Fracture line passes through the place of the frontal sprouts upper jaw with the nasal part of frontal bone on the inner wall of the orbit to the infraorbital fissure. Further extends anteriorly on the lower wall of the orbit to the infraorbital region, crossing his or skuloverhnechelyust Board the seam, or close to it. Then comes down and backwards on the front surface of the upper jaw, extending to the pterygoid bone sphenoid bone (sometimes on the border of the upper and middle third) (ris.3.7).

 The line is a fracture at the junction of the frontal sprouts upper jaw with the nasal part of frontal bone in her lattice notch. The front edge of the latter is connected to the nasal bones, and the rear – with the front edge of the plate perforated ethmoid bone, which is involved in the formation of the skull base in front of his pit. Rear bow sections of the frontal bone contains cells in contact with the ethmoid bone and forming the roof of its cells. Then the fracture line passes through the inner wall of the eye socket to the junction of the upper-and infraorbital slits, passes to the outer wall of the orbit, extending to her up and anterior to verhnenaruzhnogo its corner.
