Reconstruction of acquired sub-total ear defects with autologous costal cartilage.
Acquired sub-total ear defects are common and challenging to reconstruct. We report the use of an autologous costal cartilage framework to reconstruct sub-total defects involving all anatomical regions of the ear. Twenty-eight partially damaged ears in 27 patients were reconstructed with this technique. The defects resulted from bites (14), road traffic accidents (five), burns (four), iatrogenic causes (four) and chondritis following minor trauma (one). Computerised image analysis revealed a median of 31% (range 13-72%) ear loss. An autologous costal cartilage framework was fashioned in all cases. If adequate local skin was available, this was draped over the framework, but in nine cases preliminary tissue expansion was used and in a further three cases with significant scarring, the framework was covered with a temporoparietal fascial flap. Clinical assessment after ear reconstruction was undertaken, scoring for symmetry, the helical rim, the antihelical fold, the lobe position and a 'natural look' to produce a four-point scale; 11 were excellent, 12 were good, two were fair and three were poor. Our experience suggests that formal delayed reconstruction with autologous costal cartilage is to be recommended when managing acquired, sub-total ear deformity.
