PURPOSE: The purpose of this study was to determine if the use of the FIREFLY imaging system could be an asset in transoral robotic surgery (TORS) for oropharyngeal squamous cell carcinoma (OPSCC). The system uses indocyanine green dye (ICG), which fluoresces when illuminated by near-infrared light from the Da Vinci robot. The system may improve visualization of tumor margins, highlight important vascular structures, and help identify the location of tumors and unknown primary head and neck cancers...

BACKGROUND: Head and neck surgery is not often considered a risk factor for intestinal ileus and small bowel obstruction. However, many of these patients may have had prior abdominal surgery, a known risk factor for small bowel obstruction, and may be at risk for bowel obstruction after a surgical procedure of the head and neck. METHODS: We present a case describing a patient who, after undergoing transoral robotic surgery, experienced delayed postoperative ileus and eventual small bowel obstruction requiring exploratory laparotomy and bowel resection...

Hypopharyngeal cysts are very uncommon pathology. They are presented in adult people over 60 years. Although oncocytic cysts are benign tumors, an incomplete resection causes recurrence. The symptoms are not specific, but the more frequent are dyspnea and foreign body sensation upon swallowing. Diagnosis usually is under general anesthesia during intubation. A flexible fiberoptic laryngoscopy could be insufficient; the trumpet maneuver during this examination can reveled occult cysts. To perform a total resection, the surgeon must have a complete exposition of the operative field...

Importance: In recent years, transoral robotic surgery (TORS) has emerged as a useful treatment for oropharyngeal squamous cell carcinoma (OPSCC). In appropriately selected patients, the use of TORS may allow avoidance of adjuvant chemotherapy and/or radiotherapy, thereby avoiding the long-term adverse effects of these therapies. Objective: To compare functional speech, swallowing, and quality-of-life outcomes longitudinally between those undergoing TORS only and those undergoing TORS and adjuvant radiotherapy (TORS+RT) or TORS and chemoradiotherapy (TORS+CRT)...

PURPOSE: Flexible surgical robot can work in confined and complex environments, which makes it a good option for minimally invasive surgery. In order to utilize flexible manipulators in complicated and constrained surgical environments, it is of great significance to monitor the position and shape of the curvilinear manipulator in real time during the procedures. In this paper, we propose a magnetic tracking-based planar shape sensing and navigation system for flexible surgical robots in the transoral surgery...

The transoral robotic oropharyngectomy surgical technique was initially described for resection of small stage T1 or T2 lesions and the surgical defect is usually allowed to heal by secondary intention. We propose a refined surgical approach adapted to more complex situations such as salvage surgery and surgery in an irradiated field, based on previous experience in open approaches for oropharyngeal cancer. Via a combined cervical-transoral approach, we perform en bloc resection of the parapharyngeal space combined with transoral robotic lateral oropharyngectomy...

Thyroid surgery has evolved throughout the years from being one of the most dangerous surgeries to becoming one of the safest surgical procedures performed today. Recent technologic innovations have allowed surgeons to remove the thyroid gland from a remote site while avoiding visible neck scars. There are many endoscopic approaches for thyroidectomy. The most common cervical approach is the minimally invasive video-assisted technique developed by Miccoli et al. The robotic transaxillary and axillary breast approaches avoid a neck scar and have been demonstrated to be safe and effective in international populations...

BACKGROUND: Endoscopic-assisted transoral surgery, including transoral robotic surgery for metastatic retropharyngeal lymph node (RPN) from well-differentiated thyroid cancer, has been reported to reduce the complications resulting from transcervical and transmandibular approaches. However, the narrow working space and difficulty identifying RPN are problematic. To solve these issues, several studies have used intraoperative ultrasound in endoscopic-assisted transoral surgery. However, the type of ultrasonography suitable for this purpose remains unclear...
