Aim. This study was carried out to determine facial soft tissue thickness (FSTT) of adults according to skeletal class and to detect whether there is a statistical significance between groups. Material and Methods. The facial soft tissue thickness was measured both manually and digitally considering gender and age groups. The difference between the skeletal classes was compared after the obtained data were classified according to the skeletal classes. Results and Discussion. In our study, FSTT values of the males were found to be greater than those of the females. There was no significant difference in tissue thickness between the two sexes in glabella and nasion regions. In our study the values of FSTT were examined according to skeletal classes. In the skeletal class 3 group, the values of FSTT in the pogonion area were statistically lower than class 1 and 2 skeletal groups. In women with class 2 jaw structure, FSTT in the pogonion region was found to be significantly greater than those of Class 1 and 3 females. Also, men with class 2 jaw structure had significantly higher FSTT values in the labrale inferior region than those of class 1 and class 3 males. Conclusions. The FSTT can be affected by various factors such as skeletal class, age, bone structure, race and symmetry of the face.
