AI Summary & Key Takeaways
AI InsightThe average distancefrom the internal aspect of the center of the pterion to the opticcanal was 4.02±0.12 cm, to the sphenoid ridge was 0.97±0.09cm,to the stem of middle meningeal artery was 0.99±0.07cm and to itsnearest branches was 0.58±0.12 cm.Conclusion: These findings will be useful in relating theposition of the pterion to several important landmarks in varioussurgical approaches.

Abstract
Objectives: The pterional site is important as it lies in closeproximity to the middle meningeal artery and on the left side, toBroca’s motor speech area. This location is important in surgicalapproaches to the anterior and middle cranial fossae. This studywas conducted to determine the location and type of pterion in agroup of South Indian human skulls.Materials and Methods: The study was conducted on 50 dryadult skulls. The distance from pterion to various bony landmarkswere measured on both sides using a vernier caliper. In addition,the pterion was classified depending on bones involved in thearticulation, its symmetry and its position in the skull.Results: In the present study a sphenoparietal type of pterionwas the most common (78%). The average distance from thecenter of the pterion to the frontozygomatic suture was 3.97±0.10cm, to the zygomatic arch was 3.27±0.06 cm. The average distancefrom the internal aspect of the center of the pterion to the opticcanal was 4.02±0.12 cm, to the sphenoid ridge was 0.97±0.09cm,to the stem of middle meningeal artery was 0.99±0.07cm and to itsnearest branches was 0.58±0.12 cm.Conclusion: These findings will be useful in relating theposition of the pterion to several important landmarks in varioussurgical approaches.
