As part of the Medical Scholars Program, you will quickly be placed in a high-intensity environment with head and neck surgeons. While it is not required that you have any knowledge of ENT, your experience will be made much more productive if you are able to ask insightful questions that reflect an understanding of the basic concepts.
The book linked below is a useful resource for medical students and may therefore be too complex for you at this level. However, it is highly recommended that you read as much as you can prior to starting the program. Look up terms you do not know so that you start to build your medical vocabulary. OHNI does expect you to have a foundation of knowledge upon which to build.
