Septum-Based Mammaplasties: Surgical Techniques and Evaluation of Nipple-Areola Sensibility

Long-term breast sensation following breast augmentation: A retrospective analysis of influencing factors

BACKGROUND

Breast augmentation is associated with high patient satisfaction; however, preserving breast sensation remains challenging. This study aimed to evaluate long-term breast sensation and identify factors affecting sensation following breast augmentation.

METHODS

This retrospective study included breast augmentation patients (experimental group) and an unoperated control group to evaluate the sensory changes following surgery. Sensory assessments were conducted using the Semmes-Weinstein monofilament test at 9 specific points on each breast, measuring central, peripheral and total sensory values. Comparisons of the sensory outcomes were made between the experimental and control groups, as well as within the experimental group. Factors such as smoking, systemic diseases, pregnancy, breastfeeding, implant plane, implant size and type and complications were analysed for their impact on sensation.

RESULTS

The study included 55 breast augmentation patients (110 breasts) and 20 controls (40 breasts). Sensory outcomes were significantly better in controls than in the operated group. Smoking, systemic diseases, implant size and type showed no significant impact on sensation. Pregnancy and breastfeeding were associated with better central sensation, whereas peripheral sensation was unaffected. Subglandular placement preserved central sensation better than dual-plane 2 and 3 placements but significantly reduced peripheral sensation. Post-operative complications were linked to decreased central sensation.

CONCLUSIONS

Breast augmentation is associated with decreased sensation compared to controls. Subglandular placement preserves central sensation better than dual-plane placement. Smoking, systemic diseases and implant size and type were not significantly related to sensory outcomes, while post-operative surgical complications were associated with diminished central sensation.

The Lipo-DIEP Flap Breast Reconstruction: A Valuable Innovation for Maximizing Abdominal Tissue Volume

Background

The deep inferior epigastric perforator (DIEP) flap is universally considered the gold standard technique for breast reconstruction (BR), though it cannot always be proposed to patients with insufficient donor-site volume. We explore the efficacy of autologous fat transfer (AFT) of the Holm abdomen zone IV in the retropectoral plane during DIEP flap reconstruction (lipo-DIEP flap), to enhance the volume provided by the abdominal donor site in patients with low body mass index (BMI).

Methods

We prospectively enrolled patients with BMI less than 25 kg/m2 and candidates for lipo-DIEP flap BR (group A) comparing them with a control group (group B) undergoing traditional DIEP flap BR with the same characteristics of the first group (BMI < 25 kg/m2). Patients belonging to group A underwent magnetic resonance imaging preoperatively and 6 months after the BR, evaluating the adipose tissue volume retained in the retropectoral space.

Results

A total of 40 breasts were included in the study. The 2 groups were homogeneous regarding the collected variables, except for mean delayed AFT sessions (0.25 versus 0.95; P= 0.00094). The average volume of retropectoral AFT was 116.25 mL (SD 31.36). Six months after the procedure, the mean retropectoral fat volume calculated through magnetic resonance imaging was 48.64 mL (SD 14.15), whereas the mean graft integration rate was 45.98% (range, 30.7%-64.2%).

Conclusions

The lipo-DIEP flap is a valuable technique for patients with insufficient donor-site volume. Immediate retropectoral fat grafting from the Holm zone IV has proven to be safe in terms of complications, reducing the need for further AFT sessions.

Radial and Ulnar Forearm Free Flaps: A Critical Comparison of Donor-Site Morbidity and Its Impact on Quality of Life

BACKGROUND

A poor evidence basis exists regarding directly comparing objective and subjective donor-site morbidity associated with the forearm flap. The authors evaluated the postoperative donor-site complications and quality-of-life outcomes between the radial forearm free flap (RFFF) and the ulnar forearm free flap (UFFF).

METHODS

All patients undergoing RFFF or UFFF harvest were included. Grip strength, pinch strength, wrist range of movement, and testing of skin sensitivity were assessed with the appropriate scales at different time intervals. In addition, appearance and quality of life were assessed using the Patient and Observer Scar Assessment Scale and the Disabilities of Arm, Shoulder, and Hand instruments.

RESULTS

Eighty patients were enrolled (RFFF, n = 40; and UFFF, n = 40). A short-term reduction in grip strength, fine motor skills (tip pinch, key pinch, palmar pinch), and range of motion was observed for the RFFF group and improved over time. None of the patients in either group experienced functional disturbance in grip strength, wrist motion, fine motor skills, or sensation to light touch at 1 year. Nine patients experienced partial skin graft loss (RFFF, n = 6; UFFF, n = 3). There was a significantly higher incidence of temporary numbness in the RFFF group ( P = 0.040). Persistent numbness occurred in 3 cases in the RFFF group. Cold intolerance was significantly lower in the UFFF group (2.5%) than in RFFF group (22.5%). Moreover, the mean Patient and Observer Scar Assessment Scale and Disabilities of Arm, Shoulder, and Hand scores were reduced at 12 months compared with 6 months, significantly superior for UFFF.

CONCLUSIONS

Objective function limitations are reversible short-term effects after forearm flap and do not affect daily routines in the long term. In addition, UFFF appears to be preferred over RFFF for subjective outcomes, which emphasizes that UFFF should be considered as an alternative to RFFF for reconstructing soft-tissue defects.

The FALD-V: A predictive formula for preoperative volume assessment of adipose tissue transplantation in FALD flap

BACKGROUND

The fat-augmented latissimus dorsi (FALD) flap is an evolution of the traditional latissimus dorsi (LD) flap, which allows to obtain a total autologous breast reconstruction (BR) avoiding the use of breast implants. The aim of this study was to develop a predictive preoperative formula in order to estimate and optimize the amount of fat to be transferred during FALD flap BR, using only anthropometric measurements.

METHODS

We conducted a prospective clinical study between September 2020 and April 2023. All patients underwent back pre-operative ultrasound scan to assess the subcutaneous skin paddle thickness (SPT) and a regression analysis was performed to evaluate which anthropometric variable had a better correlation with this thickness.

RESULTS

Data from 66 FALD flaps were collected. The mean SPT was 11.95 mm (SD 4.56). A significant correlation between SPT and body mass index (BMI) was found (r = 0.640, p < 0.0001). Using the fat-to-capacity ratio (113%), the following formula (the FALD-V) was developed to predict the needed fat transfer into FALD flap: [-509 + 12.32 × BMI + 11.71 × skin paddle width + 17.43 × skin paddle height] × 1.13. The considered variables (BMI, skin paddle width and skin paddle height) were statistically significant (p < 0.001, p = 0.0483, p = 0.0154, respectively). The cross-validation confirmed the accuracy of the formula (r = 0.810).

CONCLUSION

The FALD-V can be used as an innovative complimentary device in the planning of FALD flap one-stage total autologous BR. To enhance its application, a 3.0 WebApp at www.braflap.com (and www.breast-v.com) is available free of charge for both iOS and Android devices.

Flap neurotisation improves sensation outcomes in abdominally based autologous breast reconstruction: A systematic review and meta-analysis

BACKGROUND

Flap neurotisation is a promising solution to restore the diminished or complete loss of sensation following mastectomy. This systematic review compared sensory outcomes in neurotised versus non-neurotised abdominal-based autologous breast reconstructions to establish its benefit in routine clinical practice.

METHODS

A literature search was performed according to the PRISMA guidelines. Medline, PubMed, EMBASE, and Cochrane databases were queried for relevant studies. Pressure sensitivity, measured using Semmes-Weinstein monofilaments (SWM) or the pressure-specified sensory device (PSSD), was the primary outcome measure.

RESULTS

A total of 12 studies comprising 367 neurotised and 295 non-neurotised flap reconstructions were included, with 8 studies included in the meta-analysis. Neurotised flaps demonstrated superior sensory outcomes over non-neurotised flaps, with significant differences in SWM scores (mean difference [MD], -1.552 95% CI, -2.351 to -0.7535; p = 0.0001) and PSSD (MD -13.36; 95% CI, -26.41 to -0.3117; p = 0.0448) at follow-up (range 8 to 77 months). The differences in total skin sensation (native and flap skin combined) were statistically significant in the SWM group (p = 0.0010) but not in the PSSD group (p = 0.0649). Investigation on the factors impacting sensation recovery in neurotised flaps yielded inconclusive outcomes.

CONCLUSIONS

Neurotised flaps consistently demonstrated superior sensation outcomes compared with non-neurotised flaps, irrespective of flap type or neurotisation technique. However, further research is essential to elucidate the factors that impact sensory recovery and standardise neurotisation practices for more optimal post-mastectomy reconstruction outcomes.

Extremely rare case of unilateral gigantomastia after hormonal stimulation treated with a modified wise pattern technique: A case report

INTRODUCTION

Gigantomastia, characterized by excessive breast size (usually heavier than 2.5 kg), can result from various causes and significantly affect patients' lives. Surgical intervention is often required, and over time, several techniques have been developed for its treatment. These techniques aim to address the functional and aesthetic concerns associated with gigantomastia, providing relief to patients and improving their quality of life.

PRESENTATION OF THE CASE

A 40-year-old primiparous housewife developed unilateral gigantomastia as a consequence of hormone therapy. To address this, a modified reduction mammoplasty procedure was undertaken, incorporating NAC (Nipple-Areola Complex) grafting. The reduction involved removing 3450 g of tissue, resulting in restored breast symmetry and enabling the patient to reintegrate into normal daily life.

DISCUSSION

Compared to the traditional technique, the introduction of some modifications in the design allowed for the absence of complications such as dehiscence of the scar at the intersection of the T, the failure of the nipple graft attachment, and the maintenance of a conical shape over time, enabling complete symmetrization of the two breasts.

CONCLUSION

The use of a modified version of the Thorek technique allowed for optimal functional and aesthetic restoration even in the case of a significantly disproportionate breast compared to the contralateral one, with no complications.

Fat-Augmented Latissimus Dorsi Flap for Secondary Breast Reconstruction in Small to Medium-Sized Irradiated Breasts

BACKGROUND

Secondary breast reconstruction (BR) is recognized as a challenging procedure, particularly when radiotherapy (RT) has previously been performed. The aim of this study was to compare operative data and aesthetic outcomes between secondary irradiated and immediate BR using the fat-augmented latissimus dorsi (FALD) flap.

METHODS

The authors conducted a prospective clinical study between September of 2020 and September of 2021. Patients were divided into two groups: group A included secondary BR using the FALD flap in previously irradiated breasts, and group B included immediate BR with the FALD flap. Demographics and surgical data were compared, and an aesthetic analysis was performed. Chi-square and t tests were performed for categorical and continuous variables, respectively.

RESULTS

Twenty cases of FALD flap-based BR for each group were included. The two groups were found to be homogeneous for the demographic variables. The difference in mean operative time (263.1 minutes versus 265.1 minutes; P = 0.467) and complications ( P = 0.633) between the two groups were not significant. There was statistically significant difference in term of immediate fat grafting volume in favor of group A (218.2 cc versus 133.0 cc; P < 0.0001). Regarding aesthetic outcomes, the mean global score evaluation showed no statistically significant differences between groups (17.86 versus 18.21; P = 0.209).

CONCLUSIONS

The authors' study states that the FALD flap can be considered a reliable procedure for secondary reconstruction in previously irradiated breasts, although it is not indicated for patients with larger breasts. This surgical technique allowed us to achieve a totally autologous BR with good aesthetic results and low complication rates, even in secondary irradiated cases.

Horizontal pillar technique: A single pedicle septum-based approach in reduction mammaplasty with a twist

Breast reduction surgery has proven to be a successful treatment for various conditions such as postural disorders, anxiety, dermatological problems, and body image disorders, and is tailored to accommodate each patient's needs and anatomical variations. The author presents a modified approach for reduction mammaplasty using a septum-based superomedial pedicled nipple-areola complex (NAC) flap combined with horizontal dermoglandular pillars. This adjustment enhances desired breast projection, potentially eliminating the need for alternative pedicles in most cases. The limitations and disadvantages of this new technique are discussed. Between July 2015 and July 2021, 85 patients underwent surgery using the horizontal pillar reduction mammaplasty. Clinical data obtained during follow-up visits were recorded. Patients were asked to answer the local version of the Breast-Q, version 2.0, reduction module postoperative scale questionnaire to evaluate breast shape contentment and patient satisfaction at the 1-year follow-up. Necrosis of the NAC was not observed in any patient. The most common complaints in the early postoperative period were pain along the inframammary fold and swelling that extended into the axillary region. The mean values and standard deviations of the postoperative Breast-Q scores were calculated. The postoperative satisfaction with breasts scale mean value was 84.11 ± 12.86, and the postoperative satisfaction with outcomes scale mean value was 81.08 ± 9.97. The horizontal pillar reduction mammaplasty technique is safe, reliable, and easy to perform in breast reduction. Although the initial findings are encouraging, future anatomical and clinical studies are necessary to fully explore this modified technique's functional limitations and long-term outcomes.

Mitigating nipple areolar complex (NAC) ischemia following mastopexy augmentation using nitroglycerin application and methylprednisolone: a case report

A patient who underwent bilateral wise-pattern mastopexy augmentation with threatened nipple-areolar complex necrosis was successfully managed medically with IV methylprednisolone and topical nitroglycerin ointment as immediate consultation with the operating surgeon was not possible.

The Impact of Reduction Mammaplasty on Breast Sensation: A Systematic Review

Loss of sensation is one of the most feared complications of breast reduction surgery. Although several techniques have been proposed to maximize sensitivity preservation, the scientific literature still reports contradictory findings. This systematic review aimed to assess whether breast reduction mammaplasty is associated with measurable changes in breast sensation. This review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed (National Institutes of Health, Bethesda, MD), Scopus (Elsevier, Amsterdam, the Netherlands), and Web of Science (Clarivate, Philadelphia, PA) databases were searched for clinical studies investigating breast sensation after breast reduction mammaplasty. The initial search identified 1523 studies of which 22 articles met our specific inclusion criteria. Most of the included studies are consistent in describing only transient sensation decrease or even sensation improvement after surgery compared to the presurgery condition with any approach, except those investigating outcomes after superior or superolateral pedicle reduction mammaplasty. Nevertheless, the overall quality of evidence is low or very low due to the limited availability of randomized controlled trials or controlled studies and the high risk of bias.

Narrow inferior-central septum-based pedicle: A safe technique to improve aesthetic outcomes in breast reduction

BACKGROUND

Inferior-central pedicle has some aesthetic drawbacks, including hypertrophic scar along the inframammary fold (IMF), squaring of the breast contours, and propensity to develop long-term 'bottoming-out.' This study aimed to verify if the narrow inferior-central (NIC) septum-based pedicle can allow the surgeon to improve aesthetic outcomes compared with the traditional inferior-central pedicle approach.

METHODS

Forty breasts underwent NIC-based breast reduction (group A), and 37 underwent traditional inferior-central pedicles (group B). The NIC pedicle was drawn with a width of 3.5-4.5 cm. The recorded measurements were sternal notch to nipple distance (S-N) and nipple to IMF distance (N-IMF) at the time of preoperative markings and follow-up 1, 6, and 18 months after the procedure.

RESULTS

The two groups were homogeneous regarding demographics, operative data, and preoperative S-N and N-IMF distances. Both groups showed no total or partial nipple-areola necrosis. At the 18-month follow-up, S-N (p < 0.00001) and N-IMF (p = 0.00039) distances were statistically different between the two groups, in favour of NIC group A. Changes in N-IMF distances between the 1- and 18-month visits were statistically different among groups (p < 0.0001), with a length variation of + 17.51% and + 28.46%, respectively. Patient satisfaction rate regarding "breast shape" (p = 0.021), "lower pole appearance" (p = 0.00017), and "scar" (p = 0.047) were higher in group A.

CONCLUSION

NIC-based pedicle proved to be a safe procedure and allowed us to overcome limitations that typically characterise the inferior pedicle, i.e., 'bottoming-out' deformity, hypertrophic scar of the lower pole, and squaring of the breast contours.

The Ergonomic FALD Flap for One-stage Total Breast Reconstruction

Background

The fat-augmented latissimus dorsi (FALD) flap combines this pedicled flap with immediate intraoperative fat transfer. Very little is described concerning its inset at the mammary site. Our efforts have concentrated on seeking the best flap orientation and skin-adipose paddle shaping, to improve the aesthetic outcome and to obtain a complete breast reconstruction (BR) in one stage.

Methods

A prospective clinical study was performed in patients who underwent BR with FALD flaps, between December 2020 and March 2022. Patients were randomly enrolled into two groups: ergonomic inset of the FALD flap with vertical orientation of the skin-adipose paddle (group A) and FALD flap with traditional horizontal paddle orientation (group B). The study's endpoints were the evaluation of the aesthetic outcomes (from patients' and surgeon's perspectives) and complications.

Results

Thirty-two FALD flaps (23 patients) were performed for group A, and 31 FALD flaps (25 patients) for group B. The two groups were homogeneous in terms of demographic and surgical data (P > 0.05). The overall complication rate was homogeneous among the groups, without statistically significant differences (P = 1.00). The surgeon's assessments showed a statistically significant superior aesthetic outcome in group A regarding volume, symmetry, and shape (P < 0.05). Higher satisfaction was observed in group A patients, in terms of breast size (P < 0.00001), shape (P = 0.0049), and overall satisfaction (P = 0.00061).

Conclusions

The ergonomic vertical FALD flap technique enables surgeons to perform one-stage total BR, with excellent breast projection and upper pole fullness. These refinements in flap shaping and molding reduced the need for further autologous fat transfer, obtaining a brilliant totally autologous BR without the need for microsurgical experience.

Is Preoperative Asymmetry a Predictor of Postoperative Asymmetry in Patients Undergoing Breast Reduction?

Plastic surgeons aim to achieve symmetry in breast surgeries, which is the main determinant of chest aesthetics. The aim of this study was to verify if preoperative breast asymmetry is a predictor of postoperative asymmetry in women undergoing breast reduction. In this prospective study, we enrolled 71 women (the mean age 37 years, SD 10 years) with breast hypertrophy who underwent reduction mammaplasty. We collected clinical data including age, height, weight, weight of the resected tissues, and performed pre and postoperative photographic documentation. The following measurements of both breasts were analyzed: volumes (vol), nipple-sternal notch distance (A-sn), difference between nipples' levels (A-A'), nipple-midline distance (A-ml), difference between inframammary folds levels (IF-IF'), distance between inframammary fold and nipple (IF-A), distance between inframammary fold apex and midline (IF-ml). All measurements were performed preoperatively and 6 months after the surgery and asymmetries of all variables were calculated (asy-vol, A-A', asyA-sn, asyA-ml, IF-IF', asyIF-A, asyIF-ml). Postoperative asymmetry of breast volumes and nipples position was not associated with any of the analyzed clinical variables. Postoperative asymmetry of nipples' level was associated with preoperative asymmetry of IF-ml; however, logistic regression did not detect any preoperative measurement influencing postoperative volume and nipples' level asymmetry. Moreover, we found that preoperative asyIF-ml increased the risk of postoperative volume asymmetry, which is above the average (52 cc) (OR = 2.04). Postoperative breast asymmetry after breast reduction is not related neither to preoperative asymmetries nor clinical variables; however, asymmetry of inframammary fold apex to the midline may be the factor affecting postoperative volumetric asymmetry.

The Assessment of Nipple Areola Complex Sensation with Semmes-Weinstein Monofilaments-Normative Values and Its Covariates

Objective: To establish normative data for nipple-areola complex (NAC) sensibility examined with Semmes-Weinstein monofilament test (SWMT) and two-point discrimination (TPD) in women with varying breast sizes, including women with gigantomastia. We also aimed to identify clinical variables influencing NAC sensation. Methods: A total of 320 breasts in 160 Caucasian women (mean age 33.6 years, SD 11 years) were examined (including 50 hypertrophic breasts). NACs sensation was examined using Semmes-Weinstein monofilaments (SWM) and the Weber Two-Point Discrimination Test. Results: The nipple appeared to be the most sensitive part of NAC. In normal-sized breasts, sensation thresholds (SWM) correlated with: age, BMI, history of births, breast size and ptosis (for all locations), breastfeeding history (for nipple and upper areola) and areola diameter (for all locations apart from the nipple). Regression analysis showed that age, cup size and suprasternal notch-to-nipple distance are risk factors for diminished NAC sensation. Sensation thresholds in all NAC locations of hypertrophic breasts were significantly higher compared to normal-sized breasts, while TPD tests did not differ between the groups. Conclusions: We provided normative values of NAC sensation (tactile threshold and TPD) for different NAC areas. Our investigation indicated that SWM are useful diagnostic tools when the following factors are considered while examining NAC sensation: location (nipple vs. areola), age, breast size, suprasternal notch-to-nipple distance, history of births and breastfeeding. Hypertrophic breasts presented significantly higher sensation thresholds for all NAC locations. The report may serve as a reference data for further investigations regarding NAC sensation after different breast surgeries.
