Gynecomastia: A systematic review

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.

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.

Understanding the needs of women undergoing breast ultrasound: Are male radiologists still needed?

INTRODUCTION

A trend towards less male radiologists specializing in breast ultrasound was observed. A common notion in the field of breast radiology is, that female patients feel more comfortable being treated by female radiologists. The aim of the study was to understand and report the needs of women undergoing breast ultrasound with regards to the sex of the radiologist performing the investigation.

METHODS

Informed consent was obtained from all patients prior to inclusion in a prospective bi-center quality study. At center 1 (72 patients), the women were examined exclusively by female radiologists, at center 2 (100 patients) only by male radiologists. After the examination the patients were asked about their experiences and their wishes for the future.

RESULTS

Overall, women made no distinction between female and male radiologists; 25% of them wanted a female radiologist and 1.2% wanted a male radiologist. The majority (74%) stated that it made no difference whether a female or male radiologist performed the examination. The majority of women in group 2, who were investigated exclusively by male radiologists, stated that they had no preferences with regard to the sex of the radiologist (93%); 5% of the women wished to be investigated solely by a female radiologist and 2% exclusively by a male radiologist.

DISCUSSION

The majority of women undergoing breast ultrasound are unconcerned about the radiologist's sex. It would appear that women examined by male radiologists are less selective about the sex of the examining radiologist.

TRIAL REGISTRATION

Written informed consent was obtained from all patients. All patient data were anonymized. The physicians had no access to any further personal data. National regulations did not require dedicated ethics approval with anonymized lists or retrospective questionnaires.

Treatment Options for the Clinical Management of Axillary Breast Tissue

Background

Axillary breast tissue includes any combination of fat, nipple, areolae, and glandular tissue alongside breasts and affects 2%-6% of women and 1%-3% of men. Patients may experience functional and/or cosmetic concerns due to axillary breast tissue. There are nonsurgical options for its removal, such as CoolSculpting and Kybella, and surgical options such as liposuction, BodyTite liposuction, and excision. Determining which technique to use in each case is critical in achieving an excellent outcome. Currently, there are no established treatment algorithms for the removal of axillary breast tissue.

Methods

A retrospective review between January 1, 2013, and June 20, 2022, was performed. Data that were extracted included age, BMI, date of procedure, procedure, fat suctioned, tissue excised, and follow-up period. The authors analyzed outcomes and formulated a treatment algorithm based on tissue type (fat versus glandular), amount of tissue excess, skin laxity, and accessory nipple presence.

Results

A total of 43 patients (83 axillae) met our inclusion criteria and were included in our analysis. All patients were female with a mean age of 35.5 ± 10.9 years, a mean BMI of 23.0 ± 3.1, and a mean follow-up period of 8.8 ± 11.1 months. For inclusion, patients had to have undergone CoolSculpting, liposuction, BodyTite liposuction, liposuction with excision, or excision alone. All patients tolerated the procedures well and reported no serious complications.

Conclusions

Nonsurgical and surgical removal of axillary breast tissue is safe and effective. The algorithm presented can be utilized by plastic and reconstructive surgeons to ensure optimal results for axillary breast tissue removal.

Efficacy and Safety of Cold-Induced Noninvasive Targeted Fat Reduction in Pseudogynecomastia

BACKGROUND

Treatment options for pseudogynecomastia are limited, and the demand for noninvasive breast fat reduction is increasing.

OBJECTIVE

We evaluated the efficacy and safety of a cold-induced lipolysis device for treating pseudogynecomastia.

METHODS

In this 16-week prospective trial, a total of 15 male patients with pseudogynecomastia were treated twice with cryolipolysis. The primary endpoint was a change in the chest circumference from baseline at posttreatment week 8. Secondary endpoints were changes in body weight, fat thickness assessed using ultrasonography, independent evaluator- and patient-rated improvement, and Simon's gynecomastia class (SGC) grading.

RESULTS

The primary assessment, a reduction of 3.05 cm in the mean chest circumference at 8 weeks post-treatment compared to baseline, was statistically significant. The treatment effect was cumulative, with a steady decrease in chest circumference and fat thickness over the 16-week study period. The mean pain score immediately after the first session of treatment was 2.0±1.36, based on a scale of 0~10, with a score of 10 being the worst pain ever experienced. The pain decreased substantially after the end of the procedure.

CONCLUSION

Cryolipolysis was demonstrated to be an effective and safe option for reducing breast fat in pseudogynecomastia. Male with mild to moderate breast enlargement without skin excess can be ideal candidates.

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.

Incidence of Complications for Different Approaches in Gynecomastia Correction: A Systematic Review of the Literature

Background

Gynecomastia is nowadays a very common disease, affecting a large cohort of patients with different ages. The aim of this literature review is to assess the incidence of complications with all proposed techniques and for combined procedures versus single approach procedures in gynecomastia correction.

Materials and Methods

A systematic review of the literature was performed to identify all reported techniques for gynecomastia correction covering a period from January 1, 1987 to November 1, 2020. For all selected papers, demographic data, proposed technique, and complications’ incidence have been recorded.

Results

A total number of 3970 results was obtained from database analysis. A final total number of 94 articles was obtained for 7294 patients analyzed. Patients have been divided into three groups: aspiration techniques, consisting in 874 patients (11,98%), surgical excision techniques, consisting in 2764 patients (37,90%), and combined techniques, consisting in 3656 patients (50,12%). Complications have been recorded for all groups, for a total number of 1407, of which 130 among “Aspiration techniques” group (14,87%), 847 among “Surgical excision techniques” group (30,64%), and 430 in “Combined techniques” group (11,76%).

Conclusions

Several techniques have been proposed in the literature to address gynecomastia, with the potential to greatly improve self-confidence and overall appearance of affected patients. The combined use of surgical excision and aspiration techniques seems to reduce the rate of complications compared to surgical excision alone, but the lack of unique classification and the presence of several surgical techniques still represents a bias in the literature review.

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

BACKGROUND

This study aims to analyse the quality of studies and revisit the liposuction assisted gynecomastia surgery performed through minimal incision.

METHODS

A systematic review, based on the literature in the PubMed, Scopus, Science Direct, and Cochrane, to the treatment of Simon's grade I and II gynecomastia was conducted using keywords "gynecomastia" AND "liposuction." Study appraisal was performed using MINORS to assess the methodological quality of the paper.

RESULTS

There were 18 out of 415 studies eligible to review. A total of 244 out of 1628 patients with the average age of 23.13 years. Liposuction facilitated the easy handling to remove the breast tissue via small incisional design; showed consistent improved quality of life in terms of satisfaction after surgery. However, the measuring method of satisfaction rate varied, resulting in difficulties to interpret the results. Complication rates were inconsistent throughout the studies, ranging from 0.06 to 26.67%. Reoperation rate of liposuction-assisted surgery is between 0.6 and 25%. There are only two studies of a total 25 patients that are considered as good in quality. The two studies, which discuss laser-assisted liposuction technique, show minor complication of seroma in two patients. While one study shows high patient's satisfaction rate; both studies indicate high surgeon's satisfaction rate.

CONCLUSION

Small incisional design for breast parenchymal removal in gynecomastia assisted by liposuction showed a good technical approach for consistent improvement in quality of life. However, only 2 studies reported good quality methods of non-randomized case series urging for a better quality of studies in the future.

Gynecomastia: A systematic review of pharmacological treatments

BACKGROUND

Pubertal gynecomastia (PG), a benign condition with varied reported prevalence, typically appears at 13-14 years-old and is mostly idiopathic and self-limited. Psychologic impairments are common among adolescents with gynecomastia. Surgical intervention is reserved to severe cases and is offered towards the end of puberty. Pharmacological treatment is seldom given by clinicians mainly due to insufficient published data. We conducted this systematic literature review to assess the efficacy, safety, side effects, and complications of pharmacological treatments published.

METHODS

MEDLINE, Embase, and Cochrane CENTRAL were searched for the terms "gynecomastia", "pubertal", and "adolescent" in conjunction with medications from the Selective Estrogen Receptor Modulator (SERM), aromatase inhibitors (AI), and androgens groups in different combinations to optimize the search results. Exclusion criteria included: studies based on expert opinion, similar evidence-based medicine levels studies, and studies which discuss gynecomastia in adults. Selected articles were assessed by two authors. Data collected included: the level of evidence, population size, treatment regimen, follow-up, outcomes, complications, and side effects.

RESULTS

Of 1,425 published studies found and examined meticulously by the authors, only 24 publications met all the study research goals. These were divided into 16 publications of patients treated with SERM, of whom four had AI and four androgens. In general, the data regarding pharmacologic therapy for PG is partial, with insufficient evidence-based research. Tamoxifen and SERM drugs have long been used as treatments for PG. Tamoxifen was the chosen drug of treatment in most of the reviewed studies and found to be effective, safe, and with minimal side effects.

CONCLUSIONS

Pharmacological treatment as a new standard of care has an advantage in relieving behavioral and psychological distress. Although high quality publications are lacking, pharmacological intervention with tamoxifen is appropriate in select patients. Conduction large-scale high-quality studies are warranted with various drugs.

Gynecomastia Treatment through Open Resection and Pectoral High-Definition Liposculpture

BACKGROUND

Male chest definition surgery and patients complaining of breast tissue overgrowth have been increasing in recent decades. After the authors' first report of pectoral etching in 2012, patients and surgeons became more aware about gynecomastia resection when performing pectoral enhancement. The authors present their experience with pectoral high-definition liposculpture in addition to inverted-omega incision resection for gynecomastia.

METHODS

The authors reviewed their records on pectoral high-definition lipo sculpture between January of 2005 and October of 2019 in four surgical centers in Colombia. Inclusion criteria were as follows: men diagnosed with gynecomastia and body mass index less than or equal to 32 kg/m2, adequate skin elasticity, and general good health. Photographs were taken preoperatively and 1, 3, 6, and 12 months postoperatively. Follow-up ranged from 2 months to 3 years.

RESULTS

Gynecomastia resection plus high-definition liposculpture was successfully performed in 436 consecutive men (open inverted-omega incision resection, n = 132; liposuction, n = 304). Ages ranged from 18 to 66 years. Fat grafting volume ranged from 50 to 300 cc in each pectoral muscle. Minor complications (3.2 percent) included prolonged swelling, bruising, asymmetries, and residual gynecomastia. Major complications (1.6 percent) included unilateral hematoma and localized infection. No necrosis, systemic infection, or muscle paralysis was reported. A nonstandardized survey showed a very high satisfaction index.

CONCLUSION

Gynecomastia treatment combining high-definition liposculpture to male breast tissue resection through a new, almost invisible incision allowed us to achieve an athletic and natural appearance of the male pectoral area with a very low rate of complications.

Endoscopic subcutaneous mastectomy plus liposuction via a single axillary incision for gynecomastia in Asian patients: A report of 45 cases

BACKGROUND

Most techniques for surgical correction of gynecomastia are performed by anterior and/or lateral chest incisions, showing an "operated" appearance. Our initial experience was introduced in gynecomastia with a combination of endoscopic subcutaneous mastectomy and liposuction via an axillary single incision.

METHODS

Between September 2018 and July 2019, a series of 45 male patients who had Simon grade I or II gynecomastia were enrolled in this study. The demographics, operative data, and postoperative complications were recorded in detail. Four independent observers gave their ratings by assigning scores of 1 to 5 for 6 main aesthetic aspects based on pre and postoperative photographs.

RESULTS

Endoscopic subcutaneous mastectomy combined with liposuction via an axillary single incision was performed successfully in all cases. Mean operative duration was 82.6 minutes for each side (37.5-132.5 minutes). The weight of the resected glandular tissue of the 89 breasts was 26 to 130 g and the aspiration volume was 60 to 700 mL. Three unilateral subcutaneous seromas (3.3%), 5 unilateral hematomas (5.6%), and 1 bilateral minimal skin redundancy (2.2%) were encountered. Observer-reported outcomes indicated that patients with grade Ⅰ gynecomastia had significantly better aesthetic results than those with grade Ⅱb in the aspects of symmetry, shape of nipple, shape of areola, contour regularity, and overall appearance (P < .001). Patients with grade Ⅱa gynecomastia also witnessed better improvement than grade Ⅱb in shape of nipple, contour regularity, and overall appearance (P < .05).

CONCLUSION

Endoscopic subcutaneous mastectomy combined with liposuction via an axillary single incision is a feasible minimally invasive technique for the treatment of gynecomastia. The combined method is effective in achieving satisfied aesthetic results for Simon grades I and Ⅱa gynecomastia, and it can also be an alternative choice for grade Ⅱb.

The Impact and Management of Gynaecomastia in Klinefelter Syndrome

Gynecomastia is defined as a palpable enlargement of the male breast, secondary to an increase in the glandular and stromal breast tissue. Gynecomastia is encountered in up to 80% of Klinefelter syndrome cases. The pathophysiology involves testosterone/estrogen imbalance. This review article will further explore the pathophysiology of gynecomastia along with the different lines of management.

Surgical Management of Gynecomastia: A Comprehensive Review of the Literature

Gynecomastia is a graded condition characterized by enlargement of the male breast that affects a significant proportion of the male population. A plethora of varying surgical approaches currently exists in the literature; thus this comprehensive review sought to analyze surgical practice patterns and trends as they pertain to gynecomastia grade and severity. The current literature was queried utilizing the PubMed and MEDLINE databases—based on predefined parameters and individual review, 17 studies were ultimately included. Key data points included gynecomastia grade, surgical intervention, rate of complication, including hematoma, seroma, infection, and necrosis, and drain use. Two-sample t test was utilized for further analysis. A total of 1112 patients underwent surgical treatment for gynecomastia. Skin-sparing mastectomy with or without liposuction was the most frequently used procedure followed by mastectomy with skin reduction. Major complication rates ranged from 0% to 33%, with hematoma formation being most common (5.8%) followed seroma (2.4%). There was a higher rate of hematoma/seroma formation among authors who routinely utilized drain placement (9.78% versus 8.36%; P = 0.0051); however, this is likely attributable to the large discrepancy in percentage of grade III patients found in each group (50.23% versus 4.36%; P = 0.0000). As a wide variety of surgical techniques exist for the treatment of gynecomastia, an individualized approach based upon gynecomastia grade and patient preference may assist the surgeon in providing optimal outcomes. This senior author’s preferred method for treatment of gynecomastia is illustrated in the included algorithm.

The round-the-clock technique for correction of gynecomastia

Background

Gynecomastia is a common condition that can cause severe emotional and physical distress in both young and older men. Patients in whom symptomatic recalcitrant gynecomastia persists for a long time are potential candidates for surgery.

Methods

From January 2014 to January 2016, 15 patients underwent correction of gynecomastia through a single 3-mm incision at our institution. Only patients with true gynecomastia underwent surgery with this new technique. Through the small incision, sharp dissection was performed in a clockwise and counterclockwise direction describing two half-circles. Health-related quality of life and aesthetic outcomes were evaluated using a modified version of the Breast Evaluation Questionnaire (BEQ).

Results

The patients’ average age was 23.5 years (range, 18–28 years), and their average body mass index was 23.2 kg/m² (range, 19.2–25.3 kg/m²). One case was unilateral and 14 cases were bilateral. The weight of glandular tissue resected from each breast ranged from 80 to 170 g. No excess skin was excised. Bleeding was minimal. The mean operating time was 25 minutes (range, 21–40 minutes). No complications were recorded. All lesions were histologically benign. The patients’ average score was 3.5 (on a 5-point Likert scale) in all domains of the BEQ for themselves and their partners.

Conclusions

In this study, we demonstrated the safety and reliability of a new technique that allows mastectomy through an imperceptible 3-mm incision. We obtained high patient satisfaction scores using our surgical technique, and patients reported considerable improvement in their social, physical, and psychological well-being after surgery.

Treatment of gynecomastia with prednisone: case report and literature review

This study aimed to report a unique case of primary adrenal insufficiency that was accompanied by painful gynecomastia, which was resolved by treatment with prednisone. Enlargement of the left breast with continuous weakness and generalized nausea in a male was discovered 3 months before admission. Magnetic resonance imaging of the brain was normal 1 month before presentation. A physical examination revealed that the diameter of the left breast was 5 cm and the height was 3 cm. Laboratory investigations revealed hyponatremia, with a low serum cortisol level and an elevated prolactin level. Hyperprolactinemia was suspected because of adrenal deficiency that was directly or indirectly associated with increased prolactin levels. Thus, a diagnosis of hyperprolactinemia was confirmed. Ultrasonography of the left breast showed glandular tissue hyperplasia. In the present study, treating adrenal insufficiency with prednisone relieved both gynecomastia and hyponatremia. However, gynecomastia regression and hyponatremia resolution were observed when prednisone was stopped. Gynecomastia completely resolved by re-administering prednisone. Therefore, treating the underlying disease is essential so that prednisone can be given in a timely manner.

Gynecomastia - Conservative and Surgical Management

Gynecomastia is defined as a unilateral or bilateral persistent benign mammary gland enlargement in men. Prevalence of asymptomatic gynecomastia is up to 65%. True gynecomastia must be distinguished from pseudogynecomastia. Typically, in true gynecomastia, a solid tissue mass is palpable below the nipple-areolar complex. Malignant changes such as male mammary carcinoma must always be ruled out. The causes of gynecomastia are diverse. An imbalance of female to male hormones triggers the onset of the disease. This imbalance can be caused by endogenous diseases like hyperthyroidism, chronic liver disease, primary or secondary gonadal failure, androgen resistance syndromes, medication, and drug abuse. A series of heart or hypertension medications can also trigger gynecomastia. A basic requirement of proper therapy planning is knowledge of the triggers and possible drug therapy options. Inquiring about the patient's lifestyle and medication history is essential. Drug therapy with tamoxifen may be considered at an early stage. For gynecomastia persisting over 12 months, surgical excision is the treatment of choice, and there are several surgical options available depending on the grade of the gynecomastia. A thoughtful approach to managing this condition can lead to high patient satisfaction.

Danish translation and linguistic validation of the BODY-Q Chest Module

The aim of this study was to translate and linguistically validate the patient-reported outcome (PRO) instrument body-q chest module, designed to measure outcomes following chest contouring surgery. The BODY-Q Chest Module includes two scales that measure appearance of chest and nipples. The translation and validation were performed according to the guidelines from the world health organization (who) and the international society for pharmacoeconomics and outcomes research (ISPOR). This approach involved two independent forward translations, a backwards translation, an expert panel meeting and cognitive debriefing interviews with patients. Each step was undertaken with the aim of achieving a conceptual and culturally equal instrument. This process led to a linguistically validated and conceptually equivalent danish version of the body-q chest module. The forward translation resulted in several discrepant translations of items that were harmonized to form the backward translation. This translation included three items with conceptual differences that required further revision. The revised version presented at the expert panel meeting had six items that needed to be revised due to conceptual discrepancies. The cognitive debriefing interviews led to revision of one item. The practices from the who and ispor guidelines were essential to developing a translation that preserved the meaning of the content of the body-q chest module from the original development study. The translation and linguistic validation methods used in our study could be used for further translations and validation of pro instruments. These new scales have since been field-tested as part of an international psychometric study.

Management of gynecomastia-changes in psychological aspects after surgery-a systematic review

Gynecomastia affects up to two-thirds of the male population. For many patients the psychological impact of the disease is substantial. Surgical treatment is indicated when medical treatments fail. Until now, most published research on the subject has focused on how effective surgical treatment is on correcting the cosmetic appearance of the breast. Little is known about the effect of surgical treatment on the psychological aspects of the disease. The aim of this review was to identify the psychological domains affected by the disease and the effect of surgical treatment on these. A systematic search of the published literature was performed. All studies on the subject were evaluated for inclusion and six studies were included in the review. Several of the included studies reported improvement in quality of life and several psychological domains after surgical treatment for gynecomastia. Among these domains, are; vitality, emotional discomfort, limitations due to physical aspects and limitations due to pain. Impact of surgical treatment for gynecomastia seems to be beneficial for several psychological domains. The current level of evidence on this subject is very low and future studies, examining the impact of the surgical intervention for gynecomastia on psychological domains, are greatly needed. More data on this subject could improve the pre-operative evaluation of these patients and help identify the patients that will benefit from treatment.

Gynecomastia after euthyroidism restoration in a patient with type 1 diabetes and Graves' disease

In patients with autoimmune disease, gynecomastia should not be considered as 1 of the first signs of hyperthyroidism, rather it is a breast pathology that can be present even when euthyroidism restoration is achieved. It is unknown whether the autoimmune nature of thyroid disorders or simply the hyperthyroidism effects breast changes.

A review of illicit psychoactive drug use in elective surgery patients: Detection, effects, and policy

Limited information is present in literature regarding detection of illicit drug users visiting physicians when planning elective surgery; also, there is no update manuscript that is illustrating the effects of illicit drugs use that require reconstructive surgery interventions. Aims of this manuscript are: 1) to summarize existing knowledge, and give surgeons information how to detect patients who might possible use illicit drugs; 2) to review the effects of illicit drug use that specifically require reconstructive surgery interventions; 3) to assess on existing policies on asymptomatic illicit drug users when planning elective surgery. Studies were identified by searching systematically in the electronic databases PubMed, Medline, The Cochrane Library and SveMed+. Because of the nature of research questions to be investigated (drug policy and surgery), a "systematic review" was not possible. In spite of some existing policies to detect illicit drug use in specific situations such as workplaces or acute trauma patients, there is a lack of data and lack of information, and subsequently no policy has ever been made, for detection and management of illicit drug use asymptomatic patients requesting or referred for plastic surgery interventions. This manuscript poses questions for further ethical evaluations and future policy.

The Characteristics and Short-Term Surgical Outcomes of Adolescent Gynecomastia

BACKGROUND

Most adolescent gynecomastia is resolved spontaneously in 3 years. But, persistent gynecomastia could have a negative influence on psychoemotional development on adolescence. The purpose of this study is to report the characteristics of adolescent gynecomastia patients who received the surgeries, and discuss the short-term surgical outcomes.

METHODS

Of the 1454 patients who underwent gynecomastia surgery at Damsoyu hospital from January 2014 to May 2016, 71 were adolescents. Subcutaneous mastectomy with liposuction was performed for adolescent patients who had gynecomastia for more than 3 years and showed psychosocial distress. Demographic and outcome variables were retrospectively analyzed.

RESULTS

The mean age was 17.5 ± 0.77 years old. All gynecomastia cases were bilateral. Simon's grade IIa (35 patients, 49.3%) was the most common, and grade III was not observed. Fifty-one patients (71.8%) were classified as having a glandular-type breast component. Fourteen patients (19.7%) had complications, but only 3 cases (4.2%) required revision. Most of the patients (70 patients, 98.6%) were satisfied with the esthetic results, and the average 5-point Likert score was 4.85 ± 0.40. Recurrence was not observed. As the Simon's grade increased from I to IIA, a higher BMI, larger amounts of breast tissue, and longer operation times were observed.

CONCLUSIONS

Gynecomastia that did not regress spontaneously was mostly the glandular type, so not only liposuction but also surgical removal of glandular tissue is necessary. Surgical treatment, selectively performed in patients who have had gynecomastia for 3 years, and have experienced psychosocial distress, could be an acceptable treatment for adolescent gynecomastia.

Gynecomastia: histological appearance in different age groups

OBJECTIVE

Gynecomastia is a common finding in the male population which is mostly idiopathic. The aim of our study was to analyze the histological differences in young and old patient groups and its association with recurrence rates.

METHODS

Three hundred and five gynecomastia patients (555 breasts) undergoing surgical treatment from 1997 to 2015 were divided into four groups: Group 1: 13-17 years, Group 2: 18-30 years, Group 3: 31-49 years and Group 4: 50-83 years. They were evaluated concerning clinical classification, histological differences and association with antiandrogen or steroids/immunosuppressive therapy.

RESULTS

We found that the rate of florid gynecomastia was higher in older patient groups, while fibrous gynecomastia was more common in adolescents and young adults (p = .0180). Glandular gynecomastia was more frequent in younger patients, while in the older patient groups, lipomatous gynecomastia was more common (p = .0006). Patients presenting with florid gynecomastia showed a higher rate of recurrence than patients with the fibrous type of gynecomastia (12.5 and 4.7%, respectively). Of note, 18.75% of florid gynecomastia was associated with antiandrogen agents or steroid/immunosuppressive therapy, while only 4.69% of fibrous gynecomastia was associated with antiandrogenic or immunosuppressive therapy. However, there was no increase of recurrence rates in patients using antiandrogen agents or undergoing steroid/immunosuppressive therapy.

CONCLUSIONS

Fibrous gynecomastia was found to be more common in adolescents and young adults, while the florid type was more frequent in older patients. Patients presenting with florid gynecomastia showed a higher rate of recurrence than patients with the fibrous type of gynecomastia.

Closed-Suction Drains After Subcutaneous Mastectomy for Gynecomastia: Do They Reduce Complications?

BACKGROUND

In cases of refractory gynecomastia, surgical excision of excess glandular breast tissue is often warranted. Closed-suction drain placement is commonplace; however, the effect of drains on preventing complications after male breast surgery has not been fully elucidated in the literature.

OBJECTIVE

To investigate the effect of drains on reducing seroma and hematoma after subcutaneous mastectomy for gynecomastia.

METHODS

Retrospective chart review of patients undergoing subcutaneous mastectomy for gynecomastia over a 10-year period. Charts were reviewed for demographics, BMI, comorbidities, type of local anesthesia, specimen weight, use of liposuction, and placement of drains. Outcomes were determined by seroma or hematoma in the 30-day postoperative period.

RESULTS

A total of 163 breasts were studied (group I = no-drain, n = 46; group II = drain, n = 117). Group I had a higher rate of clinically significant seromas requiring needle aspiration than group II (6.5 vs 0%, p = 0.0214). There was no difference in rates of hematoma (group I vs II, 2.2 vs 6.0%, p = 0.443) and total fluid collections (group I vs II, 19.6 vs 16.2%, p = 0.647). BMI, use of local anesthesia, specimen weight, and use of liposuction were not significantly associated with postoperative complications.

CONCLUSIONS

Closed-suction drains may reduce rates of clinically significant seromas requiring needle aspiration. Though drains carry their own pertinent adverse effects (e.g., patient discomfort and anxiety, cost, and additional clinic visits), there remains no universal standard of care and surgeon practices vary widely. Given the potential to reduce seroma rates, we recommend that surgeons consider placing drains and discuss with patients the benefits and risks of drains after surgical treatment of gynecomastia.

Gynecomastia Classification for Surgical Management: A Systematic Review and Novel Classification System

BACKGROUND

Gynecomastia is a common deformity of the male breast, where certain cases warrant surgical management. There are several surgical options, which vary depending on the breast characteristics. To guide surgical management, several classification systems for gynecomastia have been proposed.

METHODS

A systematic review was performed to (1) identify all classification systems for the surgical management of gynecomastia, and (2) determine the adequacy of these classification systems to appropriately categorize the condition for surgical decision-making.

RESULTS

The search yielded 1012 articles, and 11 articles were included in the review. Eleven classification systems in total were ascertained, and a total of 10 unique features were identified: (1) breast size, (2) skin redundancy, (3) breast ptosis, (4) tissue predominance, (5) upper abdominal laxity, (6) breast tuberosity, (7) nipple malposition, (8) chest shape, (9) absence of sternal notch, and (10) breast skin elasticity. On average, classification systems included two or three of these features. Breast size and ptosis were the most commonly included features.

CONCLUSIONS

Based on their review of the current classification systems, the authors believe the ideal classification system should be universal and cater to all causes of gynecomastia; be surgically useful and easy to use; and should include a comprehensive set of clinically appropriate patient-related features, such as breast size, breast ptosis, tissue predominance, and skin redundancy. None of the current classification systems appears to fulfill these criteria.

Is the transposition of the nipple-areolar complex necessary in Simon grade 2b gynecomastia operations using suction-assisted liposuction?

OBJECTIVE

The aim of this study was to assess the efficacy of suction-assisted liposuction (SAL) in Simon grade 2b gynecomastia and its effect on sternal notch to nipple areola (SNN) distance.

METHODS

A retrospective analysis was performed on 21 patients with grade 2b gynecomastia who underwent SAL. Preoperative and postoperative SNN distances of the patients were measured, the results were analysed using a Mann-Whitney U test and a p-value <.05 was accepted as statistically significant. Aesthetic results were evaluated by the surgical team considering five criteria: breast size, breast shape, nipple-areolar complex positioning, scarring, and skin tightness of the breast envelope. A 10-point Likert scale was used to assess patient satisfaction with SAL surgery.

RESULTS

All of the patients were followed up for an average period of 17.8 months (range = 12-28 months). The mean amount of lipoaspirate was 232 mL per breast (range = 190-310 mL). The mean preoperative SNN distance was 22.3 cm (range = 20-23.5 cm), whereas postoperative was 21.3 cm (range = 19.2-22.8 cm); the difference was statistically significant (p < .05). There was one case of nipple areola necrosis, three hypoesthesia, five persistent pains, and four slight buttonhole deformities. The aesthetic result was evaluated as very good by the surgical team, and the overall patient satisfaction rate in terms of breast shape and volume was 92%.

CONCLUSIONS

It was concluded that SAL provides a good aesthetic outcome in patients with Simon grade 2b gynecomastia and shortens the SNN distance by 1 cm, but further clinical studies are required to support this conclusion.

Unilateral gynaecomastia in a 16-month-old boy with neurofibromatosis type 1 - case report and brief review of the literature

Neurofibromatosis type 1 (NF1) is an autosomal dominant disease that shows high penetrance with a wide variability in the phenotype. Prepubertal enlargement of the breast in male subjects affected by this condition is well known, but rarely reported. The present case report describes diagnosis and therapy of unilateral gynaecomastia in a toddler showing integumental stigmata of NF1. Furthermore, the report provides a brief review of the literature concerning this finding in NF1. According to this review, the present case appears to be one of the youngest NF1-affected males affected by gynaecomastia that has been reported.
