聚丙烯酰胺水凝胶面部注射术并发症分析

目的 探讨聚丙烯酰胺水凝胶面部注射充填凹陷后并发症产生的原因及处理办法。方法 1999年以来，对8例聚丙烯酰胺水凝胶面部注射充填后发生并发症者的临床资料进行了总结。术前部分患者行MRI检查，所有患者均行手术治疗。结果 8例面部注射层次据分析可能分别注入颞浅筋膜浅层、颞筋膜下疏松结缔组织、皮下组织以及眼轮匝肌内。颞部注射充填层次注入颞浅筋膜浅层者，充填物可沿SMAS向四周包括面部蔓延；注入颞筋膜下疏松结缔组织中者，充填物可经颧弓深面再向前沿面颊脂体蔓延至颊部。8例并发症均经手术治疗，术后症状得到改善，获较满意疗效。结论 聚丙烯酰胺水凝胶不适于面部注射充填，聚丙烯酰胺水凝胶面部注射充填的安全性值得商榷。

Complication of polyacrylamide hydrogel injection for facial plasty

Objective To investigate the causes of complications of polyacrylamide hydrogel injection for facial plasty and reliable treatments. Methods Eight patients were included in the study.Some of them were examined by MRI.All the patients received surgical treatments. Results The injected polyacrylamide hydrogel was found in the superficial layer of the superficial temporal fascia,the loose connective tissue below the deep temporal fascia,the subcutaneous tissue or the orbicularis muscle.Polyacrylamide hydrogel injected into the superficial layer of the superficial temporal fascia could spread to the face along the SMAS.Polyacrylamide hydrogel injected into the loose connective tissue below the deep temporal fascia could spread down to the cheek.The patients' symptoms were relieved with the operation.Satisfactory results were obtained. Conclusion Polyacrylamide hydrogel injection does not adapt to facial plasty.The reliability of polyacrylamide hydrogel injection for facial plasty is in doubt.
