RESUMEN

BACKGROUND: Smooth, round, silicone implants predominate device-based breast reconstruction in the USA; despite their prevalence, complications can include bottoming out, superior contour deformity, rippling, and/or lateral malposition. This complication profile increases the need for revision surgery and subsequent patient dissatisfaction. With the resurgence of shaped, textured, silicone implants in the USA, we report the senior author's success with these devices and outline a strategy to optimize outcomes in breast reconstruction surgery. METHODS: A retrospective chart review was conducted on a prospectively collected IRB-approved database of nipple-sparing mastectomies (NSMs) with immediate breast reconstruction with smooth, round, silicone implants (Group A) in 2011 in comparison to textured, shaped, silicone implants (Group B) in 2012. Changes in operative technique were highlighted and extrapolated. Outcomes were reviewed. RESULTS: In Group A, 128 NSMs were performed in 76 patients. In Group B, 109 NSMs were performed in 59 patients. Thirteen percent of patients in Group A had direct to implant reconstruction as compared with 21% in Group B. Patients with textured, shaped implants were more likely to have acellular dermal matrix (61 vs 34%, p < 0.0001) than those with smooth, round implants. Patients who had smooth, round implants were more likely to have postoperative nipple malposition (18 vs 0%, p < 0.0001,) and rippling (29 vs 0%, p < 0.0001.) Patients with textured, shaped implants had fewer operative revision reconstructions as compared with those with smooth, round implants (36.71 vs 12.8%, p < 0.0001) Based on these results, our technique has evolved and has eight key technical modifications. CONCLUSION: With a few adaptations in surgical technique, the transition to textured, shaped, silicone devices for breast reconstruction can be seamless with superior breast contour and reduced complications/revision rates.

RESUMEN

BACKGROUND: Lockwood described the importance of Colles' fascia anchoring in medial thighplasty to reduce morbidity associated with the procedure. However, this maneuver may still have complications including traumatic dissection, prolonged edema, and potential wound healing ramifications form increased tension. Alternatively, we suggest orienting tension in medial thighplasty for massive weight loss (MWL) patients in the horizontal vector rather than a vertical direction, negating the need for Colles' fascia anchoring. OBJECTIVES: To compare the morbidities, complications, and outcomes between Colles' fascia suture fixation (CFSF) and horizontal vector fixation (HVF) in medial thighplasties in MWL patients. METHODS: A retrospective chart review was conducted on an Institutional Review Board approved database of MWL patients who had medial thighplasty between October 2004 and March 2014. Patient demographics and surgical outcomes were reviewed between those MWL patients with CFSF and HVF. RESULTS: Of 65 post-MWL patients, 26 (40.0%) patients were in the CFSF group, and 39 (60.0%) patients were in the HVF group. The 2 groups had statistically equivocal preoperative characteristics and comorbidities. Intraoperatively, the HVF group had increased use of barbed suture (92.3% vs 30.6%, P < 0.0001) and liposuction (71.8% vs 26.9%, P < 0.0001). Postoperatively, the HVF group had decreased incidence of infection (5.1% vs 23.0%, P = 0.051) and lymphocele/seroma (10.3% vs 34.6%, P = 0.0257). No statistical differences were observed for dehiscence, necrosis, or hematoma. CONCLUSIONS: HVF for medial thighplasty in MWL patients is a safe and effective procedure, with a lower complication profile than CFSF. Furthermore, the incorporation of barbed sutures and/or liposuction may help to achieve optimal results. LEVEL OF EVIDENCE: 3.

RESUMEN

Unilateral breast reconstruction poses a special set of challenges to the reconstructive breast surgeon compared to bilateral reconstructions. No studies to date provide an objective comparison between autologous and implant based reconstructions in matching the contralateral breast. This study compares the quantitative postoperative results between unilateral implant and autologous flap reconstructions in matching the native breast in shape, size, and projection using three-dimensional (3D) imaging. Sixty-four patients who underwent unilateral mastectomy with tissue expander (TE)-implant (n = 34) or autologous microvascular free transverse rectus abdominus myocutaneous (TRAM; n = 18) or deep inferior epigastric artery perforator (DIEP; n = 12) flap (n = 30) reconstruction from 2007 to 2010 were analyzed. Key patient demographics and risk factors were collected. Using 3D scans of patients obtained during pre and postoperative visits including over 1 year follow-ups for both groups, 3D models were constructed and analyzed for total breast volume, anterior-posterior projection from the chest wall, and 3D comparison. No significant differences in mean age, body mass index, or total number of reconstructive surgeries were observed between the two groups (TE-implant: 52.2 ± 10, 23.9 ± 3.7, 3 ± 0.9; autologous: 50.7 ± 9.4, 25.4 ± 3.9, 2.9 ± 1.3; p > 0.05). The total volume difference between the reconstructed and contralateral breasts in the TE-implant group was insignificant: 27.1 ± 22.2 cc, similar to the autologous group: 29.5 ± 24.7 cc, as was the variance of breast volume from the mean. In both groups, the reconstructed breast had a larger volume. A-P projections were similar between the contralateral and the reconstructed breasts in the TE-implant group: 72.5 ± 3.21 mm versus 71.7 ± 3.5 mm (p > 0.05). The autologous reconstructed breast had statistically insignificant but less A-P projection compared to the contralateral breast (81.9 ± 16.1 mm versus 61.5 ± 9.5 mm; p > 0.05). Variance of A-P projection from the mean was additionally insignificant between the contralateral and reconstructed breasts. Both groups produced similar asymmetry scores based on global 3D comparison (TE-implant: 2.24 ± 0.3 mm; autologous: 1.96 ± 0.2 mm; p > 0.05). Lastly, when the autologous group was further subdivided into TRAM and DIEP cohorts, no significant differences in breast volume, A-P projection or symmetry existed. Using 3D imaging, we demonstrate that both TE-implant and autologous reconstruction can achieve symmetrical surgical results with the same number of operations. This study demonstrates that breast symmetry, while an important consideration in the breast reconstruction algorithm, should not be the sole consideration in a patient' decision to proceed with autologous versus TE-implant reconstruction.

RESUMEN

BACKGROUND: Abdominal wall flaps are routinely used in reconstructive procedures. In some patients inadequate venous drainage from the deep vein may cause fat necrosis or flap failure. Occasionally the superficial inferior epigastric vessels (SIEV) are of sufficient size to allow for microvascular revascularization. This study looked at the ratio of the sub- and suprascarpal fat layers, the number of deep system perforators, and SIEV diameter to determine any correlation of the fat topography and SIEV. METHODS: 50 abdominal/pelvic CT angiograms (100 hemiabdomens) were examined in women aged 34-70 years for number of perforators, SIEV diameter, and fat pad thickness above and below Scarpa's fascia. Data was analyzed using multivariate model. RESULTS: The average suprascarpal and subscarpal layers were 18.6 ± 11.5 mm and 6.2 ± 7.2 mm thick, respectively. The average SIEV diameter was 2.06 ± 0.81 mm and the average number of perforators was 2.09 ± 1.03 per hemiabdomen. Hemiabdomens with suprascarpal thickness>23 mm had greater SIEV diameter [2.69 mm vs. 1.8 mm (P < 0.0001)] The fat layer thickness did not correlate with the number of perforators. Neither subscarpal fat thickness nor suprascarpal-to-subscarpal fat layer thickness correlated significantly with SIEV caliber or number of perforators in multivariate model. CONCLUSIONS: Suprascarpal fat pad thicker than 23 mm had larger SIEVs irrespective of the number of deep system perforators. This may indicate a cohort of patients at risk of venous congestion from poor venous drainage if only the deep system is revascularized. We recommend harvesting the SIEV in patients with suprascarpal fat pad >23 mm to aid in superficial drainage.

RESUMEN

Circumferential bodylift is a powerful procedure for achieving dramatic and natural body contouring changes in the massive weight loss patient. The care of these patients has raised our awareness of several important issues including safety, nutritional status, skin quality, recurrent laxity, surgical steps, and postoperative scars. Integration of this knowledge with various technical modifications over the last 15 years has improved our care for this cohort. We have not only seen a rise in the number of surgeries performed, but also the development of principles, techniques, and details that the authors feel necessary to share to achieve improved contour and more predictable outcomes. LEVEL OF EVIDENCE 4: Therapeutic.

RESUMEN

BACKGROUND: Nipple-sparing mastectomy (NSM) through an inframammary fold (IMF) incision can provide superior cosmesis and a high level of patient satisfaction. Because of concerns for nipple-areolar complex (NAC) viability using this incision, selection criteria may be limited. Here, we evaluate the impact of scarring from prior lumpectomy on NAC viability. METHODS: A retrospective chart review was conducted on a prospectively collected database at a single institution between July 2006 and October 2012. A total of 318 NSMs through IMF incisions were performed. We compared the incidence of NAC ischemia in 122 NSM cases with prior lumpectomy with 196 NSM cases without prior lumpectomy. All 318 mastectomies were followed by implant-based reconstruction. Clinicopathologic factors analyzed included indications for surgery, technical details, patient demographics, comorbidities, and adjuvant therapy. RESULTS: The overall incidence of NAC ischemia was 20.4% (65/318). Nipple-areolar complex ischemia occurred in 24.6% (30/122) of cases with prior lumpectomy and 17.9% (35/196) of cases without prior lumpectomy (P = 0.1477). Among the 30 ischemic events in the 122 cases with prior lumpectomy, epidermolysis occurred in 20 (16.4%) and necrosis occurred in 10 (8.2%). Two cases (1.6%) required operative debridement. Seven cases (5.7%) were left with areas of residual NAC depigmentation. All other cases completely resolved with conservative management. There was no significant correlation between the incidence of ischemia and surgical indication, tumor staging, age, body mass index, tissue resection volume, sternal notch to nipple distance, prior radiation, single-stage reconstruction, sentinel or axillary lymph node dissection, acellular dermal matrix use, presence of periareolar lumpectomy scars, diabetes, or smoking history. At a mean follow-up of 505 days (range, 7-1504 days), patient satisfaction was excellent. Local recurrence of breast cancer occurred in 3 cases (2.5%), and distant recurrence occurred in 2 cases (1.6%). CONCLUSIONS: Patients with scarring from prior lumpectomy do not have a higher rate of NAC ischemia and may be considered for NSM via an IMF incision.

RESUMEN

BACKGROUND: Nipple-sparing mastectomy through an inframammary fold incision (NSM-IMF) with implant-based reconstruction (IBR) is a cosmetically preferable approach to breast cancer treatment in appropriate candidates. However, patients who have undergone prior cosmetic breast surgery (CBS) may be at increased risk for postoperative complications secondary to existing surgical scars. OBJECTIVE: To assess whether prior CBS increases the risk of complications following NSM-IMF with IBR. METHODS: A retrospective chart review was conducted for 398 NSM-IMFs with IBR performed between July 2006 and December 2013. CBS cases were identified. Outcomes were reviewed. RESULTS: Of 398 NSM-IMF cases, 41 had prior CBS: 24 augmentations, 12 reductions, three mastopexies, and two augmentation mastopexies. NSM-IMF was performed an average of 8 years following CBS. CBS cases had lower BMIs (P = .040), more breast tissue resected (P = .021), wider breast bases (P = .0002), more single-stage reconstructions (P < .0001), more ADM use (P < .0001), and larger permanent implants (P = .0051) than those without CBS. Postoperatively, CBS cases had higher rates of mastectomy flap ischemia (P = .0392) and hematoma (P = .0335). Among CBS cases, single-stage reconstruction was associated with increased full-thickness flap ischemia (P = .0066). Compared to prior augmentation cases, prior reduction/mastopexy cases had higher rates of capsular contracture (P = .0409) and seroma (P = .0226). CONCLUSIONS: This series is the largest to date to evaluate the success of NSM-IMF with IBR in CBS patients. These women should be cautiously considered for IBR, particularly in the setting of single-stage reconstruction. LEVEL OF EVIDENCE: 4 Therapeutic.

RESUMEN

Elephantiasis nostras verrucosa (ENV) is a rare cutaneous sequela of chronic lymphedema. Treatment of ENV remains poorly elucidated but has historically involved conservative management aimed at relieving the underlying lymphedema, with a few cases managed by surgical intervention. We report a case of a 27-year-old male with primary lymphedema complicated by large painful ENV lesions on his left foot that we excised surgically with good functional and cosmetic results as validated by the patient. To our knowledge, this is the first report of a case of ENV with a pedunculated morphology and the presence of a deep invasive stalk.

RESUMEN

UNLABELLED: The goal of evidence-based medicine (EBM) is for health-care professionals to incorporate existing medical evidence into clinical practice to achieve the greatest possible outcomes. The theory of EBM has been employed since the 11th century and has evolved dramatically into the modern application used by practicing physicians today. There are five levels of evidence currently used to evaluate if certain techniques, methods, and surgical procedures are the "best" to be used in practice. Despite the outlined format of EBM, plastic surgeons have difficulty applying EBM in clinical practice because of the influence of expert opinion and the subjective nature of outcomes. This article explores the function of EBM in aesthetic plastic surgery. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.

RESUMEN

PURPOSE: As Botox(®)/filler use has increased in recent years, a growing number of nonaesthetic health professionals have emerged to perform these procedures. Since studies have shown that patients identify training as the most important factor in considering these procedures, this study seeks to summarize the perspective of plastic surgeons regarding these paradigm shifts. METHODS: In the summer of 2013, an eight-question survey was sent to members of ISAPS, ASAPS, and ASPS (approximately 26,113 plastic surgeons globally). Two questions assessed practice location and membership affiliation and six questions assessed various healthcare practitioners' capability to administer Botox, fillers, and vaccines (control). Healthcare practitioners included plastic surgeons and dermatologists, gynecologists, dentists, nurses in plastic surgery and dermatology, or nurses in other fields. RESULTS: On three e-mail notifications, 14,184 plastic surgeons opened the survey and 882 responded: 36.6 % from North America, 29.1 % from Europe, 12.9 % from South America, 10.1 % from Asia, 4.5 % from the Middle East, 3.4 % from Australia, 1.9 % from Africa, and 1.6 % from Central America. Seventy-seven percent believed nurses were not as capable as plastic surgeons in administering Botox; 81 % felt the same for fillers. Conversely, 84 % agreed that nurses were as capable as plastic surgeons in administering vaccines. Plastic surgeons ranked nurses in other fields (48 %) as most capable in administering vaccines, then plastic surgeons (42 %), nurses of plastic surgeons (9 %), gynecologists (1 %), and dentists (<1 %). When asked about Botox/fillers, responders ranked plastic surgeons (98 %) most capable, then nurses in plastic surgery (2 %), gynecologists (<1 %), dentists (<1 %), and nurses in other fields (<1 %). When asked to rank according to patient perception, the order remained the same. CONCLUSION: Based on responses from over 880 plastic surgeons from around the world, plastic surgeons consider themselves and dermatologists the most capable injectors. However, they still believe nurses in other fields to be the most capable of administering vaccines. This dichotomy may define the role of various practitioners in an increasingly more competitive injectable environment to improve patient satisfaction and outcomes. Given that the majority of growth in cosmetic injectables is being driven by providers other than plastic surgeons and dermatologists, further clarification on training requirements and practice guidelines may be necessary to ensure a consistent, reproducible experience for the patient.

RESUMEN

UNLABELLED: Phyllodes tumors (PT) are rare fibroepithelial breast tumors representing less than 1 % of all breast malignancies. These tumors are unpredictable and fast growing with a high local recurrence rate, making this disease challenging to treat. Previous literature focused on surgical resection, and breast reconstruction following a mastectomy in patients with PT is rarely addressed. We report a case of a recurrent malignant PT treated with a nipple-sparing mastectomy followed by immediate single-stage silicone implant breast reconstruction. While PT is a rare breast malignancy that presents challenges with both surgical resection and reconstruction, we demonstrate that nipple-sparing mastectomy with immediate implant breast reconstruction with AlloMax is curative and can offer an appealing cosmetic option.

RESUMEN

BACKGROUND: Nipple-sparing mastectomy performed via an inframammary fold incision with implant-based reconstruction is an oncologically safe procedure that provides excellent cosmesis. OBJECTIVES: The authors report their experience with conservative treatment of postoperative nipple-areolar complex (NAC) ischemia and an analysis of risk factors for NAC ischemia and conservative treatment failure. METHODS: A retrospective chart review was conducted of 318 nipple-sparing mastectomies performed through inframammary fold incisions with implant-based reconstruction between July 2006 and October 2012. NAC dressings consisted of topical nitroglycerin, external warming for 24 hours, antibacterial petrolatum gauze, and a loose bra for 1 week. Patients were monitored for NAC ischemia as the primary endpoint. NAC ischemia was treated with bacitracin ointment. In cases of full-thickness ischemia, expanders were also partially deflated. RESULTS: Partial- and full-thickness NAC ischemia occurred in 44 (13.8%) and 21 (6.6%) cases, respectively. All partial- and 17 full-thickness cases resolved with conservative treatment. Of these, 7 partial- and 2 full-thickness cases suffered residual depigmentation. Four full-thickness cases required operative debridement. Factors associated with NAC ischemia included increasing age (P = .035), higher body mass index (P = .0009), greater breast volume (P = .0023), and diabetes (P = .0046). Factors associated with conservative treatment failure included increasing age (P < .0001), higher body mass index (P = .014), greater breast volume (P = .020), smoking (P = .0449), acellular dermal matrix use (P < .0001), and single-stage reconstruction (P = .0090). CONCLUSIONS: Postoperative NAC ischemia can be effectively managed conservatively to preserve cosmesis and implant viability. Knowledge of risk factors for NAC ischemia and conservative treatment failure may improve future patient counseling and outcomes.

RESUMEN

BACKGROUND: Loss of volume after autologous fat transfer to the breast is well documented, and various methods to improve long-term survival of fat grafts have been investigated (including both distant and neighboring harvest sites), but no optimal technique has been identified. OBJECTIVE: The authors compare fat graft survival from 2 anatomical donor sites to determine whether there is an optimal site for fat graft harvesting in breast reconstruction. METHODS: Seventy-three patients (109 breasts) who received fat grafting to reconstructed breasts from 2009 to 2012 were enrolled in this retrospective study and divided into 2 groups: group A had fat harvested from the abdomen and group B from the thighs. Fat grafting was performed using a modified Coleman technique for symmetry. For all patients, 3-dimensional scans were obtained and volumes were analyzed. RESULTS: Forty-six patients (66 breasts) received an average of 101 mL of fat injected from the abdomen, and 27 (43 breasts) received an average of 102 mL from the thighs. Group A had 82% volume retention at 16 days, 63% at 49 days, and 45% at 140 days. Group B had 86% at 16 days, 63% at 49 days, and 46% at 140 days (P > .05). Patients were also stratified by radiation exposure and volume injected; neither affected donor site volume retention (P > .05). CONCLUSIONS: Our data suggest that donor site, regardless of volume injected or tissue radiation, did not affect volume retention in fat grafting. Longer-term studies are needed to assess the stability of the breast after fat grafting.

RESUMEN

PURPOSE: The aim of this study was to demonstrate that modern data mining tools can be used as one step in reducing the labor necessary to produce and maintain systematic reviews. METHODS: We used four continuously updated, manually curated resources that summarize MEDLINE-indexed articles in entire fields using systematic review methods (PDGene, AlzGene, and SzGene for genetic determinants of Parkinson disease, Alzheimer disease, and schizophrenia, respectively; and the Tufts Cost-Effectiveness Analysis (CEA) Registry for cost-effectiveness analyses). In each data set, we trained a classification model on citations screened up until 2009. We then evaluated the ability of the model to classify citations published in 2010 as "relevant" or "irrelevant" using human screening as the gold standard. RESULTS: Classification models did not miss any of the 104, 65, and 179 eligible citations in PDGene, AlzGene, and SzGene, respectively, and missed only 1 of 79 in the CEA Registry (100% sensitivity for the first three and 99% for the fourth). The respective specificities were 90, 93, 90, and 73%. Had the semiautomated system been used in 2010, a human would have needed to read only 605/5,616 citations to update the PDGene registry (11%) and 555/7,298 (8%), 717/5,381 (13%), and 334/1,015 (33%) for the other three databases. CONCLUSION: Data mining methodologies can reduce the burden of updating systematic reviews, without missing more papers than humans.

BACKGROUND: Pseudoptosis (bottoming out) is a well-observed phenomenon occurring after all types of breast reduction surgery. The authors' team previously reported the use of three-dimensional (3D) imaging to demonstrate that significant morphologic changes occur in the breast during the first year after short-scar medial pedicle breast reduction. This study extended this evaluation to postoperative year 3. METHODS: Patients undergoing short-scar medial pedicle breast reduction had 3D photographs taken using the Canfield Vectra 3-pod system or the Konica Minolta V910 during postoperative follow-up visits at 1 month, 1 year, 2 years, and 3 years. Patients were assessed for pseudoptosis and breast morphologic changes using the 3D-based measurements. RESULTS: During the 3 year period, 10 patients completed the study. The total breast volume decreased significantly during the first postoperative year by 20.6% (P < 0.05). No change in volume occurred during postoperative years 2 and 3 (P > 0.05). Pseudoptosis was documented in the first postoperative year by a 6% migration of breast tissue from the upper pole to the lower pole of the breast (P < 0.05), without significant change noted during the next 2 postoperative years (P > 0.05). This redistribution of the breast parenchyma correlated with a decrease in breast anteroposterior projection of 10.6 mm (P < 0.05) during the same period, with an insignificant change during postoperative years 2 and 3. During the first postoperative year, 3D comparative analysis recorded a 4.4-mm difference in the 3D topography (P < 0.05) and no further changes thereafter. The angle of breast projection showed a significant decrease of 17% (P < 0.05) in the first postoperative year and no change in subsequent years. CONCLUSION: Three-dimensional photography is a useful tool enabling the plastic surgeon to monitor the postoperative changes in breast morphology objectively. This study provides quantifiable data demonstrating that pseudoptosis and tissue redistribution are limited to the initial postoperative year for patients undergoing short-scar medial pedicle breast reduction. The kinetic change in the breasts during postoperative years 2 and 3 appears to be minimal. Studies comparing the changes in morphology over time with different techniques of breast reduction are underway.

RESUMEN

BACKGROUND: There has been an increase in body contouring procedures following massive weight loss (MWL), including male breast reduction procedures. Treating male chest deformity after MWL using standard mastopexy techniques often leads to suboptimal results. OBJECTIVES: The authors describe a technique to treat pseudogynecomastia using a modified elliptical excision and nipple-areola complex (NAC) transposition on a thinned inferior dermal pedicle as an alternative to conventional techniques. METHODS: A retrospective chart review from January 2011 to January 2019 identified a total of 14 male patients who underwent excision of pseudogynecomastia using the described technique. RESULTS: Patients were characterized by age, method of weight loss, pre-weight loss body mass index (BMI), post-weight loss BMI, total weight loss, grade of pseudogynecomastia, and concurrent procedures performed. Patients were followed for a period ranging from 3 months to 1.5 years (average, 8.1 months). Pre-weight loss BMI and post-weight loss BMI averaged 52.0 kg/m2 and 29.6 kg/m2, respectively. The average weight lost was 79.72 kg and the average total amount of tissue removed was 2615 g. All patients had concurrent procedures with an average operative time of 274 minutes. Four out of 14 patients (28.6%) experienced minor complications, which included asymmetry, delayed wound healing, seroma, and hyperpigmentation. There were no wound infections, hematomas, flap necrosis, or dysesthesia. CONCLUSIONS: Due to several cosmetic advantages and low complication profile, our technique using a modified elliptical excision and NAC transfer on an inferior dermal pedicle is an attractive option for treating male chest deformity after MWL.

RESUMEN

Despite the clinical relevance of bottoming out, or pseudoptosis, associated with reduction mammaplasty (RM) its evaluation remains an imprecise science. This study aims to further define the kinetics of postoperative pseudoptosis over an extended period of time, after our previous study investigating pseudoptosis in the early postoperative period. Patients undergoing medial pedicle RM had 3-dimensional photographs taken at year 1 and year 2 intervals postoperatively (year 1 = 300-450 days; year 2 = 700-900 days). Bottoming out was assessed with various 3-dimensional parameters. The total breast volume and the percent tissue distribution in the upper pole of the breast did not change from year 1 to year 2. The anterior-posterior projection as well as vector measurements for internipple distance and sternal notch to nipple distance also remained stable from year 1 to year 2. Although previous data from our group documented the occurrence of bottoming out and continued size reduction over the first postoperative year after breast reduction, the present study shows that pseudoptosis does not seem to occur during the second postoperative year.
