The Shapes of Breast Implants
The shape of the breast implant is either round or tear drop, with different base widths and projections.

Round implants have a round base. In round implants with the same volume, the width of the base determines the projection (profile) of the implant. The narrower the base is, the higher the projection (profile of the implant).

Tear drop (anatomical) implants look like a tear drop when viewed from the side.

The upper half of the implant is flatter and the lower half is fuller. Tear drop implants come with different bases and heights, which affect their projection (profile). The surface of all tear drop implants are textured. There are markers on the surface of the tear drop implants to guide the surgeon to align the implant in a correct position.

After breast enlargement, there is always a risk of the breast implant rotating (spinning) in its pocket (space). When a round implant rotates, the shape of the breast is still the same. However, when the tear drop implant rotates, the shape of the breast will become distorted. There is the very small risk of this happening. The textured surface of the tear drop implant, use of drains and wearing of stabilizers after the operation helps prevent this rotation from happening.

Tear drop implants also have a slightly lower incidence of capsular contracture (thick scarring around the implant). This is because of its shape and its textured surface.
