Posterior superior nasal nerves

The (medial and lateral) posterior superior nasal nerves are branches of the maxillary nerve (CN V2)[3]: 496  that arise in the pterygopalatine fossa[3]: 369–370  and pass through the sphenopalatine foramen into the nasal cavity[3]: 496  to innervate the nasal septum (the medial nerves), and the posterosuperior portion of the lateral wall of the nasal cavity (the lateral nerves).

Lateral posterior superior nasal nerves

The lateral posterior superior nasal nerves pass anterior-ward in the nasal cavity to be distributed to the posterosuperior portion of the lateral wall of the nasal cavity.[3]: 370
