During early pregnancy, the tissues of the baby’s face and mouth grow towards each other and join.
A cleft happens when they do not fully close.
• Cleft lip: A gap or split in the upper lip. It can be on one side or both sides, and it can be small or
extend up into the nose.
• Cleft palate: A gap in the roof of the mouth. It may involve the hard palate at the front, the soft
palate at the back, or both.
• Cleft lip and palate together: Some babies have both.
It is not your fault. A cleft is not caused by anything a parent did or did not do. Parents often blame
themselves, but this is a developmental difference, and no one should feel guilty about it.
• Cosmetic (aesthetic) surgery, which reshapes normal features to improve appearance and confidence. So cosmetic surgery is one part of plastic surgery, not a separate field.
