Types of Tumours

There are numerous forms of brain tumours, ranging from benign lesions to highly malignant cancers, which are amenable to surgical excision. To remove or resect these tumours, a craniotomy is first carried out. This involves the removal of a piece of bone (bone flap) from the skull to allow for access to the brain. The coverings of the brain (dura mater) are then opened over the area of interest. The procedure to remove the lesion will depend on the location of the tumour, the type of tumour and the ease of access to the tumour. An operating microscope may be used to define the fine structures. A “neuron-navigation” device may also be used to achieve even more accurate localisation of the tumour and surrounding structures.

Procedure Completion

At the end of the procedure, the dura is usually sutured closed. The bone flap is usually returned to its position and secured by small metal plates and screws which are non-ferrous (iron-based) which means that they should not set off metal detectors. The scalp incision is closed with staples or sutures.

Further Treatment

Depending on the type of tumour, further treatment may be required. This may include radiation therapy or chemical therapy. A review with your neurosurgeon at Lac-con Neurosurgery will take place between 6-8 weeks following surgery.
