Normal range fetal nasal bone length chart
WebIn the recent years, sonographic images of fetal nose have gained popularity in detecting trisomy 21 and other aneuploidies. Reference values for nasal bone length have been reported in different countries and ethnic populations. However, there was no reference range for the fetal nasal bone length (NBL) in the Filipino population. This prospective, … Webmean length ranging between 1.69 mm and 2.94 mm. Nasal bone length demonstrated to be strongly correlated with all of the fetal anthropometric parameters (p < 0.001) and with the gestational age (R² = 0.59). CONCLUSION: Despite the preliminary character of the present study, a reference range of fetal nasal bone length was established.
