Cervical atlantoaxial asymmetry is usually abnormal and may be related to congenital deformity, trauma, etc. If accompanied by obvious discomfort symptoms, prompt treatment is needed. Atlantoaxial asymmetry is clinically serious and is usually associated with poor posture, chronic strain, trauma, or congenital deformity, which can be visualized by imaging. Severe asymmetry is usually a subluxation or dislocation of the atlantoaxial joint, which may cause a series of uncomfortable symptoms such as dizziness and numbness of the limbs, and requires surgical treatment if necessary. Once dizziness, limb numbness and other uncomfortable symptoms appear, you should consult a doctor in time for examination. Usually, if atlantoaxial joint asymmetry is found after the radiograph, you should actively cooperate with the doctor to standardize the treatment.
