A STUDY OF BRANCHING PATTERN OF EXTERNAL CAROTID ARTERY IN THE CAROTID TRIANGLE – A CADAVERIC STUDY

Abstract

Background Carotid triangle is an important neurovascular area located in the anterior cervical region of the neck. Variations in the external carotid artery in carotid triangle may complicate surgeries like radical neck dissection, aneurysm repair in the carotid triangle To study the branching pattern and variations of external c Aim and Objective arotid artery in carotid triangle This study includes 30 formalin xed cadavers from the Department of Ana Method tomy, Sri lakshmi Narayana institute of medical sciences Puducherry . This study includes all the cadavers during routine anatomical dissection by the students. In this present study Results both sides of the neck regions , a total of 60 sides were dissected. External carotid artery branches in the carotid triangle were traced. In the study period we found 3% of superior thyroid artery arising from common carotid artery and common unilateral linguofacial trunk in 6% of cadavers. Other branches of external carotid artery in the carotid triangle were traced. Ca Discussion And Conclusion rotid triangle is a vascular area contains common carotid artery and its terminal branches, important area for auscultation and palpation of vessels. With in the carotid triangle common carotid artery divides into internal and external carotid arteries at the level of upper border of thyroid cartilage. External carotid artery gives eight branches with in this ve branches arises from carotid triangle. The study of branches of external carotid artery in the carotid triangle was paramount important to avoid iatrogenic injury during neck dissection.
