Recognition of anatomical structures of the neck after an ultrasound training program for Universidad de Chile’s otorhinolaryngology residents

Abstract

Introduction: Surgeon-performed ultrasound is a valuable tool for real-time diagnosis. Its application can speed up the diagnostic and therapeutic process. Objective: To evaluate the performance in the recognition of neck structures after an ultrasound training program for otolaryngology residents, to evaluate the technique when performing ultrasound and to describe if some variables affect performance. Material and Methods: A total of 15 residents participated in the program that included theoretical and practical classes. Anatomical structures recognition and handling of the ultrasound equipment were evaluated applying a known skill assessment test. Scores were correlated with years of residency and medical experience and with previous ultrasound experience. Results: The scores obtained reflected a progressively significant improvement in ultrasound skills. In the first, second and third evaluation, the median scores were 15, 29 and 35 points, respectively. Statistically significant differences were observed in learning between the beginning and the end of the training for first- and second-year residents. There were no statistically significant differences in the scores given by different evaluators or between participants with and without prior ultrasound knowledge. Conclusion: This results highlight the effectiveness of a head and neck ultrasound training program to improve the skills and resident’s knowledge and support the idea of incorporating ultrasonography in the educational programs of otolaryngologists in Chile.
