What is the term for cranial base lateral cephalometric measurement?

Sella-Nasion
Sella-Turcica
Nasion-A point
A point-B point

The correct answer is: Sella-Nasion

The term for cranial base lateral cephalometric measurement is referred to as Sella-Nasion. This is because the measurement is based on the distance between the sella point (the midpoint of the fossa hypophysis of the sella turcica) and the nasion point (the most anterior point on the frontonasal suture). The other options, such as Sella-Turcica, Nasion-A point, and A point-B point, are incorrect because they either refer to a specific point on the cranial base (sella or nasion) or are not specific enough to determine a lateral measurement.
