Detailed explanation-1: -Ask the patient to smile, show teeth, close both eyes, puff cheeks, frown, and raise eyebrows.
Detailed explanation-2: -Ask the patient to look up or wrinkle the forehead; inspect for asymmetry. Ask him or her to close the eyes tightly. Look for incomplete closure or incomplete “burying” of the eyelashes on the affected side. Observe the nasolabial folds and mouth while the patient is concentrating on the eyes.
Detailed explanation-3: -Most of the 43 muscles we use to smile are under the control of the seventh cranial nerve. This is also referred to as the facial nerve.
Detailed explanation-4: -5th Cranial nerve For the 5th (trigeminal) nerve, the 3 sensory divisions (ophthalmic, maxillary, mandibular) are evaluated by using a pinprick to test facial sensation and by brushing a wisp of cotton against the lower or lateral cornea to evaluate the corneal reflex.
