The cheeks are fleshy flaps that form the sides of the face. They are continuous with the lips in front and join at the nasolabial sulcus from the nose to the mouth. Each cheek contains skin, superficial fascia with muscles and structures like the parotid duct, buccinator muscle covered by fascia, submucosa containing mucous glands, and mucous membrane. The buccal pad of fat is most prominent in infants and lies deep to the masseter and in front of it, draining into lymph nodes below the jaw and around the ear.
