[Anatomy of the cartilages of the nose with secondary deformity associated with unilateral cleft lip].

To explore the influence of displacement and hypoplasia of nasal cartilages to cleft lip nose, 38 patients with secondary cleft lip nasal deformity were randomly chosen. Measurement of length and width of the nasal cartilages was made, and places of them were inspected. The displacement of the cartilages was found in each nose, and hypoplasia of cartilages was in those noses whose deformities were more severe. The conclusion is that both displacement and hypoplasia of nasal cartilages are causing factors of nasal deformity.
