Hyperplasia of the condylar process is a disease with an unexplained etiology, characterized by a constant and accelerated growth of the condylar process, when its growth should be minimal or complete. Growth ultimately stops on its own.
Symptoms of hyperplasia of the condylar process
Slowly progressive one-sided increase in the size of the head and neck of the condylar process causes a cross bite, asymmetry of the face and displacement of the chin to the healthy side. The patient may develop an excessive upper jaw. The margin of the lower jaw is more convex on the side of the lesion. Chondroma or osteochondroma can give similar symptoms and syndromes, but they grow rapidly and can cause a larger increase in the condylar process.
Diagnosis of condylar hyperplasia
When X-ray examination, the temporomandibular joint may seem normal or the condylar process can be proportionally increased, and the neck of the process is lengthened, CT is usually performed to determine the end of bone growth that confirms the diagnosis, or localizes it in the region of the capillary process. If growth is limited, there is a need for a biopsy to differentiate the tumor and hyperplasia.
How to examine?
Treatment of hyperplasia of the condylar process
Treatment usually involves the removal of the condyle during a period of active growth. If growth stops, orthodontic and surgical treatment is performed to restore the lower jaw. With a significant increase in the size of the lower jaw, the asymmetry of the face can later be altered by reducing the lower edge of the jaw.
