Introduction: Some clinicians believed that mandibular deviation leads to facial asymmetry and it also had a correlation with temporomandibular disorders (TMDs). Posteroanterior (PA) cephalogram was widely reported as a regular record in treating facial asymmetry and craniofacial anomalies. The objective of this study was to analyze the relationship of menton deviation in PA cephalogram with temporomandibular disorders (TMDs) symptoms.
Materials And Methods: TMJ function was initially screened based on TMD-DI questionnaire. PA cephalogram of volunteer subjects with TMDs ( = 37) and without TMDs ( = 33) with mean age of 21.61 ± 2.08 years was taken. The menton deviation was measured by the distance (mm) from menton point to midsagittal reference (MSR) horizontally, using software digitized measurement, and categorized as asymmetric if the value is greater than 3 mm. The prevalence and difference of menton deviation in both groups were evaluated by unpaired -test.
Result: The prevalence of symmetry group showed that 65.9% had no TMDs with mean of 1,815 ± 0,71 mm; in contrast, the prevalence of asymmetry group showed that 95.5% reported TMDs with mean of 3,159 ± 1,053 mm. There was a significant difference of menton deviation to TMDs ( = 0.000) in subjects with and without TMDs.
Conclusion: There was a significant relationship of menton deviation in PA cephalogram with TMDs based on TMD-DI index.

Purpose: This study aimed to quantitatively analyze temporomandibular joint (TMJ) space volume changes before and after bilateral sagittal split ramus osteotomy (BSSRO) with intended manual condyle positioning in patients with severe facial asymmetry.
Methods: A retrospective study was conducted, including 20 patients with facial asymmetry (menton deviation >8 mm) who underwent BSSRO with intended manual condyle positioning at a single institution. Cone beam computed tomography (CBCT) images were obtained preoperatively (T0), 2 days postoperatively (T1), and 6 months postoperatively (T2).

Article Synopsis
- The study investigated the occurrence of deformational plagiocephaly in patients with a Class I skeletal pattern, focusing on how cranial vault asymmetry relates to other skeletal alignment measures.
- Researchers evaluated 135 pretreatment records using advanced imaging software and assessed various anatomical measurements to determine any correlations between cranial asymmetry and mandibular features.
- Findings indicated no significant correlation between cranial vault asymmetry and most mandibular measurements, although some interaction was noted regarding the anterior-posterior positions of the condyles.

Article Synopsis
- The study aimed to evaluate facial asymmetry following bimaxillary surgery in patients with mild craniofacial microsomia (CFM) compared to those with non-syndromic class II asymmetry.
- Cone-beam CT scans were used to analyze the lower facial asymmetry in three groups: mild CFM, non-syndromic class II asymmetry, and normal controls, revealing that both CFM and class II groups had more significant asymmetry than controls.
- Post-surgery, while no major differences in certain asymmetry metrics were found between CFM and class II groups, CFM patients showed greater vertical contour asymmetry, highlighting ongoing challenges in correcting these features in CFM patients.
