At Sikarin Hospital, Lesionectomy is performed using advanced neurosurgical techniques and detailed preoperative brain mapping. Established in 1979, the JCI accredited hospital in Bangkok, Thailand has 354 beds and provides comprehensive neurosurgical and neurological care.

Lesionectomy may be considered for selected patients with drug-resistant focal epilepsy when a specific structural lesion is responsible for seizure activity. During the procedure, the neurosurgeon accesses the affected area and removes the identified lesion, sometimes along with a small margin of surrounding abnormal tissue when clinically appropriate. Detailed imaging, video EEG, and functional testing may be used before surgery to confirm the seizure focus and assess nearby critical brain regions. Postoperative monitoring helps evaluate seizure control and neurological recovery.
