Figure A: Facial nerve anatomy. The facial nerve is responsible for facial expression. The facial nerve begins in the brainstem, then takes a course through the temporal bone of the skull, before dividing into multiple branches within the face.
Bell's Palsy. Causes of facial paralysis or facial weakness include trauma to the face or skull, a tumor in the head and neck, among other causes. Diagnosis of chronic facial paralysis is performed by a clinician, and may include electrodiagnostic testing in some cases.
Facial paralysis is a loss of facial movement due to nerve damage. Your facial muscles may appear to droop or become weak. It can happen on one or both sides of the face.
Bell's palsy causes sudden, temporary weakness in your facial muscles. This makes half of your face appear to droop. Your smile is one-sided, and your eye on that side resists closing. Bell's palsy, also known as facial palsy, can occur at any age.
Facial paralysis can make it difficult to speak, blink, swallow or smile. When facial paralysis does not resolve on its own, surgery can address the problem. Result after two stage cross facial nerve graft and Gracilis flap for smile restoration to correct right sided facial paralysis resulting from resection of acoustic neuroma.
Facial paralysis occurs when a person is no longer able to move some or all of the muscles on one or both sides of the face. In people who are otherwise healthy, facial paralysis is often due to Bell palsy. This is a condition in which the facial nerve becomes inflamed.
Facial paralysis occurs when a person is no longer able to move some or all of the muscles of the face. These muscles are responsible for vital functions such as eating, speaking, closing the eyes and expressing emotions. Facial paralysis may be caused by stroketrauma, tumors that press on the facial nerve, diseases that affect the facial muscles or infections that may cause temporary or permanent nerve dysfunction.
The term facial palsy generally refers to weakness of the facial muscles, mainly resulting from temporary or permanent damage to the facial nerve. When a facial nerve is either non-functioning or missing, the muscles in the face do not receive the necessary signals in order to function properly. There are different degrees of facial paralysis: sometimes only the lower half of the face is affected, sometimes one whole side of the face is affected and in some cases both sides of the face are affected.
Jump to content. Facial nerve paralysis is a condition in which the nerve that moves the muscles of facial expression no longer works properly. The most common cause of facial paralysis is Bell's Palsy, which is thought to represent a viral infection of the facial nerve. Most patients with Bell's Palsy make a full recovery, but in rare cases, the nerve can be permanently injured.
