Tessier No.5 Cleft 환자에서의 악교정 수술 시 고려사항: 증례보고

Consideration for Orthognathic Surgery on Tessier No.5 Cleft Patient – A Case Report

Facial clefts are the common craniofacial malformations, often involves palate and lips. However, it rarely occurs obliquely in the soft and hard tissues of the face, which isestimated to occur 0.24% of facial clefts. It was Tessier who postulated the anatomy‑basedclassification system for craniofacial clefts - the sagittal plane and orbit. This case reportis about a patient with Tessier no.5 cleft, which is rare among them and extends from theorbit to the maxilla. There is not much literature on the orthognathic surgery of Tessiercleft patients. Orthognahtic surgery of cleft patients are difficult and complicated becauseof problems such as recurrence, healing delay, tooth loss, soft tissue and bone necrosis,and infection due to previous procedures. Since cleft patients' maxillary surgery has afundamental tendency to recur, and most of them are not completely horizontally stable andhave movements after Le Fort I osteotomy, it is recommended to have a more sufficientperiod of intermaxillary fixation than in conventional surgery. In the case of cleft patients,it is also necessary to consider this during maxillary surgery because of thin upper lip thesmall forward movement effect. This case report aims to investigate the effectiveness andlimitations of orthognathic surgery for Tessier cleft patients.
