Lateral superior posterior nasal branches of maxillary nerve
Rami nasales posteriores superiores laterales nervi maxillaris
- Related terms: Lateral superior posterior nasal branches; Posterior superior lateral nasal branches
Definition
Lateral superior posterior nasal branches of maxillary nerve arise as a group of about seven nerves from the pterygopalatine ganglion inside the pterygopalatine fossa. These nerves pass through the sphenopalatine foramen inside the lateral wall of nasal cavity and end up innervating the mucosa and glands over the superior and middle choncha in the lateral nasal wall, and the posterior ethmoidal air sinuses.
Please note that the remaining nasal nerves that do not innervate the lateral wall, pass across the roof of nasal cavity to supply the medial nasal wall as medial superior posterior nasal branches of maxillary nerve.
