The management of cervical lymph node metastasis remains a crucial component of the treatment of head and neck cancers. However, the proper management of clinical N 0 cases with early-stage oral squamous cell carcinoma (OSCC) remains undefined. In the advent of minimally invasive techniques in the 1980s, these techniques have gained popularity among numerous surgeons in all fields of surgery. Although there are no randomized controlled trial data comparing the outcomes of minimally invasive techniques (endoscopically assisted selective neck dissection (SND), robot-assisted SND) with conventional techniques, encouraging evidence from several studies suggests that both endoscopically assisted SND and robot-assisted SND are safe, minimally invasive techniques with achieved short-term oncologic outcomes and can reach a better cosmetic outcome than conventional SND...

There has been a significant increase in concern towards improving aesthetic and functional outcomes without compromising the oncologic effectiveness in head and neck surgery. The aim of the current study is to assess the feasibility and oncological outcome of the retroauricular approach for endoscopic and robot-assisted selective neck dissection (SND) for oral cancer in comparison with the conventional SND. A retrospective single institute cohort study was designed. Patients undergoing an SND for oral cavity carcinoma were included and allocated into two groups: (1) retroauricular approach group for endoscopic-assisted or robot-assisted SND or (2) transcervical approach group for the conventional SND...

BACKGROUND: Transoral robotic surgery (TORS) for oropharyngeal squamous cell carcinoma (OPSCC) has been associated with improved long-term dysphagia symptomatology compared with chemoradiation. Dysphagia in the perioperative period has been inadequately characterized. The objective of this study was to characterize short-term swallowing outcomes after TORS for OPSCC. METHODS: Patients undergoing TORS for OPSCC were enrolled prospectively. The Eating Assessment Tool 10 (EAT-10) was used as a measure of swallowing dysfunction (score >2) and was administered on postoperative day (POD) 1, 7, and 30...

Endometriosis predominantly affects the pelvic reproductive organs but can also affect the urinary tract. A number of theories for the pathogenesis of endometriosis have been suggested, but the exact mechanisms remain elusive. Endometriotic lesions can be found on both the ureter and bladder, and the optimal therapeutic approach depends on the extent, depth, and location of these lesions. Medical approaches, including hormonal therapies such as GnRH agonists and oral contraceptives, tend to be a temporary measure, but can be useful in a preoperative setting or if the patient is unsuitable for surgery, and are also useful as a postoperative treatment...

Although anticoagulation remains the mainstay of therapy for patients with venous thromboembolism, guidelines recommend the use of inferior vena cava (IVC) filters in those who fail anticoagulation or have contraindications to its use. Short-term use of filters has proven effective in reducing the rate of pulmonary embolism. However, their extended use is associated with a variety of complications such as thrombosis, filter migration, or caval perforation, thus making a case for timely filter retrieval. This is the case of a 68-year-old female with a history of chronic oral anticoagulation use for multiple deep venous thrombi (DVT) and pulmonary emboli (PE) who required cervical and thoracic spinal intervention for spondylosis and foramina stenosis...

Robotic surgery has become the standard of care for many procedures outside of otolaryngology and now is gaining momentum within our specialty. The da Vinci (Intuitive Surgical, Sunnyvale, CA) robot has several advantages to human hands, including removal of tremor and better access to lesions because of increased degree of movement of the articulated instruments. The glottis has rarely been addressed using robotic surgery because access was previously thought to be difficult because of the limitations of currently used retractors, which include poor base of tongue and oral commissure retraction resulting in lack of exposure of the glottis in many patients and lack of space for the robotic instruments to occupy...

PURPOSE: Trans-oral robotic surgery (TORS) followed by adjuvant radiation therapy (RT) is becoming popular in treating node-positive tonsillar squamous cell carcinoma (SCC). One potential benefit is eliminating irradiation of the primary site when the tumor is widely resected, and targeting the neck only. This study assessed whether omitting the tumor bed provides any dosimetric or clinical advantage. METHODS AND MATERIALS: We identified 21 patients with primary tonsillar SCC that were treated with TORS followed by RT to the ipsilateral neck and primary (N+P) site...

OBJECTIVES: The diagnosis of cancer of unknown primary (CUP) in head and neck occurs when the treating clinicians have utilised all available diagnostic tests and failed to identify the origin of the disease. There is no agreed consensus on which diagnostic investigations to use, or the order in which to use them in, although broad recommendations exist. Small tumours arising in the tongue base can be below the limits of resolution of conventional diagnostic techniques. Given the difficulty in targeting the tongue base, current practice involves blind random biopsies, which leads to a variable detection rate...

Transoral thyroid surgery allows the surgeon to conceal incisions within the oral cavity without significantly increasing the amount of required dissection. TORT provides an ideal scarless, midline access to the thyroid gland and bilateral central neck compartments. This approach, however, presents multiple technical challenges. Herein, we present our experience using the latest generation robotic surgical system to accomplish transoral robotic thyroidectomy (TORT). In two human cadavers, the da Vinci Xi surgical system (Intuitive Surgical, Sunnyvale, CA, USA) was used to complete TORT...

BACKGROUND AND OBJECTIVES: Benign duodenal neoplasm is a rare occurrence. Minimally invasive tumor resection and anastomosis formation with an OrVil catheter is a novel approach to treating this disease. In this article, we present a new technique for duodenojejunal anastomosis. This technique was applied in 4 patients with benign distal duodenal tumors who were treated with minimally invasive surgery with robotic assistance. METHODS: In 4 patients, after the removal of distal duodenal masses with a robotic technique, an orifice in the duodenum was opened to allow for the passage of a guidewire...

Transoral robotic surgery (TORS) is a technique used to treat oral, throat, and skull base cancers using a minimally invasive robotic approach through the mouth and throat. The TORS procedure allows deeper access and dissection of suspicious lesions and neoplastic growths in the oral cavity and those that extend from the throat to the base of the skull. Robotic surgery allows the surgeon to operate in tight spaces without a large open incision. This article discusses symptoms and risk factors of oral, throat, and skull base cancers; types of procedures that can be performed using the TORS approach; specialized instrumentation; patient selection; surgical advantages and disadvantages; patient benefits; and the role of the surgical team in preparing to intraoperatively care for the TORS patient...

Trans Oral Robotic Surgery (TORS) is a prominent surgical approach for the resection of oropharyngeal tumors without division of the lip and mandible. Some defects following TORS are large and complex enough to benefit soft-tissue coverage. The pedicled temporalis muscle flap is a versatile and reliable flap and may be a valid option to reconstruct defects of the lateral pharyngeal wall and partial soft palate.

This case report describes the use of trans-oral robotic surgery (TORS) for the excision of a combined laryngocele. Mixed or combined laryngoceles extend from the supraglottic larynx through the thyrohyoid membrane into the neck. Surgical excision for these benign lesions often requires combined external (transcervical) and internal (transoral endoscopic) approaches which carry significant morbidity. We present the case of a 37-year-old male who was diagnosed with a large laryngopyocele and was subsequently managed with a transoral excision using the da Vinci Si surgical robot system...
