The thin ALT perforator flap for oropharyngeal robotic-assisted reconstruction

Since a few years, the transoral robotic surgery reduced the morbidity of oropharyngeal tumors excision. Large posterior tumors can now be removed without any scar visible on the face. In this context and to respect the thinness required for reconstructions at the junction of the upper aerodigestive tract, the free radial forearm flap still remains the solution of choice. However, if the transoral robotic surgery respects the anatomy and the aesthetics of patients at the visible and social area that represents the face, the forearm flap provides visible scars on the other region of social interaction that represents the upper limb. The aim of our work was to prove the feasibility and the benefits in terms of reducing sequelae when using a thin anterolateral perforator flap harvested above the plane of the superficial fascia. We present this new original method in detail and the advantages it offers to patients after surgery.
