Analysis of Nasal Morphology in Skeletal Class I and Skeletal Class II Malocclusion: An Observational Study

Abstract

Background and objectives The nose is one of the major focuses of face attractiveness. Through careful evaluation of the soft tissue drape, a treatment plan can be designed to enhance a patient's facial attractiveness. The aim of this study was to evaluate and assess the variations in nasal morphology among class I malocclusion and class II horizontal and class II vertical malocclusion. Material and method Lateral cephalograms of 27 patients were taken and consisted of three groups: skeletal class I malocclusion, class II horizontal malocclusion, and class II vertical malocclusion. The various linear and angular measurements specific to nose were assessed. Results and conclusion In class II and class I malocclusion, the nose is observed to be straight and convex, respectively. Additionally, compared to class II horizontal malocclusion, it is more convex in class II vertical malocclusion. Vertical growers or high-angle cases are more likely to have a nose with an increased inclination toward nasal dorsum convexity than horizontal growers or low-angle instances.
