AI 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 Abstract
Introduction: This study aimed to explore the distribution of deformational plagiocephaly in subjects with Class I skeletal pattern and the relationships of cranial vault asymmetry with menton deviation, condylar anteroposterior (AP) position and condylar angulation using cone-beam computed tomography images.
Methods: Approximately 135 pretreatment records of patients with skeletal Class I growth patterns from the University of Detroit Mercy were examined using Anatomage Invivo6 software. The midsagittal plane constructed by nasion, incisive foramen, and basion was used to evaluate the asymmetry of the cranium vault, condyles, and menton deviation. For each patient, the radiographic cranial vault asymmetry (RCVA) was calculated and compared against condylar and chin measurements: the horizontal condylar angle, AP positions of the condyles, and menton deviation.
Results: The Pearson correlation showed no direct correlation between RCVA and the mandibular variables (menton deviation and condylar measurements). The only mandibular variable that showed interaction with RCVA was the AP position discrepancy between the right and left condyles.
Conclusions: The severity of cranial vault asymmetry did not correlate to the asymmetry of the horizontal condylar angle, AP condylar position, and chin deviation. A tendency toward a relation between cranial asymmetry and AP positions of right and left condyles was observed.

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 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.
