Craniofacial anthropometric investigation of relationships between the nose and nasal aperture using 3D computed tomography of Korean subjects

Abstract

This study investigated the relationships of morphology and locations of the nose and nasal aperture by using major craniofacial landmarks on the human skull and face for craniofacial reconstruction/approximation of Koreans. In the frontal view, the positions of bony landmarks on the skull, including the nasal aperture, were correlated with the positions of nasal landmarks vertical to the transverse plane. In profile, the positions of bony landmarks on the skull were correlated with the positions of nasal landmarks horizontal to the coronal plane. Overall, 26 of the 76 measurements demonstrated significant correlations between the corresponding landmarks on the nose and nasal aperture. Simple regression equations were produced from the results. This study showed that the nose and nasal aperture are significantly related to each other in terms of their morphology and location in Koreans. The prediction guidelines, produced as regression formulas, can be applied to craniofacial reconstruction/approximation and bio-anthropological research of Korean skulls. The study results can also be used clinically in rhinoplasty and nasal reconstruction surgery.

Exploring Craniofacial Anthropometry in the Ethnic Adult Population of Meghalaya, Northeast India: A Cross-Sectional Study

“…[8,23] Few authors have studied the role of computed tomography scans, magnetic resonance scans and digital photography in craniofacial anthropometry. [5,24,25] The inherent risk of exposure to radiation, cost and availability are limitations to such types of anthropometry.…”

Developing an eyeball positioning method in the eye orbit for craniofacial identification in Korean population

“…To this end, we incorporated facial landmarks and reference planes produced in the uniform mechanism with previous studies of correlations between eyebrows/orbits and the nose/nasal aperture groove. 12,13 This allowed us to reconstruct/approximate facial features based on the morphology of the unidenti ed skull as well as to minimize interference caused by estimations based on the features of different cultures. We are currently investigating the relevant features of the mouth and ears; once these studies are completed, an estimation method for the entire facial feature morphology of the Korean skull will be developed and tested for craniofacial reconstruction/approximation.…”

“…To this end, we built on facial landmarks and reference planes produced in the uniform mechanism with the previous studies of correlations between eyebrows/orbits 12 and nose/nasal aperture groove. 13 Regression equations were developed to estimate eye position and protrusion in the eye orbit; these data were combined with other anatomical features around the eyes to reconstruct Korean features. The appropriate proportions of, and distances among, facial features were estimated to improve the correlations among features.…”

“…Position of the nasal alae were predicted by the distances between coronal plane and nasal aperture grooves for each side view and between orbitale planes and nasal aperture grooves and midsagittal plane and alares for front view (Fig. 4) [11].…”
