Anatomy and Course
- The anterior superior alveolar nerve branches from the infraorbital nerve within the infraorbital canal.
- It enters the canalis sinuosus and passes towards the nose before branching into innervating branches for the upper/maxillary incisor and canine teeth.
- It usually innervates all the anterior teeth.
- A nasal branch passes through a canal in the lateral wall of the inferior nasal meatus and innervates the mucous membrane of the nasal cavity.
- The nasal branch also innervates the adjacent portion of the nasal septum.
- The nerve participates in the formation of the superior dental plexus.
- It loops posteriorly to communicate with the middle superior alveolar nerve.
- The nasal branch communicates with nasal branches of the sphenopalatine ganglion.

Communications
- The anterior superior alveolar nerve communicates with the middle superior alveolar nerve.
- It also communicates with the nasal branches of the sphenopalatine ganglion.

Anterior superior alveolar nerve (Wikipedia)

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)). 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.
