Abstract
Background: Factors affecting the appearance of the nose and the size of the nasal angles are different. The aim of this study was to examine the influence of the vertical developmental pattern on the nose appearance. Material and methods: Lateral cephalogram from 144 adult Caucasian subjects from the central Balkan were analyzed (72 male and 72 female), with orthognathic jaw relationship – class I and different types of divergence pattern. The profile type of nose, the shape of the nasal dorsum and the value of the nasal angles (nasofrontal, nasofacial, nasolabial and nasal tip angle) were determined for each person. Subjects were divided into three groups based on the values of ANB angle (sagital relation between the maxilla and mandible), Wit’s appraisal, SN/GoGn (the angle of mandibular divergence pattern). These groups are subjects with hypodivergent, normaldivergent and hyperdivergent growth pattern. Statistical analysis included differences separately for each gender between different types of divergence. Results: The results indicated that some nasal forms are more common in certain types of divergence, but that these differences did not show statistical significance, in contrast to the results of authors from other areas. Conclusions: The clinical implication of current study relates to the fact that nasal reconstruction should not be based on the type of divergence, but on other factors.
