Objectives: Hyolaryngeal movement during swallowing is essential to airway protection and bolus clearance. Although palpation is widely used to evaluate hyolaryngeal motion, insufficient accuracy has been reported. The Bando Stretchable Strain Sensor for Swallowing (B4S™) was developed to capture hyolaryngeal elevation and display it as waveforms. This study compared laryngeal movement time detected by the B4S™ with laryngeal movement time measured by videofluoroscopy (VF). Methods: Participants were 20 patients without swallowing difficulty (10 men, 10 women; age 30...

Oropharyngeal cancer requiring combined resection of the soft palate is relatively out of indication for transoral robotic surgery (TORS) due to postoperative functional problems. We report the case of a patient with oropharyngeal cancer in which half of the soft palate was resected, and good function was maintained using the Gehanno method, polyglycolic acid (PGA) sheet and fibrin glue. The patient was a woman in her 50 s with oropharyngeal squamous cell carcinoma (p16-positive, T2N1M0 stage I). TORS and right neck dissection were performed the same day...

The use of robotics in head and neck surgery has drastically increased over the past two decades. Transoral robotic surgery has revolutionized the surgical approach to the upper aerodigestive tract including the oropharynx and supraglottic larynx. The expanded use and improving technology of robotics have allowed for new approaches in both the ablative and reconstructive aspects of head and neck surgery. Here, we discuss the recent updates in robotics in head and neck surgery and future directions the field may turn...

A 63-year-old male with a history of chronic obstructive pulmonary disease and squamous cell carcinoma of the larynx status-post laryngectomy and tracheostomy presented for a robotic-assisted right upper lobectomy for neoplasm excision. On physical examination, he was noted to have moderate hypoxia with an SpO2  of 93% on room air. In order to facilitate potential apneic oxygen insufflation and continuous positive airway pressure in the operative lung, a traditional left-sided 35-French double-lumen endobronchial tube was placed through his tracheostomy, and utilized to facilitate lung separation and to improve surgical manipulation...

OBJECTIVES: To describe the inside out surgical anatomy of the superior laryngeal artery and to resolve the ambiguities in the nomenclature of its main branches. STUDY DESIGN: Endoscopic dissection of the superior laryngeal artery in the paraglottic space of larynges of fresh frozen cadavers and a review of the literature. SETTING: A center for anatomy encompassing facilities for latex injection into the cervical arteries of human donor bodies and a laryngeal dissection station equipped with a video-guided endoscope and a 3-dimensional camera...

Transoral robotic surgery (TORS) is a growing field in the treatment of head and neck cancers. Its benefits have been proven in the treatment of oropharynx HPV-positive squamous cell carcinoma, replacing chemoradiation as primary treatment of early-stage cancers or reducing the required radiation dosage, leading to improved functional outcomes without compromising oncological outcomes. There is also interest in the application of TORS for larynx cancer with the hope of achieving similar outcomes to replace open surgery or radiation treatments...

PURPOSE: To define if positive and close surgical margins are associated to worse prognosis in patients who underwent transoral robotic surgery (TORS) after neoadjuvant chemotherapy (NCT). METHODS: A retrospective cohort study was carried out at a tertiary referral center. The primary outcome was local-regional control (LRC), and the results were summarized with hazard ratios (HR) and 95% confidence intervals (CIs). RESULTS: A total of 308 patients (median age: 62...

OBJECTIVES: To analyze the oncological and functional outcomes of patients with stage III-IV laryngo-hypopharyngeal cancer who underwent neoadjuvant chemotherapy (NAC) with subsequent transoral robotic surgery (TORS). MATERIALS AND METHODS: A single-center retrospective cohort study included a total of 100 patients (median age of 67.0) affected by stage III-IV supraglottic or hypopharyngeal cancer. All patients underwent NAC followed by TORS and risk-adjusted adjuvant therapy...

Minimally invasive surgery is a growing field in surgical oncology. After acquiring its first Food and Drug Administration approval in 2009 for T1-T2 malignancies of the oral cavity, oropharynx, and larynx, transoral robotic surgery (TORS) has gained popularity thanks to its wristed instruments and magnified three-dimensional view, enhancing surgical comfort in remote-access areas. Its indications are expanding in the treatment of head and neck cancer, i.e., resection of tumors of the larynx, hypopharynx, or parapharyngeal space...

Hypopharyngeal cancer is usually diagnosed at an advanced stage and is associated with a high risk of recurrence and poor survival rates. Although they differ greatly in terms of prognosis, hypopharyngeal cancers are usually treated together with laryngeal cancers in clinical trials. Therefore, there are very few studies that focus specifically on patients with hypopharyngeal carcinoma. As a result, the therapeutic management of these patients is highly debated, and their clinical outcomes are poorly reported...

This paper reports the design, construction, and experimental validation of a novel hand-held robot for in-office laser surgery of the vocal folds. In-office endoscopic laser surgery is an emerging trend in Laryngology: It promises to deliver the same patient outcomes of traditional surgical treatment (i.e., in the operating room), at a fraction of the cost. Unfortunately, office procedures can be challenging to perform; the optical fibers used for laser delivery can only emit light forward in a line-of-sight fashion, which severely limits anatomical access...

OBJECTIVE: Soft tissue necrosis (STN) can occur after transoral robotic surgery (TORS) with radiation therapy (RT). We investigated the usefulness of local flap reconstruction for preventing STN after TORS in patients with tonsillar cancer. METHODS: This case-control study retrospectively reviewed clinicopathological data of patients who underwent TORS for tonsillar cancer at a tertiary referral center. The incidence of STN was compared in patients who underwent secondary intention healing or local flap reconstruction, and factors predicting STN were identified...
