Large vestibular syndrome generally refers to large vestibular aqueduct syndrome, usually due to congenital factors, trauma, and changes in environmental stress. 1. Congenital factors: most of the large vestibular aqueduct syndrome is due to congenital factors, due to the narrowing of the vestibular aqueduct during the miracle of embryonic development, resulting in developmental disorders leading to malformation of the inner ear, which needs to be considered in relation to genetic factors. 2. Trauma: If the patient has suffered trauma as a child, especially head trauma, it can also lead to large vestibular aqueduct syndrome if it affects the inner ear. 3. Environmental stress: A sudden and drastic change in external stress may also trigger Vestibular Canal Syndrome. There are many causes of Vestibular Aqueduct Syndrome, so it is recommended that patients go to the hospital in time and follow the doctor’s instructions for standardized treatment.
