Unilateral hyperplasia of the mandibular condylar process.: A histological, microradiographic, and autoradiographic examination of one case

Abstract

Unilateral hyperplasia of the mandibular condyle must be ascribed to a persistent or resumed activity of the precartilaginous cells of the condylar growth zone (Rushton, 1946). Normally the active formation of cartilage gradually comes to a stop at about 20 years of age. Simultaneously the replacement of cartilage by bone ceases. The bone then forms a continuous plate interposed between the cartilage and the marrow cavity. Inactive remnants of the prec.artilaginous layer persist and its cells may be aroused to new activity, as for instance in acromegaly (Rush-: $ The authors are indebted to Professor B. Engfeldt, Upsala, for valuable advice during the course of the investigation.

Unilateral condylar hyperplasia – A genetic link? Case reports

“…(1962) undertook a microradiographic, autoradiographic, and histological analysis of one case and showed conclusively an increase in vascularity affecting the upper posterior part of the condylar cartilage from whence the growth was commencing. [13] Based on these theories local circulatory problems, previous trauma, hormonal disturbances, abnormal leading, and cartilaginous exostosis have been suggested as possible etiological factors.

Surgical Management of Mandibular Condylar Hyperplasia Type 1

“…Trauma (27)(28)(29)(30)(31), infection (1,27,32,33), heredity (3,(34)(35)(36)(37)(38), intrauterine factors (28,39,40), and hypervascularity (38,41) have also been implicated as causative factors for CH type 1 and type 2. Approximately one third of bilateral CH type 1 cases have a familial history (34).…”
