    Arnau Benet Cabero, MD, is an Assistant Professor in the Department of Otolaryngology – Head and Neck Surgery (OHNS) and in the Department of Neurological Surgery at the University of California, San Francisco. He is also the Director of the Skull Base and Cerebrovascular Laboratory at UCSF. He received his medical degree from the University of Barcelona in Spain and he completed his internship at the same institution, followed by a minimally invasive neurosurgery research fellowship at University of Pittsburgh Medical Center, Pennsylvania.

    Dr. Benet is an expert in skull base and cerebrovascular neurosurgery research. He combines a wide conception of all treatment options for complex lesions to maximize surgical efficiency while reducing morbidity. His ultimate goal of such research is to combine surgical experience with objective morphometric and anatomic analysis resulting from cadaveric dissection to optimize the current trends in the practice of Neurosurgery and OHNS.

    Dr. Benet is a member of the Cerebrovascular Section of the American Association of Neurological Surgeons and the Congress of Neurological Surgeons, and the American Association of Neurological Surgery.

    Skull base and cerebrovascular neurosurgery are complex and exciting areas that require high level of expertise combined with a wide conception of all treatment options for each particular lesion.
    Precise knowledge of the variety of treatment strategies available for a specific pathology is crucial to successfully remove a lesion with minimal morbidity and mortality for the patient.

    Enormous advances in surgical and endovascular treatment of both cerebrovascular and skull base lesions have been done in the past decades. Actual trends in skull base and cerebrovascular research include: a, descriptive studies about both different expansions of endoscopic endonasal routes and intricate surgical anatomy; b, morphometric comparison and analysis of diverse transcranial microsurgical approaches and c, a clinical approach to endonasal versus microsurgical treatment of midline skull base lesions.

    Although many authors have provided detailed descriptions of extended endoscopic endonasal and transcranial approaches for cranial base lesions, an anatomically, surgically and clinically oriented guideline to determine its indications is lacking in the actual literature.

    A comprehensive comparative study of treatment options for a selected landmark with clinical and surgical relevance can potentially optimize the practice of neurosurgery by providing recommendations based on objective statistical and descriptive integrated research.

    The main objective of the laboratory is to propose a comprehensive clinically, surgically and anatomically based guideline and rationale for treatment of the most challenging skull base and cerebrovascular lesions in a minimally invasive fashion. The ultimate goal of such research is to combine surgical experience with objective morphometric and anatomic analysis resulting from cadaveric dissection to optimize the current trends in the practice of Neurosurgery. For accomplishing this purpose a meticulous surgical simulation in the dissection laboratory together with constant experimentation for new surgical corridors are proposed.

    As a result of the anatomical and surgical sections of the research activity, different intricate anatomic regions and structures could require further study. Therefore, basic surgical anatomy research could be developed in parallel to either complement or detail the operative technique of several surgical approaches.

    Cerebrovascular surgery training with real time Blood-flow simulation is also a parallel developable option that the author has designed and tried in the past. This program could potentially benefit both cerebrovascular research and novel vascular neurosurgeons training. Therefore, the author considers this to be an excellent option for further development to complement the research activity in the laboratory.
