Surgeons have been working on a new surgical technique for people with severe epilepsy. The technique has been used for a few years. Now a research study has shown that it is safe to use and produces good results.
The long name for the surgical procedure is multiple hippocampal transection (MHT). It is done on the part of the brain that is linked to memory and language. The surgery aims to block epileptic circuits. This should control seizures. It was hoped that memory and language would not be badly affected.
Researchers at the University of Nebraska Medical Centre, US have published long-term outcomes for 15 patients who had MHT. They were aged between 25 and 60 years. Patients were followed up for at least two years after surgery.
Fourteen of the patients became seizure-free following the procedure. The fifteenth patient only had the occasional seizure. Importantly, verbal memory was preserved in all of the patients.
The full findings of the study will be published in Seizure: European Journal of Epilepsy.
