Clinical and radiological (X Ray) tests of the breasts are required.
Biology: Usual pre-operative tests.

This is either performed through a peri-areola scar (i.e. around the circumference of the areola), or in worse cases is performed using a keyhole incision - with the resultant scar around the areola and a very small and insignificant scar in the inframammary fold. A vertical scar joins these 2 scars. All sutures are absorbable and do not need to be removed. Post-operatively the patient has to wear a bra for 4 weeks day and night.

One hour and 30 minutes.

After breast uplift surgery, you'll wear an elastic bandage or a surgical bra over gauze dressings. Your breasts will be bruised, swollen, and uncomfortable for a day or two, but the pain shouldn't be severe. Any discomfort you do feel can be relieved with medications prescribed by your surgeon.
Within a few days, the bandages or surgical bra will be replaced by a soft support bra. You'll need to wear this bra around the clock for three to four weeks, over a layer of gauze. The stitches will be removed after a week or two.
If your breast skin is very dry following surgery, you can apply a moisturizer several times a day. Be careful not to tug at your skin in the process, and keep the moisturizer away from the suture areas.
You can expect some loss of feeling in your nipples and breast skin, caused by the swelling after surgery. This numbness usually fades as the swelling subsides over the next six weeks or so. In some patients, however, it may last a year or more, and occasionally it may be permanent.

Your surgeon will make every effort to make your scars as inconspicuous as possible. Still, it's important to remember that mastopexy scars are extensive and permanent. They often remain lumpy and red for months, then gradually become less obvious, sometimes eventually fading to thin white lines. Fortunately, the scars can usually be placed so that you can wear even low-cut tops.
You should also keep in mind that a breast lift won't keep you firm forever--the effects of gravity, pregnancy, aging, and weight fluctuations will eventually take their toll again. Women who have implants along with their breast lift may find the results last longer.
Your satisfaction with a breast lift is likely to be greater if you understand the procedure thoroughly and if your expectations are realistic.
