Abstract: Objective To explore the application of external auditory canal model combined with traditional teaching method for improving the teaching quality. Methods All 50 refresher doctors of sun yat-sen university were divided into experiment group and control group. Experiment group added an extra practice of external auditory canal model. The differences between the two groups in practice and subjective evaluation were analyzed. Results The trarnees in experiment group was significantly less than the control group in terms of the times of touching the external auditory canal [(2.52±0.65) vs (3.76±0.93)], the times of teachers' help [1(1,2) vs 2(2,2.75)] and the time of completion[(18.62±3.09) vs (24.08±4.05)] (all P<0.05). The experiment group was better than the control group in operation proficiency [(7.92±0.76) vs (6.88±0.98)] and teaching method evaluation [(9.80±0.41) vs (7.96±0.98)](all P<0.05). Conclusions External auditory canal model combined with traditional teaching has obvious advantages in the training of endoscopic otologic surgery. As an efficient teaching tool, it plays an important role in the training of trainees.
