Efficacy of the Modified 5-Item Frailty Index in Predicting Surgical-Site Infections in Patients Undergoing Breast Implant Augmentation: A National Surgical Quality Improvement Project-Based 5-Year Study

Background

The ability to predict breast implant augmentation complications can significantly inform patient management. A frailty measure, such as the modified 5-item frailty index (mFI-5), is becoming an increasingly established risk factor for adverse postoperative outcomes. The authors hypothesized that the mFI-5 is predictive of 30-day postoperative complications in breast augmentation.

Objectives

To investigate if mFI-5 can predict the likelihood and magnitude of 30-day complications resulting from breast augmentations.

Methods

A retrospective review study of the National Surgical Quality Improvement Program database for patients who underwent breast implant augmentation without other concurrent procedures, from 2015 to 2019. Age, BMI, number of major comorbidities, American Society of Anesthesiologists (ASA) classifications, smoking status, mFI-5 score, and modified Charlson comorbidity index score were compared as predictors of all-cause 30-day complications and 30-day surgical-site complications using regression analyses.

Results

Overall, 2478 patients were analyzed, and among them, 53 patients developed complications (2.14%). mFI-5 score significantly predicted surgical-site infection (SSI) complications (odds ratio [OR] = 4.24, P = .026). Frail patients had a higher occurrence of SSIs than nonfrail patients (P = .049). Multivariable analyses showed ASA class predicted 30-day SSI complications (OR = 5.77, P = .027) and mFI-5 approached, but did not reach full significance in predicting overall 30-day complications (OR = 3.14, P = .085).

Conclusions

To date, the impact of frailty on breast implant procedure outcomes has not been studied. Our analysis demonstrates that the mFI-5 is a significant predictor for SSIs in breast implant augmentation surgery and is associated with overall complications. By preoperatively identifying frail patients, the surgical team can better account for postoperative support to minimize the risk of complications.

Defining Cognitive Competencies for Breast Augmentation Surgery

BACKGROUND

Breast augmentation is the most performed aesthetic procedure in the United States yet one that surgical trainees have limited exposure to. This creates a lack of confidence in performing this key procedure among graduates. It is imperative to develop novel curricula and objective measures to standardize acquiring competency.

OBJECTIVE

This qualitative study establishes various cognitive competencies and pitfalls in augmentation mammoplasty.

METHODS

Using a priori established task analysis, literary sources and operative observations, a total of 20 cognitive vignettes were developed to conduct cognitive task analyses (CTA) for breast augmentation through semistructured interviews of experts. Interviews were itemized, and verbal data were recorded, transcribed verbatim, and thematically analyzed by reviewers.

RESULTS

Eight experts were interviewed (median age 39 years, 87.5% males, with a median of 7 years in practice). A conceptual framework for breast augmentation was developed and divided into 5 operative stages containing 208 competencies and 41 pitfalls. Pitfalls were mapped to deficits in shared decision making, proper informed consent, prospective hemostasis, and awareness of anatomical landmarks and markings.

CONCLUSIONS

This work provided an inclusive framework of cognitive competencies in breast augmentation surgery to facilitate their assessment. This model guides the analysis of other procedures to transfer cognitive competencies to learners. In a transition toward competency-based education, this provides a primer to assessments that include all aspects of a surgeon's skill set.

Teaching and Assessing Cognitive Competencies in Aesthetic and Plastic Surgery

BACKGROUND

Cognition, part of surgical competence, employs forward planning, error prevention, and orchestrating technical skills. Thus, an understanding of mental processes used by experts throughout patient care is essential to teaching such competencies. This study aims to analyze and compare mental models of two distinct procedures in plastic surgery, breast augmentation and flexor tendon repair, to develop a framework to define cognitive competencies in plastic surgery aided by a review of the literature.

METHODS

Based on data from a-priori cognitive task analyses, literary sources, and field observations of breast augmentation surgery and flexor tendon repair, task-lists were produced for each procedure. Two mental models were developed using fuzzy logic cognitive maps to visually illustrate and analyze cognitive processes employed in either procedure. A comparison of the models aided by literature was used to define the cognitive competencies employed, identify differences in the decision-making process, and provide a guiding framework for understanding cognitive competencies.

RESULTS

Five distinct cognitive competency domains were identified from the literature applicable to plastic surgery, namely situation awareness, decision-making, task management, leadership, and communication and teamwork. Differences in processes of decision-making employed between an elective and a trauma setting were identified. A framework to map cognitive competencies within a generic mental model in surgical care was synthesized and methods were suggested for training on such competencies.

CONCLUSION

Cognitive competencies in different settings in plastic surgery are introduced using a comparative study of two mental models of distinct procedures to guide the teaching and assessment of such competencies.

Comparison Of Endoscopic Transaxillary And Peri-areolar Approaches In Breast Augmentation With Smooth Implants

INTRODUCTION

The most common surgical approaches for breast augmentation in Asia have traditionally been peri-areolar and transaxillary. In recent years, transaxillary approach has become increasingly popular with the use of endoscopic methods, which result in safer and better outcomes. In the literature, there are no comparison studies of endoscopic transaxillary and peri-areolar approaches.

METHODS

This prospective study compared the outcomes of 275 women undergoing primary breast augmentation (endoscopic transaxillary n=205, peri-areolar n=70). All procedures were performed by a single surgeon using smooth round silicone implants and dual-plane pockets from April 2013 to March 2016. Every patient was monitored for a minimum of 4 years for minor and major complications.

RESULTS

Types and percentage of patients experiencing minor complications among transaxillary and peri-areolar patients were localized fluid collection in the wound (1% transaxillary, 7.1% peri-areolar), hypertrophic scarring or keloids (1% transaxillary, 8.6% peri-areolar), and areolar and nipple deformity (0% transaxillary, 8.6% peri-areolar). Major complications were postoperative bleeding (0% transaxillary, 2.9% peri-areolar) and capsular contracture, Baker Group III or IV (1% transaxillary, 5.7% peri-areolar).

CONCLUSIONS

Endoscopic transaxillary breast augmentation had better outcomes, with lower rates of complications than the peri-areolar approach. Reviewing the literature, our study is the first direct comparison of peri-areolar and endoscopic transaxillary incisions using smooth implants. With the risk of anaplastic large cell lymphoma associated with certain macrotexture implants, endoscopic transaxillary approach using smooth implants is the safer technique and very good alternative choice for Asian women who do not want any scarring on their breasts.

Factors Affecting Lower-pole Stretch after Breast Augmentation

Breast augmentation surgical planning based on soft-tissue characteristics including the type of lower-pole pocket direction has been described. Objective outcome measures of the effects of some of these choices on postoperative lower-pole settling, including dual-plane dissection type, have been lacking.

Epidemiologic Characteristics and Postoperative Complications following Augmentation Mammaplasty: Comparison of Transgender and Cisgender Females

Breast augmentation in transgender women can be an important first step in addressing gender incongruence and improving psychosocial functioning. The aim of this study was to compare postoperative outcomes of augmentation mammoplasty in transgender and cisgender females.

Lateral Inframammary Approach for Asian Augmentation Mammaplasty

Background:

The inframammary fold (IMF) approach for augmentation mammaplasty is less popular in Asia. The incision was modified to lateral IMF(L-IMF) for easy access and better outcome. The aim of this study was to evaluate if L-IMF approach is feasible in Asian women.

Methods:

Between 2002 and 2016, 53 patients with 96 augmentation mammaplasties were performed using lateral (L-IMF, 31 cases, 56 breasts) and traditional IMF approaches (T-IMF, 22 cases, 40 breasts). Surgical outcome was compared between L-IMF and T-IMF groups. Scar was assessed using photographic images by 4 assessors with a modified Manchester Scar Score, and telephone surveys available in L-IMF group.

Results:

The average age was 41 ± 10.7 years (range, 20–73 years). There were no statistical differences in demographics in both groups besides of implant type (P < 0.01). At a follow-up of 80.1 months (range, 20–173 months), the capsular contracture rate and overall complication rate were statistically lower in L-IMF group, 3.6%, and 3.6%, than in T-IMF group, 15%, and 20% (P = 0.05, and P < 0.01, respectively). The modified Manchester Scar for L-IMF scars was 8.47 ± 2.4. The average score of 24 of 31 patients with L-IMF incision was 3.8 ± 0.96/5 points with patient-reported questionnaire. Nineteen patients (79.2%) would recommend or strongly recommend the procedure to friends.

Conclusions:

The scar of L-IMF group healed satisfactorily with lower capsular contracture and overall complication rates than T-IMF group. Patients were satisfied with the outcome of breast augmentation and scar appearance using L-IMF approach.

Capsular Contracture Rate After Breast Augmentation with Periareolar Versus Other Two (Inframammary and Transaxillary) Incisions: A Meta-Analysis

BACKGROUND

Capsular contracture has been the most common complication of cosmetic breast augmentation. The effect of incision pattern on capsular contracture is still unclear. This meta-analysis demonstrates current evidence with regard to the comparison of capsular contracture rate between periareolar and other two (transaxillary and inframammary) incisions.

METHODS

PubMed, EMBASE, and Cochrane databases were searched up to January 2017. The results of selected studies were meta-analyzed to obtain a pooled odds ratio of the effect of periareolar versus other two incision patterns (transaxillary or inframammary incision) of breast augmentation on capsular contracture rates. In addition, subgroup analyses were performed on periareolar versus transaxillary groups and periareolar versus inframammary groups with regard to capsular contracture rate.

RESULTS

Seven comparative studies were selected and meta-analyzed. Five of the seven studies reported a higher rate of capsular contracture on patients with periareolar incisions. The results showed a significantly higher rate of capsular contracture with periareolar incisions compared with other two incisions (OR, 1.83; 95% CI, 1.06-3.15, p = 0.03). Subgroup results showed no significant difference of capsular contracture between periareolar incisions and transaxillary incisions (OR, 0.94; 95% CI, 0.52-1.64, p = 0.79) and showed a significantly higher rate of capsular contracture in periareolar incisions compared to inframammary incisions (OR, 1.91; 95% CI, 1.06-3.43, p = 0.03).

CONCLUSION

The results of this meta-analysis demonstrate the contributing effects of periareolar breast augmentation on the rate of capsular contracture. However, more studies with longer tracking periods and higher quality should be conducted to further verify this conclusion.

What Are the Principles That Guide Behaviors in the Operating Room?: Creating a Framework to Define and Measure Performance

OBJECTIVE

To identify the core principles that guide expert intraoperative behaviors and to use these principles to develop a universal framework that defines intraoperative performance.

BACKGROUND

Surgical outcomes are associated with intraoperative cognitive skills. Yet, our understanding of factors that control intraoperative judgment and decision-making are limited. As a result, current methods for training and measuring performance are somewhat subjective-more task rather than procedure-oriented-and usually not standardized. They thus provide minimal insight into complex cognitive processes that are fundamental to patient safety.

METHODS

Cognitive task analyses for 6 diverse surgical procedures were performed using semistructured interviews and field observations to describe the thoughts, behaviors, and actions that characterize and guide expert performance. Verbal data were transcribed, supplemented with content from published literature, coded, thematically analyzed using grounded-theory by 4 independent reviewers, and synthesized into a list of items.

RESULTS

A conceptual framework was developed based on 42 semistructured interviews lasting 45 to 120 minutes, 5 expert panels and 51 field observations involving 35 experts, and 135 sources from the literature. Five domains of intraoperative performance were identified: psychomotor skills, declarative knowledge, advanced cognitive skills, interpersonal skills, and personal resourcefulness. Within the advanced cognitive skills domain, 21 themes were perceived to guide the behaviors of surgeons: 18 for surgical planning and error prevention, and 3 for error/injury recognition, rescue, and recovery. The application of these thought patterns was highly case-specific and variable amongst subspecialties, environments, and individuals.

CONCLUSIONS

This study provides a comprehensive definition of intraoperative expertise, with greater insight into the complex cognitive processes that seem to underlie optimal performance. This framework provides trainees and other nonexperts with the necessary information to use in deliberate practice and the creation of effective thought habits that characterize expert performance. It may help to identify gaps in performance, and to isolate root causes of surgical errors with the ultimate goal of improving patient safety.

Open Capsulotomy: An Effective but Overlooked Treatment for Capsular Contracture after Breast Augmentation

Background:

The prevailing theory for capsular contracture after breast augmentation is a subclinical capsular infection. A capsulectomy, site change, and implant replacement are recommended. An open capsulotomy leaves the capsule in the patient. Theoretically, such a procedure would be ineffective because it does not remove the infected tissue. Recurrences occurred frequently in women treated in the 1970s when leaky silicone gel implants were in use. Open capsulotomy has not been studied in women implanted with third-generation devices.

Methods:

Seventy-five consecutive women with Baker III/IV capsular contractures after breast augmentation treated with open capsulotomies between 1996 and 2016 were retrospectively evaluated. The original implants were usually saline-filled (72.2%). Replacements were all smooth and round, and 92.6% were also saline-filled.

Results:

Seventeen women (22.7%) developed a recurrent capsular contracture. Two patients (2.7%) experienced a second recurrence. Patients with ruptured silicone gel implants (n = 13) had a significantly greater risk of recurrence (P = 0.01). There was no significant difference in recurrence rates comparing patients whose intact implants were reinserted (12.5%) with women whose intact implants were replaced (18.2%). Povidone–iodine irrigation did not affect the recurrence rate. Capsular contracture was corrected with 1 procedure in 77.3% of patients and 2 procedures in 97.3% of patients.

Conclusions:

Open capsulotomy is a safe and effective treatment that avoids the additional morbidity and cost of a capsulectomy. The findings challenge the infected biofilm theory of capsular contracture. Open capsulotomy deserves reconsideration by plastic surgeons.

Scar Assessment After Breast Augmentation Surgery with Axillary Incision versus Inframammary Fold Incision: Long-Term Follow-Up in Chinese Patients

BACKGROUND

The inframammary fold (IMF) incision is widely used in Western countries for breast augmentation surgery, whereas the axillary incision is the dominant approach used in China, because many Chinese surgeons believe that the Asian population has a higher risk of developing hypertrophic scars. However, comparative data of scar assessment through different incisions in Chinese patients are scarce. The aims of the study were as follows: (1) to evaluate the outcomes of scar assessment using the Vancouver scar scale (VSS), combined with patient satisfaction scoring, in the scar assessment after breast augmentation surgery; (2) to compare the long-term cosmetic effects of surgical scars between axillary and IMF incisions.

METHODS

Consecutive patients coming to our department for follow-up care at least 1 year after primary breast augmentation surgeries with axillary and IMF incisions between January 1, 2014 and December 31, 2014 were included in the research. Internal consistency, inter-rater reliability, and convergent validity were examined for the VSS and patient satisfaction scoring. The baseline characteristics and scar scores were tested using the Mann-Whitney U-test and Student's t test between the two groups.

RESULTS

Sixty-one patients underwent implantation surgeries through the axillary incisions, and 17 patients through the IMF incisions. There were no significant differences in age, follow-up time, body mass index, implant volume, or implant projection between groups. Reliability and validity of the VSS and patient satisfaction scoring were satisfactory. The scores of pigmentation were higher in the IMF group than those in the axilla group with statistical significance (P < 0.05). The scores of other subscales, overall VSS scores, and patient satisfaction were not statistically significant. The scars were significantly longer in the axilla group compared with the IMF group (P < 0.05).

CONCLUSIONS

The VSS combined with patient satisfaction scoring constitutes an effective tool to evaluate incision scars after augmentation mammaplasty. Scars in the axilla and IMF can achieve comparable cosmetic effects and patient satisfaction in Chinese women. Chinese patients with proper indications can receive breast augmentation surgery through the IMF incision, with fewer risks and less trauma, and get satisfactory scar appearance as through the axillary incision.

Chinese women's preferences and concerns regarding incision location for breast augmentation surgery: a survey of 216 patients

BACKGROUND

The axillary approach is the dominant incision used in China for breast augmentation. Systematic preoperative education regarding incision locations for breast augmentation is scarce in China. In this study, we surveyed Chinese patients to ascertain their preferences and concerns for incision location based on a comprehensive understanding of different incisions.

METHODS

We used a literature review, patient interviews, and expert panels to develop the preoperative education material and questionnaire regarding different incision locations. The respondents were requested to choose one incision location before and after they received the preoperative education. Their initial choices and final decisions as well as the reasons for these choices were recorded and analyzed. Multinomial logistic regression was preformed to analyze the affecting factors on the incision choice.

RESULTS

A total of 216 Chinese women participated in the study between 2012.5 and 2014.1. Initially, 176 (81.48%) women chose axillary incision, 27 (12.50%) chose periareolar incision, and 13 (6.02%) chose inframammary fold (IMF) incision. After they received preoperative education on incisions, the axillary and periareolar approaches decreased to 117 (54.17%) and 13 (6.02%), respectively, while IMF increased to 86 (39.81%). The easily hidden scar (43.98%), lower capsular contracture rate (23.15%), and lower possibility of injury to the breast parenchyma (17.13%) ranked as the top 3 reasons for the incision choice. Patients with a preoperative cup size of AA were 12.316 times more likely to choose the axillary approach relative to the IMF approach compared with those with a B cup (P = 0.044; 95% confidence interval [CI] 1.069-141.923). For each one-unit increase in BMI, the odds that a patient would choose the axillary versus the periareolar approach decreased by 32.4% (P = 0.049; 95% CI 0.457-0.999).

CONCLUSIONS

The systematic and objective preoperative education material and questionnaire regarding different incision locations helped the Chinese patients make truly informed decisions and express their personal requirements. The axillary approach was the first option for more than half of Chinese women mainly because an easily hidden scar was considered the primary concern during the decision-making process. The patients with a low BMI and a small preoperative breast cup size were more likely to choose an axillary incision. However, a considerable number of Chinese women would choose the IMF incision and value its superiority in terms of a lower capsular contracture rate, less tissue trauma, and lower possibility of injury to the breast parenchyma.

Prevention of implant malposition in inframammary augmentation mammaplasty

Background

Implant malposition can produce unsatisfactory aesthetic results after breast augmentation. The goal of this article is to identify aspects of the preoperative surgical planning and intraoperative flap fixation that can prevent implant malposition.

Methods

This study examined 36 patients who underwent primary dual plane breast augmentation through an inframammary incision between September 1, 2012 and January 31, 2013. Before the surgery, preoperative evaluation and design using the Randquist formula were performed. Each patient was evaluated retrospectively for nipple position relative to the breast implant and breast contour, using standardized preoperative and postoperative photographs. The average follow-up period was 10 months.

Results

Seven of 72 breasts were identified as having implant malposition. These malpositions were divided into two groups. In relation to the new breast mound, six breasts had an inferiorly positioned and one breast had a superiorly positioned nipple-areolar complex. Two of these seven breasts were accompanied with an unsatisfactory breast contour.

Conclusions

We identified two main causes of implant malposition after inframammary augmentation mammaplasty. One cause was an incorrect preoperatively designed nipple to inframammary fold (N-IMF) distance. The breast skin and parenchyma quality, such as an extremely tight envelope, should be considered. If an extremely tight envelope is found, the preoperatively designed new N-IMF distance should be increased. The other main cause of malposition is failure of the fascial suture from Scarpa's fascia to the perichondrium through an inframammary incision. As well, when this fixation is performed, it should be performed directly downward to the perichondrium, rather than slanted in a cranial or caudal direction.

Axillary endoscopic subglandular tunneling approach for types 2 and 3 dual-plane breast augmentation

BACKGROUND

Dual-plane techniques offer excellent pocket locations for breast augmentation. Traditional techniques require incisions in the inframammary or periareolar crease, which are rarely accepted in the authors' department because of visible scars on the breast. Therefore, the authors developed a transaxillary approach for dual-plane procedures using an endoscope.

METHODS

During a period of 36 months between April 2009 and March 2012, 89 consecutive patients with small breasts were treated surgically. They underwent transaxillary types 2 or 3 dual-plane breast augmentation as outpatients. For the axillary endoscopic subglandular tunneling approach (AESTA), a long subglandular tunnel was created along the lateral portion of the pectoralis major muscle to reach the nipple-areolar complex. The type 2 dual-plane technique was applied in 67 patients, and the type 3 technique was used in 22 patients.

RESULTS

The mean age of the patients was 37.5 years (range 31-48 years), and the mean postoperative follow-up period was 11 months (range 7-42 months). Good surgical outcomes were obtained, and the procedure was reproducible.

CONCLUSIONS

The use of AESTA allowed the authors to achieve types 2 and 3 dual-plane breast augmentation through a transaxillary incision. They believe that AESTA can yield constant and satisfactory outcomes similar to the inframammary and periareolar approaches.

Comparison of breast augmentation incisions and common complications

BACKGROUND

Incisions for insertion of breast implants are most commonly placed in the inframammary fold, areola, or axilla. Previous studies have evaluated selection of incision location preoperatively and for nipple-areola complex sensation retention after primary augmentation mammaplasty. This study compares the most common postoperative complications for each incision location in patients who underwent primary breast augmentation.

METHODS

A retrospective chart review was performed on 619 patients who underwent primary breast augmentation, excluding simultaneous mastopexy, within a single group practice from July 1994 to June 2009. Incision location, postoperative complications (capsular contracture, hematoma formation, rippling, infection, and rupture), and total reoperation rates were recorded. Incision locations were also compared with respect to implant fill type (saline or silicone gel) and pocket location (subglandular or submuscular).

RESULTS

A statistically significant association was identified between total reoperation and incision location (p = 0.0054). The highest rate of total reoperation occurred when using an inframammary fold incision compared to either the transaxillary or periareolar. This relationship with total reoperation was not attributed to the five complications analyzed, but rather with patient desire for size/style change, asymmetry, or ptosis. No statistically significant association was observed between incision location and specific complications such as capsular contracture, rippling, implant rupture, hematoma, or infection.

CONCLUSIONS

None of the five complications analyzed correlated with incision location. The data generated from this study will assure the surgeon that all three incision locations are safe. Preoperative examination, patient preference, and surgeon comfort should remain the mainstays of incision planning in augmentation mammaplasty.

Breast augmentation: Part III--preoperative considerations and planning

The past four decades since the introduction of silicone mammary prostheses have seen significant improvements in their quality and durability. Advances in our understanding of the aetiopathology and prevention of adverse capsular contracture (ACC) have occurred such that surgical technique itself has now probably become the single most important determinant of both immediate and long-term outcome. Considered a simple, and in some quarters mindless, procedure it has evolved such that high-quality short- and stable long-term results are now expected. Whilst the fundamentals of breast augmentation (BA) remain, evolutionary philosophies confront today's surgeon with a wealth of options. Of fundamental importance has been the paradigm shift from a purely, or predominantly, volumetric, through biodimensional to a tissue-based approach. With BA, more than any other aesthetic procedure, possessing more variables, choice and influential external factors a thorough understanding of the myriad options available is essential. This review seeks to cover the key elements in obtaining an optimal primary result. It provides a rational basis for the selection of an option tailored to both the patient and the individual tissue characteristics in addition to the pertinent medico-legal issues.

A 15-year experience with primary breast augmentation

BACKGROUND

This study evaluated patients who underwent primary breast surgery within a single group practice from 1994 to 2009. Reoperations were divided by reoperation reason into total reoperations and implant-specific reoperations. The authors hypothesized that the implant-specific reoperation rate will provide the most accurate measurement of complications caused by the breast implant device.

METHODS

A total of 812 patients received the same brand of breast implant for primary breast augmentation or augmentation/mastopexy. Safety and efficacy data were recorded and complication rates were calculated. Statistics were applied using Kaplan-Meier estimated cumulative incidence calculations.

RESULTS

This study included 482 patients with saline and 330 patients with silicone implants. The most common complications included capsular contracture, rippling, rupture, infection, and hematoma. A total of 8.2 percent of patients developed Baker grade III/IV capsular contracture by 6 years. The raw incidence of rippling was 7.1 percent, and the rate was significantly increased in underweight patients with subglandular saline implants (p = 0.045). The rate of total reoperation at 1 year was 14.2 percent. While a significantly increased rate of total reoperation was seen for silicone compared with saline implants (p < 0.01), no difference was seen in the rate of implant-specific reoperation for saline compared to silicone implants (p = 0.582).

CONCLUSIONS

The use of total reoperation rates as an indication of complications of breast implants can lead to both an overestimation of implant-related complications and the inaccurate conclusion that silicone implants result in higher complication rates than saline implants. The implant-specific reoperation rate may provide a more accurate incidence of implant complications than the total reoperation rate, which includes reoperations for factors unrelated to the implant.

Aesthetic breast augmentation and thoracic deformities

To ensure the best results from aesthetic breast augmentation, preoperative evaluation and adequate patient information are essential. However, assessment of the underlying thoracic shape often is neglected. Patients with obvious deformities are aware of the problematic reconstruction, whereas patients with mild or moderate deformities often are not aware of their condition and fail to see that standard breast augmentation will lead to unsatisfying results. The authors reviewed their charts for patients with breast augmentation and mild to moderate thoracic deformities, then compiled the therapeutic possibilities and the outcome. Of the 548 patients who underwent breast augmentation, 7.1% (n = 39) exhibited low- or midgrade thoracic wall deformities. Almost none of the patients were aware of their deformity. The patients were augmented with silicone-filled, textured round implants. Placement and volume were adapted to the anatomic situation. A reoperation was not performed in any case, and both patient and physician satisfaction was high. The percentage of patients with thoracic deformity in this group was high compared with an overall incidence of less than 2%. This emphasizes the need for cautious physical examination and preoperative documentation. By individualized surgical planning and diligent implant selection, optimal results and patient satisfaction can be achieved.
