Craniofacial Distraction Osteogenesis

Distraction osteogenesis (DO) of the craniofacial skeleton has become an effective technique for the treatment of both nonsyndromic and syndromic conditions. The advent of craniofacial DO has allowed for earlier intervention in pediatric patients with less complication risk and morbidity compared to traditional techniques. In this review, we will discuss current application and technique for craniofacial DO by anatomical region and explore future applications in craniofacial surgery.

Extracorporeal Pedicles for Free Flap Reconstruction in Diabetic Lower Extremity Wounds

Diabetic foot ulcers are a severe complication of diabetes, and their management requires a multidisciplinary approach for optimal management. When treating these ulcers, limb salvage remains the ultimate goal. In this article, we present the “hanging” free flap for the reconstruction of chronic lower extremity diabetic ulcers. This two-staged approach involves standard free flap harvest and inset; however, following inset the “hanging” pedicle is covered within a skin graft instead of making extraneous incisions within the undisturbed soft tissues or tunnels that can compress the vessels. After incorporation, a second-stage surgery is performed in 4 to 6 weeks which entails pedicle division, flap inset revision, and end-to-end reconstruction of the recipient vessel. Besides decreasing the number of incisions on diabetic patients, our novel technique utilizing the “hanging” pedicle simplifies flap monitoring and inset and allows reconstruction of recipient vessels to reestablish distal blood flow.

Strategies to Minimize Surgical Scarring: Translation of Lessons Learned from Bedside to Bench and Back

Significance: An understanding of the physiology of wound healing and scarring is necessary to minimize surgical scar formation. By reducing tension across the healing wound, eliminating excess inflammation and infection, and encouraging perfusion to healing areas, surgeons can support healing and minimize scarring. Recent Advances: Preoperatively, newer techniques focused on incision placement to minimize tension, skin sterilization to minimize infection and inflammation, and control of comorbid factors to promote a healing process with minimal scarring are constantly evolving. Intraoperatively, measures like layered closure, undermining, and tissue expansion can be taken to relieve tension across the healing wound. Appropriate suture technique and selection should be considered, and finally, there are new surgical technologies available to reduce tension across the closure. Postoperatively, the healing process can be supported as proliferation and remodeling take place within the wound. A balance of moisture control, tension reduction, and infection prevention can be achieved with dressings, ointments, and silicone. Vitamins and corticosteroids can also affect the scarring process by modulating the cellular factors involved in healing. Critical Issues: Healing with no or minimal scarring is the ultimate goal of wound healing research. Understanding how mechanical tension, inflammation and infection, and perfusion and hypoxia impact profibrotic pathways allows for the development of therapies that can modulate cytokine response and the wound extracellular microenvironment to reduce fibrosis and scarring. Future Directions: New tension-off loading topical treatments, laser, and dermabrasion devices are under development, and small molecule therapeutics have demonstrated scarless wound healing in animal models, providing a promising new direction for future research aimed to minimize surgical scarring.

Patents for the Plastic Surgeon: A Primer

ABSTRACT

Although innovation and entrepreneurship are complementary in the process of creating new products, plastic surgeons are frequently discouraged by the challenges associated with the regulatory and administrative environments in patent filing. The following primer provides a step-by-step guide for understanding patents and outlines the steps and costs involved in patent filing. To improve opportunities for successful patent filing, we elaborate on some of the common pitfalls in the process, including the timing of public disclosure, conducting a private art search, selecting a patent attorney or agent, determining the level of inventor involvement, and navigating academic and employment contracts. The innovative drive in plastic surgery provides a strong impetus for strengthening knowledge about patents and patent filing in order to support efforts for providing high-value patient care.

Employment as a Plastic Surgeon: A Review of Trends and Demand Across the Field

ABSTRACT

Intrinsic to the field of plastic surgery, constant changes in health care policy, consumer demands, and medical technology necessitate periodic evaluation of trends in employment over time. In this article, we review the existing literature to report the current state of plastic surgery employment in the United States with regards to compensation, practice patterns, subspecialty trends, contract negotiation, representation of women in the field of plastic surgery, burnout and job satisfaction, and retirement. Understanding how the plastic surgery job market is changing not only serves as a valuable tool for the individual plastic surgeon regarding the navigation of his or her own career but also offers insight into the future of the field as a whole.

Cost-effectiveness of Multidisciplinary Care in Plastic Surgery: A Systematic Review

BACKGROUND

Multidisciplinary care has been previously shown to improve outcomes for patients and providers alike, fostering interprofessional collaboration and communication. Many studies have demonstrated the beneficial health care outcomes of interdisciplinary care. However, there has been minimal focus on the cost-effectiveness of such care, particularly in the realm of plastic surgery. This is the first systematic review to examine cost savings attributable to plastic surgery involvement in multidisciplinary care.

METHODS

A comprehensive literature review of articles published on cost outcomes associated with multidisciplinary teams including a plastic surgeon was performed. Included articles reported on cost outcomes directly or indirectly attributable to a collaborative intervention. Explicitly reported cost savings were totaled on a per-patient basis. Each article was also reviewed to determine whether the authors ultimately recommended the team-based intervention described.

RESULTS

A total of 604 articles were identified in the initial query, of which 8 met the inclusion criteria. Three studies reported explicit cost savings from multidisciplinary care, with cost savings ranging from $707 to $26,098 per patient, and 5 studies reported changes in secondary factors such as complication rates and length of stay. All studies ultimately recommended multidisciplinary care, regardless of whether cost savings were achieved.

CONCLUSIONS

This systematic review of the cost-effectiveness of multidisciplinary plastic surgery care examined both primary cost savings and associated quality outcomes, such as length of stay, complication rate, and resource consumption. Our findings indicate that the inclusion of plastic surgery in team-based care provides both direct and indirect cost savings to all involved parties.

Bringing Your Idea to the Market: A Primer for Plastic Surgeons

SUMMARY

The progress of biotechnology, medical instruments, and applied sciences contributes to a rapidly expanding space for the advancement of the medical field. Surgeons experience first-hand the limitations of current medical devices and thus have unique insight into problems that could be solved with new products. The process of turning an idea into a product capable of success in the marketplace, however, is often unfamiliar to surgeons. The authors seek to illuminate this process and provide an ordered list of tasks that can make bringing ideas to market more achievable for surgeons. The first step in this process is the generation and protection of a new idea. Next, the process of making an idea into a product is outlined. This phase involves team assembly, business planning, and product development. Market research and valuation are key to understanding how a product can be applied in the market, and meticulous research during this phase allows for informed decision-making that will help secure funding down the road. Finally, various options for financing are discussed and compared to help surgeon-entrepreneurs find an option that best fits their project, and steps to maximize leverage are described. The development of new products can be a complicated process for surgeons. Organized into four phases, with ordered instructional steps to advance through each phase, the process of bringing an idea to the market is clarified. Facilitating this process will possibly contribute to the continual improvement of medical and surgical abilities through the introduction of new devices and technologies.

A Systematic Review of Wellness in Plastic Surgery Training

BACKGROUND

Physician and resident wellness has been increasingly emphasized as a means of improving patient outcomes and preventing physician burnout. Few studies have been performed with a focus on wellness in plastic surgery training.

OBJECTIVES

The aim of this study was to systematically review what literature exists on the topic of wellness in plastic surgery training and critically appraise it.

METHODS

A PubMed search was performed to identify journal articles related to wellness in plastic surgery residency. Seventeen studies (6 cohort and 11 cross-sectional) met inclusion criteria and were appraised with the Newcastle-Ottawa Quality Assessment Scale (NOQAS) to determine the quality of the studies based on selection, comparability, and outcome metrics.

RESULTS

Critical assessment showed that the studies were highly variable in focus. Overall, the quality of the data was low, with an average NOQAS score of 4.1. Only 2 studies focused on plastic surgery residents, examining work hours and social wellness, respectively; they were awarded NOQAS scores of 3 and 4 out of 10.

CONCLUSIONS

The results of this systematic review suggest that little research has been devoted to wellness in surgery training, especially in regard to plastic surgery residents, and what research that has been performed is of relatively low quality. The available research suggests a relatively high prevalence of burnout among plastic surgery residents. Evidence suggests some organization-level interventions to improve trainee wellness. Because outcomes-based data on the effects of such interventions are particularly lacking, further investigation is warranted.

Vascularized Bone Grafts for Spinal Fusion-Part 3: The Occiput

BACKGROUND

Obtaining successful arthrodesis at the craniocervical junction and atlantoaxial joint can be more challenging than in other segments of the cervical spine. This challenge stems from the relatively hypermobile joints between the occipital condyles, the motion that occurs at C1 and C2, as well as the paucity of dorsal bony surfaces for posterior arthrodesis. While multiple different techniques for spinal fixation in this region have been well described, there has been little investigation into auxiliary methods to improve fusion rates.

OBJECTIVE

To describe the use of an occipital bone graft to augment bony arthrodesis in the supraaxial cervical spine using a multidisciplinary approach.

METHODS

We review the technique for harvesting and placing a vascularized occipital bone graft in 2 patients undergoing revision surgery at the craniocervical junction.

RESULTS

The differentiation from nonvascularized bone graft, either allograft or autograft, to a bone graft using vascularized tissue is a key principle of this technique. It has been well established that vascularized bone heals and fuses in the spine better than structural autogenous grafts. However, the morbidity and added operative time of harvesting a vascularized flap, such as from the fibula or rib, precludes its utility in most degenerative spine surgeries.

CONCLUSION

By adapting the standard neurosurgical procedure for a suboccipital craniectomy and utilizing the tenets of flap-based reconstructive surgery to maintain the periosteal and muscular blood supply, we describe the feasibility of using a vascularized and pedicled occipital bone graft to augment instrumented upper cervical spinal fusion. The use of this vascularized bone graft may increase fusion rates in complex spine surgeries.

Vascularized Bone Grafts for Spinal Fusion-Part 2: The Rib

BACKGROUND

Pseudoarthrosis, or failure to achieve bony union, is a well-known complication of spinal fusion operations. Rates range from 5% to 40% and are influenced by both patient and technical factors. Patients who do not achieve complete fusion may experience a return or worsening of their preoperative pain. For patients with complicated pathologies, vascularized bone grafts (VBGs) have been shown to provide better outcomes than nonvascularized bone grafts (N-VBGs).

OBJECTIVE

To enhance an instrumented spinal fusion by the innovative technique presented herein that utilizes a rotated, pedicled VBG from the left eighth rib under the paraspinous musculature into the midlumbar posterolateral gutter.

METHODS

For posterior approaches, the rib can be easily accessed and rotated into the appropriate strut position. The rib is dissected out, identifying and preserving the neurovascular bundle medially. The rib is then tunneled medially and appropriately positioned as the spinal graft, with the curve providing anatomic kyphosis or lordosis, depending on the surgical location. It is then successfully fixated with plates and spinal screws.

RESULTS

In our limited experience to date, vascularized rib grafting procedures augment fusion and reduce operating room time and bleeding compared to free flap procedures. No patients have experienced complications related to these grafts.

CONCLUSION

Pedicled vascularized rib grafts can be utilized to provide the advantages of a vascularized bone flap in complicated pathologies requiring spinal fusion as far as the L2-L3 level, without the morbidity associated with free tissue transfer.

Vascularized Bone Grafts for Spinal Fusion-Part 4: The Scapula

BACKGROUND

Solid arthrodesis is the long-term goal of most spinal reconstruction surgeries. A multitube of biologics as well as autograft is commonly used to augment the bony fusion. Medial scapular vascularized bone grafts (S-VBGs) are a novel approach to supplement cervicothoracic arthrodesis in patients at high risk for failed fusion.

OBJECTIVE

To discuss the benefits of using a vascularized scapular graft, pedicled to the rhomboid minor, compared to both nonvascularized bone grafts and free vascularized bone grafts, as well as the surgical technique, feasibility, and nuances of the surgical experience with an S-VBG.

METHODS

The anatomic feasibility of this procedure has been established in cadaver studies. This technical note details the operative steps and presents the first surgery in which a vascularized scapular graft was used to supplement cervicothoracic arthrodesis.

RESULTS

A single patient with complex cervical deformity was successfully treated with this novel arthrodesis approach.

CONCLUSION

Vascularized scapula grafts, pedicled on the rhomboid minor, provides both structural support and a source of vascularized autograft to a cervicothoracic arthrodesis. It leverages the benefits of a free-flap bone with less operative time and morbidity.

Vascularized Bone Grafts for Spinal Fusion-Part 1: The Iliac Crest

BACKGROUND

Iliac crest autograft has been the gold standard for harvest of fusion materials in spine surgery. The benefits of a vascularized version of this bone graft-including delivery of stem cells, ability to deliver antibiotics to the fusion bed, and relative ease of harvest-make this technique superior to free bone transfer in the achievement of augmented spinal fusion.

OBJECTIVE

To present a brief summary of similar existing concepts before describing the novel technique of this vascularized posterior iliac crest bone graft.

METHODS

Vascularized posterior iliac crest bone graft can be harvested from the same midline lumbar incision used for thoracolumbar spinal fusion, through lateral dissection around the paraspinals to the iliac crest. Recipient sites in the posterolateral bony spinal gutters may be as rostral as T12 and caudal as the sacrum. The ability to cover multiple lumbar levels can be achieved with desired lengths of the donor iliac crest.

RESULTS

Over 14 vascularized iliac crest bone grafts have been performed to augment lumbar fusion for salvage after pseudoarthrosis. Operative time and bleeding are reduced compared to free flap procedures, and no patients have experienced any complications related to these grafts. Indocyanine green (ICG) angiography has been utilized in a novel way to ensure the vascularity of the bone graft prior to arthrodesis.

CONCLUSION

While long-term follow-up will be required to fully characterize fusion rates and patient morbidity, this innovative surgical option augments spinal fusion in patients with, or at increased risk for, pseudoarthrosis.

Microbiology of Implant-Based Breast Reconstruction Infections: A Systematic Review

BACKGROUND

Postsurgical complications have been an increasing concern for hospitals, particularly in light of payment reform. The costs to the health care system are increasing in light of Medicare penalties for readmissions for certain conditions. Surgical site infection following implant-based breast reconstruction (IBR) remains challenging. The rates of positive cultures and isolated microorganisms in IBR are unknown. This systematic review summarizes the reported microorganisms and positive culture rates in the existing literature.

METHODS

A systematic review was performed using the guidelines outlined in Preferred Reporting Items for Systematic Reviews and Meta-analyses. Articles were included if breast implant infection rates and culture results were reported. Further subgroup analysis of culture positive infections was performed.

RESULTS

A total of 25 studies were included, encompassing 25,177 IBR. Implant infections were reported in 1356 reconstructions (5.4%). Cultures were positive in 74.5% of infections. Gram-positive bacteria were the most common (68.6%), of which Staphylococcus species (51%) was the most isolated pathogen, followed by Pseudomonas. A subgroup analysis showed that early infections (63% vs 88%), radiotherapy (82% vs 93%), and acellular dermal matrix use (90% vs 100%) were associated with lower positive culture rates than their respective counterparts. Patients who received chemotherapy had higher positive culture results (94% vs 83%). Isolated microorganisms also varied among the subgroups.

CONCLUSIONS

This systematic review outlines reported microorganisms in IBR. Staphylococcus species and Pseudomonas were the most frequently reported microorganism. Negative cultures were reported in up to 25.5% of infections. Patients with early infections, radiotherapy, and acellular dermal matrix demonstrated higher negative culture rates. This review can help guide the use of empirical antimicrobial therapy in IBR.

Vascularized Rib Bone Grafting: Indications, Techniques, and Clinical Outcomes

Pseudarthrosis is a difficult complication often seen in patients with complex spinal pathology. To supplement existing neurosurgical approaches to cervicothoracic spinal instrumentation and fusion, novel vascularized rib bone grafts can be utilized in patients at high risk for failed spinal fusion. In this article, we discuss the indications, benefits, surgical technique, feasibility, and limitations of using rib vascularized rib bone grafts to augment spinal fusion.

Vascularized Occipital Bone Grafting: Indications, Techniques, Clinical Outcomes, and Alternatives

Successful arthrodesis at the craniocervical junction and atlantoaxial joint can be more challenging than in other segments of the cervical spine. Different techniques for spinal fixation in this region have been well described, along with auxiliary methods to improve fusion rates. The occipital vascularized bone graft is a novel technique that can be used to augment bony arthrodesis in the supra-axial cervical spine. It provides the benefits of a vascularized autologous graft, such as accelerated healing, earlier fusion, and increased strength. This technique can be learned with relative ease and may be particularly helpful in cases with high risk of nonunion or pseudoarthrosis in the upper cervical spine.

Vascularized Scapular Bone Grafting: Indications, Techniques, Clinical Outcomes, and Alternatives

Spinal fusion can be challenging to obtain in patients with complex spinal pathology. Medial scapular vascularized bone grafts (S-VBGs) are a novel approach to supplement cervicothoracic arthrodesis in patients at high risk of failed spinal fusion. In this article, we discuss the benefits of using VBGs compared with both nonvascularized bone grafts and free vascularized bone flaps and the surgical technique, feasibility, and limitations specific to the S-VBG.

The Historical Role of the Plastic Surgeon in Spine Reconstruction

Wound complications occur in up to 19% of patients undergoing complex spine surgery. The role of the plastic surgeon in complex and redo spine surgery is important and evolving. Classically, plastic surgeons have been involved in the management of patients who develop wound complications following surgery. This involves reconstruction of posterior trunk defects with locoregional fasciocutaneous, muscle, and free tissue transfers. There has also been an increasing role for plastic surgeons to become involved in prophylactic closures of complex and/or redo spine surgeries for high-risk populations. Identification of patients with comorbidities and likelihood for multiple reoperations who are prophylactically treated with complex closure with or without local muscle flaps could significantly decrease the postoperative wound complications.

Vascularized Posterior Iliac Crest Bone Grafting: Indications, Techniques, Clinical Outcomes, and Alternatives

Pseudarthrosis is a feared complication of spinal fusion procedures. Currently, the gold standard in prevention or treatment of pseudarthrosis is placement of nonvascularized iliac crest bone autograft. While rates of fusion are significantly higher in patients with use of nonvascularized bone autografts than with allografts, patients who have previously failed lumbar arthrodesis or those at a high risk for pseudarthrosis may benefit from a more robust, vascularized bone graft with enhanced osteogenicity. In this article, we discuss the use of iliac crest vascularized bone grafts as an adjunct for high-risk patients undergoing lumbosacral spine arthrodesis.

Distraction Osteogenesis: Mandible and Maxilla

Mandibular and maxillary deformities commonly require surgical intervention. Prior to distraction osteogenesis, traditional modalities involving single-staged translocation and rigid fixation were used to correct these craniofacial anomalies. Distraction osteogenesis has evolved as a compelling alternative for treating aesthetic and functional dentofacial defects. The process of distraction osteogenesis involves three phases-latency, activation, and consolidation-which allow for appropriate translation of the affected craniofacial skeleton. This review will cover the role of distraction for managing congenital and acquired deformities of the mandible and maxilla. This novel technique can be performed at numerous anatomical sites along the craniofacial skeleton to treat a variety of anomalies, which serves as a testament to its adaptability and efficacy. Importantly, distraction osteogenesis also has the ability to simultaneously increase bone length and the overlying soft tissue envelope. This advantage results in larger advancements with reduced relapse rates and improved patient satisfaction. While complications remain a concern, it stands to reason that the measurable benefits observed underscore the power and versatility of distraction osteogenesis.

Use of Single Chimeric Free Flaps or Double Free Flaps for Complex Head and Neck Reconstruction

BACKGROUND

 Free flaps have become the preferred reconstructive approach to restore form and function for patients presenting with complex head and neck defects. For composite, complex defects for which a regular free flap might not meet all reconstructive demands, adequate coverage can be achieved with either a single chimeric free flap or a double free flap.

METHODS

 We performed a single-center retrospective chart review of patients who underwent either single chimeric free flap or double free flap reconstruction. Indications for reconstruction included defects resultant from head and neck tumor or osteoradionecrosis resections. We extracted the following variables: tumor location, defect, flap(s) performed, and postoperative complications. Unpaired t-tests were performed to evaluate for statistically significant differences in complications encountered between the single chimeric versus the double free flap patient groups.

RESULTS

 In our series of 44 patients, a total of 55 single chimeric and double free flaps were performed. We found no significant difference in overall complications (p = 0.41) or flap/skin paddle loss (p = 0.45) between the groups. There were three total flap losses; two patients underwent successful salvage procedures and one patient died. The anterolateral thigh (ALT) was the most common free flap (70%) used in our series, and 98% of our patients completed successful reconstruction.

CONCLUSION

 As the initial reconstructive effort is critical for achieving favorable long-term outcomes in complex head and neck cases, effective and safe techniques should be employed to ensure optimal delivery of care. We believe that single chimeric and double free flap techniques should be appropriately utilized as part of the armamentarium of head and neck reconstructive microsurgeons.

Health Care Services Utilization by Transgender Patients in a Medicaid Managed Program

While challenges related to health care utilization among transgender individuals have been discussed, studies examining health services under Medicaid are limited. A retrospective review was performed on all patients who presented with Gender Dysphoria from 2013-2018 to one Medicaid managed program. Utilization rates of distinct services and interventions were analyzed. A total of 192 patients, with 787 encounters, were identified. Mean patient age was 15 years old. Mean number of encounters per patient was 4.1. The average number of distinct specialties seen was 1.4. Behavioral health (BH) services were most commonly utilized (50%). Endocrinology and surgical services were encountered less frequently. Medications were prescribed for 25% of patients; hormonal treatment was prescribed for 6.7%. This study highlights the deficiencies in services this population is receiving under one managed Medicaid program. While behavioral health services are widely employed, underutilization of medical and surgical consultations compromises patient awareness of available interventions.

Multidisciplinary management of a previously unreported presentation of severe aplasia cutis congenita

Aplasia cutis congenita (ACC) is characterized by the complete or partial absence of skin at birth, with 85% of cases of ACC involving the scalp vertex. The etiology of ACC is unclear and appears to be multifactorial. We present the case of a 3-month-old boy who presented with a diagnosis of non-scalp ACC affecting approximately 80% of his total body surface area at birth. This case adds to the literature due to the patient's survival beyond the first day of life and his unique and severe distribution of defects, which led to respiratory compromise and required multidisciplinary management.

Pediatric Fronto-Orbital Skull Reconstruction

Craniofacial surgery in children is a highly challenging discipline that requires extensive knowledge of craniofacial anatomy and pathology. Insults to the fronto-orbital skeleton have the potential to inflict significant morbidity and even mortality in patients due to its proximity to the central nervous system. In addition, significant aesthetic and ophthalmologic disturbances frequently accompany these insults. Craniosynostosis, facial trauma, and craniofacial tumors are all pathologies that frequently affect the fronto-orbital region of the craniofacial skeleton in children. While the mechanisms of these pathologies vary greatly, the underlying principles of reconstruction remain the same. Despite the limited data in certain areas of fronto-orbital reconstruction in children, significant innovations have greatly improved its safety and efficacy. It is imperative that further investigations of fronto-orbital reconstruction are undertaken so that craniofacial surgeons may provide optimal care for these patients.

Multidisciplinary care in surgery: Are team-based interventions cost-effective?

BACKGROUND

Multidisciplinary care has been shown to improve outcomes for patients, and interprofessional collaboration has been demonstrated to be beneficial for providers. In the field of surgery, although a large number of multidisciplinary care teams have been described, no study to date has examined whether or not these team-based interventions are generally cost-effective. This is the first systematic review to examine cost savings attributable to multidisciplinary care across all surgical fields.

METHODS

A comprehensive literature review of articles published on cost outcomes associated with multidisciplinary surgical teams was performed. Selected articles reported on cost outcomes directly attributable to a collaborative intervention. Cost savings were totaled on a per-patient basis. Each article was also reviewed to determine whether the authors ultimately recommended the team-based intervention described.

RESULTS

A total of 1421 articles were identified in the initial query, of which 43 met inclusion criteria. Thirty-nine studies (91%) reported multidisciplinary care to be cost effective, with an average cost savings among all studies of $5815 per patient. No significant differences in the amount of savings achieved were found between different intervention subtypes. All studies ultimately recommended (40) or gave mixed reviews (3) of multidisciplinary care, regardless of whether cost savings were achieved.

CONCLUSION

Multidisciplinary surgical care is beneficial not only in terms of patient and provider outcomes, but also in reference to its cost-effectiveness. Well-designed multidisciplinary teams tend to optimize perioperative care for all involved parties. Efforts to improve surgical care should employ multidisciplinary teams to promote both quality and cost-effective care.

The Advent of Spinoplastics: Easing the Growing Global Disease Burden of Spinal Injury

Epidemiologic studies have demonstrated a growing global disease burden of pathologies affecting the vertebral column. Allograft or implant-based reconstruction and fusion surgeries have been the mainstay of treatment. The efficacy of various surgical methods and the reliability of instrumentation or implants to execute these surgeries continue to be debated in the literature. Advances such as the free-tissue transfer have improved postoperative measures; however, they add high operative risk. The advent of spinoplastics introduces a practical surgical model to augment these spinal surgeries using vascularized bone grafts. As this technique becomes more widespread, it can be utilized to ease the growing disease burden that spinal injury places on both patients and the health care system. Ultimately, it will ameliorate strains on health care resources, reduce health care costs, and improve patient outcomes and quality of life.

Foreign Body Reaction to Poly-D-L-Lactic Acid Resorbable Plates Used in Craniofacial Surgery

Resorbable surgical materials are often used in the pediatric population to provide fixation in the growing skeleton. Although foreign body reactions to poly-D-L-lactic acid (PDLLA) plates and screws have been previously reported in other fields, to date PDLLA polymers have been well-tolerated in the setting of craniofacial surgery. The authors report a case of a previously healthy 4-month-old patient with Crouzon syndrome who underwent a frontal-orbital advancement with resorbable PDLLA plates and screws and subsequently experienced extensive foreign body reactions and wound healing complications.

Perforator Mapping of the Profunda Artery Perforator Flap: Anatomy and Clinical Experience

BACKGROUND

Discovering alternatives to workhorse flaps that have more consistent anatomy and lower donor-site morbidity has become a focus of reconstructive surgery research. This study provides a simplified approach to profunda artery perforator flap design and harvest based on reliable anatomical landmarks.

METHODS

A retrospective review was conducted of 70 patients who underwent 83 profunda artery perforator flap reconstructions for postoncologic defects from 2016 to 2018. The authors recorded and analyzed the profunda artery perforator flap sizes and clinical applications, the numbers and locations of the perforators, and the patient outcomes.

RESULTS

Most of the profunda artery perforator flaps were for head and neck [46 patients (65.7 percent)] and breast [21 patients (30 percent)] reconstructions. Flaps were most commonly based on perforator A (33.7 percent) and perforator B (33.7 percent), followed by perforators B and C combined (18.1 percent). Perforators were located a mean of 7.5 cm (perforator A), 12.7 cm (B), and 17.6 cm (C) distal to the pubic tubercle parallel to the axis between the pubic tubercle and the medial femoral condyle and 7.9 cm (A), 7.3 cm (B), and 6.1 cm (C) posterior from the axis. There was no flap loss. One patient underwent successful salvage surgery after arterial flap thrombosis. Eight patients (9.6 percent) developed superficial wound dehiscence that was managed conservatively.

CONCLUSIONS

Perforator mapping demonstrated consistent anatomical locations of sizeable profunda artery perforators in the inner thigh. Along with its consistent and robust vascular anatomy and minimal donor-site morbidity, the profunda artery perforator flap's volume and pliability make it a reliable option for soft-tissue reconstruction.

CLINICAL QUESTION/LEVEL OF EVIDENCE

Therapeutic, IV.

Craniofacial phenotypes associated with Robinow syndrome

Robinow syndrome is characterized by mesomelic limb shortening, hemivertebrae, and genital hypoplasia. Due to low prevalence and considerable phenotypic variability, it has been challenging to definitively characterize features of Robinow syndrome. While craniofacial abnormalities associated with Robinow syndrome have been broadly described, there is a lack of detailed descriptions of genotype-specific phenotypic craniofacial features. Patients with Robinow syndrome were invited for a multidisciplinary evaluation conducted by specialist physicians at our institution. A focused assessment of the craniofacial manifestations was performed by a single expert examiner using clinical examination and standard photographic images. A total of 13 patients with clinical and molecular diagnoses consistent with either dominant Robinow syndrome (DRS) or recessive Robinow syndrome (RRS) were evaluated. On craniofacial examination, gingival hyperplasia was nearly ubiquitous in all patients. Orbital hypertelorism, a short nose with anteverted and flared nares, a triangular mouth with a long philtrum, cleft palate, macrocephaly, and frontal bossing were not observed in all individuals but affected individuals with both DRS and RRS. Other anomalies were more selective in their distribution in this patient cohort. We present a comprehensive analysis of the craniofacial findings in patients with Robinow Syndrome, describing associated morphological features and correlating phenotypic manifestations to underlying genotype in a manner relevant for early recognition and focused evaluation of these patients.

Extremity anomalies associated with Robinow syndrome

Robinow syndrome, a rare genetic disorder, is characterized by skeletal dysplasia with, among other anomalies, extremity and hand anomalies. There is locus heterogeneity and both dominant and recessive inheritance. A detailed description of associated extremity and hand anomalies does not currently exist due to the rarity of this syndrome. This study seeks to document the hand anomalies present in Robinow syndrome to allow for improved rates of timely and accurate diagnosis. A focused assessment of the extremities and stature was performed using clinical examination and standard photographic images. A total of 13 patients with clinical and molecular diagnosis consistent with dominant Robinow syndrome or recessive Robinow syndrome were evaluated. All patients had limb shortening, the most common of which was mesomelia; however, rhizomelia and micromelia were also seen. These findings are relevant to clinical characterization, particularly as Robinow syndrome has classically been defined as a "mesomelic disorder." A total of eight distinct hand anomalies were identified in 12 patients with both autosomal recessive and dominant forms of Robinow syndrome. One patient did not present with any hand differences. The most common hand findings included brachydactyly, broad thumbs, and clinodactyly. A thorough understanding of the breadth of Robinow syndrome-associated extremity and hand anomalies can aid in early patient identification, improving rates of timely diagnosis and allowing for proactive management of sequelae.

A Case of an Aggressive Intraosseous Arteriovenous Malformation in the Lower Extremity: Special Considerations for Diagnosis and Management

BACKGROUND

Arteriovenous malformations (AVMs) are rare, congenital vascular anomalies. Intraosseous AVMS most frequently arise in the head and neck, with only a small fraction occurring in the extremities. Herein, we report the findings of a combined soft tissue and intraosseous AVM involving the lower extremity of a 13-year-old child. This case highlights the necessity of an interdisciplinary approach for the effective treatment and management of these rare vascular anomalies.

CASE DESCRIPTION

A 13-year-old female presented with a 4-year history of intermittent pain and swelling over her right lateral malleolus. The patient was evaluated with radiologic imaging revealing an AVM involving the right distal leg, ankle, and hindfoot with intraosseous involvement of the distal tibia and talus. She was then referred to Vascular and Plastic Surgery and an angiogram was performed demonstrating shunting from the anterior tibial, peroneal, and posterior tibial arteries to the AVM. Venous drainage was to the anterior tibial and greater saphenous veins. Three embolizations were performed over the course of 6 months. Following the third embolization, the patient was taken to the operating room where Plastic and Orthopedic Surgery performed total resection of the nidus and involved bone which was then grafted with injectable synthetic bone graft.

RESULTS

Successful resection of the nidus was achieved, and the patient had an uncomplicated recovery. Within 6 months postoperatively, the patient demonstrated full range of lower extremity motion and was able to participate in age appropriate gross motor activities. Radiologic evaluation 7 months postoperatively showed no evidence of nidus recurrence.

CONCLUSION

Intraosseous involvement of AVMS is rare and presents a therapeutic challenge due to its invasive potential and high incidence of recurrence. Wide local excision with bone grafting and interdisciplinary management are paramount for complete resection.

Use of Simulation in Plastic Surgery Training

The nationwide focus on patient safety and the health of residents has increased the demand for educational tools outside the operating room. Simulation is a valuable tool for assessing and developing surgical skills in a controlled and safe environment. The use of simulation as a formal component of training has been increasing in various surgical subspecialties. In general surgery, simulation examinations such as the Fundamentals of Laparoscopic Surgery and Fundamentals of Endoscopic Surgery have become a prerequisite to board certification. Although formal simulation examinations in plastic surgery are not universal, there has been an increase in the use of simulation to increase resident competency in the operating room. For now, we will review the current state of simulation in craniofacial, hand, microvascular, and esthetic surgery and discuss applications for the future. We will also discuss the evolving role of artificial intelligence, virtual reality, and augmented reality in plastic surgery training and testing.

Aesthetic Training in Plastic Surgery Residency

Training in aesthetic surgery is a core element in a plastic surgery residency program. Nevertheless, in the past, many studies have shown the lack of resident confidence in aesthetic procedures upon graduation. In recent years, a number of efforts have been made to address this concern, including increasing the required residency aesthetic case requirements and the integration of resident aesthetic clinics to increase exposure and independence in this aspect of training. Numerous studies have been conducted to evaluate the efficacy of these resident-run clinics and have substantiated their value as an important educational tool in residency training and validated their safety in patient care. In fact, survey studies have shown that though residents today show a markedly increased confidence in their training when compared with the past, they still feel there is room for improvement in areas such as facial and minimally invasive surgeries, along with procedures that require higher patient volume to refine. In this article, we review the current state of aesthetic surgery training during plastic surgery residency and discuss future directions in the field.

Quantification of Mandibular Morphology in Pierre Robin Sequence to Optimize Mandibular Distraction Osteogenesis

Background:

Mandibular distraction osteogenesis (MDO) is the primary surgical intervention to treat airway obstruction in Pierre Robin sequence (PRS). Current morphologic studies of PRS mandibles do not translate into providing airway management decisions. We compare mandibles of infants with nonsyndromic PRS to controls characterizing morphological variances relevant to distraction. We also examine how morphologic measurements and airway grades correlate with airway management.

Methods:

Patients with PRS under 2 months old were age and sex matched to controls. Demographic and perioperative data, and Cormack-Lehane airway grades were recorded. Computed tomography scans were used to generate mandibular models. Bilateral condylions, gonions, and the menton were identified. Linear and angular measurements were made. Wilcoxon rank sum and 2-sample t tests were performed.

Results:

Twenty-four patients with PRS and 24 controls were included. Seventeen patients with PRS required MDO. PRS patients had shorter ramus heights (16.7 vs 17.3 mm; P = .346) and mandibular body lengths (35.3 vs 39.3 mm; P < .001), more acute gonial angles (125.3° vs 131.3°; P < .001), and more obtuse intergonial angles (94.2° vs 80.4°; P < .001) compared to controls. No significant differences were found among patients requiring MDO versus conservative management nor among distracted patients with high versus low airway grades.

Conclusion:

Our study examines the largest and youngest PRS population to date regarding management of early airway obstruction with MDO. Our findings indicate that univector mandibular body distraction allows for normalization in nonsyndromic patients with PRS, and airway obstruction management decisions should remain clinical.

Fat Grafting for Hand Rejuvenation

The hands are one of the most visible parts of the body, and prominent dorsal veins and extensor tendons are the most readily recognized signs of the aging process. Fat grafting has been demonstrated to be a safe and effective method of hand rejuvenation by restoration of subcutaneous fat. Despite some variability in the technical approach, fat grafting techniques are consistent in their use of low-pressure injection with standard cannula sizes, small aliquots of graft, and a total volume of graft greater than or equal to 15 mL per hand. While distribution of the fat is an area of debate and a topic of active research, published studies have shown high patient satisfaction rates, suggesting that perhaps the restoration of volume alone is paramount. In this article, we will review the applications of fat grafting to the hand, focusing primarily on its role in hand rejuvenation.

Safety and Regulation of Fat Grafting

Today, fat grafting has wide applicability across plastic surgery disciplines, including both aesthetic and reconstructive procedures. However, much controversy has surrounded adipose tissue transfer throughout the 20th century, necessitating extensive research to improve the fat grafting process and to better understand its associated complications and benefits. Initial concerns included the technical difficulties of properly handling and processing adipose to ensure adequate outcomes. As these issues were addressed, more modern concerns were raised by the U.S Food and Drug Administration and the general scientific community regarding the oncological potential of adipose tissue and its potential interference with breast cancer screenings. Today, many formalized clinical studies have evidenced the safety of fat grafting, allowing the procedure to gain widespread popularity and opening avenues for future applications.

Application of Fat Grafting in Cosmetic Breast Surgery

The role of fat grafting to the breasts has evolved in the recent past, gaining several new applications within both reconstructive and aesthetic surgery. Initially used for reconstructive purposes to fill lumpectomy defects or to correct residual contour deformities after breast reconstruction, it has since made its way into cosmetic breast surgery and has grown to encompass a wide variety of new indications. Fat grafting in aesthetic breast surgery may be performed as a form of primary autologous breast augmentation or as an adjunct to implant-based breast augmentation to disguise implant edges. It may also be used to provide added volume after explant surgery or to provide improvements in breast contour alongside mastopexy techniques. In this article, we will review the current applications of fat grafting in aesthetic breast surgery and provide an up-to-date summary of its reported outcomes, safety, and complications.

Applications of Fat Grafting in Pediatric Patients

Autologous fat grafting has become a widely utilized technique for a variety of cosmetic and reconstructive procedures. Its potential for volume restoration and tissue regeneration has made it a popular method for treating soft tissue defects in both adult and pediatric populations. While autologous fat grafting in the pediatric setting is not as well characterized as it is in the adult setting, various reports have demonstrated the safety and utility of its applications in nonadult patient populations. In this article, we present the first comprehensive review of the current applications of autologous fat grafting in pediatric patients. Specific challenges to fat grafting in the pediatric setting and future applications will also be discussed.

Fat Grafting in Breast Reconstruction

The past two decades have witnessed a growing application of autologous fat grafting in the setting of breast reconstruction after surgical treatment of breast cancer. While traditionally used to correct contour deformities during secondary revisions, fat grafting has since evolved to achieve desired breast shape and size both as a complementary adjunct to established reconstructive techniques as well as a standalone technique for whole breast reconstruction. In this article, we will review fat grafting as an adjunct to autologous and implant-breast based reconstruction, an option for primary breast reconstruction, and a treatment of postmastectomy pain.

Fat Grafting for Facial Rejuvenation

For optimal results, facial rejuvenation procedures should address both the tissue laxity and volume deflation associated with facial aging. The lift-and-fill face lift, in which fat grafting provides volumetric rejuvenation to the face while surgical lift effectively repositions and removes ptotic and redundant tissue, has revolutionized the plastic surgeon's approach to the aged face. An understanding of the intricate anatomy of distinct facial fat compartments and a systematic method to assess areas of fat atrophy and volume depletion are keys to provide patients with a natural and youthful result. Fat grafting may be used to improve contour in any area treatable by nonautologous injectable fillers, including the temples, forehead, upper and lower orbit, cheeks, perioral region, nasolabial fold, jawline, and chin-with the benefit of a more natural contour and integration with native tissue.

The Role of Fat Grafting in Buttock Augmentation

Autologous fat grafting is now considered the gold standard for buttock augmentation. Although a variety of techniques are currently being used by surgeons around the world, methods of fat grafting to the buttocks remain unsystematized, poorly understood, and controversial in terms of their safety and efficacy. Nonetheless, buttock augmentation by fat grafting has a satisfaction rate of 97.1%, and its mean complication rate has been estimated to be around 7 to 10%, with serious complications occurring in less than 1% of cases. Fat emboli are one such serious complication, with several reports in the literature discussing morbidity and mortality, specifically with intramuscular injection. With the increasing popularity of fat grafting for buttock augmentation, it is more important than ever to continue researching and learning to safeguard the satisfaction and safety of our patients.

Augmentation Phalloplasty for Acquired Penile Shortening: A Systematic Review of Techniques, Outcomes, Patient Satisfaction, and Limitations

INTRODUCTION

Although an infrequent cause of small penile size in adult men, acquired penile shortening represents a particular reconstructive challenge due to preexisting penile anatomic deformities.

AIM

With numerous techniques being performed, the purpose of our study is to assess available literature on length enhancement procedures used for acquired penile shortening deformities.

METHODS

A systematic review was performed using the guidelines outlined in the Preferred Reporting Items for Systematic reviews and Meta-analyses. Medline/PubMed, Scopus, and Cochrane Databases were used to identify papers on augmentation Phalloplasty in non-transgender males with acquired penile shortening from 1990 to 2018.

MAIN OUTCOME MEASURE

Outcomes, complications, and patient-reported satisfaction were analyzed.

RESULTS

12 articles, involving 931 patients and 8 primary procedures, met our inclusion criteria. The majority of articles had level of evidence of 4 (83%) and Newcastle Ottawa Scale score of 6 (92%, moderate risk of bias). All studies reported mean penile length gain; however, inconsistent methodology was used when measuring penile dimensions. Mean length gain ranged from 0.6 to 6.4 cm. Overall, the mean complication rate for all techniques ranged from 0% to 50%. Post-operative satisfaction was reported in 10 (83%) studies, 7 of which used a validated scale. Patients were generally satisfied, with reported satisfaction rates ranging from 77% to 100%.

CLINICAL IMPLICATIONS

While numerous procedures have been described, the significant limitations in the available data preclude identifying a single superior procedure.

STRENGTHS & LIMITATIONS

The significant heterogeneity in the reported literature is a limitation of this study and highlights the need for standardized reporting. However, this study is the first to analyze augmentation phalloplasty literature in the setting of acquired penile shortening.

CONCLUSION

Augmentation phalloplasty techniques for acquired penile shortening are evolving and are continuously being modified; best-practice guidelines are crucial to achieve safe and satisfactory outcomes in this population.

Diagnosis of Infectious Fluid Collections in Implant-Based Breast Reconstruction: The Role of Ultrasound

OBJECTIVE

Implant-based breast reconstruction after mastectomy remains the most common reconstructive modality worldwide. Infection is a frequent complication that negatively affects the reconstructive outcome and increases health-care costs. The aim of this study is to evaluate the accuracy of ultrasonography in identifying fluid collections in patients with breast implant infection.

METHODS

After receiving institutional review board approval, a retrospective chart review was performed on patients who presented with breast implant infection after breast reconstruction, during the period 2009-2017. To estimate the sensitivity and specificity of ultrasound (US) in detecting fluid collections, only patients with US evaluation and surgery during the same admission were included.

RESULTS

In total, 64 patients with 64 infected implants met the inclusion criteria. Infected devices included 44 (69%) tissue expanders, and 20 (31%) implants, of which 40 (62%) were placed in the subpectoral and 24 (38%) prepectoral positions. Periprosthetic fluid was identified by US preoperatively in 45 (70%) of the patients, and a fluid collection was found in 61 (95%) of the patients during surgery. Sensitivity and specificity of US were 74% and 100%, respectively. Inaccurate US results were more likely in patients with silicone implants than patients with saline expander implants.

CONCLUSION

Caution should be exercised in interpreting negative US findings in patients with silicone implants in the setting of infection. Other imaging modalities should be explored if US results are negative in cases with high clinical suspicion.

Use of New Technologies in Implant-Based Breast Reconstruction

Outcomes after mastectomy and prosthetic-based breast reconstruction have improved immensely since the development of the first tissue expander and breast implant in the 1960s. One major factor contributing to our improved outcomes over the past two decades is the increasing availability and improvement of perfusion assessment technology. Instrumental methods now exist which allow surgeons to assess tissue viability intraoperatively, and provide actionable, objective data that augments clinical assessment. In this article, the authors detail two commercially available, state-of-the-art technologies that surgeons may use to assist in mastectomy flap assessment and facilitate the reconstructive process.

Update in Direct-to-Implant Breast Reconstruction

Implant-based reconstruction (IBR) remains the most commonly utilized breast reconstruction option for post-mastectomy patients. IBR can be approached as either a one-stage reconstruction or a two-stage reconstruction. Facilitated by improvements in surgical technology and advanced techniques, one-stage reconstruction, also known as direct-to-implant (DTI) reconstruction, involves the insertion of an implant at the time of mastectomy. The decision to pursue either a DTI or a two-stage reconstruction is based on several factors, including the patient's overall health, expected risk of postoperative complications, and associated costs to both the patient and hospital.

Implant Reconstruction in Nipple Sparing Mastectomy

Nipple sparing mastectomy has been popularized in the modern era of breast cancer treatment due to its touted advantages with regard to resultant body image and reconstructive outcome. Implant-based techniques remain the most prevalent means of breast reconstruction. Special considerations regarding patient selection and technique are reviewed for implant reconstruction in the setting of mastectomy with nipple preservation. Applications for prepectoral and direct-to-implant reconstruction are discussed and published outcomes are summarized.
