There are two types of cleft lip:
- unilateral cleft - where the cleft occurs on one side of the lip
- bilateral cleft - where the cleft occurs on both sides of the lip.
The appearance of the cleft lip is variable among babies. It can be an incomplete cleft (a small notch in the lip) or a wide gap that runs all the way up to the nostril (complete cleft lip). The appearance of a cleft palate can be anything from an opening at the back of the soft palate towards the throat to an almost complete separation of the roof of the mouth.
