Otorhynolaryngology image as supplementary teaching material

Introduction and objective: Using videos as complementary teaching material can replace part of the teaching hours and be helpful in acquisition of knowledge in Otorhinolaryngology. To evaluate this alternative the impact of visualizations of 4 videos on performance in specific questions of the Otorhinolaryngology exam will be analyzed and students' perception of these videos will be evaluated.Method: Quasi-experimental analytical study, conducted in 213 students of Otolaryngology of Autonomous University of Madrid divided in two groups (intervention and control). Differences between intervention and control group were analyzed using the chi-square test or the exact Fisher test (p value<0.05 statistically significant). Feedback from students on the videos was collected.Results: The total number of video visualizations was 883. Significant differences were observed (p < 0.01) on performance in question "ear 1" with 27.78% of success rate of the experimental group versus 7.50% of the control group, and in question "neck 2" with 38.89% of success rate of the experimental group compared to 81.80% of the control group. Most opinions about the videos (94.87%) were positive.Discussion and conclusions: No significant impact on performance was found, easy access to videos and positive feedback from students highlight its usefulness as a complementary teaching material to classes in Otorhinolaryngology.
