Complication of polyacrylamide hydrogel injection for facial plasty / 中华整形外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the causes of complications of polyacrylamide hydrogel injection for facial plasty and reliable treatments.</p><p><b>METHODS</b>Eight patients were included in the study. Some of them were examined by MRI. All the patients received surgical treatments.</p><p><b>RESULTS</b>The injected polyacrylamide hydrogel was found in the superficial layer of the superficial temporal fasica, 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.</p><p><b>CONCLUSION</b>Polyacrylamide hydrogel injection does not adapt to facial plasty. The reliability of polyacrylamide hydrogel injection for facial plasty is in doubt.</p>
