Types of facial paralysis - peripheral vs central lesions facial weakness or paralysis may result either from (i ) a peripheral lesion of cn vii, the facial nerve, anywhere from its origin in the pons to its periphery in the face, or (2 ) a central lesion involving the upper motor neuron system between the cortex and the pons. A peripheral lesion of cn vii, exemplified here by a bells palsy. The seventh nerve was one among about four cranial nerves asked about in question 21. 2 from the first paper of 2014 (other involved were cn ix, cn xii, cn vii, cn vi). Facial paralysis supranuclear central lesions spare the forehead and brow peripheral lesions take out the whole hemiface. Facial (nerve) palsy is a neurological condition in which function of the facial nerve (cranial nerve vii) is partially or completely lost. It is often idiopathic but in some cases, specific causes such as trauma, infections, or metabolic disorders can be identified. Two major types are distinguished central facial palsy (lesion occurs between cortex and nuclei in the brainstem) and peripheral. a step-by-step guide to understanding the clinical features of facial palsy and how to determine whether it is caused by a upper or lower motor neuron lesion.
