MIDDLE CERVICAL GANGLION AND VERTEBRAL GANGLION- CONTROVERSIES UNVEILED
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 38
Abstract
BACKGROUND Great divergences are there regarding the occurrence and nomenclature of Middle Cervical Ganglion (MCG) and Vertebral Ganglion (VG) in human cervical sympathetic chain. The lack of a detailed knowledge of its branching pattern and vascular relations will lead to iatrogenic injury complicating many surgical procedures in the neck. MATERIALS AND METHODS The study was done on 50 cervical sympathetic chains by bilateral neck dissection of 25 adult cadavers in the Department of Anatomy, Medical College, Thiruvananthapuram. The vascular relations, branches and dimensions of Superior Cervical Ganglion (SCG), Inferior Cervical Ganglion (ICG), Stellate Ganglion and other intermediate ganglia were carefully dissected out and studied. RESULTS SCG was seen in 100% cases, Inferior Cervical Ganglion (ICG) in 72% cases and stellate ganglion in 28% chains. Out of the two intermediate ganglia between SCG and ICG, one seen in close relation to Inferior Thyroid Artery (ITA) was concluded as MCG (44%) and another ganglion which was always over vertebral artery was concluded to be VG (72%). The branches arising from the ganglia were Gray Rami Communicantes (GRC), vascular branches and medial visceral branches. Vertebral nerve from VG was present in 5.6% cases. CONCLUSION The VG is more frequently present than MCG. Also, comparative studies between the dimensions of MCG and VG when seen alone or together show no significant relation suggesting that both are independent ganglia and one is not a detached part of another.
