Origin
The middle superior alveolar vein arises as a network of veins in the upper jaw (maxilla) situated along the lateral wall of the maxillary sinus. These might extend to drain the lateral incisors and canines.
Course
The venous channels ascend in the maxilla to reach the floor of the orbit and drain into the infraorbital vein coursing along the orbital floor.
Tributaries
There are no named tributaries.
Structures Drained
The middle superior alveolar vein drains the lateral wall of the maxillary sinus (extending towards the canine and lateral incisor teeth).
