Lower facial weakness can produce the appearance of tongue deviation when none is present because of distortion of the normal facial appearance. Manually pulling up the weak side of the face eliminates the “deviation.”
The tongue always deviates toward the weak side. (1,2) Whether this is toward or away from the side of the lesion depends on the specifics of the lesion. Because of the extensive interlacing of muscle fibers, the functional deficit with unilateral tongue weakness is usually minimal.

Lower facial weakness can produce the appearance of tongue deviation when none is present because of distortion of the normal facial appearance.

In a large series of patients with acute unilateral ischemic strokes above the lower brainstem, tongue deviation occurred in 29%, always toward the side of limb weakness. (3) In addition to weakness, nuclear and infranuclear lesions cause atrophy of the involved side. The tongue protrudes toward the weak side, which is also the side of the lesion.
Tongue weakness may result from a supranuclear, nuclear, or infranuclear lesions. Supranuclear lesions cause weakness but no atrophy, and the weakness is rarely severe. Since the genioglossus—the principal tongue protractor—has mainly crossed supranuclear innervation, the tongue protrudes toward the side opposite a supranuclear lesion.
