Objective:
To explore observing parameters of frontal sinus using reconstructive coronal nose bone sections of the head CT images and to establish the special identification codes.
Methods:
CT images of the frontal sinus were analyzed by using distance measurement and morphological description. The discrimination codes of frontal sinus identification were: the number of right partial septa, shape-the location of the central septa, shape-the number of left partial septa, shape; the number of arches of right upper scalloping (the location of the right highest scalloping, the location of the right lowest scalloping)-the number of arches of left upper scalloping (the location of the left highest scalloping, the location of the left lowest scalloping); the width, height of the right sinus-the total width of sinus-the width, height of the left sinus.
Results:
The identification codes of the frontal sinus were highly variable individually, but the codes were not statistically differences between males and females (P > 0.05).
Conclusion:
The identification codes of frontal sinus could be used for forensic individual identification, but not for sex determination.

The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
