[Analysis of the nasal area in unilateral cleft lip and palate, by means of cephalometric teleradiography].

In a cross-sectional study with 149 patients with complete unilateral cleft lip and palate and 157 non-cleft patients aged from twelve to sixteen, Caucasian males and females were evaluated through lateral cephalometric radiographs of the nasal area. One angular (SNA), 4 linear (S-N; N-P'; P'-Ptm'; Ptm'S) and medial cephalometric measurements of the nasal area were used. In a comparative analysis of the nasal area in cleft lip and palate and control groups one can conclude that: 1. The nasal area in cleft patients is smaller than in non-cleft patients. 2. There is no correlation between the angle (SNA) and the nasal area for the cleft patients and control patients.
