Question
Patient Age: Hello doctors, today I went for an anomaly scan at 22+4 weeks of pregnancy, and the ultrasound showed the child’s biparietal diameter (BPD) is 5.9 cm, but the nasal bone is only 0.49 cm.
Answer
Condition Analysis: At this gestational age, the nasal bone is typically around 0.8 cm, so yours is shorter than normal. I suggest a follow-up or further examination. Guidance: You can undergo chromosomal testing or a Down syndrome screening to check for any abnormalities. Currently, it cannot be accurately determined. We know that chromosomal abnormalities can cause significant harm to the child. If not treated promptly or with incorrect treatment methods, the progression can be rapid, posing great harm to the child. Therefore, it is crucial to seek timely and standardized treatment at a professional hospital.
