Cronin and F.J. Gerow reported the first breast augmentation procedure using silicone gel-filled implants.
In 1972, J. Jenny described a periareolar-incision emplacement technique for inserting the breast implants via an incision under the nipple-areola complex (NAC).
In 1973, Koeller described a transaxillary breast implant emplacement technique effected by means of an incision to the axilla.
[3] In 1991 the trans-umbilical breast augmentation was invented and first performed by Dr. Gerald W. Johnson in Houston Texas.
A TUBA procedure is performed bluntly (without endoscopic assistance), and is inapplicable to emplacing (pre-filled) silicone-gel implants, because of the great potential for damaging the elastomer silicone shell of the breast-implant device during its manual insertion through the short, two-centimetre (3/4"), incision at the navel, and because pre-filled silicone-gel implants are incompressible, and cannot be inserted through so small an incision.
