These conditions can increase pressure inside the skull, and if left untreated, may lead to dangerous complications like brain herniation. To manage this, a common procedure called decompressive craniectomy is performed to reduce intracranial pressure. While this surgery often stabilizes the patient's condition, it leaves a cranial defect that exposes the brain to external risks, including pressure fluctuations and potential damage. In severe cases, patients with larger defects may develop complications such as sinking skin flap syndrome.\n\nCranial reconstruction, also known as cranioplasty, is an important procedure to restore the skull's structure and protect the brain. This surgery can improve brain function, stabilize intracranial pressure, and enhance the patient's appearance. While cranioplasty is a standard neurosurgical procedure, it has a relatively high risk of complications compared to other brain surgeries. Common complications include infections, bleeding, hydrocephalus, and seizures. In severe cases, complications may lead to the failure of the reconstruction.\n\nUnderstanding the factors that contribute to complications after cranioplasty is crucial for neurosurgeons to improve outcomes and reduce risks. This study aims to identify these factors and develop predictive models for postoperative complications of cranioplasty.",[97,98,99],"Cranioplasty","Postoperative Complications","Risk Assessment",[97,98,101,102,103],"Risk factors","Retrospective Study","predictive model","2025-06-02",{"date":106,"type":107},"2025-06-05","ACTUAL",{"date":109,"type":107},"2024-12-17",{"date":111,"type":93},"2025-12-31",{"name":5,"class":6},3]
