Comparison of craniofacial measurements of young adult African-American and North American white males and females.

Surgical correction of craniofacial disfigurements depends for its success on precise knowledge of the craniofacial norms of the patient's racial/ethnic groups. The norms of North American whites should be restricted to patients of Caucasian origin and not applied to members of other races. This study therefore sought to determine differences in anthropometric measurements of the craniofacial complex between African-American and North American white subjects of both sexes and of similar age (18-25 years old).

Anthropometric proportion indices in the craniofacial regions of 73 patients with forms of isolated coronal synostosis.

The study group consisted of 73 North American patients (29 males and 44 females), aged between 0-5 months and 20 years, 26 with right, 33 with left, and 14 with bicoronal synostosis. Basic proportion indices were established in 5 craniofacial regions (cranial, facial, orbital, nasal, oral) calculated from 2 projective measurements [cranial: eu-eu, g-op; facial: n-gn, zy-zy; orbital: en-en, ex-ex; nasal: al-al, n-sn; oral: sn-sto, ch-ch (eu, eurion; g, glabella; op, opisthocranion; n, nasion; gn, gnathion; zy, zygion; en, endocanthion; ex, exocanthion; al, alare; sn, subnasale; sto, stomion; ch, chelion)] taken from the patients by the first author before surgery. These data were then compared with the anthropometric norms established for North American whites (Farkas LG.

International anthropometric study of facial morphology in various ethnic groups/races.

When anthropometric methods were introduced into clinical practice to quantify changes in the craniofacial framework, features distinguishing various races/ethnic groups were discovered. To treat congenital or post-traumatic facial disfigurements in members of these groups successfully, surgeons require access to craniofacial databases based on accurate anthropometric measurements. Normative data of facial measurements are indispensable to precise determination of the degree of deviations from the normal.

Anthropometric measurements of the facial framework in adulthood: age-related changes in eight age categories in 600 healthy white North Americans of European ancestry from 16 to 90 years of age.

The aim of this cross-sectional anthropometric study was to determine the age-related changes in the facial framework during adulthood in healthy white North Americans of European ancestry (261 male subjects and 339 female subjects). Five measurements, four horizontal and one vertical, defining the framework were taken from the skin and bony surface of the face in the maturation period (16-20 years) and in 10-year age categories of adulthood (21-90 years). As well, the thickness of the soft-tissue cover between these two anatomical levels was measured.

Proportion indices in the craniofacial regions of 284 healthy North American white children between 1 and 5 years of age.

The study's aim was to provide the normal range data on 81 anthropometric proportion indices of the craniofacial complex, separately in boys and girls between 1 and 5 years of age, supplementary to the previously published normal proportion values of the North American white population from 6 to 18 years of age. In the first age group, 17 or 18 boys and 18 or 22 girls were measured. In each age group between 2 and 5 years old, 30 boys and 30 or 31 girls were examined.

Age-related changes in anthropometric measurements in the craniofacial regions and in height in Down's syndrome.

This cross-sectional study analyzed age-related changes in normal and abnormal measurements of the head and face in three age categories in 115 Down's syndrome patients 1 to 36 years old. The frequency of normal measurements significantly surpassed that of abnormal ones in each category. Clinically, the key task was to ascertain differences between the youngest and oldest patients.

Surface anatomy of the face in Down's syndrome: age-related changes of anthropometric proportion indices in the craniofacial regions.

The purpose of the study was to determine the age-related changes in normal and abnormal proportion indices in Down's syndrome patients between 1 to 5, 6 to 15, and 16 to 36 years of age. Nine indices were analyzed in five craniofacial regions of 125 subjects: 70.2% to 79.

Differences between direct (anthropometric) and indirect (cephalometric) measurements of the skull.

This study sought to determine the relative reliability of indirect cephalometric measurements and direct anthropometric ones taken in norma frontalis of 25 dry adult human skulls. Six of the 11 linear projective measurements were singular and located in the orbital, middle, and lower parts of the face, with two from each part. Two of the five paired measurements were taken in the orbital region on both sides, and the other three were taken in the middle to lower face between the midpoint of the facial axis and the landmarks lateral to it.
