1. The space for placing the prosthesis on both sides is asymmetrical, or the space for placing the prosthesis is insufficient.

2. Prosthesis is not designed according to the shape of bridge of nose.

Maintenance plan:

Take out the previously implanted prosthesis, rearrange the space for placing the prosthesis, and finally implant the prosthesis suitable for the nose shape. The reason for this situation is not the side effects of the operation, but the strength of the surgeon. Therefore, we must find a professional doctor with rich surgical experience to ensure satisfactory surgical results.
