Damage to facial nerve just above branching of chorda tympani causes all except:
Lesions within the facial canal distal to the meatal segment cause both hyperacusis and ageusio; lesions in the facial canal between the nerve to stapedius and the chorda tympani cause ageusia but no hyperacusis; lesions distal to the chorda tympani cause neither ageusia and hyperacusis.
Hyperacusis
Decreased salivation
Loss of taste from tongue
Paralysis of muscles of facial expression
