At International St. Mary's Hospital, the Craniotomy procedure is performed with cutting-edge neurosurgical technology and skilled personnel. Established in 2014, the hospital has gained JCI accreditation and is located in Seoul, South Korea with 808 beds.

Craniotomy is a temporary process of removing a section of the skull, allowing the doctor to reach and operate on the brain. Depending on the patient, various procedures may be implemented related to the brain, such as tumor removal, treatment of bleeding, aneurysm surgeries, etc. Prior to the surgical operation, the patient's brain is subjected to several imaging and neurological tests to determine the optimal course of action and reduce associated risks.
