Bifid uvula

How it works

The uvula is the small teardrop of soft tissue that hangs from the back edge of the soft palate. It helps seal the nose off from the mouth during swallowing, and it adds saliva to the throat¹. A bifid uvula is split down the middle into two lobes, anywhere from a small notch at the tip to a full division¹⁵.

The palate forms in the embryo from two shelves of tissue that grow toward each other and fuse from front to back⁴. The uvula is at the back end, so it is the last part to join⁴. If fusion stops just short of finishing, the uvula is left with a split. That makes bifid uvula the mildest possible form of cleft palate¹⁴. It often runs in families.

How common it is

The 1% to 2% figure is a middle value, and single studies range from 0.44% to 3.3%¹⁵. The wide gap between that figure and the 10% to 20% seen in some Native American groups shows how much prevalence depends on which population is studied¹⁶. Because a small notch can be easy to miss on a quick look, mild cases are likely undercounted, so the true figure may run a little higher.

Try it

1. Stand in front of a mirror in good light, or use a torch.
2. Open wide and say “ah”. This lifts the soft palate and shows the uvula.
3. Look at the tip of the uvula. A bifid uvula has a notch, a Y shape, or two separate hanging lobes.
4. If you cannot see well, ask someone else to look while you say “ah”.

Is it a problem?

In an older child or adult, almost never. A split uvula has less muscle than a single one¹. It often causes no symptoms at all⁴.

In a baby, a bifid uvula deserves a proper look. It can be the only visible sign of a submucous cleft palate, a gap in the muscle of the soft palate hidden under an intact lining². That can cause milk to come out of the nose during feeds, ear infections, and later a nasal-sounding voice³⁴. A doctor checks by feeling the back edge of the hard palate for a notch and by watching how the soft palate moves²⁴. If speech, feeding and the ears are normal, doctors usually just watch it⁴. They take extra care before they remove the adenoids⁴.
