My name is Ronald Hoffman. I'm a physician. My area of expertise is diseases of the ear. That is known as otology and neurotology. In this series of videos, I am going to try to teach you, in as close to layman's terms as we can get, about the anatomy of the ear which means the structure of the ear, the physiology of the ear, which means the function of the ear, the diseases that affect the ear, and how those diseases might be treated. And in particular, how you might help take control of your own health care, knowing what you can do on your own, and when you have to seek medical advice, and how I might help you better understand the disease that you have.
