Objective:
To assess the feasibility of the submental approach robotic-assisted neck dissection (SARAND) for minimally invasive bilateral procedures.
Approach:
- Study Design: Three fresh-frozen human cadavers were used to develop and evaluate the SARAND technique in a series of cadaveric resections.
- Surgical Techniques: Both multiport and single-port approaches were performed using the da Vinci Xi and da Vinci SP surgical systems, respectively.
Key Findings:
- SARAND allows for bilateral neck dissection through a single submental incision, minimizing tissue trauma.
- The technique provides adequate exposure and access to both primary tumors and neck lymphatics.
- Insufflation during the single-port approach improved visualization and reduced soft tissue collapse.
Interpretation:
Limitations:
- The study was conducted on cadavers, which may not fully replicate live surgical conditions.
- The da Vinci SP system's intended use is currently limited to transoral procedures in the EU.
Conclusion:
