Abstract: Introduction: Facial symmetry refers to a complete match in size, location, shape and arrangement of each facial components. Asymmetry refers to the bilateral difference between such components. A perfect bilateral symmetry almost never exists in the human body so is facial symmetry. Aim and objective: Analysis and evaluation of facial asymmetry in different facial forms. Materials and Methods: Seventy-five Subjects within age group of fifteen to thirty -five years were selected among the patients visited to the department of orthodontics and dentofacial orthopaedics at Mithila minority dental college and hospital, Darbhanga, Bihar. Informed consent was taken from the patients. Digital photographs were selected and equally divided in each facial forms. The photographs were cropped by using Adobe photoshop and analysis was done by Digimizer software. The photographs were analyzed for 5 horizontal and 3 midline parameters. ANOVA test was performed to analyze the significant difference (at P ≤ 0.05)Results: The study compared vertical and horizontal facial parameters across Euryprosopic, Mesoprosopic, and Leptoprosopic facial types using One-Way ANOVA and t-tests. Results showed significant differences in vertical measurements, with Leptoprosopic individuals exhibiting the highest values across all parameters, followed by Euryprosopic, while Mesoprosopic had the lowest. Horizontal parameters also varied significantly, with Leptoprosopic individuals consistently having the highest values. However, comparisons between the right and left sides for both vertical and horizontal measurements showed no significant differences, indicating facial symmetry across all types. The study utilized SPSS 23.0 for statistical analysis, with a significance level set The study revealed significant differences in vertical and horizontal facial parameters among Euryprosopic, Mesoprosopic, and Leptoprosopic facial types, with Leptoprosopic individuals exhibiting the highest values across all measurements. These variations highlight distinct morphological characteristics associated with each facial type.
