INFERIOR CERVICAL GANGLION AND STELLATE GANGLION- CONCEPTS REVISITED
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 13
Abstract
BACKGROUND Awareness of the regional anatomy of the cervical sympathetic chain may help the surgeons in identifying and preserving this structure during related surgical procedures. Care must be taken by the spinal surgeon to protect the chain and its branches, while dissecting the longus colli muscle especially in the root of neck for anterior spinal surgeries. 1 The present study aims to define the lower two ganglia, i.e. inferior cervical ganglion and stellate ganglion by tracing their vascular relations, dimensions and branches. The frequency of occurrence of these ganglia, which is surgically significant is also studied. MATERIALS AND METHODS The study was descriptive, done in 50 cervical sympathetic chains by bilateral neck dissection of 25 adult cadavers in the Department of Anatomy, Medical College, Thiruvananthapuram. The superior cervical ganglion (SCG), inferior cervical ganglion (ICG), stellate ganglion (SG) and the intermediate ganglia were carefully dissected out and studied. RESULTS SCG was seen in 100% cases, middle inferior ganglion (MCG) in 44%, vertebral ganglion (VG) in 72%, ICG in 72% cases and stellate ganglion in 28% chains. The branches arising from the ganglia were Gray rami communicantes (GRC), vascular branches and medial visceral branches. Vertebral nerve from ICG was present in 4% cases and from stellate in 2% cases. CONCLUSION In the lower part of cervical sympathetic chain, ICG is more frequently present than SG.
