Summary

Autopsy dissections revealed a previously undescribed nerve branch connecting the recurrent laryngeal nerves in 10 of 12 subjects. This finding offers new insights into laryngeal nerve anatomy.

Area of Science:

  • Anatomy
  • Neuroscience

Context:

  • Study of the laryngeal nerve anatomy during autopsy.
  • Investigation conducted within the European Research Group on the Larynx (G.R.E.L.).

Purpose:

  • To investigate the anatomical variations and connections of the recurrent laryngeal nerves.
  • To identify and describe any previously undocumented nervous structures in the neck.

Summary:

  • Twelve autopsies on non-conserved human corpses were performed to study laryngeal nerve anatomy.
  • A connecting nerve branch between the recurrent laryngeal nerves (anastomotic ansa) was observed in 10 out of 12 subjects.
  • This newly identified branch, located between the trachea and esophagus, has not been previously described in existing literature.

Impact:

Related Experiment Videos

  • Highlights a potentially significant anatomical variation in recurrent laryngeal nerve pathways.
  • Suggests the need for further microscopic, ultrastructural, histomorphometric, and electrophysiological studies.
  • May have implications for understanding laryngeal nerve function and surgical procedures.
