Introduction:
Analysis of human faces and their dimensions plays a very important role in general medicine and dentistry, both in diagnosis and treatment planning.

Aim of the study:
To analyse the facial proportions of young Polish males and compare them with those of young Polish females and with the so-called golden ratio.

Material and methods:
A total number of fifty en face photographs of young Polish males (average age of 18 years) were examined. The images were taken by the same photographer with the same digital camera following a standardized procedure. Single and dual anthropometric points were set, and both the horizontal and vertical distances between them were measured using Adobe Photoshop software. Eleven correlations between the distances were statistically analysed, of which seven were vertical, three horizontal, and four vertical–horizontal correlations. The data acquired in this manner were compared to the golden ratio and to data from studies in the literature which employed the same methodology to examine the faces of young Polish females.

Results:
The average ratio of the nasion–stomion length and the stomion–gnation length in males was very close to the golden ratio, at precisely 1.648. For the nasion–subnasale and subnasale–gnation segments, this ratio was 0.780, differing considerably from the golden ratio. Statistical analysis showed significant differences in seven out of eleven average values of male facial proportions, as compared to data collected from females.

Conclusions:
Facial dimensions and proportions of Polish males differ from those of Polish females, although they are both close to the golden ratio when the vertical dimension is considered.
