[2] When growth at the condyle exceeds its normal time span, it is referred to as condylar hyperplasia.
In 1986, Slootweg & Muller devised a histopathological classification which allows the condylar tissues to be classified into specific categories.
[11] - Midline shift towards contralateral side - Posterior crossbite on contralateral side - Enlarged ramus, normal condyle - Supra-eruption of maxillary molars on affected side - Open bite - Midline shift (minimal to none) - Excessive growth in the condylar head - Possible open bite - Sloping rima oris with possible chin deviation Many treatment options exist for this type of condition.
This option, however, does include a person living with the facial asymmetry features all the way up until 18 to 19 years of age.
A procedure called condylectomy can also be done which involves removing part of the growing condyle to arrest any active growth.
[12] Sometimes condylectomy can be done in conjunction with articular disk repositioning and orthognathic surgery to treat patients with mandibular hyperplasia, such as shown by Wolford et al.[13]
