Body Asymmetries: Incidence, Etiology and Clinical Implications

Symmetry is defined as correspondence in size, shape and relative position of parts on opposite sides of a dividing line or median plane. Although the human body has a symmetrical appearance when viewed externally, most internal organs are asymmetrical with respect to the left and right sides. Human body shows anatomical as well as functional asymmetries: some of these are of great clinical significance. This paper aims to integrate the general knowledge of incidence, etiologic factors, and clinical implications of body asymmetries. Knowledge and understanding of these asymmetries is important to achieve a good diagnosis and focus on an appropriate treatment and management plan.
