[Fetal dysmorphology: a practical approach in utero].

Area of Science:

• Medical Genetics
• Developmental Biology
• Pediatrics

Background:

• Dysmorphology studies congenital malformations and anatomic variations.
• Over 2500 dysmorphic syndromes are known, often associated with intellectual disability.
• Craniofacial and limb anomalies are key diagnostic indicators in dysmorphology.

Purpose of the Study:

• To highlight the role of fetal imaging, specifically 3D ultrasound, in analyzing facial dysmorphology.
• To emphasize the importance of combining fetal ultrasound expertise with pediatric dysmorphology knowledge for accurate diagnosis.
• To outline the diagnostic and prognostic implications of identifying fetal facial anomalies.

Main Methods:

• Detailed analysis of fetal facial structures using advanced 3D ultrasound techniques.
• Integration of clinical expertise from fetal ultrasound practitioners and pediatric dysmorphologists.
• Consideration of pregnancy context and family history in facial anomaly assessment.

Main Results:

• 3D ultrasound enables precise examination of fetal facial features.
• Identification of facial anomalies can indicate severe fetal syndromes or diseases.
• Facial analysis aids in ruling out syndromes with poor prognosis when other malformations are present.

Conclusions:

• Prenatal diagnosis of dysmorphic syndromes is enhanced by advanced imaging and expert collaboration.
• Accurate facial analysis is crucial for determining the prognosis and management of fetal anomalies.
• Ethical considerations regarding parental disclosure of potential dysmorphism are paramount until a definitive diagnosis is established.
