It is a great pleasure and privilege to recommend this book on breast augmentation, having spent over 25 years of my life dealing with and operating on breasts. It is still fascinating to understand why breast augmentation has become one of the most com-mon cosmetic operations in the world. The psychology and body image that influence a woman’s decision to have this operation are still a mystery. Many books and articles have been written about various techniques; however, you will find all of this condensed in this book, with the latest information and research to help you understand this rela-tively simple operation. Varying approaches and different implants have puzzled many surgeons and patients alike, and this book provides enlightenment.

Implants and materials used in this operation are discussed and argued in this book and settle the score on which implant should be used in the 21st century. The position-ing of the implants either above or below the muscle is discussed in detail, and the rea-sons behind the authors’ preferences are well demonstrated. Capsule formation has been considered as a sequela of the operation, and many speculations have been put forward as to the likely cause. However, to date, no surgeon or theory has convinced me that the answer has been found as to the likely cause of this condition, and that is why the treat-ment has been toward symptomatic management rather than prevention and cure.

The size of the implants and the final result have depended mostly on the surgeon’s experience and the patient’s psychological state. There is no precise way to accurately determine the size; however, my measurements and ideas have been put forward to help both novice and experienced surgeons alike. New ideas and measurements have also been put forward. Indications and information on where to draw the line between aug-mentation and mastopexy and when to combine the two operations are discussed.

The purpose of this book is to discuss the current thoughts and trends in breast aug-mentation and to detail the current techniques used, as well as to discuss various com-mon complications of this procedure, how to deal with these problems, and how to treat these conditions using the current thoughts and tried and tested methods.

A unique contribution to the gratification of these human needs has been the de-velopment of surgical techniques that are safe, reasonable, and available. These are de-scribed in this book and seem to answer many questions, based on scientific and sound anatomical bases.

Breast augmentation is one of the most common cosmetic procedures performed. Women who are concerned about the size of their breasts will seek an improved appear-ance with augmentation to conform to their own body image. Despite the prolonged litigation and settlement of lawsuits concerning silicone breast implants and their pos-sible association with autoimmune disease, there has been a resurgence in the frequency of breast augmentation. It has ultimately been shown that silicone is not the cause of the claimed autoimmune disease. Additionally, introduction of a cohesive gel implant that does not contain silicone gel fluid that can “bleed” into the pocket has contributed to a decrease in capsule contracture.

Surgeons performing breast augmentation have to be well informed, not only about the variety of techniques that are available but also about the possible risks and compli-cations of the procedure. The surgeon should be capable of deciding which procedure to use to correct any defect or deformity and of avoiding or treating the variety of possible complications of the surgery. The patient should understand that the possibility exists for a second or even third procedure on the breast after augmentation.

This book is an attempt to bring together, as much as possible, augmentation surgery techniques, the possible complications of each one, and the means of correcting breast imperfections. It also includes chapters on embryology, anatomy, benign and malig-nant breast diseases, mammograms, body dysmorphic disorder, implant choice, breast augmentation principles, the various pockets and incisions, and medical-legal aspects. The international contributors are experts in the field of breast augmentation and have helped put together a much needed textbook to cover the varieties of breast problems and their solutions.

Chapter

1.1 Introduction

In the middle and fore-part of each side of the Chest, there rise two fleshy Eminences, called the Breasts, which are a good deal larger in Women than in Men. The Breasts of Women are composed of Glandular Bod-ies, interspersed with an infinite Number of Vessels, which serve for the Secretion of Milk. Those of Men are only composed of Skin, Flesh, and Fat … In general, the Breasts of Men ought to be small, and a little plain. Those of Women ought to be round, high, and have the Figure of two Hemispheres, separated from one another by a middle Interstice.Nicolas Andry de Bois-Regard, Orthopaedia (1743) [1]

1.2 Embryogenesis

The ectoderm and the mesenchyme are responsible for the genesis of the male and female breast. The ectoderm is responsible for the formation of the ducts and alveoli, and the mesenchyme is responsible for the connective tissue and its vessels.

In the ventral area of the body, the milk line (ridge) develops (Fig. 1.1). Usually, it extends from the axilla to the inguinal area. However, occasionally the milk ridge extends down into the triangle of Scarpa. The pectoral part of the milk ridge produces the right and left mam-mary primordia. The proximal and distal part of the ex-trapectoral ridge disappears.

Kopans [2] stated that the breasts have the same ecto-dermal origin as skin glands (Fig. 1.2). The ectodermal thickening of the mammary primordium grows into the dermis [3]. This produces 16–24 solid cords of ecto-dermal cells growing within the underlying mesoderm (dermis). Later, these buds will become canalized and form the lactiferous ducts and alveoli. The epidermal surface of the future nipple is at first a shallow depres-sion during the final trimester; near term it becomes everted and ready to accept the lactiferous ducts.

Howard and Gusterson [4] stated that very little is known about the molecular mechanisms that initiate breast formation. A small part of the ridges remains in

the pectoral area, which is responsible for the genesis of the right and left breasts as well as for the embryological mammary anomalies. The typical developmental har-mony between ectoderm (epithelial ductal lining and acini) and mesenchyme (the skin and the supporting elements) occasionally goes awry, producing congenital anomalies of the breast.

Each mammary lobe has one lactiferous duct, which terminates at the nipple of the mammary gland. The pathway of the lobes is from the nipple to the connective and fatty tissue of the superficial fascia. Thus, the breast can be conceptualized as a grouping of large glands that originate from the epidermis. Langebartel [5] termed

1Embryology and Anatomy of the BreastJohn E. Skandalakis

Page 27: Melvin A. Shiffman (Editor)€¦ · anatomical bases. Anthony Erian Foreword. ... Despite the prolonged litigation and settlement of lawsuits concerning silicone breast implants and

the female breast “mostly a mound of fat, with fascias and fibrous strands and the mammary gland (active or inactive).”

Kopans [2] analyzed breast development: “The breast develops in the superficial layer of fascia that lies just beneath the skin. It is not clear whether the superficial layer splits into a deep and superficial layer to form an incomplete envelope around the gland, or whether the elongating ducts invaginate the fascia, which then ends up enveloping the gland” (Fig 1.3).

The chronology of breast development is presented in Table 1.1.

The breast characteristically presents changes when still in utero as well as during the extrauterine period. Russo and Russo [6] divide these changes into two phases:• Developmental phase: Early stages of gland morpho-

genesis from nipple epithelium to lobule formation• Differentiation phase: Differentiation of mammary

epithelium

Remember: The ridges disappear early, but a small por-tion remains in the pectoral region. This is responsible for the genesis of “a single pair of glands,” according to Bland and Romrell [7].

Neville et al. [8, 9] have summarized the stages of hu-man mammary development (Table 1.2), noting the role of the mammary fat pad in the development of the mam-mary epithelium. The fat pad provides signals that me-diate ductal morphogenesis and alveolar differentiation.

The genesis of the breast is an enigma. Sakakura [10] and Robinson et al. [11] have discussed mesenchymal interactions.

1.3 Congenital Anomalies

The axilla is the most common area in which accessory breast tissue can be found [2]. The multiple but rare congenital anomalies of the breast may be associated with various other syndromes. It is not within the scope of this chapter to study these syndromes or their associ-ated anomalies.

1.3.1 Amastia

By definition, amastia is the absence of one or both breasts. This congenital phenomenon is very rare. The first reports of unilateral amastia [12], bilateral amastia

Fig. 1.3 It is unclear how the breast devel-ops with respect to the superficial fascia, which runs just under the skin. a The fascia may split, forming a deep and superficial layer with the breast in between (insinua-tion). b–d The other possibility is that as the ducts elongate and grow back into the soft tissues, they may be enveloped by the fascia (invagination; e, f).

[13], and amastia (with or without athelia) associated with Poland syndrome [14] were all published in the 1800s. In 1917, Deaver and McFarland [15] reported other congenital anomalies in association with amastia.

In females, unilateral breast absence is the most common form of amastia. Bilateral amastia has been reported in male and female patients [16].

Trier [17] divided his presentation of 43 cases of amastia into three categories:

• Bilateral amastia • Unilateral amastia• Bilateral amastia with congenital ectodermal defects According to Merlob [18], 40% of all cases of amastia are associated with other congenital malformations (skeletal, facial, renal, genital). Several syndromes are associated with this condition [19–22]. Familial oc-currence has been observed by various investigators

[23–24], and complete absence of a breast in siblings has been reported [25].

Greydanus and colleagues [26] state that amastia is the result of “complete mammary ridge involution, in-cluding the pectoral ridge on the affected side.”

1.3.2 Athelia

Athelia, from the Greek word ΘΗΛΗ, is the congenital absence of one or both nipples and areolas of the breast. Athelia, which may be the rarest of all breast anoma-lies [27], may result from a developmental failure of the lower cervical and upper thoracic somites [28]. The fatty stroma is the precursor of the mammary fat pad [29], and without a good stroma, the overlying breast tissue cannot grow.

Ishida et al. [29] reported that athelia “is always asso-ciated with other anomalies… but [is] usually associated with amastia.” These authors stated that “individuals

generally present absence of the nipple–areola complex inside a constellation of other alteration. So, athelia can-not be classified in distinct groups.” Latham et al. [30] cautioned that athelia, which is “uniformly described in the literature as being associated with a syndrome or a cluster of syndromes,” should be differentiated from amastia (absence of breast tissue and nipple–areolar complex) and amazia (absence of breast tissue).

The inverted nipple is not an athelic phenomenon. According to Lawrence and Lawrence [28], it is the re-sult of the persistence of fibers from the original invagi-nation of the mammary pit (dimple).

1.3.3 Polythelia

More than two nipples, each with an areola, are present in polythelia. Schmidt [31] stated, “Not every supernu-merary areola has a nipple, but every supernumerary nipple has an areola. The term ‘polythelia’ means a de-

veloped areola with a nipple.” Supernumerary nipples may be found anywhere along the embryonic milk line [32]. Merlob [18] reported the prevalence of supernu-merary nipples in various ethnic population studies as ranging from 0.22% to 11–16%. He stated that polythe-lia may be sporadic, familial, or syndromic.

Table 1.3 presents congenital malformations and dis-eases associated with polythelia.

1.3.4 Polymastia

The presence of more than two breasts, which are usu-ally located at the mammary ridge, is called polymastia. The terms “ectopic breast” and “supernumerary breast” also appear in the literature. Darwin [33] viewed both polymastia and polythelia as atavistic traits, represent-ing human phylogeny.

Supernumerary breasts and nipples have a 1–2% in-cidence of all live births [7, 34].

What embryogenetic explanation can be found for the reported cases of supernumerary mammary organs on the vulva, legs, or dorsal trunk? Dixon and Mansel [35] stated that the cause is unknown. Ectopic and nor-mally located breasts may be equally subject to pathol-ogy (mastitis, cancer, etc.).

Polymastia is associated with other anomalies, both obvious and more hidden. Mehes and colleagues [36–38] and Goeminne [39] advise complete evaluation of the patient with ectopic breast(s) to rule out other prob-lems, such as renal anomalies.

1.3.5 Breast Asymmetry

Araco et al. [40] defined breast asymmetry as “an asym-metric morphology of the shape, volume, or position of the breast, the nipple–areola complex, or both.” Tu-

berous breast deformity (an aberration of breast shape) includes a spectrum of symmetrical and asymmetrical defects, both unilateral and bilateral [41].

In megalomastia, the breast is extremely enlarged. Unilateral megalomastia is extremely rare [42].

Micromastia is a congenital condition in which the breast fails to develop beyond its prepubertal state, de-spite the presence of mammary gland tissue [27]. The condition may be unilateral or bilateral. The etiology of micromastia (hypoplasia, aplasia) is unknown; however, unilateral hypoplasia may be associated with several syndromes, such as congenital renal hyperplasia and other autosomal dominant inherited conditions.

1.3.6 Gynecomastia

Gynecomastia refers to enlargement of the male breast. The development and then spontaneous regression of mild gynecomastia is common and usually asymptom-atic in young men. Gynecomastia is also relatively com-mon in older men; it is usually idiopathic and commonly regresses spontaneously [3].

1.4 Anatomy

The female breast is practically enveloped by the su-perficial fascia of the anterior chest wall (Fig 1.4). The superficial fascia is continuous with the superficial abdominal fascia of Camper below and the superficial fascia of the neck above, merging anteriorly with the dermis of the skin.

The base of the breast has the following extensions:• From the 2nd rib (above) to the 6th or 7th rib (be-

low)• From the sternal border (medial) to the midaxillary

line (lateral)
