Why Liquidity Matters: A Financial Planning and Investment Discussion for Plastic Surgeons

Plastic surgeons should understand the importance of maintaining liquidity as part of a robust household financial planning and investment strategy. Although investors rightly focus on achieving solid long-term returns, our experience suggests that many plastic surgeons often pay too little attention to liquidity management in their outlook, and some may experience stress as a result. This article discusses why liquidity management matters both in terms of each surgeon's unique career and in the context of today's dynamic investment opportunities and risks. We also discuss how best to understand the trade-offs and costs associated with household debt. Finally, we present simple self-diagnostic questions to help surgeons assess whether their current financial planning addresses key liquidity risks. This article belongs to a series that introduces relevant wealth and investment subjects for practicing plastic surgeons, students in plastic surgery, and support function professionals. This discussion is not meant to be exhaustive nor constitutes investment advice regarding any asset class, strategy, or examples cited herein.

Picking the Right Plane: A Comparison of Total Submuscular, Dual-Plane, and Prepectoral Implant-based Breast Reconstruction

BACKGROUND

Implant-based breast reconstruction has evolved, with a recent resurgence of prepectoral techniques. Comparative reconstructive outcomes and complications have not been fully elucidated among the total submuscular (TSM), dual-plane (DP), and prepectoral planes of implant placement.

METHODS

All immediate implant-based breast reconstructions from March 2017 through August 2019 were retrospectively reviewed. Cases were divided into TSM, DP, and prepectoral cohorts. Demographics, operative techniques, and reconstructive outcomes and complications were compared among groups.

RESULTS

826 cases (510 patients) were identified and divided into TSM (n=392), DP (n=358), and prepectoral (n=76) cohorts. Average follow-up for all patients was 27 months. The prepectoral cohort had a higher average BMI and rate of prior reduction/mastopexy. Overall complications were lowest in the TSM group, though this difference was not statistically significant. Major infection occurred more frequently in the DP group compared to the TSM cohort. The prepectoral cohort had a significantly increased incidence of wound dehiscence than the TSM group, while both the dual-plane and prepectoral groups had higher rates of seroma formation and explantation compared to TSM.

CONCLUSIONS

Overall reconstructive complication rates were comparable among the cohorts. Compared to those undergoing TSM reconstruction, the DP cohort was more likely to develop a major infection or require explantation, while the prepectoral group had significantly higher rates of isolated dehiscence, seroma formation, and explantation. This suggest that the absence of overlying vascularized muscle may lead to an inherent inability to tolerate wound healing complications, though further research is needed to clarify these observations.

Robotic deep inferior epigastric perforator flap harvest in breast reconstruction

INTRODUCTION

Reducing donor site morbidity after deep inferior epigastric artery perforator (DIEP) flap harvest relies mainly upon maintaining integrity of the anterior rectus sheath fascia. The purpose of this study is to describe our minimally-invasive technique for robotic DIEP flap harvest.

METHODS

A retrospective review of four patients undergoing seven robotic-assisted DIEP flaps from 2019 to 2020 was conducted. Average patient age and BMI were 52 years (range: 45-60 years) and 26.7 kg/m² (range: 20.6-32.4 kg/m² ), respectively. Average follow-up was 6.31 months (range: 5.73-7.27 months). Robotic flap harvest was performed with intramuscular perforator dissection in standard fashion, followed by the transabdominal preperitoneal (TAPP) approach to DIEP pedicle harvest using the da Vinci Xi robot. Data was collected on demographic information, perioperative characteristics. Primary outcomes included successful flap harvest as well as donor site morbidity (e.g., abdominal bulge, hernia, bowel obstruction, etc.).

RESULTS

All four patients underwent bilateral abdominally-based free flap reconstruction. Three patients received bilateral robotic DIEP flaps, and one patient underwent unilateral robotic DIEP flap reconstruction. The da Vinci Xi robot was used in all cases. Average flap weight and pedicle length were 522 g (range: 110-809 g) and 11.2 cm (range: 10-12 cm), respectively. There were no flap failures, and no patient experienced abdominal wall donor site morbidity on physical exam.

CONCLUSION

While further studies are needed to validate its use, this report represents the largest series of robotic DIEP flap harvests to date and is a valuable addition to the literature.

A Systematic Review and Meta-Analysis of Microvascular Stacked and Conjoined-Flap Breast Reconstruction

BACKGROUND

 Stacked and conjoined (SC) flaps are a useful means of increasing flap volume in autologous breast reconstruction. The majority of studies, however, have been limited to smaller, single-center series.

METHODS

 A systematic literature review was performed to identify outcomes-based studies on microvascular SC-flap breast reconstruction. Pooled rates of flap and operative characteristics were analyzed. Meta-analytic effect size estimates were calculated for reconstructive complication rates and outcomes of studies comparing SC flaps to non-SC flaps. Meta-regression analysis identified risk factors for flap complications.

RESULTS

 Twenty-six studies were included for analysis (21 case series, five retrospective cohort studies) for a total of 869 patients, 1,003 breasts, and 2006 flaps. The majority of flaps were harvested from the bilateral abdomen (78%, 782 breasts) followed by combined abdomen-thigh stacked flaps (22.2%, 128 breasts). About 51.1% of flaps were anastomosed to anterograde/retrograde internal mammary vessels (230 breasts) and 41.8% used internal mammary/intraflap anastomoses (188 breasts). Meta-analysis revealed a rate of any flap complication of 2.3% (95% confidence interval: 1.4-3.3%), Q-statistic value p = 0.012 (I ² = 43.3%). SC flaps had a decreased risk of fat necrosis compared with non-SC flaps (odds ratio = 0.126, p < 0.0001, I ² = 0.00%), though rates of any flap and donor-site complication were similar. Age, body mass index, flap weight, and flap donor site and recipient vessels were not associated with increased risk of any flap complication.

CONCLUSION

 A global appraisal of the current evidence demonstrated the safety of SC-flap breast reconstruction with low complication rates, regardless of donor site, and lower rates of fat necrosis compared with non-SC flaps.

Optimizing the Mastectomy Flap to Improve Aesthetic Outcomes

The aesthetics of breast reconstruction inherently rely on both the ablative and reconstructive procedures. Mastectomy flap quality remains one of the most critical factors in determining the success of a reconstruction and its aesthetic outcome. Maintaining the segmental perfusion to the nipple and skin envelope during mastectomy requires preserving the subcutaneous tissue superficial to the breast capsule. Because this layer of tissue varies in thickness among different patients and within each breast, anatomic dissection along the appropriate planes is required rather than a "one-size-fits-all" mentality. A team-based approach between the breast surgeon and plastic surgeon will optimize both the ablative and reconstructive procedures while engaging in a process of shared decision-making with the patient. Preoperative clinical analysis and utilization of imaging to assess individual breast anatomy will help guide mastectomies as well as decisions on reconstructive modalities. Critical assessment of mastectomy flaps is paramount and requires flexibility to adapt reconstructive paradigms intraoperatively to minimize the risk of complications and provide the best aesthetic result.

Optimizing Aesthetic Outcomes in Breast Reconstruction After Nipple-Sparing Mastectomy

Nipple-sparing mastectomy (NSM) has been associated with improved quality of life and patient satisfaction with similar oncologic outcomes compared with traditional mastectomy techniques. By conserving the nipple-areola complex and the majority of the breast skin envelope, NSM allows for improved aesthetic outcomes after breast reconstruction. However, the technique is also associated with a steep learning curve that must be considered to achieve optimal outcomes. It is important that the plastic surgeon functions in concert with the extirpative breast surgeon to optimize outcomes because the reconstruction is ultimately dependent on the quality of the overlying mastectomy flaps. Various other factors influence the complex interplay between aesthetic and reconstructive outcomes in NSM, including preoperative evaluation, specific implant- and autologous-based considerations, as well as techniques to optimize and correct nipple-areola complex position. Management strategies for complications necessary to salvage a successful reconstruction are also reviewed. Lastly, techniques to expand indications for NSM and maximize nipple viability as well as preshape the breast are discussed. Through thoughtful preoperative planning and intraoperative technique, ideal aesthetic results in NSM may be achieved.

Comparing outcomes between stacked/conjoined and non-stacked/conjoined abdominal microvascular unilateral breast reconstruction

BACKGROUND

Stacked and conjoined free flaps are increasingly utilized in autologous breast reconstruction to augment tissue transfer volume. However, there is a paucity of comparative data on abdominally-based stacked/conjoined versus non-stacked/conjoined flaps. The purpose of this study was to compare ability to match native breast size, complications, recovery, and symmetrizing procedures between these two cohorts in unilateral breast reconstruction.

METHODS

A retrospective review of all stacked (two separate hemiabdominal)/conjoined (bipedicled full abdominal) flaps and non-stacked/conjoined (unipedicled hemiabdominal) flaps in unilateral abdominally-based autologous breast reconstructions was performed from 2011 to 2018. Variables including demographics, operative characteristics, complications, and revisions were compared in 36 stacked/conjoined patients versus 146 non-stacked/conjoined patients.

RESULTS

The stacked/conjoined cohort had more DIEP flaps (91.7 vs. 65.1%) and the non-stacked/conjoined group more MS-TRAMs (34.2 vs. 6.9%, p = .000). Additionally, non-stacked/conjoined flaps had greater utilization of combined medial and lateral row perforators (p = .000). Mean flap weight was significantly higher than mastectomy weight in stacked/conjoined flaps (+110.7 g) when compared to non-stacked/conjoined flaps (-40.2) (p = .023). Average follow-up was 54.7 ± 27.5 and 54.6 ± 29.3 months, respectively. Stacked/conjoined flaps had lower fat necrosis rates (8.3 vs. 25.4%, p = .039) and had a decreased risk of fat necrosis on multivariable regression analysis (OR 0.278, p = 0.045). There were otherwise no differences in flap, breast, or donor-site complications. Stacked/conjoined flaps also had a lower rate of contralateral breast reduction (p = .041).

CONCLUSION

Stacked/conjoined flaps were associated with a lower risk of fat necrosis compared with non-stacked/conjoined flaps and had a lower rate of contralateral symmetrizing reductions in patients undergoing unilateral abdominally-based breast reconstruction.

Prophylactic nipple-sparing mastectomy in young previvors: Examining decision-making, reconstructive outcomes, and patient satisfaction in BRCA+ patients under 30

Bilateral prophylactic mastectomies (BPM) in young previvors with high-risk mutations are rising; however, little data on management, therapy timing, and outcomes exist. BRCA+ patients under 30 undergoing BPM from 2006 to 2018 were reviewed. Twenty-two patients aged 23-29 underwent mastectomy 4.2 years after genetic diagnosis. Twelve patients completed surveys, most often citing personal decisions (50%) for undergoing mastectomy and plastic surgeons' recommendations (83.3%) for reconstruction. About 73% of patients completely understood risks/benefits of mastectomy and 63.6% of reconstruction. Patients reported high BREAST-Q Satisfaction and Well-Being scores. Continued educational resource development will optimize shared decision-making in the reconstructive process.

The Rich Get Richer: Osseous Chimeric Versatility to the Anterolateral Thigh Flap

BACKGROUND

 The lateral femoral circumflex artery (LFCA) system, which supplies the anterolateral thigh (ALT) flap territory, offers a plethora of tissue types for composite, functional reconstruction. However, the ability to include a reliable and flexible osseous component is limited. Based on cadaveric dissections, we describe an isolated LFCA branch to the femur separate from the vastus intermedius that can be included in ALT flap harvest in cases requiring bony reconstruction.

METHODS

 Cadaveric dissection was undertaken to define the LFCA vascular system with specific dissection of the proximal branches of the descending branch of the LFCA (db-LFCA) to define any muscular, periosteal, and/or osseous branches to the femur.

RESULTS

 Six thighs in four cadavers were dissected. Consistent in all specimens, there was an isolated branch extending distally, medially, and posteriorly from the proximal LFCA and entering the periosteum of the femur. In five specimens, the identified branch to the femur was located approximately 1-cm distal to the rectus femoris branch of the LFCA and approximately 1-cm proximal to a separate branch entering and supplying the vastus intermedius. In one specimen, there was a common trunk. The length of this branch from the origin at the LFCA to insertion into the femoral periosteum was approximately 6 to 8 cm.

CONCLUSION

 There appears to be a consistent and reliable branch to the femur based on the proximal LFCA that may be included in ALT flap harvest, adding even more versatility, as another option in complex cases requiring composite reconstruction, including bone.

Fat Grafting and Breast Augmentation: A Systematic Review of Primary Composite Augmentation

Fat grafting during primary breast augmentation has the ability to address the limitations of soft tissue coverage of breast implants. The purpose of this study was to evaluate the current evidence on patient selection, surgical techniques, and assessment of outcomes with composite breast augmentation.

Strategies and considerations in selecting between subpectoral and prepectoral breast reconstruction

Implant-based breast reconstruction has evolved through advances in mastectomy and reconstruction techniques to offer excellent outcomes with both prepectoral and subpectoral implant placement. Proper patient selection and surgical technique are key for optimizing outcomes and minimizing complications regardless of implant location. Therefore, familiarity with the benefits and limitations of each technique is vital. Several patient characteristics, such as history of significant comorbidities, radiation or active smoking, portend higher risk of complications with prepectoral reconstruction, in which case subpectoral implant placement may be a safer option. Oncologic consideration such as location and size of tumors also play an important role in determining the appropriate technique. The most critical factor in the success of prepectoral reconstruction is the quality of mastectomy flaps. Thorough intraoperative evaluation of mastectomy flap perfusion and viability will determine whether immediate prepectoral reconstruction is possible or other alternatives such as subpectoral or delayed prepectoral techniques should be considered. Discussing these factors with patients preemptively as well as developing a coordinated plan with the patient and oncologic surgeon will maximize success in both subpectoral and prepectoral implant-based reconstruction.

Carpal Tunnel Syndrome Following Corrective Osteotomy for Distal Radius Malunion: A Rare Case Report and Review of the Literature

BACKGROUND

Although median nerve neuropathy and carpal tunnel syndrome (CTS) are known complications of both untreated and acutely treated distal radius fracture, median neuropathy after correction of distal radius malunion is not commonly reported in hand surgery literature. We describe a patient with severe CTS after corrective osteotomy, open reduction internal fixation (ORIF) with a volar locking plate (VLP), and bone grafting for distal radius malunion.

METHODS

We report a case of severe acute CTS as a complication of corrective osteotomy with bone grafting for distal radius malunion.

RESULTS

The patient was treated with surgical exploration of the median nerve and carpal tunnel release.

CONCLUSION

The authors report a case of acute CTS after ORIF with VLP for a distal radius malunion warranting surgical exploration and carpal tunnel release. Treatment teams must be aware of this potential complication so that the threshold for reoperation is low and irreversible damage to the median nerve is prevented.

Breast Milk Feeding Rates in Patients with Cleft Lip and Palate at a North American Craniofacial Center

Objective

Our study goal was to evaluate the rates of breast milk feeding among patients with oral clefts at a large North American Craniofacial Center.

Methods

Parents of patients with oral clefts born from 2000 to 2012 and treated at our center were interviewed regarding cleft diagnosis, counseling received for feeding, and feeding habits.

Results

Data were obtained from parents of 110 patients with oral clefts. Eighty-four percent of parents received counseling for feeding a child with a cleft. Sixty-seven percent of patients received breast milk for some period of time with a mean duration of 5.3 months (range 0.25 to 18 months). When used, breast milk constituted the majority of the diet with a mean percentage of 75%. Breast milk feeding rates increased successively over the 13-year study period. The most common method of providing breast milk was the Haberman feeder at 75% with other specialty cleft bottles composing an additional 11%. Parents who received counseling were more likely to give breast milk to their infant ( P = .02). Duration of NasoAlveolar Molding prior to cleft lip repair did not affect breast milk feeding length ( P = .72). Relative to patients with cleft lip and palate, patients with isolated cleft lip had a breast milk feeding odds ratio of 1.71.

Conclusion

We present breast milk feeding in the North American cleft population. Although still lower than the noncleft population, breast milk feeding with regards to initiation rate, length of time, and proportion of total diet is significantly higher than previously reported.

Abstract P2-12-08: Oncologic outcomes after nipple-sparing mastectomy: A single-institution experience

Introduction: Nipple-sparing mastectomy (NSM) is the latest advancement in the treatment of breast cancer. Long-term oncologic outcomes in nipple-sparing mastectomy (NSM) continue to be defined. Rates of locoregional recurrence for skin-sparing mastectomy (SSM) and NSM in the literature range from 0 to 14.3%. We investigated the outcomes of NSM at our institution.

Methods: Patients undergoing NSM at our institution from 2006 to 2014 were identified. Patient demographics, tumor characteristics, and outcomes were collected. Locoregional recurrence was compared to previously published NSM and SSM results compiled from 14 and 11 studies in the literature. Institutional review board approval was obtained prior to the initiation of this study.

Results: From 2006 to 2014, 319 patients (555 breasts) underwent NSM. 149 patients (248 breasts) had long-term follow-up available. Average patient age and BMI were 47.4 and 24.28. Eighty-five percent of patients underwent mastectomy primarily for a therapeutic indication. Average tumor size was 1.41 centimeters with the most common histologic type being invasive ductal carcinoma (66.7%) followed by DCIS (23.8%). Nodal disease was present in 14.8% of patients. Average patient follow-up was 30.72 months. There was one (0.7%) incidence of ipsilateral chest-wall recurrence in a 44 year-old (p&lt;0.0001, compared to aggregate NSM and SSM data). There were 0.36 complications per patient. There were 3 incidences of nipple-areola complex (NAC) necrosis: 2 partial thickness necrosis and 1 full thickness necrosis.

Nipple-sparing Mastectomy and Sub-areolar Biopsy: To Freeze or not to Freeze? Evaluating the Role of Sub-areolar Intraoperative Frozen Section

Use of nipple-sparing mastectomy (NSM) for risk-reduction and therapeutic breast cancer resection is growing. The role for intraoperative frozen section of the nipple-areolar complex remains controversial. Records of patients undergoing NSM at our institution from 2006 to 2013 were reviewed. Records from 501 nipple-sparing mastectomies were reviewed (216 therapeutic, 285 prophylactic). Of the 480 breasts with sub-areolar biopsies, 307 had intraoperative frozen sections and 173 were evaluated with permanent paraffin section only. Among the 307 intraoperative frozen sections, 12 biopsies were positive on permanent paraffin section (3.9% or 12/307). Of the 12 positive permanent biopsies, five were false negative and the remaining seven concordant intraoperatively. Sensitivity and specificity of sub-areolar frozen section were 0.58 and 1, respectively. Positive sub-areolar biopsies consisted primarily of ductal carcinoma in situ (62% or 13/21). The nipples or nipple-areolar complex were resected in a separate procedure following mastectomy (10/21), intraoperatively following frozen section results (7/21) or during second-stage breast reconstruction (3/21; 1 additional scheduled). Only 30% (6/20) of resected specimens had abnormal residual pathology. Intraoperative frozen section is highly specific and moderately sensitive for the detection of positive sub-areolar biopsies in NSM. Its use can help guide intraoperative reconstructive planning. The presence of positive sub-areolar biopsies in both contralateral and high-risk prophylactic mastectomy specimens emphasizes the need to perform sub-areolar biopsies in all nipple-sparing mastectomies.

Cost Analysis of Intraoperative Subareolar Frozen Section During Nipple-Sparing Mastectomy

BACKGROUND

Permanent paraffin subareolar biopsy during nipple-sparing mastectomy (NSM) tests for occult cancer at the nipple-areolar complex. Intraoperative subareolar frozen section can provide earlier detection intraoperatively. Cost analysis for intraoperative subareolar frozen section has never been performed.

METHODS

NSM cases from 2006-2013 were reviewed. Patient records including financial charges were analyzed.

RESULTS

Of 480 subareolar biopsies for NSM from 2006-2013, 21 were abnormal (4.4 %). A total of 307 of the subareolar biopsies included intraoperative frozen section. Of the 307, 12 (3.9 %) were abnormal with 7 of 12 detected on intraoperative frozen section. The median baseline charge for an intraoperative subareolar frozen section was $309 for an estimated total cost of $94,863 in 307 breasts. The median baseline charge for interval operative resection of a nipple-areolar complex following an abnormal subareolar pathology result was $11,021. Intraoperative subareolar biopsy avoided an estimated six return trips to the operating room for savings of $66,126. At our institution, routine use of intraoperative frozen section resulted in an additional $28,737 in healthcare charges or $95 per breast.

CONCLUSIONS

We present the first cost analysis to evaluate intraoperative subareolar frozen section in NSM. This practice obviated an estimated six return trips to the operating room. With our institutional frequency of abnormal subareolar pathology, intraoperative frozen sections resulted in a marginal increased charge per mastectomy.

Reconstructive approach for patients with augmentation mammaplasty undergoing nipple-sparing mastectomy

BACKGROUND

Nipple-sparing mastectomy (NSM) is a recent advance in the therapeutic and prophylactic management of breast cancer; however, the procedure is associated with increased reconstructive complications. Data on NSM after previous breast augmentation are limited.

OBJECTIVES

The authors compared reconstructive complications after NSM between patients with previously augmented breasts and a larger cohort that had not undergone prior augmentation. An approach to NSM that involves 2-stage reconstruction in augmented patients is also described.

METHODS

Medical records of NSMs performed at New York University Langone Medical Center from 2006 to 2013 were reviewed. Data points evaluated included patient characteristics, comorbidities, breast implant plane, and reconstructive complications. Fisher's exact and t tests were used for the comparisons.

RESULTS

During the study period, NSMs were performed in 17 augmented breasts at this institution. After NSM, 15 of these breasts underwent implant-based reconstruction and 2 breasts underwent microvascular free flaps. Reconstructive complications included 1 hematoma managed nonoperatively (5.9%) and 1 partial necrosis of the nipple-areola complex (NAC) (5.9%). Compared with the larger nonaugmented cohort (n=332), patients with previously augmented breasts had fewer complications, and there were no statistically significant differences in the rates of mastectomy flap necrosis, partial NAC necrosis, complete NAC necrosis, hematoma, capsular contracture, explantation, implant displacement, seroma, or breast cellulitis.

CONCLUSIONS

The results indicate that NSM reconstruction is associated with minimal complications in patients with previous augmentation mammaplasty.

Effects of experience on size discrimination and attitudes toward the Susan B. Anthony coin

Effects of experience with the Susan B. Anthony dollar on size discrimination and attitudes toward the coin were investigated. Those who used the coin for 4 wk. were quite accurate in discriminating its size visually while those without experience confused the size of the dollar coin with the size of the quarter. On a coin-selection task experienced subjects were no more accurate than inexperienced subjects but differed in type of error, confusing the dollar coin with the half-dollar coin more frequently. In contrast, the errors of inexperienced subjects were unsystematic. No attitudinal changes resulting from experience with the coin were found.
