A large, publicly available CV model fine\u2010tuned on endoscopic surgical video in collaboration with Surgical Data Science Collective (SDSC) was used for frame\u2010by\u2010frame detection of 14 different surgical instruments. Tool usage was depicted across different surgical phases of EEA. Dice\u2010S\u00f8rensen Similarity Coefficients (DICE) were used to identify similarities between tool motion patterns across patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Ten patients (5 male, 5 female, ages 52.1\u2009\u00b1\u200913.8 years) were included, with over 35\u2009h of video footage analyzed encompassing over 1.9 million individual frames. The sellar phase accounted for the majority of the analyzed frames. Within the sellar phase, the most frequently identified tools included suction (661,785), drill (138,031), Rhoton dissector (116,823), and cotton patties (105,038). Overall, DICE with higher frequency use exhibited substantially increased DICE scores: 0.52 for drill, 0.63 for Rhoton dissector, 0.67 for cotton patties, and 0.74 for suction.<\/jats:p>\n
