Dimensions of the anterior nasal bony aperture in a sample of Syrian patients Cone-beam computed tomography study
Abstract
Introduction: The anterior nasal bony aperture (Apertura piriformis) plays an important role in overall facial symmetry and harmony. Its shape, size and orientation affect facial aesthetics and can influence the success of orthodontic treatments. Understanding the relationship between the anterior nasal aperture and its impact on aesthetics and treatment is essential to optimize treatment outcomes. This study aimed to assess some morphological characteristics of the anterior nasal aperture and the ratio between them and their differences between males and females in a sample of Syrian patients. Materials and Methods: The sample consisted of 100 cone beam computed tomography scans that were retrospectively analyzed to measure the horizontal diameter NH and vertical diameter NV of the anterior nasal bony aperture, and descriptive statistics were calculated in males and females and differences were investigated using T-Test analysis for independent samples. Results: T-Test indicated a statistically significant difference between the two groups and males showed larger mean NH and NV compared to females indicating a wider and longer anterior nasal aperture in males. The ratio of horizontal to vertical diameter showed no statistically differences between males and females. Conclusion: The results of the current study provide valuable measurements and information for clinical practitioners in orthodontics and related fields. These measurements can contribute to a better understanding of the natural variation in anterior nasal dimensions and overall facial harmony, and can be used as a reference for future research and clinical applications.
