Antenatal Ultrasound Fetal Pinna Measurement and Evolving Nomogram in South Indian Population in Normal Pregnancies
Introduction: The abnormality of pinna length and morphology can indicate chromosomal anomaly and can be a marker for chromosomal aneuploidy. There are many studies about sonographic pinna length measurements correlating this with gestational age and fetal biometric measurements. Studies have b...

| description | Introduction: The abnormality of pinna length and
morphology can indicate chromosomal anomaly and can
be a marker for chromosomal aneuploidy. There are many
studies about sonographic pinna length measurements
correlating this with gestational age and fetal biometric
measurements. Studies have been done in different
population about the ultrasound pinna measurement with
deduction of nomogram. To our knowledge this study has
not been done on the South Indian population.
Aim: To evolve nomogram for fetal pinna length
measurement for South Indian population and to correlate
this with gestational age and fetal biometry.
Materials and Methods: Pinna length measurements
(from the tip of the helix to the tip of the lobe) are measured
prospectively in normal singleton pregnancies between 16-
28 weeks. Normal pregnancy is normal sonographic study
and/or normal infant examination after birth. The ear length
is measured in either oblique sagittal or coronal plane in
millimeters and this is correlated with the gestational age
and fetal biometry.
Results: There is a linear relationship between the pinna
length and the various fetal biometric parameters and the
gestational age of the fetus.
Conclusion: Study deduces the nomogram of the fetal
pinna length. A linear relationship between the pinna
length and the gestational age was established and there
is no significant difference of pinna length as compared to
the studies done on the other populations. |
