In a LMN CN X palsy, does the uvula deviate toward the side of the lesion or away from the lesion?

In a unilateral LMN palsy of the vagus nerve, the muscles of the soft palate on the affected side weaken. The intact muscles on the opposite side pull the palate toward the normal side, so the uvula is drawn away from the lesion. Hence the uvula deviates away from the side of the lesion.
