비주 결손의 범위에 따른 피판의 선택과 재건

Abstract

Congenital and acquired columella defect is rare. Columella is a small subunit of the nose, but determines the projection of nasal tip, defines the nasolabial angle, and is related to the structural relationship between alar rims and the nasal base. The showing of columella from various angles is also important for aesthetic point of view. Thus, reconstruction of columella defect is quite challengeable operation for surgeons. The recipient site should be harmonious with surrounding area, also the donor site should maintain the normal anatomy without secondary deformity. In this paper, we report two cases of reconstruction of columella defect in Vietnamese children with different techniques.
