In the case of a crooked mouth, it is necessary to determine whether the crooked mouth is caused by central facial palsy or peripheral facial neuritis, which can usually be diagnosed after C-T or MRI examination of the head. If it is caused by ischemic stroke, it is recommended to give the patient symptomatic treatment such as antiplatelet aggregation, improving circulation, activating blood circulation and resolving blood stasis, etc. After the acute stage, the patient can also be given acupuncture to promote the recovery of central facial palsy. If the tilted mouth is caused by peripheral facial neuritis, the patient mostly has a history of exposure to cold. During the acute stage, the patient can be given hormones to reduce the edema of the facial nerve and apply nerve-nourishing drugs, such as vitamin B and methylcobalamin. After 7 days or so, acupuncture, cupping and bloodletting can be given to promote the recovery of the mouth. In about 1 month for peripheral facial neuritis, the patient’s crooked mouth can basically recover.
