Abstract (2. Language): 
Objective: Nasal bone length of fetuses (NBL) in second trimester by measuring during routine obstetric sonography examination to determine the range of normal value for Turk society. Material-Method: A total of 16-22 week gestational aged 250 healthy fetuses nasal bone lenght was measured with transabdominal ultrasonography. Fetuses was evaluted by using transabdominal look with Toshiba Xario USTS-770 device and 3,5 mHz convex transducer. Routine second trimester obstetric examination of the fetuses were done and NBL of fetuses which sonographcally detected healty were measured. Results: Measurement of NBL of 16, 17, 18, 19, 20, 21 and 22 week gestational fetuses were calculated respectively as: 2.9– 4.6 mm, 3.3–5.1 mm, 3.4–7.3 mm, 4.3–6.6 mm, 4.8–7.3 mm, 4.6–7.5 mm, 5.6–7.2 mm (average of 5.4 mm ± 0.87). Conclusion: Nasal bone lenght of 16-22 week gestational aged fetuses were calculated as 2.9-7.5 mm. It should be considered as normal in this range. Nasal bone lenght of second trimester fetuses under 2.9 mm should be evaluated for fetal anomalies.

Abstract (Original Language): 
Amaç: İkinci trimesterdeki fetüslerin nazal kemik uzunluklarını (NKU) rutin obstetrik sonografi incelemesi sırasında ölçerek Türk toplumu için normal değer aralığını belirlemek. Materyal-Metot: Çalışmaya 16–22 gebelik haftalarında 250 gebeye ait 250 sağlıklı fetus dahil edildi. Fetüsler Toshiba Xario USTS-770A cihazı ile 3.5 MHz konveks transduser kullanılarak transabdominal bakı ile değerlendirildi. Fetüslerın rutin ikinci trimester obstetrik incelemesi yapıldı ve sonografik olarak sağlıklı olduğu tespit edilen fetusların NKU’ları ölçüldü. Bulgular: 16, 17, 18, 19, 20, 21 ve 22.’inci gestasyonel haftalardaki fetusların NKU ölçümleri sırasıyla hesaplandı: 2.9–4.6 mm, 3.3–5.1 mm, 3.4–7.3 mm, 4.3–6.6 mm, 4.8–7.3 mm, 4.6–7.5 mm, 5.6–7.2 mm (ortalama 5.4 mm ± 0.87). Sonuç: Çalışmamızın sonucunda 16–22 gebelik haftalarında normal fetal NKU ölçümünü 2.9 ile 7.5 mm arası olarak hesaplandı. Bu nedenle 16-22 gebelik haftalarında NKU için 2.9 mm’nin altındaki değerler fetal anomali açısından araştırılmalıdır.
