Craniotomy is a surgical procedure where a piece of calvarial bone is removed to allow intracranial exposure. The bone flap is replaced at the end of the procedure, usually secured with microplates and screws. If the bone flap is not replaced it is either a craniectomy or cranioplasty.

Classification

There are different craniotomies depending on which part of the intracranial cavity need to be accessed ¹:

frontal
bifrontal
parietal
occipital
pterional (i.e. frontosphenotemporal)
subtemporal
anterior parasagittal
posterior parasagittal
medial suboccipital
lateral suboccipital

Complications

infection including bone flap osteomyelitis, subdural empyema and cerebral abscess
haemorrhage
- intracranial haemorrhage including remote cerebellar haemorrhage
- scalp/subcutaneous haematomas
pseudomeningocoele
tension pneumocephalus
