Pierre Robin Sequence Clinical Trial
Official title:
Usefulness of Cephalometry in the Second and Third Trimester of Pregnancy in the Diagnosis of Fetal Microretrognathia : Prenatal Cephal
Congenital retrognathia, with or without Pierre Robin Sequence (PRS), is a rare anomaly which
can be associated with chromosomal abnormalities. Respiratory and feeding consequences can be
present at birth. After birth, the diagnosis of retrognathia is based on the clinical
examination. Cephalometry can be used to complete the diagnosis. Several authors have
proposed the use of objective quantitative ultrasound parameters for the antenatal screening
of PRS. In our study, the investigators evaluated fetal cephalometry.
The aim First, the investigators studied the inter- and intra-observer reproducibility of
cephalometry. Second, the investigators established reference values for antenatal
cephalometry in normal fetuses. Third, the investigators compared the diagnostic performance
of cephalometry and the other angles described in the literature for the diagnosis of
retrognathia.
