“…In literature, there are studies which evaluate the frequency of mandibular asymmetries in three spatial planes using CBCT and show the importance of assessing them properly [13][14][15][16][17] . Baek et al (2012) 14 point out the importance of performing a systematic classification of asymmetries in patients who will undergo surgery using 18 report very similar measures between 2D and CBCT, although this latter technique offers more precision for locating anatomical points and more approximation to real morphometric measurements 19 .…”

Longitudinal differences on the left and right sides of the jaw with respect to the midline in three spatial planes are called mandibular asymmetries. Objective: To determine the frequency of mandibular asymmetries in three spatial planes by means of Cone Beam computed tomography (CBCT) and classify them according to the degree of difference between both sides. Methods: A total of 40 Cone Beam volumetric tomography (New Tom 3G Cone Beam Volumetric tomographic scanner) records were analyzed using simple random sampling of patients between the ages of 18 and 70 from 2011 until 2013. Axial slices were obtained from the lingula in cranio-caudal direction every 5 mm until the gonial angle. Results: From the records, 2.5% showed moderate degree of difference in the length of the mandibular body with predominance on the right side. For breadth of the ramus, predominance was found on the left side. In the length of the mandibular ramus, 10% presented moderate degree of predominance on the right side. Conclusions: 1) asymmetries are more frequent at the level of the mandibular ramus thickness; (2) moderate and severe degrees of differences are most frequently found in the mandibular ramus thickness. 3) It is not possible to proportionally determine mandibular ramus thickness only with a 2D image

“…La hiperplasia condilar consiste en el aumento del crecimiento condileo relacionándolo con el del lado opuesto. 31 Puede ser causante de asimetría mandibular y facial; se estima que es más prevalente en mujeres entre 15 y 24 32 años de edad, aunque pudiera afectar a cualquier individuo y a cualquier edad.…”

La tomografía computarizada Cone Beam es una herramienta que facilita el diagnóstico de diferentes alteraciones de la artculación temporomandibular mediante el escaneado y la obtencion del volumen especifico de la cabeza del paciente, generando resultados en 3D, con baja dosis de radiación comparada con los tomógrafos médicos, la cual permite cuantificar y cualificar los tejidos óseos sin distorsiones, con informacion detallada y precisa, para obtener diagnósticos confiables. El propósito de éste artículo es sitematizar la literatura reportada sobre el uso de la tomografía cone beam, como herramienta diagnóstica en pacientes con alteraciones temporomandibulares, contribuyendo como texto didáctico de referencia, proporcionando y resumiendo la información publicada sobre ésta nueva técnica. Se describen las características imagenológicas de cone beam de las diferentes patologías asociadas a la articulación temporomandibular, así como algunos criterios para la evaluación pre y pos tratamiento de la misma.

“…Morphological changes in the TMJ and facial morphology can be related [3] because the condylar volume is related to the size of the mandibular neck, ramus, or body-mainly in the growing stage [4]. In fact, facial asymmetry is strongly connected to the volumetric condition of the condyle [5].…”

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.
