Background: Graber introduced facial photographs as an internal diagnostic aid. Facial photographs could serve as an important alternative assessment tool in the absence of equipment for cephalometric analysis.

Objectives: The present study was aimed at assessing whether analyzing the photographs could have precision for assessing the landmarks appropriate for facial analysis.
