What causes facial paralysis and mouth deviation?

Facial paralysis refers to facial nerve palsy, and mouth deviation refers to drooping or crookedness of the corner of the mouth. Facial nerve palsy can cause patients to develop a crooked mouth appearance. Causes of facial nerve palsy include infections, trauma, stroke, and others. A detailed analysis is as follows:

1. Infection

After the body is infected with pathogens such as bacteria, viruses, or fungi, the facial nerves may be damaged, leading to symptoms such as drooping of the mouth corner, inability to close one eye, drooling, and others. It is recommended that patients follow medical advice and use medications such as cefixime capsules or azithromycin dispersible tablets for treatment.

2. Trauma

Temporal bone fractures, facial injuries, or iatrogenic injuries may directly or indirectly damage the facial nerve. It is recommended to follow a doctor’s instructions and use medications such as mecobalamin tablets or mouse nerve growth factor for treatment.

3. Stroke

Conditions such as cerebral infarction or intracerebral hemorrhage may lead to stroke, which can result in neurological paralysis. Patients may experience facial nerve palsy, headache, nausea, and other symptoms. As this condition is serious, prompt medical evaluation is necessary. Treatment should be carried out according to medical guidance, and self-medication should be avoided.

Besides the above factors, conditions such as gastric cancer may also be related. Common symptoms of facial nerve palsy include mouth corner drooping, air leakage while speaking, and drooling. When these symptoms occur, it is advisable to seek timely medical attention and receive targeted treatment under a physician's care. During treatment, patients must strictly adhere to medical instructions.
