Size and shape of soft-tissue facial profile: effects of age, gender, and skeletal class

Cleft Palate Craniofac J. 1997 Nov;34(6):498-504. doi: 10.1597/1545-1569_1997_034_0498_sasost_2.3.co_2.

Abstract

Objective: A method for the quantitative and qualitative analysis of the facial soft-tissue profile has been developed, and applied to analyze the pretreatment lateral head films of 240 orthodontic patients aged 8 to 14 years.

Methods: Patients were subdivided for sex, age, and skeletal class. To standardize for different facial sizes, soft-tissue profiles from nasion to pogonion were traced in polar coordinates without modifications of facial shape, and standardized for an equal skeletal vertical dimension.

Results: The method allowed a simple and rapid quantitative evaluation of soft-tissue profiles during facial growth. An approximate evaluation of the soft-tissue thickness at nose, lips, and chin was also possible. No particular mathematical knowledge was required at any step of the analysis.

Conclusions: Facial soft-tissue size and shape were influenced by age and sex, and to a minor extent by skeletal class.
