Facial cleft detected: is the palate normal?

Area of Science:

• Medical Imaging
• Prenatal Diagnosis
• Craniofacial Anomalies

Background:

• Current mid-trimester ultrasound scans have limited sensitivity for detecting facial clefts.
• Accurate assessment of fetal palate involvement is critical for surgical planning and long-term care.
• Inconsistent terminology and diagnostic challenges hinder antenatal identification of clefts, especially midline palatal defects.

Purpose of the Study:

• To highlight the limitations in current prenatal ultrasound detection of facial clefts.
• To emphasize the importance of accurately identifying fetal palate involvement.
• To discuss nomenclature issues and imaging methodologies for fetal palate assessment.

Main Methods:

• Review of current ultrasound screening protocols for facial clefts.
• Discussion of diagnostic challenges in identifying palate involvement.
• Description of 2D and 3D ultrasound techniques for fetal palate imaging.

Main Results:

• A three-point ultrasound screening protocol can improve detection sensitivity for facial clefts.
• Accurate antenatal identification of palate involvement is often missed, particularly midline clefts.
• Standardization of nomenclature and advanced imaging techniques are needed.

Conclusions:

• Enhanced ultrasound protocols are necessary for improved prenatal detection of facial clefts and palate involvement.
• Clearer nomenclature and advanced imaging techniques are essential for accurate antenatal diagnosis and management planning.
• Early and accurate diagnosis impacts surgical, audiology, and orthodontic care pathways.
