title: [Applied study on computerized quantitative facial nerve functional estimating system].
abstract: OBJECTIVE
  To prove the clinical applied value of quantitative facial nerve functional estimating system (QFES) by comparing the estimating results of the computerized QFES with manual QFES.
  
  
  METHODS
  50 volunteers with normal facial nerve function were used. Every volunteer was taken 7 photos with digital camera, which including static, and forehead wrinkle, eyebrows knit tight, eyes closed tight, nose wrinkle, smile, pout and mouth open to maximal seven expressions. The facial nerve function was estimated by computerized QFES, and the estimating results were compared with manual estimations by QFES in our study during 1991-1994.
  
  
  RESULTS
  All estimating indices in this study were in the range of 0.70-0.90 as well as the manual estimating results. However, the stand deviation in this study showed significantly smaller than the previous study.
  
  
  CONCLUSIONS
  QFES is an ideal quantitative facial nerve functional estimating system, after computerization the efficiency is increased and the systemic error is decreased. It will benefit to apply computerized QFES in the facial nerve function estimating fields.
