• Most common cause of lower motor neuron (LMN) type of facial palsy is Bell’s palsy.
• Melkersson’s syndrome consists of a triad of : - i) Facial paralysis; ii) Swelling of lips; iii) Fissured tongue. Paralysis may be recurrent.
• As patient is unable to close the eye, eye protection is required to protect cornea and conjunctiva.
• The prognosis in acute facial palsy can be accurately determined by serial electrical testing. The response to electrical tests have been found to be most useful in the first 5 days after the onset.
