Asymmetry Assessment for Saudi Adult Male Population: Grummons Analysis

Objectives: The prime aim of the following study is to measure the facial parameters of the horizontal plane, mandibular morphology and linear asymmetries using Grummons analysis (GA). Materials and methods: Standard posterior–anterior cephalogram (PAC) of 100 esthetically pleasing faces without any orthodontic treatment and craniofacial deformity were taken from the radiology archive. All radiographs are digitally analyzed for the GA. Various linear and angular variables were measured for horizontal plane, mandibular morphology, and linear asymmetries. Results: Descriptive analysis has been done using SPSS software. Mean disparities has been calculated to check the difference between different parameters with other ethnics. GA of PAC of Saudi adult male showed variable degrees of facial asymmetry. The lower third of the face showed greater asymmetries. Mandibular deviation, maxillary midline deviations, and mandibular midline deviation are 3.51 mm, 2.52 mm and 2.86 mm, respectively. Conclusion: This study has measured PAC; horizontal plane, mandibular morphology and linear asymmetries for the Saudi adult male using GA. Facial asymmetries are found to have a common finding in Saudi adult male subjects who have normal facial harmony.
