Classification and diagnosis of congenital craniofacial cleft deformities are helpful in discerning the severity of the deformity and providing guidance for surgical repair. Eighty-one cases of congenital craniofacial cleft deformity were analyzed using the Tessier classification. Depending on the location, status of the deformity, and results of examinations such as computed tomography, according to the range affected, the location and status of the deformity were designated by the STO classification, with S for skin, T for soft tissue, and O for os (craniofacial bone). The severity of the deformity is delineated by Arabic numerals. The analysis of 81 cases by the STO classification method showed that suborbital deformities mainly were Tessier 3 and 4 clefts (24.70%) and supraorbital deformities mainly were Tessier 9 and 10 clefts (38.27%). There was no definite regular pattern for the affected extent of tissues. STO classification can be a supplement to Tessier classification and can provide references for the surgical repair of craniofacial cleft deformity.
先天性颅面裂畸形的分类与诊断有助于辨别畸形的严重程度，并为手术修复提供指导。采用Tessier分类法对81例先天性颅面裂畸形病例进行分析。根据畸形的位置、状况以及计算机断层扫描等检查结果，依据受累范围，用STO分类法对畸形的位置和状况进行命名，其中S代表皮肤，T代表软组织，O代表骨骼（颅面骨）。畸形的严重程度用阿拉伯数字表示。采用STO分类法对81例病例分析显示，眶下畸形主要为Tessier 3和4型裂（24.70%），眶上畸形主要为Tessier 9和10型裂（38.27%）。组织受累范围无明确规律。STO分类法可作为Tessier分类法的补充，为颅面裂畸形的手术修复提供参考。
