Micrognathia:
Disorder of the upper or lower jaw is either real or relative:
Relative means:
** An abnormal or abnormal relationship between the two jaws (one of the jaws for the other) or an abnormal relationship between the jaws and the skull.
Example: The upper jaw, the lower jaw, makes the upper jaw move back with the skull.
True is either true:
Congenital Congenital:
Lack of development of the front of the upper jaw (Deficient Premaxilla) that carries the cutouts. It is mostly hereditary and unilateral. Accompanying:
* Dip in the chin.
* Absence or lack of growth.
* Small jaw angle.
** Acquired: Acquired:
Occurs in cases of temporal jugular adhesion due to trauma, infection or radiation.
The necessary condition for the small size of the acquired jaw is that joint adhesion occurs at the stage of the development of the jaws, ie, a maximum until the age of (18-20) years, because then the growth of the jaws will be completed and reach their final size.
