<jats:sec><jats:title>Importance</jats:title><jats:p> Ultrasound-guided fine-needle aspiration biopsies (UGFNA) play a crucial role in the diagnosis of thyroid nodules. There are two techniques for performing an UGFNA: short-axis technique and long-axis technique. There is sparsity in the literature regarding the differences between these two techniques. </jats:p></jats:sec><jats:sec><jats:title>Objective</jats:title><jats:p> To compare the efficiency between long-axis and short-axis thyroid UGFNA techniques in trainees. Our secondary outcomes were to define the comfort level and learning curves of trainees. </jats:p></jats:sec><jats:sec><jats:title>Design</jats:title><jats:p> A longitudinal prospective cohort study, completed from December 2018 to November 2019, using the Blue Phantom Thyroid Model© for UGFNA. Face and construct validity of the model were verified. Residents completed UGFNA on an assigned nodule using both long-axis and short-axis techniques, the order of which was sequentially allocated. The rate and time to successful biopsy were obtained for both techniques. Biopsy attempts were repeated to establish learning curves. </jats:p></jats:sec><jats:sec><jats:title>Setting</jats:title><jats:p> Single-center study. </jats:p></jats:sec><jats:sec><jats:title>Participants</jats:title><jats:p> Fourteen Otolaryngology—Head & Neck Surgery residents at the University of Toronto. </jats:p></jats:sec><jats:sec><jats:title>Main outcome measure</jats:title><jats:p> Biopsy success and efficiency for novice learners completing UGFNA on a simulated thyroid model using long-axis and short-axis techniques. </jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p> A trend towards higher odds of successful biopsy using the long-axis technique with no difference in procedure duration was observed (OR = 2.2, p = 0.095, CI = 0.87–5.39). Learning curve graphs appeared heterogenous according to trainee level. Trainees found the long-axis technique easier to perform (10/14, 71%), and the simulator valuable for learning (12/14, 86%). </jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p> Thyroid UGFNA using the long-axis technique may have an increased success rate and is generally favored by trainees for being easier to perform. Thyroid simulators have the potential to increase learner comfort and efficiency with UGFNA. </jats:p></jats:sec><jats:sec><jats:title>Graphical Abstract</jats:title><jats:p> </jats:p></jats:sec>
