Complex Cranial Surgery is a group of Neurosurgical treatments involving the brain. Conditions that may require Complex Cranial Surgery can include Malignant or Benign Brain Tumors, Brain Aneurysms, Intracerebral Hemorrhages, Subdural Hematomas, and many others. Complex Cranial Surgeries are performed by Neurosurgeons using a number of different techniques depending on the specific condition diagnosed.

Brain surgery may be needed to treat or remove:

• Brain tumors
• Bleeding (hemorrhage) or blood clots (hematomas) from injuries (subdural hematoma or epidural hematomas)
• Weaknesses in blood vessels (cerebral aneurysms) See also: Brain aneurysm repair
• Abnormal blood vessels (arteriovenous malformations; AVM)
• Damage to tissues covering the brain (dura)
• Infections in the brain (brain abscesses)
• Severe nerve or facial pain (such as trigeminal neuralgia or tic douloureux)
• Skull fractures
• Pressure in the brain after an injury or stroke
• Some forms of seizure disorders (epilepsy)
• Certain brain diseases (such as Parkinson' s disease) that may be helped with an implanted electronic device
