Under the muscle, over the muscle, dual plane, what does it mean ?
Breast implants can be placed in front of or behind the pectoral muscle. The pectoral muscle is the muscle located in the chest, under the woman’s breasts. This muscle is large, powerful and placing implants under or over it for breast augmentation purposes doesn’t cause functional issues.
Naturally, the mammary gland is located in front of the pectoral muscle. However, if the patient has a thin skin (which is assessed during the clinical examination by the pinch test), placing breast implants in front of the muscle can cause the implants to be visible. The implants being visible negatively impact the result which tends to look unnatural. In this case, surgeons usually place the implants behind the pectoral muscle in order for the upper pole of the implant to be well concealed.
The term ‘dual plane’ means that the implant is covered by two types of tissues : the upper pole of the implant is covered by the muscle whereas the lower part is hidden behind the mammary gland.
How to choose breast implant size
While breast implant size can be chosen by the patient, her frame narrows down her choices. The perception of beauty remains subjective, and depending of the patient’s morphology, the ideal implant size will vary. This is why choosing an implant size before the consultation isn’t a good idea as the same size won’t look the same on different patients.
One of the main factors to take into account is the base width of the breasts. Ideally, the implants size corresponds to the breasts base width in order for the result to be as natural as possible and for the breast to be full. During the consultation, patients can use trial implants to get a better idea of what their breasts will look like after surgery.
