이차 구순열비변형의 비성형술시 비주 지지대 확보를 위한 allogenic dermis 사용

Abstract

Rhinoplasty of cleft lip patients is often unsatisfactory because of problems resulting from cartilage weakness and shortness of the columella. The columella must have a balanced position in relation to the adjacent alar rim and edial crura. Construction of the columella by cartilaginous strut can provide structural support for the lower lateral cartilage. The columellar strut is a popular and effective form of graft. For most surgeons, an autogenous artilage graft is the first choice in rhinoplasty because of its resistance to infection and resorption. On the other hand, an allogenic dermal graft not only has the advantage of averting donor site morbidity but also are resistant to infection, resembling autogenous cartilage grafts. In this article, we report 2 cases of rhinoplasty using allogenic dermis(MegadermTM) in secondary cleft lip nasal deformity patients.
