The invention discloses an elastic deformable skull base bone defect repairing bracket. The elastic deformable skull base bone defect repair bracket includes a bracket body, the bracket body includesa functional layer and a base layer, the functional layer includes a top layer and a bottom layer, the top layer and the bottom layer are connected by the base layer, wherein the functional layer hasa first porous structure, which is mainly prepared from a first polymer material, and the first polymer material accounts for 85% to 100% of the mass of the functional layer; the base layer has a second porous structure prepared by mixing a calcium phosphate-based biomaterial and a second polymer material, and the mass of the calcium phosphate-based biomaterial accounts for 60 wt% to 80 wt% of that of the base layer. The bracket of the invention has both a certain elasticity and expansion function, can be compressed and folded, is convenient for implantation into an injured area, is easy to operate, can reduce intraoperative surgical incision, and reduces the degree of injury to patients. The bracket of the invention has good effect and clinical application value in repairing the defect ofthe skull base bone.
