Rare craniofacial anomaly: Tessier no. 2 cleft

Four cases of facial cleft that fit the anatomic description of the rare Te ssier no. 2 cleft, with two patients having the no. 12 cleft extending to t he cranium as no. 2 clefts, are presented. In all patients, clinical expres sions of the anomaly were different. Thus, diverse surgical procedures were used in all cases. These cases and review of the literature help to define the soft-tissue and bony course of these clefts, and also emphasize the ro le of three-dimensional computed tomography scan imaging to show the bony c left route. The diagnosis and treatment plan of the no. 2 cleft as well as its cranial counterpart are discussed in this report.
