Gesichtsregionen:
- Stirnregion (30%)
- Linke Jochbeinregion (30%)
- Rechte Jochbeinregion (30%)
- Kinnregion (10%)
Die klinsichen Kriterien sind:
- Area (0=not involved; 1=<10%; 2 = 10%-29%; 3 = 30%-49%; 4 = 50%-69%; 5 = 70%-89%; 6= 90%-100%)
- Pigmentierungsgrad (0 = absent; 1 = slight; 2 = mild; 3 = marked; and 4 = maximum)
- Homogenität (0 = absent; 1 = slight; 2 = mild; 3 = marked; and 4 = maximum)
Hinweis(e)
The MASI score is calculated by adding the sum of the severity ratings for darkness and homogeneity, multiplied by the value of the area of involvement, for each of the 4 facial areas.
The score ranges from 0-48. It can be used as a baseline and also for treatment follow up.
