Morphometric features of the piriform aperture and nasal bones [Apertura piriformis ve os nasale'nin morfometrik özellikleri]

The piriform aperture which is the bony entry of the nasal cavity, the nasal bones and cartilages make the nose structure. The morphometry of these structures making the dorsal part of the nose and the entry paint of the respiratory tract are functionally important for the respiratory system. In this study, the piriform aperture and nasal bones are investigated in 38 craniums. The inner border of the nasal bones were measured 21.02±3.5 mm in length, outer border 24.00±3.53 mm, upper border 8±1.94 mm, bilateral 12.25±2.55 mm, width of the lower border 10.29±1.67 mm, bilateral 14.26±1.86 mm. The piriform aperture height was 35.95±3.14 mm and width at the widest point in the lower margin 23.99±2.62 mm, and width at the upper margin 15.37±1.97 mm. The most common types of the nasal bones were Type 1 (%57.9) and Type 4 (%15.8). The findings of this study were discussed with former studies.
