Oropharyngeal free flap reconstruction: Transoral robotic surgery versus open approach

Abstract

Objective: Transoral robotic surgery (TORS) has evolved since its 2009 US Food and Drug Administration approval for use in local stage T1–T2 oropharyngeal carcinoma. The ability to resect increasingly larger and more complex lesions has led to the need to introduce reconstructive techniques through this route, avoiding the classic transmandibular or pull-through approach. Few studies have compared the safety, efficacy, and advantages of TORS versus classic open approaches in oropharyngeal salvage surgery with reconstruction using microanastomosed flaps. Here we retrospectively compare our center's experience with the open approach and TORS and describe the technical variations used. Methods: Between 2013 and 2021, 30 stage III–IV oropharyngeal cancer patients underwent salvage surgery with reconstruction in our center. From 2013 to 2017, 15 patients underwent surgery with the classic open approach, and from 2018 to 2021, an additional 15 patients underwent TORS. We have compared surgical outcomes, post-surgical results, and survival in the two groups. Results: Patient characteristics were similar in the two groups. TORS was associated with shorter surgical time (p
