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.
