Arnau Benet MD

Assistant Professor of Neurological Surgery and Otolaryngology

Director, Skull Base and Cerebrovascular Laboratory









Dr. Arnau Benet is director and principal investigator of the Skull Base and Cerebrovascular Laboratory. He is specialized in minimally invasive surgical research in neurosurgery, otolaryngology, and head and neck surgery. Dr. Benet has designed a surgical simulation method to accurately recreate operative scenarios in the laboratory. His laboratory investigations study surgical anatomy of microsurgical and endoscopic approaches to brain tumors and cerebrovascular lesions. He uses cutting-edge technology to compare approaches and design novel surgical trajectories. Dr. Benet has designed a novel method for surgical simulation of challenging brain aneurysm surgery that includes 3D modeling and printing of aneurysm replicas from patients. His clinical research includes surgical outcomes and efficiency in neurosurgery and otolaryngology. His main research goals are to design novel minimally invasive surgical strategies for treatment of complex brain lesions.

Dr. Benet is expert in 3D surgical anatomy. His educational impact includes interactive 3D lectures on surgical anatomy to neurosurgery and otolaryngology residents and national and international conferences. He also teaches anatomy in the school of medicine. His main educational objective is to increase surgical safety by raising awareness of the critical anatomic structures encountered in the neurosurgical and otolaryngology procedures.
