● Responding to the increased familiarity with endonasal endoscopic skull base surgery, we have modified the program to start at a higher level of expertise, and to promote discussions related to treatment algorithms of specific diseases ● However, we recognize the value of refreshing basic concepts; and that our course caters to participants with a variety of levels of training and experience ● Therefore, we will provide the participants with a series of video-lectures and video-prosections to fulfill these needs (Pre-Course) ● This video-lecture series will allow the participants to enjoy the benefits of both a traditional lecture-style course based on anatomic and technical concepts, and a course with a new interactive format emphasizing decision-making and disease-oriented discussions. Participants will in fact enroll in two courses, a home study course and the hands-on course without additional costs ●
