title: Evaluation of some facial anthropometric parameters in an Iranian population: infancy through adolescence.
abstract: OBJECTIVE
  By finding the mean value of anthropometric parameters in normal samples of a population, it is possible to create a template for facial analysis. The aim of our study was to measure the anthropometric parameters in 0- to 12-year-old girls of Fars ethnic origin in the Northeast of Iran.
  
  
  METHODS
  Six hundred sixty-two newborn to 12-year-old girls of Fars ethnic origin participated in the study. A digital camera was used to take frontal full-face photographs of each child. Thirteen measurements were taken with the Smile Analyzer software: al-al, ch-ch, en-en, ex-ex, ft'-ft', go'-go', t-t, zy'-zy', n'-gn', n'-sn, t-g', t-gn', t-sn. Data were analyzed using the SPSS software at the significance level of 0.05.
  
  
  RESULTS
  In almost all parameters, we found significant growth acceleration between 2 and 4 years as well as 5 and 6 years of age. Another growth spurt was seen between 9 and 11 years, although it was less noticeable. Comparing the linear regression equations suggests that different craniofacial dimensions do not grow similarly.
  
  
  CONCLUSIONS
  By age, craniofacial dimensions change at different rates. Different craniofacial dimensions do not grow at consistent rates. Some parts grow slower compared with others. The intercanthal width has the slowest growth. Facial height shows the fastest growth.
