The present invention relates to a composite biomaterial and application for facilitating recovery from acute traumatic peripheral nerve injury. The composite biomaterial consists of biodegradable support material and hyaluronic acid solution. The hyaluronic acid solution includes high molecular-weight hyaluronan. The composite biomaterial, while being directly applied onto the site of acute traumatic peripheral nerve injury, is beneficial to anti-adhesion, anti-inflammation, excellent biocompatibility, facilitated axonotmesis recovery, restoration of neurofunction, moisture maintenance of the wound and so on.本發明有關於一種加速急性創傷性周邊神經損傷復元之複合生物材料及其應用。此複合生物材料是由生物可分解性支持材料以及含浸於生物可分解性支持材料中的透明質酸水溶液所組成，且透明質酸水溶液含有特定分子量範圍之透明質酸。上述複合生物材料具有抗沾黏、抗發炎、生物相容性佳、加速神經軸突斷傷復元、恢復神經功能以及傷口保濕等功效，可直接施用於急性創傷性周邊神經創傷處。
