TOUSS or TransOral Ultrasonic Surgery is a procedure designed for a minimally invasive approach to upper aerodigestive lesion treatment.

Based on the laparoscopic method and the philosophy of tackling the pathology from the least invasive way of access for the patient, TOUSS allows the treatment of pharynx and larynx cancer, along with other benign lesions of the head and neck through the mouth and avoiding external access.

The high-quality image of the endoscope allows for a neat and precise vision of the field. This, combined with the technology of cut and coagulation of the Thunderbeat, results in a safe, almost bloodless resection of the tumour.


TOUSS was designed in order to offer a minimally invasive surgery approach from the very beginning. It is based in the use of the endoscopic tool in a transoral fashion (that is, through the mouth) targeted to the head and neck pathology, both malign and benign. This way the patient will avoid the big physical consequences that are the usual aftermath of a classic open surgery. Up until the appearance of this technique, a transoral endoscopic surgery was only possible to do with a robotic platform, inaccessible to the vast majority of medical institutions worldwide.

TOUSS has become a surgical alternative to the robotic surgery, in the same cases the latter is applied. This is done with materials and technology accessible to most hospitals. The TOUSS philosophy consists on placing a bet in the development of minimally invasive surgery without the costs of a robot. This way this procedure is universalized for patients from different income backgrounds, making it more egalitarian.

The two key words that describe this project are: minimally invasive surgery and accessibility. Those are the concepts we like to promote: making it as universal as possible due to accessibility and offering a modern, high-quality, minimally invasive surgery.


A less invasive and detrimental surgery

TOUSS sets a main difference against traditional surgery in that it is a minimally invasive procedure, designed to inflict the least amount of damage possible to healthy tissue. Inspired by the concept brought by the laparoscopy of single access, TOUSS uses the mouth as a natural entryway to structures like the pharynx and larynx. Aided with the image accuracy of the videoendoscopes and ultrasonic technology, it will be possible to reach, correctly visualize and operate on anatomical regions available only under the reach of open jaw surgery before.

A fast and safe procedure

As the mouth is the natural access used in this technique, it is a shorter surgical procedure, for the extensive clinical approach to the area is no longer needed. Once reached the anatomical region, the resection is quick and bloodless thanks to the ultrasound asset. With its cut and coagulation function, its efficacy isn’t comparable to the laser technique. This gains importance when the lesion is found at the base of the tongue, a highly vascularized area where bleeding happens quite easily and frequently. Moreover, the videoendoscopic technology of the EndoEYE, providing an articulated tip with a reach of 100º, will allow a direct, high-quality visualization of the region. This is crucial to gain control over the vessels and tumour edges.

A reduction of bleeding

TOUSS allows for an almost bloodless surgery thanks to the Thunderbeat, an ultrasound forceps that safely coagulates blood vessels up to 7mm wide.

An intuitive and easily acquired technique

Professionals learning the TOUSS technique show early and fast improvement. The training in endoscopic surgery through the years makes it a manageable and intuitive technique.

A limitless and expandable idea

TOUSS offers the possibility of expansion inside the minimally invasive surgery of pharynx and larynx, which was tied to the robotic method up until recently. It allows the surgeon to reach anatomical regions only available by open surgery before, which conforms a great capital to exploit. The possibilities are vast: from its initial purpose of lesion removal, to the total laryngectomy, or its successful base of the tongue resection and reduction in sleep apnea (condition suffered by millions of people), this technique is versatile and can be easily reinvented. It opens up a very promising path of surgical investigation.

Economically more accessible equipment

One of the biggest advantages this new technique has to offer is the economic accessibility of the equipment used. The surgical robot, not only is very expensive to procure, but also needs thousands invested in its maintenance. This makes it non-accessible for many institutions. TOUSS is a simplified strategy based on a counter-current philosophy by using the endoscope in the head and neck surgery. It is accessible to any patient and medical institution. Not only does it mimic the results of robotic surgery, but also improves it in terms of mobility and aesthetic after the recovery.

A faster recovery

Experiencing a disease and surgical procedure can be difficult and distressing on the patient, especially if it is cancer. TOUSS provides to those in need of surgery to tackle disease, a solution that is far quicker and less traumatic than the classic procedures.

Reduced hospital stays

Because the surgery is minimally invasive, the patient won’t have to heal from major incisions, thus allowing a faster, less painful recovery. This will all mean shorter post-operational stays in the hospital.

Less post-operational issues

The issues that can come up when healthy tissue is damaged in order to access to certain anatomical regions is significantly reduced with a TOUSS approach. When a tracheotomy is needed, this is even more important, which can be discarded in many occasions, or even with the swallowing. Patients intervened with TOUSS have a less extensive cicatrization area, which enables the patient to preserve more nervous sensitivity and motor skills, the patient will start eating normally faster. These advantages are extremely important for patients that have gone through radiotherapy and quimotherapy treatments.


TOUSS was originally designed towards the treatment of patients in the field of oncology. A majority of pharynx and larynx lesion will easily be candidates for a transoral resection through a TOUSS approach. Nevertheless, it will be the patients suffering from malign pathology, and especially when the resection is on the bigger side, the ones that will benefit the most from this technique.

TOUSS can also be considered an alternative to the snoring surgery or the reduction of some benign lesions, because it is a quick, safe and minimally invasive option.

Yearly, several TOUSS courses are taught in different levels of expertise. Courses going from the profound knowledge of the anatomical area from a transoral and endoscopic access, to the mastering of the skills that keep being incorporated to an ever-evolving technique. These courses are a means to share ideas, discussing different concepts and create transcending working bonds.
