摘要

The 3 most commonly used allo-plastic materials in rhinoplasty are silicone, expanded polytetrafluoro-ethylene (GORE-TEX; W. L. Gore & Associates Inc), and porous high-density polyethylene (Medpor; Porex Surgical Inc). Silicone is a nonpo-rous materiaLthat does not allow host tissue ingrowth and over time develops a thick capsule surrounding the implant. Most of the complications of silicone are thought to arise from the capsule and include infection and extrusion. GORE-TEX is composed of nodules of poly-te traflu or o ethylene interconnected by fibrils with pores ranging from 10 to 30 mum in diameter. Medpor consists of continuous interconnecting polyethylene pores ranging from 125 to 250 mum.
