Is there New Condylar Formation after Unilateral Partial Mandibular Condylectomy?

Facial asymmetry related to unilateral condylar hyperplasia is one of the facial deformities diseases, usually treated with TMJ surgery. The aim of this review is to define if condylar reparation is possible after partial resection of the condylar head and establish the conditions. We realized a search in Pubmed Central, Science Citation Index, Elsevier Science Direct Complete, Highwire Press, Springer Standard Collection, to find the studies realized in condylar reparation after condylectomy in humans and animals. The results showed poor information for both, human and animal model research. The information shows that condylar reparation is possible after condyelectomy, demonstrating similar morphology with the normal non-operated condyles. Functional load, age and surgery presented relation with condylar reparation.

Spontaneous Onset

Condylar hyperplasia (CH) is a rare, self-limiting process manifesting between the first and third decades of life. CH causes facial asymmetry and derangement of the occlusion. Management involves resection of the condylar head and orthognathic surgery. This paper describes the case of a 37-year-old woman with spontaneous onset of CH over a span of approximately 25 years. The condition was managed with resection of the condyle alone, which dramatically improved facial asymmetry and altered the occlusion within a few months of follow up. Orthodontic treatment was then carried out and the patient underwent orthognathic surgery after 3 years. The patient is currently satisfied with her appearance and function and there are no signs of recurrence.

Head Neck

Mandibular condylar hyperplasia is a relatively rare condition with uncertain etiology affecting the condylar head, neck and many a times body and ramus of mandible. The condition causes facial asymmetry, deviation of the jaw, occlusal derangements and articular dysfunction. Radiographic examination plays a critical role in establishing a correct diagnosis. Bone scintigraphy scan has been found to be effective in direct assessment of condyar activity which aids in proper treatment planning. Here, we report a case of unilateral condylar hyperplasia in a 31year old male patient which was diagnosed and corrected with the help of appropriate radiographic examination.

ABSTRACT A 29-year-old female patient with unilateral condylar hyperplasia (UCH) of the left side presented with facial asymmetry, maxillary transverse occlusal plane (MXTOP) cant, posterior open bite, and Class III relationship. Treatment consisted of proportional condylectomy of the left condyle for management of UCH, and fixed orthodontic treatment with intrusion of the left maxillary molars to correct the MXTOP cant and remaining chin point deviation (CPD). Proportional condylectomy with a 14-mm resection of the left condylar head improved the CPD from 11.5 mm to 7.8 mm and resolved the posterior open bite on the left side. However, it produced a Class II relationship on the right and left sides, posterior open bite on the right side, and anterior open bite. Fixed orthodontic treatment with 1.8-mm intrusion of the left maxillary molars using miniscrews corrected the MXTOP cant from 3.5 mm to 1.7 mm, reduced the remaining CPD from 7.8 mm to 3.7 mm, produced counterclockwise rotation of the mandible, and resolved the posterior open bite on the right side and the anterior open bite. After 16 months of total treatment, normal overbite/overjet and Class I relationship were obtained. Treatment results were well maintained after 5 years of retention. For the correction of UCH, it is important to determine the amount of condylar head resection and accurately simulate the correction of CPD and MXTOP cant through intrusion of the maxillary molars.

Condylar Hyperplasia

Condylar hyperplasia (CH) is a rare idiopathic condition affecting the mandibular condyle where the growth of the condylar head and/or neck continues beyond the normal growth period. This disorder presents clinically as facial asymmetry and occlusal discrepancy. Here, we present two cases of CH managed at our centers during the period between 2012 and 2017 with a successful outcome. We highlight the clinical presentation, investigation, and surgical management and give a brief literature review.
