Study summary

The purpose of this study is to conduct a pilot single-arm to assess transoral robotic surgery (TORS) for oral and laryngopharyngeal benign and malignant lesions using the Da Vinci Robotic Surgical System.

Read the detailed description

Patients are going to be evaluated in their usual regular clinical follow ups starting with preoperative first visit, 3 weeks, 3 months and 6 months postoperatively with a Quality of Life survey (Head and Neck Cancer Inventory, HNCI-QOLQ).

What researchers measure

Primary outcomes

  1. The Number and Percent of All Evaluable Patients Who Have Successfully Undergone TORS at Each Interim Analysis.

    In order to evaluate the feasibility of TORS, the investigators will report the number and percent of all evaluable patients who have successfully undergone TORS at each interim analysis

    Time frame: At time of surgery, lasting up to 3 hours. Assessed for up to 6 months

Secondary outcomes

  1. Operative Time

    The total operative times include the induction of and emergence from anesthesia, the TORS procedure, plus any adjunct procedures (eg, neck dissections) performed during the same operation.

    Time frame: At time of surgery, up to 3 hours

  2. Number of Participants With Blood Loss and Complications

    Time frame: 6 months

  3. Average Time to Set up and Perform Procedures

    This outcome is to identify the learning curve for TORS by measuring the efficiency of the surgeon who performs the procedures.

    Time frame: At time of surgery, up to 3 hours

  4. Number of Correctly Predicted Success of TORS Preoperatively

    This outcome is to identify the learning curve for TORS by measuring the accuracy of the surgeon who performs the procedures.

    Time frame: preoperative

  5. QOL

    Quality of life (QOL) of the patients undergoing TORS will be measures. The score range is 0-100 with higher scores denoting better outcome.

    Time frame: 6 months
