ABSTRACT

The apertura piriformis, which forms the bone entrance of the cavitas nasi, and the os nasales

and nasal cartilages, which form the upper borders of this entrance, constitute the nasal

skeleton. The morphometry of these structures, which form the back of the nose and the first

entrance of the respiratory tract, is important for respiratory function. Also, there's interest in

research on nose analysis, which includes both linear and angular nose measurements. The

aim of this study is to reveal the nasofrontal angle values and os nasale morphology measured

in male skulls.

41 male dry skulls registered in the inventory of Aydın Adnan Menderes University Faculty

of Medicine, Department of Anatomy were included in the study. After each skull included in

the study was photographed from lateral and frontal angles, the resulting images were

transferred to the ImageJ (version 1.54i) program and evaluated digitally. When the skulls

were examined from a lateral angle, the nasofrontal angle was measured. Morphological

examination of os nasales was done in 5 groups in accordance with the classification put

forward (done) by Hwang et al. in 2005, and through photographs taken from the frontal

angle.

When the skulls included in the study were examined, the smallest nasofrontal angle value

was found to be 101.16°. The largest nasofrontal angle value was 156.84°. The average

nasofrontal angle of 41 skulls was found to be 126.07°. When the skulls were evaluated

morphologically, 17 Type A, 3 Type B, 3 Type C, 3 Type D and 15 Type E os nasale were

found.

These data can serve as a database for male nasal morphology. This work will also aid

forensic investigations and anthropology.
