Conchal transposition flap for postburn ear deformities.
Severe thermal injuries to the external ear often lead to extensive loss of peripheral structures such as helix and lobule but frequently spare the more central parts of the ear, even though they may be grossly deformed by scar contracture. The use of spared conchal structures as a transposition flap in combination with remodeling of the residual auricle and release of surrounding scar when indicated has been a useful technique in the reconstruction of a frequently occurring type of postburn ear deformity. Twenty-four ears have been reconstructed in 18 patients over the past 5 years using a conchal transposition flap. The residual concha with its overlying skin can be transposed superiorly, based on a very narrow pedicle in the area of the crus helicis. The raw central area remaining is then resurfaced with a split-thickness skin graft. This technique maximally utilizes the unique remaining auricular elements and can provide a satisfactory reconstruction in selected patients without resorting to more complex and extensive procedures. There have been no significant complications in this series, and patient acceptance of the results has been excellent.
