Resection Weight Formulas for Reduction Mammoplasty: A Systematic Review and Regression Analysis.

Estimating resection weight for patients undergoing reduction mammoplasty (RM) informs surgical planning and outcomes. Existing formulas have limitations that make insurance coverage and accurate surgical planning challenging. We identified the most commonly used scales to evaluate their accuracy in estimating resection weight by applying them to a database of patients to compare calculated and actual resection weights. A database search was conducted using combinations of relevant terms. A regression analysis was conducted using formulas with strong R2 values (0.72-0.93) on a cohort of 1128 RM patients at a single institution. A total of 570 articles were identified. Fourteen manuscripts (n = 2232 patients [3320 breasts]) were ultimately included for review. Data on incisional patterns, pedicle supply, and breast measurements, such as sternal notch to nipple distance (n = 8 [57.1%]) or nipple to inframammary fold distance (n = 5 [35.7%]), were recorded. R2 values in our cohort (>500 g, n = 891; <500 g, n = 237) were calculated via regression analyses with five formulas: Appel (0.391 vs 0.146), Boukovalas (0.3552 vs 0.043), Descamps (0.391 vs 0.238), Eder (0.328 vs 0.114), and Kocak (0.3283 vs R2 indeterminate). Our analysis suggests that formulas reporting strong R2 values may have resulted from tailoring to surgeons' technique. Variation between cohorts is inevitable; however, we expect reliable results given our large sample. It is reasonable to conclude that existing formulas are not accurate representations of resection weights and thus are unreliable for surgical planning.

The Effects of Systemic Tranexamic Acid Administration on Drainage Volume, Duration of Drain Placement, and Length of Hospital Stay in Skin- and Nipple-Sparing Mastectomies with Immediate Expander-Based Breast Reconstruction

Background: Skin- (SSM) and nipple-sparing (NSM) mastectomies are frequently performed surgeries with a considerable risk for post-operative hematoma or seroma. Tranexamic acid (TXA) is a potent antifibrinolytic drug commonly used in many surgical fields but rather novel in plastic and, specifically, breast surgery. This study investigates the influence of TXA in patients undergoing SSM or NSM with expander-based reconstruction (EbR) on post-operative outcomes. Methodology: A retrospective study was conducted on 132 patients undergoing uni- or bilateral SSM or NSM with EbR between May 2015 and March 2022. Patients receiving systemic TXA treatment for 48 h following a standardized protocol were compared to those who received no treatment. Multivariable linear regression was performed to identify influencing factors and quantify their effect on drainage volume, duration of drain placement, length of hospital stay, post-operative bleeding, and seroma formation. Results: The 132 patients underwent a total of 155 mastectomies (72 in the TXA group, 83 in the control group). TXA significantly reduced drainage volume (−22.3 mL, p = 0.011). Duration of drain placement and length of hospital stay were significantly shorter in the TXA group (p &lt; 0.001 and p = 0.001). No significant side effects were reported. Conclusion: TXA is a safe drug if administered respecting the well-defined contraindications. Systemic TXA administration significantly reduces drainage volume in patients undergoing SSM or NSM and should encourage surgeons to reconsider using drains in post-operative protocols. Duration of drain placement and length of hospital stay were significantly reduced in the TXA group but other factors like resection weight might have a more substantial impact.

Seasonal Impact on Wound Healing and Surgical Site Infections after Reduction Mammoplasty.

Background: The incidence of reduction mammoplasty has been steadily increasing over recent decades. Surgical site infections (SSIs) represent a common yet preventable complication across surgical disciplines. Studies across various surgical specialties have indicated a seasonal influence on SSIs, primarily correlated with higher temperatures and humidity. However, there remains a scarcity of clear data regarding the seasonal effects on complications specifically in breast surgery. Methods: We conducted a retrospective review encompassing all patients who underwent primary bilateral reduction mammoplasties at our institution between 1 June 2016, and 1 September 2019. The data collected included patient demographics, surgical details, and postoperative complications. The rates of SSIs and wound healing disturbances (WHDs) were correlated with local meteorological data at the time of surgery. Results: A total of 808 patients (1616 breasts) met the inclusion criteria. The mean age was 41 ± 14.8 years, with a mean BMI of 28.9 ± 5.2 kg/m2 and a mean follow-up duration of 8.9 ± 9.8 months. Nineteen cases (2.35%) of surgical site infections and 77 cases (9.52%) of wound healing disturbances were reported. No statistically significant increase in the risk of SSIs (p = 0.928) or WHDs (p = 0.078) was observed during the warmer months of the year. Although no specific risk factors were identified for surgical site infections, both resection weight (p < 0.001) and diabetes mellitus (p = 0.001) demonstrated increased risks for wound healing disturbances. Conclusions: While seasonal temperature variations have been shown to impact SSIs and WHDs in body contouring procedures, our findings suggest that breast reduction surgery may not be similarly affected.

The “Mosque Tower Pattern” for the Preoperative Marking of Reduction Mammaplasty

Background: Breast reduction, the seventh most performed plastic surgery globally, has witnessed a significant increase in procedures over recent years. Various techniques exist, each with its advantages and complications, emphasizing the critical role of preoperative marking. Although existing literature focuses on different reduction mammaplasty techniques, limited attention is given to surgical preoperative marking. This study introduces a “mosque tower” pattern combined with a superomedial pedicle, aiming to minimize complications and standardize the design based on individualized factors such as patient characteristics and predicted breast reduction weight. Methods: The retrospective case series includes 103 women who underwent reduction mammaplasty between 2017 and 2020. Surgical marking is described, and complications are recorded. The study categorizes breasts into three groups based on key-hole dimensions, correlating them with predicted resection weight. Statistical analysis establishes a rationale formula for selecting key-hole size. Results: A total of 175 breasts were reduced in 103 women with an average follow-up of 29.8 months. The mean resection weight was 883 g per breast (range: 490–2531). A complication rate of 8% was observed, with only 2.8% experiencing wound breakdown, notably lower than reported rates in other studies. Key-hole dimension as a predicting variable was correlated significantly with resection weight. Conclusions: The mosque tower pattern proves to be an effective, safe, and reproducible method for preoperative marking in reduction mammaplasty. The study emphasizes the importance of individualized planning to achieve satisfactory results, particularly for surgeons in their early practice.

Modified McKissock Technique for Secondary Breast Reduction - A Prospective Study on Safety, Surgical and Aesthetic Outcomes.

Numbers of secondary breast reductions are increasing but those are potentially associated with higher complication rates than primary mammaplasty. Necrosis of the Nipple-Areola-Complex (NAC) is a devastating complication that can occur after repeated NAC transposition, particularly when the initially used pedicle is unknown. Thus, the authors established a modification of McKissock's technique for secondary breast reductions including three pedicle components to ensure safe vascular supply of the NAC. The presented technique incorporates a superior and inferior dermoglandular pedicle according to McKissock and an additional central pedicle. The technique was applied for secondary breast reduction in a series of 25 breasts (14 patients: 11 bilateral, 3 unilateral). Complication rates, pre- and postoperative BREAST-Q scores, and aesthetic outcomes were evaluated. Mean resection weight was 299 g (range, 40-646), and the NAC was transposed by 4.2 cm on average (range, 1-10). No case of NAC-necrosis was observed, and comparison of pre- and postoperative BREAST-Q values indicated substantial improvement in all domains. Postoperatively, 84.6% of patients reported excellent satisfaction with breast appearance. According to those results, the modified McKissock-technique is a safe technique for patients requiring secondary breast reduction, even if the primarily used pedicle is unknown. Additionally, the established technique is associated with improved postoperative patient-reported outcomes and yields aesthetically favorable results.

Pressure makes diamonds? The impact of closed incision negative pressure wound therapy on complications following abdominoplasty in patients with massive weight loss—results from a case controlled trial

BackgroundThe effectiveness of closed incision negative pressure wound therapy (ciNPWT) has been shown across various studies. However, studies with large patient cohorts comprising post-bariatric patient populations are missing. The objective of this research was to assess the influence of ciNPWT on post-operative wound complications in this demanding patient collective. MethodsWe conducted a retrospective case-control study. Between 1 January 2013 and 31 December 2023, a total of 251 abdominoplasty procedures following massive weight loss were identified. Patients were matched based on resection weights. We matched 118 patients separated into two groups depending on post-surgical wound management (conventional wound dressings vs ciNPWT). The primary outcomes were wound-related disorders and secondary outcomes were the number of readmissions or reoperations within 30 days after the initial surgery. ResultsThe study revealed equal incidence of seroma formation (15 vs 15, p = 1.0), rates of wound dehiscence (23 vs 20, p = 0.56), surgical site infection (11 vs 6, p = 0.18), hematoma (17 vs 9, p = 0.07), complete removal of all drainages (6.7 vs 6.1 days, p = 0.34) and total number of readmission (12 vs 11, p = 0.77) or reoperations (12 vs 10, p = 0.63) within 30 days. The second hospital stay caused by revision was significantly shorter in the ciNPWT group (5.8 days vs 12.0 days, p = 0.02). ConclusionConsequently, we did not find evidence to support the hypothesis that ciNPWT reduces complications after abdominoplasty in patients with massive weight loss.

Efficacy of robot-assisted partial nephrectomy compared to conventional laparoscopic partial nephrectomy for completely endophytic renal tumor: a multicenter, prospective study

BackgroundThis study aimed to compare the efficacy of robot-assisted partial nephrectomy for completely endophytic renal tumors with the reported outcomes of conventional laparoscopic partial nephrectomy and investigate the transition of renal function after robot-assisted partial nephrectomy.MethodsWe conducted a prospective, multicenter, single-arm, open-label trial across 17 academic centers in Japan. Patients with endophytic renal tumors classified as cT1, cN0, cM0 were included and underwent robot-assisted partial nephrectomy. We defined two primary outcomes to assess functional and oncological aspects of the procedure, which were represented by the warm ischemic time and positive surgical margin, respectively. Comparisons were made using control values previously reported in laparoscopic partial nephrectomy studies. In the historical control group, the warm ischemia time was 25.2, and the positive surgical margin was 13%.ResultsOur per-protocol analysis included 98 participants. The mean warm ischemic time was 20.3 min (99% confidence interval 18.3–22.3; p < 0.0001 vs. 25.2). None of the 98 participants had a positive surgical margin (99% confidence interval 0–5.3%; p < 0.0001 vs. 13.0%). The renal function ratio of eGFR before and after protocol treatment multiplied by splits was 0.70 (95% confidence interval: 0.66–0.75). Factors such as preoperative eGFR, resected weight, and warm ischemic time influenced the functional loss of the partially nephrectomized kidney after robot-assisted partial nephrectomy.ConclusionsRobot-assisted partial nephrectomy for completely endophytic renal tumors offers a shorter warm ischemia time and comparable positive surgical margin rate compared with conventional laparoscopic partial nephrectomy.

Surgical Technique Selection in the Management of Pediatric Gynecomastia.

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. 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. 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. 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.

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

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. 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. 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. 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. 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.

Vertical Scar Reduction Mammaplasty Using the Superomedial-Based Pedicle Technique in Gigantomastia.

Breast reduction surgery has witnessed significant advancements in recent years; however, it continues to pose challenges for both surgeons and patients when dealing with cases involving excessive breast volume and severe breast ptosis. This study aimed to assess the aesthetic outcomes and the impact on the quality of life, as measured by the BREAST-Q questionnaire, in patients with gigantomastia and severe breast ptosis who underwent reduction mammaplasty using the superomedial-based pedicle technique. We present a retrospective series comprising 84 patients who underwent reduction mammoplasty utilizing the superomedial pedicle technique. The surgical resections exceeded 1 kg per breast, with a mean resection weight of 1506.58 g (right breast) and 1500.32 g (left breast). The preoperative mean suprasternal notch to nipple distance measured 40.50 cm (right breast) and 40.38 cm (left breast). Postoperatively, the patients were followed up for a minimum of 6 months. Both preoperative and postoperative BREAST-Q surveys were administered to the participants, and scores were analyzed using descriptive statistics. Complications were observed in 3 patients (3.57%), characterized by partial loss of the areola, which resolved spontaneously over time. Additionally, 2 cases of hematoma and 2 instances of minor delayed wound healing were reported. All patients expressed satisfaction with their aesthetic outcomes, as they achieved a natural breast shape and minimal scarring, along with symptomatic relief. The superomedial pedicle reduction mammaplasty technique has demonstrated its ability to produce satisfactory aesthetic outcomes and long-term benefits in patients with excessively large breasts. Careful patient selection and postoperative management are vital for achieving optimal results. Further investigations involving larger sample sizes and longer follow-up periods are warranted to validate our findings. IV.

Risk Factors for Recurrent Laryngeal Nerve Palsy in Thyroid Surgery: A Single Center Experience of 1147 Procedures with Intermittent Intraoperative Neuromonitoring.

Recurrent laryngeal nerve (RLN) palsy is one possible complication during thyroid surgery. Intraoperative neuromonitoring and visualization of the nerve during surgery are standard procedures to reduce the risk of RLN palsy. This study aims to investigate new factors for RLN palsy and review ones that are already known in the literature to help surgeons prepare for the procedure. A retrospective study design was used to analyze the data of 1147 patients from a certified center for thyroid surgery. All patients underwent either total thyroidectomy or hemithyroidectomy from 2016 to 2020. The acquired information was analyzed descriptively. A logistic regression was used to analyze the independent variables of interest with the binary variable RLN palsy (yes/no). For the second aim of this study, a multiple logistic regression was applied to analyze the combined significant known and new risk factors. Surgery indication for Graves' disease (OR 14.34, p < 0.001), thyroid cancer (OR 2.39, p = 0.012), and recurrent goiter (OR 5.57, p < 0.001) increased the risk for RLN palsy significantly compared to nodular goiter in hemithyroidectomy. The duration of surgery correlated positively with a higher risk for RLN palsy (OR 1.009, p = 0.005). For gender, BMI, resection weight, left or right nerve at risk, and surgeon experience, no significant differences were found. Operations for Graves' disease, thyroid cancer, and recurrent goiter have the highest risk for RLN palsy and surgeons should be alerted. The longer the operation, the higher the risk of RLN palsy. The correlation between surgery method (hemithyroidectomy vs. thyroidectomy) and RLN palsy should be carefully considered due to possible bias.

Analysis of laboratory markers in body contouring procedures after bariatric surgery does not indicate particular risks for perioperative complications

BackgroundBody contouring surgery after massive weight loss is associated with different risk factors. Wound healing disorders and seromas commonly occur postoperatively. Bariatric interventions lead to massive weight loss with excess skin and soft tissue. In this study, perioperatively collected laboratory markers of this special patient population were analyzed.MethodsFifty-nine patients were analyzed retrospectively regarding bariatric surgery, weight loss, body contouring surgery, laboratory markers, and complication rates.ResultsBody contouring surgery (n = 117) was performed in 59 patients. Weight loss was achieved after gastric bypass (40.1%), gastric banding (33.9%), or sleeve gastrectomy (26.0%), with an average of 69.2 kg. The most common body contouring procedure included abdominoplasty (n = 50), followed by thigh lift (n = 29), mammaplasty (n = 19), brachioplasty (n = 14), and upper body lift (n = 5). Analysis of laboratory markers revealed no exceptional and clinically relevant variations. Correlation analysis revealed associations between resection weight, amount of drain fluid, and particular laboratory markers.ConclusionAnalysis of perioperative laboratory markers in this special patient population after massive weight loss did not indicate clinically relevant risk factors regardless of the type of bariatric or body contouring surgery. Body contouring surgeries after bariatric interventions prove to be safe and low risk concerning perioperative laboratory markers and postoperative hospitalization.

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

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. 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. 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. 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.

Gigantic Macromastia: Modified Superomedial Pedicle is a Good Solution

Abstract Background Reduction of very huge breast—gigantic macromastia—is a challenge to breast surgeons in choosing the right procedure to obtain an optimal outcome. The feasibility of a superomedial pedicle (SMP) with some modifications proves to be a good option to achieve a viable nipple areolar complex (NAC) with good size and shape after good resection above 800 g. Materials and Methods Out of the 35 patients with 70 breast reductions, 15 can be considered gigantic macromastia with reductions above 800 g. A retrospective analysis of 30 breast reductions in these 15 patients from 2010 to 2023 was done. All cases were done using SMP with some modifications. The sternal notch to the nipple, the new NAC site, pedicle length, resection weight, and complications were analyzed. The modifications followed were lowering the new NAC, narrowing the distance between medial and lateral pillar width, medializing the pedicle, and lengthening the vertical limb. Results There was no total necrosis of the NAC. Partial necrosis occurred in three patients that were managed conservatively and one case of fat necrosis needed debridement. All of them had a good size, shape, and form. Conclusion SMP is a versatile technique with flexibility to modify the dimensions to get a robust blood supply to the NAC, after obtaining an adequate resection.

Predicting Reduction Mammaplasty Total Resection Weight With Machine Learning.

Machine learning (ML) is a form of artificial intelligence that has been used to create better predictive models in medicine. Using ML algorithms, we sought to create a predictive model for breast resection weight based on anthropometric measurements. We analyzed 237 patients (474 individual breasts) who underwent reduction mammoplasty at our institution. Anthropometric variables included body surface area (BSA), body mass index, sternal notch-to-nipple (SN-N), and nipple-to-inframammary fold values. Four different ML algorithms (linear regression, ridge regression, support vector regression, and random forest regression) either including or excluding the Schnur Scale prediction for the same data were trained and tested on their ability to recognize the relationship between the anthropometric variables and total resection weights. Resection weight prediction accuracy for each model and the Schnur scale alone were evaluated based on using mean absolute error (MAE). In our cohort, mean age was 40.36 years. Most patients (71.61%) were African American. Mean BSA was 2.0 m 2 , mean body mass index was 33.045 kg/m 2 , mean SN-N was 35.0 cm, and mean nipple-to-inframammary fold was 16.0 cm. Mean SN-N was found to have the greatest variable importance. All 4 models made resection weight predictions with MAE lower than that of the Schnur Scale alone in both the training and testing datasets. Overall, the random forest regression model without Schnur scale weight had the lowest MAE at 186.20. Our ML resection weight prediction model represents an accurate and promising alternative to the Schnur Scale in the setting of reduction mammaplasty consultations.

The Modified Frailty Index Predicts Major Complications in Oncoplastic Reduction Mammoplasty

Background An important component of preoperative counseling and patient selection involves surgical risk stratification. There are many tools developed to predict surgical complications. The Modified Frailty Index (mFI) calculates risk based on the following five elements: hypertension, chronic obstructive pulmonary disease, congestive heart failure, diabetes, and functional status. Recent literature demonstrates the efficacy of the mFI across multiple surgical disciplines. We elected to investigate its utility in oncoplastic reductions (OCR). Methods A retrospective review of all patients with breast cancer who underwent OCR from 1998 to 2020 was queried from a prospectively maintained database. Patient demographics, comorbidities, and surgical details were reviewed. The mFI was computed for each patient. The primary clinical outcome was the development of complications. Results 547 patients were included in the study cohort. The average age was 55 and the average body mass index was 33.5. The overall complication rate was 19% (n = 105) and the major complication rate was 9% (n = 49). Higher frailty scores were significantly associated with the development of major complications (P &lt; 0.05). mFI scores of 0 had a major complication rate of 5.7%; scores of 1, 13%; and scores of 2, 15.1%. The relative risk of a major complication in patients with elevated mFI (&gt;0) was 2.2. Age, body mass index, and resection weights were not associated with complications (P = 0.15, P = 0.87, and P = 0.30 respectively) on continuous analysis. Conclusions Elevated mFI scores are associated with an increased major complication profile in patients who are undergoing OCR. Hypertension and diabetes are the most common comorbidities in our population, and this tool may assist with preoperative counseling and risk stratification. Benefits of this risk assessment tool include its ease of calculation and brevity. Our study is the first to demonstrate its utility in OCR; however, further study in high-risk patients would strengthen the applicability of this frailty index.

D28. Are Drains Protective in Greater Resection Weights? A Retrospective Cohort Study of 1,098 Reduction Mammoplasties Using the Superomedial Pedicle Wise-pattern Technique

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

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

Marijuana Use in Aesthetic Surgery Patients: A Retrospective Review of 441 Cases

Abstract Goals/Purpose Marijuana use is increasing in Canada following its legalization in 2018. 27% of Canadians were reported to have consumed marijuana in 2022. Marijuana use in surgical patients is a topic that has had exponential growth in the literature recently. The drug has many therapeutic effects such as analgesia, muscle relaxation, sedation and mood improvement. However, it is also associated with deleterious cardiovascular, respiratory and coagulopathic effects that can significantly impact the care of surgical patients in the peri-operative period. Literature from other surgical specialities has shown similar recovery and ultimate surgical outcome between marijuana users and non-marijuana users despite increased pain and poorer quality of life associated with marijuana use. There is a paucity of information about the effects of marijuana on aesthetic plastic surgery outcomes. The prevalence of marijuana use in aesthetic plastic surgery patients is currently unknown and there is a need for more evidence to develop clinical practice guidelines regarding the use of marijuana in the perioperative period. The purpose of this study is to describe the effects of marijuana consumption on aesthetic plastic surgery outcomes. Methods/Technique A single-center retrospective review was completed including all patients who underwent abdominoplasty, mastopexy and/or other body contouring surgery (such as brachioplasty, thigh lift or lower body lift) between January 2021 and August 2023. Other procedures such as liposuction, fat grafting, implant insertion or removal were also reviewed if they took place during the same general anesthetic. Marijuana use was defined as use within 4 weeks pre- and/or post-operatively. Data collection included patient demographics, body mass index (BMI), marijuana use, smoking status, comorbidities, surgical procedure(s) performed, operative time, resection weight and/or liposuction volume (if applicable), complications and follow up. Results/Complications A total of 1000 procedures in 441 patients were reviewed during the 32-month study period. Average patient age was 43 years old and average patient BMI was 27.3 kg/m2. 20.4% of patients were marijuana users. The average number of procedures completed per patient was 2.3 and average operative time was 167 minutes (2 hours and 47 minutes). 79% of cases involved more than one surgical procedure. 63% of the 441 cases involved an abdominoplasty, 49% involved a mastopexy, 5% involved a brachioplasty and 4% involved a thigh lift procedure. 33% of cases included breast implants and 47% liposuction. Average follow up time was 5.2 months. Overall surgical complications consisted of a 5% superficial infection rate, 1% deep infection rate, 9% seroma rate, 1% hematoma and lymphocele rates, 3% rate of wound dehiscence requiring surgical intervention and 11% rate of superficial delayed wound healing. There were no cases of nipple necrosis or full thickness skin necrosis. A comparison of patient demographics between marijuana and non-marijuana user groups revealed that marijuana users were significantly younger than non-marijuana users (average age 39 and 44 years old respectively). Surgical data, outcomes and complications were not found to be significantly different between the 2 groups for all variables. Conclusion Marijuana consumption in the perioperative period does not appear to affect aesthetic surgery outcomes such as post-operative infections, seroma, lymphocele, wound dehiscence, or fat necrosis based on the results of this study. There is a need for prospective work on this topic to produce better quality evidence and ultimately to create evidence-based guidelines on the perioperative use of marijuana for aesthetic surgery patients.

Efficacy and safety of a transaortic approach to midventricular and apical septal myectomy

ObjectiveThe study objective was to evaluate the safety and efficacy of a transaortic approach to midventricular and apical septal myectomy in patients with hypertrophic cardiomyopathy with left ventricular outflow tract or midventricular obstruction. MethodsFrom January 2018 to August 2023, 940 patients underwent transaortic septal myectomy at the Cleveland Clinic, of whom 682 (73%) had midventricular or apical resection. Patients who underwent isolated basal myectomies were excluded. Templated operative reports designated septal regions resected as basal (opposition to mitral valve up to the leaflet tips), midventricular (leaflet tips to just beyond the papillary muscle heads), and apical (apical third of the ventricle). Myocardial resection specimen weights, intraventricular gradients, and clinical outcomes were assessed. ResultsOf the 682 patients, 582 (85%) had basal plus midventricular resection and 78 (11%) had basal, midventricular, and apical resection. Mean preoperative intraventricular gradient was 102 ± 41 mm Hg. Median resection weight was 10 g (15th, 85th percentiles: 7, 15), and mean postoperative intraventricular gradient was 16 ± 10 mm Hg, with 625 (96%) patients achieving gradients 36 mm Hg or less. There were no iatrogenic mitral or aortic valve injuries. Permanent pacemaker placement was required in 38 patients (5.6%), of whom 8 (1.2%) had normal preoperative conduction. Operative mortality occurred in 1 patient (0.1%) after an intraoperative ventricular septal defect. ConclusionsMost patients undergoing septal myectomy for relief of obstruction required resection beyond the basal septum. With specialized instrumentation, detailed imaging and knowledge of variable septal anatomy, resecting midventricular and apical septal muscle can be safely and effectively achieved through a transaortic approach.
