Novel Classification of Posttraumatic Ear Deformities and its Surgical Management.

Abstract

Background Classification of posttraumatic ear deformities and its reconstruction is an uphill task for a reconstructive surgeon as they present in various combinations. In our study, we have described ear deformity as per a new classification and reconstructed the ear accordingly. Method Posttraumatic ear deformity was described under the following four headings: (a) zone of defect, (b) size of defect, (c) missing components, and (d) condition of surrounding skin. Twenty-six posttraumatic ear deformities were operated using postauricular skin flap (14), temporoparietal fascial (TPF) flaps (8), preauricular skin flap (1), intralesional excision (2), and primary closure with chondrocutaneous advancement in one patient. Costal cartilage was used for reconstruction of framework wherever required. Framework elevation was done 4 to 6 months postoperatively. Results Posttraumatic ear deformity was more common in males. Bite injury and road traffic accidents were the common causes. Zones I, II and III were most frequently involved. Four patients complained about size, contour, and projection of reconstructed ear. Three patients were not satisfied by the appearance of junction between reconstructed and residual ear. Four patients in whom the reconstruction was done with TPF, costal cartilage, and thin (SSG) split skin grafts complained of hyperpigmentation of reconstructed ear. Conclusion Classification of posttraumatic ear deformity and its reconstruction is a surgical challenge. Unscarred postauricular skin and TPF flaps are the workhorse flaps for reconstruction of acquired ear deformities. Our classification helps in describing the defect, documenting it, planning reconstruction, and aiding in assessing postoperative outcomes.
