“…Our findings support the statement that the TMJ is related to facial morphology. Goulart et al [25] indicated that the condylar volume in subjects with mandibular prognathism was similar to subjects with unilateral condylar hyperplasia, concluding that the facial morphology in subjects with skeletal class III could be related to the presence of a bilateral condylar hyperplasia [26]. Likewise, our results show that the coronal distance of the condyle is significantly greater in subjects with skeletal class III, thereby supporting the previous conclusion of Goulart et al [25,26].…”

The aim of this research was to analyze the facial class, presence of malocclusion, and the mandibular plane and to relate this to the mandibular condyle position. A cross-sectional study in subjects under analysis for orthognathic surgery was done. The mandibular plane, the gonial angle, and the molar class were included to compare the coronal and sagittal position of the condyle and the joint space observed in the CBCT. The measurements were obtained by the same observer at an interval of two weeks. In addition, the Spearman test was performed to determine the correlation using a p value < 0.05 to observe any significant differences. Eighty-nine male and female subjects (18 to 58 years old, 24.6 ± 10.5) were included. In the coronal section, subjects with CIII had a greater mediolateral distance (MLD, p = 0.0001) and greater vertical distance (SID, p = 0.0001) than subjects with CII. In terms of the skeletal class and the mandibular plane, it was observed that subjects in the CII group had a greater mandibular angle (open angle) (p = 0.04) than the CII group and was related to the anterior position of the condyle. The most anterior condylar position was observed in the CII group (p = 0.03), whereas a posterior condylar position was significant in CIII subjects (p = 0.03). We can conclude that the sagittal position of the TMJ was related to the mandibular plane and the skeletal class showing a higher mandibular angle and most anterior position of the condyle in CII subjects and a lower mandibular angle and most posterior position of the condyle in CIII subjects. The implications for surgical treatment have to be considered.

“…The 3D volumetric depiction depends on the appropriateness of the segmentation, bone voxel threshold, and accurate suppression of surrounding tissue values to enhance the structure of interest. 35 Tecco et al, 36 Saccucci et al, 11 and Lin et al 37 have used the isolated condylar head by removing the condylar neck, considering that this area is well-associated with the growing mandibular process. However, their identification of the base of the condylar shape changing from ellipsoidal to circular cannot be accurately defined.…”

“…Changes in the volume of soft tissues are related to other disorders, such as metabolic bone pathologies, including CH that may involve changes in condylar anatomy. 11,12,23 Goulart et al 24 evaluated the condylar volume in patients with UCH compared to Class III malocclusion patients. They concluded that in UCH patients the affected condyle presented a higher volume than the contralateral condyle, while in the Class III group the condylar volume was equal for both sides.…”

Introduction: Facial asymmetry associated with unilateral condylar hyperplasia (UCH) is a complicated clinical condition. Objective: The objective of this study was to describe morphological characteristics of the mandible and the temporomandibular joint in patients with facial asymmetry, using computed tomography and 3D reconstruction. Methods: A retrospective observational study was performed with patients displaying facial asymmetry evaluated by single photon emission computed tomography (SPECT)/CT analysis, for suspected UCH, between 2015 and 2018. The following variables were compared between the affected side (producing the asymmetry) and the contralateral side (side to where the jaw is deflected): condylar length, condylar medial and lateral pole length, mandibular ramus length, intra-articular spaces, articular eminence height and position of the posterior wall of the glenoid fossa. Results: Forty-three patients (21 women, mean age: 20.7 ± 7.25 years) with facial asymmetry were included, 19 patients presented right side deviation and 24 patients had left side deviation. Condylar length, lateral pole length, the sum of maximum values and articular eminence height were greater in the affected side (p< 0.05). A positive correlation was found between the position of the posterior wall of the glenoid fossa and the articular eminence height in the affected side (r = 0.442). Conclusions: In patients with suspected UCH, evaluated through CT, craniofacial measurements showed significantly larger condylar length and the condylar sum of maximum values in the affected side. A positive correlation was found between the increased dimensions of the articular eminence and the more posterior position of the glenoid fossa in the affected side.

Comparative Evaluation of Condylar Volume Between Patients With Unilateral Condylar Hyperplasia and Class III Dentofacial Deformity

Abstract: Hyperplastic condyles were similar in volume to the condyles of patients with mandibular prognathism, suggesting that patients with a Class III skeletal relation could exhibit bilateral condylar hyperplasia.
