Cleft lip and palate can be divided into simple cleft lip and the combination of cleft lip and cleft palate.

A simple cleft lip only affects one's appearance and pronunciation. However, a cleft palate can sometimes affect one's ability to eat and may cause choking easily.

There are several stages of surgeries for cleft lip and palate. Generally, patients may need to undergo second or third - stage surgeries later.

When it comes to whether it can be completely repaired, I think there's no problem in restoring the function. But any surgery will leave scars. It won't be as perfect as if no surgery had been done, and usually, it can be noticed from the appearance.
