Application of "CD-4" theory for determining the width of implant in breast augmentation.

Cai J, Zhou Y - Chin. Med. J. (2015)

Bottom Line: From January 2006 to June 2014, the authors have found and applied "CD -4" theory to determine the width of breast implant (W) in dual plane I or II breast augmentation cases through transaxillary or periareolar incision for 560 patients. "CD" is defined as the curved distance on skin from the midline of the sternal bone to the anterior axillary line (AAL) on the lateral chest wall through the horizontal level on inferior mammary fold.Their new intermammary cleavages without bras are between 1 cm and 2.5 cm, and lateral borders of the breast are on the area of the AAL.For the very thin patient, 4 should be 3.5.

ABSTRACT

Background: The determination of the width of the implant is the first key step to select shape and volume of the implant in breast augmentation. The aim of this study was to introduce a new method to determine the width of the implant (W) and explain the reasons to do so in details.

Methods: From January 2006 to June 2014, the authors have found and applied "CD -4" theory to determine the width of breast implant (W) in dual plane I or II breast augmentation cases through transaxillary or periareolar incision for 560 patients. "CD" is defined as the curved distance on skin from the midline of the sternal bone to the anterior axillary line (AAL) on the lateral chest wall through the horizontal level on inferior mammary fold. W = CD - 4 (or 3.5) cm.

Results: The 560 patients used both round and anatomic implants with W from 10.5 cm to 12.5 cm. Their CDs are from 14.5 cm to 17 cm. About 78% of the patients have got followed up from 1 month to 5 years postoperatively. Except for four patients who got unilateral capsular contractions, all the other patients are satisfied with their nature new breast shapes and volumes. Their new intermammary cleavages without bras are between 1 cm and 2.5 cm, and lateral borders of the breast are on the area of the AAL.

Conclusions: W (width of the implant) = CD - 4 (cm) when doing dual plan I or II breast augmentation. For the very thin patient, 4 should be 3.5.

Figure 3: (a) Typical case 3a: Frontal view preoperatively W = CD (16 left/15.5 right) – 4 = 12 (cm). Allergan 410 MM280. We add 0.5 cm to the right W; (b) Lateral view 1 week follow-up postoperatively, the black arrow indicating the anterior axillary line moving forward about 1 cm; (c) Frontal view 6 months follow-up postoperatively; (d) Lateral view 6 months follow-up postoperatively, the most lateral margin of the breast is on the postoperative anterior axillary line.

Mentions: Among 560 patients, 62 patients chose round implant from 175 ml to 300 ml with W from 10.5 cm to 12 cm. Their CDs are from 14.5 cm to 16 cm. The other 498 patients chose anatomic implants from 220 g to 320 g with W from 10.5 cm to 12.5 cm. Their CDs are from 14.5 cm to 17 cm. 78% of the patients have got followed up from 1 month to 5 years postoperatively. Their intermammary cleavages are between 1 cm and 2.5 cm without wearing bras. If wearing tight bras, 90% of the patients got their two breasts connecting with each other, which was the most satisfied part of their new breasts. All patients’ lateral margins of the breast are not exceeding the AAL laterally. Figure 3a–3d shows a typical case. All patients are satisfied with their new nature breast shape and volume except for four patients who got unilateral capsular contractions.
