May affect the overall appearance. Of course, if the deformity is not particularly obvious, it can be changed by plastic surgery after the baby grows up. Hello, it is up to you to consider your situation. If you think you can put a nasal bone on your nose through surgery later, it's not a big problem. The absence of nasal bone is also a deformity. Opinions and suggestions: the lack of nasal bone is actually not a big problem. Now that plastic surgery is relatively mature, you can find an authoritative hospital for plastic surgery. Then the possibility of dysplasia cannot be completely ruled out. In general, the probability of nasal bone loss is relatively small. It is also possible that the fetal position is not good and cannot be observed when doing B-ultrasound. I suggest you check it again in a week or two. It may be because of the influence of body position, or it may be because of the imperfect development of the fetus, so it is impossible to clearly rule out whether the fetus is deformed at this stage. You can wait until 0/6 weeks after pregnancy, and make a definite diagnosis through further examination.
