Crooked head of a ten-year-old child may be caused by strabismus, strabismus, lymphadenopathy and other reasons. 1. Strabismus: It may be caused by muscular strabismus, bony strabismus, etc., resulting in head tilting to one side, i.e., tilting the head. 2. Strabismus: It may be caused by refractive error, etc., which makes the child’s vision unclear when he/she is looking straight ahead but relatively clear when he/she is looking diagonally, resulting in tilting of the head and squinting when looking at objects. 3. Lymphadenitis: Inflammation of lymph nodes caused by pathogenic bacterial infection, due to the stimulation of inflammation, lymph node swelling, pain and other symptoms, the patient’s head will be involuntarily turned to the affected side, resulting in tilted head phenomenon. It is recommended that a ten-year-old child with a tilted head go to the hospital in time, follow the doctor’s instructions for treatment, to avoid delaying the condition.
