Abstract: Objective To analyze the course design and training outcomes of cochlear implant special training course, and to explore the training methods for otology microsurgeons to master cochlear implant technology. Methods Among the 24 students, 33% are senior (8/24), 17% are deputy senior (4/24), 50% are intermediate(12/24), In terms of Degree distribution,58% are PhD, 25% are master and 17% are bachelor. Totally 92%(22/24) of the trainees believed that the training was very helpful for surgery, and but 8%(2/24) of them thought the outcome of the training was not so helpful. The most helpful part of the training is the facial nerve recess approach technology. The highest score for participating in the class was the training method of cochlear implant surgery, which could be improved constantly in accordance with the training method when back to their own hospitals. As for the organization and course setting, the teaching method of step by step scored the highest for the, followed by the course setting including the facial nerve recess approach, subtotal petrosectomy and transotic approach. Conclusions The teaching methods of step by step, centralized comments and discussion helps trainees to understand the cochlear implant technology quickly.
