More Than a Pretty Face: Nasal Morphology and Its Skeletal Signposts in Orthodontics

Abstract

Introduction: Facial aesthetics are increasingly central to orthodontic treatment planning, with the middle third—anchored by the nose—playing a pivotal role in profile harmony. Despite its anatomical and developmental significance, nasal morphology is often overlooked in conventional diagnostics.

Aims & objectives: This study investigates correlations between nasal parameters and skeletal patterns, vertical growth direction, using lateral cephalometric analysis. By highlighting the diagnostic potential of nasal morphology, this research aims to refine orthodontic assessment protocols and support more individualized, aesthetically focused treatment outcomes

Materials & methods: This cross-sectional radiographic study analysed nasal morphology in 90 subjects aged 15–27 using lateral cephalograms. Subjects were grouped by sagittal and vertical skeletal patterns and gender. Thirteen nasal parameters (linear and angular) were measured. Intra-examiner reliability was confirmed using ICC (>0.9).

Results: Emerging evidence suggests nasal features serve as non-invasive indicators of underlying skeletal discrepancies.

Conclusion: The comprehensive analysis of nasal measurements reveals significant variations influenced by skeletal class, growth pattern, and gender
