Bell’s Palsy is a sudden, temporary weakness or paralysis of the facial muscles, usually on one side of the face. 

 

Cause        :  Inflammation or compression of the facial nerve (cranial nerve VII) often linked to viral infections.

 

Symptoms: Drooping of the face, drooling, difficulty closing the eye, inability to smile and sometimes loss of taste or   

                      increased sensitivity to sound, pain or discomfort around the jaw or ear.

 

For most people, Bell’s Palsy is temporary, and recovery happens over a period of weeks to months:

  • Mild Cases: Symptoms typically start improving within 2-3 weeks, with full recovery in 3-6 months.
  • Moderate to Severe Cases: Recovery may take longer, sometimes up to 9-12 months.
  • In rare cases, some people may experience residual weakness or other complications like synkinesis (unintended muscle movements).

85% of people recover completely within a few months.

 

15% may experience lasting effects, such as mild facial asymmetry or muscle stiffness.

 

BTX/A is used to treat facial asymmetry and muscle overactivity on the unaffected side, which often compensates for the weaker side.

 

🕒 Onset:
– Initial improvement: 3 – 5 days
– Full effect: 1 – 2 weeks

 

Longevity: Typically 3 – 4 months

 

Contraindications
  • Active Bell’s Palsy or recent onset (within 6 months, risk of asymmetry).
Pre-Treatment Advice
  • Consult neurologist for history of facial nerve issues.
Post-Treatment Advice
  • Monitor for asymmetry.
  • Avoid facial exercises for 48 hours.
