what does it serve?
what causes its paralysis?
• It controls the cheeks in blowing and sucking (an important muscle in the newborn).
• It serves to empty the gutter between the teeth and cheek during mastication.
• Paralysis of buccinator causes food to collect between the cheeks and teeth and an inability
to whistle.
• Note that the duct of the parotid gland pierces buccinator.
