What do they mean by Dolichocephalic and brachycephalic?
Humans are characterized by having either a dolichocephalic (long-headed), mesaticephalic (moderate-headed), or brachycephalic (short-headed) cephalic index or cranial index.
What is the difference between brachycephalic and Dolichocephalic?
The term brachycephaly, for example, describes individuals with a cephalic index greater than 81% and the skull shortened in its anteroposterior dimension. Dolichocephaly, on the other hand, consists of anomalies with a cephalic index below 71% and an elongated cranial vault.
What is Mesocephalic skull?
Adjective. mesocephalic (not comparable) (of a person or animal) Having a head that is not particularly short or long from front to back, relative to its width from left to right.
How do you measure orthodontic cephalic index?
The breadth of the skull is the distance between the most projecting points at the sides of the head, usually a little above and behind the ears. The cephalic index is the breadth multiplied by 100 divided by the length.
Is dolichocephalic head normal?
Dolichocephaly can develop in an otherwise normal developing skull when a baby spends too much time in certain positions. While some research suggests genetic factors are linked to craniosynostosis-related dolichocephaly specifically, the true etiology of the condition is not yet fully understood.
What is a normal cephalic index?
The Cephalic Index, also referred to as cranial ratio or cephalic ratio is the measurement that will be used to categorize your infants head shape. The CI is the measured width of the head divided by the length of the head multiplied by 100 and reported as a percentage. Scale for Cephalic Index (CI) Normal: 75 – 90 mm.

The cephalic index (CI) is the ratio of the biparietal diameter (BPD) to the occipitofrontal diameter (OFD). It is used in the evaluation and planning of surgical procedures in individuals with craniofacial abnormalities, in particular craniosynostosis.
What causes cephalic?
Cephalic disorders are not necessarily caused by a single factor but may be influenced by hereditary or genetic conditions or by environmental exposures during pregnancy such as medication taken by the mother, maternal infection, or exposure to radiation.
