[Facial soft tissue three  dimensional morphometry].
OBJECTIVE
The purpose of this article were to assess the reproducibility of the landmark locating, and to obtain some facial soft tissue measurements data of the teenagers.


METHODS

RESULTS
No item of the remeasurement test showed statistical difference error. The sexual dimorphism was found in the measurements connecting with lower face height(Sn-Pg).


CONCLUSIONS
It indicated that the landmarks selected in this study had biologic significance and unique definition. The result of teenager facial measurements is in accordance with growth rule.
