Breast augmentation: choosing the optimal incision, implant, and pocket plane

A retrospective study of 220 patients was performed to review surgical design in breast augmentation. Three specific issues were studied: incision site, implant variables, and pocket plane selection. The influence of these three factors on aesthetic results in both primary and secondary cases was the focus of the analysis. No attempt was made to address long-term issues such as capsular contracture or saline implant deflation rates. In 77 primary augmentation patients and 80 unilateral augmentations for symmetry in breast reconstruction, there were the following untoward results: 11 revisions for unilateral malposition, change to a different implant shape, or change to a larger implant size; four deflations of saline implants requiring replacement; and four conversions of saline to silicone gel implants. In 63 secondary cases, there were two hematomas and two infections requiring implant removal and subsequent replacement. Operative technique in breast augmentation is described, as are recommendations for each of the options associated with the three variables studied.     

Breast reconstruction using an inflatable breast implant with detachable reservoir

An inflatable breast implant having a detachable filling reservoir is described. Once in position, the implant can be filled under controlled conditions postoperatively. The implant functions either as a tissue expander or as a delayed-filling implant in the initial stages of the procedure. Once the desired breast size is achieved, the reservoir is removed, leaving the filled implant in position. This implant has been used successfully in various types of breast reconstructive procedures, including both primary and secondary reconstruction following modified mastectomy, immediate reconstruction following subcutaneous mastectomy, secondary reconstruction following radical mastectomy combined with the latissimus dorsi flap, and following the removal of silicone gel implants with associated capsular contracture. A total of 23 patients, representing 34 breasts, are reported on. The results have been encouraging over a period of 20 months of follow-up.     

Aesthetic reconstruction of the tuberous breast deformity

The tuberous breast deformity is a rare entity affecting young women bilaterally or unilaterally. The deformity is characterized by a constricting ring at the base of the breast, which leads to deficient horizontal and vertical development of the breast with or without herniation of the breast parenchyma toward the nipple-areola complex and areola enlargement. Several methods have been put forward to correct the deformity, but most of these fail to address the issue of the constricting ring and subsequently yield results that are not aesthetically satisfactory. A new approach to the treatment of the deformity is presented, which consists of a periareolar approach and rearrangement of the inferior part of the breast parenchyma by division of the constricting ring, thus creating two breast pillars. These pillars are allowed to redrape, and in cases of volume deficiency, a silicone breast implant is placed in a subglandular pocket. The procedure is completed by a donut-type excision to address the size of the nipple-areola complex. The technique has used on 11 patients (21 breasts) with excellent aesthetic results.     

Characteristics of a population of women with breast implants compared with women seeking other types of plastic surgery

Several previous studies have shown that breast implant patients demonstrate a number of differences compared with the general population. However, studies have not compared patients with breast implants with women receiving other types of plastic surgery, of interest because this latter group has been proposed as a comparison group for assessing the long-term health effects experienced by breast implant patients. Questionnaire data obtained from 7447 breast implant patients and 2203 patients with other types plastic surgery were collected during the course of a retrospective cohort study, to determine whether implant patients demonstrate different characteristics compared with a more restricted group of patients. In contrast to previous investigations that compared implant patients with the general population, distinctive differences with respect to family income, number of pregnancies, alcohol consumption, cigarette smoking, or histories of previous gynecologic operations or operations for benign breast disease were not found. However, implant patients were significantly more likely than other plastic surgery patients to be white, have low levels of education, have early ages at first birth, be thin, and be screened frequently for breast disease. Furthermore, implant patients reported somewhat greater use of exogenous hormones and familial histories of rheumatoid arthritis. These results support the notion that other plastic surgery patients are a more appropriate comparison group than women in the general population for studies of the health effects of breast implants; however, there continue to be distinctive characteristics possessed by breast implant patients, which need to be taken into account in an assessment of what disease effects can be uniquely attributed to silicone breast implants.     

Immediate breast reconstruction using a laparoscopically harvested omental flap

Use of an omental flap to reconstruct the breast after cancer surgery was first reported by Kiricuta in 1963. Since then, the omentum has been widely used in cancer surgery to cover extensive thoracic defects associated with radionecrosis. In contrast, for breast reconstruction or augmentation mammaplasty, rectus abdominis and latissimus dorsi flaps have been used far more often than omental flaps. This article describes a new technique for immediate breast reconstruction using laparoscopically harvested omentum and reports the results obtained in 10 patients. Nine patients underwent immediate breast reconstruction after subcutaneous mastectomy. In the other patient, omentum was used in combination with skin grafting to cover a postmastectomy defect. Follow-up exceeded 16 months in the first patients. The results suggest that breast reconstruction using a laparoscopically harvested omental flap may be extremely dependable in terms of vascular supply (there was one case of partial necrosis, which healed with local management alone). The postoperative course of all patients was uneventful, and the use of laparoscopy reduced the hospital stay to less than 7 days. Donor-site scars were minimal. There was no residual loss of function, and there were no cases of incisional ventral hernia. Cosmetic results were satisfactory, with a soft breast that was both natural in appearance and stable in volume. However, in two patients the amount of omentum was found to be inadequate during the procedure; consequently, an implant was inserted under the omental flap. Breast reconstruction using a laparoscopically harvested omental flap is a new technique that allows autogenous reconstruction without disfigurement of the do-nor site and that results in a soft, natural-looking breast.     

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.     

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.     

Breast cancer stage at diagnosis and survival among patients with prior breast implants

Longstanding concern exists regarding the potential for women with breast implants to experience delayed detection of breast cancer. Furthermore, survival among cosmetic breast implant patients who subsequently develop breast cancer is a concern. Since 1976, this institution has monitored cancer incidence in a cohort of 3182 women who underwent cosmetic breast augmentation between 1959 and 1981. The distributions of stage at diagnosis and survival of the 37 women who subsequently developed in situ or invasive breast cancer were compared with the observed population distributions. The distribution of stage at diagnosis for cosmetic breast implant patients who subsequently developed breast cancer was virtually identical to that of all breast cancer patients in Los Angeles County who were of the same age and race, and were diagnosed during the same time period. Furthermore, the 5-year survival rate of the 37 patients did not differ from that which would be expected based on rates established by the U.S. National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program. These results suggest that cosmetic breast implant patients are not at increased risk of delayed detection of breast cancer, nor do they suffer a poorer prognosis when breast cancer does occur. Although the number of breast cancer patients in this study is small, the results are highly consistent with the existing epidemiologic evidence related to breast cancer detection and survival among breast implant patients. Although breast implant patients should continue appropriate breast cancer screening behavior, there seems to be no cause for alarm.     

Staged breast reconstruction with saline-filled implants in the irradiated breast: recent trends and therapeutic implications

A retrospective review was performed of one surgeon's experience with 40 consecutive patients who had undergone two-stage saline-filled implant breast reconstruction and radiation during the period from 1990 through 1997. A randomly selected group of 40 other two-stage saline-filled implant breast reconstructions from the same surgeon and time period served as controls. This review was undertaken because of the absence of specific information on the outcome of staged saline implant reconstructions in the radiated breast. Previously published reports on silicone gel implants and radiation have been contradictory. At the same time, the criteria for the use of radiation in the treatment of breast cancer have been expanded and the numbers of reconstruction patients who have been radiated are increasing dramatically. For example, in a 1985 report on immediate breast reconstruction, only 1 of 185 patients over a 6-year period underwent adjuvant radiation therapy, whereas in this review, there were 40 radiated breasts with saline-filled implants, 19 of which received adjuvant radiation therapy during their expansion. The study parameters included patient age, breast cup size, implant size, length of follow-up, number of procedures, coincident flap operations, Baker classification, complications, opposite breast procedures, pathologic stage, indications for and details about the radiation, and outcomes. The use of radiation in this review of reconstructed breasts can logically be divided into four groups: previous lumpectomy and radiation (n = 7), mastectomy and radiation before reconstruction (n = 9), mastectomy and adjuvant radiation during reconstruction/expansion (n = 19), and radiation after reconstruction (n = 5). The largest and most rapidly growing group of patients is of those receiving postmastectomy adjuvant radiation therapy. A total of 47.5 percent (19 of 40) of radiated breasts with saline implants ultimately needed the addition of, or replacement by, a flap. Ten percent of a control group with nonradiated saline implant reconstructions also had flaps, none as replacements. Fifty percent or more of both the radiated and control groups had contralateral surgery. Complications were far more common in the radiated group; for example, there were 32.5 percent capsular contractures compared with none in the control group. The control nonradiated implant-only group and the flap plus implant radiated group did well cosmetically. The radiated implant-only group was judged the worst. The increasing use of radiation after mastectomy has important implications for breast reconstruction. The possibility for radiation should be thoroughly investigated and anticipated preoperatively before immediate breast reconstruction. Patients with invasive disease, particularly with large tumors or palpable axillary lymph nodes, are especially likely to be encouraged to undergo postmastectomy radiation therapy. The indications for adjuvant radiation therapy have included four or more positive axillary lymph nodes, tumors 4 cm (or more) in diameter, and tumors at or near the margin of resection. More recently, some centers are recommending adjuvant radiation therapy for patients with as few as one positive lymph node or even in situ carcinoma close to the resection margin. The use of latissimus dorsi flaps after radiation has proven to be an excellent solution to postradiation tissue contracture, which can occur during breast expander reconstruction. The use of the latissimus flap electively with skin-sparing mastectomy preradiation is probably unwise, unless postmastectomy radiation is unlikely. Skin-sparing mastectomy with a latissimus flap thus should be preserved for patients unlikely to undergo adjuvant radiation therapy. Purely autologous reconstruction such as a TRAM flap is another option for these patients, either before or after radiation therapy.     

Long-term results of MISTI gold breast implants: a retrospective study

MISTI Gold breast implants (Bioplasty, St. Paul, Minn.) filled with polyvinylpyrrolidone-hydrogel were developed as a promising alternative to silicone-filled implants. Some studies have reported on the positive effects of the implant, such as improved radiolucency and biocompatibility of the gel; however, there are also reports that such implants increased in volume and were subject to capsular contracture in the human body, resulting in demands for their removal. The purpose of this retrospective study was to analyze the long-term results of a series of patients with MISTI Gold breast implants. Between 1991 and 1993, the authors inserted 83 MISTI Gold implants in 61 patients with an average age of 46 years (range, 16 to 69). The authors were able to follow up 48 patients with 71 MISTI Gold implants. The average follow-up was 68 months (range, 10 to 108 months). The retrospective study found that 59 percent of all MISTI Gold implants were removed after an average period of 4.14 years. The main reason for implant removal was an increase in volume of 38 percent, followed by capsular contracture in 14 percent of all 71 MISTI Gold implants. The average increase in volume of all removed MISTI Gold implants was 43 percent. Capsular contracture was graded as Baker I and II in 63 percent and as Baker III and IV in 37 percent. In conclusion, the authors believe that MISTI Gold implants do not fulfill the criteria of safe breast implants, and they agree with the December of 2000 opinion of the Medical Devices Agency of the Department of Health in London that the hydrogel-filled breast implants should not be used until more information about the filler material and its metabolic fate is available.     

Breast reconstruction using tissue expanders and implants in Hodgkin's patients with prior mantle irradiation.

Women treated for Hodgkin's disease with mantle irradiation have an increased risk for developing breast cancer. Typically, breast malignancy in Hodgkin's patients presents bilaterally in a younger age group. Skin flap ischemia, poor skin expansion, implant extrusion, capsular contracture, and poor cosmesis are common sequelae of tissue expander/implant breast reconstruction after breast irradiation for failed breast conservation therapy. This has led most surgeons to favor autologous tissue reconstruction in this setting. This study was performed to determine the efficacy of tissue expander/implant breast reconstruction in breast cancer patients who have been treated with prior mantle irradiation for Hodgkin's disease. A retrospective analysis of all breast cancer patients with a history of Hodgkin's disease and mantle irradiation treated with mastectomy and tissue expander/implant reconstruction between 1992 and 1999 was performed. There were seven patients, with a mean age of 35 years (range, 28 to 42 years). The average interval between mantle irradiation and breast cancer diagnosis was 16 years (range, 12 to 23 years). All patients underwent two-stage reconstruction. Textured surface tissue expanders were placed in a complete submuscular position at the time of mastectomy. Expansion was initiated 2 weeks after insertion and continued on a weekly basis until completion. Expanders were replaced with textured surface saline-filled implants as a second stage. Patients were evaluated for skin flap ischemia, infection, quality of skin expansion, implant extrusion, capsular contracture, rippling, symmetry, and final aesthetic outcome. Breast cancer was bilateral in five patients and unilateral in two. Two patients did not undergo simultaneous bilateral breast reconstruction because of metachronous cancer development. One of the patients had an initial transverse rectus abdominis muscle flap breast reconstruction, followed by a tissue expander/implant reconstruction of the opposite breast. The average follow-up was 3 years. Complications were limited to one case of cellulitis after implant placement that resolved with intravenous antibiotics. There were no cases of skin flap ischemia, poor skin expansion, or implant extrusion. Overall patient satisfaction was high and revisions were not requested or required. Symmetry was best achieved with bilateral implants. This study demonstrates the efficacy of tissue expander/implant breast reconstruction in patients treated with prior mantle irradiation. In this series, tissue expansion was reliable with low morbidity. Second-stage placement of permanent implants yielded good aesthetic results without significant capsular contracture. Mantle irradiation did not appear to compromise the prosthetic breast reconstruction. Tissue expander/implant breast reconstruction should remain a viable option in this category of irradiated patients.     

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.     

Clinical applications of three-dimensional photography in breast surgery

Three-dimensional imaging in breast surgery has several uses clinically. The most practical applications are for the evaluation of breast asymmetries, both congenital and acquired, and for the evaluation of factors affecting breast shape in augmentation mammaplasty. Other uses of three-dimensional imaging that we have found clinically helpful are for evaluation of patients desiring reduction mammaplasty and for evaluation of patients undergoing unilateral breast reconstruction to determine the expander and permanent implant size that gives the best symmetry with the contralateral breast. We present five cases in which we investigate the use of three-dimensional imaging clinically by using the images to determine quantitative information about the breast, such as volume or projection. Overall, three-dimensional imaging is very helpful in providing objective information about the breast for use in preoperative planning. In addition, by analyzing clinical cases, it can provide objective data about the breast and surgical mammaplasty (especially augmentation mammaplasty) that may help surgeons better understand those factors that contribute to breast shape and influence surgical outcomes. There are currently some limitations of this system, influenced by patients with significant ptosis or obesity, which may introduce errors into the three-dimensional data, making them unreliable. However, we believe three-dimensional imaging has great clinical potential in surgical mammaplasty.     

Breast reconstruction without an implant: results and complications using an extended latissimus dorsi flap

The results of 55 breast reconstructions using an extended latissimus dorsi myocutaneous flap without an implant are reported. A method for preoperatively estimating the flap volume, operative details, and a technique for insetting the flap are reviewed. Good, fair, and poor results were achieved in 69, 24, and 7 percent of patients, respectively. Examples are illustrated. The poor results were all due to major complications and are analyzed in detail. Significant complications affecting the end result occurred in 14.5 percent of patients, and nonsignificant and minor complications occurred in 33 percent. Flap volume is shown to be fairly accurately predictable. Seventy percent of flaps had a volume in excess of 400 cc. The reconstructed volume, cosmetic results, and complication rates are compared with those of other reported series. Good results can be achieved with this method, quite comparable to other methods, and with similar complication rates, but without the problems associated with the use of a prosthetic implant.     

Breast augmentation with bilateral deepithelialized TRAM flaps: an alternative approach to breast augmentation with autologous tissue

Since the 1980s, many patients have benefited from the use of the transverse rectus abdominis musculocutaneous (TRAM) flap for postmastectomy reconstruction. In addition to cancer reconstruction, this technique has recently been used to treat patients with breast implant intolerance and for reconstruction after siliconoma resection. However, physicians and patients alike believe that such an extensive procedure should not be used for aesthetic purposes, and to the authors' knowledge, no study has been reported on the use of pedicled TRAM flaps for aesthetic augmentation mammaplasty. In the past several years, a number of the authors' patients have requested simultaneous breast augmentation and abdominoplasty. These patients objected to the use of prosthetic implants because of potential complications such as implant failure, capsular contracture, wrinkling, and palpability. Therefore, from 1995 to 2000, the authors performed 14 cases of bilateral breast augmentation with deepithelialized, pedicled TRAM flaps. In this series, the donor-site complication rate was similar to that of the traditional TRAM flap. Surprisingly, no cases of complete or partial flap loss were clinically detected. The only complaints were pedicle bulges at the costal margins. These patients were all extremely satisfied with the results. It was concluded that the TRAM flap is safe for augmentation in a subset of carefully selected women with hypoplastic or atrophic breasts. The authors discuss patient selection, technique, and their experience with this method of breast augmentation.     

A holistic numerical model to predict strain hardening and damage of UHMWPE under multiple total knee replacement kinematics and experimental validation

Experimental wear testing is an essential step in the evaluation of total knee replacement (TKR) design. Unfortunately, experiments can be prohibitively expensive and time consuming, which has made computational wear simulation a more desirable alternative for screening designs. While previous attempts have demonstrated positive results, few models have fully incorporated the affect of strain hardening (or cross shear), or tested the model under more than one loading condition. The objective of this study was to develop and evaluate the performance of a new holistic TKR damage model, capable of predicting damage caused by wear, including the effects of strain hardening and creep. For the first time, a frictional work-based damage model was compared against multiple sets of experimental TKR wear testing data using different input kinematics. The wear model was tuned using experimental measurements and was then able to accurately predict the volumetric polyethylene wear volume during experiments with different kinematic inputs. The size and shape of the damage patch on the surface of the polyethylene inserts were also accurately predicted under multiple input kinematics. The ability of this model to predict implant damage under multiple loading profiles by accounting for strain hardening makes it ideal for screening new implant designs, since implant kinematics are largely a function of the shape of the components.     

The coincidence of TRAM flaps and prostheses in the setting of breast reconstruction

It is well known that transverse rectus abdominis myocutaneous (TRAM) flaps can be used to replace unsatisfactory prosthetic breast reconstructions; however, little has been written about the scope of breast implant use in TRAM flap patients. In this study, to ascertain the range of such therapeutic options, their frequency, and their clinical outcomes, the authors retrospectively reviewed the senior author's breast reconstruction experience from 1989 to 2000 with patients in whom both a TRAM flap and an implant were used for breast reconstruction. The authors examined the surgical indications, body habitus, bra size, chest wall irradiation history, flap type, implant type, complications, and outcomes for those patients with TRAM flap and breast implant combinations.Thirty-two women who had 50 (various) combinations of a TRAM flap and a breast implant were identified. There were more clinical scenarios than patients because many of the women had multiple scenarios. The 50 combination scenarios were then divided into six groups. Group I consisted of 14 patients who had elective prostheses placed beneath simultaneous TRAM flaps; group II consisted of 10 patients who had TRAM flaps with contralateral prosthetic reconstruction (in which two implants were received before the TRAM flaps, five implants were received simultaneously with the TRAM flaps, and three implants were received after the TRAM flaps); group III consisted of eight patients who had contralateral augmentation in addition to their TRAM flaps; group IV consisted of 11 patients who had TRAM flaps that were used to cover or replace previous prosthetic reconstructions; group V consisted of four patients in whom prostheses were used to augment or improve previous TRAM flap reconstructions; and group VI consisted of three patients who required prostheses to either reconstruct or salvage total or near-total TRAM flap failures. A broad range of implant types was used, although anatomic saline implants predominated. Forty-one percent of the patients in the review had undergone irradiation during the course of their treatment for breast cancer. Eight of the 32 patients experienced a total of twelve complications, four of which were related to the implants and eight of which involved the TRAM flaps and abdominal donor sites.Although complex, the wide variety of potential TRAM flap/breast implant combinations can be useful for patients with challenging reconstructive scenarios, particularly those that involve radiation therapy. In the group of patients reviewed by the authors, TRAM flaps were most often used in successful partnership either on the same side as or opposite to an implant reconstruction. A TRAM flap was used to salvage or replace an unsatisfactory implant reconstruction in less than a third of the patients. From a risk point of view, implants used opposite a TRAM flap reconstruction had a lower incidence of complication than did implants used beneath TRAM flaps.     

A system for breast implant selection based on patient tissue characteristics and implant-soft tissue dynamics

Primary breast augmentation patients have widely varying characteristics of their breast envelope, parenchyma, and adjacent tissues. When preoperative breast implant selection does not specifically address critical soft-tissue parameters individual to each patient, risks of complications increase. Complications that occur from failure to reconcile a patient's wishes for breast size with her individual tissue characteristics include skin stretch and thinning, ptosis, atrophy of parenchyma, implant edge or shell visibility, implant edge or shell palpability, visible traction rippling, "bottoming" deformities, and lateral implant displacement with widening of the intermammary distance. Previous dimensional systems address implant parenchyma base width relative to implant base width, but no published system adequately addresses or attempts to quantitate the third dimension, tissue stretch, that is critical to estimate amount of fill necessary in a wide range of breast and tissue types. This system addresses the tissue characteristics (T) of the envelope (E), the parenchyma (P), and the implant (I), and the dynamics (D) of implant and filler distribution that affect soft tissues. The acronym TEPID summarizes the key factors that determine aesthetic results and occurrence of problems and reoperations following breast augmentation. This simple, efficient, and clinically practical system focuses on only three tissue measurements to estimate implant volume required to fill each patient's existing breast envelope, on the basis of her individual tissue characteristics: base width of the parenchyma, anterior pull skin stretch, and areola- and/or nipple-to-inframammary-fold distance measured under maximal stretch. The surgeon then adjusts initial volume to address differences in degree of skin stretch (anterior pull skin stretch) and contribution of the patient's existing parenchyma to stretched envelope fill, and to address differences in implant dimensions and filler distribution dynamics. To base decisions of implant pocket location on quantifiable soft-tissue coverage thickness, the system measures soft-tissue pinch thickness of the upper pole and at the inframammary fold. Surgeon time required to measure, estimate, and make preoperative implant selection decisions is less than 5 minutes. This system evolved from compiling and reviewing measurements and results from 330 primary breast augmentations from 1996 to 1999, including round and anatomic implant types with smooth shells and two different textured shells. The TEPID system was then used concurrently with the previous dimensional system for patient tissue evaluation and preoperative implant selection in 627 consecutive primary augmentation cases over a 3-year period from January of 1998 to January of 2001. Implant selection that did not comply with the parameters of the system was necessary in only eight cases. The TEPID system is a simple, efficient, and clinically practical method that allows surgeons to base implant selection on clinically quantifiable, individual patient tissue characteristics.     

Autologous breast reconstruction with the extended latissimus dorsi flap

The extended latissimus dorsi myocutaneous flap can provide autogenous tissue replacement of breast volume without an implant. Nevertheless, experience with the extended latissimus dorsi flap for breast reconstruction is relatively limited. In this study, the authors evaluated their experience with the extended latissimus dorsi flap for breast reconstruction to better understand its indications, limitations, complications, and clinical outcomes. All patients who underwent breast reconstruction with extended latissimus dorsi flaps at the authors' institution between January of 1990 and December of 2000 were reviewed. During the study period, 75 extended latissimus dorsi flap breast reconstructions were performed in 67 patients. Bilateral breast reconstructions were performed in eight patients, and 59 patients underwent unilateral breast reconstruction. There were 45 immediate and 30 delayed reconstructions. Mean patient age was 51.5 years. Mean body mass index was 31.8 kg/m2. Flap complications developed in 21 of 75 flaps (28.0 percent), and donor-site complications developed in 29 of 75 donor sites (38.7 percent). Mastectomy skin flap necrosis (17.3 percent) and donor-site seroma (25.3 percent) were found to be the most common complications. There were no flap losses. Patients aged 65 years or older had higher odds of developing flap complications compared with those 45 years or younger (p = 0.03). Patients with size D reconstructed breasts had significantly higher odds of flap complications compared with those with size A or B reconstructed breasts (p = 0.05). Obesity (body mass index greater than or equal to 30 kg/m2) was associated with a 2.15-fold increase in the odds of developing donor-site complications compared with patients with a body mass index less than 30 kg/m2 (p = 0.01). No other studied factors had a significant relationship with flap or donor-site complications. In most patients, the extended latissimus dorsi flap alone, without an implant, can provide good to excellent autologous reconstruction of small to medium sized breasts. In selected patients, larger breasts may be reconstructed with the extended latissimus dorsi flap alone. This flap's main disadvantage is donor-site morbidity with prolonged drainage and risk of seroma. Patients who are obese are at higher risk of developing these donor-site complications. In conclusion, the extended latissimus dorsi flap is a reliable method for total autologous breast reconstruction in most patients and should be considered more often as a primary choice for breast reconstruction.     

Breast capsulorrhaphy revisited: a simple technique for complex problems

Implant malposition without capsular contracture is a common problem that has received little attention. Malposition of the implant in the inferior, lateral, or medial direction can be corrected predictably and relatively simply with capsulorrhaphy and mirror-image selective capsulotomy. In addition, capsulorrhaphy can be used to create a smaller pocket to preserve anterior projection and prevent lateral and inferior displacement when changing to a smaller implant. Eleven patients underwent capsulorrhaphy for either implant malposition or implant size reduction. Improved appearance and symmetry of the breast was accomplished in all patients without increased complications.
