Summary

Endoscopic neck dissection (END) is feasible in cadavers, with most lymph nodes removed. This minimally invasive technique showed high efficacy and preserved major neck structures.

Area of Science:

  • Surgical Innovation
  • Anatomical Studies
  • Minimally Invasive Procedures

Background:

  • Traditional open neck dissection carries risks of morbidity.
  • Endoscopic techniques offer potential for reduced invasiveness in head and neck surgery.

Purpose of the Study:

  • To assess the feasibility and efficacy of endoscopic neck dissection (END) in a human cadaver model.
  • To evaluate the safety of END concerning major neck structures.

Main Methods:

  • Experimental study involving endoscopic neck dissection on five human cadavers.
  • Comparison of endoscopic versus open neck dissection specimen retrieval.
  • Pathological assessment of retrieved specimens for lymph node yield and structural integrity.

Main Results:

  • Endoscopic neck dissection was successfully performed on ten sides in five cadavers.
  • High efficacy (92%) in lymph node retrieval, with minimal additional yield from completion open dissection.
  • Minor injuries to the internal jugular vein and phrenic nerve occurred, but major structures were generally preserved.

Conclusions:

  • Endoscopic neck dissection is a feasible procedure in human cadavers.
  • The technique allows for the removal of the majority of neck lymph nodes with preservation of critical anatomical structures.
