The anterior superior alveolar nerve (or anterior superior dental nerve) is a branch of the infraorbital nerve (itself a branch of the maxillary nerve (CN V2)).[1] It passes through the canalis sinuosus to reach and innervate upper front teeth. Through its nasal branch, it also innervates parts of the nasal cavity.
Anatomy
Course and distribution
It branches from the infraorbital nerve within the infraorbital canal]
Nasal branch
It issues a
inferior nasal meatus and innervates the mucous membrane of the floor and anterior portion of lateral wall (as far superiorly as the opening of the maxillary sinus) of the nasal cavity. It ultimately emerges close to the root of the anterior nasal spine to innervate the adjacent portion of nasal septum.[2]
Communications
The nerve participates in the formation of the superior dental plexus[2] by looping posterior-ward to[citation needed] communicate with the middle superior alveolar nerve.[3]
The nasal branch communicates with nasal branches of the
sphenopalatine ganglion.[2]
