Detailed explanation-1: -Bell palsy is the most common peripheral paralysis of the seventh cranial nerve with an onset that is rapid and unilateral. This is an idiopathic condition causing partial or complete weakness of one half of the face along with changes in taste, sensitivity to sound and alteration in lacrimation and salivation.
Detailed explanation-2: -Facial nerve paralysis is an inability to move the muscles that control smiling, blinking, and other facial movements. This condition can affect a person’s ability to convey emotion. Most of the time, facial paralysis is limited to one side of the face.
Detailed explanation-3: -So, facial paralysis patients who forgo treatment can experience facial paralysis symptoms that last a lifetime. Comparatively, Bell’s palsy patients may regain facial function at any time without surgical treatment. In most instances, the symptoms of Bell’s palsy subside on their own without any permanent damage.
