Four categories of skull shape have been established: CI up to 75.9, dolichocephaly; CI: 76.0-80.9, mesocephaly; CI: 81.0-85.4, brachycephaly; CI: 85.5 or above hyperbrachycephaly.
Hyperbrachycephaly occurred in 26%, whereas dolichocephaly in 22% of the children.
With the cephalic index in use, the skull shape may be defined as dolichocephaly, mesocephaly, brachycephaly, and hyperbrachycephaly. When the skull shape is determined, we need to take into account the fact that various authors apply various CI ranges when defining a specific shape.
