Partial Ear Reconstruction with a Prelaminated Induced Expanded Radial Artery Flap

Area of Science:

• Plastic Surgery
• Reconstructive Surgery
• Otolaryngology

Background:

• Squamous cell carcinoma resection can lead to significant auricular defects.
• Previous ear reconstruction methods have limitations.
• Aesthetic and functional restoration of the ear is crucial for patient quality of life.

Observation:

• A 76-year-old male patient with a defect of the superior half of the right ear post-squamous cell carcinoma resection was treated.
• No prior reconstruction attempt was made.
• The defect involved substantial loss of the ear structure.

Findings:

• A novel three-stage reconstruction was performed: suprafascial tissue expansion, implantation of a porous polyethylene framework, and coverage with a radial artery free flap.
• The patient reported high satisfaction with the aesthetic and functional outcome at the 1-year follow-up.
• The combined technique demonstrated successful restoration of the ear's form and contour.

Implications:

• This combined approach offers a viable and effective solution for complex partial ear defects.
• It highlights the potential of integrating tissue expansion, alloplastic materials, and free flaps for auricular reconstruction.
• Further investigation into this technique may advance reconstructive surgery for head and neck defects.
