Breast implant
Since the late nineteenth century, breast implants have been used to surgically augment the size (volume), modify the shape (contour), and enhance the feel (tact) of a woman's breasts. In 1895, surgeon Vincenz Czerny effected the earliest breast implant emplacement when he used the patient's autologous adipose tissue, harvested from a benign lumbar lipoma, to repair the asymmetry of the breast from which he had removed a tumor. In 1889, surgeon Robert Gersuny experimented with paraffin injections, with disastrous results.
Breast augmentation
The fat graft breast reconstructions for 33 women (47 breasts, 14 irradiated), whose clinical statuses ranged from zero days to 30 years post-mastectomy, began with the pre-expansion of the breast mound (recipient site) with an external vacuum tissue-expander for 10 hours daily, for 10–30 days before the first grafting of autologous fat. The breast mound expansion was adequate when the mastectomy scar tissues stretched to create a 200–300 ml recipient matrix (skin envelope), that received a fat-suspension volume of 150–600 ml in each grafting session.
