[The diagnoses and classifying of congenital craniofacial cleft].
OBJECTIVE
To diagnose and classify the congenital craniofacial cleft with a uniform scale is helpful to evaluate the abnormality and select the repairing methods.


METHODS
We analyzed 81 cases of congenital craniofacial cleft basically using Tessier craniofacial cleft classification. Furthermore, according to the position of soft tissue or bone, the character and degree of clefts or dysplasia and the results of CT scanning, we subdivided the congenital deformities based on S (skin), T (tissue), and O (OS). Arabic numerals were used to express the degree of the abnormality.


RESULTS
Of all the cases analyzed with the STO classification, No. III and IV clefts are often seen in the infraorbital region (24.70%). No. IX and X clefts are mostly seen in the supraorbital region (38.27%). The relationship between the cleft types and involved tissue has not been found.


CONCLUSIONS
The STO classification reinforces Tessier classification. It offers the basis for craniofacial cleft repair.
