Subtotal Nasal Reconstruction Using a Custom 3-Dimensional Porous Polyethylene Construct

Abstract

Subtotal loss of the nose is a devastating occurrence. Traditional approaches to reconstruction have employed techniques that sequentially restore the nasal lining, support and external cover using autologous tissues. The results can be quite variable and are heavily weighted on surgical experience and expertise. We report a case of subtotal nasal reconstruction using a computer generated, 3-D printed porous polyethylene (PPE) scaffold. The patient is a 64-year-old man who presented with a sub-total nasal defect following excision of recurrent basal cell carcinoma. The missing parts comprised the distal half of the composite nose including the nasal floor and lining. The replacement nose was constructed on the patient's right radial forearm. A computer generated PPE nasal scaffold was prelaminated with a forearm flap for lining and a free temporal fascial flap and skin graft for external cover. Following healing, nostrils were created and the nasal construct was then microsurgically transferred to the face. At 18 months post-op, the reconstructed nose has remained stable and functional with excellent aesthetic appearance. The implications for use of 3-D scaffolds for composite nasal reconstruction are enormous.
