先天性颅面裂隙畸形的诊断和分类

目的 对先天性颅面裂隙畸形进行分类和诊断，有利于区分畸形的部位和程度，为手术修复提供指导。方法 用Tessier颅面裂分类的基本方法，对81例先天性颅面裂隙畸形进行分析，再根据畸形发生的部位、性状、CT扫描等临床检查结果，按照受累的范围，选用S(皮肤)、T(皮下组织)、O(颅面骨)等字母组合表示畸形部位和性状，选用阿拉伯数字的大小表示畸形的严重程度，作为Tessier分类的补充。结果 以STO分类法分析81例病例，眶下方畸形以Ⅲ、Ⅳ号裂多见(24．70％)，眶上方畸形以IX、X号裂多见(38．27％)，各种组织的受累程度并未表现出一定的规律性。结论STO分类法是Tessier分类法的补充，可为颅面裂隙畸形的修复提供依据。

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.
