• Biocompatible Teflon fluorocarbon polymer (Proplast) and porous polyethylene (Plasti-Pore) are porous alloplastic implant materials that are widely used in reconstructive head and neck surgery. These two materials were used in our study as replacement grafts for defects in three groups of 12 canines. For the first time, Plasti-Pore was found equal and perhaps superior to Proplast in deep implantation, this in the anterior cricoid cartilage when the internal and external perichondrium were preserved. Rejection of both substances occurred when the implant was exposed to air and aerodigestive tract contaminants after the removal of the perichondrium, subglottic, and upper tracheal mucosa. Airway exposure to the alloplasts, even when lined with buccal mucosa, resulted in infection and extrusion, but at a much slower rate.
