Facial nerve palsy is a very complex group of diseases. Although most of them appear to be the same on the outside, the internal causes are very different. I often encounter BELL palsy, HUNT syndrome caused by herpes zoster, cholesteatoma otitis media facial nerve palsy, temporal bone fracture and maxillofacial trauma facial nerve palsy, Mero syndrome facial nerve palsy, facial nerve tumor facial nerve palsy, and so on. The treatment plan for facial nerve palsy differs from one cause to another, and the recovery time and results vary greatly. The incidence of BELL palsy is one of the highest among all facial nerve palsy, resulting in many patients with other causes of facial nerve palsy being treated as BELL palsy, and patients consume a lot of financial resources for nothing and experience a lot of meaningless and painful treatment. In BELL palsy, 85-90% of patients can recover well through conservative programs such as medication and physical therapy, but a small percentage of severe BELL palsy is difficult to recover by medication alone. Timely facial nerve decompression is an important method for this small group of patients. In the case of cholesteatoma otitis media, traumatic facial nerve palsy and facial nerve tumors, drug treatment is much less effective and a much higher percentage of these patients require surgery than BELL palsy. Current medical technology does not yet allow for one drug or one method to treat all cases of facial nerve palsy. You can’t go south on the road, and the same is true of seeing a doctor. Having a disease is not scary, as long as we have adequate and correct scientific knowledge, we have the real power to fight the disease in the face of it. May all my fellow patients regain their bright smiles.
