Background: A skull fracture widely occurs in patients with traumatic brain injury, leading to intracranial hematoma, brain contusion, and intracranial infection. It also influences the prognosis and death of patients. This study aimed to discuss cases of patients with comminuted skull fractures. Methods: From October 2015 to December 2018, 38 patients with comminuted skull fractures were admitted to the hospital. All patients underwent three-dimensional reconstruction of computed tomography scan images. Digital subtraction angiography or magnetic resonance venography was performed to find out the venous sinus. The clinical findings of the patients were significant regarding gender, age, injury mechanism, location, admission Glasgow Coma Scale (GCS), combined epidural, subdural, cerebral contusion, intracranial pneumatosis, maximum depth of depression, admission to surgery, dural tear, post-operative cerebrospinal fluid leakage, post-operative infection, and Glasgow Outcome Scale (GOS) 3 months after surgery. Results: The incidence of traffic accidents, fall from a height, railway accidents, fall of an object, and chop injury was 60.5%, 18.4%, 13.2%, 5.3%, and 2.6%, respectively. Intra-operative dural trar negatively correlated with epidural hematoma, cerebral contusion, and subdural hematoma. Also, post-operative infection negatively correlated with intracranial pneumatosis, depth of fracture depression, and pre-operative cerebrospinal fluid leakage. No correlation was found between contusion, subdural hematoma, intracranial pneumatosis, depth of fracture depression, and post-operative infection. The GOS score positively correlated with age, pre-operative cerebrospinal fluid leakage, and admission GCS score. Conclusions: A perfect pre-operative examination is a key to successful surgery. Further studies should be conducted to find out more effective treatments for traumatic comminuted skull fractures.
