          Abstract

          Transoral robotic surgery (TORS) has evolved into a common surgical modality used to treat primarily oropharyngeal malignant and benign pathologies. The single port Intuitive Surgical da Vinci surgical robotics system facilitates access to the hypopharynx and cervical esophagus. We aim to describe our approach and advantages of the technique.

          Abstract

          Transoral robotic surgery should be considered as a surgical approach for hypopharyngeal and cervical esophageal masses. The da Vinci single‐port (SP) robotic system conveys significant advantages in surgical dissection, exposure, and visualization.

          Single-port transoral robotic surgery hypopharyngectomy.

          Transoral robotic surgery (TORS) is an established treatment for many subsites of Head and Neck cancer. With the improved flexibility and access of the single-port (SP) robotic system, tumors within the distal upper aerodigestive tract can now be reached and successfully treated with all the published advantages of transoral endoscopic surgery. Here in we offer the first published surgical technique for SP TORS for resectable hypopharyngeal carcinoma. The video presented demonstrates many important aspects utilizing the enhanced robotic system, including adjustments of the semi-flexible endoscope and use of the third transoral surgical instrumentation. As previously reported, TORS hypopharyngectomy should be considered for resectable tumors to improve upon the deleterious effects of open surgical resection or chemoradiation therapy.

            Preoperative predictors of difficult hypopharyngeal exposure by retractor for transoral robotic surgery

            Introduction Transoral endoscopic surgeries provide excellent oncologic outcomes while preserving speech and swallowing ability. However, feasibility has been a major concern about transoral surgery. Therefore, ensuring visualization of the surgical field and sufficient working space is required. The aim of this study was to evaluate the parameters in the preoperative assessment that affect hypopharyngeal exposure. Methods Before transoral surgery, parameters regarding the patient’s neck and face such as modified Mallampati index, thyroid–mental distance (TMD), and ability to fully open the mouth were evaluated. Cephalometry and cervical spine radiography were performed preoperatively to evaluate the size of the mandible bone, mouth opening, and cervical spine extension. Mandibular bone parameters such as intergonion distance, mental–gonion distance, articulare–gonion distance, and aperture angle were measured. According to hypopharyngeal exposure using FKWO retractor, patients were divided into difficult hypopharyngeal exposure group (DHE) and non-difficult hypopharyngeal exposure group (non-DHE). Parameters were enrolled to evaluate the relationship between these parameters and DHE status. Results This study included 51 patients, 37 in the non-DHE group and 14 in the DHE group. On radiographic evaluation, there was a significant difference in the degree of cervical lordosis between non-DHE and DHE patients. A significantly higher proportion of DHE patients had a history of radiotherapy compared with non-DHE patients. Conclusion Patients with limited cervical extension and a history of previous radiotherapy might have difficult hypopharyngeal exposure during transoral surgery. This is the first report to suggest a classification system for hypopharyngeal exposure during transoral surgery.
