Lateral posterior inferior nasal nerve

Last revised by Craig Hacking on 13 Oct 2022

The lateral posterior inferior nasal nerve is a branch of the greater palatine nerve that supplies the posteroinferior nasal lateral wall.

Gross anatomy

The nerve branches off the greater palatine nerve in the greater palatine canal and exits the canal though a tiny un-named foramen in the palatine bone to enter the nasal cavity. In the lateral wall of the nasal cavity it supplies the posterior inferior mucosa including the inferior concha and middle and inferior meati.

At the pterygopalatine ganglion it receives parasympathetic fibers which are carried by the greater palatine nerve before it branches off that supply nasal glands.

Variant anatomy

There may be a group of nerves, each entering the nasal cavity through numerous tiny foramina.
