이개의 악성 종양 절제와 재건술

Abstract

The auricle is a three-dimensionally complex structure that protrudes outward and is a functionally and aesthetically important physical structure. Approximately 10% of skin cancers originate from the auricle, and appropriate reconstruction according to the characteristics of the defect after complete excision of tumor is important. The auricle is characterized by a lack of subcutaneous tissue due to the skin being tightly attached to the cartilage, limited tissue storage space, and a complex concave-convex shape, which can present considerable challenges to surgeons in reconstructing the defect. In this case, a squamous cell carcinoma that developed in the helical rim was completely removed, and the defect was approximately 33 mm. It was successfully reconstructed using wedge excision, composite excision, and helical advancement. We report this case along with a literature review.
