Abstract
Objective: To evaluate the variations of superficial part of cervical plexus and its branches in Thais.
Methods: We dissected bilaterally in 108 cervical plexuses in Thai cadavers. The anatomic variations of origins and its cutaneous branches of the superficial part of cervical plexus were identified and recorded.
Results: The superficial part of cervical plexus derived from the ventral rami of C2, C3, and C4. Its branches consisted of the lesser occipital, great auricular, transverse cervical and supraclavicular nerves. These cutaneous (or superficial) nerves mainly derived from ventral rami of C2-C3 except the supraclavicular nerve from C3-C4. They supplied the skin and superficial structures of the head, neck and shoulder. The anatomic variations of these nerves occurred in both sides. There was no statistical difference with regard to either gender or side.
Conclusions: The knowledge of the anatomic variations of cutaneous branches of the superficial cervical plexus from this study could be useful for clinicians in anesthesia blocks, surgical procedures, treatment of pain and abnormalities relating to these cervical nerves.
