At their base the maxillae carry the upper teeth and form the roof of the mouth. At the top, the maxillae form the floor of the orbits (sockets) of the eyes. Each maxilla contains a large air-filled cavity, called the maxillary sinus, which is connected to the nasal cavity. Incomplete fusion of the maxillae leads to cleft palate and hairlip.
