Abnormal craniofacial growth

Acta Odontologica Scandinavica, 1995
Treatment of patients with craniofacial (CF) anomalies necessitates knowledge about normal CF growth and how it deviates in the abnormal state. There are different basic types of CF anomalies and various kinds of aberrations that influence CF development. These factors might help to explain why patients display growth variations.

Tcof1/Treacle is required for neural crest cell formation and proliferation deficiencies that cause craniofacial abnormalities

Proceedings of the National Academy of Sciences of the United States of America, 2006
Neural crest cells are a migratory cell population that give rise to the majority of the cartilage, bone, connective tissue, and sensory ganglia in the head.

The genetic basis of craniofacial and dental abnormalities

Schweizer Monatsschrift fur Zahnmedizin = Revue mensuelle suisse d'odonto-stomatologie = Rivista mensile svizzera di odontologia e stomatologia, 2011
The embryonic head development, including the formation of dental structures, is a complex and delicate process guided by specific genetic programs. Genetic changes and environmental factors can disturb the execution of these programs and result in abnormalities in orofacial and dental structures.

The application of molecular genetics to detection of craniofacial abnormality

Development, 1988
ABSTRACT Congenital malformations such as secondary cleft palate can be exclusively monogenic or polygenic, but most cases have a multifactorial origin involving both environmental and genetic factors, making genetic analysis difficult.

Diagnostic approaches to respiratory abnormalities in craniofacial syndromes

Seminars in Fetal and Neonatal Medicine, 2021
Craniofacial syndromes are a complex cluster of genetic conditions characterized by embryonic perturbations in the developmental trajectory of the upper airway and related structures. The presence of reduced airway size and maladaptive neuromuscular responses, particularly during sleep, leads to significant alterations in sleep architecture and overall

Abnormalities of craniofacial development: discussion report

Development, 1988
ABSTRACT The following topics arose as major areas of discussion after individual papers and in the general discussion at the end of the session. Discussion from both sources has been merged here to facilitate easier reading.

Syndromes of Abnormal Craniofacial Contour

2001
Abstract Anencephaly is a congenital anomaly characterized by an open neural tube in the cephalic region with an exposed mass of degenerate neural tissue on the skull floor. The cranial vault is absent, producing characteristic bulging of the eyes and absence of the neck.

Abnormal craniofacial development in cyclopic salmonid fishes

Journal of Morphology, 1992
AbstractDifferent types and degrees of “spontaneous” and artificially induced cyclopic malformation in fishes are defined. Symmetrical cyclopia ranges from approximation of the eyes, to partial merger of the eyes in the midline, to complete cyclopia with a single median eye.

Abnormal Coagulation during Pediatric Craniofacial Surgery

Pediatric Neurosurgery, 2001
<i>Introduction:</i> This prospective study of children undergoing major craniofacial surgery was undertaken to determine whether abnormal hemostasis occurred and to characterize any coagulopathy found. <i>Methods:</i> Coagulation tests, blood loss and blood product transfusions were recorded perioperatively.

Structural Abnormalities of the Craniofacial Complex and Congenital Malformations

Pediatric Clinics of North America, 1991
This article was meant to be a very cursory survey of the multiple defects that abnormal development can produce in all areas of the craniofacial complex. Careful examination for these abnormalities should lead the clinician to earlier referral of patients for additional examination by a genetics team.
