“…Yuzbaşıoglu et al [20] determined the PA length:PA width ratio was 1.36 ± 0.17 cm in males, and 1.30 ± ± 0.17 cm in females. Yuzbaşıoglu et al [20] conducted a study and determined the age range as very wide. Although they did not divide the groups further to age subgroups, the rate of PA height to PA width and the averages of PA height and width were found to be similar with our study.…”

“…The morphometric evaluation of 3D CT technique is useful for obtaining reliable and objective data in anatomical studies [10,18]. Yuzbaşıoglu et al [20] measured the PA length and width, and determined the PA length, PA width ratio; and evaluated the PA types of 120 subjects (58.23 ± 16.24 age/ /years) by using 3D CT images. In this study, there was a significant difference between gender groups in terms of PA length and width.…”

“…PA is bordered by the nasal bones, the frontal processes of the maxillary bones and the anterior nasal spine [17]. This skeletal aperture is the anterior limit of the skeletal nose and includes the main factors to create the actual shape, size and form of the nose [13,20]. The number of studies on PA is limited.…”

Background: The purpose of study was to evaluate normal morphometric measurements of piriform aperture (PA) by limiting the age range in genders to show the morphometry of the relevant and close proximal cranial structures; and also to investigate whether these are in compliance with the golden ratio. Materials and methods: Our study was performed on 83 (42 female, 41 male) multidetector computed tomography images obtained from patients. A total of 14 morphological measurements were performed including the height of PA, the width of PA and 12 cranial structures; and these measurements were evaluated for compliance with the golden ratio. The differences of 14 parameters between the genders and age groups, and also the interaction of these two factors were analysed. Results: In our morphometric study, significant difference between the genders was found in all measurements except for the distance between vertex and rhinion (V~Rh), between rhinion and right foramen supraorbitalis (Rh~FSO R), between rhinion and left FSO (Rh~FSO L), and the width of PA on the level between the right and left foramen infraorbitalis (PAW~FIO) with the difference valid for both age subgroups (p < 0.05). When the differences between the age subgroups were evaluated, there was significant difference only at the widest distance of cranium (CW; p = 0.008); and it was observed that the average has increased with age in both genders. When the golden ratio was examined, the ratio of the distance between anterior nasal spine and nasion to the height of piriform aperture (NSA~N:PAH) was found to be within the limits of the golden ratio in males (p = 0.074). No golden ratio has been found in females. Conclusions: In our study, significant differences were detected between genders in all parameters of PA and in some parameters of the close cranial structures in the age group we examined. The effect of age was detected only in the CW parameter, and the PA and close cranial structures were not affected. In our study, the averages of the morphometric measurements of 13 parameters of young adults were determined. The PA and surrounding cranial structures are important for the area and related surgical procedures; however, gender differences must be considered in this respect. In addition to this, in the PA, which is the anterior limit of the skeletal nose in males, the NSA~N:PAH ratio having the ideal golden ratio limits is valuable in aesthetical terms and due to its position of the PA in the face.

“…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.
