What would be the consequences of the facial muscles in a dog were damaged?

Could you give me examples for the Masseter, Temporal and Buccinator.

If the muscles were partically severed, or torn, then the animal in question would recover. If they were severed completely, or if the tendons were cut, then they would not be able to move those muscles any more. As the muscles mentioned are used for chewing (mastication), partical tears would be an inconvience, but the dog would recover (albeit with great discomfort).What would be the consequences of the facial muscles in a dog were damaged?
Because these muscles are used for mastication, the dog would have problems chewing its food.
