Maxwell is credited with a significant advancement in the design of tissue expanders used for breast reconstruction by co-developing textured surfaces [2] [3] (to decrease capsular contracture) and helping to introduce prostheses which more closely resemble the shape and feel of the natural breast. The two-stage method of expander-implant ...
Tissue expansion is a common technique used for breast reconstruction. [20] This essentially involves expansion of the breast skin and muscle using a temporary tissue expander. [21] Three to four weeks after the mastectomy, a saline solution will be injected into the expander to gradually fill it. This process is supported by a tiny valve ...
In particular, breast ultrasound may be useful for younger women who have denser fibrous breast tissue that may make mammograms more challenging to interpret. [ 3 ] [ 4 ] Automated whole-breast ultrasound (AWBU) is a technique that produces volumetric images of the breast and is largely independent of operator skill.
In doing so, the tissue expander prevents the breast tissue from contracting and allows for use of a larger implant later on compared to what would be safe at the time of the mastectomy. [3] Following this initial procedure, the patient must return to the clinic on multiple occasions for saline to be injected into a tube inside the tissue expander.
Breast ultrasounds may be used with or without a mammogram. Breast ultrasound is the use of medical ultrasonography to perform imaging of the breast. It can be used as either a diagnostic or a screening procedure. [38] It may be used either with or without a mammogram. [39]
MSOT illuminates tissue with light of transient energy, typically light pulses lasting 1-100 nanoseconds. The tissue absorbs the light pulses, and as a result undergoes thermo-elastic expansion, a phenomenon known as the optoacoustic or photoacoustic effect. This expansion gives rise to ultrasound waves (photoechoes) that are detected and ...
DIEP flap breast reconstruction is typically performed by the Plastic Surgery team (rather than the Breast Surgery team) so is only available in centres with Plastic Surgery support. It is a more complicated operation than other autologous or alloplastic options, but provides significantly better cosmetic results, which means better ...
Ultrasound can ablate tumors or other tissue non-invasively. [4] This is accomplished using a technique known as high intensity focused ultrasound (HIFU), also called focused ultrasound surgery. This procedure uses generally lower frequencies than medical diagnostic ultrasound (250–2000 kHz), but significantly higher time-averaged intensities.
