Selective neck dissection resulted in less spinal accessory nerve damage and shoulder disability compared to radical procedures. Patients undergoing selective dissection recovered shoulder strength within six months post-operation.

Area of Science:

  • Oncology
  • Neurosurgery
  • Rehabilitation Medicine

Background:

  • Neck dissection is a surgical procedure for head and neck cancers.
  • Potential complications include shoulder pain and muscle weakness due to spinal accessory nerve damage.

Purpose of the Study:

  • To evaluate shoulder pain, muscle strength, and spinal accessory nerve function after different types of neck dissection.
  • To compare the functional outcomes based on the extent of neck dissection performed.

Main Methods:

  • Prospective study of 21 head and neck cancer patients.
  • Subjective shoulder pain assessment, objective isokinetic strength testing.
  • Electromyography and electroneurography of spinal accessory nerve function.

Main Results:

  • Radical neck dissection led to shoulder pain (100%) and shoulder droop (80%).
  • Selective neck dissection showed relatively normal spinal accessory nerve function.
  • Shoulder strength decreased at 1 month but returned to baseline by 6 months in selective dissection patients.

Conclusions:

  • Selective neck dissection causes minimal spinal accessory nerve impairment and shoulder disability.
  • Surgical technique influences functional outcomes and recovery after neck dissection.
