Dr. Jeffrey R. Janus is currently the Chair of the Department of Otolaryngology at Mayo Clinic in Jacksonville, Florida. He is a board certified, fellowship trained, Head and Neck Oncologic and Reconstructive Surgeon. Dr. Janus trained at the University of Florida College of Medicine in Gainesville, Florida where he received entrance into the Junior Honors Medical Program, combining the last year of undergraduate training and the first year of medical school.

Dr. Janus's interests include:

  • Salivary tumor (Parotid Gland) Surgery with special focus on postoperative facial nerve function and aesthetics
  • Removal and reconstruction of Head and Neck Cancers with concentration on restoration of pre-morbid form and function. These cases are often done with preoperative 3D planning and 3D printing of patient specific tools.
  • Endocrine Surgery — removal of thyroid and parathyroid tumors with consideration of voice function
  • Robotic Surgery — the use of the surgical robot to remove tumors of the throat (oropharynx) and voice box (larynx)
  • Multidisciplinary Head and Neck Cancer Clinic — this is a group of Head and Neck Surgeons, Radiation Oncologists, Medical Oncologists, Pathologists, Radiologists, and other staff who meet regularly at Mayo Clinic Florida to review complex cases and compose multidisciplinary treatment plans.
  • Minimally invasive (endoscopic) approaches to the skull base and pituitary gland

In addition to his clinical activities, Dr. Janus is active in research and education, providing mentorship to residents and fellows.
