Submental Approach Robotic-Assisted Neck Dissection (SARAND) enables bilateral dissections through a single incision. This minimally invasive technique shows potential for reduced neck morbidity and combined tumor excision.

Area of Science:

  • Head and Neck Surgery
  • Robotic Surgery
  • Minimally Invasive Procedures

Background:

  • The robotic-assisted extended "Sistrunk" approach (RESA) showed promise for hypopharyngeal and laryngeal tumors.
  • Further development led to the Submental Approach Robotic-Assisted Neck Dissection (SARAND) for bilateral dissections.

Purpose of the Study:

  • To evaluate the feasibility of SARAND for bilateral neck dissections (levels I-IV).
  • To assess the utility of multiport and single-port robotic platforms for this approach.

Main Methods:

  • Bilateral neck dissections (levels I-IV) were performed on three cadavers.
  • Both multiport and single-port robotic platforms were utilized via a submental incision.

Main Results:

Identification and Protection of the Recurrent Laryngeal Nerve during Transoral Robotic Thyroidectomy

Published on: October 24, 2025

  • Feasibility of performing levels I-IV dissections through a single submental incision was demonstrated with both robotic platforms.
  • A central working space over the hyoid bone and boom rotation provided optimal access to all neck levels.

Conclusions:

  • SARAND is a promising minimally invasive technique for unilateral and bilateral neck dissection.
  • It may reduce neck morbidity compared to conventional methods.
  • SARAND potentially allows for simultaneous neck dissection and primary tumor excision via median pharyngotomy.
