THE FACE 



anterior-superior angle is prolonged obtusely. Inasmuch as the supe- 

 rior angles are bent inward, the bone appears to be bowed strongly 

 outward. The malar presents two principal surfaces, four borders, and 

 three processes. 



The external, or facial, surface (Fig. 283) faces downward and 

 outward. It has the general shape of the bone, and is bounded above

by the orbital and temporal borders ; behind by the temporal border ; 

 below by the inferior, or zygomatic, border ; and in front by the 

 anterior, or maxillary, border. It is divided into two parts by a 

 prominent masseteric ridge which arches upward and backward from 

 about the middle of the anterior border to the notch between the 

 two prominent posterior corners. The larger part, above this ridge, 

 is convex from before backward, and slightly concave from side to side. 

 Its curved, forward prolongation is called the maxillary process, and 

 the posterior extension is called the postorbital, or frontal, process, 

 and is sometimes united to a similar process projecting from the frontal, 

 thus forming a posterior boundary to the orbital rim. The part of the 

 external surface below the dividing ridge is flat and faces downward 

 and backward, and is continued posteriorly as the slender zygomatic 

 process. It gives origin to fibres of the masseter. 



The orbital border is strongly bowed outward. Through most of 

 its length it is sharp and slightly serrated and is the outer margin of 

 the orbit. Its anterior end is at first rounded and then bevelled for- 

 ward and downward toward the external surface, to form a small 

 triangular anterior surface. 



The maxillary border is rough and bevelled on each side, and fits 

 into the curved cleft in the malar process of the maxillary.
