Simple Summary Transoral resection of head and neck cancer represents one of the main approaches in the treatment of head and neck tumours. However, it can be challenging due to the difficult anatomy and complex functions of the pharynx and larynx. Moreover, organ preservation has become an important topic in head and neck surgery. Contemporary approaches aim to improve quality of life and cosmetic results, and to reduce treatment-related morbidity and mortality. The Flex Robotic System is a device intended for robot-assisted visualization and surgical site access to the head and neck. It is a hybrid technology that combines the flexibility of an endoscope to access the surgical site, and the ability to stiffen to perform the procedure. Abstract The Flex Robotic System is a device intended for robot-assisted visualization and surgical site access to the head and neck. The aim of this review is to summarize the current knowledge about the Flex Robotic System in head and neck transoral robotic surgery (TORS). The primary search was performed using the term “Flex Robot” across several databases (PubMed, Embase, Cochrane, Scopus). Patients were treated for both benign and malignant diseases. The oropharynx was the most frequent site of disease, followed by the supraglottic larynx, hypopharynx, glottic larynx, oral cavity, and salivary glands. Most of the studies did not reveal major intra- or post-operative complications. Bleeding incidence was low (1.4–15.7%). Visualization of the lesion was 95–100%, while surgical success was 91–100%. In conclusion, lesions of the oropharynx, hypopharynx, or larynx can be successfully resected, thus making the Flex Robotic System a safe and effective tool, reducing the morbidity associated with traditional open surgery.
