Purpose:
To investigate the relationship between upper airway and cranial-facial growth pattern among teenagers with normal occlusion.
Methods:
The study subjects consisted of 52 boys and 64 girls with normal occlusion. Their cephalometric radiographs were obtained. The sagittal diameter of upper airway was analyzed according to gender and different growth pattern. The relationship of upper airway diameter and cranial-facial formation was evaluated by stepwise regression analysis using SPSS 21.0 software package.
Results:
There was no significant difference between male and female about upper airway diameter in teenagers, also no difference was found among different growth patterns. Regression analysis showed that upper airway was associated with some cranial-facial formation parameters.
Conclusions:
Although there is no significant difference in the upper airway diameters among different growth patterns, there is still certain association between cranial-facial formation and upper airway in adolescents.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
Cranial Bones: Lateral View
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...
Cranial 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,...
