1. Flat chest. If the breast tissue is scarce and the pectoralis major muscle is tense, the water drop type should be used to cut off the starting point of the pectoralis major muscle, so that the appearance of the standing position after operation is beautiful.
2. If the chest is very long and the shape is poor after placing a circular prosthesis, you should choose a water drop shape.
3. Thin skin. If a round prosthesis is used, the top of the breast will not look beautiful, and a water-drop breast prosthesis should be chosen; If the breast is thick and the thickness of the squeezed skin exceeds 3 cm, you can choose a round prosthesis.
4. If the breast droops slightly, you can use the high convex water drop type to improve it.
5. Ask and introduce to the patient himself: If the chest is beautiful and attractive when wearing a low-necked thin dress, a round prosthesis should be chosen, which can make the breast extremely full after operation; If you are more beautiful naked, you should choose a drop-shaped breast prosthesis.
