[Understanding Plastic Surgery Procedures] What are the characteristics and precautions of natural I-line breast augmentation?
2025-04-17
Every woman desires an attractive body and appearance.
When it comes to body shape, natural bone structure and physical conditions play a major role. Those who are born with small, flat breasts often have personal insecurities.
Director Koo Hyun-guk of DA Plastic Surgery Clinic (a full member of the Korean Society of Aesthetic Plastic Surgery) explains, “Breast augmentation can help restore confidence.”
◆ Breast Augmentation
Breast augmentation provides volume for individuals with naturally small breasts due to a slim body type, or for those whose breast size has decreased after significant weight loss.
However, since breast shape and cleavage significantly affect surgical outcomes, it is important to apply a design that allows the breasts to come together naturally and move naturally.
Director Koo states, “In the past, Y-shaped cleavage designs were common. This creates a raised, artificial look because the implants appear pushed together. Nowadays, creating an I-line cleavage is important so the breasts look naturally full rather than surgically enhanced.”
◆ I-line Breast Augmentation
I-line cleavage is characterized by a natural gathering effect and smooth movement.
To achieve an I-line design, precise dissection must extend toward the inner pectoral muscle, and sufficient volume must be added to the upper breast.
Implant size should be carefully selected based on individual body type, breast pocket depth, and chest circumference.
The type of implant is also important.
There are various implants such as Motiva, Mentor, and Sebbin, and the appropriate type and volume (cc) should be chosen according to the patient’s body.
Director Koo adds, “If there is still insufficient volume after implant placement, breast sagging may be the cause. In such cases, an inframammary fold expansion volume procedure can correct sagging by positioning the implant higher above the muscle. This widens the lower breast and raises the nipple position.”
◆ Precautions for Surgery
For natural-looking results, not only the shape but also the visibility of scars must be considered.
Incisions are typically made in the armpit or under the breast. Using minimal incision techniques and triple-layer suturing, along with intensive scar care, is important to ensure scars become less visible over time.
For safe surgery, patients should confirm whether multiple specialists collaborate on-site, rather than relying on a single surgeon.
Preoperative examinations are necessary to identify any breast-related issues or conditions and to ensure the most suitable procedure is performed.
Director Koo concludes, “Achieving a natural breast design requires creating an I-line. This involves careful planning from the extent of dissection to implant selection. Since each individual differs in body type, degree of sagging, and chest size, a comprehensive approach and collaboration among specialists are essential for safe surgery.”
If you want, I can also simplify this into a short summary or explain the differences between I-line and other breast shapes more intuitively.
