What are robin nmeasurements?

Robin measurements are a set of measurements used to assess the size and shape of a child's head. They are named after the British physician John Robin, who first described them in 1892.

Robin measurements include:

* Head circumference: This is the measurement of the circumference of the head, taken at the widest point.

* Frontal circumference: This is the measurement of the circumference of the forehead, taken at the widest point.

* Bitemporal diameter: This is the measurement of the distance between the two temporal bones, taken at the widest point.

* Occipitofrontal diameter: This is the measurement of the distance between the occiput (the back of the head) and the glabella (the point between the eyebrows), taken with a head circumference tape.

* Parietal diameter: This is the measurement of the distance between the two parietal bones, taken at the widest point.

Robin measurements are used to track a child's head growth and to identify any abnormalities. They are also used to diagnose certain conditions, such as hydrocephalus (an excess of fluid in the brain) and microcephaly (a condition in which the head is smaller than normal).
