Mastopexy
Mastopexy (Greek μαστός ''mastos'' "breast" + -pēxiā "affix") is the plastic surgery mammoplasty procedure for raising sagging breasts upon the chest of the woman, by changing and modifying the size, contour, and elevation of the breasts. In a breast-lift surgery to re-establish an aesthetically proportionate bust for the woman, the critical corrective consideration is the tissue viability of the nipple-areola complex (NAC), to ensure the functional sensitivity of the breasts for lactation and breast-feeding. The breast-lift correction of a sagging bust is a surgical operation that cuts and removes excess tissues (glandular, adipose, skin), overstretched suspensory ligaments, excess skin from the skin-envelope, and transposes the nipple-areola complex higher upon the breast hemisphere. In surgical practice, mastopexy can be performed as a discrete breast-lift procedure, and as a subordinate surgery within a combined mastopexy–breast augmentation procedure. Moreover, ...

Ptosis (breasts)
Ptosis or sagging of the female breast is a natural consequence of aging. The rate at which a woman's breasts drop and the degree of ptosis depends on many factors. The key factors influencing breast ptosis over a woman's lifetime are cigarette smoking, her number of pregnancies, higher body mass index, larger bra cup size, and significant weight change. Post-menopausal women or people with collagen deficiencies (such as Ehlers-Danlos) may experience increased ptosis due to a loss of skin elasticity. Many women and medical professionals mistakenly believe that breastfeeding increases sagging. It is also commonly believed that the breast itself offers insufficient support and that wearing a bra prevents sagging, which has not been found to be true. Plastic surgeons categorize the degree of ptosis by evaluating the position of the nipple relative to the infra-mammary fold, the point at which the underside of the breasts attach to the chest wall. In the most advanced stage, the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breast Reduction
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 woman's body, the critical corrective consideration is the tissue viability of the nipple–areola complex (NAC), to ensure the functional sensitivity and lactational capability of the breasts. The indications for breast reduction surgery are three-fold – physical, aesthetic, and psychological – the restoration of the bust, of the woman's self-image, and of her mental health. In corrective practice, the surgical techniques and praxis for reduction mammoplasty also are applied to mastopexy (breast lift). Presentation The woman with macromastia presents heavy, enlarged breasts that sag and cause her chronic pains to the head, neck, shoulders, and back; an oversized bust also causes her secondary health problems, such as poor blood circula ...

Mammoplasty
Mammaplasty (also called mammoplasty or mastoplasty) refers to a group of surgical procedures, the goal of which is to reshape or otherwise modify the appearance of the breast. There are two main types of mammoplasty: # Augmentation mammaplasty is commonly performed to increase the size, change the shape, and/or alter the texture of the breasts. This usually involves the surgical implantation of breast implant devices. # Reduction mammaplasty is commonly performed to reduce the size, change the shape, and/or alter the texture of the breasts. This involves the removal of breast tissue. Social context Mammaplasty started out a surgical procedure to help relieve women of the excess weight of their breasts, it was only later that it was used for cosmetic purposes. There is immense pressure on women to subscribe to socially prescribed beauty standards of how their bodies must be, a part of this is the pressure on women to have 'perfect breasts'. Earlier records of such surgery wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breast Anatomy Normal Scheme
The breast is one of two prominences located on the upper ventral region of a primate's torso. Both females and males develop breasts from the same embryology, embryological tissues. In females, it serves as the mammary gland, which produces and secretes milk to feed infants. Subcutaneous fat covers and envelops a network of lactiferous duct, ducts that converge on the nipple, and these tissue (biology), tissues give the breast its size and shape. At the ends of the ducts are mammary lobule, lobules, or clusters of mammary alveolus, alveoli, where milk is produced and stored in response to hormone, hormonal signals. During pregnancy, the breast responds to a complex interaction of hormones, including estrogens, progesterone, and prolactin, that mediate the completion of its development, namely lobuloalveolar maturation, in preparation of lactation and breastfeeding. Humans are the only animals with permanent breasts. At puberty, estrogens, in conjunction with growth hormon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superficial Anatomy
Surface anatomy (also called superficial anatomy and visual anatomy) is the study of the external features of the body of an animal.Seeley (2003) chap.1 p.2 In birds this is termed ''topography''. Surface anatomy deals with anatomical features that can be studied by sight, without dissection. As such, it is a branch of gross anatomy, along with endoscopic and radiological anatomy.Standring (2008) ''Introduction'', ''Anatomical nomenclature'', p.2 Surface anatomy is a descriptive science. In particular, in the case of human surface anatomy, these are the form and proportions of the human body and the surface landmarks which correspond to deeper structures hidden from view, both in static pose and in motion. In addition, the science of surface anatomy includes the theories and systems of body proportions and related artistic canons. The study of surface anatomy is the basis for depicting the human body in classical art. Some pseudo-sciences such as physiognomy, phrenology and pa ...

Integumentary System
The integumentary system is the set of organs forming the outermost layer of an animal's body. It comprises the skin and its appendages, which act as a physical barrier between the external environment and the internal environment that it serves to protect and maintain the body of the animal. Mainly it is the body's outer skin. The integumentary system includes hair, scales, feathers, hooves, and nails. It has a variety of additional functions: it may serve to maintain water balance, protect the deeper tissues, excrete wastes, and regulate body temperature, and is the attachment site for sensory receptors which detect pain, sensation, pressure, and temperature. Structure Skin The skin is one of the largest organs of the body. In humans, it accounts for about 12 to 15 percent of total body weight and covers 1.5 to 2 m2 of surface area. The skin (integument) is a composite organ, made up of at least two major layers of tissue: the epidermis and the dermis. The epidermis is ...

Nipple
The nipple is a raised region of tissue on the surface of the breast from which, in females, milk leaves the breast through the lactiferous ducts to feed an infant. The milk can flow through the nipple passively or it can be ejected by smooth muscle contractions that occur along with the ductal system. The nipple is surrounded by the areola, which is often a darker colour than the surrounding skin. A nipple is often called a teat when referring to non-humans. Nipple or teat can also be used to describe the flexible mouthpiece of a baby bottle. In humans, the nipples of both males and females can be stimulated as part of sexual arousal. In many cultures, human female nipples are sexualized, or "regarded as sex objects and evaluated in terms of their physical characteristics and sexiness." Anatomy In mammals, a nipple (also called mammary papilla or teat) is a small projection of skin containing the outlets for 15–20 lactiferous ducts arranged cylindrically around the tip. Ma ...

Apocrine
Apocrine () glands are a type of exocrine gland, which are themselves a type of gland, i.e. a group of cells specialized for the release of secretions. Exocrine glands secrete by one of three means: holocrine, merocrine and apocrine. In apocrine secretion, secretory cells accumulate material at their apical (anatomy), apical ends, and this material then buds off from the cells, forming extracellular vesicle (biology and chemistry), vesicles. The secretory cells therefore lose part of their cytoplasm in the process of secretion. An example of true apocrine glands is the mammary glands, responsible for secreting breast milk. Apocrine glands are also found in the anogenital region and axillae. Apocrine secretion is less damaging to the gland than holocrine secretion (which destroys a cell) but more damaging than merocrine secretion (exocytosis). Apocrine metaplasia Apocrine metaplasia is a reversible transformation of cells to an apocrine phenotype. It is common in the breast in ...

Congenital Abnormality
A birth defect, also known as a congenital disorder, is an abnormal condition that is present at birth regardless of its cause. Birth defects may result in disabilities that may be physical, intellectual, or developmental. The disabilities can range from mild to severe. Birth defects are divided into two main types: structural disorders in which problems are seen with the shape of a body part and functional disorders in which problems exist with how a body part works. Functional disorders include metabolic and degenerative disorders. Some birth defects include both structural and functional disorders. Birth defects may result from genetic or chromosomal disorders, exposure to certain medications or chemicals, or certain infections during pregnancy. Risk factors include folate deficiency, drinking alcohol or smoking during pregnancy, poorly controlled diabetes, and a mother over the age of 35 years old. Many are believed to involve multiple factors. Birth defects may be visib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breast Feeding
Breastfeeding, or nursing, is the process by which human breast milk is fed to a child. Breast milk may be from the breast, or may be expressed by hand or pumped and fed to the infant. The World Health Organization (WHO) recommends that breastfeeding begin within the first hour of a baby's life and continue as often and as much as the baby wants. Health organizations, including the WHO, recommend breastfeeding exclusively for six months. This means that no other foods or drinks, other than vitamin D, are typically given. WHO recommends exclusive breastfeeding for the first 6 months of life, followed by continued breastfeeding with appropriate complementary foods for up to 2 years and beyond. Of the 135 million babies born every year, only 42% are breastfed within the first hour of life, only 38% of mothers practice exclusive breastfeeding during the first six months, and 58% of mothers continue breastfeeding up to the age of two years and beyond. Breastfeeding has a number ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
