2. INTRODUCTION
• Bell’s palsy is a paralysis or weakness of the
muscles on one side of the face due to damage
to facial nerve that controls muscles on that side
of the face . It is the most common neurologic
disorders of the cranial nerves .
• The symptoms may lasts from hours to days and
may become maximum within 3 weeks.Facial
weakness may be partially or fully disappears
within 6 months.The attack of bells palsy usually
seen after the age of 40.
3. BELLS PALSY
• Causes : In most cases nerve damage
is due to inflammation.
Herpes virus that causes cold sores.
7. Symptoms
• Acute onset of unilateral upper and lower facial
paralysis (within48-hr period
• Drooling.(flow of of saliva from the mouth)
• Eye problems such as excessive tearing or dry
eye.
• Loss of ability to taste.
• Pain in or behind the ear.
• Numbness in the affected side of the face.
• Increased sensitivity to sound.
9. • Epiphora
• Ocular pain
• Blurred vision
• Flattening of forehead and nasolabial fold on the
side affected by palsy
• When patient raises eyebrows, palsy-affected
side of forehead remains flat
• When patient smiles, face becomes distorted and
lateralizes to side opposite the palsy .
10. • Some may have permanent muscle weakness
or other problems on the affected side of the
face.
15. CLINICAL EXAMINATION
• Talk to the patient
Ask the patient about onset of the disease . “.
Bell’s palsy reaches maximum severity within
hoursto days.
Perform a brief neurologic exam. You want to
determine if the facial weakness is caused by a
peripheral or central lesion.
16. • Mouth: nasolabial fold—the wrinkle between the corner of
their nose and the corner of their mouth.
• Absence of nasolabial fold
• Unable to smile in severe cases
• In some facial weakness ,able to smile but absence of
nasolabial fold occurs.
• Mouth weakness may present in both central and peripheral
lesions.
17. • Diagnosis
• Examination for Bell palsy includes the following:
• Otologic examination: otoscopy and tuning fork
examination, particularly if evidence of acute or
chronic otitis media
• Ocular examination: Patient often unable to
completely close eye on affected side
• Oral examination: Taste and salivation often affected
• Neurologic examination: All cranial nerves, sensory and
motor testing.
18. • Eyes
Observe palpebral fissure,the distance between eyelid
margin.
Asymmetry in eyelid closure
Forehead: Ask the patient wrinkle their forehead, as if
they’re surprised. In peripheral lesion, the patient will
be unable to wrinkle their forehead on one side, or
have fewer wrinkles on that side.In central lesion, the
forehead should lift symmetrically, due to bilateral
cortical innervation of the frontalis muscle.
19. • In bell’spalsy only facial weakness on same side.
• The facial nerves emerges from the middle of the
brainstem (the pons) and carry motor fibers to the
muscles of facial expression.
• in brain stem damage the multiple cranial nerves may
also get affected including the motor and sensory tracts
travelling to spinalcord. So in brainstem ischemia also
facial weakness occurs.
• Weakness or numbness in the arm or leg
may be on same or opposite side due to the crossing
sensory and motor fibers in the brainstem.
20. • Slurred speech (dysarthria)-ask to say a few words
like “baseball player,” “fifty-fifty” and “tip-top.”in
addition to standard conversation .(brain stem
ischemia)

he two most common causes of acute facial paralysis are Bell’s palsy and ischemic stroke.1
Stroke
The innervation to the muscles of the upper face originates on both sides of the brain, whereas the innervation to the muscles of the lower face comes from the opposite side of the brain only. B) When the cortex is injured, there's weakness in the contralateral lower face only. C) When the facial nerve is injured, there's weakness in the ipsilateral upper and lower face. Illus
acute” facial Ischemic stroke is more acute in onset than Bell’s palsy and reaches to maximum severity within seconds to minutes. Patients often don’t know the exact time of onset, but family members, co-workers, or other witnesses may have more information. It’s crucial to determine the time they were last seen normal when assessing onset, rather than the time they first noticed the deficit.
diet therapy ,Add vitamins b6 ,b12,these may relieve symptoms of bells palsy.and improves nerve growth.
Apply moist heat .put cloth in warm water and apply for several times to reduce pain .
Face massage to restore the function and to reduce the discomfort.
Facial exercises
Meditation
Sticking needles at specific points to stimulate nerves and muscles
