Palate deviation

A phenomenon in which, when the palate is lifted, the midline deviates to the normal side and the weak side droops. Palate deviation is seen in individuals who have paresis or paralysis of a hemi-palate due to Vagus nerve injury or dysfunction. It can be observed from either the oral cavity or nasopharynx view; subtle cases sometimes seem easier to see from the nasopharynx view.
