Abstract:
Obstructive sleep apnea and hypoapnea syndrome (OSAHS) is important to orthodontists for several reasons. The authors, after defining OSAHS and describing it briefly, review the literature dealing with the cranio-facial morphology of apnea patients. They report the results of their cephalometric study, which is based on an architectural analysis of 274 patients. Their facial characteristics, especially vertical dimension, are consistent with those displayed by mouth breathing children. Changes in respiratory functioning modify the mechanical behavior and the structures of the upper airways. Osseous tissues also show signs caused by these changes. The authors propose an etiopathogenic model.

Body Planes
The sagittal plane is the plane that divides the body or an organ vertically into right and left sides. If this vertical plane runs directly down the middle of the body resulting in equal division, it is called the midsagittal or median...

Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The long...
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...
Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
