Facial palsy is a disease that seriously affects the face, especially in young patients who are under tremendous mental stress once they have this disease. Although most patients can heal themselves, nearly 30% of patients will have lifelong regrets if they are not treated properly, that is, they will not only fail to recover, but also leave the sequelae of facial palsy, which will have an immeasurable impact on their lives. How to avoid this tragedy and make these patients get the best and most appropriate treatment as soon as possible is a problem for many patients, however, in the hesitation and uncertainty a few months will pass and it will be difficult to recover if the best treatment time is missed. Our hospital has recently introduced the most advanced facial nerve examination instrument, which can give the most authoritative conclusion on whether a patient with facial palsy should choose surgical treatment, and whether different treatments have improved facial function. Surgical decompression therapy can help patients with severe facial palsy to restore their facial function to the greatest extent possible. The surgery has no sequelae, does not affect hearing, and the minimally invasive surgical incision has no impact on appearance after surgery.
