Epidemiology of facial clefts.

Epidemiology of facial clefts.

Data from the Glasgow Register of Congenital Malformations were used to investigate the epidemiology of congenital facial clefts over the period 1974-85. Facial clefts were registered in 247 infants representing a prevalence of 1.56 per 1000 total births. Cleft palate was more common than cleft lip, with cleft lip and palate occupying an intermediate position. More than half of the infants with...

Facial clefts in the west of Scotland in the period 1980-1984: epidemiology and genetic diagnoses.

Two hundred and eighty six cases of cleft lip, cleft palate, or both were identified in a study attempting complete ascertainment of babies with facial clefts born to women resident in the west of Scotland in a five year period beginning 1 January 1980. The total birth prevalence (TBP) of these defects over this period was 1.53 per 1000. The TBP for cleft lip with or without cleft palate (CL[P]...

EPIDEMIOLOGY OF OROFACIAL CLEFTS Doctoral (Ph.D.) – thesis

Regional facial asymmetries in unilateral orofacial clefts.

OBJECTIVES Assess facial asymmetry in subjects with unilateral cleft lip (UCL), unilateral cleft lip and alveolus (UCLA), and unilateral cleft lip, alveolus, and palate (UCLP), and to evaluate which area of the face is most asymmetrical. METHODS Standardized three-dimensional facial images of 58 patients (9 UCL, 21 UCLA, and 28 UCLP; age range: 8.6-12.3 years) and 121 controls (age range 9-12...

Oblique facial clefts: pathology, etiology, and reconstruction.

Modern views on embryology have increased our understanding of the nature of oblique facial clefts. The anomalies that have their origin at the junction of facial processes, such as the nasomaxillary dysplasias, may be named primary clefts or transformation. The maxillary clefts that are due to a developmental arrest of the skeleton are in fact secondary defects of differentiation defects. The ...
