Anatomy Monday: Anterior Superior Alveolar Canal (???)


I’m going to start out this week’s canal as a challenge. I’ve come across two cases recently with canals that appear to be heading towards the maxillary canine. Based on my research and review of anatomy I concluded this was possibly the anterior superior alveolar canal.  After discussing this case with the anatomy instructor here, he suggested an accessory canal for the nasolacrimal canal or a branch of the anterior ethmoid.  If you have any suggestions or are awesome and know exactly what it is, please let me know. Thanks. 🙂

This canal is seen as a vertical radiolucent line with thin radiopaque borders in the area of the maxillary canine.  Being that I don’t see this often (twice that I can recall) I only have this one example. If you have some and would like to share, please send them my way.
