Did facial palsy just steal your smile??? Let us handle the culprit right away.
There are two types based on the location of the casual pathology:
1. Central facial palsy
· Due to damage above the facial nucleus
2. Peripheral facial palsy
· Due to damage at or below the facial nucleus
Upper motor neuron causes are:
Lower motor neuron causes are:
Rare causes like Multiple Sclerosis, Guillain-Barre Syndrome, Otitis media, Neurosarcoidosis, etc
Diabetes, Pregnancy, Ear infection, Upper Respiratory tract infection and Obesity.
Paralysis of the muscles supplied by the facial nerve presents on the affected side of the face as follows:
Inability to close the eye
Lack of tear production
Inability to move the lips (e.g. into a smile, pucker)
At rest, the affected side of the face may "droop" except while the patient is in synkinesis. For example, voluntary movement of the mouth may result in the closure of the eye”
Ectropion - i.e. the lower eyelid may droop and turn outward
Hyperacusis - i.e. sensitivity to sudden loud noises
Altered taste sensation
Absence of horizontal lines on the forehead on the affected side
Affected eye larger/more open than the unaffected one
Lack of blink on the affected eye
Altered position or absence of the naso-labial fold on the affected side
Position of the affected corner of the mouth lower than the other side
Functional defects like:
-Difficulty eating and drinking as the lack of lip seal makes it difficult to keep fluids and food in the oral cavity
-Reduced clarity of speech as the "labial consonants" (i.e. b, p, m, v, f) all require lip seal
-Dryness of the affected eye
Physical Therapy management
Apart from the medical and the surgical management, Physical therapy plays a major role in patient education and in caring for the eye in the affected side by preventing corneal ulcer, use of eye lubrication and taping techniques.
Other PT treatment includes:
Neuromuscular retraining (NMR)
Electromyography (EMG) and mirror biofeedback
Trophic electrical stimulation (TES)
Proprioceptive neuro muscular facilitation (PNF) techniques
Neuromuscular re-education techniques have been found to be effective in increasing facial range of movement and symmetry, as well as reducing / minimizing synkinesis.
Mime therapy can improve functionality for patients with facial palsy
One study found that PNF technique is more effective than conventional exercises
One study found PNF and the Kabat technique is more effective than no exercise
The effect of electrical stimulation is controversial.
