Epilepsy Surgery

Surgery is considered for an epilepsy patient when treatments with at least three or more appropriate epileptic drug either in combination or when given alone do not improve the seizures. The surgery aims at either stopping the seizures (curative) or reducing their frequency and severity (palliative).

Curative procedures are used when the seizures are associated to a specific region of the brain. It involves removing the specific area of the brain tissue without causing brain dysfunction. Depending on the part of the brain removed they are categorized as temporal lobectomy, cortical excision and hemispherectomy.

Palliative procedures are done when either a specific brain area cannot be associated with the seizure or the specific area overlaps with the critical part of the brain. It involves preventing the spread of the seizures by disconnecting the nerve fibres in the brain by making sections or incisions in the brain. It includes corpus callosotomy and multiple subpial transections. Another palliative procedure is vagus nerve stimulation. It is used to prevent drug resistant major depressive seizures. This involves implantation of a pacemaker like electrical pulse generator on the left side of the chest. This is connected through the wire to two electrodes which are coiled to the vagus nerve in the neck. The patient can switch on the system when a seizure is expected to start. The pulse generator sends electrical impulses to the brain through the vagus nerve when turned on and prevents seizures.
