ABSTRACT
The closed vertical subcondylar osteotomy (CVSO) of the mandible is accomplished with a wire saw. Through a systematic approach to anatomical landmark recognition and application of a very definite series of surgical maneuvers, the surgeon can achieve optimum results with little sequelae. Because the proximal segment resulting from this osteotomy is considerably larger than that produced in the closed subcondylar osteotomy, this procedure allows for a greater degree of movement (anterior, posterior and even rotational) of the distal segment. This added versatility permits the use of the CVSO in the treatment of aperthognathia, micrognathia, posterior open bite, and various combinations of these deformaties, as well as prognathia.

The complexities of the styloid-stylohyoid syndrome are examined from the historical, anatomical, radiographic, clinical and treatment aspects. Although approximately 4% of the population is afflicted with this anomalous growth, the syndrome is not usually seen clinically until after the age of 30. There appears to be little correlation between the size and extent of the anomaly and the predictability of patients having symptoms related to the anomaly. The awareness of the anomaly and the syndrome can lead to a proper diagnosis and the appropriate treatment for the patient who has been labeled by the dental community or medical community, or both, as psychoneurotic.
