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.

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.

ABSTRACT Facial asymmetry can be caused by unilateral condylar hyperplasia. In such cases, it may be difficult to achieve symmetry since there is dentoalveolar compensation on the affected side, and the occlusal cant does not correspond to the frontal mandibular deviation. In the case presented, surgical orthodontic treatment and orthognathic surgery planning was accomplished for a patient with facial asymmetry due to condylar hyperplasia. The surgical plan was devised with particular attention to the severe dentoalveolar compensation. In this case, prior to the two-jaw surgery, the occlusal cant and frontal mandibular plane inclination was corrected through impaction of the left molar region by segmental osteotomy. Facial asymmetry and severe dentoalveolar compensation were successfully corrected after a unilateral segmental osteotomy and two-jaw surgery, resulting in a stable occlusal relationship and facial symmetry as well as good jaw function. Collaboration between the orthodontists and maxillofacial surgeons was essential for the successful treatment of the patient.

Condylar Fractures

Condylar fractures in children are especially important because of the risk of a mandibular growth-center being affected in the condylar head, which can lead to growth retardation and facial asymmetry. The purpose of this article is to follow up the two and half year clinical and radiological evaluation of the conservative treatment of a 10 year-old patient, who had a unilateral green-stick type fracture. The patient presented with painful facial swelling localized over the left condylar region, limited mouth-opening and mandibular deviation to the left. Panoramic radiography and computed tomography confirmed the diagnosis of incomplete fracture on the left condyle with one side of the bone fractured and the other bent. Closed reduction was chosen to allow for initial fibrous union of the fracture segments and remodeling with a normal functional stimulus. A non-rigid mandibular splint was applied in order to remove the direct pressure on the fracture side of the mandible. Clinical and radiologic examination after 30 months revealed uneventful healing with reduction of the condylar head and remodeling of the condylar process following conservative treatment.

Facial asymmetry, following early childhood condylar trauma, is a common complaint among patients who seek surgical treatment. G.D.M., a 27-year-old male patient, sought professional help to correct his cosmetic flaw, caused by a condylar fracture when he was 8-years-old. After the proper orthodontic treatment, he underwent a double jaw orthognathic surgery and, 9 months later, a second one to correct the remaining asymmetry. Two years after this second procedure, the patient is still under surveillance and has no complaints.

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.

Variable Phenotype

Craniofacial microsomia (CFM) is a congenital anomaly with a variable phenotype. The most prominent feature of CFM is a predominantly unilateral hypoplasia of the mandible, leading to facial asymmetry. Even after correction of the midline, there is often a remaining hard- and soft-tissue deficiency over the body of the mandible and cheek on the affected side. This clinical report describes the skeletal augmentation of the mandible with a patient-specific implant to treat residual facial asymmetry in two female patients with unilateral CFM. Good aesthetic results were achieved in both patients treated with either a Medpor or polyetheretherketone implant without complications after a follow-up time of 55 and 30 months, respectively.

Gummy Smile

Two female patients presented with gummy smile, maxillary dentoalveolar protrusion and total vertical maxillary excess, retroclined incisors, and increased overbite received orthodontic camouflage with straight-wire mechanics by general dentists. The treatments caused severe bowing of upper occlusal plane which aggravated the gummy smile and had led them to seek specialist care. They were successfully managed by orthodontic camouflage and combined surgical-orthodontic treatment, respectively, in conjunction with the application of miniscrews on straight-wire mechanics. Aggravation of gummy smile by straight-wire mechanics, use of visual treatment objective to differentiate between orthodontic camouflage and surgical cases, and LeFort I segmentalization were discussed.
