Does cranioplasty following decompressive craniectomy improve consciousness?

Background: Cranioplasty (CP) following decompressive craniectomy (DC) is traditionally viewed as a cosmetic procedure having no effect on neurological function in most cases after severe brain injury. However, anecdotal cases of improvement in conscious level after CP have been observed in clinical practice.

Aim: To investigate whether CP is associated with consistent change in level of consciousness.
