Breast ptosis (ptosis) is a common breast morphology abnormality in clinical practice. Especially with age, pregnancy, lactation and weight changes, the supporting structure of breast tissue is damaged, resulting in a drop in breast position and changes in appearance. Scientific evaluation of breast ptosis is of great significance for formulating reasonable treatment plans and prevention strategies. This article systematically discusses the physical indicators that need to be paid attention to in the evaluation of breast ptosis, and strives to provide a reference for clinical and scientific research.
1. Definition and classification of breast ptosis
Breast ptosis refers to the decrease in the position of the breast tissue relative to the chest wall and the nipple relative to the base of the breast. Clinically, it is often classified into mild, moderate and severe ptosis based on the position of the nipple relative to the inframammary fold. Accurate classification helps to assess the severity and formulate surgical plans.
2. Physiological and pathological mechanisms of breast ptosis
The shape of the breast is mainly composed of mammary tissue, adipose tissue, connective tissue and skin. Its shape stability depends on the elastic support of connective tissue ligaments (Cooper ligaments) and skin. With age, collagen and elastin fibers decrease, and skin elasticity decreases. During pregnancy and lactation, the volume of mammary tissue changes frequently and the supporting tissue is easily damaged. Repeated fluctuations in weight also aggravate skin sagging, all of which can lead to sagging breasts.
3. Important physical indicators for breast ptosis assessment
The evaluation of breast ptosis requires comprehensive consideration of multiple body indicators to fully reflect the structure and function of the breasts. The main indicators include:
Nipple to Inframammary Fold Distance (N-IMF)
This distance reflects the vertical position of the nipple relative to the base of the breast and is a key indicator for assessing breast sagging. Under normal circumstances, the nipple should be located above the inframammary fold line. The greater the distance, the more obvious the degree of sagging.
Nipple to Sternal Notch Distance (N-SN)
It is used to evaluate the relative position of the nipple and the upper edge of the sternum, reflecting the change in the overall height of the breast drape. This indicator helps to determine the overall change in the position of the breast.
Breast volume and shape
Breast volume changes are closely related to the degree of sagging. Volume reduction is often accompanied by skin sagging, resulting in insufficient support. Volume assessment is usually performed through three-dimensional scanning or measuring the difference in breast circumference.
Skin elasticity and laxity
The elasticity of the skin directly affects the breast support capacity. The elasticity index is measured using a skin elasticity instrument, combined with the clinical finger traction method to assess skin laxity.
Weight and Body Mass Index (BMI)
Weight changes affect the amount of fat tissue and skin tension. Body mass index reflects the degree of obesity and is closely related to changes in breast morphology.
Age and physical condition
Increasing age leads to loss of collagen, pregnancy and breastfeeding cause fluctuations in breast volume, and hormonal changes during menopause also affect the elasticity of breast tissue.
Connective tissue supports structural status
The degree of damage to Cooper's ligaments and skin supporting structures affects breast stability, and imaging examinations (such as MRI) can assist in the assessment.
IV. Evaluation Methods and Techniques
Clinical measurements
Use a soft tape measure to measure N-IMF, N-SN and other indicators, and combine visual inspection and palpation to evaluate breast morphology and skin condition.
Photogrammetry
Standard body position photography was used to record breast morphology, and image analysis software was used for quantitative measurement to improve the objectivity and repeatability of the assessment.
3D Scanning
Three-dimensional volume scanning technology can accurately measure breast volume and shape, providing data support for evaluating breast ptosis and postoperative effects.
Skin elasticity test
The elastic modulus and recovery capacity of the skin were measured using an elasticity meter, and the degree of skin sagging was quantitatively analyzed.
Imaging assistance
MRI or ultrasound is used to evaluate the state of breast tissue and connective support structures and to assist in determining the pathological mechanism of prolapse.
5. Comprehensive analysis of factors related to breast ptosis
Breast sagging is the result of multiple factors. In addition to the above indicators, genetic factors, lifestyle habits (such as smoking, frequent and strenuous exercise), bra wearing habits, etc. need to be considered. Smoking accelerates collagen degradation and affects skin elasticity; non-supportive bras may increase the burden on the breasts.
6. Clinical significance of breast ptosis assessment
Accurate evaluation metrics help to:
①, determine the degree of sagging and choose the appropriate corrective surgery plan (such as lifting surgery, implantation of prosthesis, etc.);
②. Evaluate postoperative recovery and effect monitoring;
③. Prevent further sagging of breasts and formulate lifestyle and care recommendations;
④. Provide data basis for relevant scientific research and promote the development of breast beauty and reconstruction technology.
Beauty Encyclopedia Tips:
The scientific assessment of breast sagging relies on multi-dimensional physical indicators, including nipple position, breast volume, skin elasticity and overall physical condition. Combining these indicators can help to fully understand the functional status of the breast support structure and guide personalized treatment and care plans. Maintaining good living habits, reasonable weight management and scientific bra wearing are important measures to delay breast sagging. Clinicians should combine modern measurement technology to carefully evaluate the specific situation of each patient and promote the standardization and precision of breast health management.
