[Diagnostic / Planning]  Secondary Nasopalatine Canal??

Hey Dr. Kwon,

I was planning this case for 2 implants in #13/14 area on the CBCT and notice this canal which interferes directly with my placement of # 13

My first thought was a secondary nasopalatine canal? 

I did some research and found believe it to be a rare anatomical variation known as "Canalis Sinuosus", a small branch off the infraorbital canal. 

Have you encountered this before?

Any concerns, beyond some numbness if I obliterate the canal and graft it?

dear Stefano,

Thanks for the post.

Yes I encountered few of those during my 20 yr implant career.

No significant consequences. Sometimes more bleeding will be noticed during osteotomy. I havent had any significant or irreversible consequences.

Hope this helps,
