Summary
The current authors reconstructed the auricles of congenital microtia patients with
a two-stage method using autogenous costal cartilage. In the first stage, lobule rotation,
fabrication of the cartilage framework, and implantation of the framework were performed.
In the second stage, elevation of the auricle using transplantation of the costal
cartilage and two local transposition flaps, formation of the tragus, and deepening
of the concha were performed. A total of 125 consecutive patients were treated, ranging
from seven to 53 years old, from 1990 to 2003. Sixty-nine patients were males and
56 patients were females. Unilateral microtia was present in 114 patients (right 73,
left 41), bilateral in 11 patients. Ninety-four cases were the classic sausage-shaped
lobule type deformity; the remaining 42 cases presented concha-type deformity. The
follow-up period was 6 months to 10 years. One hundred and eighteen cases presented
acceptable ear contour after ear reconstruction. Unfavourable results were blunted
convolution of the reconstructed ear because of thick fibrous tissue in six cases,
mild absorption of carved cartilage by infection in two cases, deformation of the
constructed helix occurred in four cases, less projection of the elevated ear in three
cases, and hypertrophic scars in three cases. Our procedure produced acceptable contour
of the reconstructed auricle with fewer complications than conventional procedures.
In addition, careful meticulous manipulation is necessary to create natural contour
of the ear and to reduce complications in all stages.
