Mehmet Alpay Cal

Dr. Mehmet Alpay Cal is a neurosurgeon and spine specialist at Liv Hospital Ulus. He performs neuro-oncological surgery, complex spinal procedures, and pediatric neurosurgery. He also treats functional neurological disorders using stimulation and pump technologies. These technologies help manage movement and pain disorders.

Specialization and Surgical Focus

Dr. Cal treats various conditions affecting the brain and nervous system. His practice includes treating brain tumors, cerebral aneurysms, and arteriovenous malformations. He also addresses congenital issues such as craniostenosis and Chiari malformations.

The doctor performs several procedures:

• Deep brain stimulation (DBS) surgery – a procedure that uses implanted electrodes to treat movement disorders
• CyberKnife and Gamma Knife radiosurgery – non-invasive radiation treatments for tumors and lesions
• Surgical removal of brain tumors and cysts
• Scoliosis and spinal stenosis surgery
• Spinal cord stimulator (SCS) implantation – a device that sends electrical signals to the spinal cord to block pain
• Baclofen pump surgery for spasticity – an implanted device that delivers muscle relaxants directly to the spinal fluid
• Neurorrhaphy for peripheral nerve repair – a microsurgical technique to reconnect damaged nerves

Academic Research and Publications

Dr. Cal investigates laboratory markers and drug interactions in neurosurgery. His research covers cervical corpectomy techniques and analgesia for spine operations. He has authored multiple studies in international medical journals and examines antiepileptic drugs for brain tumor patients.
