Facial Development

Retrospective studies into the effects of some aspects of treatment on facial development were based on x-ray films obtained in 58 men with unilateral cleft lip and palate operated on by palatal pushback. Because of mandibular retroposltion, individuals subjected to systematic orthodontic treatment had better sagittal jaw relations and occlusion of incisors than insufficiently treated patients. The retroposition was attained with orthodontic procllnation of upper incisors leading to a positive overjet and retraining the anterior development of the mandible. In patients with complete clefts operated on at about 6 years of age, sagittal jaw relations were more favorable than in those who had surgical repair at 4 years of age. The superior results in the group operated at a later age were due, in part, to the slighter retrusion of the maxilla. These differences were not apparent in incomplete clefts nor in patients with isolated cleft palate reported earlier. On the basis of these observations, a differentiated approach was proposed for determining the most convenient age for palatoplasty, according to individual types of clefts and their extent. The findings provided evidence of the essential role of orthodontic therapy for the configuration of the lower face in clefts.

Facial Development

Multifactorial cleft lip and palate is relatively common in populations (1 in every 700 livebirths). Individuals born with clefts require lifelong treatment after initial surgical repair and data suggested that their lifespan is shorter, possibly due to cancer or psychiatric conditions. Molecular defects that alter facial development in utero appear to later in life predispose to cancer. Common polymorphisms in e-cadherin and an endoplasmic reticulum transmembrane sensor gene appear to hold the promise to be biomarkers that may help to define individual risks to cancer, in the presence or not of family history of clefts.

Maxillary Arch

The focus of this study was an analysis of maxillary arch growth changes prior to the time of cheiloplasty up to 4 years of age. Serial dental casts were obtained and measured in 95 children with cleft lip and palate, or both: 7 unilateral cleft lip and alveolus (CLA), 52 unilateral cleft lip and palate (UCLP), 24 bilateral cleft lip and palate (BCLP), and 12 isolated cleft palate (CP). The children were treated at the Kyushu University Dental Hospital. The results are as follows: (1) Prior to cheiloplasty, the maxillary buccal segments in the subjects with cleft lip and palate showed lateral displacement. The premaxilla in BCLP subjects was protruded. (2) Cheiloplasty influenced maxillary anterior arch width, but not posterior width. The operation caused posterior displacement of the premaxilla in BCLP subjects. (3) Palatoplasty affected the growth of the maxillary arch in the transverse and anteroposterior dimensions. (4) A variety of growth patterns observed in the patients (e.g., increasing or decreasing of the maxillary arch dimensions) suggests that maxillary arch dimensions were affected not only by surgery, but also by other individual factors such as genetic facial pattern and severity of the cleft.

The incidence of dental abnormalities in the cleft lip and palate population has been reported to be much higher than in the normal population. The role of genes in the production of a cleft lip and palate, and dental anomalies is thought to be complex, with autosomal dominant, recessive, and x-linked genes all playing a role. Noncleft parents can carry some of the cleft lip and palate genes, which produce clinically subtle manifestations in their facial skeleton. The purpose of this study was to look for evidence of increased dental anomalies in the non-cleft parents of cleft lip and palate children. The dentitions of the parents of 60 children with different types of cleft lip and palate were examined prospectively to see whether or not they exhibited features found more readily in the cleft lip and palate rather than did the normal population. Their dentitions were studied to record the following dental features: congenitally missing teeth, supernumerary teeth, or morphologic changes of the crowns of the permanent teeth. The number and position of any frenal attachments were also recorded. The results of this study did not show any differences in incidence of dental anomalies from the noncleft population. There was no evidence to support the hypothesis that congenital absence of lateral incisors is a microform of cleft lip and palate. Further, these results also failed to reveal any consistent pattern in the number and position of frenal attachments.

Cleft lip and palate is one of the most common congenital anomalies requiring multidisciplinary care. Such anomaly is associated with many problems such as impaired feeding, defective speech, hearing difficulties, malocclusion, dental abnormalities, gross facial deformity as well severe psychological problems. Cleft of the lip and palate is one of the complex conditions that occur at a functionally potential area in the orofacial region and also at such a crucial time that strategic interventions at the right age by the concerned specialists becomes the need of the hour. Pediatric dentist is an integral part of the cleft rehabilitative process right from the neonatal period upto the phase of permanent dentition. Being well versed with a childs growth and development, both physical and mental, a Pedodontist helps in restoring function and esthetics in a cleft child, in a most empathetic way. This article describes the enormous challenges faced by these innocent souls and the vital role played by a Pedodontist, to provide comprehensive cleft care, be it preventive, restorative, or interventional care, in order to achieve the best possible outcome and meaningfully improve their quality of life.

Craniofacial malformations have been recorded since time immemorial. While observational studies have assisted in the recognition of syndromes, little light has been shed on the causal mechanisms which interfere with craniofacial development. Animal studies in which malformations occur spontaneously or have been induced by teratogenic agents have permitted step-by-step investigation of such common deformities as cleft lip and palate. The role of the ectomesenchymal cells of the neural crest and the possible phenomenon of disorganized spontaneous cell death are described in relation to lip clefts. The factors associated with isolated cleft palate, Pierre Robin syndrome and submucous clefts are described by reference to animal models. The haemorrhagic accident preceding the onset of craniofacial microsomia is discussed as is the distinctly different phenomenon of disturbance to the migration or differentiation of neural crest cells in the pathogenesis of Treacher Collins syndrome. The more severe anomalies of the calvarium such as plagiocephaly, Crouzon and Apert syndrome still defy explanation, in the absence of an appropriate animal system to study; some thoughts on the likely mechanism of abnormal sutural fusions are discussed.

Objective This paper reports on birth weight, body length, body mass index, and cranial circumference at birth of infants with cleft lip and/or palate born between 1973 and 1992. Methods Data were obtained from two nationwide swedish health registries. Infants with syndromes, twins, and infants with immigrant parentage were excluded from the study. Comparisons were made with all singleton births with the same exclusion criteria (n = 2,031,140). Results The body dimensions of infants with isolated cleft lip (n = 865) were found not to differ from those of control subjects, but infants with isolated cleft palate (n = 811) or cleft lip and palate (n = 1139) were found to be lighter and shorter than control subjects. Also, infants with the Pierre Robin sequence (n = 121) had a tendency to be lighter and shorter than control subjects, but these differences did not reach statistical significance despite the large study population.
