Abstract

Introduction: Posterior Condylar foramina present just behind the occipital condyles, which transmits emissary vein connecting sub occipital venous plexus with intracranial sinuses. Materials and Methods: Study conducted on 60 dry human skulls. Each skull is observed for incidence, laterality and patency of posterior condylar foramina. Here patency of foramina is observed by probe. Result: We observed that 77% skulls have presence of condylar foramina and 23% have absence of foramina.50% skulls have bilateral foramina,20% skulls have left sided and 7% have right sided foramina.70% skulls have patent foramina and 30% skulls have absent patency. Conclusion: There is variation in incidence, laterality and patency of condylar foramina so knowledge of variation in condylar foramina is important for neurosurgeon and ENT surgeon in skull base surgery and also for radiologist.
