"Identifying complication risk factors in reduction mammaplasty: a single-center analysis of 1021 patients applying machine learning methods".

Various surgical approaches and pedicles have been described to ensure safe and satisfactory results in reduction mammaplasty. Although different breasts require different techniques, complications are common. This study aims to assess the incidence of complications following primary bilateral reduction mammaplasties across a diverse range of pedicle methods within one of the largest single-center cohorts to date, utilizing machine learning methodologies. A retrospective review of primary bilateral reduction mammaplasties at a single surgical center between January 2016 and March 2020 was performed. Patient medical records and surgical details were reviewed. Complications were compared among three different pedicles. Binary recursive partitioning (CART) machine learning was employed to identify risk factors. In total, 1021 patients (2142 breasts) met the inclusion criteria. The superomedial pedicle was the most frequently utilized (48.0%), with an overall complication rate of 21%. While pedicle-based subgroups demonstrated significant demographic variance, overall complication rates differed most between the inferior (24.9%) and the superomedial pedicle (17.7%). Statistical analysis identified resection weight as the sole significant independent risk factor (OR 1.001, p = 0.007). The machine learning model revealed that total resection weights exceeding 1700 g significantly increased the risk of overall complications, while a sternal notch to nipple (SNN)-distance > 36.5 cm correlated with complications involving the nipple-areola complex (NAC). Higher resection weights are associated with elevated complication rates. Preoperative assessment utilizing SNN-distance can aid in predicting NAC complications.

Variability in Postoperative Nipple Sensation by Dermoglandular Pedicle in Bilateral Breast Reduction.

BACKGROUND: Decreased nipple sensation following reduction mammoplasty can negatively affect a variety of patient-centered outcomes. This observational study examined the impact of dermoglandular pedicle type on subjective postoperative nipple sensation. METHODS: A total of 178 women who underwent a bilateral reduction mammoplasty at a single institution from 2017 to 2023 and completed an 11-item survey assessing subjective postoperative nipple sensitivity across various tactile modalities were included. Patient-reported nipple sensations were compared across pedicle type and subgrouped by resection volume. RESULTS: Of the included survey respondents, 72% (128) underwent reduction with an inferior pedicle and 28% (50) with a superior or superomedial pedicle. Over 92% of patients reported the preservation of postoperative nipple sensation. Compared to the inferior pedicle, the superior pedicle cohort reported decreased nipple sensitivity to light touch (56% vs 30%, respectively) and temperature (30% vs 15%). In resection weights greater than 500 grams, the superior pedicle cohort was less satisfied with postoperative nipple sensation (84% vs. 58%), reported decreased sensation in light touch (58% vs 24%), pressure (50% vs 21%), and experienced more numbness and tingling (17% vs 1.4%) (all p-values ≤0.05). CONCLUSION: The majority of patients maintain some sensation after reduction mammoplasty; however, approximately 10% reported a relative decrease in subjective nipple sensation. Pedicle choice did not significantly affect sensory recovery in resection weights of less than 500 grams. When a greater resection weight is anticipated, the inferior pedicle may be associated with more favorable nipple sensation outcomes.

The impact of age on outcomes after breast reduction surgery - A multi-institutional data analysis of 40,958 cases.

BACKGROUND: Reduction mammoplasty is popular among people of various age groups, yet the impact of age on postoperative outcomes remains debated. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (2008-2021) was queried to identify adult female patients who underwent reduction mammoplasty. Patients were categorized into 10-year age brackets (i.e., 18-29, 30-39, 40-49, 50-59, 60-69, and >70 years). We compared age-dependent 30-day outcomes via confounder-adjusted multivariate analyses. RESULTS: 40,958 female patients (mean age: 41 ± 14 years and mean body mass index: 31 ± 6.1 kg/m²) were identified. Complications occurred in 6.4% (n = 2635) of cases, with 770 (1.9%) and 483 (1.2%) patients requiring reoperation and readmission, respectively. 1706 (4.2%) women experienced surgical complications, whereas medical complications were generally rare (n = 289; 0.7%). Compared with women aged 18-29 years, risks of any, surgical, and medical complications were higher for patients aged 30-39 years (OR: 1.22, p < 0.01; OR: 1.05, p = 0.51; OR: 1.84, p < 0.01), 40-49 years (OR: 1.34, p < 0.01; OR: 1.17, p = 0.04; OR: 1.54, p = 0.03), 50-59 years (OR: 1.45, p < 0.01; OR: 1.31, p < 0.01; OR: 1.78, p < 0.01), 60-69 years (OR: 1.38 years, p < 0.01; OR: 1.29, p = 0.01; OR: 1.71, p < 0.01), and >70 years (OR: 1.25, p = 0.18; OR: 1.01, p = 0.98; OR: 1.86, p = 0.14). Patients aged >30 years were also more likely to require readmissions and reoperations. CONCLUSION: Patient age significantly affects outcomes after reduction mammoplasty, with the lowest risk in patients aged <30 years. Importantly, the association between age and postoperative morbidity was not linear. These findings can help guide informed decisions, recognizing that while age is a factor, it is not the sole determinant of risk.

Breast Reduction Epidemiology and Complications in Nonbinary, Transgender, and Cisgender Adults.

INTRODUCTION: Research in gender-affirming chest surgery has primarily compared cisgender versus transgender and gender-diverse (TGD) people, without specifically addressing nonbinary people. This study will assess surgical complications between cisgender, transgender, and nonbinary adults undergoing breast reductions. METHODS: The National Surgical Quality Improvement Program databases from 2015 to 2021 were used to identify TGD patients who underwent breast reduction (Current Procedural Terminology code: 19318) and cisgender patients who underwent this procedure for cosmesis or cancer prophylaxis. Analysis of variance tests, chi-squared tests, unpaired t-tests, and regression models compared complications among cisgender, transgender, and nonbinary patients. RESULTS: A total of 1222 patients met the inclusion criteria: 380 (31.1%) were cisgender, 769 (62.9%) were transgender, and 73 (6.0%) were nonbinary. The proportion of TGD patients grew significantly relative to cisgender patients over the study period (P < 0.001). The overall all-cause complication rate was 3.4%, with 4.2% of cisgender, 1.4% of nonbinary, and 3.1% of transgender patients experiencing surgical complications. After adjusting for confounding variables, no statistically significant difference was observed in all-cause complication rates between the cohorts. In the sample, 19 transgender patients (2.5%) underwent reoperation. Transgender patients had a lower likelihood of wound complications (odds ratio: 0.172; 95% confidence interval: 0.035-0.849; P = 0.031) compared to cisgender patients and nonbinary patients. None of the patients experienced a severe systemic complication. CONCLUSIONS: The findings emphasize the growing demand and safety of gender-affirming breast reductions. They underscore the importance of continued research and tailored approaches to delivering care to nonbinary and transgender patients, addressing their diverse needs and improving access to gender-affirming surgeries.

Reduction Mammoplasties: Risk Factors and Early Complications-About 1442 Cases.

BACKGROUND: Breast reduction surgery is a widely performed plastic surgery procedure. The incidence of such complications has been steadily decreasing in recent years but is still nonetheless 5.6%. The primary aim of this study was to analyze the incidence of the main postoperative complications of breast reduction surgery. In addition, we identified cause-and-effect links between complications and characteristics of the patients, such as smoking, age, weight resection, BMI, and wound drainage. MATERIALS AND METHODS: This retrospective study was performed on a population of 1442 women who underwent breast reduction surgery between January 2016 and October 2022 in the plastic surgery unit at Saint-Louis Hospital, Paris, France. At the follow-up examination, we evaluated the patients for complications. RESULTS: The average resection weight was 1297.7 g in a population for which the average BMI was 28.9. We found 19.9% rate of total complications, of which 3.5% were major complications. We found that only the resection weight was a risk factor for complications. DISCUSSION: The main strength of our study is the size of our sample. The large number of patients allowed us to conduct numerous analyses and obtain significant results despite the rarity of certain events. This large cohort was also responsible for the high statistical power of our results. CONCLUSION: The risk of developing a postoperative infection was 7.5% for resections of less than 2.4 kg, increasing to 13.9 % when greater than that. Thus, the administration of prophylactic antibiotic therapy to affected women to reduce the risk of infection is a distinct consideration. For the other factors, while none of them appeared to promote the occurrence of adverse events and, therefore, do not formally contraindicate breast reduction surgery, some preventive measures still strike us as being relevant, such as blade drainage, weight loss, diabetes control, and smoking cessation.

Topographic Analysis of the Nipple-Areolar Complex Sensation in Superomedial Pedicle Breast Reduction.

BACKGROUND: Surgeons meticulously perform breast reductions, while ensuring vascular integrity of the pedicle and Nipple-Areolar complex (NAC) to prevent any complication. It is crucial to remember that loss of sensation is also substantial complication, mainly due to unique characteristic features of the NAC. This study aimed to compare early and long-term sensory results by performing topographic analysis of NAC sensation after superomedial pedicle breast reduction. METHODS: A prospective study was conducted by including nonrandomized female patients who underwent breast reduction surgery with wise pattern excision superomedial pedicle technique between January 2019 and June 2022. Semmes-Weinstein Monofilament (SWM) test performed at preoperatively, 3-6 months and 15-18 months postoperatively. NAC complex was divided into four equal quadrants and nipple: superomedial (SM), inferomedial (IM), inferolateral (IL), superolateral (SL) and Nipple (N). Touch-Test® Sensory Evaluator Chart was used to evaluate sensory results. RESULTS: None of the patients had any loss of sensation during preoperative SWM test. In postoperative 3-6 months, statistically significant differences were observed between N and SL (p = 0.002), SL and IM (p < 0.05), SM and IM (p < 0.05). In postoperative 15-18 months, there was no difference between the quadrants and nipple (p = 0.07). In early and long-term comparisons of the same quadrants, IL less pronounced than other quadrant comparisons (p = 0.034). A statistical difference was observed in overall NAC score (p < 0.05). CONCLUSIONS: It would be beneficial to inform patients overall NAC sensation in the postoperative may not be as good as preoperative, there might be variations in NAC sensation across different quadrants in early period.

Assessment of risk factors for postoperative complications of breast reduction by superior or superomedial pedicle.

BACKGROUND: Some risk factors for breast reduction complications are well known but for others the results are contradictory in scientific literature. The choice between superior pedicle and superomedial pedicle as a risk factor has been rarely studied. We aim to better identify the risk factors for breast reduction complications, including the choice between these two pedicles, in order to better prevent their occurrence. METHODS: We performed a retrospective analysis of the medical records of patients who underwent a bilateral breast reduction from august 2020 to august 2023 in our center. Patient data were obtained and correlated with postoperative complications using statistical tests and a literature search was carried out to compare our results to the current evidence. RESULTS: We included 216 patients. The complication rate was 24.07%. The most frequent complication was wound dehiscence (17.59%), followed by partial Nipple-Areola-Complex necrosis or peroperative suffering requiring conversion to Nipple-Areola-Complex free graft (5.56%). Increased Body Mass Index, superomedial pedicle and resection weight ≥650g were associated with an increased probability of complication occurrence (P=0.048, P=0.005 and P=0.044). The superomedial pedicle and the resection weight ≥650g were associated with an increased probability of wound dehiscence (P=0.005 and P=0.037). The difference between the preoperative and the postoperative Sternal-Notch-Nipple distance was associated with an increased probability of partial Nipple-Areola-Complex necrosis or Nipple-Areola-Complex free graft (P=0.014). CONCLUSION: Correcting modifiable preoperative risk factors and mastering both techniques, enabling the surgeon to choose the one best suited to each patient's clinical situation, reduces the complication rate.

[Comparison of breastfeeding duration in women before and after breast reduction surgery]. / Comparaison de la durée d'allaitement maternel chez les femmes avant et après mammoplastie de réduction.

BACKGROUND: Breast reduction surgery often concern women of childbearing age. However, it can interfere with the ability to breastfeed, whereas the benefits of breastfeeding are well known. Current data in the literature do not provide precise information on the possibilities of breastfeeding after breast reduction surgery. OBJECTIVES: The aim of this study was to assess long-term breastfeeding ability of women after breast reduction performed in our centre. METHODS: This is a retrospective comparative study including patients treated with breast reduction at Saint-Louis Hospital between 2010 and 2017 and who have had children before or after surgery. Operative details were retrieved from medical records and ability to breastfeed was assessed during a phone interview. Breastfeeding before surgery was compared to breastfeeding after surgery. RESULTS: We analysed 21 births before and 35 births after breast reduction. Breastfeeding initiation was similar in the two groups (90% vs. 83%, P=0.7), but the median duration was significantly shorter after breast reduction compared with before (3 weeks vs. 10 weeks; P<0.01), the rate of breastfed child at 3 months was lower after surgery (11% vs. 43%; P<0.01), the use of infant formula was higher after surgery (100% vs. 74%, P<0.01), and we found a higher rate of discontinuation caused by hypogalactia (69% vs. 11%; P<0.001). CONCLUSION: Breastfeeding is possible but more difficult to sustain over time after breast reduction. Patients need to be made aware of that before surgery, and patients who still want to breastfeed should be encouraged at the maternity.

Application of Liposuction and Superior Pedicle Vertical Mammoplasty for Severe Breast Hypertrophy.

BACKGROUND: Vertical mammoplasty techniques have been widely used for breast reduction. The authors present the combination of superior pedicle vertical mammoplasty with liposuction in different regions in the treatment of severe breast hypertrophy in obese patients. We also propose some innovative methods in terms of surgical approach, breast parenchymal anatomy pattern and liposuction. METHODS: A retrospective study of 50 female patients with severe hypertrophic breasts and obesity who underwent breast reduction in our department from February 2019 to February 2022 was performed. Pre- and postoperative photographs, breast parenchyma distribution and postoperative patient satisfaction were recorded. RESULTS: Fifty patients underwent breast reduction. Through clinical examination, patient photo evaluation and satisfaction survey results. Good breast shape and projection, full upper pole of the breast, and high satisfaction results were obtained. There were no serious complications. CONCLUSION: This technique is acceptable and reproducible. It is suitable for patients with varying degrees of breast hypertrophy, especially those with severe hypertrophic breasts and obesity. There are fewer associated complications and a lower rate of re-repair. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.

Oncoplastic surgery in the USA: a review of where we started, where we are today and where we are headed.

The surgical management of breast cancer has evolved tremendously over the last century and now includes oncoplastic techniques that improve both cosmetic and oncologic outcomes for patients. The purpose of this review is to provide the reader with a broad overview of the history of oncoplastic breast surgery in the United States (USA), and to summarize important patient factors and technical innovations for optimal operative planning in the era of multimodal treatment of breast cancer. The indications for oncoplastic surgery (OPS) have broadened significantly as more women pursue breast conservation with preservation of their native breast tissue. The operative philosophy of OPS is based on fundamental reconstructive principles, with technique selection based largely on tumor size and location. Reduction mammoplasty and mastopexy techniques have become some of the most utilized procedures in OPS due to their versatility to address tumors in almost all areas of the breast. Volume replacement techniques with locoregional perforator flaps continue to gain popularity as a single-stage reconstructive option for women with large tumor to breast ratios, especially with specialized plastic surgeons at high volume, academic centers. The oncologic advantages of OPS have allowed women to avoid mastectomy with improved margin control, re-excision rates, and equivalent overall survival all while preserving the aesthetic outcomes for these patients. Despite the proven benefits of OPS, numerous healthcare systems barriers including insurance status, geographic location, referral patterns, and racial disparities all continue to play a role in access to surgical sub-specialized breast oncology care demonstrating the need for ongoing research and education about oncoplastic principles.

The Modified Superomedial Pedicle Breast Reduction Technique for Cases with SN-N Distance Exceeding 33 cm.

BACKGROUND: Symptomatic breast hypertrophy affects the quality of life of a large number of women globally. Many reduction mammoplasty techniques have been described for patients with breast hypertrophy. The aim of this study was to provide our clinic's experience in utilizing the modified superomedial pedicle breast reduction technique in specific patients suffering from breast hypertrophy, with sternal notch-to-nipple distance of more than 33 cm. METHOD: Our study included twenty patients who underwent, from January 2022 to December 2023, the modified superomedial pedicle breast reduction technique due to symptomatic breast hypertrophy with sternal notch-to-nipple distance of more than 33 cm in the Plastic and Reconstructive Surgery Department at Nicosia General Hospital in Cyprus. Patient demographics, comorbidities, pre- and postoperative breast anthropometric measurements and surgical complications were recorded and analyzed. RESULTS: The average age at the time of the reduction was 48 years. The mean preoperative body mass index was 28.52 kg/m2. Patients' comorbidities included one (5%) patient with diabetes, seven (35%) with obesity and three (15%) with hypertension. The mean preoperative sternal notch-to-nipple distance was 35.25 cm for the right breast and 34.90 cm for the left breast, while the mean postoperative was 20.65 cm for both breasts. The total mean resection weight of both breasts was 1643.45 g. Surgical complications were minor including two (10%) cases of local hematoma and one (5%) case of T-Junction wound breakdown. All patients were relieved from their preoperative symptoms and were satisfied with the final result. CONCLUSION: Our modified superomedial pedicle technique is a safe, effective and versatile pedicle to be used with many advantages, in specific patients suffering from breast hypertrophy with sternal notch-to-nipple distance of more than 33 cm, including its shape and rotational abilities, viability of the nipple and excellent outcome of glandular plication and breast reshaping.

Successful breastfeeding after breast reduction surgery or mastopexy: A retrospective comparative study.

Breastfeeding has been widely encouraged by health care systems for many years. Breast reduction or mastopexy, are very frequent procedures often performed on young women. The main objective of this study is to evaluate the impact of breast surgery on breastfeeding by comparing the success rate of breastfeeding in operated women versus unoperated women. Secondary objectives are to evaluate the breastfeeding success rate according to the surgical technique or the weight resected. A retrospective comparative study was conducted. Women of childbearing age who underwent breast reduction surgery or mastopexy at Henri-Mondor Hospital were contacted to answer a questionnaire about their pregnancies. Two hundred nine patients answered and two groups of patients were constituted, a preoperative group of 104 women who had a pregnancy before surgery and a postoperative group formed by 61 women who had a pregnancy after surgery. Breastfeeding success rate was 82% in the preoperative group versus 41% in the postoperative group. A statistically significant difference was found on the success rate of breastfeeding, as well as the rate of exclusive breastfeeding, with significantly lower rates in the postoperative group. In contrast, there was no significant difference between the different pedicles used, neither according to the weight of the resected gland. The cause of failure in the postoperative group was in most cases insufficient milk. Breast reduction surgery or mastopexy seems to have negative impact on the ability of operated women to breastfeed. This impact is multifactorial so these results should be interpreted with caution and further studies are needed to improve the management of these patients.

Effect of pedicle type on breast reduction: Clinical and patient-reported outcomes.

PURPOSE: The choice of pedicle in reduction mammaplasty is highly variable with prior studies demonstrating high patient satisfaction in most cases. This study aimed to examine the impact of pedicle type on clinical and patient-reported outcomes in patients undergoing reduction mammaplasty. METHODS: A total of 588 patients underwent bilateral reduction mammaplasty with Wise pattern or modified Robertson incision by 13 surgeons at a single institution. Clinical outcomes were compared according to the pedicle type in all patients and BREAST-Q responders (32% response rate). Survey respondents were sub-grouped by resection volume, and the BREAST-Q satisfaction scores were compared. RESULTS: Among all included reduction mammoplasties, 439 (75%) were performed using inferior pedicles, and 149 (25%) using superior or superomedial pedicles. Responders and non-responders were similar in preoperative characteristics including age, body measurements, and comorbidities. Although a higher incidence of infection occurred among the responders, clinical outcomes were comparable across all pedicle types. A total of 187 patients completed the BREAST-Q. Compared to the superior pedicle group, respondents in the inferior pedicle group reported higher nipple satisfaction, even when adjusted for resection weight over 500 g. In contrast, the superior pedicle group had better sexual well-being scores, which persisted in resection weight less than 500 g (all p values <0.05). CONCLUSION: Inferior pedicles were associated with greater nipple satisfaction and superior pedicles were associated with greater sexual satisfaction. Our findings suggest that those with resections less than 500 g were more satisfied with superior pedicles whereas those with greater resections were more satisfied with inferior pedicles.

Breast Reduction with Implants or Augmentation Reduction: Patient-Reported Outcomes from a Single-Centre Retrospective Cohort Analysis.

Background and Objectives: The correction of breast hypertrophy and ptosis with implant placement has always posed a challenge for plastic surgeons. Various methods have been devised, yielding conflicting results. The purpose of this study is to describe our surgical technique of breast reduction with silicone implants, present the safety profile of the procedure, and report patient-reported outcomes. Materials and Methods: A retrospective review was performed on our case series of cosmetic breast surgery performed by the senior author between October 2020 and November 2023. Only patients who had over 300 g of breast tissue removed were included. The surgery and demographic characteristics were recorded. Patients were asked to complete a questionnaire about satisfaction with their breasts pre-operatively and after the surgery. Results: Over 745 cases were performed, and 25 were included in the analysis. In total, 78.3% of the patients presented with a Grade 3 ptosis. The mean implant size was 352.39 cc (range 300-455 cc). The breast tissue removed ranged from 312 to 657 g. The mean follow-up was 14.17 months. Only one case required revision surgery after developing capsular contracture and a waterfall deformity. Patients reported a statistically significant improvement across all domains of the questionnaire (p < 0.001). Conclusions: Breast reduction plus implants is a safe and effective alternative for patients with large ptotic breasts who wish to attain a full upper pole. It carries a similar risk profile to augmentation mastopexy and maintains its functional benefits in alleviating back, neck, and shoulder pain.

Breast Vascularization and Its Implication in Breast Reduction and Mastopexy Surgery: Anatomical Study.

(1) Background: Breast reduction is one of the most frequently performed plastic surgeries in women worldwide. The Wise pattern breast reduction is one of the most frequent skin designs for this surgery. One key point of the surgery is to preserve a well-vascularized NAC by using different surgical pedicles. This study aims to test and update the anatomical knowledge of breast vascularization, the topographic and anatomical basis of the different surgical vascular pedicles, and the differences between the right and left sides. (2) Methods: A descriptive observational anatomical study was carried out on 15 breasts from 10 cryopreserved body donors. A dissection was performed by quadrants to know the affected arteries' origin in the different patterns. (3) Results: The largest and most frequently dissected internal mammary perforator artery was in the second intercostal space. A total of 44.9% of the dissected perforators are located in the upper inner quadrant, compared to 53.5% in the lower quadrants. (4) Conclusions: The upper inner quadrant alone has the most arterial perforators. In contrast, the sum of the two lower quadrants represents the greatest vascularization of the breast, with a small difference between both.

The articulated dual-supply pedicle for reduction mammoplasty.

Breast reduction surgery achieves symptomatic relief and improved quality of life for patients with excessive breast enlargement. Reduction mammoplasty has evolved over the last century with the introduction of multiple new pedicles and skin excision patterns utilizing the ample blood supply of the breasts. The superior pedicle is a relatively safe technique in small resections, while the superomedial pedicle, supplied by the internal mammary perforators, serves as a proper alternative in broader resections. We aim to introduce the dual-supply pedicle technique, taking advantage of the two efficient workhorse pedicles-the superior and superomedial. A retrospective study of 48 bilateral reduction mammoplasty patients operated over a 2-year period between 2017 and 2019 by a single surgeon (Y.W). Patient characteristics and postoperative outcome data were collected and evaluated. The novel surgical technique showed compatibility with different types of patients and breasts, forming excellent aesthetic outcomes. Complication rates were comparable or lower than previously published series. Major complications requiring revision surgery were encountered in 2 patients (2.08%) and minor complications in 11 patients (11.5%); 4 moderate surgical wound dehiscence, 6 minor surgical wound dehiscence and 1 fat necrosis. The Dual-Supply Pedicle Reduction Mammoplasty is a safe, reproducible technique, with a short learning curve, excellent aesthetical results, and an acceptable complication rate. Level of Evidence is Level III.

No drains in reduction mammaplasty - a systematic review.

Breast reduction mammaplasty is the only effective therapeutic intervention for patients with symptomatic breast hypertrophy. In this procedure, closed suction drains have become a standard of care, while the literature supporting use of drains is lacking. In fact, with emerging data we found out that drains might not be so necessary. This review aimed to systematically compare the number of complications in drained and undrained breasts and to evaluate the safety of omitting drains in reduction mammaplasty in clinical practice. A systematic review of literature was conducted identifying all studies on drainage in reduction mammaplasty. The analysed databases revealed 13 eligible studies to be included in this review. There were 308 drained breasts and 859 undrained breasts in total in patients from 16 to 73 years of age. The resected tissue weight per side fluctuated from 108 to 1,296 grams. In total, there was only 2.4% incidence of haematoma complications in undrained breasts and 3.9% in drained breasts. Closed suction drains are still being routinely used in reduction mammaplasty, although aborting drain use is proven to be not only safe, but advantageous. The clear benefit is increased patient comfort, shortened hospital stay, decreased cost of the procedure and nurse care, and decreased rate of complications.

The Impact of Higher BMI on Wound Complications Following Adolescent Breast Reduction: A Retrospective Study of 1215 Cases.

BACKGROUND: Macromastia is a physically and psychologically distressing condition for adolescents. While reduction mammaplasty is often the best treatment, risk factors for adolescent wound complications remain unclear. This study aims to investigate the impact of obesity and other predictors of postoperative wound complications following adolescent reduction mammaplasty using a national database. METHODS: The 2012-2019 National Surgical Quality Improvement Program Pediatric (NSQIP-P) databases were reviewed to identify primary reduction mammaplasty encounters. World Health Organization Body Mass Index (BMI), alongside patient and case characteristics, were assessed for association for 30-day wound disruption or surgical site complications. Statistical analyses were performed to identify independent predictors for complications and determine a potential BMI cutoff for risk stratification. RESULTS: There were 1215 patients with an average age of 16.6 years. The average BMI was 30.7 kg/m2, and 593 (48.8%) patients were nonobese while 622 (51.2%) were obese. The incidence of complications was 5.27%. Independent predictors of complications included a BMI 35-39.9, BMI > 40, and an American Society of Anesthesiologists (ASA) Classification > 3. A receiver operating characteristic curve determined that a BMI of 34.6 can be a potential cutoff for increased complication risk. CONCLUSIONS: Higher obesity increases risk of wound complications; however, complication rates remain low. A BMI of 34.6 is a potential screening metric for counseling and monitoring patients. Reduction mammaplasty should remain a viable option as it can significantly improve quality of life.
