Why does a bilateral cleft lip happen?

Most clefts are due to random chance in the first couple months after conception.

Normally there is nothing that the parents or families could have done any differently to prevent it. (Some things like smoking, alcohol, or other drugs, can slightly increase the odds.)

The premaxilla is the central part of the upper jaw. It extends from the forehead and nose, growing down from the frontonasal prominence.

From the sides, the lateral maxillary prominences come towards the middle to join with the frontonasal prominence.

When the lip doesn’t fuse on one side, a unilateral cleft lip is seen.

When both sides don’t fuse, a bilateral cleft lip occurs.

When the maxillary prominences don’t meet on the inside of the mouth, that is when a cleft palate occurs. (Specifically, of the secondary palate, the part posterior to the premaxilla.)

This sweet child is seen at 1 month after lip repair, eating well and thriving!
