Eric J. Dierks, M.D., D.M.D., F.A.C.S.
Dr. Eric Dierks was a full-time medical school faculty member at the University of Texas Southwestern Medical Center in Dallas before moving to Portland to join Dr. Potter to form the Head and Neck Surgical Associates (HNSA). He received his medical and dental degrees from the University of Louisville and completed his residency in oral and maxillofacial surgery at the Christiana Medical Center of Delaware and his otolaryngology/head and neck surgery residency at U.T. Southwestern (Parkland Memorial Hospital). He is one of about a dozen American surgeons who are board-certified in otolaryngology as well as oral and maxillofacial surgery.
His surgical practice focuses on what he calls “the 4 T’s”:
TUMOR: Dr. Dierks’ career has focused upon advancing the surgical treatment of cancer and benign tumors of the mouth, throat, face, sinuses, salivary glands and other sites within the head and neck, as well as associated reconstructive surgery. He is an innovator of several of the surgical techniques that are in general use today. He was among the first surgeons on the west coast to use the surgical robot to remove cancer from the mouth and throat. He is a recognized expert in minimally invasive surgery of the parotid and other salivary glands.
TRAUMA: Along with the other surgeons of the HNSA, Dr. Dierks is actively involved in the highly acclaimed Level I trauma program at Legacy Emanuel Hospital and also frequently receives craniomaxillofacial trauma patients in transfer from other hospitals, both regionally and from afar. He also performs a significant amount of secondary reconstructive surgery on trauma patients. He is frequently consulted regarding facial injuries among local and regional professional athletes.
TITANIUM: Dr. Dierks is internationally known for his innovative use of dental implants for complex oral and facial defects. He works with dentists and prosthodontists throughout the Pacific Northwest and beyond to achieve successful and cost-effective dental implant rehabilitation for his patients. In addition to routine implants, he is frequently referred patients for zygomatic implants and for other complex implant cases.
TEETH: Dr. Dierks is actively involved in the practice of general oral surgery including wisdom tooth removal under IV general anesthesia. The design of the HNSA facility and the expertise of its staff make it the safest environment for this type of outpatient surgery. It is no surprise that many regional physicians and dentists turn to the HNSA for the oral surgical care of their family members.
Of course, Dr. Dierks is involved in many other areas of surgery besides the 4 T’s, including primary and secondary cleft lip/palate surgery and reconstructive surgery of the trachea.
Like the other surgeons of the HNSA, Dr. Dierks is actively involved in the training of fellows in head and neck oncologic surgery, as well as oral and maxillofacial surgery residents from Oregon Health & Science University and the University of Washington. Dr. Dierks has lectured nationally and internationally and has been invited to teach surgery in India, Europe, Africa, Australia, and the Middle East. In addition to providing outstanding service to his patients from the Portland area, he regularly sees patients that travel from other parts of North America and beyond. Dr. Dierks has published over one hundred scientific papers and textbook chapters. He has been interviewed on numerous American and foreign television programs including 20/20, Good Morning America, ABC Nightline, The Rachael Ray Show, 60 Minutes Australia, RTL German News Television and Japanese news TV. He is frequently listed in Portland Monthly Magazine’s annual “Top Docs” dental issue in oral and maxillofacial surgery and in its medical issue in otolaryngology.
Before he was a doctor, Eric Dierks worked his way through college as an auto mechanic, and he still turns a wrench from time to time on his old cars. He remains interested in automotive design and technology. He is married and has a grown daughter and a teenage son.
