Intraoperative 3D Comparison of Round and Anatomical Breast Implants: Dispelling a Myth

Background: Thanks to 3D imaging, it is possible to measure the influence of different parameters on breast augmentation. In this study, we compare the effect of different shapes and sizes of breast implants on the topography of the resulting breast. Furthermore, the impact of different breast implants on inter-landmark distances and on changes of the nipple position was assessed. Methods: This interventional prospective study was carried out on 10 female patients after collecting informed consent. 3D scans of the native and augmented breasts were performed intraoperatively with small, medium, and large sizes of both anatomical and round implants, resulting in a total of n = 130 single breast scans. These scans were analyzed for topographic shift quantification, nipple migration, and inter-landmark distances of the breast. Results: Implant size, but not implant shape leads to significant topographic shifts of the breast (p < 0.001 and p = 0.900, respectively). Both round and anatomical implants lead to a significantly higher volumetric increase in the upper quadrants compared to the lower quadrants (p < 0.001). Nipple migration into the superomedial quadrant was seen in about 90% of augmentations. No evident differences in inter-landmark distances were observed when round and anatomical implants of different sizes were compared. Conclusions: Implant size rather than shape influences the postoperative aesthetic results. No significant difference in topographic shift was found comparing round and anatomical implants, suggesting that both implant shapes result in comparable aesthetic outcomes.

59 Should The ‘Normal’ And ‘Ideal’ Nipple Position in A Male Influence the Surgeon When Planning Severe Gynaecomastia Correction?

Background The ideal nipple position of the male chest following gynecomastia surgery is well documented however with increased development of the chest muscles, the NAC placement can change, leading to the medial displacement of the nipple giving a poor aesthetic outcome. Therefore, we feel these measurements need to be applied to the patients build and take into consideration the patient's future fitness goals. Method We have analysed photographs of 3 groups of men: super- athletes, athletes and severe gynaecomastia. We assessed the proportions of the chest in relation to the NAC and the degree of ptosis. Results There is wide variation in the position of the nipple to the chest wall between each group with minor variation within each group. Based on this research we believe that surgeons should be circumspect when considering breast reduction with a Wise pattern in patients with severe gynaecomastia. In patient with increased development of the pectoralis major muscles, the NAC placement can change, leading to medial displacement of the nipple and ptosis and poor aesthetic result. Conclusions We suggest a two-stage procedure, carried out on two separate occasions wound be more ideal than a single stage as this allows better long-term better positioning of the nipple.

A Three-Step Technique for Optimal Nipple Position in Transgender Chest Masculinization

Background The ideal position of the nipple-areola complex (NAC) in the transgender population can be a challenge to determine. Objectives The authors sought to determine the best location and aesthetics of the female to male NAC. Methods Patients who underwent female to male mastectomy with free nipple grafting were included. NAC position is confirmed utilizing a vertical coordinate at the level of the 4th rib near the border of the pectoralis muscle and a horizontal coordinate determined by dividing each unilateral chest into vertical thirds from midline to anterior axillary line laterally. The NAC position is confirmed at the junction of the middle and lateral third. Symmetry is ensured bilaterally by creating a triangle and transposing it side to side; the base lies from sternal notch to inframammary fold in the midline and the apex is adjusted to the NAC. A 24-question survey utilizing a 5-point Likert scale was distributed postoperatively to assess the patient’s thoughts about their chest, nipples, scar, and overall experience with the gender affirmation process. Results Thirty-one patients were included in this study. Eighteen patients responded to the postmastectomy survey, all of whom were highly satisfied with the aesthetic result postoperatively. All patients felt comfortable with their exposed chest. Nipple location was particularly highly received with 100% satisfaction rate (mean Likert score, 4.72). Nipple size and shape received a mean Likert score of 4.17 and 3.89, respectively. Conclusions The triple confirmation technique is an easy, reproducible method to guide the surgeon in relocation of the NAC. Level of Evidence: 4

Aesthetic Breast Surgery: What Do the Measurements Reveal?

Background Do plastic surgeons really know what happens to the breast after surgery? We often think that we do, but we have very few measurements to show whether we are on the right track. Objectives Only when the surgeon can predict the changes can she or he achieve consistent outcomes. Measurements lead to understanding; understanding what the measurements show allows us to refine our approach. Methods Consecutive patients in 4 categories were analyzed: breast reduction, mastopexy, augmentation, and mastopexy-augmentation. All procedures were performed by a single surgeon and all measurements were performed by the same surgeon. A standard measuring tape was utilized, and data were collected immediately preoperatively and at each follow-up visit. Only those patients with preoperative and complete 1-year postoperative measurements were included in this review. The parameters measured were clavicle to upper breast border (UBB), UBB to nipple, suprasternal notch (SSN) to nipple, SSN to inframammary fold (IMF), and chest midline to nipple. Results The changes were consistent. The borders of the breast footprint were expanded with the addition of an implant (UBB and IMF) and reduced with the removal of parenchyma (IMF). The existing SSN to nipple position was stretched when volume was added to the breast mound and it remained unchanged from the preoperatively marked position in a breast reduction. Conclusions Although measurements are not necessary to achieve good aesthetic results in breast surgery, surgeons should understand what the measurements show and what happens to the different breast parameters.
