Complications and Outcomes After Gynecomastia Surgery: Analysis of 204 Pediatric and 1583 Adult Cases from a National Multi-center Database

Surgical Technique Selection in the Management of Pediatric Gynecomastia

INTRODUCTION

Although the majority of pubertal onset gynecomastia is self-resolving in nature, persistent deformity may require surgical intervention. This study aims to identify patient factors associated with surgical technique selection and proposes an algorithm for the surgical management of pediatric gynecomastia.

METHODS

A retrospective analysis was performed of all surgically managed pediatric gynecomastia patients operated on at a single institution from 2012 to 2022. Charts and patient photos were analyzed for patient and operative demographics, endocrinologic comorbidities, complications, and outcomes. Data were analyzed using bivariate and logistic regression analysis.

RESULTS

Fifty-six surgically managed gynecomastia patients less than 18 years of age were included. The average age at surgery was 16.1 years old, with a mean BMI of 26.9. Most patients were overweight or obese (54.8%) and had Simon grade IIb or greater gynecomastia (55.4%) at presentation. All patients underwent 1 of 4 mastectomy techniques with or without liposuction: inferior periareolar (n=25, 44.6%), circumareolar (n=13, 23.1%), transverse with pedicled nipple (n=4, 7.1%), or free nipple graft (n=14, 25.0%). Bivariate and logistic regression analysis revealed significant differences in sternal notch-to-nipple distance, nipple-to-inframammary fold distance, breast resection weight, and gynecomastia grade between the 4 surgical techniques used in this study. An algorithm incorporating these factors was devised to guide surgical decision-making.

CONCLUSIONS

The proposed algorithm guides surgical technique selection for pediatric gynecomastia and is contingent upon the degree of ptosis and skin excess, anticipated resection weight, and skin quality.

Effects of Gynecomastia Surgery on Readiness and Return to Duty in an Active Duty Military Population

INTRODUCTION

Simple mastectomies are routinely performed in the military health care system as gynecomastia can cause significant pain and discomfort when wearing body armor. Postoperative recovery negatively impacts personnel readiness. In this study, we sought to study time to return to duty in active duty service members who undergo surgery for gynecomastia.

METHODS AND MATERIALS

We conducted a single-center retrospective review of active duty patients undergoing a surgical operation for gynecomastia from July 2020-June 2022. A total of 96 patients were included. Our primary outcome of interest was time from surgery to return to duty. A multivariate analysis was performed to assess for factors independently associated with surgical complications including patient demographics and operative techniques.

RESULTS

The median number of days to return to duty after surgery was 28 days (IQR 13-37). The median loss of duty days because of gynecomastia without surgery was 19 days (IQR 10-21), which was different on the Mann-Whitney U test. Surgical complications were observed in 19 patients (19.7%) with the most common complications being seroma (11), hematoma (4), nipple-areolar complex necrosis (2), and infection (2). Patients with a complication have significantly more time to return to duty (28 vs. 49 days, P < .001). Risk factors associated with an increased risk of complication include ranks E1-E4, behavioral health diagnosis, "open" vs. "combined" technique with liposuction, length of operation greater than 58 minutes, and excised breast mass greater than 17.9 g.

CONCLUSIONS

Gynecomastia surgery is associated with a detriment to personnel readiness. Surgery should be reserved for patients with severe symptoms that prevent the performance of daily duties. Furthermore, factors associated with an increased risk for complications include ranks E1-E5, behavioral health diagnosis, length of operation >58 minutes, and excised breast mass >17.9 g. The operating surgeon should be mindful of these factors.

Deciphering the molecular landscape: evolutionary progression from gynecomastia to aggressive male breast cancer

BACKGROUND

Gynecomastia denotes the benign proliferation of glandular breast tissue and stands as a recognized risk factor for male breast cancer. Nonetheless, the underlying carcinogenic mechanisms orchestrating the progression from gynecomastia to cancer remain poorly understood.

METHODS

This study employed single-cell RNA sequencing (scRNA-seq) to meticulously dissect the cellular landscape of gynecomastia and unravel potential associations with male breast cancer at a single-cell resolution. Pseudotime and evolutionary analyses were executed to delineate the distinct features characterizing gynecomastia and male breast cancer. The TCGA database, along with cell-cell communication analysis and immunohistochemistry staining, was harnessed to validate differential gene expression, specifically focusing on CD13.

RESULT

From the copy number variation profiles and evolutionary tree, we inferred shared mutation characteristics (18p+ and 18q+) underpinning both conditions. The developmental trajectory unveiled an intriguing overlap between gynecomastia and malignant epithelial cells. Moreover, the differential gene CD13 emerged as a common denominator in both gynecomastia and male breast cancer when compared with normal mammary tissue. Cell-cell interaction analysis and communication dynamics within the tumor microenvironment spotlighted distinctions between CD13+ and CD13- subsets, with the former exhibiting elevated expression of FGFR1-FGF7.

CONCLUSIONS

Our investigation provides novel insights into the evolutionary progression from gynecomastia to male breast cancer, shedding light on the pivotal role of CD13 in driving this transition. The identification of CD13 as a potential therapeutic target suggests the feasibility of CD13-targeted interventions, specifically tailored for male breast cancer treatment.

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.

A Retrospective Review of Arthroscopic Shaver Utilization in Adolescent Gynecomastia

Background

This study compares the arthroscopic shaver and liposuction with other established methods for treatment of adolescent gynecomastia.

Methods

Surgical management was via four operative techniques: open excision, open excision/liposuction, arthroscopic shaver/liposuction, or open excision and free nipple graft. Data were collected and compared using independent t tests, linear regression models, and one-way analysis of variance.

Results

Patients were stratified by Rohrich grades I -II (low) (N = 47) or III -IV (high) (N = 13). The groups were similar in age (P = 0.662) with lower BMI in the low-grade group (x̄ = 25.36 ± 2.1) vs. high-grade group (x̄ = 27.62 ± 4.0; P < 0.001). The low-grade group showed no significant difference in operative time across surgical techniques with decreased mean operative time in the high-grade group using the arthroscopic shaver technique (x̄ = 55.8 ± 7.56) compared with open excision (x̄ = 70.83 ± 11.02, P = 0.04), open excision plus liposuction (x̄ = 89.5 ± 24.93, P = 24.93), and open excision plus free nipple graft (x̄ = 81.67 ± 19.11, P = 0.05). There was no significant difference in complication (P = 0.84) or reoperation (P = 0.68) rates across surgical techniques regardless of grade.

Conclusions

These findings suggest that the arthroscopic shaver is safe and effective for treatment of both low- and high-grade gynecomastia in adolescents. The results yielded a similar incidence of complications and reoperation across surgical techniques, and the arthroscopic shaver approach demonstrated a shorter operative time compared with other techniques for high-grade gynecomastia.

Scar versus shape: patient-reported outcome after different surgical approaches to gynecomastia measured by modified BREAST Q®

OBJECTIVES

The challenge in the operative therapy for enlargement of the male breast is to deal with the skin excess. Shape and scars are the major parameters after which patients assess their operative result. Therefore, we assessed the satisfaction rate among patients undergoing subcutaneous mastectomy at our institution with special regard to scar tissue formation and the postoperative appearance of the chest wall in dependence of the surgical approach (periarolar versus inframammary fold).

METHODS

The study includes n = 36 male patients who underwent subcutaneous mastectomy at AGAPLESION Markus Hospital Frankfurt/Main. Patient's satisfaction dependent with the appearance of the chest wall and scar formation was evaluated by a modified BREAST Q® questionnaire plus two male-based additional questions.

RESULTS

There is no statistically significant difference in satisfaction with the operative result depending on the pattern of incision (periareolar versus submammary periareolar; 81.9% versus 75.5%) with the operative result. Evaluation of additional questions of the modified BREAST Q® questionnaire showed that 86% of the patients (n = 31) would rather have more scars and a flatter chest wall. A BMI >25 kg/m² is accompanied by a higher risk for complications (p = 0.04).

CONCLUSIONS

Periareolar incision is still the method of choice, if promising an aesthetic appealing result. When reaching its limits though, we showed that a flat and male-shaped appearance of the chest wall is priority for the patients and should therefore be for the surgeon as well.

Complications and Quality of Life following Gynecomastia Correction in Adolescents and Young Men

BACKGROUND

Persistent adolescent gynecomastia negatively affects health-related quality of life. Surgery results in psychosocial improvements, but the effects of postoperative complications on health-related quality of life are unknown. The authors examined whether complications following adolescent gynecomastia surgery impact postoperative health-related quality of life.

METHODS

Patients aged 12 to 21 years who underwent surgical correction of unilateral/bilateral gynecomastia between 2007 and 2019 were enrolled (n = 145). Relevant demographic and clinical data were obtained from medical records. Fifty-one patients completed the following surveys preoperatively, and at 6 months and 1, 3, 5, 7, 9, and 11 years postoperatively: 36-Item Short-Form Health Survey (Version 2), Rosenberg Self-Esteem Scale, and the 26-item Eating Attitudes Test.

RESULTS

Within a median period of 8.6 months, 36 percent of breasts experienced at least one complication. The most common were residual tissue (12.6 percent), contour irregularities (9.2 percent), and hematomas (7.8 percent). Patients reported significant postoperative improvements in self-esteem and in seven health-related quality-of-life domains (Physical Functioning, Role-Physical, Bodily Pain, Vitality, Social Functioning, Role-Emotional, and Mental Health) at a median of 33.3 months. Postoperative survey scores did not vary by grade or procedure, or largely by body mass index category or complication status. However, patients aged younger than 17 years at surgery scored significantly higher than older patients in the Short-Form Health Survey Vitality and Mental Health domains postoperatively.

CONCLUSIONS

Health-related quality-of-life improvements are achievable in adolescents through surgical correction of persistent gynecomastia. Postoperatively, patients largely experienced similar health-related quality-of-life gains irrespective of complication status, grade, surgical technique, or body mass index category. Minor postcorrection complications are but do not appear to limit postoperative health-related quality-of-life benefits.

Outcomes in Pediatric Thyroidectomy: Results From a Multinational, Multi-institutional Database

OBJECTIVE

Traditionally, data regarding thyroidectomy were extracted from billing databases, but information may be missed. In this study, a multi-institutional pediatric thyroidectomy database was used to evaluate recurrent laryngeal nerve (RLN) injury and hypoparathyroidism.

STUDY DESIGN

Retrospective multi-institutional cohort study.

SETTING

Tertiary care pediatric hospital systems throughout North America.

METHODS

Data were individually collected for thyroidectomies, then entered into a centralized database and analyzed using univariate and multivariable regression models.

RESULTS

In total, 1025 thyroidectomies from 10 institutions were included. Average age was 13.9 years, and 77.8% were female. Average hospital stay was 1.9 nights and 13.5% of patients spent at least 1 night in the pediatric intensive care unit. The most frequent pathology was papillary thyroid carcinoma (42%), followed by Graves' disease (20.1%) and follicular adenoma (18.2%). Overall, 1.1% of patients experienced RLN injury (0.8% permanent), and 7.2% experienced hypoparathyroidism (3.3% permanent). Lower institutional volume (odds ratio [OR], 3.57; 95% CI, 1.72-7.14) and concurrent hypoparathyroidism (OR, 3.51; 95% CI, 1.64-7.53) correlated with RLN injury on multivariable analysis. Graves' disease (OR, 2.27; 95% CI, 1.35-3.80), Hashimoto's thyroiditis (OR, 4.67; 95% CI, 2.39-9.09), central neck dissection (OR, 3.60; 95% CI, 2.36-5.49), and total vs partial thyroidectomy (OR, 7.14; 95% CI, 4.55-11.11) correlated with hypoparathyroidism.

CONCLUSION

These data present thyroidectomy information and complications pertinent to surgeons, along with preoperative risk factor assessment. Multivariable analysis showed institutional volume and hypoparathyroidism associated with RLN injury, while hypoparathyroidism associated with surgical indication, central neck dissection, and extent of surgery. Low complication rates support the safety of thyroidectomy in pediatric tertiary care centers.

Gynecomastia and Chest Masculinization: An Updated Comprehensive Reconstructive Algorithm

BACKGROUND

Gynecomastia is a common finding in males. Clinical aspect varies widely in world populations showing peculiar hallmarks according to different body shapes reflecting personal expectations; therefore, a surgical plan must be tailored on individual basis to all type of patients.

MATERIALS AND METHOD

A total of 522 patients, treated for bilateral gynecomastia from January 2007 to January 2019, were included and reviewed in this retrospective study. Considering physical status BMI, muscular trophism, hypertrophy of the mammary region, nipple-areola disorder, gland and skin cover consistency, a four-tier classification system has been used to classify the deformity and to assess a surgical plan. In all cases, a subcutaneous mastectomy was performed under direct vision.

RESULTS

No recurrence of the deformity was observed as well as major complications such as necrosis, and high level of satisfaction was observed in all groups. No breast cancer was found at the histological examinations Operative time ranged from 25 minutes up to 120 minutes and hospitalization time ranged from 1 to 3 days.

CONCLUSION

Since the physical status is strictly related to the clinical features of the disorder, a comprehensive classification system and a reconstructive algorithm are proposed.

Reoperation Because of Dissatisfaction with the Aesthetic Results of Gynecomastia Surgery: Technical Considerations

BACKGROUND

Gynecomastia is a common disease in male patients that is characterized by benign breast enlargement. Gynecomastia may involve fibroglandular tissue (FGT), supramammary fat tissue, and retromammary fat tissue (RMFT). Gynecomastia is usually treated surgically; however, some patients undergo reoperation because of dissatisfaction with the results of the first operation. This study aimed to analyze the breast conditions requiring reoperation and to identify factors requiring attention during the first gynecomastia surgery.

METHODS

We retrospectively evaluated 98 patients who underwent reoperation because of unsatisfactory esthetic outcomes from January 2014 to April 2020. According to the reasons for dissatisfaction, patients were divided into undercorrection and overcorrection groups. Patients with remnant breast tissue were assigned to the undercorrection group, while those in whom excess breast tissue was removed and was assigned to the overcorrection group.

RESULTS

The undercorrection and overcorrection groups comprised 81 and 17 patients, respectively. In the undercorrection group, 49 (60.5%) patients had residual FGT and fat tissue necessitating simultaneous FGT excision and liposuction, while 32 (39.5%) patients had no residual FGT and were treated with liposuction only. In the overcorrection group, 13 (76.5%) patients had undergone excessive removal of RMFT at the inferolateral aspect of the pectoralis major muscle margin and were treated by autologous fat grafting.

CONCLUSIONS

The most common cause of undercorrection was incomplete FGT removal, and the most common cause of overcorrection was excessive RMFT removal. Complete FGT excision and proper RMFT preservation can reduce the reoperation rate after gynecomastia surgery.

Precaution Costs: The Presumption of Breast Cancer Seeding and Its Impact on Surgical Expenditure

As healthcare costs continue to rise at unsustainable rates (at an average rate of 5.5% a year), expenses without measurable outcomes need review.¹ In reconstructive surgery, empiric change of instruments between oncologic and reconstructive segments of surgery is one such practice. Breast surgery for ductal carcinoma in situ (DCIS), prophylaxis, and partial extirpation has little possible increase in seeding or implantation risk based on the literature. With undue extrapolation from higher risk cancers (such as ovarian), preventative practices of changing out trays, re-gloving, re-gowning, re-preparing, and re-draping between phases persist in operating rooms across the country. From real case costs, the additional expense of 2 surgical setups in the United States is conservatively estimated at $1232 per case, or over $125 million per year for this theoretical risk. Using implantation risk for core breast biopsies as a denominator, this cost is $1.65–$5.8 million per potential recurrence. This is an unacceptably high cost for hypothetical recurrence risk reduction, especially one that does not impact survival outcomes.

Surgical treatment of gynaecomastia: a standard of care in plastic surgery

Background

Many techniques for the surgical treatment of gynaecomastia have been reported to be effective with reasonable limited scar formation. The aim of this study was to develop a grade adopted algorithm for effective and scar sparing techniques in reconstruction of the male breast dependent on aetiology and grading.

Methods

Operative techniques, results, rates of revisions and complications were recorded between 2006 and 2018 and results of 164 male patients were analysed, retrospectively. Skin resecting methods have been used in the earlier stage but were later replaced by minimal periareolar incisions and subcutaneous mastectomy. Resections were combined with ultrasound-assisted liposuction up to grade 2b and inferior pedicled breast reduction in 3rd degree gynaecomastias resulting in reduction of scars and effective removal of breast tissue.

Results

Retrospective analysis showed that a periareolar mastopexy was used in 24% of patients with gynaecomastia grade I, IIa and IIb to reshape the breast after subcutaneous mastectomy in the early stage of this study from 2006 to 2010. With the established standardised use of ultrasound-assisted liposuction, only 2% of patients required a mastopexy in the following years. In grade 3 gynaecomastia, the classical approach resulting in an inverted t-scar was later abandoned for an approach with a periareolar and submammary scar and inferior dermoglandular flap. The rate of secondary surgery with the used techniques did not increase.

Conclusions

When using standardised techniques in reshaping the male breast, an aesthetically pleasing and safe result can be achieved by scar sparing techniques in a safe single-stage procedure.

Mastectomy in Transgender and Cisgender Patients: A Comparative Analysis of Epidemiology and Postoperative Outcomes

Background:

Mastectomy is a commonly requested procedure in the transmasculine population and has been shown to improve quality of life, although there is limited research on safety. The aim of this study was to provide a nationwide assessment of epidemiology and postoperative outcomes following masculinizing mastectomy and compare them with outcomes following mastectomy for cancer prophylaxis and gynecomastia correction in cisgender patients.

Methods:

The American College of Surgeons National Surgical Quality Improvement Program database from 2005 to 2017 was queried using International Classification of Diseases and Current Procedural Terminology codes to create cohorts of mastectomies for 3 indications: transmasculine chest reconstruction, cancer risk-reduction (CRRM), and gynecomastia treatment (GM). Demographic characteristics, comorbidities, and postoperative complications were compared between the 3 cohorts. Multivariable regression analysis was used to control for confounders.

Results:

A total of 4,170 mastectomies were identified, of which 14.8% (n = 591) were transmasculine, 17.6% (n = 701) were CRRM, and 67.6% (n = 2,692) were GM. Plastic surgeons performed the majority of transmasculine cases (85.3%), compared with the general surgeons in the CRRM (97.9%) and GM (73.7%) cohorts. All-cause complication rates in the transmasculine, CRRM, and GM cohorts were 4.7%, 10.4%, and 3.7%, respectively. After controlling for confounding variables, transgender males were not at an increased risk for all-cause or wound complications. Multivariable regression identified BMI as a predictor of all-cause and wound complications.

Conclusion:

Mastectomy is a safe and efficacious procedure for treating gender dysphoria in the transgender male, with an acceptable and reassuring complication profile similar to that seen in cisgender patients who approximate either the natal sex characteristics or the new hormonal environment.

3D Mammometric Changes in the Treatment of Idiopathic Gynecomastia

BACKGROUND

Three-dimensional surface imaging (3DSI) has shown promise for plastic surgeons to objectively assess changes in body contour and breast volume.

OBJECTIVES

To assess the surgical outcome after bilateral subcutaneous mastectomy (BSM) and water jet-assisted liposuction (WAL) as treatment for idiopathic gynecomastia, using 3DSI to document changes regarding nipple-areolar complex (NAC) and breast volume.

METHODS

Thirty male patients (Simon II A to B) receiving BSM and WAL were enrolled. Eight subjects received additional mastopexy and NAC reduction. Use of a Vectra 3D Imaging System^® before and 6 months after surgery provided data regarding changes of NAC placement and NAC and breast dimensions. The sum volume of intraoperatively approximated lipoaspirate before and after centrifugation and mastectomy specimens quantified using water displacement were compared with 3D-assessed differences in volume.

RESULTS

When compared to the NAC dimensions defined during surgery, patients receiving NAC reductions showed nonsignificant postoperative changes in NAC dimensions. Patients without additional mastopexy showed a significant (p < 0.001) vertical (15.7 ± 14.3%) and horizontal (17.1 ± 15.0%) reduction in NAC diameter. 3D volume changes (92.8 ± 26.4 mL) showed significant differences (p < 0.001) 6 months after surgery compared to the intraoperatively measured lipoaspirate before (182 ± 54.5 mL) and after (120 ± 34.6 mL) centrifugation.

CONCLUSION

Although it is clear that patient satisfaction must remain the prime focus of surgical body contouring, 3DSI has proven valuable to objectively demonstrate both the anticipated outcome and further findings regarding treatment of idiopathic gynecomastia.

The Effect of Surgical Treatment for Gynecomastia on Quality of Life in Adolescents

PURPOSE

Despite the psychosocial deficits associated with gynecomastia, surgical treatment of adolescent gynecomastia remains controversial. This longitudinal cohort study measures changes in health-related quality of life following surgical treatment of gynecomastia in adolescents.

METHODS

The following surveys were administered to adolescents with gynecomastia and male controls, aged 12-21 years: Short-Form 36v2 (SF-36), Rosenberg Self-Esteem Scale (RSES), and Eating-Attitudes Test-26. Subjects completed surveys at baseline and postoperatively/at follow-up at 6 months, 1 year, 3 years, and 5 years.

RESULTS

From 2008 to 2017, 44 patients undergoing surgical treatment of gynecomastia and 64 unaffected male controls participated in our study. At baseline, gynecomastia patients scored significantly worse than controls on the RSES and in five SF-36 domains: general health, vitality, social functioning, role-emotional, and mental health. Scores significantly improved postoperatively on the RSES, and in four SF-36 domains: physical functioning, role-physical, bodily pain, and social functioning. Postoperatively, gynecomastia subjects scored similarly to controls in all SF-36 domains and the RSES. Young and overweight/obese patients and those with severe gynecomastia had the greatest postoperative improvement across survey measures.

CONCLUSIONS

Surgical treatment of gynecomastia significantly improves the quality of life of adolescents, with measurable improvements in physical and psychosocial functioning. Postoperatively, gynecomastia patients performed comparably to unaffected controls. Surgical treatment of gynecomastia in adolescents and young men has the potential to significantly improve quality of life, particularly in younger and overweight/obese patients and those with moderate to severe gynecomastia. Concerns regarding patient age and body mass index alone should not contraindicate surgery.

[Liposuction]

Liposuction began in the 1920s when the Parisian surgeon Charles Dujarier became interested in body shaping and fat removal. Today, it is estimated that 1,453,000 liposuctions are annually performed worldwide. In Germany, 45,000 liposuctions are performed annually. The majority of liposuctions are performed as self-pay services. The aim of this article is to outline the development of liposuction, to explain the various liposuction procedures and methods, to clarify the indications for treatment, and point out the complications and pitfalls described in the literature.
