Bell’s Palsy vs Facial Palsy

Bell’s Palsy vs Facial Palsy
(By Dr. Deepika Bansal – Physiotherapist in Balewadi, Wakad, Aundh, Pimple Saudagar)

Bell’s palsy and facial palsy both involve weakness of facial muscles, but their causes and patterns differ.

1. Bell’s Palsy

• Cause: Sudden inflammation of the facial nerve (often viral, e.g., herpes simplex).
• Onset: Rapid – within hours to 1–2 days.
• Type: Lower motor neuron lesion → affects both upper & lower face on one side.
• Symptoms:
  🔹 Inability to close the eye
  🔹 Drooping mouth
  🔹 Loss of taste on front of tongue
  🔹 Tearing or drooling
• Recovery: Usually complete within weeks–months with treatment and physiotherapy.

2. Facial Palsy (Generic Term)

• Cause: Any weakness of facial muscles due to various reasons – stroke, tumors, trauma, infections.
• Onset: Depends on underlying cause.
• Type:
  • Upper motor neuron lesion (e.g., stroke) → only lower face affected, forehead spared.
  • Lower motor neuron lesion → similar to Bell’s palsy.
• Symptoms: Vary depending on site of lesion and cause.
• Recovery: Depends on cause and nerve damage extent.

Key Difference
Bell’s palsy is a type of facial palsy, specifically idiopathic and acute, affecting the whole half of the face. Facial palsy is a broader term including all causes of facial weakness.

Physiotherapy helps in both through facial muscle exercises, massage, and electrical stimulation to restore movement and symmetry.
