Preoperative Sizing in Breast Augmentation

Background: Implant size selection in breast augmentation patients is one of many variables to be determined before surgery. Few methods exist today that allow the patient to participate in this process and accurately determine optimal size. The authors describe a simple method of preoperative sizing using silicone implant samples. Methods: A total of 567 patients underwent breast augmentation: 297 had surgery before implementation of preoperative sizing and 270 patients were sized preoperatively. Sizing consisted of fitting the patients with various size silicone implants in a larger bra at least twice before surgery to determine desired size. Surveys were sent to both groups to inquire about overall satisfaction, how many preferred a different size postoperatively, and how many ultimately un­derwent size change surgery. Results: One hundred two responses (34.3 percent) were obtained from the control group and 142 (52.6 percent) were obtained from the sized group. Sized patients received smaller implants (average, 276.6 cc nonsized versus 246.4 cc sized; p ! 0.001). Four patients (1.4 percent) in the control group underwent a size change procedure compared with none in the sized group. In the sized cohort, 69 percent believe they are the size that the process predicted, 21 percent are smaller, 9 percent are larger, and 1 percent did not answer the question. Conclusions: Sized patients were more satisfied than controls and fewer were interested in having a different size implant postoperatively. Sized patients indicated that preoperative sizing was both helpful and reasonably accurate in predicting final breast size. (Plast. Reconstr. Surg. 125: 1781, 2010.)
atients pursuing breast augmentation have many options to consider before surgery,
P
plane, and multiple implant factors such as filler type, shape, profile type, texture, volume, and sometimes manufacturer. Implant diameter is an­other important variable, although it is less obvi­ous to the layperson. Some have additional factors to consider such as the need for a simultaneous mastopexy that can be performed by several dif­ferent methods and may be unilateral, bilateral, or require a different approach on each side. An­cillary procedures such as correction of inverted nipples or nipple reduction in the postpartum patient are options that add to the decision-making process.

Most patients today conduct considerable re-
tive surgical plan. Arguably the most elusive factor to settle with certainty before surgery is implant size. Many patients have fixed notions of size based either on cup size, celebrity or Internet photo­graphs, the experience of friends (both good and bad), or their personality. However, none of these factors is of proven benefit in selecting the proper implant size.
Verbal communication alone between the pa­tient and physician, even if supplemented with adjunctive information as described above, is an unreliable method for determining implant size. When the decision is perceived to be a unilateral one on the part of the physician, the patient does not feel compelled to accept responsibility for that decision if she is disappointed after surgery. The need for additional surgery for a size change is associated with anxiety, urgency, and the belief that the surgeon is at fault or at least should bear the responsibility for the cost of replacement sur-

gery. Some surgeons tend to use a size larger than may be necessary to hedge their bets and avoid this situation, often perpetuating the folklore that pa­tients always wish they were a little larger anyway.
Some practitioners have attempted to use a com­bination of chest wall measurements and “bust cir­cumference” to determine implant size, whereas others have constructed tables that correlate implant

volume with bra size for reference.
Others rely on
a set of specific tissue characteristics and measure-
3–6
ments to determine optimal implant size.
Al­though this latter method seeks to make size se­lection more scientific, it ultimately presents optimal size to the patient as a fait accompli with­out participation beyond her anatomy. This does not guarantee a happier patient, although it may provide the surgeon with stronger footing for dis­couraging pursuit of size change surgery later.
Many experienced surgeons seek to have the patient more actively involved in size selection in a way that will help preview the result. Some have described using rice or saline in a bag to estimate
7–9
the size of the implant required.
Today, there are Web sites on the Internet that describe the “rice test” for prospective patients to perform at
10,11
home.
A method of preoperative sizing that the authors have been using for the past several years and that constitutes the basis for this report consists of fitting patients with their desired bra size and placing various size sample silicone gel implants in the bra to simulate the result that each size would achieve (Fig. 1). This allows the patient to preview final breast size and, by participating in the sizing process, accept responsibility for the outcome together with the surgeon. The goal is to minimize the prospect for patient dissatisfaction
after surgery that can ultimately lead to secondary surgery to change implant size.
PATIENTS AND METHODS
Technique of Preoperative Sizing
Preoperative sizing is performed at least two times before surgery. The first session is generally more time consuming and is usually done with the nursing staff, whereas the second session is done with the surgeon, as it is either largely confirma­tory or the surgeon can give additional input to guide the process. Patients unable to clearly state a narrow range of preferred sizes are brought back for a third visit if necessary. The goal is to narrow the choice down to two sizes differing by not more than 25 cc. Patients are advised that this narrow range represents approximately one-eighth of a cup size and the final selection thereafter is best left as an intraoperative decision.
The process begins by fitting the patient with a larger bra that has underwires but minimal pad­ding. This is most often a C cup, althoughaDcup may be used in some young nulliparous patients and a B cup in some older and more conservative postpartum patients. The chest circumference is variable and generally the same as the patient normally wears (even though many patients do not necessarily wear the correct size bra for their
12
chest circumference). the bra cup material adds volume by itself and that this varies depending on the type of bra. In our sizing bra, the extra volume measured 30 cc per side (Fig. 2). This volume can be added to the final size implant preferred by the patient during
Patients are advised that

the sizing process if she seeks the outside volume that includes the bra.
The starting point in implant sample size is somewhat arbitrarily determined by taking into account height, weight, personality, and specific goals. Two different sizes are placed and the com­bination gradually increased until the patient feels the goal has been achieved. A common starting point is a 225-g implant on one side and a 250-g size on the other and working up (or less com­monly down) from there. A thin form-fitting top is typically worn to examine the effects of the different sizes in front of a full-length mirror (Fig. 3). Once the patient has determined the desired size range, it is important to continue the process, placing larger sizes until they emphati­cally state “that is too much.” This final step in the sizing process can be helpful postoperatively in preventing a patient from lamenting that maybe she should have tried on a larger size.
It is generally best not to have friends or family members present during the sizing process, at least not during the first session. They may have aesthetic values that differ from those of the pa­tient and sometimes have a relationship that may be competitive or otherwise emotionally charged. Supportive spouses and significant others are usu­ally an asset, although in some cases the partner may harbor a different agenda regarding size.
The second visit with the physician serves to confirm the size preferred and allow for a con­versation on how anatomy may either impose some restrictions regarding the size selected or suggest the use of a larger size than previously considered. Patients with either a narrow breast base (such as tubular breasts), poor postpartum skin elasticity, or a sharply defined inframammary crease located close to the areolar margin may require a smaller implant size than they prefer. In contrast, tall patients and those with a wide chest may benefit from greater volume and diameter than they thought was ideal. This meeting is also useful to decide which incision will be best. Some­times, for example, the patient preferring a some­what larger silicone implant may no longer be a candidate for a periareolar incision if her areolar diameter is small. An inframammary crease inci­sion usually proves necessary in such a case.
Although sizing is performed with silicone im­plant samples, the process is the same for patients using saline implants. The saline implant size se­lected is one size smaller than the silicone sample. This allows overfilling to the desired volume to minimize the prospect of ripples and possibly pre­mature deflation. For example, a patient who likes
a range between 275 and 300 g would be well suited for either a 250-cc implant or a 275-cc im­plant overfilled to achieve the same final volume range. As a practical matter, saline implant size is assumed to correspond in cubic centimeters to the size selected in grams of silicone.
Data Collection
A questionnaire was sent to a control group consisting of patients operated on between March 3, 2003, and October 6, 2005, and a sized group operated on between October 10, 2005, and July 16, 2008; all procedures were performed by the senior author (D.A.H.). The goal was to assess satisfaction with the procedure in general and with size specifically, at an interval of at least 6 months after surgery (Fig. 4). Patients who were sized preoperatively were sent a second question­naire that inquired specifically about the sizing process (Fig. 5). Nonresponders to mail inquiry were called by phone to maximize the response rate.
Statistical Analysis
A two-sample independent measures t test was performed to analyze implant volume in breast augmentation patients treated with or without our preoperative sizing device. Cohen’s d was reported to show the size of the treatment effect (by con­vention, 0.2 ! d ! 0.8 corresponds to a medium effect size). Fisher’s exact test was used to evaluate wanting smaller or larger breast augmentations following surgery in patients treated with or with­out our preoperative sizing device. The Wilcoxon rank sum test was performed to assess the data obtained from the questionnaires. Results for ra­tio data were reported as mean " SE and those for ordinal data were expressed as median and cor­responding interquartile range. In all cases, the level for statistical significance was set at p ! 0.05.
RESULTS
The control group consisted of 297 patients and the sized group contained 270 patients. One hundred two responses (34.3 percent) were ob­tained from the control group and 142 (52.6 per­cent) were obtained from the sized group. Four­teen percent of surveys in the control group and 12 percent in the sized group were returned be­cause of change of address with no forwarding address available. The median interval between surgery and the survey response was 21 months in the control group (interquartile range, 9 to 71 months) and 12 months in the sized group (in-

Preoperative sizing allows the patient to par­ticipate in size selection. This imparts a sense of responsibility for the final result that does not exist in cases where the physician unilaterally decides optimal volume. It also allows the patient’s spouse, significant other, or key family member(s) to par­ticipate in the process. Although the latter has the potential to cause confusion because of a diversity of opinion, it more often than not is helpful in finalizing a narrow size range from which the pa­tient can choose.

the result and assess her appearance in a variety of clothing types. It also serves as a basis for dialogue between the physician and patient to take into ac­count other factors that influence final size selection. For example, patients often have to be urged to consider larger sizes because even conservative size implant samples can initially seem to make a dras­tic difference. In addition, patient height, chest width, and lower body contour are important fac­tors that may argue for either a larger or smaller size depending on particular anatomy and patient-
3–5
specific tissue characteristics.
Other anatomical constraints such as a sharply defined inframam­mary crease that is located relatively close to the inferior areolar margin will often impose limits on
13
implant diameter.
Placing an implant that is too large in this particular setting is a common cause of “double-bubble” deformity. Tubular breast shape, although fortunately uncommon, is a more extreme example of a situation where anatomy limits implant choice.
Preoperative sizing allows the surgeon to prop­erly counsel the patient on the issue of volume versus diameter as it pertains to specific anatom­ical characteristics. This will minimize the possi­bility of creating a postoperative shape problem as a result of using implant volume as the dominant criterion for size selection. Moreover, it will allow the physician to consider early on in the process alternate implant types to arrive at the optimal volume-to-diameter ratio. For all of these reasons, the surgeon should be intimately involved in the sizing process and not delegate this entirely to the nursing staff.
Some believe that sizing underestimates the final result because some of the volume is “lost” when placed in a retropectoral plane, an idea that is based on conjecture at best, not fact. It has not proven necessary to arbitrarily increase the im­plant size beyond that which the patient has cho­sen to accommodate this notion. However, it is important to make the patient aware that the bra itself can add as much as 30 cc volume depending on the type (Fig. 2).
Another common practice is for surgeons to err on the larger side when it comes to selecting implant size to avoid the unhappy patient who may
14
then seek size change surgery.
It could be argued that postoperative problems such as double-bub­ble deformity and others may occur less com­monly if implants are not routinely picked slightly larger than what appears good to make certain that the patient is happy with size selection. Although downsizing implants is less common than a request for larger implants, the former scenario does occur
and may also be a result of this practice. As this study demonstrates, somewhat smaller implants can be used without compromising patient satis­faction when preoperative sizing is incorporated as an integral part of preoperative preparation.
Another advantage of preoperative sizing is that two different size implants can be tested si­multaneously in patients with volume asymmetry. This will aid both the patient and the physician in deciding whether or not to use different sizes in those whose breasts differ in small volumes and how many sizes different may be needed in those with greater volume differences.
The average implant size used in this study is relatively small and likely reflects the study pop­ulation treated. The senior author’s breast aug­mentation patients reside in the Northeast, a re­gion arguably more conservative than other (i.e., warmer) parts of the country. Also, most are post­partum patients seeking volume restoration more than significantly larger breast size. There is no reason to believe, however, that the practice of preoperative sizing would not be of equal value in practices where implant volumes average higher by 100 cc or more.
Interestingly, this study shows that a similar proportion of both sized and unsized patients wish to be a different size postoperatively, usually larger. Although the difference in revision rates between groups did not reach statistical signifi­cance (potentially because the low incidence of revisions in both groups), none of the patients in the sized group underwent size change surgery. This supports the assertion that patients who par­ticipate in size selection assume at least as much responsibility for the final choice as the surgeon. They are more willing to accept the result that they have without indulging in an ongoing mental de­bate that ultimately leads to further surgery.
Retrospective studies have well-known limita­tions, and studies using surveys suffer from incom­plete response rates. Despite these limitations and the fact that the data did not often show statisti­cally significant differences in patient satisfaction or revision rates, our clinical impression remains that preoperative sizing is quite useful. We believe this simple technique can easily be incorporated into the practice of any surgeon performing breast augmentation. Routine use of preoperative sizing in our practice has virtually eliminated the occur­rence of frantic early postoperative telephone calls from patients who feel they are too small. It has reduced patient anxiety more than any other fac­tor and has transformed the care of the breast augmentation patient in our practice into a more

uniformly rewarding and positive experience for both the patient and physician.
CONCLUSIONS
Although preoperative sizing is a highly sub­jective process, it has nevertheless proven to be a valuable tool in the management of a challenging patient population. Patients tend to be happier with their result than those who do not undergo preoperative sizing. Although some patients are not completely satisfied with their size despite pre­operative sizing, they rarely seek size change sur­gery. It is expected that future improvements in methodology and equipment will improve the pre­cision of the technique.

Background: Breast augmentation by autologous fat transfer is an appealing alternative in need of scientific validation. Methods: In a prospective multicenter study, 81 women (age range, 17 to 63 years) wore the Brava device, a bra-like vacuum-based external tissue expander, for 4 weeks and then underwent autologous fat injection using 10 to 14 needle puncture sites into each breast in a three-dimensional fan­ning pattern (average, 277 ml volume injected per breast). Patients resumed Brava wear within 24 hours for 7 or more days. Pretreatment and post­treatment breast volumes were derived from three-dimensional volumet­ric reconstruction of magnetic resonance imaging scans, and outcomes were compared with a meta-analysis of six recent published reports on autologous fat transfer breast augmentation without expansion. Follow-up ranged from 12 months to 6 years (average, 3.7 years). Results: Breast volume was unchanged between 3 and 6 months. Sev­enty-one of the treated women were compliant with Brava wear and had a mean augmentation volume at 12 months of 233 ml per breast compared with 134 ml per breast in published series without Brava (p < 0.00001). Graft survival was 82±18percent compared with 55±18percent with­out Brava (p < 0.00001). There was a strong linear correlation (R 2=0.87) between pregrafting Brava expansion and the resultant breast augmenta­tion. There were no suspicious breast masses or nodules. Magnetic reso­nance imaging recognized a 16percent incidence of fat necrosis easily identified at 1-year mammographic evaluation. Conclusion: The addition of Brava expansion before autologous fat grafting leads to significantly larger breast augmentations, with more fat

There­fore, in 2007, the American Society of Plastic Surgeons commissioned a Fat Graft Task Force that concluded that autologous fat transfer might be used for the breast “while the techniques and the results vary…. leaving a tremendous need for high quality clinical studies.”25 In 2009, the American Society of Plastic Surgeons lifted
PATIENTS AND METHODS
This study was designed to optimize all potential vari­ables. This includes low-pressure atraumatic fat harvest, minimal graft manipulation, and meticulous microdrop­let grafting. Because a larger recipient has room in which to safely graft larger volumes and because it is well proven that Brava expansion enlarges the recipient breast, we found it unethical to randomize Brava patients versus nonexpanded controls and arbitrarily condemn women to the morbidity and risks of surgery for a less eective procedure. Furthermore, because there are multiple recent peer-reviewed reports of autologous fat transfer breast augmentation without expansion, we elected to compare our Brava-expanded cohort to a meta-analysis of this well-established baseline.

the ban on fat grafting for breast reconstruction while recommending cautious use for augmentation26 because of concern for safety and ecacy, given the paucity of scientific studies.
Breast augmentation with liposuctioned fat has suf­fered from two fundamental limitations: the volume of fat that can be transferred in a single session and theper­centage graft survival.

In fact, there seems to be an inverse relationship between the two (i.e., the more fat grafted, the lower its survival rate).28 Eorts at overcoming this have focused on harvesting techniques, fat manipula­tion, stem cells, and related approaches.

To preserve the graft-to-recipient interface critical for
mentation with Brava Enhanced Autologous Fat Micro Grafting Protocol No. 2004-2, IRB COMM. No. 167), 81 women (Miami Breast Center, Key Biscayne, Fla., n =59; Caritas-Krankenhaus St. Josef, Regensburg, Germany, n = 12; Harley Medical Center, London, United Kingdom, n=10) who desired breast augmen- tation, were averse to implants, and who tolerated a 20-minute Brava test trial in the oce were enrolled in the study. We performed 77 bilateral and four uni­lateral autologous fat transfer breast augmentations on 170 breasts. Patient ages ranged from 17 to 63 years and body mass index ranged from 15 to 28 (average,
19.8). Smokers were excluded. All enrolled were grafted despite wide variation in compliance with the requested pregraft Brava treatment1 and despite the fact that four patients were noncompliant. Six patients did not return
for follow-up magnetic resonance imaging, and although revascularization and survival, fat grafts have to be dis­persed as microdroplets. Because in the small breasts to be augmented there is physically no room for dispersal without crowding a large quantity of microdroplets, we postulated that preparation of the recipient breast by external expansion is the key missing ingredient.
The Brava device has been on the market for over 10 years as an external soft-tissue expander and has demonstrated modest, permanent augmentation after long-term use.

Short-term use of Brava, however, causes a marked temporary increase in breast size and generates a very large fibrovascular scaold that would be an ideal recipient for fat grafts (Khouri RK, personal observation). We undertook this multicenter, prospec­tive, magnetic resonance imaging – documented study to determine the safety and ecacy of single-stage large­volume autologous fat transfer to the breast treated with
self-reports indicate they are complication-free, postpro­cedure breast volumetric measurements were not taken. Six of the earlier patients later underwent grafting a sec­ond time. However, we only analyzed the outcome of their first graft. Figure1 shows the breakdown of the treated and compliant patient groups.
Before Brava expansion and in phase with her men­strual cycle, every woman underwent baseline magnetic resonance imaging with breast coils, intravenous gado­linium contrast, and fat subtraction. The patients were asked to wear the Brava external breast tissue expander for 10 hours/day for 4 weeks. This preexpansion period increases the vascularity of the recipient site.

For the last 36 to 48 hours, they were asked to maintain unin­terrupted expansion and come to the operating room still wearing the expander, to induce an immediate tem­porary three-dimensional enhanced enlargement of the
the Brava external breast expander.
