Abstract:
To investigate the development of the frontal sinus size during life, we studied the planar morphometry in 60 frontal radiographs of patients of different age and gender. A professional software (Bersoft Image 4.02) was used to measure the frontal area of the right and left frontal sinuses on radiographic images. A frontal sinus was already evident in 4-year-old children. Unilateral or bilateral absence of the frontal sinus was seen in 5% of cases. The size of the sinusal area increases up to 19-year-old patients, synchronous with general craniofacial growth. In adults, individual differences in size and shape occurred in relation to environmental factors. In some elderly patients, osseous resorption led to an enlargement of the frontal sinus that might complicate surgical procedures performed in this area.

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...

01:14Cranial Bones: Superior and Posterior View
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,...
