For most patients, 500cc implants are big. In fact, for the average sized patient, if considering the biomechanical stress of an implant, a “large” implant probably begins at 350cc - 400cc. But implant size does (need to) vary based upon body habitus. A 260cc implant may give a petite woman a D-cup, but be insignificant for someone who is a muscular 5’10” tall.
There is significant morbidity associated with large implants: excessive skin stretching, the occurrence of stretch marks, aggravated implant descent below the level of the inframammary crease, thinning of the skin, wrinkling and rippling, breast ptosis, pseudoptosis, breast gland atrophy, etc. Some of these may occur soon after surgery, while others may occur in a more delayed fashion or over several years. Either way, these are sources of patient dissatisfaction, and the surgical correction is not always easy.
I do involve the patient in their implant sizing, but I prefer to follow a biodimensional philosophy for implant selection. I utilize measurements and other assessments of the breast-skin envelope to estimate the appropriate sized implant. This means that the diameter of the implant does not generally exceed the base width of the breast, that small tight skin envelopes require smaller implant volumes, and that more lax skin envelopes can accommodate larger volume implants. But in light of the potential morbidities listed above, just because there may be significant breast deflation and laxity does not mean that a large implant must be used to fill the breast back up; and so I am not afraid to also use a lift in those situations.
A successful operation, and a happy patient, is the result of good communication. I have detailed conversations with my patients regarding sizing, their desires, and the reasons why I believe biodimensional planning is important. I have patients perform sizing at home and/or in the office, and I also use intra-operative sizing to help make decisions.
My approach is individualized to each patient. I believe this approach minimizes stress to the breast, minimizes morbidity and associated re-operations, and yields better long term results. Utilizing this philosophy, I have re-operated on only two patients in the last twelve years to place larger implants; these re-operations were more than two years after the initial augmentation.
I know I don’t make the biggest breasts around…and I’m okay with that...and I know my patients are as well.
