Abstract
Unfortunately, many women after a breast reduction resemble candidates for an augmentation mastopexy because the Wise pattern can leave breasts looking deflated and boxy. A vertical reduction provides a modest boost in breast projection and upper pole projection, and tighter, more circular lower poles than a Wise pattern. Patients prefer the aesthetic result and scars of the vertical technique. In patients who wish to restore upper pole volume, breast implants are most effective.
Originally, a breast reduction was considered a purely functional procedure. Today, expectations are higher and include aesthetic considerations. Numerous studies document the physical benefits of a breast reduction. Fewer publications evaluate the patient’s perception of the aesthetic result. Patients readily understand that the goal is still to make their breasts smaller and relieve symptoms. Breast implants can help to restore a more ideal shape to a breast that has been distorted by hypertrophy and gravity.
The surgical approach for a breast reduction plus implants is the same as for an augmentation mastopexy. The procedures are arbitrarily differentiated only by the weight of breast tissue removed (≥300 g from 1 breast). A vertical mammaplasty is performed using a medially based pedicle and intraoperative nipple siting. Breast implants are inserted subpectorally. An inverted-T modification is used when the vertical scar extends below the level of the new inframammary fold.
Upper pole projection is increased approximately 2 cm when implants are used, compared with <1 cm for women who do not have implants. The most common complication is delayed wound healing (25%). After surgery, symptoms of back, shoulder, or neck pain are reported by only 21% of women undergoing breast reduction alone versus 19% of women who also receive implants (difference nonsignificant). The data suggest that implants do not undermine the functional benefit of reduction mammaplasty.

This observation is especially true after a Wise pattern inferior pedicle reduction, which typically leaves the breasts looking deflated and boxy [11]. Measurements confirm that an inverted-T (Wise pattern), inferior pedicle mammaplasty does not improve breast projection or upper pole projection [2]. A vertical reduction mammaplasty provides a modest boost in breast projection and upper pole projection (<1 cm), and tighter, more circular lower poles than a Wise pattern [2]. In patients who wish to restore upper pole volume, breast implants are most effective [3]. The author uses the term “breast reduction plus implants” [1, 3] to label this combination, avoiding the possibly confusing term “augmentation reduction.”

Combining breast reduction and implants might strike some surgeons as contradictory and even unethical [4]. A growing number of plastic surgeons, however, believe that this combination has a proper place in the plastic surgeon’s armamentarium [5]. To learn more about this procedural combination, the author undertook a study to determine its efficacy and safety, and to compare breast measurements and patient-reported outcomes in breast reduction patients treated with and without implants [6]. A breast reduction was defined as removal of ≥300 g of breast tissue from at least one breast [3].
All patients were treated by the same surgeon, at the same facility, using the same operation, and imaged using standardized methods. These factors avoid confounding influences and increase the reliability of the conclusions. For example, if different surgeons treat patients with different operations (a common practice is to use the vertical technique for moderate reductions and a Wise pattern for large ones) [7], it is impossible to exclude the influence of the surgeon and technique. Only by holding these variables constant is it possible to isolate the effect of implants on the surgical result.
It might seem that resecting approximately 369 g of breast tissue and adding approximately 334 cc of volume in the form of an implant (these are the average values from the study) [6] would produce a result similar to a small (i.e., 35 g) mastopexy. However, this is not the case because such a calculation does not take into account the profound changes in proportions of the upper and lower poles, which tend to cancel out when added together. Figure 8.2 depicts such a patient. The morphological changes after a small-volume mastopexy are much less pronounced [3].

This 23-year-old was aware of her asymmetry. She wanted to feel comfortable wearing a bikini. She is seen before (left) and 3 months after (right) a breast reduction plus implants. The same implant size was used for both breasts, a smooth, round moderate plus profile 240 cc saline implant (Mentor Corp.). The resection weights were 466 g on the right side and 314 g on the left side
Function and Appearance
Originally, a breast reduction was considered a functional procedure, meant to reduce breast mass and elevate the nipple position. These goals were achieved by the 1920s [8–10]. Today, expectations are higher and include aesthetic considerations [11]. Patients having breast reduction are concerned about their symptoms, but the majority quite understandably wish to improve their breast appearance as well [11]. Numerous studies document the physical benefits of a breast reduction [11]. Fewer publications evaluate the patient’s perception of the aesthetic result [11]. Patients consistently prefer the aesthetic result and scars of the vertical technique [12–15]. Surgeons [16–18] are aware of the flattening, boxiness, and bottoming-out that can be apparent after breast reduction. These observations have been confirmed with measurements [2, 19].
Surgery
The surgical approach for a breast reduction plus implants is the same as for an augmentation mastopexy. The procedures are arbitrarily differentiated only by the weight of breast tissue removed. A vertical mammaplasty is performed using a medially based pedicle [16] and intraoperative nipple siting [1–3]. A mosque-dome or keyhole preoperative pattern is not used. Breast implants are inserted subpectorally, although some surgeons may prefer a prepectoral plane. A vertical resection is performed (Fig. 8.3). The nipple/areola site is determined after creation of the new breast mound. An inverted-T modification is used in patients in whom the vertical scar extends below the level of the new inframammary fold (Fig. 8.3).

This patient’s inframammary fold was raised approximately 2.5 cm by the vertical mammaplasty, leaving the inferior portion of the wound below the level of the new inframammary fold (below, left). Accordingly, the inferior dog ear is revised using a short inverted-T modification so as not to be visible below the crease (below, center). She is seen after skin closure (below, right)
Surgery is performed on outpatients in a state-licensed ambulatory surgery center using total “SAFE” (spontaneous breathing, avoid gas, face up, extremities mobile) intravenous anesthesia [20]. No muscle relaxation is used so as to preserve the calf muscle pump [21]. Patients are also monitored for venous thromboembolism using ultrasound surveillance as part of a clinical trial in progress [22]. The mean operating time for a vertical breast reduction is 2 h [6]. Simultaneous implant insertion adds only 18 min of operating time , on average [6]. The same synergistic advantages for augmentation mastopexy (compared with either operation performed individually) are available for this combination [1]. Videos demonstrating this combined procedure are available at the Plastic and Reconstructive Surgery Global Open website: http://journals.lww.com/prsgo/Pages/videogallery.aspx?videoId=23&autoPlay=true. The videos include preoperative marking, details of the surgery and anesthesia, and follow-up 24 h after surgery.
Measurements
Breast area, measured on lateral photographs (a surrogate for volume), decreases despite the use of implants [6]. Not surprisingly, the upper pole area is increased to a greater extent than in women who do not receive implants. A vertical breast reduction increases breast projection and upper pole projection even without implants. However, upper pole projection is increased approximately 2 cm when implants are used, compared with <1 cm for women who do not have implants [6].
Upper pole projection is increased approximately 2 cm when implants are used, compared with <1 cm for women who do not have implants.
A vertical reduction, with or without implants, reduces the lower pole area and elevates the lower pole level, reflecting the fact that the lower pole resection is the same regardless of whether implants are used [6]. The lower pole ratio is defined as the lower pole width divided by lower pole length (height) and is an indicator of the boxiness of the lower poles [23]. Values exceeding 2.0 start to appear boxy; values <2.0 appear conical. The overall mean lower pole ratio after a vertical breast reduction is 2.0 cm, with or without implants [6].
