Skull fractures can be classified into four major types; linear, depressed, diastatic, and basilar. Of these, a depressed skull fracture presents a high risk of increased intracranial pressure or hemorrhage to the brain. A compound depressed skull fracture results when a laceration over the fracture exposes the internal cranial cavity to the outside environment. Such depressed skull fractures are indicated for elevation if the defect is more than 10 mm and in the presence of brain injury. Frontal bone contour defects result in marked facial deformity which becomes obvious to the observer. Esthetic correction of the depressed frontal bone fracture can be done with autogenous bone grafts or alloplastic materials. Autogenous bone grafts are meant to be the gold standard method of reconstruction, but they harbor the risk of donor-site morbidity. There are various materials available for the reconstruction of depressed frontal bone fractures. This is a case report which illustrates the use of easily injectable, self-setting calcium phosphate bone cement in the correction of a depressed frontal bone fracture measuring approximately 3 cm × 2.5 cm × 1.5 cm.
线性骨折、凹陷性骨折、分离性骨折和颅底骨折。其中，凹陷性颅骨骨折会使颅内压升高或脑部出血的风险增加。当骨折处的撕裂伤使颅内腔与外界环境相通时，就会形成复合性凹陷性颅骨骨折。如果缺损超过10毫米且存在脑损伤，此类凹陷性颅骨骨折就需要进行整复。额骨轮廓缺损会导致明显的面部畸形，很容易被观察者察觉。凹陷性额骨骨折的美学矫正可以使用自体骨移植或异体材料来完成。自体骨移植本应是重建的金标准方法，但存在供区发病的风险。有多种材料可用于凹陷性额骨骨折的重建。这是一例病例报告，展示了可轻松注射的自固化磷酸钙骨水泥在矫正一处大小约为3厘米×2.5厘米×1.5厘米的凹陷性额骨骨折中的应用。
