A variety of implants have been used for nasal augmentation. A new implant made of porous polyethylene has recently been available.
To evaluate the stability (non-extrusion) of MEDPOR porous polyethylene as nasal dorsal implants in Asian patients.
Nineteen patients' charts were reviewed looking for implant displacement, extrusion of porous implants, postoperative bleeding and infection of tissues surrounding the implants in the postoperative follow-ups which range from 3 months to 5 years.
No postoperative bleeding, infection, or displacement or extrusion of porous implants was noted. Explantation was easily performed in one patient.
Porous polyethylene is stable as a nasal dorsal implant in Asians. Explantation can also be performed with ease if needed.
多种植入物已被用于鼻整形术。一种由多孔聚乙烯制成的新型植入物最近已上市。
评估MEDPOR多孔聚乙烯作为亚洲患者鼻背植入物的稳定性（不发生挤出）。
回顾了19例患者的病历，以寻找在术后3个月至5年的随访中植入物移位、多孔植入物挤出、术后出血以及植入物周围组织感染的情况。
未观察到术后出血、感染、多孔植入物移位或挤出。一名患者的取出手术操作简便。
多孔聚乙烯作为亚洲人鼻背植入物是稳定的。如有需要，取出手术也可轻松进行。
