International St. Mary's Hospital offers dedicated Lesionectomy supported by experienced neurosurgeons, advanced neuroimaging, and specialized epilepsy monitoring facilities. Established in 2014, the JCI accredited hospital is situated in Seoul, South Korea and has 808 beds supporting specialized brain surgery.

Lesionectomy involves surgically removing an abnormal area of brain tissue that may be contributing to seizures or other neurological problems. Depending on the underlying condition, the lesion may represent a low-grade tumor, cavernous malformation, focal cortical abnormality, or other structural change. The surgical approach is carefully planned using MRI and other diagnostic studies to identify the lesion and its proximity to important functional areas. Rehabilitation may be recommended when the procedure affects movement, speech, or other neurological functions.
