Background: Abnormal fetal ear length is a feature of chromosomal
disorders. Fetal ear length measurement is a simple measurement that
can be obtained during ultrasonographic examinations.
Aims: To develop a nomogram for fetal ear length measurements in our
population and investigate the correlation between fetal ear length, gestational
age, and other standard fetal biometric measurements.
Study Design: Cohort study.
Methods: Ear lengths of the fetuses were measured in normal singleton
pregnancies. The relationship between gestational age and fetal ear
length in millimetres was analysed by simple linear regression. In addition,
the correlation of fetal ear length measurements with biparietal
diameter, head circumference, abdominal circumference, and femur
length were evaluated.Ear length measurements were obtained from
fetuses in 389 normal singleton pregnancies ranging between 16 and
28 weeks of gestation.Results: A nomogram was developed by linear regression analysis of
the parameters ear length and gestational age. Fetal ear length (mm)
= y = (1.348 X gestational age)-12.265), where gestational ages is in
weeks. A high correlation was found between fetal ear length and gestational
age, and a significant correlation was also found between fetal
ear length and the biparietal diameter (r=0.962; p<0.001). Similar correlations
were found between fetal ear length and head circumference,
and fetal ear length and femur length.
Conclusion: The results of this study provide a nomogram for fetal
ear length. The study also demonstrates the relationship between ear
length and other biometric measurements
