Preserving the spinal accessory nerve (SAN) during neck dissection (ND) improves shoulder function. Adjuvant radiotherapy (ART) after ND does not negatively impact shoulder function or SAN integrity.

Area of Science:

  • Oncology
  • Neurosurgery
  • Rehabilitation Medicine

Background:

  • Neck dissection (ND) for head and neck cancer can impact shoulder function.
  • The spinal accessory nerve (SAN) is crucial for shoulder movement.
  • Understanding the effects of ND techniques and adjuvant radiotherapy (ART) on shoulder function is vital for patient outcomes.

Purpose of the Study:

  • To evaluate the impact of preserving the spinal accessory nerve (SAN) during neck dissection (ND) on shoulder function.
  • To assess the influence of adjuvant radiotherapy (ART) following ND on shoulder function and SAN integrity.

Main Methods:

  • Prospective study of 57 head and neck cancer patients undergoing ND.
  • Evaluation of shoulder range of motion (goniometry) and muscle strength (manual testing).

  • Electromyography (EMG) used to assess SAN function (denervation, neurogenic involvement) and grouped by ND type (RND vs. MRND/SND) and ART (yes/no).

    • Main Results:

    • Modified radical ND (MRND)/selective ND (SND) resulted in significantly better shoulder range of motion and muscle strength compared to radical ND (RND).
    • All ND types led to statistically significant impairments in shoulder function and higher SAN denervation/neurogenic involvement compared to controls.
    • Adjuvant radiotherapy (ART) did not demonstrate a negative effect on shoulder function or SAN integrity across all ND groups.

    Conclusions:

    • Adjuvant radiotherapy (ART) does not adversely affect shoulder function post-neck dissection (ND).
    • Spinal accessory nerve (SAN) function is consistently impaired even with macroscopic preservation during ND.
    • Choosing less invasive ND techniques like MRND/SND is associated with better shoulder function outcomes.
