Study Notes

  • The pterygopalatine fossa is a cone-shaped depression in the skull.
  • It is located between the maxilla, sphenoid, and palatine bones.
  • The fossa contains the maxillary nerve and its branches, the pterygopalatine ganglion, and the maxillary artery and its branches.
  • The maxillary nerve passes through the foramen rotundum to leave the fossa via the infraorbital fissure.
  • The pterygopalatine ganglion provides parasympathetic innervation to the lacrimal and mucosal glands.
  • The maxillary artery separates into several branches within the fossa.
  • There are seven foramina that connect the fossa to other regions of the skull and facial skeleton.
  • The pterygomaxillary fissure, foramen rotundum, and pterygoid and pharyngeal canals are openings in the posterior wall of the fossa.
  • The inferior orbital fissure is a space between the sphenoid and maxilla bones.
  • The greater palatine canal and sphenopalatine foramen connect the fossa to the oral cavity and nasal cavity, respectively.
