Objectives: (1) To compare perioperative outcomes and overall survival of patients with oropharyngeal salivary gland malignancies (OPSGMs) treated with transoral robotic surgery (TORS) versus other approaches. (2) To identify clinical factors associated with a robotic surgical approach. Study Design: Retrospective analysis of the National Cancer Database (NCDB). Setting: NCDB. Methods: Data obtained from the NCDB were analyzed between 2010 and 2017 for patients with T1-T4a OPSGMs without distant metastases treated surgically. Patients were stratified by surgical approach (TORS vs nonrobotic), and clinicopathologic factors were compared with the t test or chi-square test for continuous or categorical variables, respectively. Overall survival was analyzed by patient demographics and clinical factors according to Kaplan-Meier and Cox proportional hazards models. Factors associated with TORS were assessed with logistic regression. Results: A total of 785 patients were analyzed. A non–soft palate primary site (odds ratio, 12.9; 95% CI, 6.6-25.2) and treatment at an academic facility (odds ratio, 2.0; 95% CI, 1.2-3.5) were independently associated with TORS. There were no significant differences in the positive margin rate, 30-day mortality, or overall survival between the groups. The 30-day unplanned readmission rate was higher in patients treated with TORS versus nonrobotic resections (5.8% vs 1.7%, P =.0004). When stratified by tumor subsite, there was a significant decrease in hospital length of stay in patients with tongue base tumors undergoing TORS versus nonrobotic resections (P =.029). Conclusion: This study suggests that TORS may be a viable treatment modality for appropriately selected patients with OPSGM.
