The effects of unilateral discectomy and condylectomy on the contralateral intact rabbit craniomandibular joint. Intraorally, there is a collapsed maxillary dentition with severe crowding in the upper arch and moderate crowding in the lower Figure 4.

Am J Orthod Dentofacial Orthop. In the lower arch, 3 to 3 fixed retention was placed with twisted wire. In the upper arch, a circumferential retainer was placed. Bone scintigraphy as a diagnostic method in unilateral hyperactivity of the mandibular condyles: Decision to perform a condylectomy is made based on evidence of active changes in the hyperplastic condyle, or when observing clinical concilar radiographic suggestions of pathological conditions like: Nine subjects were included in this study 6 female and 3 male with an average age of UCH has been widely analyzed in recent years without obtaining any clear consensus in terms of etiology and diagnosis Olate et al.

Along with overcrowding it is among the main reasons for seeking an orthodontic consult. Slootweg Condular, Muller H. Contemporary treatment of dentofacial deformity. Bone scanning with technetium phosphate to asses condylar hyperplasia. The referral was due to the fact that this patient was in orthodontic presurgical protocol for laterognatia correction through orthognatic surgery.

Simple radiographic studies were carried out. Nevertheless, lack of maxillary lateral growth became evident, therefore it was decided to perform a Lefort I type osteotomy, gaining thus stable Angle Class I molar and canine occlusion, with dental and facial midlines in proper relation. The patient had no history of systemic disease, allergy, previous surgery, or use of continuous medication.

CBCT image of treated condyle 13 months after the procedure; clear areas of condylar regeneration are observed with sectors of cortical bone formation.

Hiperplasia condilar, diagnostico y manejo clinico a proposito de un caso clinico.

The preauricular incision is the most common approach to the TMJ, although other surgical approaches have been reported. Condylar morphology revealed the presence of a curved area similar to the morphology of a normal condyle, although with the smaller head Fig.


Prior to surgery routine laboratory analysis are carried out and additionally, a bone scan SPECT bone of the skull and facial massif with MDP-Tcm was requested to make sure that there was no active cell proliferation at the level of the condyle which could cause a relapse in the asymmetry and the laterognathia caused by the condylar hyperplasia on the right side.

Greater approach to the articular fossa was observed; the larger joint space reached 4. The purpose of this literature review is to provide detailed information on the behavior of this disease from the point of view of concilar etiology, clinical characteristics, and distribution by age, sex and affected condyle, as well as the necessary diagnostic and imaging aids for its diagnosis, differential diagnosis, associated diseases, histological characteristics of the affected tissues, and the different therapeutic approaches according to severity, patient’s age, and active or inactive form of the condition.

Prognatismo y laterognasia severos, hiperplasia condilar In the present case, and in all other cases managed by the surgical team, a preauricular incision is always the surgical approach of choice, because it provides sufficient visualization to perform the condylectomy ccondilar articular disc repositioning, even in this complex case of removal of a large hyperplastic condyle. We deem of the utmost importance condolar all patients presenting facial asymmetries to carry out a comprehensive study of its causes, and to consolidate a diagnosis that be not only dental, since TMJ alterations can be found like CH or other type of neoplasia.

CBCT image of hyperplastic condyle prior to surgery.

Asimetría facial secundaria a hiperplasia condilar mandibular: Reporte de un caso

The postoperative period was uneventful. Microcomputed tomographic analysis of human condyles in unilateral condylar hyperplasia: Elimination of transverse dental compensation is critical for treatment of patients with severe facial asymmetry. No warranty is hiperplaia about the accuracy of the copy.

TMJ radiographs and CT scans may show changes in the size and morphology of the mandibular condyle and condylar neck. If the maxillary plane does consilar follow the mandibular plane, on that side, an open bite will develop.

An ipsilateral sagittal split osteotomy should be performed to thrust the disc and the “new condyle” into the articular fossa. The CBCT at 1 month showed a clear and distinct slice of the condyle without defects or irregularities; the hiperplaasia from the condylar remnant to the articular fossa reached 8. Patients hipeprlasia exclusive condylectomy surgery with a piezoelectric system without disc replacement, orthognatic surgery or any other type of adjunct surgical procedure.


He reported that the mandible continued to grow, increasing facial asymmetry, and pain was felt at the right temporomandibular joint TMJ.

Services on Demand Article. The risk of recurrence of benign tumors is low after surgical removal. The surgical procedure hiperplasja potential complications, including damage to adjacent structures such as nerves cranial nerves V and VIIvessels, the ear, parotid gland, base of the skull, and middle cranial fossa.

The growth process is self-limiting, but as long as it remains active, asymmetry will progress along with associated occlusal alterations. In the present case, all the aforementioned methods were used for the diagnosis of CH. Clinically, the patients presented a chin deviation hieprplasia than 5 mm toward the contralateral side, with a posterior cross-bite and free of joint pain symptoms.

Prior to the withdrawal of the appliances, hipdrplasia braided. Access was obtained to the upper and lower joint spaces of the TMJ and condylar process, where a low condylectomy was performed with removal of approximately 8 mm of the condyle.

There was onset of pain in the left preauricular region as well as a decrease of oral opening, which was 20 mm when the patient arrived at hipperplasia hospital. In low condylectomy, the risk of injury to the maxillary artery is particularly high because the artery cpndilar posterior to the condyle and just above the sigmoid notch.

Our results showed that in the preoperative images, both segmented and volumetric, there were defined areas of cortical bone and cancellous bone. The treated condyles appeared 3.

Initial panoramic cindilar lateral radiographs. Histopathological and scintigraphic features of condylar hyperplasia. Regeneration of mandibular condyle following unilateral condylectomy in canines. The patient reported impaired sensitivity of the lower lip and complained of paresthesia, returning to normal 4 months after surgery.

The low condylectomy will remove all remnants of fibrocartilage from the condyle, resulting in the cortical and medullary bone of the condylar neck in juxta-approximation to the articular disc Wolford et al.
