Although porous polyethylene (PPE) implants are already used in reconstructive craniofacial surgery, they are still only applied in rhinoplasty when critically indicated. Biocompatibility of PPE implants (pore size ~100-200 µm) can be modified by tissue engineering: coatings with extracellular matrix
