Middle-third helical rim defects may arise from trauma or oncological resection, and pose a challenging reconstructive problem. Reconstructing defects larger than 2 cm using traditional methods commits patients to the inconvenience of staged procedures.
This paper describes a single-stage helical rim reconstruction technique using a post-auricular bipedicled flap and ipsilateral conchal cartilage graft for delayed middle-third helical rim reconstruction.
Two examples of this technique used in post-trauma and oncological reconstruction cases are presented, with pre- and post-operative photographs provided for demonstration.
Contralateral graft harvest and staged operations for helical rim reconstruction are associated with donor site morbidity and the inconvenience of multiple operations to achieve the desired reconstructive outcome. Our single-stage helical rim reconstruction technique was well tolerated by patients, and showed satisfactory aesthetic results in terms of size and symmetry.
