, such as case studies.展开更多
