The incisive canal ( incidere from the Latin, " cut ") is a bony canal in the hard palate of the people, which connects the oral cavity to the nasal cavity. His opening towards the oral cavity is the incisive foramen.

An open nasopalatine duct is a rare malformation in the front ( anterior ) upper jaw. The patent ductus nasopalatinus described in 1881 for the first time Hector Louis François Leboucq.

In the early embryonic forms in the primary palate within the incisive canal a paired, epithelialisierter transition as oro - nasal connection. Even before the birth of this transition includes in general and regresses. A persistence of the nasopalatine duct are considered malformation after birth must. In such a patent ductus nasopalatinus one or two small openings show the clinical side (lateral ) or ( posterior) behind the incisive papilla (see also ductus incisivus ) lie.
