a hypoglossal canal with incomplete septum. The figure shows the right hypoglossal canal of a 40-year-old female. The canal is of type 3B, i.e., it has an incomplete septum. The arrow indicates the incomplete bony septum inside the canal. b hypoglossal canal with complete septum. The figure shows the left hypoglossal canal of a 40-year-old female. The canal is of type 4B, that is, it has a complete septum. The arrow indicates the bony septum that divides the canal into two symmetrical parts. c hypoglossal canal with complete septum. The figure shows the right hypoglossal canal of a 48-year-old female. The canal is of type 4B that is, it has a complete septum that divides it into two halves of very different caliber. This skull on the left presented a 4B canal with 2 equivalent holes. d distances of the internal hole of the hypoglossal canal from the anterior, posterior and inferior edges of the condylar process. The figure shows the distances between the inner edge of the hypoglossal canal and the anterior (IA), posterior (IP) and inferior (II) edges of the condyloid process
