[Stafne defect as a rare anomaly of the lower jaw growth].

Defects in mandible growth are of undoubted interest for practical healthcare. During the diagnosis, for a more accurate diagnosis and differential diagnosis, it is necessary to understand the criteria for the norm and pathology of diseases of the jaw bones. Often in the body of the mandible at the level of the lower molars, slightly below the maxillofacial line, defects are detected in the form of a depression of the cortical layer towards the unchanged buccal cortical plate. These defects, being the clinical norm, need to be differentiated with many tumor diseases of the maxillofacial region. The literature sources indicate that the cause of these defects is the pressure of the capsule of the submandibular salivary gland in the area of the fossa on the lower jaw. Modern additional diagnostic methods, for example, CBCT and MRI, make it possible to identify a Stafne defect.
