On July 24, 2019, Allergan announced a global recall of Biocell textured breast implants and tissue expanders after the U.S. Food and Drug Administration (FDA) requested the recall. The recall comes after a rare type of cancer called anaplastic large-cell lymphoma (ALCL) has been linked to textured breast implants.

Accordingly, how long can tissue expanders be left in?

Once you are happy with your breast size, the tissue expander will be left in place for a few weeks for maximal tissue expansion. The earliest your reconstruction surgery can be performed is three weeks after your final expansion visit.

Additionally, why are tissue expanders so uncomfortable? Before this procedure, you'll need tissue expanders—temporary, inflatable breast implants designed to stretch skin and muscle so your chest can accommodate the permanent implant. Because of the stretching involved, tissue expanders can be painful.

Subsequently, one may also ask, are tissue expanders MRI safe?

Introduction. Ferromagnetic port-containing breast tissue expanders are currently labeled MRI-unsafe because of the presumption that magnets should not enter the machine. However, designating these devices as MRI-unsafe can lead to unnecessary procedures or suboptimal imaging choices.

Can you swim with tissue expanders?

You cannot perform house hold chores or heavy lifting greater than 5 to 10 pounds for 6 weeks post-operatively. No hot tubs, swimming in lakes while the tissue expander is in place. Be Aware: You cannot have an MRI if you have tissue expanders in place.

Can you sleep on your side with tissue expanders?

The Best Sleeping Positions if You Have Tissue Expanders

During the first two weeks after your expander placement, you should sleep on your back. After two weeks, you can continue sleeping on your back or begin sleeping on your side. Some women find that cradling a pillow makes side-sleeping more comfortable.

Do you need to wear a bra with tissue expanders?

After 14 days you may remove the Surgical Bra and wear a “sports” type bra that will provide support and maintain the placement of the tissue expander. Please do not wear an underwire bra. Please wear a “sports” bra for 24 hours a day for 21 days. You may remove the bra to shower.

Do tissue expanders move around?

Although rare, there are warnings that the saline valve could leak, the tissue expander may move or slip in the chest, or that scar tissue can impact the expander. The other downside is the discomfort that some women feel while the tissue is expanding, which is described as tightening in the chest.

Why do I need tissue expanders?

Tissue expanders can also be used to prepare the skin for flap reconstruction, or as a first step while you decide what type of reconstruction to have. Even if you plan to have direct-to-implant reconstruction, your surgeon may find out during the surgery that a tissue expander is needed instead.

Can you sleep on your side after mastectomy?

While it is possible to sleep on your side after breast surgery, it comes with some medical concerns that aren't worth the risk. Instead, most plastic surgeons recommend that patients who have had breast surgery sleep exclusively on their backs until they are fully healed.

How can you tell if a tissue expander is infected?

Sometimes a bacterial infection can develop in the tissue around a breast implant or tissue expander during the days or weeks following the reconstruction surgery. Symptoms of an infection can include a high fever and breast pain, redness and/or swelling.

Are implants more comfortable than expanders?

They also tend to restore the feel of breast tissue better than saline due to their cohesive viscosity. After the permanent implant has been placed you will immediately feel more comfortable than when the expander was in place. The tightness will decrease quickly as the implant settles into the pocket.

Can you exercise with breast expanders?

If you have a tissue expander in (a temporary inflatable implant that stretches the skin to make room for the final implant), you can usually start gentle shoulder stretching exercises about 2 weeks after surgery once your mastectomy scar has started to heal.

What is a tissue expander made of?

According to the FDA, the device has two main components: the expander, a sterile implant with an outer shell made of silicone, and the controller, a remote dosage controller. The expander contains a reservoir of compressed carbon dioxide.

How long do Mentor implants last?

The accepted medical advice is that they last 10-12 years and patients should have an MRI scan after 3 years and then 2 yearly after that to monitor their implants.

What does tissue expander look like?

A tissue expander looks a lot like a breast implant, although it has a thicker outer shell than breast implants. There is a port on the front of the expander.

What happens after tissue expander surgery?

Your Recovery

Right after the surgery you will probably feel weak, and you may feel pain for 2 to 3 weeks. You may have a pulling or stretching feeling in your breast area. You can expect to feel better and stronger each day, although you may need pain medicine for a week or two.

Are implants softer than expanders?

Implant Reconstruction Procedure

Often the skin is stretched slightly more than needed because it has a natural tendency to shrink when the tissue expander is removed. The permanent implant will either be filled with saline or silicone and will be much softer than the tissue expander.
