Abstract
Introduction: Transoral robotic surgery (TORS) for head and neck cancer treatment is not approved in Japan. We have stared TORS as a clinical trial from August 2011. We presented the result of simulation surgery previously. But larynx and hypopharynx couldn't be exposed adequately because of instrument limitation. In June 2013, a new FKWO retractor become available.
Aim: We attempted whether larynx and hypopharynx could be exposed and whether 8mm EndoWrist could be handled smoothly in these areas.
Results: We were able to clearly expose these areas. However the movement of EndoWrist was limited at lateral side of hypopharynx and ventral side of larynx.
Conclusion: The exposure of TORS was improved but cases of larynxand hypopharynx should carefully be selected.
