Selective neck dissection, particularly involving sublevel IIB, can lead to significant spinal accessory nerve impairment and reduced shoulder function. Superselective dissection may offer better functional outcomes for patients with laryngeal carcinoma.

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Oncologic Surgery

Background:

  • Neck dissection is a critical surgical procedure for laryngeal carcinoma.
  • Assessing functional outcomes, especially spinal accessory nerve (SAN) and trapezius muscle function, is crucial post-surgery.
  • Different neck dissection techniques may impact nerve integrity and shoulder function differently.

Purpose of the Study:

  • To evaluate the clinical and functional outcomes of selective versus superselective neck dissections.
  • To specifically assess the impact on spinal accessory nerve conduction, trapezius muscle activity, and shoulder function.
  • To compare outcomes between patients undergoing selective neck dissection (SND) and superselective neck dissection (SSND).

Main Methods:

  • Retrospective analysis of 17 patients with clinically staged N0 laryngeal carcinoma undergoing neck dissection (Feb 2008-Jul 2010).

Modified Radical Neck Dissection for Cervical Metastasis

Published on: February 20, 2026

  • Group A: 11 patients underwent SND (levels IIA-IIB, III-IV). Group B: 6 patients underwent SSND.
  • Functional evaluation included clinical examination, electromyography (EMG), electroneurography (motor action potential - MAP), arm abduction test, and quality of life questionnaire at pre-surgery (T0), 8 days post-surgery (T1), and 21 days post-surgery (T2).

    • Main Results:

    • SND (Group A) showed significantly reduced MAP values at T1 (1.35) and T2 (1.03) compared to SSND (Group B) (T1: 6.15, T2: 6.43).
    • EMG revealed more denervation signs and absent voluntary activity in Group A (10/11 patients) than in Group B (3/6 patients) at T2.
    • Arm abduction was poorer in Group A (2.5) than Group B (4.0), with similar quality of life scores.

    Conclusions:

    • Surgical manipulation of the spinal accessory nerve, especially in sublevel IIB during selective neck dissection, is associated with severe nerve conduction impairment.
    • Superselective neck dissection appears to preserve spinal accessory nerve function and shoulder mobility more effectively.
    • These findings suggest SSND may be a preferable approach for maintaining functional outcomes in select laryngeal cancer patients.
