“…This finding is in agreement with medical studies [75][76][77], which addressed changes in nasal shapes and sizes in groups of 11-17 year old subjects in relation to gender discrimination. These studies have found that nasal height and nasal bridge length become fully mature at 15 years of age in males and 12 years of age in females.…”

The relationship between the shape and gender of a face, with particular application to automatic gender classification, has been the subject of significant research in recent years. Determining the gender of a face, especially when dealing with unseen examples, presents a major challenge. This is especially true for certain age groups, such as teenagers, due to their rapid development at this phase of life. This study proposes a new set of facial morphological descriptors, based on 3D geodesic path curvatures, and uses them for gender analysis. Their goal is to discern key facial areas related to gender, specifically suited to the task of gender classification. These new curvature-based features are extracted along the geodesic path between two biological landmarks located in key facial areas.Classification performance based on the new features is compared with that achieved using the Euclidean and geodesic distance measures traditionally used in gender analysis and classification. Five different experiments were conducted on a large teenage face database (4745 faces from the Avon Longitudinal Study of Parents and Children) to investigate and justify the use of the proposed curvature features. Our experiments show that the combination of the new features with geodesic distances provides a classification accuracy of 89%. They also show that nose-related traits provide the most discriminative facial feature for gender classification, with the most discriminative features lying along the 3D face profile curve.

“…17 The ala nasi in Asians is smaller than that in Indians or Caucasians. 17 Because the present study was performed using Japanese cadavers, the results may not be applicable to other races. Further studies are needed to elucidate whether our results can be applied to other races.…”

“…In African Americans, the PA varied from triangular to oval, showing differences in different population groups. [1] Anthropological studies suggest that climatic influence affects the width or breadth and height of the PA. [19][20][21][22][23] The PA directly affects the heating and humidity of the inspired air. In cold and dry climates, the heating and humidification of inhaled air is facilitated by a longer nasal passage and a narrower PA due to increased surface and longer period during which the air is inspired.…”

The pelvis and the skull bone are the best expressions of differences attributable to sex. In the skull, the shape of the piriform aperture (PA) is one of the classic indicators of morphological sexual dimorphism. PA shows racial and geographical differences due to variable climate. Racial differences in the shape and size of the nasal bones and PA have been reported, and these must be taken into account in neurosurgery, rhinology, and otolaryngology, and plastic and reconstructive facial surgery. It would help surgeons in surgical modifications of this area for the best suitable air passage modifications according to morphological and functional variations. Knowledge of these morphological variations can serve as a useful data set to delineate the anthropological characteristics of the population. As the skeletal structure of human face is influenced by environmental factors, specific standards of assessment must be drawn and applied to particular population under consideration. Thus, the present review gives a brief outline of the studies reported in literature that may be useful for anthropologist, forensic researchers, otorhinologist, and plastic surgeons.
