Aims: The objectives of this study are the assessment of the following facial anthropometric parameters of adult Saudi population: IntercanthalDistance (ICD), Inter-alar Width (IAW), Inter-commissural Width (ICW) and Maxillary Inter-canine Distance (MIC). And to compare these parameters (ICD, IAW, ICW, and MIC) between Saudi males and females and to determine the correlation between investigated facial parameters. Materials & Methods: The study was conducted at King Khalid University, two hundreds and ten subjects both males and females ranging in age from 17 to 35 years were included in this prospective cross-sectional analytical study. Simple random selection of all students, interns and patients who had fulfilled the criteria of selection and accept to participate in the study by signing consent form. Electronic Digital Caliper with resolution of 0.01 mm was used for all measurements. Results & Discussion: Data were collected and analyzed using SPSS version 13.0. Mean, Standard Deviation (SD), minimum, maximum and Standard Error of Mean (SEM) were calculated. Unpaired t-test was used to determine the difference in means between males and females. Pearson’s linear correlation coefficient was used to measure the degree of linear relationships between the three facial measurements for each subject. Conclusion: The present study establishes a preliminary baseline value for intercanthal distance, inter-alar width; inter-commissural width and maxillary inter-canine distance in adult Saudis.
