Saddle nose

A low nasal bridge is a flattening of the top part of the nose.

I Would Like to Learn About:

    Decreased growth (hypoplasia) of the nasal bridge may due to infections or genetic diseases. A decrease in the height of the nasal bridge is best seen from a side view of the face.

  • Causes

    • Cleidocranial dysostosis
    • Congenital syphilis
    • Down syndrome
    • Normal variation
    • Other syndromes that are present at birth (congenital)
    • Williams syndrome
  • When to Contact a Medical Professional

    Call your health care provider if you have questions about the shape of your child's nose.

  • What to Expect at Your Office Visit

    The health care provider will perform a physical exam and ask questions about the patient's family and medical history.

    Laboratory studies may include:

    • Chromosome studies
    • Enzyme assays (blood tests to measure specific enzyme levels)
    • Metabolic studies
