ANATOMICAL STUDY OF POSTERIOR CONDYLAR CANAL IN ADULT DRY HUMAN SKULL AND ITS CLINICAL IMPORTANCE

Dr. Nidhi Agrawal

Abstract :

Background: The posterior condylar canal is a skull base canal seen during the study of Norma basalis externa. It is located within the condylar fossa posterior to the occipital condyles. The canal transmits an emissary vein connecting sigmoid sinus with the sub occipital venous plexus. Objectives: The aim of our study is to determine the incidence, side predominance, patency and other anatomical variation of posterior condylar canal. Materials and Methods: The present study was conducted in 205 dry human skull obtained from department of Anatomy, N.S.C.B. Medical college Jabalpur (M.P.). Each skull was examined for the presence or absence of the canal, Patency of canal, and any other variations according to standard method. Result: In our study we found that 89% skull posses posterior condylar canal. The incidence of bilateral presence of canal is more (68%) than unilateral (22%). Intrasinus form of posterior condylar canal was 68% and retrosinus form was 26% of total skulls. Conclusion: To conclude that our study provides detailed data about the incidence, side predominance & patency about posterior condylar canal in Mahakoshal Region of central India. Our study gives basic knowledge to the clinicians and surgeons before planning a surgery in the occipital condylar regions.
