Advances in anatomical visualization on the head and neck through robotic surgery: A Brazilian perspective
2021
Trans Oral Robotic Surgery (TORS) is an emerging technique that provides several benefits over existing treatment regimens for head and neck cancer, including smaller incisions, less bleeding, shorter term inpatient hospitalization, and reduced intensive care unit (ICU) length of stay. TORS allows a high resolution, magnified, three-dimensional wide view of the surgical field through an endoscope, avoiding large external cervical incisions and split-lip mandibulotomy, usually required in cancer surgeries of the oropharynx. The anatomy of the Oropharynx viewed from the perspective of the robotic surgeon is different from the anatomy taught in medical schools and residence/fellowship programs, which is more directly related to emergency procedures, open field surgery, and imaging exams. Developing an understanding of the anatomic relationships and landmarks from the "inside out" perspective is critical for any surgeon willing to perform surgical procedures through a transoral robotic approach. Here we address the major anatomic landmarks and structures in head and neck robotic surgeries and advantages and disadvantages of this approach. We emphasize the importance of imaging for successful outcomes, pointing out important anatomic landmarks considered as blind spots for surgeons in clinical and endoscopic evaluations. We also describe the Brazilian current scenario and future perspectives of Robotic Surgery in terms of training and access to this technique, including institutions that currently offer this service in the different regions of Brazil.
