Oropharyngeal reconstruction after transoral robotic surgery

Transoral robotic surgery (TORS) has experienced an evolution in recent years. This technique has proved to be a safe and effective method for extirpation of select oropharyngeal tumors. Advances in technology as well as improved surgeon experience allow for the resection of larger, more complex cancers. Although healing by secondary intention remains the current standard for limited oropharyngeal defects, larger resections demand reconstruction with vascularized tissue to minimize morbidity and optimize functional outcomes. The objective of this review is to evaluate recent literature regarding oropharyngeal reconstruction after TORS.

A variety of reconstructive options to manage oropharyngeal defects exist. Several reconstructive algorithms have been suggested; however, careful consideration must be used to select the most ideal flap type. Locoregional flaps have shown excellent functional outcomes with limited morbidity. An increase in free flap reconstruction has been demonstrated, particularly among patients with larger TORS defects and following chemoradiation therapy. Despite limited data, robotic-assisted flap inset and microvascular anastomosis has recently shown promise.

Reconstruction and flap selection following TORS should be tailored to the patient and unique oropharyngeal defect. Functional outcomes are promising with low complication rates among these patients.
