Sequelae of facial paralysis will not get worse with time. Facial paralysis is a peripheral facial nerve paralysis caused by non-specific inflammation of the facial nerve. Patients who fail to use hormone therapy in time in the early stage and have diabetes and other underlying diseases that lead to poor nerve nutrition and recovery may still have symptoms of facial paralysis after three months, which can’t be completely cured and is called sequelae. Symptoms of sequelae are fixed and will not worsen with time, but other complications may occur. Because facial paralysis will lead to incomplete eyelid closure on the side of facial paralysis, as well as shallow nasolabial folds and crooked corners of the mouth to the opposite side, the patient’s cornea will still be exposed to the air when resting with the eyes closed, which is likely to lead to dry keratitis or corneal ulcers, and in severe cases, may even lead to blindness, and the patient will often have eye pain, tearing, and manifestations of infection. When the patient eats, food is easily left between the buccal mucosa of the mouth and the teeth, and leakage is easy to occur when drinking, and the symptoms still persist over time, and the patient sometimes feels that the symptoms have worsened, which are mainly caused by complications.
