“…Consequently, this technique's applicability should be limited to lesions of the tongue. Newer robotic technologies are emerging with narrow and flexible designs [9]. Such devices could potentially obviate the need for suspension apparatuses and negate the limitations of ''standard'' TORS approaches outlined here.…”

This study describes a novel exposure technique for base of tongue trans-oral robotic surgery (BOT TORS) and early experience with it. The technique discussed involves placement of a suture through the mobile tongue with distraction and suspension of the tongue to the operating table. TORS is then performed per previously described techniques. In our series, 13 patients with either benign or malignant mass lesions involving the tongue base were treated with TORS at a tertiary academic medical center. We reviewed the rates of adequate exposure, console time, adequacy of resection (in malignant cases), complication rates, and costs associated with this technique. In our series, adequate exposure was achieved in 92.3 % of patients. Mean console time was 36 min. Negative surgical margins were achieved in all cancer resections. Five minor complications (tongue lacerations) were observed. Per-case cost attributable to this technique is $3.81. We conclude that BOT TORS is feasible without the use of a mouth prop. Operative times are consistent with those reported by centers that routinely use mouth props for BOT TORS. This technique does not appear to compromise margin adequacy during oncologic resections. Its use may result in a significant cost savings when compared to the FK and other similar retractors.

“…The robot's size is also diversified ranging from 2.4mm 82 to 23mm 95 . Due to their lightweight, simplicity, biocompatibility, safety, and flexibility cable systems have been used for various surgical robotic systems such as Da Vinci surgical system 23,40,77 , endoscopes 22,23 , Medrobotics Flex System 98,164,169 , MASTER system 35,154 , and Viacath system 2 . The following contents will analyse the conceptual designs, modelling, control problems, advantages, and disadvantages of cable actuationdriven surgical robots.…”

“…The Medrobotics Flex Ò Robotic System (Medrobotics Corp., Raynham, MA, USA) was designed to overcome these limitations and consists of a highly flexible endoscope with a snakelike advancement mechanism allowing nonlinear positioning. Accessory channels allow the insertion of flexible tools [8]. In this context, optimal exposure of the region of interest using a suitable retractor remains crucial for visualization and access through the robotic system.…”

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. In this article, we describe the first use of the Medrobotics Flex(®) Retractor in humans, a retractor designed for advanced transoral procedures. We report our experience in 11 patients requiring surgery of the oropharynx, hypopharynx, and supraglottic larynx. In all cases, we successfully exposed all targeted surgical regions. We experienced easy handling of the retractor alongside comparable positioning times and no observed mucosal damage.
