Single-Stage Modified Postauricular Flap Reconstruction for a Traumatic Helical Rim Defect Following a Human Bite: A Case Report.

Traumatic defects of the helical rim caused by human bites present significant reconstructive challenges because of tissue loss, infection risk, and the need to preserve auricular contour and symmetry. We report a 27-year-old man who presented with a middle-third defect of the left helical rim following necrosis of an initially sutured avulsed flap caused by a human bite injury. After discussion of reconstructive options, including chondrocutaneous advancement and staged flap procedures, a single-stage modified postauricular flap without skin grafting was selected to preserve ear size and minimize donor-site morbidity. The flap was successfully inset with restoration of the helical contour, and postoperative follow-up demonstrated stable healing, preserved auricular shape, and high patient satisfaction without complications. This case highlights that a single-stage modified postauricular flap is a reliable and patient-centered option for reconstruction of traumatic helical rim defects following human bite injuries.
