crowning
The stage during delivery when the fetal head becomes visible at the vulval opening and does not recede between contractions.
Full Definition
Crowning marks a critical phase in the second stage of labor when the largest diameter of the fetal head passes through the vulval opening. At this point, the head remains visible even between contractions, indicating imminent delivery. This stage requires careful management to prevent precipitate delivery and minimize maternal trauma. Healthcare providers must be prepared for immediate delivery once crowning occurs.
