part of the inner surface, articulate with the malar process 

 of the superior maxilla. The orbital border is excavated, and 

 forms a great part of the orbital margin, ending internally 

 just above or inside the infraorbital foramen. From this 

 the orbital process projects back, forming the forepart of the 

 outer wall, and enters the external portion of the floor of the

orbit, articulating with the great wing of the sphenoid and 

 orbital plate of the superior maxillary. On the orbital surface 

 are the openings of two canals the temporal opening on the 

 temporal surface, and the malar opening on the facial; they 

 transmit the temporomalar branches of the superior maxillary 

 nerve. 



The anterior extremity of the sphenomaxillary fissure may 

 be completed in one of three ways by the malar in more than 

 half the cases, by the articulation of the sphenoid with the 

 superior maxilla, or by a Wormian bone. 



The antrum of Highmore may extend into the malar.
