Skull Base Fellowship Registry

The membership of the North American Skull Base Society (NASBS) is a tremendous resource for the training of fellows, who are the future of the development of our specialty. The society has developed a registry of skull base fellowships that are offered by the society membership.

The society recognizes that we are a diverse and multidisciplinary group comprised of several different specialties, all of whom have significant interest and focus in the management of skull base neoplasia. Likewise, the nature and character of the various fellowships will represent and reflect their differences. In addition, we recognize that there will be variation between individual fellowship experiences resulting from the differences in the preceptor’s approaches and practices.

To post a Fellowship, please go to the Fellowship Registry Entry Form. You must be a member of NASBS to add a Fellowship to the Registry.
To edit an entry, please log in under the Member credentials used to add the entry to the registry and make edits to the listing.

To apply for Fellowship training, please contact the program directly.
If you need assistance or have questions, please contact the NASBS office at [email protected].

Additional Features of the Fellowship

This fellowship is a comprehensive 1-year fellowship, encompassing the full spectrum of skull base and complex cranial surgery from surgical approaches and nuances to interdisciplinary management of patients, as well as anatomical and clinical research. The department's high clinical volume and expertise creates an ideal combination of supervision and autonomy, preparing fellows for an independent academic career in skull base surgery. Under the direction of Aclan Dogan, MD, one of the leading skull base surgeons in the world, the clinical service is extremely busy and productive. Over 400 craniotomies for tumors and vascular disease, and over 120 transphenoidal pituitary surgery procedures are performed each year. Olabisi Sanusi, MD (a past Skull Base Fellow) offers the fellow opportunity to be active in the endoscopic skull base surgery service. Maria Fleseriu, MD, an internationally recognized neuroendocrinologist specializing in pituitary disease and Director of the NW Pituitary Center at OHSU provides an opportunity to further neuroendocrine education.
