Reduction mammoplasty (also breast reduction and reduction mammaplasty) is the
plastic surgery procedure for reducing the size of large breasts. In a breast reduction surgery for re-establishing a functional
bust that is proportionate to the patient's body, the critical corrective consideration is the
tissue viability of the
nipple–areola complex (NAC), to ensure the functional sensitivity and

, or by a combination of both occurrences of hypertrophy. The resultant breast-volume increases can range from the mild (<300 gm) to the moderate (ca. 300–800 gm) to the severe (>800 gm). Macromastia can be manifested either as a unilateral condition or as a bilateral condition (single-breasted enlargement or double-breasted enlargement) that can occur in combination with sagging,
breast ptosis that is determined by the degree to which the nipple has descended below the inframammary fold (IMF).
Therapeutic approaches
Medical
Breast hypertrophy (macromastia and gigantomastia) does not respond to medical therapy, but a weight-reduction regimen for the certain patients can alleviate some of the excessive size and volume of abnormally enlarged breasts.
Physical therapy provides some relief for neck, back, or shoulder pain. Skin care will diminish breast crease inflammation and lessen the symptoms caused by moisture, such as irritation, chafing, infection, and bleeding.
Surgical
The traditional surgical techniques for breast reduction remodel the breast mound using a skin and glandular (breast tissue) pedicle (inferior, superior, central), and then trim and re-drape the skin envelope into a new breast of natural size, shape, and contour; it produces long surgical scars upon the breast hemisphere. In response, L. Benelli, in 1990, presented the round block mammoplasty, a minimal-scar periareolar incision technique that produces only a periareolar scar – around the NAC, where the dark-to-light skin-color transition hides the surgical scar.

Composition
Surgically, the breast is an
apocrine gland overlaying the chest – attached at the nipple and suspended with ligaments from the chest – which is integral to the skin, the
body integument of the individual. The dimensions and weight of the breasts vary with age and habitus (body build and physical constitution); hence, small-to-medium-sized breasts weigh approximately 500 gm, or less, and large breasts weigh approximately 750–1,000 gm. Anatomically, the
breast topography and the hemispheric locale of the NAC are particular to each individual; thus, the desirable, average measurements are a 21–23 cm sternal distance (nipple to sternum-bone notch), and a 5–7 cm inferior-limb distance (NAC to IMF).

Mechanical structures of the breast
In realizing the breast-reduction corrections, the plastic surgeon takes

# Fatty tissue. In biology, adipose tissue (/ˈædəˌpoʊs/), or body fat, fat depot, or just fat, is loose connective tissue composed of adipocytes. It is technically composed of roughly only 80% fat; fat in its solitary state exists in the liver and muscles. Adipose tissue is derived from lipoblasts. Its main role is to store energy in the form of lipids, although it also cushions and insulates the body. Far from hormonally inert, adipose tissue has in recent years been recognized as a major endocrine organ
as it produces hormones such as leptin, resistin, and the cytokine TNFα. Moreover, adipose tissue can affect other organ systems of the body and may lead to disease. Obesity or being overweight in humans and most animals does not depend on body weight but on the amount of body fat – to be specific, adipose tissue. Two types of adipose tissue exist: white adipose tissue (WAT) and brown adipose tissue (BAT). The formation of adipose tissue appears to be controlled in part by the adipose gene. Adipose tissue was first identified by the Swiss naturalist Conrad Gessner in 1551.

Surgical procedures
General
Reduction mammoplasty, either surgery or lipectomy, proportionately re-sizes the enlarged, sagging breasts of a patient affected with macromastia (>500 gm increase per breast) or with gigantomastia (>1,000 gm increase per breast). Breast reduction surgery has two technical aspects: (i) the skin-incision pattern and the skin- and glandular-tissue excision technique applied for access to and removal of breast

The incision pattern and the area of skin-envelope tissue to be removed determine the locales and the lengths of the surgical scars; (ii) the final shape and contour of the reduced breast are determined by the area of the tissues remaining in the breast, and that the skin- and glandular-tissue pedicle has a proper supply of
nerves and blood vessels (

The full, corrective outcome of the surgical re-establishment of a bodily proportionate bust becomes evident at 6-months to 1-year post-operative, during which period the reduced and lifted breast tissues settle upon and into the chest.

al capability and function.
The volume and size reduction of
hypertrophied breasts is performed with a periareolar incision to the NAC, which then extends downwards, following the natural curve of the breast hemisphere. After cutting and removing the requisite quantities of tissue (glandular, adipose, skin), the NAC is transposed higher upon the breast hemisphere; thereby, the inferior pedicle technique produces an elevated bust with breasts that are proportionate to the patients's person. Breast-reduction with an inferior pedicle occasionally produces breasts that appear squared; despite this, the technique effectively reduces the very enlarged breasts of macromastia and gigantomastia.
II. Vertical scar technique (lollipop incision)
The breast reduction performed with the vertical-scar technique usually produces a well-projected bust featuring breasts with short incision

s and a NAC elevated by means of a pedicle (superior, medial, lateral) that maintains the
biologic and
functional viability of the NAC. The increased projection of the reduced bust is achieved by medially gathering the folds of the skin-envelope and suturing the inner and outer portions of the remaining breast gland to provide a support pillar, and upward projection of the NAC . The vertical-scar reduction mammoplasty is best suited for removing small areas of the skin envelope and small volumes of internal tissues (glandular, adipose) from the lateral and the inferior portions of the breast hemisphere; thus the short incision scars.
III. Horizontal scar technique
The breast reduction performed with the horizontal-scar technique features a horizontal incision along the inframammary fold (IMF) and a NAC pedicle. To elevate the NAC, the technique usually employs either an inferior pedicle or an inferior-lateral pedicle, and features no vertical incision (like the anchor pattern). The horizontal-scar technique best applies to the patient whose oversized breasts are too large for a vertical-incision technique (e.g. the lollipop pattern); and it has two therapeutic advantages: no vertical incision-scar to the breast hemisphere, and better healing of the periareolar scar of the transposed NAC. The potential disadvantages are box-shaped breasts with thick (hypertrophied) incision scars, especially at the inframammary fold.

Surgical techniques
Pre-operative matters
The
medical treatment records for the reduction mammoplasty are established with pre-operative, multi-perspective photographs of the oversized breasts, the sternal-notch–to-nipple distances, and the nipple-to–inframammary-fold distances. The patient is instructed about the purposes of the breast reduction surgery; the achievable corrections; the expected final size, shape, and contour of the reduced breasts; the expected final appearance of the breast reduction

s; possible changes in the sensation of the
NAC; possible changes in
breast-feeding capability; and possible
medical complications. The patient also is instructed about post-operative matters, such as convalescence, and the proper care of the surgical wounds to the breasts.
Incision-plan delineation: to the breasts of the standing patient, the plastic surgeon delineates the mosque dome skin-incision plan, and the area representing the superior pedicle (composed of skin and glandular tissues), the breast midline, the inframammary fold (IMF), and the vertical axis of the breast, beneath the IMF. The upper edge of the (future) NAC is marked slightly below the IMF-level, and a semicircle of 16-cm maximum diameter. In relation to the vertical axis, the mosque dome incision plan displaces the breast to the middle and to the side; the peripheral limbs of the incision plan are marked so that they approximate (join) at no less than 5-cm above the inframammary fold. The circumference of the (future) NAC is delineated around the nipple, and a superior pedicle (10-cm wide minimum) is delineated at the upper-border of the future NAC circumference; the incision-plan delineation continues down as a cone, and around the marked circumference.
Operative technique
The patient is laid supine upon the operating table so that the surgeon can later raise them to a sitting position that will allow visual comparison of the drape of the breasts, and an accurate assessment of the post-operative symmetry of the reduced and lifted bust. Afterwards, the pedicle epidermis surrounding the NAC is cut, and adipose tissue is liposuctioned from the breast. The medial, lower, and lateral segments of the breast are resected (cut and removed), by undermining the skin below the lower curved line. Then, the NAC is transposed higher upon the breast hemisphere. The pillars of
parenchymal tissue are approximated (joined), and the skin envelope is sutured.
There is no evidence to support using drains during breast reduction surgery.

foci occur in 0.1–0.9 per cent of the tissue specimens.
* Technical: The original Lejour technique incision plan had no horizontal limbs, and so did not produce horizontal scars; however, contemporary variants, such as the Modified Lejour Technique, employ small, horizontal incisions along the inframammary fold, in order to avoid redundant skin folds, especially in the reduction of very oversized breasts.
Post-operative matters
The patient is instructed to resume normal life activities, and to eat a light diet, post-operative, on the day of the breast reduction surgery; to resume washing in a shower at 1-day post-operative; to avoid strenuous physical activity, and to wear a sports brassière; the convalescence regimen is for three-months post-operative. The patient is also informed that the wrinkles at the bottom of the vertical limb of the scar usually resolve and fade within one–six months post-operative, but some cases may require surgical revision of the vertical scar. Scheduled follow-up consultations ensure a satisfactory outcome to the breast reduction surgery, and facilitate the early identification and management of medical complications.
Limited evidence shows no significant benefit in the use of wound drains after reduction mammoplasty.

Nonetheless, bottom-edge asymmetry occurs more among Lejour-technique patients; the revision surgery rates can be up to 10 percent. Moreover, the liposuctioning of the breast does not increase the rate of local medical complications; decreased NAC sensitivity occurs in 10 percent of patients, and total NAC insensitivity occurs in 1.0 per cent of women.

is a reliable reduction mammoplasty procedure, which yields consistent results of size, appearance, and texture of the reduced-volume breasts. The second study by Daniel Lanzer, ''Breast Reduction with Liposuction'' (2002), about a 250-patient cohort, reported that the application of tumescent liposuction, as the sole reduction-mammoplasty procedure, yielded consistent results wherein none of the patients had loose breast-skin envelopes, irregular breast-shape, permanent loss of sensation (either glandular, dermal, or of the NAC), scars, tissue necrosis

generally returned to the same level as before treatment, despite maintaining the previous diet and exercise regimen. While the fat returned somewhat to the treated area, most of the increased fat occurred in the abdominal area. Visceral fat - the fat surrounding the internal organs - increased, and this condition has been linked to life-shortening diseases such as diabetes, stroke, and heart attack.
Indications
The reduction of oversized breasts by liposuction only (lipectomy) is indicated when a minor-to-moderate volume-reduction is required, and there is no breast ptosis to correct. However, in a 2001 study of 250 patients, nipple and breast elevation of between 3 cm and 15 cm was reported. Further indications for lipectomy are presented by: (i) the patient who requires a large-volume reduction, and wants un-scarred, sensate breasts, but will accept a degree of ptosis; (ii) the patient who requires a secondary mammoplasty to correct an asymmetric breast, by up to one brassière cup-size; and (iii) the patient affected by juvenile breast hypertrophy, as a temporary procedure performed before the conclusion of thelarche

Contraindications
Breast reduction by liposuction only cannot be performed upon a patient whose mammogram

The patient is further informed of the possible medical complications, and is shown surgical photographic records of the average outcomes of breast-reduction surgery. The surgeon answers the patient's questions to assist in establishing realistic expectations (self-image

) about the breast-reduction outcome possible with a lipectomy procedure; and that, should lipectomy not satisfactorily reduce the breast volume, a secondary, surgical breast-reduction procedure can be performed later.
The measures of the bust: a liposuction mammoplasty procedure does not feature a surgical-incision plan delineated upon the patient's breasts, chest, and torso, but the measures of the bust are established in order to determine the required degree(s) of correction; thus, with the patient sitting erect, for each breast, the surgeon records the jugular-notch-to-nipple distances, the nipple-to-inframammary-fold distances, and any asymmetries. Afterwards, the anaesthetized patient is laid supine upon the operating table, arms laterally extended (abducted), in order to fully expose the breasts.
Anaesthestic preparation: to limit bleeding during the liposuction, the proper degree of vasoconstriction of the breast's circulatory system is established with an anaesthetic

, the anaesthetic infiltration begins at the deep plane of the breast, and continues as the cannula is withdrawn towards the superficial plane of the breast. The entire area of the breast is infiltrated with the anaesthetic solution until the tissues become tumescent (firm). Moreover, as required by the patient's physique, an intravenous (IV) pressure bag can be applied to hasten the infiltration; after the anaesthetic has numbed the breast, the plastic surgeon begins the lipectomy breast-reduction.
Operative technique
The surgeon effects a stab incision just above the lateral aspect of the inframammary fold (IMF), piercing the skin 2-cm above the inframammary fold, in the midline. The pre-tunnelling is performed with the blunt-tip, multi-perforation cannula used to infiltrate the anaesthetic

solution to the breast tissues. A blunt-tip, 4-mm cannula, connected either to a medical-grade vacuum pump or to a syringe, is used to aspirate the adipose fat. The cannula is maneuvered laterally (in fanning movements), beginning in the deep plane of the breast and concluding in the superficial plane of the breast; the adipose fat sucked from the breast is a yellow, fatty, bloodless fluid; the liposuction concludes upon drawing the required volume of fat, or when the fat becomes bloody.
After the liposuction, the superficial layer of adipose fat is undermined with a blunt-tip, 3-mm cannula (which is not connected to a vacuum pump). The breast ptosis is corrected by stimulating the controlled retraction of the incision scar, by undermining the superficial fat of the medial and the lateral upper areas of the breast; the maneuver tightens (retracts) the skin envelope of the breast. Procedurally, the liposuction-only breast reduction procedure concludes with the application of an elastic, foam-tape dressing that molds the reduced breast into its new shape, and lifts it higher upon the chest.
Technical note: for the reduction of very enlarged breasts, the plastic surgeon makes a supplementary incision just above the medial aspect of the inframammary fold. Procedurally, the placement of this incision later allows converting the lipectomy breast-reduction procedure into an inferior-pedicle breast reduction surgery, if liposuction proved inadequate to satisfactorily reducing the volume of the very enlarged breasts.
Post-operative matters
Convalescence
The patient is discharged from hospital either the same day or the day after the breast reduction operation. Because the liposuction-only procedure featured only a few, small, surgical incisions, the patient quickly recovers their health, usually resuming daily life activities at 14 to 28 days post-operative – when the breast-molding dressings are changed; the patient also resumes their personal hygiene regimen, to include washing under a water shower. In the initial convalescence period, the surgical-incision wounds are inspected at 1-week post-operative, during which time the patient has continuously worn a strapless brassière to contain and immobilize the corrected breasts; afterwards, the patient continuously wears a strapped brassière for 30 days after the breast-reduction operation.
