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.

Overview / Goals and Objectives of Fellowship
The aim of this fellowship is to offer high quality training focusing on advanced rhinology and endoscopic skull-base surgery. It is our intention to provide training to individuals who will become leaders focusing on exemplary clinical care, quality improvement standards, research and education. The fellowship provides a focused rhinologic and skull base experience in a tertiary-care adult and pediatric academic environment. This fellowship emphasises inflammatory paranasal sinus disorders, revision sinus surgery, complex frontal and sphenoid sinus disease and minimally invasive approaches to the paranasal sinuses and skull base for treatment of pathologies including infection, optic nerve lesions, CSF leak management and resection of benign and malignant sinonasal neoplasms utilizing trans-nasal and trans-orbital endoscopic approaches.
The fellowship is based at Hamilton Health Sciences - HHS (McMaster University Medical Centre and Hamilton General Hospital). The fellow works with the rhinology/skull-base attending staff in the clinic and operating room. There are no set rotations, however the fellow assignments are arranged for participation in more complex revision sinus and skull base cases and rhinology focused clinics as well as combined skull bases/pituitary clinics. The fellow will also be expected to take part in on call duties as well as help in the provision of routine and more urgent care for inpatients and emergency department patients. These clinical opportunities may be modified to allow fulfillment of clinical, research and educational interests.
The weekly schedule mirrors the schedule of the attending rhinology service at HHS. On average, there are 1-2 days of OR and approximately 2-3 days of clinic. The remainder of available time is allocated to research, education or other clinical endeavours.
