Medical Intrests

• Pediatric Neurosurgery

Skull Aesthetics
 

Skull reshaping, also known as skull reshaping, can be done using many different methods. Cranioplasty surgery and plastic surgery that involves placing a specially produced 3D implant into the skull provide the most accurate results.

Later, I had the chance to work as a clinical research fellow (observer doctor) with Prof. Dr. Mustafa Başkaya at the University of Wisconsin in the USA. After returning from the USA, I worked at Okmeydanı Education and Research Hospital for another four years and started working as a specialist doctor at Medicalpark Bahçelievler Hospital in 2020.

With the excitement of transferring my experiences to future generations, I simultaneously continue my academic duty at Altınbaş University
