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

Area of Science:

• Otolaryngology
• Plastic Surgery
• Trauma Surgery

Background:

• Traumatic helical rim defects, often from human bites, pose reconstructive challenges due to tissue loss and infection risk.
• Preserving auricular contour and symmetry is critical in ear reconstruction.
• Necrosis of an initial flap in a human bite injury necessitated further reconstruction.

Purpose of the Study:

• To evaluate the efficacy of a single-stage modified postauricular flap for reconstructing traumatic helical rim defects.
• To assess the flap's ability to restore auricular contour, shape, and patient satisfaction.
• To present a patient-centered approach minimizing donor-site morbidity.

Main Methods:

• A 27-year-old male with a helical rim defect post-human bite injury was treated.
• Reconstructive options were discussed, including chondrocutaneous advancement and staged flaps.
• A single-stage modified postauricular flap, without skin grafting, was chosen and performed.

Main Results:

• Successful inset of the modified postauricular flap restored helical contour.
• Postoperative follow-up showed stable healing and preserved auricular shape.
• The procedure resulted in high patient satisfaction without complications.

Conclusions:

• A single-stage modified postauricular flap is a reliable option for traumatic helical rim defects.
• This technique effectively restores ear aesthetics and function while minimizing donor-site morbidity.
• It represents a patient-centered approach for complex ear reconstructions.
