The aim of the present workshop is to transfer to the participants the experience on endoscopic/microscopic resections of malignant head and neck cancers, by lectures, videos and round tables. The following topics will be discussed: TLM trans oral laser microsurgery, TORS trans oral robotic surgery, TOUSS trans oral ultrasonic surgery, and TRS trans oral radiofrequency surgery. All these surgical methods share a mini invasive approach compared to the classical open surgery. Mini invasive approaches should ensure a better quality of life with the same survival rates.
