Maxillary Tuberosity (Tuberosity of Maxilla)

A protrusion of bone known as the maxillary tuberosity is the most posterior portion of the maxillary alveolar process.

Maxillary Tuberosity

• A notch called the hamular notch distinguishes the maxillary tuberosity of each maxilla from the neighboring pterygoid process of the sphenoid bone.
• On its lateral side, maxillary tuberosity is irregular for attaching with
  • The pyramidal process of the palatine bone.
  • The lateral pterygoid plate of the sphenoid occasionally.
• A few fibers of the pterygoideus internus get their origin from maxillary tuberosity.
• Directly superior to this is a smooth surface, which creates the anterior margin of the pterygopalatine fossa.

It has a groove, for the maxillary nerve, which is is directed laterally and a little superiorly and is constant on the orbital surface, with the infraorbital groove.
