How long it takes for a young person to recover from facial palsy after treatment cannot be generalized, but depends on the specific cause of the patient’s facial palsy, as well as the severity of the facial palsy. Facial palsy, also known as nerve palsy, can be caused by many factors, such as stroke, tumor, infection, idiopathic facial nerve palsy, diabetic neuropathy, and trauma. Depending on the severity of facial palsy, it can be divided into two categories: incomplete facial palsy and complete facial palsy. Most of these patients can recover after timely and standardized treatment. Generally speaking, most patients with incomplete facial palsy can improve within a few weeks or 1-2 months of onset and recover completely within 3-4 months. In contrast, patients with complete facial palsy require more time to recover, ranging from 2-8 months or even longer. The prognosis is generally better after facial palsy in young people if not accompanied by the occurrence of difficult-to-treat diseases, such as tumors, while the prognosis is worse in the elderly or in people with combined underlying diseases such as diabetes, hypertension, atherosclerosis, and myocardial infarction.
