L形高密度聚乙烯材料用于短鼻延长术的安全性研究

The Safety Assessment of an L-shaped Polyethylene Sheet Implant for Nasal Elongation

目的探讨L形高密度聚乙烯材料应用于短鼻延长术的安全性。方法对2007年至2009年间的78例接受短鼻手术治疗的患者进行回顾性研究。观察组（38例）采用L形高密度聚乙烯材料植入行短鼻延长术,对照组（40例）未使用该材料。统计两组并发症发生率,进行χ^2检验。结果患者随访平均30.6个月（18个月至5年）。长期随访结果显示,观察组并发症发生率7.8%,严重并发症1例;对照组并发症发生率12.5%,无严重并发症。两组间并发症发生率无统计学差异。结论高密度聚乙烯是一种安全、有效的假体材料,可应用于短鼻延长术。

Objective To evaluate the safety of L-shaped polyethylene sheet implant for nasal elongation. Methods From January 2007 to December 2009, 78 patients received nose elongation were concluded for retrospective study. 38 patients received L-shaped polyethylene sheet implantation were involved in observation group, while 40 patients without polyethylene sheet implantation were involved in control group. All occurring complications were recorded. The incidence of complications was analyzed by Fisher＇s test. Results Patients were followed up for average 30.6 months（18 months to 5 years）. In observation group, the incidence of complications was 7.8 %, and one major complication was observed during the follow-up period. In control group, the incidence of complications was 12.5% without major complication. The exact probability showed no significant difference between the observation and control group. Conclusion The high density polyethylene is a kind of safe and effective implant material for nasal elongation.
