Abstract

Background: Transoral robotic surgery (TORS) is nowadays considered a valuable minimally invasive approach to treat oropharyngeal squamous cell carcinoma (OPSCC). The aim of this technique is to improve functional preservation and reduce morbidity with excellent oncologic outcomes compared to the traditional transoral approach and chemoradiotherapy (CRT). The purpose of this systematic review is to assess an exhaustive overview of functional outcomes of TORS for OPSCC by evaluating several parameters reported in the available literature, such as the prevalence and dependence of tracheotomy, feeding tubes (FTs) and percutaneous endoscopic gastrostomy (PEG), the length of hospitalization, swallowing scores, speech tests and quality of life (QoL) questionnaires. Methods: A systematic literature review has been performed following the PRISMA 2020 checklist statement. A computer-aided search was carried out using an extensive set of queries on the Embase/PubMed, Scopus and Web of Sciences databases relating to papers published from 2007 to 2024. Results: A total of 28 papers were systematically reviewed, reporting 1541 patients' data. The mean time of hospitalization was 6 days. A planned tracheotomy was performed in 8% of patients with a mean time of removal of 8 days. The prevalence and dependence of FT was 60% and 10%, respectively. Moreover, the presence of a high-stage T tumor with the contextual requirement of adjuvant therapies, the involvement of base tongues and the patient's age being >55 years increased the risk of requiring an FT and PEG. Swallowing and long-term QoL outcomes highlight the superiority of the TORS approach alone compared to TORS with adjuvant therapies. Conclusions: TORS presented various favorable functional outcomes compared to other surgical approaches and primary CRT. However, adjuvant therapies after TORS strongly reduced the advantage of the robotic procedure, thus suggesting that T1 and T2 tumors may benefit mainly from TORS alone.
