An incisive canal courses through each maxilla. Below, the two incisive canals typically converge medially.[1]Each incisive canal transmits a nasopalatine nerve, and an anastomosis of the greater palatine artery and a posterior septal branch of the sphenopalatine artery.[1]Table of ContentsAnatomy[edit]Course and openings[edit]Contents[edit]Additional images[edit]See also[edit]References[edit]External links[edit]Anatomy[edit]An incisive canal has an average length of 10 mm, and an average width of up to 6 mm at the incisive fossa (the dimensions of the canal change with age, trauma, and loss of teeth).[1]Course and openings[edit]The two incisive canals usually (in 60% of individuals) have a characteristic “Y”-shaped or “V”-shaped morphology: above, each incisive canal opens into the nasal cavity on either side of the nasal septum as the nasal foramina; below, the two incisive canals converge medially to open into the oral cavity at midline at the incisive fossa[1] as several incisive foramina.[2]VariationThere are several alternative morphologies of the canals: the two canals may not converge at any point, may have multiple openings superiorly, or only a single canal (with one inferior as well as only one superior opening) may be present.[1]Contents[edit]Through each canal ascends the terminal branch of the greater palatine artery (to anastomose with the posterior septal branch of sphenopalatine artery) while the nasopalatine nerve descends (to anastomose with the greater palatine nerve).[3]Additional images[edit]Left maxilla.
