Transoral robotic surgery for supraglottic cancer. A review of oncological and functional outcomes compared to open surgery.

Abstract

Supraglottic squamous cell carcinoma (SCC) represents a major surgical challenge in organ-preserving treatment. Type I open partial horizontal laryngectomy (OPHL I) is considered the most popular. To date, minimally-invasive approaches such as laser microsurgery and transoral robotic surgery (TORS) have gained increasing relevance. The aim of this narrative review is to obtain a descriptive comparison of functional and oncological outcomes from studies on patients with supraglottic SCC treated with OPHL I and TORS, respectively. A computerised search was performed using the Pubmed database for articles published from 2000 to 2023. A comparative analysis on functional and oncological outcomes of patients treated by TORS and OPHL I was performed. The present narrative review shows a superiority of TORS compared to open surgery for supraglottic SCC in terms of functional outcomes, while maintaining comparable oncological outcomes. Although recently introduced in the treatment of laryngeal pathology, TORS has been shown to be a reliable technique not only for functional but also for oncological outcomes, ensuring good overall survival, disease-free survival, and disease control rates comparable to OPHL I.
