Objective The objective of this case report is to evaluate the faculty of a recently described original three-dimensional ultrasound technique to detect pathological processes of the fetal palate. Method The palate of the fetus of a patient with a personal history of isolated incomplete cleft palate is evaluated by three-dimensional ultrasound at 34 weeks of gestation. The postnatal Wndings are compared to the prenatal investigation. Result The used three-dimensional ultrasound technique provides selective visualization of the total hard palate which permits the prenatal diagnosis and multidisciplinary approach of an incomplete cleft palate. Conclusion These prenatal Wndings might encourage further studies to conWrm the value of this recently described innovative technique in the diagnosis and surgical prenatal counselling of fetal cleft palate.

K E Y W O R D S: cleft lip and palate; diagnostic test; prenatal diagnosis; three-dimensional ultrasound ABSTRACT Objective To investigate the accuracy of prenatal axial three-dimensional (3D) ultrasound in predicting the absence or presence of cleft palate in the presence of cleft lip. were 81 cases with a prenatal two-dimensional (2D) ultrasound screening diagnosis of unilateral or bilateral cleft lip at 22-25 weeks of gestation referred to our tertiary care center. Of these, 79 fetuses were included in this prospective study and two were excluded. Axial 3D ultrasound imaging of the fetal palate was performed and the diagnoses were compared with clinical findings at delivery. The frequencies of intact and cleft palate, the degree of association between the prenatal predictions and postnatal findings and the probability of detection of cleft lip and palate were determined.

The aim of this research was to evaluate the ability of three-dimensional (3D) ultrasound for demonstrating the palate of fetuses at high risk for cleft palate. Method Fifty-seven fetuses at high risk for cleft palate were referred for specialist ultrasound at 12-40 weeks' gestation. A detailed assessment of palate was made using both two-dimensional and 3D ultrasounds on the axial plane. Antenatal diagnoses were compared with postnatal findings. Results Cleft palate was suspected in 13 (22.8%); a normal palate was demonstrated in 38 (67%), and in six (10.2%), the palate view could not be obtained. Mean gestational age at the first visit was 27 weeks 6 days (range of 12-40 weeks 3 days). Examination after delivery revealed that one of the 38 fetuses with presumed normal palate had a cleft hard palate, and one had a cleft soft palate (false negative 5%). Among the 13 fetuses with suspected cleft palate, three had an intact palate (false-positive 23%). Sensitivity, specificity, positive predictive value, and negative predictive value of detection of palatal clefts were 71.4%, 91.9%, 62.5%, and 94.4%, respectively. Conclusion Using 3D technology, we diagnosed a cleft palate in 83% of high-risk cases, with 5% false negative. 3D technology might produce some technical artifacts resulting in a 23% false-positive rate.

Objectives To systematically review the diagnostic accuracy of second-trimester transabdominal ultrasound in detecting orofacial clefts in low-and high-risk populations and to compare two-dimensional (2D) with three-dimensional (3D) ultrasound techniques. Methods MEDLINE and EMBASE were searched for articles published in English, Dutch, French or German using the keywords 'cleft' and 'ultrasound' or 'screening' or 'sonogram' and 'prenatal' or 'antenatal' or 'fetus' to identify cohort studies and randomized trials in order to assess the detection rate by prenatal ultrasound of cleft lip and palate in high-risk and low-risk pregnant women. Results Of 451 citations identified, 27 met the criteria for the systematic review, 21 involving unselected lowrisk populations and six involving high-risk populations. In the selected studies there was diversity in the gestational age at which the ultrasound examination was performed and there was considerable variety in the diagnostic accuracy of 2D ultrasound in the low-risk women, with prenatal detection rates ranging from 9% to 100% for cleft lip with or without cleft palate, 0% to 22% for cleft palate only and 0% to 73% for all types of cleft. 3D ultrasound in high-risk women resulted in a detection rate of 100% for cleft lip, 86% to 90% for cleft lip with palate and 0% to 89% for cleft palate only. Conclusions 2D ultrasound screening for cleft lip and palate in a low-risk population has a relatively low detection rate but is associated with few false-positive results. 3D ultrasound can achieve a reliable diagnosis, but not of cleft palate only.
Analysis of Fetal Palate to Assist Pre-natal Ultrasound
JOURNAL OF CLINICAL AND DIAGNOSTIC RESEARCH, 2016
Introduction: Cleft palate is one of the major facial congenital malformation in newborns. Pre-natal detection of this malformation is limited to detection of clefting of hard palate but isolated soft palate clefting still remains challenge for sonologists. As Indian literature is limited present study was attempted to provide dimensions and position of fetal palate by digitized images. Aim: To study dimensions, position and differences in parameters between second and third trimester fetuses.
Analysis of fetal palate as a tool in prenatal ultrasound examination
Romanian Journal of Stomatology
Prenatal ultrasound examination should take place between 18 and 20 week of gestation and is important for early detection of fetal anomalies such as the facial malformations. One important anatomic element is the palate that raises echographic technical difficulties such as the shadowing by facial bones and, especially, by the superior alveolar ridge, the fetal prone position and its localization, respectively, profoundly, inside of fetal head or anatomic obstacles such as the fetal tongue, so new echographic examination techniques are being under evaluation. The prenatal detection rate of fetal cleft palate remains low, so various methods of examination are being proposed. The ultrasound assessment of the fetal face is made by 2D ultrasound, technique completed by 3D ultrasound, which includes the evaluation in both axial and coronal planes, with the uvula being analyzed in two types of section, transversal and sagittal. In the latter to epiglottis is a landmark that confirms the ...
