The correction of capsular contracture by conversion to "dual-plane" positioning: technique and outcomes

Little has been published regarding the treatment of patients with long-established capsular contracture after previous submuscular or subglandular breast augmentation. This study reviews 7 years of experience in treating established capsular contracture after augmentation mammaplasty by relocating implants to the "dual-plane" or partly subpectoral position. A retrospective chart review was performed on all patients who were treated for capsular contracture using this technique between 1993 and 1999. Data collected included the date of the original augmentation, the original implant location, date of revision and type of implant used, length of follow-up, outcome, and any ensuing complications. Different surgical techniques were used, depending on whether the prior implant was located in a subglandular or submuscular plane. All patients had revisions such that their implants were relocated to a dual plane, with the superior two thirds or so of the implant located beneath the pectoralis major muscle and the inferior one third located subglandularly. Of 85 patients reviewed, 54 had their original implants in a submuscular position and 31 had their initial augmentation in a subglandular position. Of the 54 patients whose implants were initially submuscular, 23 patients (43 percent) had silicone gel implants, 15 patients (28 percent) had double-lumen implants, and the remaining 16 patients (30 percent) had saline implants. Of the 31 patients whose implants were initially subglandular, 20 patients (65 percent) had silicone gel implants, three patients (10 percent) had double-lumen implants, and the remaining eight patients (26 percent) had saline implants. Fifty-one patients (60 percent) had replacement with saline implants (37 smooth saline, 14 textured saline), whereas 34 (40 percent) had silicone gel implants (seven smooth gel, 27 textured gel). The average time from previous augmentation to revision was 9 years 9 months. The average follow-up time after conversion to the dual-plane position was 11.5 months. Only three of 85 patients required reoperation for complications, all of which involved some degree of implant malposition. Of patients converted to the dual plane, 98 percent were free of capsular contracture and were Baker class I at follow-up, whereas 2 percent were judged as Baker class II. There were no Baker level III or IV contractures at follow-up. The dual-plane method of breast augmentation has proved to be an effective technique for correcting established capsular contracture after previous augmentation mammaplasty. This technique appears to be effective when performed with either silicone or saline-filled implants.     

Transaxillary subpectoral augmentation in the ptotic breast: augmentation by disruption of the extended pectoral fascia and parenchymal sweep

A new approach to transaxillary subpectoral breast augmentation based on an understanding of the anatomy of the extended pectoral fascia and the inframammary fold allows for the widespread application of this technique. Previous authors have stated that transaxillary augmentation is only applicable to a small subset of the general population and is contraindicated in mild degrees of ptosis or in large augmentations. The new approach, augmentation by disruption of the extended pectoral fascia technique and the parenchymal sweep maneuver, prevents high-riding implants and double folds. By disrupting the fascia, the lower portion of the implant is able to sit in a partially subglandular rather than subfascial plane. The anatomy and clinical implications of the extended pectoral fascia are discussed, as is the augmentation by disruption of the extended pectoral fascia technique. The parenchymal sweep maneuver is also described. Clinical cases are presented.     

Mammographic measurements before and after augmentation mammaplasty

Thirty-five augmented women underwent mammography using both the standard implant-compression technique and, when possible, the implant-displacement technique; all had preaugmentation film-screen mammography available for evaluation. The area of mammographically visualized breast tissue before and after augmentation mammaplasty was measured using a transparent grid. Patients with subglandular implants had a mean decrease of 49 percent of measurable tissue area with compression mammography and a 39 percent decrease with displacement mammography. Patients with submuscular implants had a 28 percent decrease in measurable tissue area with compression mammography and a 9 percent decrease with displacement mammography. Anterior breast tissue was seen better with displacement mammography; posterior breast tissue, with compression mammography. Most patients had some degree of parenchymal scarring and lower image quality after augmentation. State-of-the-art mammography was not possible in most patients augmented with silicone-gel-filled implants.     

Subfascial breast implant: a new procedure

Breast augmentation techniques using the submuscular and subglandular planes to introduce the implant are well known and widely used procedures. The authors have been using the subfascial dissection plane, a new concept for breast augmentation. From October of 1998 to September of 2001, 263 patients underwent breast augmentation. In all cases, the implants were inserted into the subfascial plane. McGhan 410 anatomic biodimensional, cohesive gel implants (size, 155 to 310 g) were used. There are additional benefits using this technique; these include avoiding implant deformation or distortion (as seen in the retromuscular position), leaving additional soft tissue between the implant and the skin, and minimizing implant edge prominence (inherent to retroglandular placement). These technical details lead to fewer patient complaints. Morbidity is similar to that of other techniques.     

Augmentation mammaplasty by cadaver fat allografts

Two Soviet women were treated for complications of breast hardening and tenderness following augmentation mammaplasty using cadaver fat allografts. The cadaver fat grafts were excised and replaced with silicone-gel prostheses in the submammary pockets. The implants were found to contain necrotic fat tissue with areas of fibrosis and calcification; however, no signs of rejection were evident. Both patients had a successful postoperative outcome.     

Breast cancer after augmentation mammaplasty: treatment by skin-sparing mastectomy and immediate reconstruction

Breast conservation has been associated with poor cosmetic outcome when used to treat breast cancer in patients who have undergone prior augmentation mammaplasty. Radiation therapy of the augmented breast can increase breast fibrosis and capsular contraction. Skin-sparing mastectomy and immediate reconstruction are examined as an alternative treatment.Six patients with prior breast augmentation were treated for breast cancer by skin-sparing mastectomy and immediate reconstruction. One patient underwent a contralateral prophylactic skin-sparing mastectomy. Silicone gel implants had been placed in the submuscular location in five patients and in the subglandular position in one patient a mean of 10.2 years (range, 6 to 20 years) before breast cancer diagnosis. The mean patient age was 41.3 years (range, 33 to 56 years). Four independent judges reviewed postoperative photographs to grade the aesthetic results in comparison with the opposite native or reconstructed breast.The American Joint Committee on Cancer staging was stage 0 in one patient, stage I for four patients, and stage II for one patient. Five of the six patients presented with a palpable breast mass. Latissimus dorsi flap reconstruction was performed in four patients (bilaterally in one) and a transverse rectus abdominis muscle (TRAM) flap was used in two patients. Three patients were treated by skin-sparing mastectomy with preservation of the breast implant (two patients with latissimus flaps, and one patient with a TRAM flap). The tumor location necessitated the removal of implants in two patients (one patient with a latissimus flap and one with a TRAM. A saline implant was placed under the latissimus flap after gel implant removal. The patient who underwent bilateral skin-sparing mastectomies desired explantation and placement of saline implants. No remedial surgery was performed on the opposite breast to achieve symmetry. Complications occurred in two patients at the latissimus dorsi donor site (seroma in one patient, and seroma and infection in one). Five patients underwent complete nipple reconstructions. The mean duration of follow-up was 33.6 months (range, 15.5 to 70.3 months), and there were no recurrences of breast cancer. The aesthetic results were judged to be good to excellent in all cases.Skin-sparing mastectomy and immediate reconstruction can be used in patients with prior breast augmentation, with good to excellent cosmetic results. Depending on the tumor and implant location, the implant may be preserved without compromising local control.     

Prospective analysis of the outcome of subpectoral breast augmentation: sensory changes, muscle function, and body image

This study is a prospective analysis of the outcome of subpectoral breast augmentation. Forty-seven patients undergoing breast augmentation were studied. They were assessed for pectoralis muscle function, breast sensation, and body image before and after subpectoral breast augmentation with saline implants. The patients were evaluated as follows: Pectoralis function was determined by measuring maximal voluntary isometric force. Sensation was evaluated by two means: vibration and pressure. The patient's body image was assessed using the Multidimensional Body-Self Relations Questionnaire. Results indicated a significant change in breast sensation at 3 months postoperatively but not at 6 months. Pectoralis muscle function did not significantly change during the study period. Body image was significantly improved at both postoperative measuring periods. The authors conclude that breast augmentation results in improved body image with negligible effect on muscle or nerve function.     

Foreign-body reaction to silicone gel in axillary lymph nodes after an augmentation mammaplasty.

A radical mastectomy was performed for a breast adenocarcinoma occurring 10 years after a subpectoral augmentation mammaplasty with silicone gel-filled prostheses. A foreign-body reaction to silicone was seen in two of the axillary lymph nodes resected.     

Introduction of breast implants through the abdominal route.

We present our technique of doing an abdominal lipectomy and augmentation mammaplasty in the same operation, through the same incision, in selected patients. We introduce the breast implants through tunnels made from the top of the abdominal pocket into the breast areas. We have had no complications in 12 patients in whom we have done this operation.     

Transumbilical endoscopic breast augmentation: submammary and subpectoral

Endoscopic techniques have recently been applied to aesthetic cosmetic surgery procedures. Endoscopic bilateral augmentation mammaplasty through a transumbilical approach ("TUBA") has recently been advocated as an alternative technique. The purpose of this article is to describe the author's transumbilical technique, to identify procedural limitations and special considerations, and to retrospectively analyze preliminary results. Five hundred thirteen patients (n = 1026 breasts) who underwent submammary transumbilical augmentation from January of 1993 through December of 1998 were evaluated. In 1997, the technique was further developed to permit subpectoral placement of implants; an additional 140 patients (n = 280 breasts) who underwent subpectoral transumbilical augmentation from September of 1997 through February of 1999 will also be presented. Success of the technique was based upon a number of criteria, including completion of the operation without conversion to an inframammary incision or reoperation, normal nipple-areola sensation, absence of hematoma formation, absence of infection, no umbilical scar revision, and patient satisfaction. Complications included hematoma (n = 2 breasts), conversion to inframammary incision (n = 5 breasts), and required secondary corrective procedure (n = 3 breasts). The majority of these complications occurred early in the learning curve. The successful augmentation rate in 1306 breasts was 99.2 percent. Based upon these results, transumbilical endoscopic breast augmentation is believed to be a safe alternative technique with excellent results.     

Autogenous augmentation mammaplasty with microsurgical tissue transfer

Many patients dream of reducing their abdominal or gluteal fat tissue and, in the same procedure, enlarging their breasts without the need for implants and their related problems. Following this demand, a new "natural" alternative to breast augmentation with autogenous tissue is presented. Since 1993, 16 patients have undergone either unilateral or bilateral breast augmentation with free fat transfer. These 20 augmentation mammaplasties consisted of nine deep inferior epigastric perforator flaps, eight superior gluteal artery perforator flaps, and three superficial inferior epigastric artery flaps. The postoperative results were judged aesthetically by independent examiners and by the patients according to Netscher's score. The additional operations for final shaping of the breasts and the postoperative complications at the donor and recipient sites are reported. The augmented breasts improved the aesthetic proportions more than 100 percent. All flaps survived, and except for minor postoperative complications such as small areas of wound dehiscence, the breasts could be shaped aesthetically in a second-stage procedure several weeks later. Breast augmentation with autogenous tissue offers a natural alternative to alloplastic augmentation mammaplasty.     

Long-term use of polyurethane breast prostheses: a 14-year experience

I have used polyurethane prostheses for the past 14 years, implanting 220 implants into 130 patients who desired breast reconstruction after subcutaneous mastectomy or cancer ablation or simply breast augmentation. I theorize that a polyurethane-covered implant resists contracture, retaining its compressibility because the fibroblasts proliferate into the polyurethane in many different directions. When the fibrils contract, the forces of contracture counterbalance one another, resisting contracture. However, when smooth prostheses are implanted, fibrils are directed in a circular fashion around the implant and naturally contract, leading to firmer breasts. There were 115 prostheses inserted following subcutaneous mastectomy, and 22 percent developed contracted capsules. Seven implants became exposed because of skin necroses; one was removed because of a Staphylococcus infection; and two patients developed a combination of polyurethane and silicone granulomas. These developed only with the earlier implant, where there was shedding of the polyurethane sponge layer and silicone bled from the low-viscosity silicone used in the earlier implants. No granulomas were noted with the currently used Surgitek Replicon implant. Eighty-five breasts were reconstructed after cancer ablation with polyurethane implants, and the contracture rate was 2.3 percent. Other complications were minimal. A smaller group of patients had augmentation mammaplasty, and 20 prostheses were placed in 10 patients. A 15 percent contracture rate was noted in this group. In this study, 82 percent of patients were followed for up to 14 years. Capsular contractures occurred in 30 implants between 1 and 11 years, for an average recurrence at 6.3 years. The overall contracture rate was 13 percent. Other complications were minimal. All implants were placed subcutaneously or subglandularly, and all were drained.     

Postmastectomy reconstruction of the previously augmented breast: diagnosis, staging, methodology, and outcome

Although many of the health and safety issues associated with breast augmentation have been thoroughly discussed over the past decade, the literature is remarkably silent regarding postmastectomy reconstruction of the previously augmented breast. A retrospective review of the senior author's reconstructive practice was performed for the years 1983 through March of 1999, revealing 21 women who underwent postmastectomy breast reconstruction after previous breast augmentation. For purposes of measuring aesthetic results, these 21 patients were matched to a carefully selected control group of 15 patients. They were also compared with other, larger populations, including 777 of the senior author's other breast reconstructions, the breast cancer registry at the Lombardi Cancer Center in Washington, D.C., and several large, published epidemiologic studies.The interval between the previous augmentation and the diagnosis of breast cancer ranged from 9 months to 18 years, with a mean of 9.3 years. None of the previous augmentation implants was ruptured at the time of mastectomy. Of the nine patients with previous subpectoral augmentation, cancer was detected mammographically in five (56 percent), whereas of the 12 patients with previous subglandular augmentation, cancer was first detected mammographically in only three (25 percent). This difference was not statistically significant (p = 0.2). Overall, eight of the study patients' tumors (38 percent) were first detected mammographically, which is similar to other published reports of breast cancer patients in the general population. Seventy-one percent of the 21 study patients were node-negative, which also compares favorably with other published series.Sixteen of the women with previous augmentation (76 percent) had purely prosthetic reconstructions. Flaps were used in the other five reconstructions (23 percent): three latissimus dorsi flaps (14 percent) and two transverse rectus abdominis musculocutaneous flaps (9 percent). All five flaps were used in patients who had undergone radiation therapy. Throughout the senior author's entire reconstructive practice history, transverse rectus abdominis musculocutaneous flaps were more frequently used [282 of 777 nonaugmented reconstructions (36 percent)], whereas latissimus dorsi flaps were less frequently used [17 of 777 nonaugmented reconstructions (2.2 percent)] (p < 0.001).The cosmetic results of the breast reconstructions in the previously augmented study group were generally good-to-excellent, with a mean score by blinded observers of 3.35 of a possible 4.0. These results were comparable to or better than those in the matched controls, who scored a mean of 3.0.     

Recurrence of subglandular breast implant capsular contracture: anterior versus total capsulectomy

The objective of this study was to determine whether the type of capsulectomy, anterior or total, affects the recurrence of capsular contracture around subglandular silicone-gel breast implants. A retrospective analysis was performed of patients who underwent either anterior or total capsulectomy for Baker grade 3 or 4 subglandular capsular contracture in our unit. All patients were invited to a review clinic where their capsular status was assessed. There were 100 anterior- disc capsulectomies in 60 patients between 1988 and 1997 and 99 total capsulectomies in 60 patients between 1990 and 1998. The follow-up in the former group was a median of 7 years and mean 6.9 years, compared with median 2.5 and mean 3.1 years in the latter group. Eighty-six percent of the implants removed from both groups at capsulectomy were smooth-walled gel-filled implants. Sixty-nine breasts in the anterior group received textured gel implants at capsulectomy; the remaining 31 received polyurethane-coated Meme implants. In the total capsulectomy group, all but two breasts (one patient) received textured gel implants. After review, the capsular status was known in 80 percent of the anterior and 92 percent of the total capsulectomy group. The review clinic found eight new contractures in five patients to have developed in the anterior compared with none in the total group. Recurrent contractures affected 50 percent of patients (46 percent of breasts) in the anterior and 11 percent of patients (10 percent of breasts) in the total capsulectomy group. Kaplan-Meier survival analysis was applied to the data. By including only patients who received textured gel implants at capsulectomy, the Logrank found a statistical difference between the two treatment groups (0.01 < p < 0.5). We believe that this study provides some evidence that total capsulectomy for subglandular silicone breast implant capsular contracture results in a lower capsular recurrence than anterior- disc capsulectomy. The pattern and risk of recurrence after total capsulectomy and exchange for a modern textured prosthesis appear to approach those following primary augmentation.     

Comparison of the Postoperative Incidence Rate of Capsular Contracture among Different Breast Implants: A Cumulative Meta-Analysis

BackgroundA large number of clinical studies have reported that the different materials used in breast implants were a possible cause of the different incidence rates of capsular contracture observed in patients after implantation. However, this theory lacks comprehensive support from evidence-based medicine, and considerable controversy remains.ObjectivesIn this study, a cumulative systematic review examined breast augmentation that used implants with textured or smooth surfaces to analyze the effects of these two types of implants on the occurrence of postoperative capsular contracture.MethodsWe conducted a comprehensive search of literature databases, including PubMed and EMBASE, for clinical reports on the incidence of capsular contracture after the implantation of breast prostheses. We performed a cumulative meta-analysis on the incidence of capsular contracture in order from small to large sample sizes and conducted subgroup analyses according to the prosthetic material used, the implant pocket placement, the incision type and the duration of follow-up. Relative risks (RR) and 95% confidence intervals (CI) were used as the final pooled statistics.ResultsThis meta-analysis included 16 randomized controlled trials (RCTs) and two retrospective studies. The cumulative comparison of textured and smooth breast implants showed statistical significance at 2.13 (95% CI, 1.18-3.86) when the fourth study was entered into the analysis. With the inclusion of more reports, the final results indicated that smooth breast implants were more likely to be associated with capsular contracture, with statistical significance at 3.10 (95% CI, 2.23-4.33). In the subgroup analyses, the subgroups based on implant materials included the silicone implant group and the saline implant group, with significant pooled statistical levels of 4.05 (95% CI, 1.97-8.31) and 3.12 (95% CI, 2.19-4.42), respectively. According to implant pocket placement, a subglandular group and a submuscular group were included in the analyses, and only the subglandular group had a statistically significant pooled result of 3.59 (95% CI, 2.43-5.30). Four subgroups were included in the analyses according to incision type: the inframammary incision group, the periareolar incision group, the transaxillary incision group and the mastectomy incision group. Among these groups, only the pooled results of the inframammary and mastectomy incision groups were statistically significant, at 2.82 (95% CI, 1.30-6.11) and 2.30 (95% CI, 1.17-4.50), respectively. Three follow-up duration subgroups were included in the analyses: the one-year group, the two- to three-year group and the ≥five-year group. These subgroups had statistically significant results of 4.67 (95% CI, 2.35-9.28), 3.42 (95% CI, 2.26-5.16) and 2.71 (95% CI, 1.64-4.49), respectively.ConclusionIn mammaplasty, the use of textured implants reduces the incidence of postoperative capsular contracture. Differences in implant pocket placement and incision type are also likely to affect the incidence of capsular contracture; however, this conclusion awaits further study.     

Incidence and Risk Factors of Striae Distensae Following Breast Augmentation Surgery: A Cohort Study

Background

The significant increase in the popularity of breast augmentation surgeries has led to an increase in the number and types of complications; among these is the postoperative occurrence of Striae Distensae (SD). The objective of this study was to investigate the incidence of SD and describing its occurrence in association with age, breast implant volume, history of SD, history of pregnancies and breastfeeding, body mass index (BMI), changes in postoperative weight, smoking habits, and use of oral contraceptives.

Methods

A cohort study was conducted and the patient data from a specific social group that underwent augmentation mammaplasty with silicone breast implants in a private clinic was analyzed.

Results

563 patients entered the cohort, while 538 completed the study. The SD incidence was 7.06%. The risk was almost the double at 22–28 years of age and triple in women of 21 years of age or less. The women who did not use oral contraceptives were 2.59 times more likely of developing SD. A higher incidence of SD was observed among those with normal or low BMI values, smokers, and in those who had implants larger than 300 ml.

Conclusions

Young age, larger implant volumes, smoking, and normal or low BMI values were the risk factors responsible for the development of SD; while using oral contraceptives was found to be a protective factor.     

Capsular contracture after breast reconstruction with silicone-gel and saline-filled implants: a 6-year follow-up

A major problem after breast reconstruction with augmentation mammaplasty is contracture of the fibrous capsule around the prosthesis. In a series of 72 breasts in 65 women, silicone-gel and saline-filled implants were randomly selected prior to breast reconstruction. The results were judged with respect to consistency, tenderness, wrinkles, and sounds by two independent plastic surgeons according to the breast augmentation classification (BAC) and by the patients themselves. Capsular contracture was found by the surgeons in 50 percent of the gel implant group and in 16 percent of the saline implant group, which is in conformity with the results of the follow-up 5 years earlier. The incidence of deflation was 16 percent in the saline group and occurred in different sizes of both overinflated and underinflated prostheses. The degree of slow leakage from saline implants will be discussed. Despite the high rate of contractures in the gel group, 85 percent of all patients were satisfied with the result of the reconstruction.     

Achieving a predictable 24-hour return to normal activities after breast augmentation: Part II. Patient preparation, refined surgical techniques, and instrumentation.

The goal of this study was to develop practices that would allow patients undergoing subpectoral augmentation to predictably return to full normal activities within 24 hours after the operation, free of postoperative adjuncts. Part I of this study used motion and time study principles to reduce operative times, medication dosages, perioperative morbidity, and recovery times in augmentation mammaplasty. Part II of the study focuses on details of patient education, preoperative planning, instrumentation, and surgical technique modifications that were identified, modified, and implemented to achieve the results reported in part I.Two groups of 16 patients each (groups 1 and 2) were studied retrospectively for comparison to a third group of 627 patients (group 3) studied prospectively. Patients in group 1 had axillary partial retropectoral breast augmentations in 1982-1983, using dissociative anesthesia, blunt instrument implant pocket dissection, and Dow Corning, double-lumen implants containing 20 mg of methylprednisolone and 20 cc of saline in the outer lumen of the implants. Patients in group 2 (1990) had inframammary, retromammary augmentations by using a combination of blunt and electrocautery dissection, Surgitek Replicon polyurethane-covered, silicone gel-filled implants, and general endotracheal anesthesia. Patients in group 3 (1998 to 2001, n = 627) had inframammary partial retropectoral, inframammary retromammary, and axillary partial retropectoral augmentations under general endotracheal anesthesia. Refined practices and surgical techniques from studies of groups 1 and 2 were applied in group 3.Videotapes from operative procedures of groups 1 and 2 were analyzed with macromotion and micromotion study principles, and tables of events were formulated for each move during the operation for all personnel in the operating room. Extensive details of surgical technique were examined and reexamined in 13 different stages by using principles of motion and time studies described in part I of this study to maximize efficiency without any change in quality. Unnecessary or unproductive motions and techniques were progressively eliminated, and essential, productive techniques were streamlined to eliminate wasted time and motion. Instrumentation and surgical techniques were evaluated in detail and modified to minimize bleeding and tissue trauma.Detailed data were presented in part I of this study that document shorter operative times, recovery times, time to discharge home, and time to return to normal activities. This part focuses on the patient education, preoperative planning, instrumentation, and surgical technique changes that were implemented on the basis of the findings in part I of the study. More extensive patient information integrated with staged informed consent resulted in a more informed and confident patient. Applying motion and time study principles to analysis and refinement of instrumentation and surgical techniques resulted in a substantial reduction in perioperative morbidity and a simpler, shorter 24-hour return to full normal activity for 96 percent of the patients undergoing breast augmentation in group 3 compared with groups 1 and 2. More than 96 percent of patients in group 3 were able to return to normal activities, lift their arms above their heads, lift normal-weight objects, and drive their car within 24 hours after their partial retropectoral breast augmentation.Patient education, preoperative planning, instrumentation, and surgical technique modifications based on motion and time study video analyses reduced surgical trauma and bleeding, reduced perioperative morbidity, and allowed 96 percent of 627 breast augmentation patients in group 3 a predictable return to full, normal activity in 24 hours or less. Specific surgical factors that contributed to these results included (1) prospective hemostasis techniques with a zero tolerance for even the smallest amount of bleeding, (2) strict "no-touch" techniques for periosteum and perichondrium, (3) eliminating all blunt dissection, (4) performing all dissection under direct vision, (5) modified and simplified instrumentation, and (6) optimal use of muscle relaxants during subpectoral dissection.     

Capsule injection for the prevention of contracture

From 1990 through 1999, 164 patients with prior augmentation mammaplasty underwent implant removal by the author, and 128 of the patients had the implants replaced. Of that group, 86 were noted on preoperative examination to have capsule contracture of grade III or IV. Patients with preoperative capsule contracture were offered the option of a postoperative injection of triamcinolone intended to prevent recurrent contracture. Patients who elected to have replacement with gel-filled implants were excluded. A total of 48 patients underwent injection of triamcinolone 4 to 6 weeks after surgery. Of the remaining 38 patients, 12 were not offered injection because they selected gel-filled implants and 26 declined injection. Follow-up ranged from 8 months to 10 years (mean, 46 months), and no patient was followed up for less than 8 months. Of the 48 patients who received injections, two developed recurrent contracture, one at 3 years and one at 4.5 years. Of the 26 patients who declined injection, eight had recurrent contracture (three bilateral) within 12 months. These data suggest that in this high-risk group of patients, a postoperative injection of triamcinolone can reduce the risk of recurrent contracture.     

Anterior thoracic hypoplasia: a separate entity from Poland syndrome

SUMMARY: Women presenting with anterior thoracic depression, breast hypoplasia, and subsequent asymmetry are often diagnosed with Poland syndrome regardless of pectoralis involvement, or are placed in the generic category of breast asymmetry or skeletal dysplasias. Recently, though, the term "sunken chest" has been used to describe forms of chest wall depression that previously may have fallen under generic skeletal dysplasias. The authors believe that, combined with hypoplasia of the ipsilateral breast, superior location of the nipple-areola complex compared with the contralateral side, and normal pectoralis muscles, this represents a previously undefined and real condition called anterior thoracic hypoplasia. During the past 4 years, the authors have treated eight women who have presented with a diagnosis of Poland syndrome or pectus excavatum, all of whom share the same characteristics-unilateral sunken anterior chest wall, hypoplasia of the breast, superiorly placed nipple-areola complex, normal pectoralis muscle, and normal sternal position. All of the patients underwent correction of breast asymmetry and unilateral anterior thoracic hypoplasia with augmentation mammaplasty, a method that when tailored for each side yields good aesthetic results. The average age of the patients was 31 years and the average chest size was 34. Cup size, as measured by the patient's standard bra, was a B on the nonaffected side in all patients and an A on the affected side in all patients except one. Of the eight patients, seven had the right anterior chest and breast involved, whereas one patient had involvement on the left. For all of the patients, the nipple and areola of the hypoplastic side were smaller and in a more superior position compared with the contralateral side on visual inspection. In the eight patients, a total of 19 augmentations (15 primary augmentations and four revisions) and one mastopexy were performed. Ten inframammary-fold approaches and nine periareolar approaches were used, and all of the implants were placed in a partial submuscular position, except for two implants placed in a subglandular position that were converted to partial submuscular positions in a secondary setting. In all the women, the sternal head of the pectoralis muscle was present and the pectoralis muscle appeared to be equal in size compared to the contralateral side. Nine different types of implants were used. Average implant fill volume measured 412 cc on the hypoplastic side and 257 cc on the contralateral side. In follow-up, all of the patients were satisfied with their operation and rated their aesthetic outcome as very good to excellent. The authors believe that anterior thoracic hypoplasia is a real, previously misdiagnosed and undescribed condition, and that both chest wall and breast deformities can be corrected safely and with excellent results using proper augmentation planning and implant selection.
