Head tumor removal is a highly complex neurosurgical procedure that requires exceptional precision and accuracy. The surgery involves vital structures within and around the head, meaning every step must be performed carefully to minimize risks and preserve optimal neurological function. A head tumor itself refers to abnormal tissue growth in the head area that can compress surrounding structures and cause symptoms such as persistent headaches, visual disturbances, and neurological impairment.
Despite the complexity of this procedure, there are neurosurgeons capable of performing it efficiently and safely. At Mandaya Royal Hospital Puri, Dr. dr. Mardjono Tjahjadi, Sp.BS, Subsp. N-Vas, F. N-Onk, PhD, FICS, IFAANS—widely known as Dr. Joy—successfully performed head tumor removal in approximately 30 minutes while maintaining high standards of accuracy and patient safety.

30-Minute Head Tumor Surgery by Dr. Joy at Mandaya Royal Hospital Puri
The head tumor removal procedure performed by Dr. Joy at Mandaya Royal Hospital Puri took only around 30 minutes and was carried out using the awake surgery method. This technique allows patients to remain conscious during the procedure, enabling neurosurgeons to work with high precision while continuously monitoring neurological function in real time.
During the operation, the patient was able to communicate and interact with Dr. Joy, who served as the lead surgeon for the brain tumor removal. Once the tumor was successfully removed, Dr. Joy immediately showed the tumor to the patient as confirmation that the procedure had been completed effectively and according to plan.
Remarkably, once the surgery was completed, the patient was able to stand and walk without difficulty. The patient even stood beside Dr. Joy to share their experience undergoing awake surgery. The patient reported remaining fully conscious throughout the procedure, experiencing no pain, and being able to walk shortly after surgery.
