Surgical and oncological outcomes of transoral robotic total laryngectomy: A case series.

Abstract Objective To evaluate the oncological, functional and voice rehabilitation outcomes of transoral robotic surgery for total laryngectomy (TORS-TL). Methods A retrospective chart review of patients treated by TORS-TL was conducted at a single academic medical center. The following outcomes were studied: indication; average robotic set-up and operative times; mean estimated blood loss; postoperative complications; re-feeding features; mean hospital stay; need of adjuvant therapy and voice rehabilitation type. Results TORS-TL was performed in 10 patients for the following indications: nonfunctional larynx (N = 2); low-grade cricoid chondrosarcoma (N = 3) and recurrent laryngeal cancer after (chemo) radiation (N = 5). Two patients were excluded because the larynx was not exposable. Average robotic set-up and operative times were 20 and 278 min, respectively. The mean estimated blood loss was 50 mL. The mean hospital stay was 13.9 days (8–28 days). There was no local recurrence in patients operated for cancer recurrence (N = 5) 5 years after the surgery. Distant metastases occurred in one patient. A patient with laryngeal chondrosarcoma experienced local failure 3 years after TORS-TL. The voice rehabilitation consisted of esophageal voice (N = 2) and tracheoesophageal prosthesis (Provox®, N = 8). The main reasons for prosthesis replacement were transprosthetic (79%) and periprosthetic leaks (21%). The median lifespan of prostheses was 81 days. Conclusion TORS-TL may be a safe and effective surgical approach for selected surgical indications. Future controlled studies are needed to determine additional indications and limitations of this procedure.
