Objectives:
Craniectomy is widely performed to lower the intracranial pressure in various conditions, such as traumatic brain injury, stroke, or brain swelling. Several complications can occur after craniectomy and cranioplasty, which significantly affect the prognosis of the patients after surgery. We studied the complications of craniectomy and cranioplasty and the factors affecting prognosis after the operation.
Methods:
Patients who underwent cranioplasty after craniectomy at Daejeon St. Mary's Hospital from 2015 to 2021 were included. We retrospectively reviewed their medical records and images. All patients were classified according to their sex, age, clinical grade, and diagnosis. Complications after craniectomy and cranioplasty were investigated for 1 year after surgery. The complications included postoperative hemorrhage, infection, hydrocephalus, and bone resorption.
Results:
This study included 104 patients. Complications after decompressive craniectomy were significantly frequent in patients with hypertension history (p=0.03). In contrast, complications of cranioplasty were significantly frequent in patients with history of diabetes mellitus, hepatic failure, or trauma (p=0.03, p<0.01, and p=0.01, respectively). Artificial bones were used more frequently than autologous bones in patients with trauma (p=0.03); however, there was no difference in the incidence of complications between them (p=0.64).
Conclusion:
Hypertension is a significant risk factor for decompressive craniectomy complications, especially rebleeding. Diabetes, hepatic failure, and trauma are significant risk factors for cranioplasty complications. There was no statistical difference in the incidence of complications between the use of autologous and artificial bones.

01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
