BACKGROUND: Animation technology is invading the field of surgical training, especially in otolaryngology. This study has been conducted to measure the impact of the animation technology on the surgical performance of the junior trainees on the cadaveric dissection context, by identifying the ability of the residents to identify the important landmarks during cadaveric dissection mastoidectomy.
METHODS: Group of fourteen trainees in the third year of their residency program was divided randomly into two subgroups: group I as the experimental group and the group II as the comparison one. The study was conducted only after informed detailed consent was taken from all participants and the study proposal had been approved by the ethical committee of the University of South Wales. The experimental subgroup, which included five males and two females, has received four sessions of animation training on a temporal bone simulator in addition to their official ear surgery training. The comparison subgroup that included six males and a female has received the official training only.
RESULTS: Statistical analysis, using Statistical Package for the Social Sciences (SPSS), revealed that animation has enhanced the surgical training significantly. It has improved the surgical skills of identification of the important landmarks of the mastoidectomy namely identification sigmoid sinus, sino-dural angle, facial nerve and chorda tympani and identification of epitympanic anatomy to supratubal recess. It has enhanced the ability of the trainee to expose the short process of incus atrumatically. However, there was insignificant difference regarding the ability of to define cephalic edge digastric muscle and similarly there was statistically insignificant difference between both groups regarding identification and definition of tegmen.
CONCLUSIONS: The applied anatomy based surgical skills improved in a statistically significant pattern among the experimental group. So that it can be said that the animation technology can decrease the incidence of intra- and postoperative.
