Bilateral tissue expanders during breast reconstruction

They are filled in stages through built-in ports, allowing the skin and soft tissue to stretch before exchange for implants or another planned reconstruction.

A surgeon usually places an expander beneath chest muscle or in a supported space above it, depending on the operation and tissue condition. The two sides may heal or expand at different speeds. Unevenness during the process can occur because fill volumes are adjusted to each side rather than simply matched.

Expansion appointments are tailored to comfort, wound healing and the reconstruction goal. You may notice pressure or tightness after a fill. The reconstruction team decides when enough space has been created and when it is appropriate to proceed to the next operation.

Follow the surgical team's instructions for wound care, showering, support garments and activity. Keep scheduled visits so both the skin and expander position can be checked. Before exercise, driving, lifting or sleeping on your side, confirm what is suitable for your stage of recovery.

Record any change that differs between the sides, including increasing firmness, swelling, redness or a shift in shape. Tell clinicians that you have expanders before imaging or another procedure, and carry the device information supplied by your team.

Call the reconstruction team promptly for fever, spreading redness, warmth, drainage, a wound opening, worsening swelling, new skin darkening, severe tightness, sudden shape change or pain that is not controlled by the advised medicines. Seek emergency help for difficulty breathing, fainting, sudden chest pain, confusion or a severe allergic reaction.

Ask where each expander sits, how filling decisions will be made, which sensations are expected after appointments and what asymmetry may be temporary. Confirm restrictions that apply to your work and daily routine, the contact route for urgent concerns, and the options planned after expansion.
