Introduction:

Photogrammetry is the process by which measurements are obtained from a photograph. To take a correct photographic shoot, it is very important to standardize the technique in order to obtain reliable and reproducible records. One of its requirements is to define the position of the head. Thus, an incorrect posture can lead to errors in diagnosis and treatment planning.

Objective:

Establish a clinical protocol to standardize photographic registration and patient positioning for facial photogrammetry.

Materials and methods:

Standardized facial photographs were taken to a total of 163 students. 76 students had direct and indirect facial measurements. 87 students had their Natural Head Position compared at 3 times of the day. The results were statistically compared.

Results:

When applying a standardized protocol, there was no statistical difference between direct and indirect measurements, nor when comparing the head position of each student.

Conclusion:

The standardization of the photographic set exposed in this work is valid for making reliable and useful records as a complementary examination using the Natural Head Position, which allows to maintain a reliable and stable position over time.
