Liposuction Assisted Gynecomastia Surgery With Minimal Periareolar Incision: a Systematic Review

A comparative study on the short-term and long-term efficacy of endoscopic lipolysis, liposuction, and traditional open excision in gynecomastia treatment

OBJECTIVE

This study investigates the comparative short-term and long-term efficacy of endoscopic lipolysis and liposuction versus traditional open excision in the treatment of gynecomastia.

METHODS

A total of 140 male patients diagnosed with gynecomastia and admitted to our hospital from April 2021 to May 2022 were enrolled in this study. Patients were randomly assigned to two groups based on the surgical treatment method: the control group (traditional open excision, n = 70) and the observation group (liposuction under endoscope, n = 70). Comprehensive demographic and clinical data were collected for both groups. Surgical indicators, postoperative complication rates, and pain levels measured using the Visual Analog Scale (VAS) one month post-surgery were observed and compared. Additionally, recurrence rates and patient satisfaction scores were evaluated one year after the procedure.

RESULTS

There were no significant differences in demographic and clinical characteristics between the two groups (P > 0.05). The observation group exhibited shorter incision lengths, reduced operation times, and decreased hospital stays compared to the control group (P < 0.05), alongside less intraoperative bleeding (P < 0.05). The incidence of postoperative complications was significantly lower in the observation group (P < 0.05). At one and three weeks post-surgery, the observation group reported lower VAS scores for pain compared to the control group (P < 0.05). There were no significant differences in recurrence rates between the groups one year post-surgery (P > 0.05). However, the observation group achieved higher scores in terms of chest appearance, wound scarring, nipple and areola aesthetics, and overall satisfaction (P < 0.05).

CONCLUSION

Endoscopic lipolysis and liposuction not only demonstrate advantages such as lower complication rates and expedited recovery in the treatment of gynecomastia but also provide long-term efficacy comparable to traditional surgical methods. This approach significantly enhances patient satisfaction, establishing it as a preferred treatment option due to its safety profile and ability to deliver superior cosmetic outcomes.

Single Axillary Incision Versus Triple Lateral Chest Wall Incisions in Endoscopic Mastectomy for Gynecomastia: A Single-Center Retrospective Analysis with Propensity Score Matching

BACKGROUND

Endoscopic mastectomy has gradually become an important surgical modality for the treatment of breast diseases, and is the preferred procedure for gynecomastia. However, endoscopic mastectomy presents challenges such as a steep learning curve, prolonged surgical duration, increased hospitalization costs, and high technical difficulty. This study aimed to evaluate the clinical efficacy and patient satisfaction of endoscopic mastectomy using a single axillary incision versus a triple lateral chest wall incision for gynecomastia.

METHODS

Patients were stratified into a single-port group and a three-port group based on the surgical approach. Propensity score matching was used for the nearest neighbor matching, adjusting baseline data differences at a 1:1 ratio, with a caliper value set at 0.2 to ensure comparability between the two groups. Clinical efficacy and patient satisfaction were compared after propensity score matching.

RESULTS

A total of 36 pairs of patients were successfully matched after propensity score matching, with no differences in baseline characteristics (P > 0.05). Notably, the three-port group experienced longer surgical durations compared to the single-port group, alongside higher hospitalization costs (P < 0.05). There were no differences in surgical bleeding volume, postoperative drainage volume, extubation time, postoperative hospitalization time , surgical complications, visual analog scale pain scores, and recurrence rate (P > 0.05). After a 6-month follow-up, the vancouver scar scale assessment showed no differences in scar color, thickness, vascularity, softness, and total score (P > 0.05). Based on the BODY-Q questionnaire chest module scores, the single-port group showed better overall satisfaction in appearance (P = 0.038), especially in the smoothness of the chest wall, with significantly higher scores than the three-port group (P = 0.001). No differences were found in nipple symmetry, nipple sensation, and skin redundancy (P > 0.05).

CONCLUSION

The single axillary incision endoscopic mastectomy demonstrated advantages in shorter surgical duration and lower hospitalization costs, while providing a smoother chest wall appearance, thereby enhancing overall patient satisfaction. Consequently, this surgical approach may arise as one of the preferred procedures for gynecomastia.

Gynecomastia Surgery in 4996 Male Patients Over 14 Years: A Retrospective Analysis of Surgical Trends, Predictive Risk Factors, and Short-Term Outcomes

BACKGROUND

The high prevalence of benign male breast tissue enlargement (gynecomastia) has resulted in a marked increase of gynecomastia cases. While about one third of male adults experience some form of gynecomastia, gynecomastia surgery (GS) outcome research is limited to small study populations and single-center/-surgeon databases. In this study, we aimed to access the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database to identify preoperative risk factors for complications and investigate postoperative outcomes of GS.

METHODS

In this retrospective study, we queried the ACS-NSQIP database from 2008 to 2021 to identify male adult patients who underwent GS. Postoperative outcomes involved the occurrence of any, surgical and medical complications, as well as reoperation, readmission, and mortality within a 30-day postoperative time period. Univariable and multivariable assessment were performed to identify risk factors for complications while adjusting for possible confounders.

RESULTS

The study included 4,996 GS patients with a mean age of 33.7 ± 15 years and BMI of 28.2 ± 5.1 kg/m2. White patients constituted 54% (n = 2713) of the cohort, and 27% (n = 1346) were obese. Except for 2020, there was a steady increase in GS cases over the study period. Outpatient surgeries were most common at 95% (n = 4730), while general surgeons performed the majority of GS (n = 3580; 72%). Postoperatively, 91% (n = 4538) of patients were discharged home; 4.4% (n = 222) experienced any complications. Multivariable analysis identified inpatient setting (p < 0.001), BMI (p = 0.023), prior sepsis (p = 0.018), and bleeding disorders (p = 0.047) as independent risk factors for complications.

CONCLUSION

In this study, we analyzed 4996 male adult GS patients from the ACS-NSQIP database, revealing an increased caseload and significant general surgeon involvement. Risk factors like bleeding disorders, inpatient status, and prior sepsis were linked to postoperative complications, while BMI was crucial for predicting adverse events. Overall, our findings may aid in enhancing patient care through advanced preoperative screening and closer perioperative management.

Effective minimally invasive strategy for mixed-type gynecomastia using vacuum-assisted mastectomy and power-assisted liposuction

INTRODUCTION

Mixed-type gynecomastia is a benign male breast condition characterized by the proliferation of glandular and adipose tissues. Conventional open surgery has been the main approach for treating gynecomastia. However, this method has been associated with complications, including breast deformity, noticeable scar, nipple necrosis, and hypoesthesia. In contrast, vacuum-assisted biopsy systems and liposuction have demonstrated significant advantages in minimally invasive breast surgery.

AIMS

Our study aimed to investigate the effectiveness of combining vacuum-assisted mastectomy with power-assisted liposuction (VAM+PAL) for patients with mixed-type gynecomastia compared to conventional open surgery.

METHODS

Sixty patients with mixed-type gynecomastia, treated between January 2019 and June 2023, were included in this study. VAM+PAL was performed on 30 patients (59 breasts), and open excision with periareolar approach was performed on 30 patients (59 breasts). The efficacy, complications, outcomes, scar cosmesis, and patient satisfaction were assessed.

RESULTS

Compared to open excision group for gynecomastia, the VAM+PAL group demonstrated a substantial reduction in incision size (4.47 ± 1.21 cm vs. 0.97 ± 0.74 cm, p < 0.001) and lower scores of Vancouver scar scale (3.23 ± 2.27 vs. 1.10 ± 1.47, p < 0.001). No drainage tubes were required for postoperative hematoma/seroma prevention. The patients in the VAM+PAL group had significantly lower complication rates (18.64% vs. 3.39%, p = 0.008), particularly in bruise and hypoesthesia. All VAM+PAL patients reported superior satisfaction with the outcomes in breasts and nipples.

CONCLUSION

The combination of vacuum-assisted mastectomy and power-assisted liposuction can be used as an efficient minimally invasive method to treat mixed-type gynecomastia with acceptable complications, superior scar cosmesis, and satisfying outcomes.

Experience in the use of circular incision bi-pedicled vertical flap based mastectomy for grade III gynecomastia: A case series

INTRODUCTION AND IMPORTANCE

Surgical management of grade III gynecomastia with excess redundant skin is challenging. The choice of the surgical technique is mainly decided upon the size of the gynecomastia, the skin redundancy and correction of nipple position.

CASE PRESENTATION

We report our experience in the use of the circular incision bi-pedicled vertical flap based mastectomy for grade III gynecomastia according to Simon classification. This is a retrospective study conducted between January 2022 and April 2023 at two selected units in Sri Lanka.

CLINICAL DISCUSSION

A total of 7 patients with bilateral grade III gynecomastia were included in this study with a median age of 24 years (range: 18-42 years). The mean BMI was 23.2 kg/m2. All patients exhibited near symmetrical breasts and large areolar diameters. All patients complained of physical and psychological dissatisfaction with their condition and sought an aesthetic correction. Two patients were diagnosed with Klinefelter syndrome and others were apparently healthy. The main complication was seroma formation (7/7). No patients developed haematoma. Nipple hypothesia was noted in two patients which improved on follow up. The mean follow- up duration was 4-9 months. The survey of patient satisfaction showed 9 for contour, 8.6 for wound scars, 9.2 for overall satisfaction and 9.6 for improvement in self-confidence.

CONCLUSION

The above surgical technique achieved satisfactory aesthetic results while avoiding unsightly scars or serious complications and can be considered in the surgical decision making for grade III gynecomastia.

Single Axillary Incision Reverse Sequence Endoscopic Nipple-Sparing Mastectomy in the Management of Gynecomastia: Short-Term Cosmetic Outcomes, Surgical Safety, and Learning Curve of the Preliminary 156 Consecutive Procedures from a Prospective Cohort Study

BACKGROUND

Currently, a standard, optimal surgical procedure is still lacking for gynecomastia. Despite the development of a variety of surgical interventions, these techniques were often limited to patients with Simon I and II. The present study aimed to introduce a novel technique for all types and grades of gynecomastia, and reported the preliminary results.

METHODS

Patients who received single axillary incision reverse sequence endoscopic nipple-sparing mastectomy (R-E-NSM) from March 2021 to March 2023 were enrolled at a single institution. The data from 3-month follow-up cut-off were collected prospectively and analyzed to determine the short-term esthetic and safety results of this technique, as well as the learning curve.

RESULTS

A total of 159 single axillary incision reverse sequence endoscopic nipple-sparing mastectomy procedures were performed in 81 gynecomastia patients. Among these 81 patients, 7 patients (8.6%) were classified as Simon grade I, 29 patients (35.8%) as grade IIa, 24 patients (29.6%) as grade IIb, and 21 patients (25.9%) as grade III. In the patient-reported cosmetic results, the overall satisfaction score was 8.4 ± 1.4. A total of 74.1% of patients were highly satisfied, and 25.9% were satisfied. The overall complication rate was 10.1%, and only 1 patient had a major complication. According to the cumulative sum plot analysis, approximately 12 cases were needed for surgeon B and 11 cases for surgeon C to decrease their operation time significantly.

CONCLUSIONS

R-E-NSM is safe and effective for all Simon grade gynecomastia patients, with excellent cosmetic results and a short learning curve. However, a long-term follow-up assessment is still needed.

Liposuction and port site nipple sparing mastectomy: an alternative method for the operative treatment of gynecomastia at Alexandria main university hospital

BACKGROUND

Gynecomastia is characterized by unusually large masses that radiate concentrically from the base of the nipple and is caused by abnormal growth of the glandular tissue of the male breast. An alternative strategy for the surgical treatment of gynecomastia was used in this experimental study, which aims to use liposuction and port site nipple sparing mastectomy.

METHODS

The study was conducted in the surgical oncology unit at Alexandria Main University Hospital included 103 patients with a mean age of 27 and no medical history. 100 patients had bilateral gynecomastia, and three patients had unilateral gynecomastia,with two having it on the right side and one on the left.

RESULTS

Among the 103 participants, 83 had grade II gynecomastia and 20 had grade I. Only one of the three patients who participated in the study had an expanding hematoma on one side that needed to be surgically evacuated in the operating room. None of our patients experienced an infection or seroma following surgery. Furthermore, only three of our patients experienced nipple areolar complicated superficial epidermolysis, which need regular dressings until recovery. Of the 103 patients, 97 (94.17%) were pleased with the outcomes.

CONCLUSION

Liposuction and port site nipple sparing mastectomy are viable options for treating grade I to II gynecomastia, particularly if the patient prefers a more aesthetically pleasing chest contour; no scars equals better patient satisfaction.

Comparison of Soluble and Liposome Encapsulated, Sustained Release Latanoprost for Focal Adipose Reduction

Background: To address the lack of non-cytotoxic, non-surgical options to treat undesirable focal adiposity of the face, we propose use of the anti-glaucoma medication and prostaglandin F2α analogue latanoprost, which has a well-described side effect of periorbital adipose shrinkage. Objective: To evaluate the safety and efficacy of soluble and liposomal latanoprost for focal fat reduction. Approach: To compare efficacy, single administrations of either the FDA-approved cytolytic drug deoxycholic acid (DOCA), latanoprost, or liposomal latanoprost were injected into ob/ob mouse inguinal fat pads. Study outcomes included mouse weight, inguinal fat pad volume, architecture, and cytotoxicity. Results: Both DOCA and soluble latanoprost significantly reduced inguinal fat pad volume whereas liposome encapsulation reduced inguinal fat pad volume insignificantly over the 14-day study period. Hematoxylin and eosin demonstrated effective reduction in adipocyte volume without histologic evidence of cytolysis or inflammation whereas DOCA caused dermal ulcerations, adipocyte lysis, and increased tissue inflammation. Conclusion: Latanoprost reduced fat volume without inducing cell lysis or inflammation.
