Breast Reconstruction with Aeroform Tissue Expander

It seems like all the latest breast reconstruction techniques like Neopec come from Australia. Now the Australians have come up with a rapid way to expand chest skin after breast cancer mastectomy to allow placement of a breast implant and thereby reconstruct the breast (see my blog Reconstruction After Breast Cancer Surgery). Usually a saline balloon or expander is surgically placed and the surgeon then progressively fills it with salt water that is injected on a weekly basis to stretch the skin. This can take up to 6 months. Now they have devised an expander that contains a cylinder of compressed carbon dioxide gas. The patient controls the release of the gas into the expander with a handheld remote control and slowly expands on a daily basis.

Preliminary data reveal that using the Aeroform Tissue Expander the expansion can be completed in 17 days instead of 6 months. Enrollment in FDA clinical trials have begun in the US and the manufacturer is predicting a 2014 FDA clearance for general use.

Reconstruction After Breast Cancer Surgery

Breast cancer forms in tissues of the breast, usually the ducts (tubes that carry milk to the nipple) and/or lobules (glands that make milk).

It existence was acknowledged thousands of years ago. The ancient Egyptians in 1600BC described it as a “coagulum of black bile” within the breast and thought that getting rid of the excess bile¬ — through surgery, special diets, purging or even attaching leeches to draw out the bad blood— could cure the disease. In 1889, American surgeon William Halsted, a founder of renowned Baltimore teaching hospital Johns Hopkins, performed the first radical mastectomy removing the breast and underlying chest muscle in an attempt to cure the disease. It was not until the introduction of breast implants in 1963 that any reasonable breast reconstruction could be performed.

Breast Implants and Lymphoma Cancer

Patients with either saline- or silicone gel–filled breast implants may have a very small but significant risk for a rare cancer called anaplastic large-cell lymphoma (ALCL), a cancer of the immune system, adjacent to the implant. This is currently under investigation and its existence should be considered if there is a build up or collection around the implant (seroma) years after the original surgery. Because the risk is very small the current policy is one of data collection only and no changes have been recommended for the use of breast implants or the frequency of follow up after breast implant surgery. The FDA continues to state that breast implants are "safe and effective when used as labeled."

Breast Implants Augmentation Reconstruction and a Natural Look

Most of us know when we see a good result from breast surgery whether it be implants for breast augmentation or reconstruction after breast cancer surgery (mastectomy) or the results of a breast reduction surgery. As I described in my blog on facial proportions analysis a similar proportions assessment is used in planning any breast surgery and in assessing the end result.

That is to say for the average woman between 5 and 6 feet tall the desired proportions are that the nipples form an equilateral triangle with the upper notch of the breast bone and each side of the triangle is about 20cm in length. Additionally the distance between each nipple and the fold under the breast should be about 7cm with a gentle curve outline along the bottom of each breast. Together with equal sized nipple areola complexes this creates the left right symmetry and aesthetic look we strive for. The question then arises as to how one achieves this goal or result after breast surgery. This blog will only deal with breast implants rather than breast reductions and mostly with options available to correct for deviations from this pattern after breast implant placement i.e. redo breast implant surgery when the nipple is in the correct position.

New Discovery Could Make Breast Implants Obsolete

Earth shattering news out of Australia this week could have monumental effects on breast surgery, both reconstruction after breast cancer and enlargement for cosmetic reasons. The technique discovered in Australia is called Neopec. So far the process has only been performed in pigs and was so successful that human trials are scheduled too begin in early 2010. The pigs grew new breasts in 6 weeks. The surgeon places a scaffold or shell of biodegradable material in the breast, redirects a small blood vessel from the arm into the shell, places a small amount of the patient's own fat inside the shell, and a dissolvable gel called Myogel is also placed in the shell. The Myogel and blood flow from the transferred artery stimulate the fat to grow until it fills the shell and therefore takes the shape of the shell. This is a direct finding from stem cell research. After that the biodegradable shell is dissolved by the body. In the future the shell may come with its own artificial blood vessel.
