What are the symptoms of facial neuritis?

Facial neuritis, also known as facial nerve inflammation or facial nerve paralysis, presents with diverse and noticeable symptoms. The main symptoms include: 1. Mouth deviation: Facial expression muscles become paralyzed, causing the corner of the mouth to droop. When smiling or showing teeth, the mouth noticeably pulls toward the healthy side. 2. Air leakage while speaking: Due to paralysis of the orbicularis oris muscle, patients experience air leakage when puffing cheeks or whistling. 3. Drooling: Paralysis of the buccinator muscle causes food to become trapped in the gums on the affected side, leading to excessive salivation. 4. Inability to close the eyes: The eye fissure widens and cannot fully close. When attempting to close the eyes, the eyeball rolls upward and outward, exposing the white sclera.
