Introduction: The measurements of PA can be an anatomical landmark used for ethnic differentiation in human identification and provide information for surgical procedures and nasal reconstruction in otolaryngology. There are many variations in nasal bone shape among the different population e.g. The nose is much broader with thickened upper nasal region in East Asians. It is longer and more prominent in Middle Eastern and Southern European populations. Most Egyptian skulls are typically North African Caucasians.
