Area of Science:

  • Neurosurgery
  • Anatomy
  • Surgical Techniques

Background:

  • The spinal accessory nerve (SAN) is a significant risk during head and neck surgeries.
  • Damage to the SAN can lead to severe functional deficits.
  • Accurate nerve identification is crucial for preventing surgical complications.

Purpose of the Study:

  • To present a straightforward technique for identifying the spinal accessory nerve (nerve XI).
  • To enhance surgical safety in the lateral neck and shoulder region.
  • To reduce the risk of iatrogenic injury to the spinal accessory nerve.

Main Methods:

  • A simple method utilizing pinprick hyperesthesia was employed.
  • This technique allows for accurate intraoperative delineation of the spinal accessory nerve's course.
  • The method focuses on identifying sensory changes indicative of nerve proximity.

Main Results:

  • Pinprick hyperesthesia effectively identified the anatomical path of the spinal accessory nerve.
  • The technique provides a reliable means to map the nerve prior to surgical incision.
  • This method aids surgeons in avoiding inadvertent transection of the nerve.

Conclusions:

  • The pinprick hyperesthesia method is a valuable tool for spinal accessory nerve identification.
  • Implementing this technique can significantly decrease the risk of severing the nerve during surgery.
  • Accurate preoperative and intraoperative nerve mapping is essential for safe head and neck procedures.
