Lateral Cephalometric Analysis of the Nasal Morphology in a Group of Yemeni Adults

Abstract

This cross-sectional study was conducted to determine normative cephalometric values for nasal morphology and its relationship to craniofacial structures in Yemeni adults. The study also evaluated gender differences and compared Yemeni nasal parameters with Saudi norms, The sample included 100 Yemeni dental students (50 males and 50 females) aged between 18 and 25 years, selected from the University of Science and Technology in Sana’a, Yemen. All participants had skeletal Class I relationships and were selected according to specific inclusion criteria. Lateral cephalometric radiographs were obtained and analyzed digitally using EZOrtho software Version:1.3. Linear and angular measurements related to nasal size, shape, and facial prominence were assessed. The results revealed significant gender differences (P<0.05) with males showing greater nasal length, depth, and anterior projection, while females had wider nasolabial and nasofrontal angles. Compared with the Saudi population, Yemeni adults were found to have longer and more projected noses, as well as greater maxillary and mandibular prominence. The result demonstrated distinct nasal morphological characteristics in Yemeni adults. For establishing population-specific cephalometric norms. These standards can be useful for accurate orthodontic diagnosis, treatment planning, and facial esthetic evaluation, helping to achieve results that are suitable both functionally and culturally for Yemeni patients.
