Asymmetry of body parts can be observed both in normal and pathological conditions. A small congenital or acquired disproportion that does not cause functional and aesthetic disorders is considered acceptable. At the same time, the sudden asymmetry of the face, limbs and body parts often indicates the development of serious diseases. Diagnosis is carried out using physical techniques, instrumental visualization methods (X-ray, CT, ultrasound). Serious signs requiring urgent medical attention are facial asymmetry in stroke, joints in injuries, limbs in lymphedema, shoulders and shoulder blades in scoliosis, etc.
