Videomimicography: a new objective evaluation of facial motor fonction WANG De-sheng" Pavel Dulgueroo Willy Lehmann. • Departmetü of Otorhinolaryngology, Union Hospital, Affiliated to Fujian Medical University, Fuzhou 350001 , China Corresponding author , WANG De-sheng , Email
[email protected] [ Abstract] Objective To develop a new method, videomimicography(VMG) , to evaluate facial motor function. Methods During VMG, 11 landmarks were plaeed on the face, and 5 movements (forehead lifting, eye closure, nose wrinkling, lip puckering and smiling) with maximal contraction were requested. A digital video film was recorded then fed in a computer to he analyzed. Ten normal subjects were used as normal control. Results Area measures were found hetter than distance measures in evaluating facial movements. The hest measure for each movementwas determined. Then a global index of facial motor function was derived from these measures. This. index W8S found weil correlated with the facial paralysis House-Brackmann grade in 48 patients with facial paralysis (r = - O. 928). Conclusion VMG is an objective, quantitative, relative simple method. It has good reproducibility. 50 it can he used in clinic for evaluating facial motor function. [Key words] Facial paralysis; Facial muscles; Motion; Videotape recording
