Journal Title: Journal of Medical Science And clinical Research - Year 2017, Vol 5, Issue 4
Abstract
The posterior condylar foramen is largest of emmissory foraminas present in human skull. It is also called as condyloid canal.. Variations in posterior condylar canal may be asscuated with variations in posterior condylar vein which may be wrongly considered as pathological. So the study was done to assess prevalance, normal anatomic pattern and variations of `condylar canal. Study conducted to determine the variations in the occurrence of posterior condylar canal with patency and if patent whether Intrasinus or Retrosinus. 228 dry skulls of unkown sex and age studied from different medical colleges in Mumbai and Navi Mumbai. Skulls were examined by direct observation for bilateral and unilateral presence or absence of posterior condylar canal and also any other variations. By passing probe patency was checked to note whether canal is intrasinus or retrosinus. Study shown Posterior condylar canal was present in 83.33 % of skulls in which 48.68 % bilateral, 19.29 % Right Unilateral and 15.35 % Left Unilateral and 16.66% were bilateral absent . Study highlights the 80 % canals were Intrasinus and 20 % Retrosinus. Conclusion: Anatomical variations of post. condylar canal is important for radiologist, Neurosurgeons, ENT Surgeries thus study gives basic knowledge to surgeons before planning a surgery in occipital condylar regions.
