Nerve Capping Techniques for Neuroma Management: A Comprehensive Literature Review.

BACKGROUND/AIM OF THE STUDY: Nerve capping is a method of neuroma treatment or prevention that consists of the transplantation of a proximal nerve stump into an autograft or other material cap, after surgical removal of the neuroma or transection of the nerve. The aim was to reduce neuroma formation and symptoms by preventing neuronal adhesions and scar tissue. In this narrative literature review, we summarize the studies that have investigated the effectiveness of nerve capping for neuroma management to provide clarity and update the clinician's knowledge on the topic. METHODS: A systematic electronic search following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria was performed in the PubMed database combining "neuroma," "nerve," "capping," "conduit," "treatment," "management," "wrap," "tube," and "surgery" as search terms. English-language clinical studies on humans and animals that described nerve capping as a treatment/prevention technique for neuromas were then selected based on a full-text article review. The data from the included studies were compiled based on the technique and material used for nerve capping, and technique and outcomes were reviewed. RESULTS: We found 10 applicable human studies from our literature search. Several capping materials were described: epineurium, nerve, muscle, collagen nerve conduit, Neurocap (synthetic copolymer of lactide and caprolactone, which is biocompatible and resorbable), silicone rubber, and collagen. Overall, 146 patients were treated in the clinical studies. After surgery, many patients were completely pain-free or had considerable improvement in pain scores, whereas some patients did not have improvement or were not satisfied after the procedure. Nerve capping was used in 18 preclinical animal studies, using a variety of capping materials including autologous tissues, silicone, and synthetic nanofibers. Preclinical studies demonstrated successful reduction in rates of neuroma formation. CONCLUSIONS: Nerve capping has undergone major advancements since its beginnings and is now a useful option for the treatment or prevention of neuromas. As knowledge of peripheral nerve injuries and neuroma prevention grows, the criterion standard neuroprotective material for enhancement of nerve regeneration can be identified and applied to produce reliable surgical outcomes.

The Use of Botulinum Toxin in Raynaud Phenomenon: A Comprehensive Literature Review.

BACKGROUND: Raynaud phenomenon (RP) is a vasospastic condition of the digits that can be primary or secondary to systemic disease. Symptoms are triggered by cold or stress and can cause pain and skin color changes. The chronic ischemia may lead to necrosis, ulceration, and amputation. There are no Food and Drug Administration-approved treatments and cases refractory to pharmacologic and surgical treatments are difficult to control. Local botulinum toxin injections have been increasingly used in the treatment of Raynaud disease and have shown promising results. AIM OF THE STUDY: To examine the outcomes, techniques, and complications of botulinum toxin use for the treatment of Raynaud disease. METHODS: The PubMed database was queried using "botulinum toxin" AND "Raynaud phenomenon" as title key words. Preferred reporting items for systematic reviews and meta-analysis criteria were used. Additional articles were selected while reviewing the references of the articles from PubMed. No time restrictions were followed. Articles of all languages were included. Articles were analyzed for study type, demographics, diagnosis/inclusion criteria, treatment methods, outcome measures, length of follow-up, results, and complications. A positive outcome was defined as subjective improvement in symptoms and/or improvement in the outcome measures. A poor outcome was defined as harm done to the patient by the injection that would not have occurred otherwise. RESULTS: Forty-two clinical studies describing the use of botulinum toxin for Raynaud's phenomenon were found. A total of 425 patients with primary or secondary Raynaud's were treated, with ages ranging from 14 to 91 years. There were 342 women and 81 men, with a female-to-male ratio of 38:9. Outcomes were positive in 96.2% of patients. There were 14.2% of the studies that reported 3.5% of all patients showing no subjective improvement. A single study reported a poor outcome for 1 patient. There were 40.5% of the studies that reported complications, affecting 20.2% of all patients. The most frequently reported complication was transient hand weakness, affecting 44.2% of patients with complications and 8.9% of total patients. Weakness resolved in hours to months after injection. Pain at the injection site lasting minutes to days was reported in 40.7% of patients with complications, and 8.2% of total patients. CONCLUSIONS: Botulinum toxin treatment for RP is effective. Complications are minor and self-limiting.

Anthropometric Cranial Measurements in Metopic Craniosynostosis/Trigonocephaly: Diagnostic Criteria, Classification of Severity and Indications for Surgery.

ABSTRACT: Metopic craniosynostosis is the second most frequent type of craniosynostosis. When the phenotypic presentation has been deemed severe the treatment is surgical in nature and is performed in infancy with fronto-orbital advancement and cranial vault remodeling. At the time of this writing, there is no consensus regarding an objective evaluation system for severity, diagnostic criteria, or indications for surgery. This study aims to review the anthropometric cranial measurements and the relative diagnostic criteria/classification of severity/surgical indications proposed so far for this skull malformation, and to investigate if there is any scientific support for their utility.

Recurrence of breast ptosis after mastopexy - a prospective pilot study.

BACKGROUND: Breast ptosis is characterized by severe volumetric deficiency of the upper pole, excess of skin in the lower pole and descent of the nipple-areola complex (NAC). Mastopexy, also known as breast lifting, is the surgical operation aimed to reshape the ptotic breast. Recurrence of breast ptosis after mastopexy is common but to the best of our knowledge no study before has measured it. PURPOSE: The aim of this study was to measure the recurrence of breast ptosis after mastopexy in a prospective study. MATERIALS AND METHODS: Female patients affected by unilateral or bilateral moderate or severe breast ptosis were enrolled in the study. All the patients underwent mastopexy performed only with the removal of skin excess following a Wise pattern. The jugular notch-nipple distance was measured before surgery, immediately after surgery and after 1, 3, 6 and 12 months. RESULTS: Ten patients were included in the study, four underwent unilateral mastopexy and six underwent bilateral mastopexy. The lifting of the NAC, measured in the immediate post-operative period, ranged from 3 to 8.5 cm, with an average value of 6.3 cm. This lifting, one year after surgery, ranged from 2 to 7 cm, with an average value of 4.6 cm. The percentage loss of the NAC lifting one year after surgery compared to the immediate post-operative time ranged from 12.5 to 41.7%, with an average value of 27.5%. CONCLUSION: In our case series, the lifting of the NAC obtained immediately after surgery showed an average loss of 27.5% one year after surgery. Even if limited by the low number of patients included, this pilot study is eye-opening on a very common phenomenon that occurs after mastopexy. The patients should be informed about the possible recurrence of the breast ptosis.

Pre-Pectoral One-Stage Breast Reconstruction with Anterior Coverage Using Superior Anterior Biological Acellular Dermal Matrix (ADM) and Inferior Anterior Dermal Sling Support.

The use of acellular dermal matrix (ADM) implants has enhanced breast reconstruction. ADM is a biotechnologically designed human tissue of bovine or porcine origin in which tissue processing removes cellular antigens. In this case report, we describe the use of ADM in one-stage prepectoral breast reconstruction. Skin-reduction breast reconstruction with a prepectoral implant was performed. We created a combined dermal pocket using the inferior dermal flap, sutured with a patch of acellular dermal matrix to continue its extension until the upper pole, to cover the implant. This technique offers single-stage immediate reconstruction, with a decreased requirement for ADM and increased use of vascularized tissue and implant support. Additionally, in the pre-pectoral space, decreased pain postoperatively and less anatomic disruption is offered.

What is Beauty?

PURPOSE: In the current study, the authors attempt to thoroughly investigate the concept of beauty from different perspectives in different historical periods and offer their personal thoughts about it. METHODS: The authors performed a comprehensive and across-the-board literature review about 'beauty', including beauty from a philosophical perspective, beauty perception by human mind, beauty from a biopsychological perspective, beauty of the face, body and breast, models of beauty and beauty in cosmetic surgery. RESULTS: From Plato to modern neuro-psychological studies, the concept of beauty has always been a theme for adamant debates and passionate thoughts. Different aspects of beauty, from intellectual to pure physical, have received a tremendous amount of attention. The true definition of the concept of beauty is still ambiguous, and there is not a unanimous explanation for it. It seems that the definition of beauty differs in every individual's mind and over the history of humankind. CONCLUSION: Although beauty is a very important concept and the seek for achieving it is a very natural behavior, one must remember that the importance of beauty should not overshadow the fact that every human being is made up of similar internal organs. We strongly encourage the reader to look beyond the hedge, to be aware that each of us is made up of internal organs, beyond the external appearance.

Umbilical Reconstruction Techniques: A Literature Review.

BACKGROUND: There are many instances in which sacrificing the umbilicus is unavoidable. Umbilical reconstruction (umbiliconeoplasty) is an important surgical procedure to complete the abdomen's reconstruction and to give again a pleasant cosmetic appearance. OBJECTIVES: To provide a complete overview of all surgical techniques for umbiliconeoplasty described in the literature. METHODS: PubMed database was queried using 'umbilical and reconstruction', 'umbilicus and reconstruction', 'navel and reconstruction', 'umbiliconeoplasty', 'neo-omphaloplasty' or 'umbilicaneoplasty' to select the papers dealing with the reconstruction of the umbilicus. RESULTS: Sixty different techniques for the reconstruction of the missing umbilicus were described in 77 papers. Local skin flaps and the purse-string suture technique were the most frequently described techniques. The Three flaps technique, the Four flaps technique and the 2 Lateral rectangular pedicle lateral flaps technique were the most popular local flap techniques. Indications ranged from congenital pediatric defects to reconstruction during abdominoplasty. CONCLUSIONS: Several surgical techniques were described for umbilicus reconstruction. While there is not a universal algorithm for the choice of the technique, the surgeon may decide which technique to use based on other surgeons' experiences reports.

Artificial Intelligent Virtual Assistant for Plastic Surgery Patient's Frequently Asked Questions: A Pilot Study.

BACKGROUND: Artificial Intelligent Virtual Assistants (AIVA) is a segment of artificial intelligence that is rapidly developing. However, its utilization to address patients' frequently asked questions remains unexplored. METHODS: We developed an AIVA to answer questions related to 10 frequent topics asked by plastic surgery patients in our institution. Between July 27, 2018, and August 10 of 2018, we recruited subjects with administrative positions at our health care institution to chat with the virtual assistant. They asked, with their own words, 1 question for each topic and filled out a satisfaction questionnaire. Postsurvey analysis of questions and answers allowed assessment of the virtual assistant's accuracy. RESULTS: Thirty participants completed the survey. The majority was female (70%), and the mean age was 27.76 years (SD, 8.68 [19-51] years). The overall accuracy of the plastic surgery AIVA was 92.3% (277/294 questions), and participants considered the answer correct in 83.3% of the time (250/294 answers). Most of the participants considered the AIVA easy to use, answered adequately, and could be helpful for patients. However, when asked if this technology could replace a human assistant, they stayed neutral.

The Multifactorial Contribution of Publications in Plastic Surgery Journals in Microsurgery Education.

BACKGROUND: Microsurgery is one of the most complex operative skills. Recent restrictions on residents' working hours challenge residency program directors to ensure skill acquisition with scant time dedicated to microsurgery practice. We aimed to summarize the contribution of plastic surgery journals in microsurgical education. METHODS: A comprehensive literature search was performed. RESULTS: We observed an increasing number of publications on microsurgery education over the years. This could be due to the adoption of new technologies developed in the last 2 decades, the concerns about quality of resident training in the context of reduced work hours, the well-described benefit of medical simulations in other specialties, and the pressure on trainees to be proficient before operating on patients. The variety of aspects addressed in plastic surgery publications is broad: simulators, courses, skills assessment, national surveys, and technology trends. CONCLUSION: There is an upward trend in the number of publications and plastic surgery journals, demonstrating a remarkable contribution to microsurgery training.

Alveolar Rhabdomyosarcoma Following Mandibular Distraction Osteogenesis.

The authors present a rare case of anaplastic alveolar rhabdomyosarcoma (ARMS) occurring after Mandibular Distraction Osteogenesis. A 16-month-old male presented with a rapidly enlarging left lower jaw mass after removal of mandibular distractors placed shortly after birth for Pierre Robin Sequence and severe obstructive sleep apnea. Incisional biopsy of the mass revealed ARMS with anaplastic features. Although ARMS is an extremely rare entity, craniofacial surgeons should have a low threshold for seeking further diagnostic modalities of a growing mass postmandibular distraction.

Nipple-Areola Complex Reconstruction.

Disparities in Access to Autologous Breast Reconstruction.

Background and objectives: This study aimed to determine if age, race, region, insurance, and comorbidities affect the type of breast reconstruction that patients receive. Materials and methods: This analysis used the Florida Inpatient Discharge Dataset from 1 January 2013 to 30 September 2017, which contains deidentified patient-level administrative data from all acute care hospitals in the state of Florida. We included female patients, diagnosed with breast cancer, who underwent mastectomy and a subsequent breast reconstruction. We performed an χ2 test and logistic regression in this analysis. Results: On the multivariable analysis, we found that age, race, patient region, insurance payer, and Elixhauser score were all variables that significantly affected the type of reconstruction that patients received. Our results show that African American (odds ratio (OR): 0.68, 95%CI: 0.58-0.78, p < 0.001) and Hispanic or Latino (OR: 0.82, 95%CI: 0.72-0.93, p = 0.003) patients have significantly lower odds of receiving implant reconstruction when compared to white patients. Patients with Medicare (OR: 1.57, 95%CI: 1.33-1.86, p < 0.001) had significantly higher odds and patients with Medicaid (OR: 0.61, 95%CI: 0.51-0.74, p < 0.001) had significantly lower odds of getting autologous reconstruction when compared to patients with commercial insurance. Conclusions: Our study demonstrated that, in the state of Florida over the past years, variables, such as race, region, insurance, and comorbidities, play an important role in choosing the reconstruction modality. More efforts are needed to eradicate disparities and give all patients, despite their race, insurance payer, or region, equal access to health care.

Chronic Tenosynovitis of the Upper Extremities Caused by Mycobacterium kansasii : A Clinical Case and Systematic Review of Literature.

Background Chronic tenosynovitis of the upper extremities caused by Mycobacterium kansasii ( M. kansasii ) is uncommon, but symptoms may overlap with other more common diseases. Late diagnosis and treatment can lead to disfiguration of structures and rupture of tendons, resulting in worse cosmetic outcomes after reconstruction. Methods We present a clinical case and literature review of M. kansasii in patients with chronic tenosynovitis of upper extremities. PubMed was queried for cases of upper extremities tenosynovitis caused by M. kansasii . The keywords " M. kansasii ," "tenosynovitis" and synonyms were used for search in different combinations. Manuscripts, with no specific data or another condition, where the infection was not located in the upper extremities, were reviews, or not in English, were excluded from the study. Results We described 23 reported cases of tenosynovitis of the upper extremity caused by M. kansasii . An immunosuppressed state was present in eight (34.8%) cases, and 12 (52.2%) patients received immunosuppressive treatment. A long-time period between the first appearance of symptoms and the definitive diagnosis was identified (median: 7 months, interquartile range: 9). The most frequent symptoms were local swelling (65.2%), pain (56.5%), mass effect (26%), and stiffness (13%). Tendon rupture was found in three (13%) patients as a complication of the disease. Moreover, seven (30.4%) patients underwent previous surgeries to try to relieve the symptoms before definitive diagnosis was achieved. Conclusion M. kansasii is an important differential causal pathogen for tenosynovitis of the upper extremities. Although rare, raising awareness about this infectious disease is imperative to avoid inadequate management and hazardous aesthetic sequelae.

Primary Hand Leiomyoma: A Systematic Review.

BACKGROUND: Primary leiomyoma is a rare cause of a mass in the hand, with few reported cases to date. To our knowledge, this constitutes the most comprehensive and up-to-date systematic review of the literature of all cases of primary hand leiomyoma. We also provide an additional case recently managed in our practice of confirmed primary vascular leiomyoma of the hand in a 44-year-old woman to add to the current body of literature. METHODS: We performed a comprehensive literature review of all articles published on primary leiomyoma of the hand. The PubMed database was used, with search terms leiomyoma hand, angioleiomyoma hand, and angiomyoma hand. Articles were selected for their accuracy in anatomic localization in the hand and confirmed pathology of leiomyoma. RESULTS: Our initial search query resulted in 216 articles. After applying the inclusion criteria, we identified 50 individual articles with 108 cases of confirmed primary leiomyoma in the hand from January 1, 1954, to July 1, 2018. Common initial clinical impressions recorded for primary hand leiomyoma included ganglion cyst, giant-cell tumor, hemangioma, and glomus tumor. Patients presenting with leiomyoma of the hand frequently describe a painful lesion, which differs from most other benign tumors of the hand at presentation. CONCLUSIONS: Leiomyoma is an important consideration when developing a differential diagnosis for primary benign masses in the hand. We hope that this comprehensive review can provide increased awareness of this tumor type.

National Analysis of Patients With External Ear Melanoma in the United States.

BACKGROUND: External ear melanoma (EEM) is a rare condition with controversies in the literature. We analyzed patients with EEM in the United States compared to other head and neck melanomas (OHNMs). METHODS: The National Cancer Database (NCDB) was used to select patients with head and neck melanoma from January 1, 2004 to December 31, 2015. Mann-Whitney and χ tests were used to estimate statistical significance, and multivariate logistic regression to identify independent associations adjusted for confounders. RESULTS: A total of 137,233 patients met the study criteria. Among them, 16,991 (12.4%) had EEM and 120,242 (87.6%) had OHNM. For patients with EEM, the mean (standard deviation) age was 66.26 (15.798) years. Most of the patients with EEM were men (85.5%), insured by Medicare (52.4%), and treated in Academic/Research Programs (47.7%) or Comprehensive Community Cancer Programs (32.3%). Most of the EEM tumors had invasive behavior (68.0%) were Stages 0 (30.3%) or I (40.3%), and were without ulceration (76.9%). Mean time to receive any treatment was 14.1 days for EEM compared with 14.6 days for OHNM (P < 0.001). We noticed a greater proportion of EEM in men (14.8%; adjusted odds ratio [aOR] 2.72 [2.605-2.852]; P < 0.001) compared to women (6.22%; reference). EEM was an independent factor for tumor Stage I (14.47%; aOR 1.61 [1.101-1.224], P < 0.001) and invasive behavior (13.86%; aOR 1.268 [1.15-1.389]; P < 0.001) compared to OHNM. CONCLUSION: EEM was associated with higher odds of invasive behavior compared to OHNM. Furthermore, men were found to have a higher likelihood to develop EEM compared to women.

Eyelid Melanoma in the United States: A National Cancer Database Analysis.

BACKGROUND: Eyelid melanoma (EM) is a rare condition that accounts for <1% of all cutaneous melanomas. In this analysis, patients diagnosed with EM in the United States were compared to those with other melanomas in the head and neck. METHODS: The National Cancer Database was used to select patients with head and neck melanoma from 2004 to 2015. RESULTS: A total of 137,233 patients met the criteria of the study. Among them, 2694 were diagnosed with EM (2%) and 134,539 in other head and neck locations (98%). Regarding the patients with EM, the mean age was 68.56 years (standard deviation 14.04). A greater number of them were treated in Academic/Research Programs (53.6%), insured by Medicare (55.7%), tumor in situ (52.2%), stage 0 (49%), and without ulceration (75.9%). The mean time to treatment commencement was 18.96 days for EM compared to 14.4 days for other melanoma in the head and neck regions (P < 0.001). There was a greater proportion of EM in female patients (odds ratio [OR] 2.371 [2.191-2.566], P < 0.001), compared to male; age greater than 80 years (OR 1.622 [1.360-1.934], P < 0.001) compared to 0 to 49 years. Moreover, EM was an independent predictor for treatment in Academic/Research Programs (OR 1.258 [1.160-1.365], P < 0.001) and diagnosis at autopsy (OR 1.414 [1.083-1.847], P = 0.011) compared to other melanoma in the head and neck region. CONCLUSION: These novel findings have the potential to guide clinical decision making in head and neck melanoma management.

Alloplastic Facial Implants: A Systematic Review and Meta-Analysis on Outcomes and Uses in Aesthetic and Reconstructive Plastic Surgery.

BACKGROUND: Alloplastic materials in facial surgery have been used successfully for various applications in the reconstructive restoration or aesthetic augmentation of the facial skeleton. The objective of this study was to conduct a comprehensive systematic review of alloplastic implant materials utilized to augment the facial skeleton stratified by anatomical distribution, indication, specific material used, and respective outcomes. METHODS: A comprehensive systematic review on alloplastic facial implant data was conducted utilizing Medline/PubMed database. Articles were stratified by (1) anatomic localization in the face, as well as (2) alloplastic material. RESULTS: A total of 17 studies (n = 2100 patients, follow-up range = 1 month-27 years) were included. Overall, mersilene mesh implants were associated with the highest risk of infection (3.38%). Methyl methacrylate implants were associated with the highest rate of hematoma (5.98%). Implants placed in the malar region (2.67%) and frontal bones (2.50%) were associated with the highest rates of infection. Implants placed in the periorbital region were associated with the highest rate of inflammation (8.0%), explantation (8.0%), and poor cosmetic outcome (17.0%). Porous implants were shown to be more likely to potentiate infection than non-porous implant types. CONCLUSIONS: Alloplastic facial implants are a reliable means of restoring facial symmetry and achieving facial skeletal augmentation with a relatively low complication profile. It is important for plastic surgeons to understand the relative risks for each type of implant to develop postoperative complications or poor long-term cosmetic results. Interestingly, porous implants were shown to be more likely to potentiate infection than non-porous implant types.

Postmastectomy Radiation Therapy (PMRT) before and after 2-Stage Expander-Implant Breast Reconstruction: A Systematic Review.

Background: In those undergoing treatment for breast cancer, evidence has demonstrated a significant improvement in survival, and a reduction in the risk of local recurrence in patients who undergo postmastectomy radiation therapy (PMRT). There is uncertainty about the optimal timing of PMRT, whether it should be before or after tissue expander or permanent implant placement. This study aimed to summarize the data reported in the literature on the effect of the timing of PMRT, both preceding and following 2-stage expander-implant breast reconstruction (IBR), and to statistically analyze the impact of timing on infection rates and the need for explantation. Methods: A comprehensive systematic review of the literature was conducted using the PubMed/Medline, Ovid, and Cochrane databases without timeframe limitations. Articles included in the analysis were those reporting outcomes data of PMRT in IBR published from 2009 to 2017. Chi-square statistical analysis was performed to compare infection and explantation rates between the two subgroups at p < 0.05. Results: A total of 11 studies met the inclusion criteria for this study. These studies reported outcomes data for 1565 total 2-stage expander-IBR procedures, where PMRT was used (1145 before, and 420 after, implant placement). There was a statistically significant higher likelihood of infection following pre-implant placement PMRT (21.03%, p = 0.000079), compared to PMRT after implant placement (9.69%). There was no difference in the rate of explantation between pre-implant placement PMRT (12.93%) and postimplant placement PMRT (11.43%). Conclusion: This study suggests that patients receiving PMRT before implant placement in 2-stage expander-implant based reconstruction may have a higher risk of developing an infection.

Local Pro- and Anti-Coagulation Therapy in the Plastic Surgical Patient: A Literature Review of the Evidence and Clinical Applications.

The risks of systemic anti-coagulation or its reversal are well known but accepted as necessary under certain circumstances. However, particularly in the plastic surgical patient, systemic alteration to hemostasis is often unnecessary when local therapy could provide the needed adjustments. The aim of this review was to provide a summarized overview of the clinical applications of topical anti- and pro-coagulant therapy in plastic and reconstructive surgery. While not a robust field as of yet, local tranexamic acid (TXA) has shown promise in achieving hemostasis under various circumstances, hemostats are widely used to halt bleeding, and local anticoagulants such as heparin can improve flap survival. The main challenge to the advancement of local therapy is drug delivery. However, with increasingly promising innovations underway, the field will hopefully expand to the betterment of patient care.
