Bell s palsy
C) When the facial nerve is injured, there's weakness in the ipsilateral upper and lower face. Illustration Brook wainwright Designs. Bells Palsy, bells palsy is an acute peripheral facial nerve palsy of unknown etiology, causing rapid onset of facial weakness. Its the most common cause of facial nerve injury.3 Deficits accumulate over hours to days, and reach maximum severity within three weeks. The symptoms may also develop at night while the patient is sleeping, making them seem more acute. Facial weakness typically recovers—partially or fully—within six months. Although Bells palsy can affect patients of any age, the median age of onset is 40 years, and its more common in patients in their third to fifth decade.1, 3,4.
Lesions that damage the motor cortex, such as acute ischemic strokes, will result in contralateral facial weakness of the lower face only, with preservation of the muscles of the upper face on both sides, due to the dual innervation of the upper face. Patients will have a weak smile, but will be able to close their eye tightly and wrinkle their forehead symmetrically. This pattern is often referred to as central facial weakness, because its caused by injury to the cerebral cortex, which is a part of the central nervous system. Lesions that damage the facial nerve in the brainstem, or after it exits the brainstem, result in ipsilateral facial weakness involving both the upper and lower face. It doesnt matter where truth the innervation is coming from; if the nerve is damaged, all the muscles on that side of the face are weak. These lesions are referred to as peripheral lesions because they affect the facial nerve as it exits the brainstem. Patients will be unable to wrinkle their forehead, tightly close their eye, or smile on the affected side. This distinction can aid in localizing the lesion to the appropriate place in the nervous system, thereby narrowing the differential diagnosis. Figure 1: Pathway of the facial nerve. A) The innervation to the muscles of the upper face originates on both sides of the brain, whereas the innervation to the muscles of the lower face comes from the opposite side of the brain only. B) When the cortex is injured, there's skin weakness in the contralateral lower face only.
and forehead movement, and fibers that supply muscles in the lower face, including the mouth. Can you tell the difference?

The fibers that control the lower face travel from the cortex down to the brainstem. In the brainstem, these fibers cross over to the opposite, or contralateral, facial nerve. The fibers that control the upper face take a slightly different path. After travelling down to the brainstem, half of the fibers cross over to the contralateral facial nerve, and half remain on the same side and contribute to the ipsilateral facial nerve. Therefore, the eyes and forehead receive innervation from both hemispheres, while the lower face only receives innervation from the contralateral hemisphere.2. Why does this matter? The strictly contralateral innervation of the lower half of the face and dual innervation of the upper half of the face is critical when assessing facial weakness.
Differentiating Facial weakness caused by, bells Palsy
You perform a neurologic baby exam; strength and sensation are normal throughout, with no weakness in the wrinkle arms or legs and no other neurologic findings. Shes able to communicate and answers all questions appropriately. Is this a stroke? Facial weakness, the two most common causes of acute facial paralysis are bells palsy and ischemic stroke.1 ems providers are often faced with the challenge of differentiating between these two diagnoses. Because acute stroke is a time-critical illness, the distinction between stroke and Bells palsy must be made quickly to avoid unnecessary delays in treatment. Anatomy of Facial Muscle control, two facial nerves, the right and the left, control all of the muscles in the face. The right facial nerve controls all of the muscles on the right side and the left facial nerve controls all of the muscles on the left side of the face. The facial nerves emerge from the middle of the brainstem (the pons) and carry motor fibers to the muscles of facial expression.
