Preserving the external jugular vein and cervical plexus during neck dissection reduces intracranial pressure and facial swelling. This technique also effectively prevents shoulder arm syndrome in oral cancer patients.

Area of Science:

  • Surgical Oncology
  • Head and Neck Surgery
  • Anatomy

Background:

  • Neck dissection is a critical procedure for oral cancer treatment.
  • Potential complications include increased intracranial pressure, facial swelling, and shoulder arm syndrome.

Purpose of the Study:

  • To evaluate the impact of preserving the external jugular vein and cervical plexus during neck dissection.
  • To assess the efficacy in reducing intracranial pressure, facial swelling, and preventing shoulder arm syndrome.

Main Methods:

  • A comparative study involving 20 oral cancer patients divided into two groups.
  • Facial interstitial pressure measurements before and after surgery.
  • Immunochemical staining to analyze lymphatic tube density.

Main Results:

  • Patients with preserved external jugular vein and cervical plexus showed lower and shorter-lasting increases in facial interstitial pressure.
  • Higher density of lymphatic tubes was observed around the internal jugular vein, accessory nerve, and sternocleidomastoid muscles compared to the preserved structures.

Conclusions:

  • Preserving the external jugular vein and cervical plexus is effective in mitigating post-operative intracranial pressure and facial edema.
  • This surgical approach successfully prevents the development of shoulder arm syndrome.
