Incidence, Characteristics, and Outcomes of Robin Sequence: A Population-Based Analysis in the United States.

INTRODUCTION: While the literature is replete of clinical studies reporting on the Robin sequence (RS), population-based analyses are scarce with significant variability within the literature in terms of reported incidence, demographic parameters, and outcomes. The authors have conducted a 20-year population-based analysis to guide clinical practice. METHODS: A birth cohort was created from the available datasets in the Healthcare Cost and Utilization Project-Kids' Inpatient Database (HCUP-KID; 2000-2019). Robin sequence patients were identified and further stratified by syndromic status. Incidence, demographic parameters, and outcomes including mortality and tracheostomy rates were computed. A subset analysis comparing the isolated and syndromic cohorts was conducted. Data was analyzed through a χ 2 or t test. RESULTS: The incidence of RS was 5.15:10,000 (95% CI: 4.99-5.31) from a birth cohort of 7.5 million. Overall, 63.3% of the cohort was isolated RS and 36.7% had syndromic RS. Robin sequence patients had a significantly higher rate of cardiac (25.9%) and neurological (8.6%) anomalies compared with the general birth cohort and were most commonly managed in urban teaching hospitals ( P <0.0001). The pooled mortality and tracheostomy rates were 6.6% and 3.6%, respectively. Syndromic status was associated with a longer length of hospital stay (27.8 versus 13.6 d), tracheostomy rate (6.2% versus 2.1%), and mortality (14.1% versus 2.2%) compared with isolated RS ( P <0.0001). CONCLUSIONS: The true incidence of RS is likely higher than previously reported estimates. Isolated RS patients have a low associated mortality and tracheostomy rate and are typically managed in urban teaching hospitals. Syndromic status confers a higher mortality rate, tracheostomy rate, and length of stay compared with nonsyndromic counterparts.

The Montreal Children's Hospital Experience Managing Robin Sequence: An Analysis of Outcomes and Algorithm for Surgical Technique Selection.

BACKGROUND: The development of mandibular distraction osteogenesis (MDO) and tongue-lip adhesion (TLA) has led to significant improvements in respiratory outcomes for the Robin sequence (RS) population. Despite such advances, there continues to be debate regarding management strategies. The authors present their experience managing the RS population with insights on technique selection. METHODS: A retrospective review of RS patients treated at the senior author's institution from 2003 to 2021 was conducted. Baseline patient demographics and clinical parameters including feeding and respiratory status were recorded. Outcomes included the need for tracheostomy or tracheostomy, decannulation rates, and feeding status. Patients were evaluated through overnight oximetry and drug-induced sleep endoscopy (DISE). Outcomes were stratified according to management technique (MDO, TLA, versus conservative) and compared through statistical analysis. RESULTS: Fifty-nine RS patients were included. Twenty-eight were managed conservatively, 19 underwent MDO, 10 underwent TLA, one underwent both TLA and MDO, and one underwent tracheostomy primarily. Overall, 1.7% of the cohort required a tracheostomy and 86% achieved oral feeding after the procedure. The MDO cohort had lower Apgar scores and mean birth weight compared with the conservative and TLA cohorts ( P < 0.05). There were no statistical differences in respiratory and feeding outcomes across all three cohorts. CONCLUSIONS: A therapeutic algorithm was developed with insight into the use of DISE and risk stratification with overnight oximetry to guide procedural selection. Using this approach, safe and satisfactory respiratory outcomes were achieved with a low tracheostomy rate. Risk stratification is possible without polysomnography, and DISE is a promising tool (that requires further validation) for procedural selection in this population. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Atypical Presentation of a Midline Nasal Dermoid with Intracranial Extension.

Although rarer than their lateral orbital counterparts, dermoid cysts are part of any differential diagnosis of a midline nasal mass in the pediatric population. Here we present a case of a nasal dermoid with intracranial extension that presented as a mass appearing at the nasal-cheek junction. This atypical presentation for a nasal dermoid highlights the need for clinicians to remain vigilant and consider midline dermoid cyst as a diagnosis despite an off-midline position on the face.

Bien qu'ils soient plus rares que les kystes orbitaux, les kystes dermoïdes font partie du diagnostic différentiel de masse nasale médiane dans la population pédiatrique. Les auteurs présentent un cas de kyste dermoïde comportant une extension intracrânienne qui a pris la forme d'une masse à la jonction du nez et de la joue. Cette manifestation atypique de kyste dermoïde nasal fait ressortir la nécessité que les cliniciens demeurent vigilants et envisagent ce diagnostic malgré une position décalée de la médiane sur le visage.

The Utility of Online Information Sessions for Medical Student Recruitment in Plastic Surgery: A New Paradigm Amidst the COVID-19 Pandemic.

Background: The COVID-19 pandemic has led to increased barriers for medical students seeking to engage with plastic surgery. Traditional approaches such as pursuing clinical electives broadly are no longer feasible and medical students are seeking innovative approaches for engagement. The current study evaluated the efficacy of online information sessions on medical student perception and proposed a timeline for longitudinal medical student recruitment. Methods: The McGill Plastic and Reconstructive Surgery residency program held an online information session for medical students focusing on a wide array of topics related to plastic surgery and residency. Following the session, an anonymous survey was sent to participants gauging their satisfaction with the event and potential effects it had on career planning. Results: Thirty-four participants completed the survey, comprising more than 60% of annual applicants to Canadian plastic surgery programs. 94% of participants stated that their view of McGill's training program improved and reported a desire for additional sessions from other training programs. 68% of respondents reported being more likely to consider training at McGill and 100% agreed that such sessions could influence their decision to pursue a given training program. Social media was the most common resource used by participants to gain information on training programs. Conclusion: Online information sessions are valuable tools for medical student recruitment and can directly influence their views of a specific training program and affect career planning. Investing in generating high quality content through online forms of communication is paramount as most medical students are turning to these platforms amidst the pandemic.

Historique: La pandémie de COVID-19 a accru les obstacles pour les étudiants en médecine qui souhaitent aller en chirurgie plastique. Il n'est plus possible de recourir aux approches classiques, comme la recherche très vaste de stages cliniques, et les étudiants en médecine cherchent des moyens novateurs de procéder. L'étude actuelle a permis d'évaluer l'efficacité des séances d'information en ligne sur la perception des étudiants en médecine et de proposer un calendrier de recrutement longitudinal de ces étudiants en médecine. Méthodologie: Le programme de résidence en chirurgie reconstructive et plastique de l'Université McGill a tenu une séance d'information en ligne pour les étudiants en médecine sur un vaste éventail de sujets liés à la chirurgie plastique et à la résidence. Après la séance, les participants ont reçu un sondage anonyme pour évaluer leur satisfaction par rapport à l'événement et les effets potentiels sur leur planification de carrière. Résultats: Au total, 34 participants ont rempli le sondage, représentant plus de 60% des candidats annuels aux programmes canadiens en chirurgie plastique. Dans l'ensemble, 94% des participants ont déclaré que leur perception du programme de formation de McGill s'était améliorée et qu'ils souhaitaient participer aux séances d'autres programmes de formation. Par ailleurs, 68% des répondants ont signalé être plus susceptibles d'envisager une formation à McGill et 100% ont convenu que ces séances pouvaient influer sur leur décision d'opter pour un programme de formation donné. Les réseaux sociaux étaient la principale ressource qu'utilisaient les participants pour obtenir de l'information sur les programmes de formation. Conclusion: Les séances d'information en ligne sont des outils précieux pour recruter des étudiants en médecine, peuvent avoir une influence directe sur leurs points de vue au sujet d'un programme de formation donné et peuvent se répercuter sur leur planification de carrière. Il est essentiel d'investir dans la production de contenu de qualité transmis par diverses formes de communications en ligne, car la plupart des étudiants en médecine se tournent vers ces plateformes en cette période de pandémie.

Patient-Specific Implants and Fat Grafting for Contour Deformities Post Craniosynostosis Reconstruction: A Therapeutic Approach.

BACKGROUND: Contour deformities after fronto-orbital advancement for craniosynostosis reconstruction are commonly encountered. There is a paucity of literature describing secondary procedures to correct such deformities with reported outcomes. An approach to defect analysis and procedure selection is lacking. The authors present our experience utilizing fat grafting (FG) and patient-specific implant (PSI) reconstruction as management strategies for this population. METHODS: A retrospective analysis of consecutive patients who underwent secondary onlay PSI or FG for contour deformities after primary craniosynostosis reconstruction was carried out. Patient demographics, defect analysis, surgical approach, postoperative complications, and esthetic outcomes were recorded. Data were pooled across the entire cohort and presented in a descriptive manner. RESULTS: Fourteen patients (36% syndromic and 64% isolated) were identified that either underwent PSI (n = 7) with a mean follow-up of 56.3 weeks, FG (n = 5) with a mean follow-up of 36 weeks or a combination of both (n = 2) for deformities postcraniosynostis surgery. Supraorbital retrusion and bitemporal hollowing were the most common deformities. There were no intraoperative or postoperative complications. All patients achieved Whitaker class I esthetic outcomes and there were no additional revisions during the defined study period. The presence of a significant structural component or large (>5 mm) depression typically necessitated a PSI. CONCLUSIONS: Contour deformities after fronto-orbital advancement reconstruction can be successfully managed using FG and PSI either as a combination procedure or in isolation. The authors have proposed anatomical criteria based on our experience to help guide procedure selection. Future prospective studies would be beneficial in providing more objective assessment criteria.

Efficacy and Complications of Mandibular Distraction Osteogenesis for Airway Obstruction in the Robin Sequence Population: A Comprehensive Literature Review.

INTRODUCTION: Mandibular distraction osteogenesis (MDO) is becoming the procedure of choice for patients with Robin Sequence (RS) as it offers superior long-term respiratory outcomes in avoidance of tracheostomy. Lacking, is an analysis of the short- and long-term complications. To that end, we have conducted a comprehensive review focusing on complications of MDO. MATERIALS AND METHODS: A systematic review of primary clinical studies reporting outcomes and complications of MDO in RS patients. Outcomes included tracheostomy avoidance and decannulation rate. Complications included dental trauma, nerve injury, surgical site infection and hardware failure. Complications were stratified according to distractor type (internal versus external) and age (>2 months versus <2months). RESULTS: A total of 49 studies yielded 1209 patients with a mean follow-up of 43.78 months. The tracheostomy avoidance rate was 94% (n = 817/870) and the mortality rate was 0.99% (n = 12/1209). The complication rate was 28.9% (n = 349/1209) with surgical site infections (10.5%) being most common. Dental and nerve injuries occurred in 7.9% and 3.2% of patients, respectively. Hardware replacement occurred in 1.2% of patients. internal distractors had higher rates of dental injury whereas external distractors had higher technical failure rates. There were no differences in complication rates ( P= 0.200), mortality ( P = 0.94) or tracheostomy avoidance ( P = 0.058) between patients >2months or <2months of age. CONCLUSION: Mandibular distraction osteogenesis is highly reliable and effective with a low mortality and high tracheostomy avoidance rate. There are important complications including nerve and dental injuries which require long-term follow-up. Neonatal patients do not appear to be at higher risk of complications reinforcing the safety of MDO in this population.

Usage trends, perceptions and ethical views regarding social media: A survey of Canadian plastic surgeons.

Parallel to the rise in usage of Social Media (SoMe) worldwide, plastic surgeons are becoming increasingly present online. Although more are being published, there is a paucity of studies regarding academic and international plastic surgeons. The authors sought to determine current usage trends among Canadian plastic surgeons. A 16-item survey concerning usage, post content, perceptions and ethics towards SoMe was sent to academic and esthetic plastic surgeons across Canada. The survey yielded a 14.2% response rate, from which 37% had a single SoMe account for both personal and professional use, with Instagram (36%) being the most preferred platform and only 10% of post content being academically inclined. Surgeons without a professional account seemed to be more likely to believe it is unethical to discuss procedures with patients over SoMe (75% vs. 29%) and were more likely to believe it is unethical to post procedural/intra-operative videos on SoMe (75% vs. 21%). This survey highlights the diverging views regarding the ethics surrounding SoMe usage, which can be influenced by the type of accounts managed by surgeons. The authors hope this can help elucidate more ethical, safe and effective practices of SoMe.

Axilla versus Wrist as the Recipient Site in Vascularized Lymph Node Transfer for Breast Cancer-Related Lymphedema: A Systematic Review and Meta-Analysis.

BACKGROUND: Vascularized lymph node transfers (VLNT) are being used with increasing frequency for the treatment of breast cancer-related lymphedema (BCRL). However, there is a lack of consensus in the surgical field as to which recipient site should be utilized. We, therefore, aim to assess the evidence comparing the wrist and axilla as recipient sites for VLNT in BCRL. METHODS: We conducted a systematic literature review to compare the wrist and axilla as recipient sites for VLNT in BCRL. Demographic data, as well as circumference reduction rate (CRR), excess volume reduction (EVR), postoperative decrease in infections per year, postoperative discontinuation of compression garments, and overall pooled complication rate were extracted from included studies. These were compared through a meta-analysis. RESULTS: A total of 37 studies met the inclusion criteria for a total of 689 patients. VLNTs to the wrist and axilla resulted in a decrease in CRR of 42.1 and 51.5%, and a decrease in EVR of 35.6 and 48.8%, respectively. However, our meta-analysis showed no significant differences between CRR or EVR and between wrist and axilla as recipient sites. Similarly, we found no differences in postoperative decrease in infections per year, postoperative discontinuation of compression garments, and overall pooled complication rate. CONCLUSION: These data suggest noninferiority between the wrist and axilla as recipient sites for VLNT in the context of BCRL. In the absence of randomized, prospective data, we hope these results can be used as an evidence-based reference and facilitate future studies.

SMaRT Assessment Tool: An Innovative Approach for Objective Assessment of Flap Designs.

SUMMARY: The teaching and assessment of ideal surgical markings for local flaps required for optimal aesthetic and functional outcomes remain a challenge in the present era of competency-based surgical education. The authors utilized the bilobed flap for nasal reconstruction as a proof of concept for the development of an innovative objective assessment tool based on statistical shape analysis, with a focus on providing automated, evidence-based, objective, specific, and practical feedback to the learner. The proposed tool is based on Procrustes statistical shape analysis, previously used for the assessment of facial asymmetry in plastic surgery. For performance boundary testing, a series of optimal and suboptimal designs generated in deliberate violation of the established ideals of optimal bilobed flap design were evaluated, and a four-component feedback score of Scale, Mismatch, Rotation, and Translation (SMaRT) was generated. The SMaRT assessment tool demonstrated the capacity to proportionally score a spectrum of designs (n = 36) ranging from subtle to significant variations of optimal, with excellent computational and clinically reasonable performance boundaries. In terms of shape mismatch, changes in SMaRT score also correlated with intended violations in designs away from the ideal flap design. This innovative educational approach could aid in incorporating objective feedback in simulation-based platforms in order to facilitate deliberate practice in flap design, with the potential for adoption in other fields of plastic surgery to automate assessment processes.

Lower extremity postaxial polydactyly: Current literature status and future avenues.

BACKGROUND: Despite lower extremity polydactyly (LEP) representing the most common congenital foot anomaly with functional and psychosocial implications, the literature is devoid of comprehensive, synthesizing reviews. The purpose of the current review is to identify an evidence-based approach to guide clinical management and shed light on reported functional and esthetic outcomes for postaxial polydactyly. METHODS: A scoping systematic review of primary clinical studies was performed. Baseline patient characteristics, diagnostic, and surgical approaches were recorded. Main outcomes included immediate postoperative pain, infections, callouses, scar cosmesis, residual deformities, and difficulty with shoe-wear or mobility. A qualitative synthesis of outcomes was performed, and a therapeutic algorithm was developed. RESULTS: Nine primary studies were identified representing 375 cases of LEP; mean age was 28.8 months (range: 20-40.6 months), and mean follow-up: 42.7 months (range: 1 month-41 years). Ray dominance and the presence of syndactyly were identified as the most important factors for surgical planning; age at surgery was insignificant. A lateral incision approach was used in 78% of cases. Postoperative callouses occurred in 22.1% of cases, infections in 2.5%, and intermittent pain in 11.9%. Significant issues with shoe-wear or mobilization and esthetic residual deformities were reported for 0.78% and 41.2% of cases, respectively. The incidence of residual valgus was 10.6%. CONCLUSION: LEP is most commonly managed with excision of the non-dominant ray and carries excellent long-term functional outcomes, as presented herein. Numerous techniques are discussed to minimize the risk of esthetic sequalae, although the presence of residual valgus remains a concern. A therapeutic algorithm is proposed for the optimal management of LEP.

Breast Implant-associated Anaplastic Large Cell Lymphoma: A Canadian Surgical Oncology Survey.

BACKGROUND: Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) awareness has increased, resulting in concerns regarding the safety of implant-based reconstruction. Breast cancer patients are first seen by surgical oncologists, who are therefore potentially the first health-care professionals to encounter concerns regarding BIA-ALCL. We therefore surveyed surgical oncologists on their understanding of BIA-ALCL to better assess potential effects on plastic surgery practice. METHODS: An anonymous web-based survey consisting of 9 multiple-choice questions was sent to breast surgical oncologists that are members of the Canadian Society of Surgical Oncology (n = 135). RESULTS: Forty-two members responded (n = 42/135, 31%) and all participants were aware of BIA-ALCL. All participants reported that BIA-ALCL has not deterred them from referring patients for implant-based reconstruction. Twenty-two respondents (52%) discuss BIA-ALCL with their patients and 21% (n = 9) believe that BIA-ALCL typically follows a metastatic course. Eight respondents (19%) reported having a poor understanding of BIA-ALCL, while 14% (n = 6) were unable to identify the link to textured implants. There were no statistical differences based on case-load volume. CONCLUSIONS: Approximately half of the respondent Canadian breast surgical oncologists discuss BIA-ALCL with their patients, yet there is a knowledge gap in terms of the epidemiology and clinical-pathological course of BIA-ALCL. It is of utmost importance to ensure that the plastic surgery community aims at including surgical oncologist colleagues in educational platforms regarding BIA-ALCL to ensure collaboration and unity in an effort to offer the most accurate information to patients, and prevent misinformation that may deter patients from seeking implant-based reconstruction.

Perception of Implants among Breast Reconstruction Patients in Montreal.

BACKGROUND: In light of the recent surge of media coverage and social media influence regarding breast implants, it is essential to understand patients' concerns and misconceptions so that we can better serve them. METHODS: The authors designed a survey study for assessing the awareness and perception of patients toward breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) and breast implant illness (BII). In total, 130 patients presenting to the senior author's breast reconstruction clinic completed the survey. The survey assessed patients' knowledge on and their perception of BIA-ALCL and BII. RESULTS: "News article" and "Television" were most often selected as sources of information for BIA-ALCL (21% and 20%, respectively) and BII (20% and 25%, respectively). A total of 100 patients (77%) had previous knowledge of BIA-ALCL. Forty-seven percent (n = 47/100) responded that they were unsure of the fate of a person diagnosed with BIA-ALCL, and 25% (n = 25/100) were unaware of the association between BIA-ALCL and specific implant type. Patients who were unaware of BIA-ALCL prognosis reported being less likely to receive breast implants in the future (P = 0.012, χ2 = 19.48). Eighty-nine patients (68%) had previous knowledge of BII. A total of 60 symptoms were mentioned by patients, with "Fatigue" (12%, n = 26) being cited the most often. CONCLUSIONS: The present survey highlights the importance for plastic surgeons to frequently discuss these entities with their patients. This should be done despite the obscurity of BII, in an effort to offer the best available evidence to our patients.

Operative Time as the Predominant Risk Factor for Transfusion Requirements in Nonsyndromic Craniosynostosis Repair.

Despite recent advances in surgical, anesthetic, and safety protocols in the management of nonsyndromic craniosynostosis (NSC), significant rates of intraoperative blood loss continue to be reported by multiple centers. The purpose of the current study was to examine our center's experience with the surgical correction of NSC in an effort to determine independent risk factors of transfusion requirements. METHODS: A retrospective cohort study of patients with NSC undergoing surgical correction at the Montreal Children's Hospital was carried out. Baseline characteristics and perioperative complications were compared between patients receiving and not receiving transfusions and between those receiving a transfusion in excess or <25 cc/kg. Logistic regression analysis was carried out to determine independent predictors of transfusion requirements. RESULTS: A total of 100 patients met our inclusion criteria with a mean transfusion requirement of 29.6 cc/kg. Eighty-seven patients (87%) required a transfusion, and 45 patients (45%) required a significant (>25 cc/kg) intraoperative transfusion. Regression analysis revealed that increasing length of surgery was the main determinant for intraoperative (P = 0.008; odds ratio, 18.48; 95% CI, 2.14-159.36) and significant (>25 cc/kg) intraoperative (P = 0.004; odds ratio, 1.95; 95% CI, 1.23-3.07) transfusions. CONCLUSIONS: Our findings suggest increasing operative time as the predominant risk factor for intraoperative transfusion requirements. We encourage craniofacial surgeons to consider techniques to streamline the delivery of their selected procedure, in an effort to reduce operative time while minimizing the need for transfusion.

Upper-Extremity Nerve Decompression Under Local Anesthesia: A Systematic Review of Methods for Reduction of Postoperative Pain and Opioid Consumption.

Background: Opioid abuse is a major health concern in North America. Data have shown an alarming increase in opioid-related deaths and complications, which has shed light on current prescription practices across many specialties, including hand surgery. To that end, we sought to conduct a focused literature review to determine the available modalities to decrease postoperative pain and opioid consumption following upper-extremity nerve decompression procedures, taking advantage of the homogeneity and inherent pain pathways of this specific patient cohort. Methods: A systematic review of the literature was conducted. Primary studies evaluating perioperative and intraoperative modalities for postoperative pain reduction and analgesic consumption following upper-extremity nerve decompression procedures under local anesthesia were included. Studies implementing modalities requiring non-hand surgeon expertise (ie, intravenous sedation), as well as studies that include non-nerve decompression procedures, were excluded. Results: A total of 1478 studies were identified, and 9 studies were included after full-text review. Six studies evaluated intraoperative and 3 studies evaluated preoperative and postoperative modalities. Successful interventions included buffered anesthetic, the use of hyaluronidase, and varying techniques and mixtures for anesthetic administration. No successful preoperative or postoperative modalities were identified. Conclusion: Despite data reporting on the dangers associated with current opioid prescription practices, evidence-based modalities to decrease postoperative pain and opioid consumption are limited in general. Several intraoperative modalities do exist, and nonopioid oral analgesics, standardized opioid protocols, and reduced postoperative prescriptions can be used. Large randomized controlled trials evaluating perioperative modalities for pain reduction are needed to further address this issue.

Resorbable Implants for Mandibular Fracture Fixation: A Systematic Review and Meta-Analysis.

Mandibular fractures in adults commonly require rigid fixation to ensure proper occlusion while minimizing infection risks. Numerous centers have assessed the efficacy of resorbable materials as a potential alternative to metallic plates. The purpose of the current systematic review and meta-analysis is to shed light on overall outcomes for resorbable implants and to compare these results to those for metallic counterparts. METHODS: A systematic review of clinical studies reporting outcomes for resorbable plates for mandible fractures was carried out. The reported outcomes were hardware failure/exposure, infection, wound dehiscence, reoperation, malocclusion, and nonunion. The results were pooled descriptively and stratified according to fracture and implant type. A subset meta-analysis of prospective studies comparing metallic and resorbable implants was also carried out. RESULTS: Eighteen studies were included for a total of 455 patients managed with resorbable implants (mean follow-up, 8.95 months) with an overall complication rate of 19.8 % (n = 90/455). Infection (n = 31/455, 6.8%) and wound dehiscence (n = 28/455, 6.2%) were the most common complications. Nonunion occurred in 1.1% (n = 5/455) of patients. Seven studies were included in a meta-analysis, and the rates of adverse events in the resorbable and metallic groups were 18.0% (n = 32/178) and 18.3% (n = 33/180), respectively, with no statistically significant difference between both cohorts (95% CI 0.58, 1.82, P = 0.93). CONCLUSIONS: This study suggests that there are no statistical differences in outcomes for patients with mandible fractures managed with resorbable or metallic implants. In the absence of meta-analyses or large randomized controlled trials, the current study provides surgeons with an evidence-based reference to guide decision-making.

Management of Pediatric Mandibular Fractures Using Resorbable Plates.

INTRODUCTION: Despite there being several clinical studies reporting promising outcomes of resorbable plates for fixation of pediatric mandible fractures, the literature is devoid of large studies or comprehensive reviews assessing safety rates, complications and long-term outcomes. The purpose of the current review is to obtain a global consensus, shed light on efficacy and complications, and provide the reader with evidence-based data to help guide clinical management. METHODS: A systematic review of clinical studies assessing outcomes for resorbable plates in pediatric mandibular fractures was carried out. The main outcomes included infection, hardware failure, hardware exposure, malocclusion, reoperation and nonunion. Overall rates were pooled and stratified by fracture and implant type. RESULTS: Ten studies were included yielding 232 patients with 269 fractures. The mean age at surgery was 8.24 years with a mean follow up of 1.03 years. The overall complication rate was 5.2% (n = 12). Complications included infection (n = 4, 1.7%), hardware exposure (n = 3, 1.29%), wound dehiscence (n = 2, .86%) and intra-oral fistula formation (n = 2, .86%). One patient (0.43%) had malocclusion and none (0%) had hardware failure, nonunion or revision surgery. Patients with multiple fractures (≥ 2) had higher complication rates compared to isolated fractures (12.5% versus 1.7%). CONCLUSION: The use of resorbable plates for pediatric mandibular fractures is a viable option with similar rates of post-operative complications and outcomes compared to standard metallic counterparts. In the absence of large studies or systematic reviews, this study provides craniofacial surgeons with an evidence-based reference to guide decision making and improve informed consent.

Diagnostic and prognostic value of cardiac magnetic resonance in acute myocarditis: a systematic review and meta-analysis.

While diagnostic criteria were elaborated for acute myocarditis using cardiac magnetic resonance (CMR) in 2009, studies have since examined the yield of traditional and novel CMR parameters to achieve greater accuracy and to predict clinical outcomes. The purpose of this systematic review and meta-analysis was to determine the diagnostic and prognostic value of CMR parameters for acute myocarditis. MEDLINE and EMBASE were systematically searched for original studies that reported CMR parameters in adult patients suspected of acute myocarditis. Each CMR parameter's binary prevalence, mean value and standard deviation were extracted. Parameters were meta-analyzed using a random-effects model to generate standardized mean differences. After screening 1492 abstracts, 53 studies were included encompassing 2823 myocarditis patients and 803 controls. Pooled standardized mean differences between myocarditis patients and controls were: T2 mapping time 2.26 (95% CI 1.50-3.02), extracellular volume 1.64 (95% CI 0.87-2.42), LGE percentage 1.30 (95% CI 0.95-1.64), T1 mapping time 1.18 (95% CI 0.35-2.01), T2 ratio 1.17 (95% CI 0.80-1.54), and EGE ratio 0.93 (95% CI 0.66-1.19). Prolonged T1 mapping time had the highest sensitivity (82%), pericardial effusion had the highest specificity (99%). Baseline LV dysfunction and the presence of LGE were predictive of major adverse cardiac events. The results support integration of parametric mapping criteria in the diagnostic criteria for myocarditis. The presence of baseline LV dysfunction and LGE predict patients at higher risk of adverse events.

Routine Postoperative Admission to the Intensive Care Unit Following Repair of Nonsyndromic Craniosynostosis: Is it Necessary?

BACKGROUND: Cranial vault surgery for craniosynostosis is generally managed postoperatively in the intensive care unit (ICU). The purpose of the present study was to examine our center's experience with the postoperative management of otherwise healthy patients with nonsyndromic craniosynostosis (NSC) without routine ICU admission. METHODS: A retrospective cohort study of patients with NSC operated using a variety of vault reshaping techniques in our pediatric center between 2009 and 2017 was carried out. Patients with documented preexisting comorbidities that would have required admission to the ICU regardless of the surgical intervention were excluded. RESULTS: A total of 102 patients were included in the study. Postoperatively, 100 patients (98%) were admitted as planned to a general surgical ward following observation in the recovery room. Two patients (2%) required ICU admission due to adverse intraoperative events. There were no patients who required transfer to the ICU from the recovery area or surgical ward. Within the surgical ward cohort, 6 patients (6%) had minor postoperative complications that were readily managed on the surgical floor. Postoperative anemia requiring transfusion was the most common complication. CONCLUSION: The results from this study suggest that otherwise healthy patients with NSC undergoing cranial vault surgery can potentially be safely managed without routine admission to the ICU postoperatively. Key elements are proper preoperative screening, access to ICU should an adverse intraoperative event occur and necessary postoperative surgical care. The authors hope that this experience will encourage other craniofacial surgeons to reconsider the dogma of routine ICU admission for this patient population.
