Evaluation of Neurotoxin and Filler Injection Training in Otolaryngology Residency

Abstract

Introduction: Residency training courses are fundamental to an Otolaryngology (ENT) residency curriculum. Neurotoxin and filler injections have become common during ENT residency, and the outcomes of training courses have not been previously evaluated. We hypothesize that after participating in the course, resident knowledge, skill, and likelihood of using neurotoxin and filler injections in future practice will significantly improve. Materials and Methods: A prospective study was designed among ENT residents undergoing neurotoxin and filler injection educational training courses from April 2019 to November 2020. After the completion of the course and injections, residents completed a self-evaluation to assess their level of knowledge and skill level with neurotoxin and filler injections. Results: The mean number of neurotoxin and filler injections besides within the course was 1.67 and 0.33, whereas during the course was 3.39 (P = .008) and 1.39 (P = .0009), respectively. Resident knowledge, skill, and likelihood of using neurotoxin and filler injections in future practice all significantly improved (P < .05). This study found that a biannual training course for neurotoxin and injectable fillers was an effective strategy at improving resident knowledge, skill, and likelihood of use in future practice.
