Suffering from sensitive hearing in my ear after facial paralysis from trauma. Been few months. Test said Absent reflex. Can it heal or permanent?

Facial nerve palsy. A post-traumatic facial nerve injury can affect facial muscle function with paralysis and can affect the stapedial reflex, which tends to dampen the effects of loud sounds to the ear. If the facial paralysis resolves, then in time the stapedial reflex should improve. You need to give it 6-12 months to resolve. .
