The cranial perimeter of the small child

The cranial perimeter of the small child

Question:

- What perimeter of the skull should my child have at two months, with 6300 grams and the length of 62 cm, if it is possible to specify for both boys and girls in a table with specialized explanations. I mention that my boy with the body parameters indicated above has PC = 42 cm (41 cm - to the neurologist).

Answer:


The cranial perimeter is a faithful indicator of the growth process in the first two years of life. It is measured at the level of the frontal bumps and the occipital protuberance.
In the first year of life this parameter is important, because it can signal the presence of disorders: too small a cranial perimeter can mean microcephaly, premature closure of the fountains, while a too large cranial perimeter can be a sign of hydrocephalus or rickets - through late closing of the fountains.
There are tables with average values ​​of the cranial perimeter depending on age, waist, chest perimeter, but these are only indicative (being some statistical data) and must be interpreted in correlation with the clinical data.

Thus: a 2-month-old boy, according to statistical data, should have:

  • Height: 58.66 + 2.11 cm,
  • Weight: 5.35 + 054 kg
  • Skull perimeter: 39.09 + 1.32 cm
    Your little boy easily exceeds these values, but this fact has no pathological significance as long as no other changes are present.
    This is why these data are generally not useful to parents, but only to the doctor who can interpret them in a comprehensive clinical examination.
