What is a craniotomy and resection of intrinsic lesion?

A craniotomy and resection of intrinsic lesion is performed to remove a lesion from within the human brain. A cut is made over the area of the lesion. Once the cut has been made, a segment of the bone will be removed. If the lesion is not seen on the surface of the brain, then a cut is made into the brain to expose the lesion.

A computerised navigation system may be used to locate the lesion. Once located, the lesion is then removed, and the skull bone is put back and closed with metal plates and screws. The cut can be closed using one of two ways, either with stitches or by using staples. This decision is made depending on how the cut is.

This procedure will require a general anaesthetic.
