A short philtrum is a shorter than normal distance between the upper lip and the nose.
The philtrum is the groove that runs from the top of the lip to the nose.
The length of the philtrum is passed down from parents to their children through genes. This groove is shortened in people with certain conditions.
- Chromosome 18q deletion syndrome
- Cohen syndrome
- DiGeorge syndrome
- Oral-facial-digital syndrome (OFD)
There is usually no home care needed for a short philtrum. However, if this is only one symptom of another disorder, follow your doctor's instructions on how to care for the condition.
