Traditional external surgical approaches have been used for the surgical management of the oropharyngeal and laryngeal tumors. Trans-oral robotic surgery allows surgeon to operate oropharyngeal and supraglottic tumors through the mouth with preservation of functions. The surgeons must be knowledgeable about the anatomy of the oral cavity and oropharynx medial to lateral perspective. In this article, we will describe the relevant inside out surgical anatomy and its clinical implications for trans-oral robotic surgery...

Transoral robotic surgery (TORS) has gained importance in head and neck surgery due to the possibility to visualize regions within the pharynx and larynx which are difficult to access. The success of transoral surgery depends on the exposure of the region of interest in order to allow visualization using a camera system. The Medrobotics Flex(®) Robotic System is a new flexible endoscopic system designed to overcome difficulties experienced in transoral surgery using other robotic systems with rigid endoscopes and instruments...

Nasogastric (NG) intubation is one of the most commonly performed clinical procedures. Real-time localization and tracking of the NG tube passage at the larynx region into the esophagus is crucial for safety, but is lacking in current practice. In this paper, we present the design, analysis and evaluation of a non-invasive real-time localization system using passive magnetic tracking techniques to improve efficacy of the clinical NG intubation process. By embedding a small permanent magnet at the insertion tip of the NG tube, a wearable system containing embedded sensors around the neck can determine the absolute position of the NG tube inside the body in real-time to assist in insertion...

Transoral robotic surgery (TORS) is being increasingly used in the treatment of head and neck cancer and we wanted to determine the feasibility of predicting TORS access using cephalometric measurements obtained from preoperative imaging. 20 cephalometric measurements were obtained from imaging on 31 TORS base of tongue (BOT) resections and compared to adequacy of exposure. Three measurements were found to be significantly different between the restricted and adequate exposure groups. Distances from posterior pharyngeal wall (PPW) to hyoid, PPW to soft palate and epiglottis to vertical laryngeal angle were all statistically different between the two groups...

BACKGROUND: The laryngeal schwannoma is a rare benign tumor of the larynx, most frequently found in the aryepiglottic fold, which can be rather bulky when diagnosed. METHODS: We present a primary transoral robotic surgery (TORS) for a laryngeal schwannoma and highlight the advantages of the robotic assistance. RESULTS: Thanks to the high-definition 3D dynamic vision and an improved freedom of movement, it is possible to accurately accomplish surgical tasks that previously were much more complex or even unfeasible through a minimally invasive approach, potentially minimizing the surgical damage...
