Importance:As new institutions incorporate transoral robotic surgery (TORS) into their everyday practice, it is helpful to have a timeline reference of expected goals to follow as their experience increases. This article evaluates a single tertiary care academic institution's experience with TORS for head and neck tumors and reports its 4-year learning curve.Objective: To evaluate a single institution's experience with TORS over a 4-year period and report treatment trends and clinical outcomes.Design: Prospective case study. Results: Significant decreases in operative time, length of intubation, and hospital stay were seen as TORS experience increased. Overall, the mean operative time decreased by 47% (group 4, 86 minutes; group 1, 183 minutes). Total mean intubation time decreased by 87% (group 1, 12.9 hours; group 4, 1.7 hours) and mean hospital stay decreased from 3.0 days to 1.4 days. There was not a significant difference between groups in number of cases unable to be performed robotically (7-9 per group), tumor stage (majority T1/T2), tumor subsite (majority oropharynx), positive margin status (2-5 per group), number of salvage cases performed (7-9 per group), and number of tracheostomies (2-4 per group) or feeding tubes (22-25 per group) required.
Conclusions and Relevance:This is the first multiyear prospective study to document a single institution's TORS experience over time and demonstrate particular areas of expected improvement as case number increases.
