huge skull defect
Introduction
Introduction Most of the skull defects are caused by open craniocerebral injury or firearm penetrating injury. Some patients have residual bone defects due to surgical decompression or diseased skull resection. In recent years, due to the high brain pressure of severe craniocerebral injury, the decompressive method of decompressive craniectomy is prevalent, so there are many artificial large skull defects. In fact, a considerable number of patients do not need large cranial decompression. Most of them are decisions made during the surgery, and there are no defects. Defects with a diameter of more than 3 cm, especially those that are unsightly and safe in the forehead, often have symptoms such as dizziness, headache, local tenderness, irritability, and restlessness.
Cause
Cause
1. Open craniocerebral injury or firearm penetrating injury.
2. Unsuccessful comminuted or depressed fractures can be expanded after surgery.
3. Patients with severe craniocerebral trauma underwent decompressive craniectomy.
4. Children with skull fractures. The skull can be enlarged to form a skull defect with the growth of the skull.

Usually the skull defect is less than 3cm, more asymptomatic subtotal decompression or suboccipital decompression. It has thick muscles and fascia covering and can form a tough fibrous healing layer in the defect area. Play the protective role of the original skull on the brain. There are no symptoms in the clinic. The patient's pulsation of the defect area. Bulging, collapsed fear, afraid of the sun. Fear of vibration or even noise, often have poor self-control. Attention is not easy to concentrate and memory loss or depression.
Diagnosis
Differential diagnosis
The diagnosis points are the skull defect and the contents outside the cranial cavity through the defect, and the diagnosis is not difficult. Meningococcal meningocele or meningeal bulging should be considered for differentiation with nasal polyps or pharyngeal tumors, but the diagnosis can still be confirmed under three-dimensional observation of MRI.
