The best way to treat a breast capsule during implant exchange depends upon several factors, the severity of the capsule being extremely important. In the case of having a Baker Class IV capsule (a breast implant capsule causing visible changes to breast appearance plus associated breast pain or tenderness), you were experiencing the most severe manifestation of this problem.
It isn't really possible for a Baker Class IV capsule to develop within 3 days of breast augmentation surgery, but when revision surgery, in the form of a breast implant exchange, is carried out with placement of the new implant into a position surrounded by the old implant capsule, quick re-formation of the capsule is a definite possibility.
Because of this known fact, there are established procedures for handling a prior capsule when placing a new implant. These recommendations can be ranked by complexity, effectiveness and cost, as follows:
Place the new implant into the old capsule, after weakening the capsule with multiple incisions to break up its tightness (capsulotomy). This is the least successful way to overcome a capsule problem, but it is least costly, and occasionally it succeeds. This method is frequently used when changing to new, larger size, implants.
Remove a large portion of the old capsule before placing the new implant into the capsule space (partial capsulectomy) or remove entire old capsule (total capsulectomy). Sometimes portions of the capsule are permitted to remain and hopefully provide reinforcement to maintain good implant position.
Put the implant in a new space, not into the old capsule space. This may be accomplished by changing the implant position from behind the muscle to in front of the muscle, or visa versa.
Create some of the new implant tissue coverage using a relatively new product derived from specially prepared animal collagen (Acellular Dermal Matrix). This has recently shown promise as being and effective way to avoid a capsule. Unfortunately, this is the most expensive of the methods!
From your description of your problem, it sounds as if your surgeon attempted solving your deflation & capsule problem, using one of the less costly options. If that has now failed, it's logical that you would next be offered a more involved (also more costly) approach.
I hope this explanation helps!
