The aim of this study is to use porous high-density polyethylene grafts (Medpor) in open rhinoplasty and then assess complication rate and aesthetic outcomes.
In a prospective cohort study, we performed open rhinoplasty and employed Medpor as rhinoplasty grafts. Then we compared their complication rate.
In a total of 64 patients, 84 Medpor grafts--8 dorsal grafts, 23 strut grafts, 8 rim grafts, 5 button grafts and 10 spreader grafts--were utilized. Moreover, 5septal perforation repairs with Medpor were performed. The complication rates were 5.3% in dorsal graft (complication in dorsal graft was only movement of implant), 21.7% in strut graft and 25.0% in rim graft. No complication was seen in spreader and button grafts. All 5septal perforation repairs were successfully performed with the same rhinoplasty approach.
Medpor can be used as dorsal and spreader graft in reconstruction of severe nose deformity with lowest complication rate and without infectious complication and extrusion.
本研究旨在将多孔高密度聚乙烯移植物（Medpor）用于开放式鼻整形手术，然后评估并发症发生率和美学效果。
在一项前瞻性队列研究中，我们进行了开放式鼻整形手术，并使用Medpor作为鼻整形移植物。然后我们比较了它们的并发症发生率。
总共64例患者使用了84块Medpor移植物，其中8块鼻背移植物、23块支撑移植物、8块边缘移植物、5块纽扣状移植物和10块撑开移植物。此外，还进行了5例使用Medpor的鼻中隔穿孔修复手术。鼻背移植物的并发症发生率为5.3%（鼻背移植物的并发症仅为植入物移位），支撑移植物为21.7%，边缘移植物为25.0%。撑开移植物和纽扣状移植物未出现并发症。所有5例鼻中隔穿孔修复手术均采用相同的鼻整形手术方法成功完成。
Medpor可作为鼻背和撑开移植物用于严重鼻畸形的重建，并发症发生率最低，且无感染性并发症和排斥反应。
