“…Previous 3D studies have provided insight into growth of the facial skeleton in patients with CFM. 8,16–18,26 Similarly, studies using CBCT data have also characterized the distinct morphologies of dentofacial asymmetry. 11,33,44 Measuring asymmetric growth patterns in individual bones such as the mandible, however, remains challenging.…”

“…Several studies have measured mandibular growth in patients with CFM types I and IIA during adolescence using a combination of anteroposterior cephalograms, lateral cephalograms, and CBCT data. 8,14,15,18,19 These studies have conflicting results, with some 14,21,49 measuring the increasing cants of the mandible and the maxilla over time in the frontal plane, and others 8,15,18,19,22,50 reporting symmetric growth and no significant changes in facial proportions. Our findings favor the observations of symmetric condylar growth, and the preservation of mandibular proportions over time.…”

“…Although limited by only 2 time points, these results indicate potential compensatory growth of the dysplastic side. Examining models of the entire skull during growth, Shibatzaki-Yorozuya et al 18 showed that the condyle maintains its relationship with the articulating surface during growth, despite asymmetric growth of the cranial base. The observed difference in condylar growth direction could therefore be a compensatory response that preserves the condyle-fossa relationship.…”

Introduction Disordered craniofacial development frequently results in definitive facial asymmetries that can significantly impact a person's social and functional well-being. The mandible plays a prominent role in defining facial symmetry and, as an active region of growth, commonly acquires asymmetric features. Additionally, syndromic mandibular asymmetry characterizes craniofacial microsomia (CFM), the second most prevalent congenital craniofacial anomaly (1:3000 to 1:5000 live births) after cleft lip and palate. We hypothesized that asymmetric rates of mandibular growth occur in the context of syndromic and acquired facial asymmetries. Methods To test this hypothesis, a spherical harmonic-based shape correspondence algorithm was applied to quantify and characterize asymmetries in mandibular growth and remodeling in 3 groups during adolescence. Longitudinal time points were automatically registered, and regions of the condyle and posterior ramus were selected for growth quantification. The first group (n = 9) had a diagnosis of CFM, limited to Pruzansky-Kaban type I or IIA mandibular deformities. The second group (n = 10) consisted of subjects with asymmetric, nonsyndromic dentofacial asymmetry requiring surgical intervention. A control group (n = 10) of symmetric patients was selected for comparison. A linear mixed model was used for the statistical comparison of growth asymmetry between the groups. Results Initial mandibular shape and symmetry displayed distinct signatures in the 3 groups (P < 0.001), with the greatest asymmetries in the condyle and ramus. Similarly, mandibular growth had unique patterns in the groups. The dentofacial asymmetry group was characterized by significant asymmetry in condylar and posterior ramal remodeling with growth (P < 0.001). The CFM group was characterized by asymmetric growth of the posterior ramus (P < 0.001) but relatively symmetric growth of the condyles (P = 0.47). Conclusions Forms of CFM are characterized by active and variable growth of the dysplastic side, which has a distinct pattern from other disorders of mandibular growth.

The purpose of this article is to review and discuss the advances in the management of children born with cleft lip and palate (CLP) as it has evolved over the past 100 years. This overview is based on articles published in the American Journal of Orthodontics, which frequently changed its name, over the past century. Additionally, other journals will be cited as craniofacial anomalies became recognized during the 20th century and the biologic basis became refined, with the new discipline of genetics replacing the term hereditary and its connotations of eugenics. The Human Genome Project, completed in 2003, has now provided an understanding of syndromic and nonsyndromic CLP that has led to advances in the diagnosis and treatment of CLP in the 21st century. These evolving concepts will be discussed in an overview of the types of procedures published from 1915 to 2015 and the major transition in the mid-20th century from multiple uncoordinated interventions from various specialists to a coordinated team approach in which the orthodontist has a specific role in the timing and sequencing of interdisciplinary treatment goals. Major technologic advancements in treatment modalities and the contemporary approach to the health-related quality of life of the patient and the caregiver have resulted in their participation in treatment options and decisions. The requirement of informed consent reflects the legal doctrine that now emphasizes the ethical imperative of greater respect for patient autonomy in the decision-making process. The orthodontist no longer makes decisions alone, but rather with the team and the patient or the caregiver.
