ABSTRACT True hemimandibular hyperplasia is an uncommon maxillofacial deformity. Patients with this affliction present clinically with varying degrees of asymmetry characterized by an increase in ramus height, a rotated facial appearance with kinking at the mandibular symphysis, and prominence of the lower border of the mandible. In the advanced form, maxillary and mandibular alveolar bone overgrowth result in a compensatory canting of the occlusal plane and a significant functional malocclusion requiring bimaxillary surgical correction. Nine patients with the above condition were treated with various surgical methods over a 9-year period. The clinical results were satisfying and the long-term results showed good postoperative stability. The pathology of hemimandibular hyperplasia is described and the preexisting nomenclature further defined.

    ABSTRACT: This case report demonstrates the successful treatment of facial asymmetry with condylar hyperplasia with limited surgical and orthodontic treatment. A high condylectomy was performed to shorten the elongated condyle and to remove its active growth site. The maxillary molars on the affected side were then orthodontically intruded using temporary anchorage devices to improve the occlusal cant and posterior open bite of the unaffected side. This combined surgical-orthodontic treatment provided a satisfactory outcome without additional orthognathic surgery. Copyright © 2015 American Association of Orthodontists.

    ABSTRACT: Condylar hyperplasia of the mandible is a clinical condition of over-development and growth because of excessive cellular growth of one condylar part of the mandible leading to facial asymmetry, mandibular deviation and enlargement of condyle. The elongation of the condylar neck in turn leads to malocclusion and articular dysfunction. In the past the interceptive and corrective procedures of growth and deformity in condylar hyperplasia were either condylectomy or high condylotomy. However, the deformity ceases after growth is completed. Therefore, other surgical procedures have to be undertaken to correct the manifested deformity of condylar hyperplasia. Further it has to be stressed that no single procedure can completely correct the deformity. So in addition to condylectomy, other orthognathic surgical procedures both on body and ramus and also on maxilla can be undertaken to correct the canting of occlusion. Two rare cases of unilateral hyperplasia encountered in our hospital are presented which required different lines of treatment.

    ABSTRACT: Unilateral condylar hyperplasia (UCH) is a disorder of unknown etiology mainly seen in growing patients, which results in facial asymmetry. High condylectomy alone or in association with orthognathic surgery can improve the occlusion and the facial aesthetics. Between 2005 and 2012, a total of 5 patients underwent high condylectomy for UCH using a piezoelectric cutting device. All patients were treated postoperatively with functional rehabilitation. The long-term follow-up showed that all patients had a satisfactory temporomandibular joint articular function associated with stable occlusion without any recurrence of further condylar growth. High condylectomy in the surgical treatment of unilateral UCH seems to be the procedure of choice in growing patients. The use of a piezoelectric cutting device allows a safe and less invasive high condylectomy.
