The frontonasal duct is a duct through which either frontal sinus drains into the nasal cavity.[2][3] Each frontal sinus opens into the frontonasal duct by an opening (the opening of frontal sinus or frontal sinus aperture[4]) on the inferomedial part[3] of the floor of the sinus.[4] The frontonasal duct passes inferior-ward[5] to open either[3] into the middle nasal meatus at the anterior end of[3] the ethmoidal infundibulum,[3][5][2] or into the anterior ethmoidal air cells (which then in turn drain into the nasal cavity).[3]
The duct is lined by mucous membrane.[citation needed]
