“…The width (PA-W) was wider than the Turks (Table IV) (Yüzbasioglu et al,), Korean, Caucasian, German, Austrian, Anatolian and American results, and smaller than in black people (Table IV) (Lang & Baumeister, 1982, obtained from the study by Hwang et al;Hoffman et al, 1991;Ofidile, 1994;Hommerich & Riegel, 2002;Karadag et al, 2011).…”

SUMMARY:The piriform aperture is an anatomical structure generally pear-shaped, formed by some facial bones. The knowledge of its morphological presentation is of significant importance for performing a surgical procedure. This study aimed to analyze the morphometry and shape of the piriform aperture in human skulls, considering the sexual dimorphism of this structure. One hundred (100) human skulls were evaluated. The measurements were made with a digital caliper rule. Two parameters were analyzed: the height of the piriform aperture (R-ANS) -distance between the bottom edge of internasal suture to the anterior nasal spine; width (PA-W) -the longest distance in a transverse plane. Its form was evaluated according to seven types described in the literature and the sex differentiation (based on the Vanrell frame). For data analysis between sexes, we used the Student's t-test (p<0.05; CI: 95 %). In this study it was observed that the height (R-ANS) of the piriform aperture in males (31.4 mm) was higher than in females (29.4 mm), without significant differences. The width (PA-W) had equal means values for both sexes (25.7 mm). Regarding the shape of the pyriform aperture, it was found that the type I (pear) is the most common in males (43.6 %) and in women the type VII (rounded) is the predominant type (36 %). When sexes were evaluated in a combined manner, it was observed that the most common was the type I (pear -39.1 %) and the less common were type III (diamond -0.0 %), type II (inverted heart -1.6 %) and type IV (inverted heart -3.1 %). Knowledge of these morphometric data and piriform aperture formats is essential for surgical procedures involving this anatomical region. The results, particularly those related to the shape of the piriform aperture in women, may contribute to future work related to this facial structure, leading to better surgical decisions.

“…So, excess soft tissue changes needs wider and circular PA. With respect to shape of the piriform aperture, in Boyan study type II was predominant (51.8%), followed by type I (25.0%) and then types IV and III with similar frequency (12.5% and 10.7%, respectively) [3]. According to Ofodile, the shape of the piriform aperture was oval (equivalent to types III and IV) in Ashanti, triangular (type II) in Austrians and American Indians, and varied from oval to triangular in black Americans (type III) [10]. It was observed that the most common was the type I (pear -39.1 %) and the less common were type III (diamond -0.0 %), type II (inverted heart -1.6 %) and type IV (inverted heart -3.1 %) [15].…”

Background: Nasal bone and piriform aperture shows racial and geographical differences because of variable climate. Aim: the aim of this study was to evaluate the dimensions (maximal width and length), the size and the shape of the piriform aperture (PA) and nasal bone in South Indian adult. Materials and Methods: In this observational study, dimension of piriform aperture and nasal bone were measured using digital Vernier Calipers after assessing landmarks around the piriform aperture on the norma frontalis in Frankfurt plane in 51 skull of South Indian origin. Results: The mean height of the piriform aperture between male and female showed significance this has correlated well with the previously data acquired from human skulls. The present study findings were similar to most of Indian skulls having platyrhine type of piriform aperture (triangular to oval shape with piriform aperture index of 0.79. The Mean length and width of nasal bone did not show sexual dimorphism. Conclusion: the analysis of size and shape of the piriform aperture showed the existence of a significant sexual dimorphism. These results encourage us to go further with functional and imaging correlations. This study will also be helpful in forensic research, anthropology and plastic surgery.

“…The lateral border articulates to the frontal process of the maxilla. [3,[7][8][9] Inferiorly, the PA is the large opening in the nasal region and the anterior opening of the nasal cavity. It is bounded superiorly by the nasal bones and laterally and inferiorly by each maxilla.…”

“…This morphological variability is necessary to understand the geographic and ethnic differences and can be analyzed by radiography in forensic context. [2,5,7] In addition to forensic implications, the knowledge of the PA and nasal bone variations is fundamentally significant in anthropology and otolaryngology. [2] The present review gives a brief outline of the forensic value of PA.…”

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.
