Face presentation
Fetal malpresentation where the face is the presenting part with complete head extension.
Full Definition
An uncommon fetal presentation occurring in approximately 1 in 500-600 deliveries, where the fetal head is completely extended with the face presenting first. The mentum (chin) serves as the reference point for position determination. Vaginal delivery may be possible if the chin rotates anteriorly, but posterior chin positions typically require cesarean delivery due to obstructed labor risk.
Usage
Usage note: Mentum position (anterior vs posterior) is crucial for delivery method determination.
