Bilateral horizontal hemicranial hypoplasia usually cannot be cured by itself, it may be caused by trauma, cervical spondylosis, viral infection, etc. It needs to be treated according to the specific cause of the disease such as medication, surgery, and so on. 1. Trauma: Trauma-induced bilateral horizontal hemicranial hypoplasia requires medication, such as diphenhydramine. This kind of drug has antihistamine effect, which can compete with the histamine released in the tissue for the H1 receptor on the effector cells and relieve the symptoms. 2. Cervical spondylosis: Cervical spondylosis can lead to insufficient blood supply to the brain, which in turn leads to bilateral horizontal semicircular canal function reduction. The symptoms of cervical spondylosis need to be improved, and after treating cervical spondylosis with traction or surgical resection, the function of the horizontal semicircular canal bilaterally will be restored. 3. Viral infections: Viral infections may cause inflammation of the vestibule, which can lead to bilateral horizontal hemicircular canal hypoplasia. After treatment with medications such as ribavirin and other antiviral medications, the inflammation disappears and bilateral horizontal hemicircular canal function is restored. Bilateral horizontal hemicircular canal hypoplasia cannot be cured on its own, so if bilateral horizontal hemicircular canal hypoplasia occurs, it is important to consult a doctor promptly.
