| Abstract: | Objective: To test the reliability of 3 dimentional (3D) laser surface scanner for nasal anthropometry.Methods:11 plaster nasal models were measured by 3D laser surface scanner and manual measurement. The data were statistically analyzed. Results:In 9 out of the 10 parameters of nasal anthropometry,the correlation coefficient of the distances and angels measured by the 2 means was 0.856-1.000(P<0.01);in the parameter of nose pillar width that was 0.596 (P=0.053).When the digital images were 2 times magnified by SURFACER software to increase the clarity of dot cloud,the correlation coefficient of all the parameters was 0.804- 0.999 (P<0.01). Conclusion: 3D laser surface scanner is reliable for nasal anthropometry. |
