          Abstract

          Throughout the twenty-first century, robotic surgery has been used in multiple oral surgical procedures for the treatment of head and neck tumors and non-malignant diseases. With the assistance of robotic surgical systems, maxillofacial surgery is performed with less blood loss, fewer complications, shorter hospitalization and better cosmetic results than standard open surgery. However, the application of robotic surgery techniques to the treatment of head and neck diseases remains in an experimental stage, and the long-lasting effects on surgical morbidity, oncologic control and quality of life are yet to be established. More well-designed studies are needed before this approach can be recommended as a standard treatment paradigm. Nonetheless, robotic surgical systems will inevitably be extended to maxillofacial surgery. This article reviews the current clinical applications of robotic surgery in the head and neck region and highlights the benefits and limitations of current robotic surgical systems.

          The global incidence of lip, oral cavity, and pharyngeal cancers by subsite in 2012.

          By using data from the International Agency for Research on Cancer publication Cancer Incidence in 5 Continents and GLOBOCAN, this report provides the first consolidated global estimation of the subsite distribution of new cases of lip, oral cavity, and pharyngeal cancers by country, sex, and age for the year 2012. Major geographically based, sex-based, and age-based variations in the incidence of lip, oral cavity, and pharyngeal cancers by subsite were observed. Lip cancers were highly frequent in Australia (associated with solar radiation) and in central and eastern Europe (associated with tobacco smoking). Cancers of the oral cavity and hypopharynx were highly common in south-central Asia, especially in India (associated with smokeless tobacco, bidi, and betel-quid use). Rates of oropharyngeal cancers were elevated in northern America and Europe, notably in Hungary, Slovakia, Germany, and France and were associated with alcohol use, tobacco smoking, and human papillomavirus infection. Nasopharyngeal cancers were most common in northern Africa and eastern/southeast Asia, indicative of genetic susceptibility combined with Epstein-Barr virus infection and early life carcinogenic exposures (nitrosamines and salted foods). The global incidence of lip, oral cavity, and pharyngeal cancers of 529,500, corresponding to 3.8% of all cancer cases, is predicted to rise by 62% to 856,000 cases by 2035 because of changes in demographics. Given the rising incidence of lip, oral cavity, and pharyngeal cancers and the variations in incidence by subsites across world regions and countries, there is a need for local, tailored approaches to prevention, screening, and treatment interventions that will optimally reduce the lip, oral cavity, and pharyngeal cancer burden in future decades.

              Transoral robotic surgery (TORS) for base of tongue neoplasms.

              To develop a minimally invasive surgical technique for the treatment of base of tongue neoplasms using the optical and technical advantages of robotic surgical instrumentation. Ten experimental procedures including tongue base exposure and dissections were performed on three cadavers and two mongrel dogs. Transoral robotic surgery (TORS) was then performed on three human patients with tongue base cancers in a prospective human trial. Using the da Vinci Surgical Robot (Intuitive Surgical, Inc., Sunnyvale, CA), we performed a total of 10 base of tongue resections on edentulous and dentate cadavers as well as live mongrel dogs. In the cadaver models, exposure was evaluated using three different retractors, the Dingman, Crowe Davis, and FK retractors. The three human patients underwent TORS surgery of their tongue base cancers under an institutional review board approved prospective clinical trial. The ability to identify and preserve or resect key anatomic structures such as the glossopharyngeal, hypoglossal, and lingual nerves as well as techniques for identifying the lingual artery and achieving hemostasis were developed. The da Vinci Surgical Robot provided excellent visualization and enabled removal of the posterior one third to one half of the oral tongue in cadavers, dogs, and human patients. Among the three retractors evaluated, the FK retractor offered the greatest versatility and overall exposure for robotic instrument maneuverability. Complete resection to negative surgical margins with excellent hemostasis and no complications was achieved in the live patient surgeries. TORS provided excellent three-dimensional visualization and instrument access that allowed successful surgical resections from cadaver models to human patients. TORS is a novel and minimally invasive approach to tongue neoplasms that has significant advantages over classic open surgery or endoscopic transoral laser surgery.
