Fetal nasal bone dysplasia needs to be clarified as to its etiology. If the dysplasia is simple, the pregnancy can be continued and treated after birth. If the chromosomal abnormality is present, the pregnancy should be terminated. Fetal nasal bone dysplasia can be detected by ultrasonography, and further examination should be carried out in the presence of nasal bone dysplasia, which can be diagnosed by amniocentesis. If it is just a simple dysplasia of the fetus, the pregnancy can be continued, and the nasal bone may return to normal as it develops, or the appropriate treatment can be carried out after birth. If the test is a chromosomal abnormality, you can consult your doctor and choose to terminate the pregnancy promptly if it cannot be preserved. During pregnancy, you should avoid exposure to harmful substances, do not abuse drugs, and should consult a doctor when discomfort occurs.
