Nasal bone hypoplasia in trisomy 21 at 15-22 weeks' gestation.
OBJECTIVE To investigate the potential value of ultrasound examination of the fetal profile for present/hypoplastic fetal nasal bone at 15-22 weeks' gestation as a marker for trisomy 21. METHODS This was an observational ultrasound study in 1046 singleton pregnancies undergoing amniocentesis for fetal karyotyping at 15-22 (median, 17) weeks' gestation. Immediately before amniocentesis the fet...

متن کاملNuchal translucency and nasal bone for trisomy 21 screening: single center experience.
AIM To evaluate the feasibility and diagnostic accuracy of fetal nuchal translucency and nasal bone assessment at 11-14 weeks for screening of trisomy 21 at a single center. METHODS Nuchal translucency measurement and nasal bone evaluation in relation to the fetal karyotype for singleton fetuses were retrospectively assessed at the Ospedale Microcitemico, Cagliari, Italy, in a three-year peri...
متن کاملUse of Forehead Flap for Nasal Tip Reconstruction after Traumatic Nasal Amputation
Nose is one of the most important aesthetic unit of the face.Management of nasal trauma plays a significant role in the practices of the majority of facial and reconstructive surgeons.

Here we present an illustrative case report of the traumatic amputation of a nasal...
متن کاملLikelihood ratio for trisomy 21 in fetuses with absent nasal bone at the 11-14-week scan.
OBJECTIVE To update the likelihood ratio for trisomy 21 in fetuses with absent nasal bone at the 11-14-week scan. METHODS Ultrasound examination of the fetal profile was carried out and the presence or absence of the nasal bone was noted immediately before karyotyping in 5918 fetuses at 11 to 13+6 weeks. Logistic regression analysis was used to examine the effect of maternal ethnic origin and...
