Face paralysis

Face paralysis occurs when the muscles controlling facial expressions become weak or unable to move, often due to nerve damage or inflammation affecting the facial nerve (cranial nerve VII). This can result in one side of the face appearing droopy, losing movement, or having difficulty smiling, closing the eye, or other facial movements. Causes include infections, nerve injury, stroke, or conditions like Bell's palsy, which is a temporary nerve inflammation. Treatment varies depending on the cause and severity, and early intervention can improve recovery chances.
