The following passages connect the fossa with other parts of the skull:
| Direction | Passage | Connection |
| Posteriorly | foramen rotundum | middle cranial fossa |
| Posteriorly | pterygoid canal (Vidian) | middle cranial fossa, foramen lacerum |
| Posteriorly | palatovaginal canal (pharyngeal) | nasal cavity/nasopharynx |
| Anteriorly | inferior orbital fissure | orbit |
| Medially | sphenopalatine foramen | nasal cavity |
| Laterally | pterygomaxillary fissure | infratemporal fossa |
| Inferiorly | greater palatine canal (pterygopalatine) | oral cavity, lesser palatine canals |
ContentsEdit
