Porous polyethylene implants for nasal reconstruction: clinical and histologic studies

Area of Science:

• Plastic Surgery
• Biomaterials Science
• Craniofacial Reconstruction

Background:

• Medpor, a porous high-density polyethylene implant, is a biocompatible material with established success in facial skeleton reconstruction.
• Previous applications include orbital floor repair and ear reconstruction, becoming standard procedures.
• Limited data exists on its efficacy in nasal framework reconstruction.

Observation:

• Twenty-three difficult nasal reconstructions and four chin augmentations were performed using Medpor implants.
• Patients experienced follow-up periods ranging from 1 to 3 years (mean, 2 years).
• The study included patients with saddle nose deformity and complex, previously operated 'catastrophe noses'.

Findings:

• Medpor implants demonstrated durable and stable aesthetic and functional outcomes in nasal reconstructions.
• The material rapidly vascularizes post-implantation, facilitating soft tissue ingrowth and collagen deposition.
• Two complications (implant exposure, infection) were successfully managed with revision and antibiotics, with no lasting sequelae.

Implications:

• Porous polyethylene implants are a viable option for challenging nasal reconstructions, addressing deformities like saddle nose and post-traumatic defects.
• The material's properties support successful integration and long-term stability in craniofacial applications.
• Medpor also proved effective for chin augmentation, indicating its versatility in facial contouring.
