An anterior lip in labor refers to a condition where a portion of the cervix on one side of the babys head (usually the anterior or front of the cervix) is still present when a person is almost fully dilated. It is a normal part of the birth process, and almost every woman will have an anterior lip at some point in labor because it is the last part of the cervix to be pulled up over the babys head. An anterior lip can slow down the womans progress from the first stage of labor to the second stage, but it does not require management and is best left undetected. Waiting to push can give the lip time to move out of the way and make pushing more effective. Sometimes, a cervical lip is caused by the babys position in relation to the pelvis. For this reason, if a cervical lip is present and causing issues, it can help to try position changes to help the baby get into a better position and clear the cervical lip.
