A prospective anatomic study of epipteric bones in dry human skulls of Karnataka

Abstract

Aim: To study the incidence of epipteric bones in the region of pterion in human skulls. Materials and Methods: The study was done for a period of two years in the department of Anatomy at Kempegowda Institute of Medical Sciences and Research center, Bengaluru. A total of 100 dry unknown skulls from bone sets possessed by first year students of Kempegowda Institute of Medical Sciences and Research center, Bengaluru of 2009 2011 batch were evaluated for the presence of epipteric bones. Results: Out of 100 skulls, epipteric bones were seen in the region of pterion in 24 skulls. Bilateral occurrence was noted in 8 skulls and unilateral occurrence was seen in the remaining 16 skulls. Among the unilateral occurrence, 6 were seen on the right side and 10 were seen on the left side. Conclusion: In conclusion, identification of the occurrence of epipteric bones at the site of pterion is important as they may be confused for fractures. Also, presence of epipteric bones may lead to complications in making burr holes at the pterion.
