Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 33 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Prospective, Multicenter Investigation of the da Vinci® SP™ Surgical System in TORS Procedures for Resection of Malignant Tumors
Actual Study Start Date : April 17, 2017
Actual Primary Completion Date : November 14, 2017
Actual Study Completion Date : December 26, 2017

Arm Intervention/treatment
Experimental: Transoral robotic surgery Device: Transoral robotic surgery
Transoral robotic surgery for T1 & T2 oropharyngeal cancers

Primary Outcome Measures :
  1. Performance [ Time Frame: Intraoperative ]
    Performance defined as the conversion to an open approach required to complete the procedure

  2. Number of subjects with device-related serious adverse events [ Time Frame: Intraoperative through 7 weeks post-operative ]
    Safety is determined by measuring the number of subjects that experience device-related serious adverse events

Secondary Outcome Measures :
  1. Positive surgical margin [ Time Frame: Through14-days postoperatively ]
    Rate of final positive surgical margins confirmed by pathology
