Abstract
Objective: T o establish the cephalometric (Ceph.) norm by Ceph. for orthognathic surgery (COGS) analysis for Saudi population . Material and Methods: 500 adult Saudi samples (250 males and 250 females) with the age range of 18-30 years old were selected for this study. The selections of samples were based on a normal occlusal relationship, no history of facial trauma and no previous orthodontic treatment. Lateral Ceph. radiographs were tracing by CASSOS software and analyzed by SPSS software according to COGS analysis. Results: Signi fi cant differences were showed between the Saudi males and females on most of the Ceph. parameters. The Saudi males had a convex facial profile with chin prominent and more bimaxillary protrusion, upper and lower lip protrusion than the Saudi females . Conclusion: This study evaluated the craniofacial morphological difference between the male and the female population in Saudi Arabia by using COGS analysis. The finding of this study will help for better diagnosis of orthodontic and orthognathic surgical treatment planning and identify the morphological facial characteristics of Saudi patients.

Summary
Craniofacial morphometric assessment is one of the important parts of orthodontics for the researcher and clinician. People are more conscious about their facial aesthetic appearance due to increase social demand, global social media and improving socio-economic conditions. The standard value of most cephalometric studies must be depended on races, gender and age group of the same population [2]. Cephalometric (Ceph.) analysis should obtain from people of the same race, age and sex group [3,4,5]. Diverse and multi subraces peoples are present in the Arabic language speaking countries of Middle East [6,7]. Saudi Arabia is a country with multiregional sub ethnical groups in the Middle East region. By the influence of western global social media and movies, large numbers of Saudi Arabian peoples are looking for facial esthetic and orthodontic treatment from orthognathic surgeons and orthodontists
