Plastic Surgery and the COVID-19 Pandemic: A Review of Clinical Guidelines.

BACKGROUND: A novel coronavirus disease (COVID-19) was first reported in December 2019 in China and was soon declared a pandemic by the World Health Organization. Many elective and nonessential surgeries were postponed worldwide in an effort to minimize spread of disease, as well as to conserve resources. Our goal with this article is to review current practice guidelines in setting of the COVID-19 pandemic, based on available data and literature. METHODS: Websites pertaining to surgical and medical societies, and government agencies were reviewed, along with recently published literature to identify recommendations related to COVID-19 and plastic surgery procedures. RESULTS: Clinical practice modifications are recommended during the pandemic in outpatient and perioperative settings. Use of personal protective equipment is critical for aerosol-generating procedures, such as surgery in the head and neck area. Care for trauma and malignancy should continue during the pandemic; however, definitive reconstruction could be delayed for select cases. Specific recommendations were made for surgical treatment of cancer, trauma, and semiurgent reconstructive procedures based on available data and literature. CONCLUSIONS: The risk and benefit of each reconstructive procedure should be carefully analyzed in relation to necessary patient care, minimized COVID-19 spread, protection of health care personnel, and utilization of resources. Recommendations in this article should be taken in the context of each institute's resources and prevalance of COVID-19 in the region. It should be emphasized that the guidelines provided are a snapshot of current practices and are subject to change as the pandemic continues to evolve.

Clinical Anatomy of Submental Intubation: A Review of the Indications, Technique, and a Modified Approach.

Since its original description in 1986 by Hernandez, submental intubation has been used in a wide variety of craniomaxillofacial cases as a way to satisfy both surgeon and anesthesiologist to provide access to necessary surgical sites and airway protection. Many modifications to the original technique have been described. There has been a paucity of plastic surgery literature over the last 10 years that have reviewed the anatomy, technique, and complications. In this article, the authors review the pertinent anatomy related to this method of intubation. A cadaver was used to enhance visualization of important structures and to show the modification used by our group. Submental intubation provides a useful alternative to tracheostomy in several craniomaxillofacial procedures. Our approach uses a reinforced endotracheal tube to prevent kinking and provide additional intraoperative protection of the airway. Submental intubation may be indicated in select patients undergoing craniomaxillofacial surgery. Therefore, it is pertinent to be aware of the important anatomy and the complications of this technique to appropriately counsel patients. Our modification provides safe airway control.

Revisiting the "July Effect" in Plastic Surgery: New Data to Support Resident Autonomy.

BACKGROUND: The "July Effect" represents a topic of considerable interest across residency programs. This study investigated the frequency of postoperative complications following procedures with plastic surgery resident participation (all postgraduate year [PGY] levels) during the first (quarter 3, July-September) and last academic quarters. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was used to calculate complication rates from 2006 to 2010. Resident involvement was analyzed as a categorical variable consisting of "juniors" (PGY1-PGY3), and "seniors" (PGY4-PGY6). Outcomes from procedures during Q3 were compared with all quarters. Propensity score matching and adjustment enabled logistic regression identifying the effect of resident involvement and admission. RESULTS: Among all cosmetic and reconstructive procedures (n = 6625), mean operative time was not significantly greater in Q3 compared with all other quarters (P = 0.069); no significant differences in complication rates were observed between Q3 and all other quarters, though superficial surgical site infection (SSI) approached significance (3.3% of procedures in Q3 vs 2.5% in all other quarters, P = 0.063). Among reconstructive procedures only (n = 5677), mean operative time was not significantly greater in Q3 compared with all other quarters (P = 0.119); the same held true for cosmetic procedures only (P = 0.275). Surgical site infection, however, was significantly more likely to occur with reconstructive procedures only, in Q3 compared with all other quarters (3.5% of cases vs 2.3%, P = 0.024). When adjusting for PGY status and matching populations, superficial SSI and return to the operating room were not significantly more common in Q3. When adjusting for quarter of admission, however, superficial SSI was significantly more common among the overall and noncosmetic cases with participation by junior residents (P = 0.013 and 0.020, respectively). CONCLUSIONS: This may represent the first fully reproducible, transparent National Surgical Quality Improvement Program study in plastic surgery that demonstrates the absence of a clinically significant "July Effect," and suggests that an appropriate degree of resident autonomy may pose minimal risk during both cosmetic and reconstructive procedures in residency training. Additionally, the findings encourage the development a plastic surgery-specific database to remedy inherent difficulties with larger, more comprehensive surgical databases.

Microsurgical reconstruction of complex maxillofacial gunshot wounds: Outcomes analysis and algorithm.

BACKGROUND: Satisfaction with appearance, functional outcomes (speech, swallowing), work status after microsurgical reconstruction for maxillofacial gunshot wounds (GSW) remain largely unknown. The purpose of this study is to report these parameters. By investigating these outcomes, we also aimed to provide microsurgical algorithms for complex maxillofacial GSW. METHODS: Forty-two consecutive maxillofacial GSW patients between 2006 and 2014 were analyzed for outcomes. Mean age was 41.3 years ranging 14 to 77 years. There were 33 males and 9 females. RESULTS: Twenty-four patients received 36 free flaps for early reconstruction in 1 to 2 weeks, two patients in a delayed manner. Fifteen fibula flaps for mandible reconstruction, five fibula, there radial forearm (RF), and two scapular osteocutaneous (OC) flaps for maxilla reconstruction, two RF flaps for palate reconstruction, one RF for cheek reconstruction were used. Four patients underwent innervated gracilis flap for total lower lip and one for cheek reconstruction. Rectus abdominis myocutaneous flap was used for mid-face defects in two patients. One anterolateral thigh flap was used for lower lip/chin reconstruction. Nine free flaps were performed to treat a complication and/or to improve function. All flaps survived except for three partial skin paddle loss to fibula flaps. Mean follow-up was 17.2 months. Return to work/school was 70%. Surveys noted 58% "satisfied". All patients but two achieved perceptible speech, the majority had no difficulty with swallowing, all patients had oral competence. CONCLUSIONS: Favorable outcomes were obtained in most maxillofacial GSW. After investigating these outcomes, microsurgical algorithms were developed for clinical practice for reconstruction of composite mandible and total-lower lip defects, and maxilla/mid-face defects.

A medieval physician: Amirdovlat Amasiatsi (1420-1495).

We aimed to acquaint the reader with a medieval physician, Amirdovlat Amasiatsi, who lived and practiced in the 15th century Anatolia. Amirdovlat wrote several books on medicine mainly focusing on phytotherapy and pharmacology using medicinal plants, animal-derived products and minerals. All his works were written in Middle Armenian, spoken Armenian language of the time. In his writings, Amirdovlat described unique recipes that represent a portrayal of medical knowledge and practice at the time in Anatolia where he lived and worked. He discussed the physical and therapeutic properties as well as geographic distributions of various plants and minerals, using different languages, mainly Turkish, Greek, Arabic, French and Persian. Amirdovlat's works not only enhanced our understanding of Armenian medical practices but also provided great deal of information on those of Ancient Greco-Roman as well as Islamic world, demonstrating close relationship of Armenian medicine with Greco-Roman and Islamic medicine. Amirdovlat accomplished this by amalgamating the past and contemporary practices of his time. In this regard, Amirdovlat's works, in particular "Useless for the Ignorant", are very unique playing a significant role in preserving traditions and heritage of different cultures.

Donor skin allograft survival after bone marrow transplantation: Case report and systematic review of the literature☆.

BACKGROUND: We present a case of skin allograft survival in a patient who previously received a bone marrow transplant from the same HLA-matched donor. DNA fingerprinting of skin biopsies showed mixed cellularity originating from the donor and recipient (68% and 32% donor DNA in the allograft skin and the native recipient's skin, respectively). Histologic sections demonstrated both grade 3/4 rejection and graft-versus-host-disease. We have conducted a systematic review in search for other cases of donor skin allograft survival after a bone marrow or hematopoietic stem cell transplantation. METHODS: All reported cases in English, Spanish, French, and German were captured using the electronic databases. Bibliographies of relevant articles were manually searched. RESULTS: Nineteen patients (12 females) who received skin allografts from their bone marrow or hematopoietic stem cell donors were identified. Average age was 27.2 years (range: 5 months to 64 years). Skin allografts were used to treat graft-versus-host-disease, Herlitz junctional epidermolysis bullosa, and to test tolerance before a kidney transplantation from the same donor. Eight cases were not receiving immunosuppressive therapy. Allografts survived in all patients. In three patients, skin punch biopsies were taken, and these biopsies demonstrated mixed donor and recipient cellularity. The pathology result is specified in two more cases, with no signs of rejection. CONCLUSIONS: The same donor skin allografts may be a safe option to treat severe cutaneous conditions in recipients of a bone marrow/hematopoietic stem cell transplantation. However, future studies are needed to confirm these results.

A literature review and meta-analysis of outcomes in microsurgical reconstruction using vasopressors.

INTRODUCTION: There is a hesitancy to utilize vasopressors in microsurgical reconstruction due to fear of vessel spasm and subsequent flap compromise. Although there are large literature reviews analyzing vasopressor usage in head and neck reconstruction, this has not been extrapolated to all regions of the body. The goal of this study was to perform a meta-analysis examining vasopressor usage and risk of complications in microsurgical reconstruction for all recipient sites. MATERIALS AND METHODS: A meta-analysis was conducted for articles discussing the utilization of vasopressors in microsurgical reconstruction. The primary endpoint was total flap failure. Secondary endpoints were necessity for operative take-back and hematoma requiring intervention. Odds ratios were calculated for each complication and for each study. RESULTS: Four prospective and six retrospective studies were analyzed yielding 6321 patients and 7526 flaps. 67.4% (966/1433) of patients received vasopressors and 80.8% (6080/7526) of flaps received vasopressors. There were 100 failures in the vasopressor group (100/6080 = 15.9%) and 39 failures in the non-vasopressor group (39/1456 = 26.8%) (O.R. 0.73; p = 0.12). There were 177 take-backs in the vasopressor group (177/5916 = 29.9%) and 64 take-backs in the non-vasopressor group (64/1404 = 4.6%) (O.R. 0.65; p < 0.05). There were 73 hematomas in the vasopressor group (73/5099 = 14/3%) and 14 hematomas in the non-vasopressor group (14/979 = 14.3%) (O.R. 1; p = 0.89). The odds ratio for total flaps failures in the breast and head/neck cohorts were 0.788 (p = 0.76) and 1.2761 (p = 0.77), respectively, with neither significantly increased in flaps receiving vasopressors. CONCLUSION: Our results suggest that vasopressor utilization does not directly result in increased complications. Flaps that received vasopressors had a statistically lower rate of take-back and failure. Due to the paucity of data available for analysis and limited reporting relating flap characteristics to outcomes, prospective, well-designed studies are necessary to verify the safety of vasopressor use in microsurgical reconstruction.

Prospective, Randomized, Controlled Comparison of Bupivacaine versus Liposomal Bupivacaine for Pain Management after Unilateral Delayed Deep Inferior Epigastric Perforator Free Flap Reconstruction.

Effective postsurgical analgesia is a critical aspect of patient recovery. The goal of this prospective, randomized, controlled, blinded study was to examine the effect that liposomal bupivacaine delivered by means of a transversus abdominis plane block has on pain control in women undergoing unilateral deep inferior epigastric perforator flap reconstruction. Institutional review board approval was granted for this prospective study. Patients were eligible if they were undergoing unilateral, delayed deep inferior epigastric perforator flap reconstruction. Patients were randomized to one of three groups: liposomal bupivacaine transversus abdominis plane block, or bupivacaine pain pump. Charts were reviewed for demographics, length of stay, and postoperative narcotic use. There were eight patients in the liposomal bupivacaine and bupivacaine transversus abdominis plane block groups and five patients in the pain pump group. A retrospective cohort of six patients who did not receive any intervention was included. Patients who received a liposomal bupivacaine transversus abdominis plane block used statistically significantly less intravenous and total postoperative narcotics in milligrams and milligrams per kilogram per day compared with all other cohorts. They were able to get out of bed at an earlier time point. Overall hospital costs were similar among the groups. This is the first study to investigate liposomal bupivacaine delivered as a transversus abdominis plane block in a prospective, randomized, blinded study in women undergoing unilateral, delayed, abdominally based autologous breast reconstruction. The authors were able to demonstrate a significant reduction in intravenous and total narcotic use when a liposomal bupivacaine transversus abdominis plane block was used. Future studies are needed to prospectively investigate the effect that liposomal bupivacaine would have on immediate and bilateral reconstructions.

Single-stage versus two-stage arteriovenous loop microsurgical reconstruction: A meta-analysis of the literature.

BACKGROUND: Arteriovenous (AV) loops can be utilized in a single- or two-stage approach in free flap reconstruction when proper vessels are not available. However, there exists no consensus on which method leads to superior microsurgical and patient outcomes. The purpose of this article was to review single- versus two-stage AV loops utilized in free flap reconstruction with a focus on complications and overall outcomes. METHODS: A systematic review of AV loops for autologous free tissue transfer was conducted. Endpoints investigated included flap characteristics, timing to second stage, complications, and outcomes. A Student's t-test and forest plots were used for statistical analysis. RESULTS: Thirty-five unique papers discussed utilizing AV loops in a single- or two-stage approach, yielding 260 and 98 single- and two-stage AV loops, respectively. There was a statistically significant higher rate of major complications in two-stage as compared to single-stage AV loops. There was a non-statistically significant difference in rate of minor complications in the single-stage as compared to two-stage AV loops. Overall, there was a statistically significant higher success rate in the single-stage as compared to two-stage AV loops CONCLUSION: There was a statistically significant higher rate of major complications and failures in two-stage AV loops. As well-conducted randomized controlled studies are nearly impossible to perform in this population, the decision to pursue a single- versus two-stage reconstruction should ultimately be determined based on individual patient co-morbidities, the size and etiology of defect, and the type of free tissue transfer planned.

The Cardioplastic Approach to the Treatment of Infected Aortic Grafts.

BACKGROUND: Aortic graft infection (AGI) is a rare complication following reconstructive aortic surgery, yet it represents a significant source of morbidity and mortality. There is no consensus regarding the optimal surgical management, due in part to the small cohorts of patient reports. Pedicled muscle or omental flap coverage of AGI has been shown to improve outcomes, making them a valuable consideration in the treatment algorithm. Thus, we aim to compile and evaluate cases of autologous vascularized tissue (AVT) in the treatment of infected aortic grafts, summarizing location specific trends, treatments, and outcomes. METHODS: A comprehensive review of peer-reviewed literature regarding the management of AGI was performed. Data collected included patient characteristics, original procedure, pathogen, infection location, tissue utilized, technique of tissue isolation and delivery, staging, outcome, length of follow-up, and level of evidence. RESULTS: Ninety-four cases of AGI managed with AVT transfer were identified. Infection of ascending aorta grafts accounted for 59% of cases, followed by a combination of ascending aorta and aortic arch (21%), the descending thoracic aorta (18%), and the thoracoabdominal aorta (2%). The infected graft was preserved in 81% of cases, followed by debridement and AVT coverage. The omentum was the most commonly applied flap (69%) for all divisions of the aorta followed by the pectoralis major (19%), the rectus abdominis (5%), and latissimus dorsi (4%). Mortality was limited, and the Powered by Editorial Manager and ProduXion Manager from Aries Systems Corporation overall survival was 93% (7 deaths), with a mean follow-up of 33.5 months. CONCLUSIONS: Autologous vascularized tissue coverage has proven to be a successful approach for treatment of infected aortic grafts. Although the incidence of AGI is rare, it represents an area of scarce evidence-based literature that warrants increased attention and surgical refinement. These results, which show a remarkably low infection-related mortality rate (3%), should encourage interdisciplinary collaboration with the plastic surgeon, cardiothoracic surgeon, and infectious disease specialists with the goal of improving outcomes in the treatment of infected aortic grafts.

Analysis of Scalp and Forehead Injuries in a Level I Trauma Center.

Traumatic scalp and forehead injuries are frequently encountered in the acute setting in Level I trauma centers. This is a Level IV Therapeutic/Care Management article describing a retrospective review that analyzed a single Plastic and Reconstructive surgeon's experience treating these injuries in patients, over an 8-year period from 2006 to 2014. Fewer complications were seen in patients treated within 7 days of injury. When treating these patients, a surgeon should possess several key attributes. The ability to perform adequate primary debridement, knowledge, and familiarity with the intricate anatomy in this region, and experience with simple and complex reconstructive algorithms-are all crucial to obtaining optimal functional and aesthetic outcomes in this anatomic region. The authors' results support the idea that a plastic and reconstructive surgery service is an indispensable resource in the high-level acute trauma setting.

Role of tissue expansion in abdominal wall reconstruction: A systematic evidence-based review.

BACKGROUND: Tissue expanders (TEs) can be used to assist primary closure of complicated hernias and large abdominal wall defects. However, there is no consensus regarding the optimal technique, use, or associated risk of TE in abdominal wall reconstruction. METHODS: A systematic search of PubMed and Embase databases was conducted to identify articles reporting abdominal wall reconstruction with TE techniques. English articles published between 1980 and 2016 were included on the basis of the following inclusion criteria: two-stage TE surgical technique, >3 cases, reporting of postoperative complications, hernia recurrence, and patient-based clinical data. RESULTS: Fourteen studies containing 103 patients (85 adults and 18 children) were identified for analysis. Most patients presented with a skin-grafted ventral hernia (n = 86). The etiology of the hernia was from trauma or prior abdominal surgery. The remaining patients had TE placed before organ transplantation (n = 12) or for congenital abdominal wall defects (n = 5). The location for expander placement was subcutaneous (n = 74), between the internal and external obliques (n = 26), posterior to the rectus sheath (n = 2), and intra-peritoneal (n = 1). Postoperative infections and implant-related problems were the most commonly reported complications after Stage I. The most common complication after Stage II was recurrent hernia, which was observed in 12 patients (11.7%). Five patients with TE died. Complications and mortality were more prevalent in children, immunosuppressed patients, and those with chronic illnesses. CONCLUSIONS: Tissue expansion for abdominal wall reconstruction can be successfully used for a variety of carefully selected patients with an acceptable complication and risk profile.

Combined submuscular tissue expansion and anterior component separation technique for abdominal wall reconstruction: Long-term outcome analysis.

BACKGROUND: We report the long-term outcome analysis of 12 patients who underwent two-stage abdominal wall reconstruction using combined submuscular tissue expansion and anterior components separation (CS) technique. METHODS: Outcome measures were (1) the patients were assessed for the presence or absence of recurrence; (2) patient-reported outcomes on physical functioning in relation with the abdominal wall reconstruction were evaluated using the SF 36-item health survey. RESULTS: The mean age, average expansion volume, and mean time expansion were 37.5 years, 1250 cc, and 9.5 weeks, respectively. The average soft tissue deficiency size was 15.5 (width) × 19.5 (length) cm2. The average fascial defect was 17 (width) × 21.5 (length) cm2. No mesh-assisted technique was required. Primary closure was obtained in all. The average follow-up was 39.6 months. Hernia recurrence was noted in one patient (8.3%). All 12 patients completed the SF 36-item health survey. Moreover, 75% of the patients reported 100%, indicating "Not limited in vigorous activities," and 25% indicated "limited a little." All patients reported 100% "not limited at all" in lifting or carrying groceries, climbing several flights of stairs, climbing one flight of stairs, bending, kneeling, stooping, walking more than a mile, walking several blocks, walking one block, bathing, or dressing. CONCLUSIONS: Parietal laxity obtained with tissue expansion increases the possibility of direct closure of the fascial layer, skin, and subcutaneous tissue components. Combined use of tissue expansion and CS may result in favorable long-term outcomes as evidenced by patient-reported physical functioning data and low rate of hernia recurrence.

Recipient vessels for microsurgical flaps to the abdomen: A systematic review.

BACKGROUND: Large soft tissue defects of the abdominal wall resulting from various reasons may require free tissue transfer. METHODS: A literature search of PubMed and Cochrane electronic databases was conducted to identify articles involving abdominal wall reconstruction (AWR) with microsurgical flap. Number of cases, etiology, and reconstruction site, type of microsurgical flap and recipient vessels were analyzed. RESULTS: Thirty-eight articles published between 1983 and 2016 reported on 149 patients undergoing free flap AWR. TFL was used in 43 patients (28.8%), LAD in 43 (28.8%), and ALT in 28 (18.7%). Conjoined ALT and TFL flap was reported in 24 patients (16.1%). The inferior epigastric artery/vein were the most commonly utilized recipient vessels (n = 43 patients). Intraperitoneal vessels were used in 18 cases, the gastroepiploic vessels being the most common (n = 9). Femoral vessels were used directly or along with a vein graft in 14 patients. AV loop or vein graft was reported in 46 patients. Great saphenous vein rerouting was used in 8 cases. DLCF vessels were used in 2 patients to support an AV loop or directly the pedicle of a microsurgical flap. The internal thoracic vessels were used in only 3 patients. CONCLUSIONS: The current review analyzed articles on AWR using microsurgical flaps with a special emphasis on the recipient vessels. The literature review demonstrated that there is no standard approach to repair a complex abdominal defect given the diversity of patient population. The choice of microsurgical flap and selection of recipient vessels should be tailored to the individual patient's circumstances.
