Preserving cervical root branches during selective neck dissection limits permanent anesthesia to a small neck area. Sacrificing these nerves results in widespread neck anesthesia, impacting sensory function.

Area of Science:

  • Head and Neck Surgery
  • Neurosurgery
  • Oncology

Background:

  • Selective neck dissection is a common procedure for head and neck cancers.
  • Sensory nerve preservation is a key consideration to minimize post-operative morbidity.
  • Understanding the impact of nerve preservation on sensory outcomes is crucial for surgical decision-making.

Purpose of the Study:

  • To evaluate sensory changes in the head and neck after selective neck dissection.
  • To compare sensory outcomes between procedures with and without preservation of cervical root branches.

Main Methods:

  • Retrospective cohort study involving 57 patients undergoing 84 neck dissections.
  • Utilized questionnaires and head and neck sensory examinations.
  • Assessed neck and facial sensory function at least 3 months post-surgery.

Main Results:

  • Preserving cervical root branches was associated with a small, localized area of anesthesia below the mandible (P=.03).
  • Neck dissections without nerve preservation led to anesthesia in all other neck areas (P=.02).

Conclusions:

  • Preservation of cervical root branches results in a limited, predictable area of permanent neck anesthesia.
  • Sacrifice of these nerve branches causes extensive anesthesia affecting the entire neck.
  • Nerve preservation techniques significantly mitigate sensory deficits after selective neck dissection.
