Introduction: The anthropometric Auricular measurements play a crucial role for reconstruction of absent, congenitally deformed or lost ears in cases of burns and accidents. Even essential for the effective designing of hearing aids ensuring their fit and function optimally.The present study aim is to determine the lengths and widths of auricle, lobule, concha,base of the ear and auricular, lobular and conceal indices.The objective of the study is to derive linear regression equations to estimate ear dimensions from side and gender. Methods: The present study was conducted on 240(120 male and 120 female) medical students with 18 to 25 years of age, Department of Anatomy, Gautam Buddha Chikitsa Mahavidyalaya, affiliated to Ras Bihari Bose Subharti university,Dehradun,India. Results: The findings of the present study confirmed prominent Sexual dimorphism in Auricular parameters along with bilateral symmetry in medical students of Dehradun. Conclusion: This study's uniqueness lies in its focus on deriving linear regression equations from side and gender, which is a departure from traditional studies that have relied on stature, age, and other anthropometric models.
