Changes

<embedvideo service="youtube" Alignment="right">https://youtu.be/6e7oZqyEtNQ</embedvideo>When unilateral pharyngeal weakness is present, the midline raphe of the palate will deviate away from the weak side and toward the normal side on phonationor when eliciting the gag reflex.(1,2) This movement is usually dramatic. Minor movements of the uvula and trivial deviations of the midline raphe are not of clinical significance. Unilateral palatal weakness occurs most often in lateral medullary syndrome. Involvement of cranial nerves IX and X by a process involving the lower cranial nerves, e.g., the jugular foramen syndrome, is a less frequent etiology.
