It is necessary for oral surgeons treating maxillofacial lesion to comprehend the facial shape three-dimentionally.
60 normal faces (30 males and 30 females) taken by moiré topography were analized quantitatively using a FACOM M 200 computer.
1. The left side of the face was higher than the right in both male and female.
The right-left difference of the upper portion of the face was greater than that of the inferior portion, however the difference of the lateral portion was greater than that of the mesial portion. The difference, which was about 4mm at most, should be regarded within normal limit at surgical treatment of the cheek region.
2. The right-left difference of the female face was greater than that of the male.
3. The right-left difference was a little over 1mm on the upper lip, so this length was regarded three-dimentionally within normal limit at surgical treatment of the lip region.
4. The skin surface at the infraorbital region was a little rugged in both male and female, showing variable skin slope.
5. The male nose was more protrudent than the female, but the male cheek was less protrudent than the female, showing a steep skin slope from the nose to the cheek in male.
6. Conversely, the female nose was less protrudent than the male, but the female cheek was more protrudent than the male cheek, showing a gentle skin slope from the nose to the cheek in female.
