Practice Question # 681.



Craniotomy is the surgical procedure in which a part of the bone scull is removed to allow the surgeon to have access to the brain.

Special surgical apparatus are used to remove the part of the bone called the bone flap. The bone flap is temporarily removed until the surgery is completed and is then repositioned with the use of special titanium plates.

Types of craniotomy and neuronavigation.

There are several types of craniotomy depending on the location of the lesion, for instance:

  • Classical craniotomy.
  • Endoscopic craniotomy.
  • Key hole craniotomy.
  • Posterior sigmoid
  • Translabyrinth craniotomy.
  • Hypo-occipital craniotomy.

Endoscopic craniotomy is another type of craniotomy which involves inserting an endoscopic camera into the brain through a small incision in the scalp. It is usually used for intraventricular tumors or for endoscopic third ventriculostomy in cases of hydrocephalus.

Craniectomy is a similar procedure involving the permanent removal of a part of the skull. This is usually performed where there is swelling of the brain before or after a brain surgery and in cases of infection.
