2. relief of symptoms due to craniotomy defect.
b) syndrome of the trephined: nonfocal
c) focal deficit related to the defect: e.g. sinking skin syndrome
d) seizures originating in the brain beneath the defect
3. protection from trauma (blunt or penetrating) in area of post-craniotomy or posttraumatic skull defect
4. reduction of irritation of the brain as a result of pressure on and deformity of the surface of the brain. Reducing this irritation may improve seizure control if this is an issue
5. cognitive deficits: may improve following cranioplasty (especially with large defects)
Onset of symptoms may be delayed months to years after the craniectomy
Cranioplasties are performed to protect the brain and correct cosmetic defects, but there is growing evidence that this procedure may result in neurological improvement.
The aim of cranioplasty is not only a cosmetic issue; also, the repair of cranial defects gives relief to psychological drawbacks and increases the social performances.
Cranioplasty is performed mostly after traumatic injuries.
