Purpose: The purpose of this study is to evaluate patients with nasal septum deviation through the horizontal dento-cellular measurement-rhin postero-anterior radiographs. The material of the study consists of 25 patients (15 girls and 10 men) with nasal septum deviation and 25 (12 girls and 13 men) with non-nasal septum deviation control group, including 50 orthodontic patients (27 girls and 23 men; average age: 15,05 ± 1,72 years). Scale and dental horizontal direction measurements are calculated using postero-anterior sefalometric radiographs. The differences between groups were analyzed by an independent sampling t test. The findings: in the group with nasal septum deviation, the la-teroorbital width, the maxilar width, the nasal width and the upper molar width, the nasal septum deviation-free control group was identified as sta-thicker (P<0.05). The result is that patients with nasal septum deviation, compared to the control group, have scalable and dental anomalies.

Material and Methods: This study consisted of 50 orthodontic patients (27 female and 23 male; average age=15.05±1.72 years) divided into two groups according to the nasal septum deviations presence: nasal septum deviation group (25 patients: 15 female and 10 male) and without nasal septum deviation control group (25 patients: 12 female and 13 male). Transversal skeletal and dental measurements were calculated on postero-anterior cephalometric radiographs. Group differences were analyzed using independent samples t test. Results: The lateroorbitale width, maxillare width, nasal width and upper intermolar width were statistically significantly narrower in group in the nasal septum deviation group than in the without nasal septum deviation control group (P<0.05). Conclusions: Nasal septum deviation patients show skeletal and dental anomalies in comparison to controls.   Keywords: nasal septum deviation, cephalometric, anterior cephalometric radiograph.
