In order to simplify concepts can be said that there are two profile shape groups of breast implants, the spherical profile, also called round shaped, and other with anatomical profile, also called teardrop shaped. With both models patients can achieve good results however only with anatomical ones the outcome does reach an outstanding level of beauty and naturalness, thus making current surgical trends and preferences of patients massively prone for the use of anatomical models which are way more requested.
Nipple downwards both profiles have identical shape and provide the same breast effect, which is a round, curvy or belly shape contour, being the differences between their results visible only in the upper half of the breast; these differences are more remarkable the more slim or skinny the patient is, the less amount of own patient's breast tissue is supplied on top and the larger the patient wishes the size of the breasts.
The traditional and outdated breast implants profile shape is round shaped. These prostheses are unable to replicate the original structure of a natural breast, being round shaped at their lower half and equally round at the upper part of the breast and the cleavage; their main disadvantages are their less natural results, poor or insufficient fullness at the upper part of the breast and cleavage, forming a step or ball fake look at the cleavage and their inability to replicate the normal shape of a mammary mound being the desired size by the patient a relevant factor.
Round breast implants were the state of the art in the 20th century but are not any longer nowadays in breast surgery of any kind, primary or revisional, with or without association of breast lift mastopexy, breast reduction, tuberous breast correction, etc.
Should the patient wish safety, a round fake look and satisfaction not connected with beauty with greatest influence of the wished breast size and genetical body constitution the round profile breast implants might be valid but still the anatomical ones are neatly superior.
