PURPOSE Within the academic surgical setting resident involvement may confer longer operative times. The increasing pressures to maximize clinical productivity and decreasing reimbursement rates, however, may conflict with these principles. This study calculates the opportunity cost of resident involvement in craniofacial surgery. METHODS Retrospective analysis was conducted with patients who underwent craniofacial procedures from the American College of Surgeons National Surgical Quality Improvement Program database from 2005 to 2012. Patients were selected based on relevant Current Procedural Terminology codes for craniofacial pathologies (ie, trauma, head and neck reconstruction, orthognathic surgery, and facial reanimation). Variables included patient demographics, operative time, and presence or absence of resident trainee. Average relative value units were calculated to determine the opportunity cost of resident involvement for each craniofacial procedure. RESULTS In total, 2096 patients were identified through the American College of Surgeons National Surgical Quality Improvement Program database from 2005 to 2012. Resident involvement was associated with a statistically significant higher operative time (P

BACKGROUND Blood loss and subsequent transfusion are key concerns in the surgical management of craniosynostosis, and have been associated with increased morbidity, requirement for intensive care admission and increased length of hospital stay. Patient blood management guidelines advocate treatment of anemia before elective surgical procedures where significant blood loss is anticipated. At present there is little evidence in the literature investigating the clinical value of this practice in pediatric craniofacial surgery. AIMS The authors examined the effect of preoperative oral iron supplementation on blood loss and transfusion rates in a national pediatric craniofacial unit. METHODS A total of 157 patients were included in a retrospective and prospective observational cohort study conducted between July 2011 and November 2016. Eighty-five (85) patients included in the preoperative iron supplementation group were prescribed oral ferrous fumarate before total cranial vault reconstruction, frontal-orbital advancement or extended strip cranial vault remodeling procedures. This cohort was retrospectively compared to seventy-two (72) consecutive patients who did not receive iron supplementation. RESULTS Calculated blood loss was 51.3 mL/kg in the intervention group, and 56.65 mL/kg in the control group. Transfusion rate and mean volumes for the intervention group were 85.9% and 25 mL/kg. The control group had transfusion rate of 86.1% with mean transfused volume of 24.7 mL/kg. These differences were not statistically significant. Intraoperative tranexamic acid was associated with significantly reduced transfusion volumes overall. CONCLUSIONS This study did not show a statistically significant benefit to preoperative iron supplementation. Secondary outcomes of this study showed a statistically significant difference in estimated versus calculated intraoperative blood loss. Further research in to specific iron supplementation protocols is indicated.

Implicit bias can lead to discrimination of certain populations within healthcare. Representation in medical literature is no exception and it is hypothesized that images with lighter skin tone are more prevalent than darker skin tones in craniofacial literature. Clinical photographs and figure graphics from 5 journals were examined for pre-defined years. Annals of Plastic Surgery, Aesthetic Surgery Journal, Journal of Craniofacial Surgery, Journal of Plastic, Reconstructive and Aesthetic Surgery, and Plastic and Reconstructive Surgery journals were reviewed. All craniofacial-focused articles containing at least one color image depicting human skin were included. 10,477 images and 627 graphics were evaluated using the Fitzpatrick scale as a guide. Most journals trended toward broader inclusion of nonwhite photographs and graphics over time. In 2016, 47% of articles published in Journal of Craniofacial Surgery included nonwhite images compared to Annals of Plastic Surgery (16%), Aesthetic Surgery Journal (40%), Journal of Plastic, Reconstructive and Aesthetic Surgery (25%), and Plastic and Reconstructive Surgery (7%). Comparison of domestic and international publications demonstrated that author's country of origin impacted the percentage of nonwhite clinical photographs for most journals. Comparisons of publications by country demonstrated increased diversity in Asia and the Middle East for clinical photographs but not graphics. The frequency of nonwhite figure graphics was staggeringly low, identified in only 18 articles across all journals and years. Craniofacial literature more commonly reflects white skin tones. The trend over time suggests increasing inclusion of racial diversity in clinical photographs; however, figure graphics remain less racially diverse. Time, country of origin, and publishing journal appear to play a role.

Background Bioabsorbable systems have been commonly used in pediatric patients for primary cranioplasty and other related surgeries. However, subcutaneous swelling, a unique complication related to bioabsorbable osteosynthesis, is a concern. Differences in the incidence of subcutaneous swelling, depending on the bioabsorbable material used to construct the plate, are still unknown. Methods The authors retrospectively reviewed all incidences of subcutaneous swelling related to resorbable systems used during primary cranioplasty for patients with craniosynostosis at their hospital between 2014 and 2018 during a 12-month follow-up period. Furthermore, the authors reviewed all published English-language articles (since 1995) on subcutaneous swelling in bioabsorbable systems used for craniosynostosis. Results The most common resorbable systems used in the literature were divided into 2 groups: mixtures of poly D-lactic acid and polyglycolic acid, and mixtures of poly D- and L-lactic acid. In patients for whom poly D-lactic acid and polyglycolic acid were used, the incidence of subcutaneous swelling during resorption was 0% to 4.2% between 3 and 9 months of follow-up. In patients for whom poly D- and L-lactic acid was used, subcutaneous swelling during resorption occurred in 5% to 16.7% of these patients between 6 and 12 months of follow-up. All cases resolved spontaneously after complete absorption of the plate. Conclusions It was difficult to determine which system had the lowest incidence of subcutaneous swelling. The thickness of each resorbable system and the thickness of the infants' scalps were different in each study. However, subcutaneous swelling occurred in every resorbable system. Therefore, preoperative counseling and careful follow-up are necessary.

Purpose The aim of this study was to show the displacements and strain induced by the supraorbital band advancement during a craniofacial surgery for an anterior plagiocephaly on the orbital bones and the orbital content thanks to a numerical surgical simulation using the finite element method. Methods A three-dimensional (3D) finite element model of a child with an anterior plagiocephaly was entirely created from a tomodensitometry of a patient followed by our Craniofacial Pediatric team. Data of the tomodensitometry were computed with Slicer 3D to re-create the orbit geometry. Mesh production, properties of the model, and simulations of the fronto-orbital advancement were conducted on Hyperworks software (Altair Engineering, Inc., Detroit, MI, USA). Results The resulting 3D Finite Element Model was used to perform the supraorbital advancement simulation. Displacement and strain patterns were studied for orbital bones, oculomotor muscles, and eyeballs. Relative high strain in the both trochlear area and excycloration of the right orbit are among the most interesting results as torsional strabismus as V-pattern strabismus are often described in children with an anterior plagiocephaly. Conclusions This pediatric Finite-Element Model of both orbits of a child with an anterior plagiocephaly showed the impact of the fronto-orbital advancement on the oculomotor system. This model described the relationship between the craniofacial surgery and the strabismus in the unilateral coronal synostosis. The advantages of this model are the many opportunities for improvement, including postoperative period and additional surgical procedures.

A total of 47 patients who underwent the craniofacial implantation of unsintered hydroxyapatite particles and a poly-L-lactide device were evaluated for clinical local findings and computed tomography (CT) images after about 6 months. Long-term follow-up of 3 patients was done from 5 to 11 years. The patients underwent CT imaging pre- and postoperatively, while local clinical examination was done upon follow-up. For the 3 patients who were followed up for more than 5 years, implant changes were evaluated by using CT. Computed tomography revealed 3 patients of dislocation, 2 patients of insufficient bone union, and 3 patients of implant breakage. All patients healed well with no complications requiring a secondary operation. The CT findings of the long-term cases revealed the following: a plate and screw were still present 5 years postsurgery (patient 1), mesh implants were completely resorbed after 9 years and 6 months (patient 2), and plates were almost resorbed after 11 years but some of their shapes remained (patient 3).The unsintered hydroxyapatite/poly-L-lactide device is useful in the maxillofacial region in terms of strength and radiographic contrast. However, since the absorption rate is slow, it is necessary to keep in mind its long-term radiographic detectability and the possibility of late-onset granuloma.

Background In the United States, the use of herbal supplements on a regular basis ranges from 32% to 97%. Prevalence of supplement use is particularly elevated after facial surgery. It has been reported as high as 50%. Unfortunately, there is a paucity of literature on the dietary use of supplements. They are not regulated by the FDA. Often, they are not reported by patients. This study examines the role of dietary supplements as adjuncts to healing in craniofacial and facial aesthetic surgeries. Methods A comprehensive literature review was conducted using MEDLINE, PubMed, and EMBASE. Databases were screened for papers describing the use of supplements in craniofacial procedures in adult patients using relevant search terms. Data on criteria, outcomes, and patient satisfaction were collected. Results A total of 19 articles were selected from the 806 identified. Fifteen different supplements or combinations of supplements have been studied for use in facial surgeries. Of these 15 supplements, the following demonstrated potential healing benefits: dry ivy leaf extract, Nazalzem ointment (vitamin A and dexpanthenol), combination nasal sprays (phospholipids, fatty acids, vitamin A, and vitamin E), Saireito pills, topical olive oil, yunnan baiyao, melilotus extract, arnica, and combination arnica and ledum. Arnica is the most commonly studied supplement in a variety of facial operations. Conclusions There is ample evidence to support a role for the use of certain dietary supplements to optimize wound healing in craniofacial and facial aesthetic surgery. Controlled diet and use of appropriate supplements may have a synergistic beneficial effect on wound healing following craniofacial surgery. However, there is a need for additional reporting to allow for the creation of stronger guidelines and increased patient screening, reporting, and compliance.

The aim of this report is to describe the combination of Crouzon syndrome and acanthosis nigricans with fibrous dysplasia of the maxilla. The diagnosis of fibrous dysplasia was confirmed clinically and pathologically during Le Fort III osteotomy and midface advancement with distraction osteogenesis. Crouzon syndrome with acanthosis nigricans is a known syndrome with an incidence of 1:1,000,000. This is the first report in the literature of Crouzon syndrome and acanthosis nigricans combined with fibrous dysplasia. As all 3 pathologies are related to fibroblasts, they may be different manifestations of malfunction of a single molecular pathway. The detection of fibrous dysplasia in a patient with Crouzon syndrome and acanthosis nigricans is important because it may complicate midface osteotomies and fixation of the hardware on the bones during craniofacial surgery.

Craniomaxillofacial surgery has the characteristics of complex anatomical structure, narrow surgical field, and easy damage to nerves, blood vessels, and other structures. Compared with the traditional bare-hand operation, robot-assisted craniofacial surgery is expected to achieve a more stable and accurate surgical operation. So we have developed a robot-assisted craniofacial surgery system. A compact mechanism design was adopted for the robot system, integrates with visual and force perception modules. The motion analysis and working space analysis are carried out on the mechanical structure. The binocular vision module is integrated and the robot hand-eye calibration process was completed. The target tracking method based on staple is used to achieve tracking and monitoring of the target area. A distributed robot control system based on CAN bus technology is designed, and a position-based visual servo control method is adopted. Then the precision test of the robot system prototype and the drilling experiment of the 3D printed mandible model were carried out. The average pixel error of the vision module is 0.15 pixels. Based on the staple tracking method, the average center error rate of the image is 0.3175 mm, and the overlap rate is 88.76%. The drilling experiment of the mandible model showed that the average entrance position error is 1.76 ± 0.36 mm, the average target position error is 1.62 ± 0.27 mm, and the angle error is 5.36 ± 0.31 degrees. The designed craniofacial robot system can better assist surgeons to complete the mandibular osteotomy.

Pre-emptive planning to optimize safety and outcome is a defining principle of pediatric craniofacial surgery, in which "procedures that come before" should enhance and not compromise procedures that are planned to follow.A technical modification of fronto-orbital advancement/remodeling in 2-stage hypertelorism surgery for craniofrontonasal dysplasia is presented, where orbital hypertelorism is accompanied by coronal craniosynostosis. Fronto-orbital advancement/remodeling undertaken by this approach preserves bone in the supero-lateral bandeau and provides optimal quality bone stock for the subsequent orbital box shift osteotomy. In this way the second procedure is protected and enhanced by optimal planning of the primary procedure, with potential benefits to safety, quality, and outcome of the final result.

Orbital fractures pose specific challenge in its surgical management. One of the greatest challenges is to obtain satisfactory restoration of normal orbital volume and globe projection following traumatic injury, due to the inability of the surgeon to gain adequate visibility and to verify proper implant position and placement during the operation. Surgical navigation is a very helpful tool when dealing with the reconstruction of such orbital fractures. During the training of the craniofacial fellowship learning to recognize the orbital floor boundaries is essential for the correct implant placement for reconstruction, their identification is a critical step, which may be assisted by intraoperative virtual navigation. Six patients were surgically treated for orbital floor fracture with intraoperative virtual navigation. The clinical evaluation showed no complications such as enophtalmos, exophtalmos or dystopia in all the patients 2 months post operatively and a correct implant/graft position.During surgery, navigation provides exact determination of transverse, cranio-caudal and postero-anterior dimensions within the orbit and precise control of the position of implants/bone grafts.This tool aids consistently on the craniofacial surgery fellow's formation, as it facilitates the identification of the bony floor boundaries and verifies the correct placement of the implants/bone grafts. It is routinely use could help to avoid implants/bone grafts misplacement not only for craniofacial surgeon's fellow, but for all the orbital surgeons.

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.

Utilization, wastage, and adverse consequences of assigning one full red blood cell (RBC) unit were investigated for children undergoing craniosynostosis surgery. The authors hypothesized that significant RBC wastage in the perioperative period exists for pediatric craniofacial surgery. The authors sought to determine what factors could guide patient-specific blood product preparation by evaluating utilization and wastage of RBCs in pediatric patients undergoing surgical correction of craniosynostosis. Eighty-five children with craniosynostosis undergoing surgical correction at our institution between July 2013 and June 2015 were identified. Fifty-three patients received RBC transfusion in the perioperative period, while 32 patients were not transfused. Primary outcome measures were intraoperative, postoperative, and total percent of RBC wastage. Secondary analysis compared the impact of patient weight and procedure type on perioperative RBC wastage. Of the 53 patients who received perioperative RBC transfusion, 35 patients received a volume of blood less than the full volume of the RBC unit while 18 patients received the full volume of blood. There was no significant relationship between perioperative RBC wastage, the type of craniofacial procedure performed, or the duration of surgical time. Children who received a perioperative transfusion and had RBC wastage weighed significantly less than those who received a full volume. These findings suggest that for craniofacial surgical patients weighing less than 10 kg, a protocol that splits cross-matched RBC units can decrease perioperative RBC wastage and blood donor exposure. A future prospective study will determine the success of this intervention as well as the potential to decrease exposure to multiple blood donors.

BACKGROUND The purpose of this study is to review 10 years of surgical experience in the management of Apert syndrome, focusing on an updated algorithm which includes hand reconstruction and posterior vault distraction osteogenesis (PVDO). Additionally, the authors compare PVDO, which is currently used, with fronto-orbital advancement (FOA), which was utilized in a previous algorithm. METHODS An observational retrospective study was performed on consecutive patients with Apert syndrome who underwent upper and lower limb reconstruction and craniofacial surgery between 2007 and 2017. A modified Clavien-Dindo surgical complication scale was used to stratify complications between PVDO and FOA. Demographic, surgical, and outcome data was also recorded. The blood transfusion rate between PVDO and FOA was also assessed and compared utilizing the Student t test. RESULTS The present study included 69 patients with Apert syndrome (34 males and 35 females). Craniofacial surgeries were performed on a total of 38 patients. A total of 210 operations were performed on the respective upper and lower limbs of patients included in this study. A total of 18 patients underwent PVDO (n = 9) and FOA (n = 9). Posterior vault distraction osteogenesis required significantly less transfused blood volume than FOA (P

Introduction Neck pain is common in the post-operative period after craniofacial procedures. If patients present with neck pain and torticollis, it could be a manifestation of atlantoaxial rotatory subluxlation (AARS), which describes a rare condition in which there is lateral displacement of C1 relative to C2. When this occurs in the post-operative patient, it is termed Grisel syndrome. In this case series, we report on 3 patients diagnosed with Grisel syndrome after a craniofacial procedure. Methods A retrospective chart review of a single craniofacial surgeon at a pediatric hospital was conducted over the last 3 decades. Demographics, procedures performed, and management strategies of AARS were included for review. Results Three patients were identified who were diagnosed with Grisel syndrome after a craniofacial procedure and required inpatient cervical traction. All patients presented with torticollis within 1 week of their operation. Conservative management was ineffective, and all 3 patients were admitted for inpatient cervical traction, for an average of 13 days followed by an average of 47 days of outpatient therapy. No patients showed any signs of recurrence after removal of outpatient traction device. Conclusion Grisel syndrome is a rare, but serious complication of craniofacial procedures. Physicians caring for these patients must have a high degree of suspicion if a patient with a recent craniofacial procedure presents with torticollis. Delaying the initiation of therapy has been shown to lead to higher rates of recurrence and increases the likelihood that patients will require surgical intervention.

Purpose: One of the most characteristic features in premature craniosynostosis is fronto-orbital retrusion. The standardized surgical technique of fronto-orbital advancement (FOA) can treat this (some) deformity, such as bilateral coronal synostosis. The purpose of the study is to investigate an available method to assess the postoperative outcome of the craniofacial surgery. Methods: From 2010 to 2015, 6 pediatric patients were taken the FOA in the Department of Burn and Plastic Surgery in the Children‘s Hospital of Nanjing Medical University. All the patients were performed the computed tomography (CT) scan preoperatively and postoperatively. The CT databases were processed by DICOM files into MIMICS 16.0 software, which were automatically calculated into orbital volume and orbital roof and base surface area. T-test was used to compare measured values before and after surgery. P 0.05, there was no significant statistical difference. Conclusions: Fronto-orbital advancement can successfully improve morphological orbital deformities in children with premature craniosynostosis, but much less for maxillary. The computer-assisted technique can present a measurement of FOA preoperatively and postoperatively, which make the evaluation intuitive.

Stem cells, which were initially elucidated in the 1960s, are characterized by their ability to continuously renew themselves to differentiate into multiple cellular types. For this reason, they remain the subject of intensive research, for their potential to treat certain diseases. In craniofacial surgery, tissue engineering using stem cells can be employed in various techniques. These include 3D printing, which has the potential to regenerate dental, oral, and craniofacial structures, once lost to congenital anomalies, trauma and other diseases like cancer. With the growing battery of information about stem cells and their potential translation from research to clinical practice, it is important to outline what is the basic layout of a stem cell research facility.

BACKGROUND Virtual surgical planning (VSP) is increasingly described in craniofacial surgery literature. However, the quality of the literature that has been published is unknown. The objective of this systematic review was to determine the level of evidence of published articles on VSP. METHODS In this systematic review, PubMed, Web of Science, and ScienceDirect databases were queried for key terms in craniofacial VSP. Inclusion and exclusion criteria concentrated on patient-specific surgical outcomes in studies that could be rated for level of evidence. The articles were ranked according to their level of evidence, with level I being the highest level of evidence (randomized-controlled trials) and level V being the lowest (eg, case reports). RESULTS The initial keyword search yielded 1524 articles, 273 of which were ranked and included in the systematic review. The average level of evidence for an article published was 4.1 (between level IV and level V). Level IV was the most common level of evidence (65.6%), followed by level V (24.9%), level III (7.3%), level II (2.2%), respectively. There were not any level I articles. The most common study type was case series, accounting for 68.1% of the studies, followed by case reports (23.0%), case-control studies (4.7%), cohort studies (3.3%), and randomized controlled trials (1.1%), respectively. CONCLUSION Although the quantity of craniofacial VSP studies has proliferated, the quality of the studies has not. In order for VSP literature to feature a higher level of evidence, future studies would require more sophisticated study design, such as prospective cohort or prospective randomized control trials.

Despite the advent of stereolithography in craniofacial surgery for creating surgical guides and custom synthetic scaffolds, little is known about the feasibility of computer-aided design/computer-aided manufacturing (CAD/CAM) milling of freeze-dried allogeneic bone blocks following previously designed volumetric graft plans. The aim of this technical report is to present a methodology for CAD/CAM milling to achieve the volume and shape of allogeneic bone blocks as estimated by using a virtual planning software. To perform the current methodology, an ex vivo simulation was performed. The milled allogeneic block presented satisfactory dimensional accuracy as compared with the respective three-dimensional virtual model.

Topical vancomycin has been demonstrated to be safe and effective for reducing surgical site infections (SSIs) following spine surgery in both adults and children, however, there are no studies of its efficacy in reducing SSIs in craniofacial surgery. The SSIs are one of the most common complications following craniofacial surgery. The complexity of craniofacial procedures, use of grafts and implants, long operative durations and larger surgical wounds all contribute to the heightened risk of SSIs in pediatric craniofacial cases. A retrospective review of all open and endoscopic pediatric craniofacial procedures performed between May 2014 and December 2017 at a single children's hospital was conducted to examine SSI rates between patients receiving topical vancomycin and a historical control group. The treatment group received topical vancomycin irrigation before wound closure. An ad-hoc cost analysis was performed to determine the cost-savings associated with topical vancomycin use. A total of 132 craniofacial procedures were performed during the study period, with 50 cases in the control group and 82 cases in the vancomycin group. Overall, SSI rate was 3.03%. Use of topical vancomycin irrigation led to a significant reduction in SSIs (4/50 SSI or 8.0% in control group vs 0/82 or 0% in vancomycin group, P = 0.04). No adverse events were observed with topical vancomycin use. The potential cost-savings associated with the use of topical vancomycin as SSI prophylaxis in this study was $102,152. Addition of topical vancomycin irrigation as routine surgical infection prophylaxis can be an effective and low-cost method for reducing SSI in pediatric craniofacial surgery.

Background Cranial vault surgeries are invasive, extensive procedures with blood transfusions being frequently required. Previous interventions have been described to attempt to decrease the transfusion burden. The objective of this study is to determine if a Pediatric Blood Management (PBM) team can reduce transfusion requirements in children undergoing cranial vault surgery. Methods A protocol was developed which involved preoperative optimization of hemoglobin (Hb), intraoperative use of tranexamic acid, cell saver technology, and blood sparing operative techniques. Patients were preoperatively screened with basic laboratory testing. Retrospective data on 20 consecutive patients who underwent craniofacial surgery prior were used as controls. Prospective data on patients was collected. Results Groups were similar in age and weight. Postoperative Hb measurements were similar, with the control group 10.9 ± 2.2 g/dL and the intervention arm 9.6 + 2.7 g/dL. Discharge Hb concentrations also were similar with 9.6 ± 1.6 g/dL and 9.7 ± 2.5 g/dL in the control and PBM group, respectively. The rate of transfusion decreased from 80% to 42% after protocol implementation (P = 0.007). During the last 6 months of data collection, the transfusion rate decreased further to 17%. Furthermore, 4 patients were found to have von Willebrand disease preoperatively with only 1 requiring a transfusion. Conclusions The authors found that the institution of a PBM team reduced the transfusion burden of patients, including complex patients with von Willebrand disease. The use of a multimodal approach to hematologic management optimized patients for their procedures and helped minimize exposure to transfusion associated complications.

Purpose A significant challenge in surgical education is to provide a meaningful hands-on experience with the pathology the trainee will see in independent practice. Craniofacial anatomy is challenging and unfamiliar to the learner. Methods Using preoperative computed tomography data, the authors produced an accurately sized, three-dimensional (3D) printed model of the congenital craniofacial anatomy of patients treated by the same attending surgeon-PGY4 resident surgeon pair over the course of a 6-month rotation. A preoperative stepwise surgical plan was written by the attending and resident, and the plan was marked on the 3D model by the attending and resident separately. The written and marked plans were measured for accuracy and time to completion. The resident surgeon's applicable milestone levels were assessed. Results Seven congenital craniofacial anomalies met criteria for inclusion: 4 craniosynostosis cases, 2 mandibular distractions, and 1 LeFort I distraction. The number of inaccuracies of the written plan improved from 5 to 0 for sagittal synostosis and 4 to 0 for mandibular distraction. The time to complete the written plan decreased by 22% for sagittal synostosis and 45% for mandibular distraction. The number of inaccuracies of the marked plan decreased from 5 to 0 for sagittal synostosis and 2 to 0 for mandibular distraction. Time to completion of the marked plan decreased by 76% for sagittal synostosis and 50% for mandibular distraction. Milestone scores increased an average of 1.875 levels. Conclusion Three-dimensional printed craniofacial models are a positive addition to resident training and have been objectively quantified to improve the accuracy and time to completion of the surgical plan as well as progression in the plastic surgery milestones.

Background Plastic surgery evaluates residents on milestones. This study defines a model of education including pre and post-test assessments paired with didactics intended for evaluating residents in the unique technical skills of craniofacial surgery. Methods At the first institution, instrument identification, and time/accuracy of burr hole placement, craniotomy, and plating on Saw Bones Craniofacial Models were tested before and after a 7.5-hour craniofacial orthognathic surgery workshop. At the second institution, this was refined, removing plating, eliminating assessment of timing, and shortening didactics to standard osteotomies, instrument names, and common surgical approaches. The study population consisted of junior, mid-level, and senior residents on 2 different University craniofacial services. Results Participant performance was analyzed by level of training: junior, midlevel and senior resident. In the first iteration, resident times improved significantly for all 4 tasks (P = 0.008, 0.035, 0.035, 0.016). Resident accuracy improved significantly for instrument naming (P = 0.003). Except for instrument naming, resident year did not impact improvement (timing: P = 0.062, 0.310, 0.125, 0.334; accuracy: P = 0.029, 0.664, 0.717, 0.306). In the second iteration, resident accuracy improved for all tasks (instrument naming P = 0.00002, burr holes P = 0.0031, craniotomy P = 0.08). There was no difference in rate of improvement between resident cohorts. Conclusion The task-based assessment with resident education on basic craniofacial surgery skills, standard osteotomies, and instrument names directed resident learning and assessed resident knowledge. With the removal of time as a metric, all tasks improved in accuracy. The craniofacial skills task-assessment successfully evaluated milestone attainment in a reproducible model.

Primary pediatric orbital tumors requiring surgery are uncommon and often require multidisciplinary management. Commonly used surgical approaches to the orbit include transconjunctival, transcutaneous (eyelid), transcranial, or extracranial osteotomies. This paper reviews a 10-year experience of cases that required a transcranial or extracranial surgical approach at the Birmingham Children's Hospital. A total of 9 patients were identified between the years 2008 to 2017. Pathologies included rhabdomyosarcoma, juvenile ossifying fibroma, optic nerve glioma, and retinoblastoma. Surgical approaches to the orbit included supraorbital bar osteotomy (transcranial) or lateral orbitotomy (extracranial). Surgical team members included neurosurgery, craniofacial surgery, and ophthalmology. This study aims to review the role of surgery in management as well as the specific indications for performing transcranial or extracranial osteotomies. It also highlights the excellent access achieved with the use of these osteotomies in certain cases, especially when compared with transconjunctival or transcutaneous approaches.

The surgical treatment of nonsyndromic craniosynostosis is one of the most common procedures performed by craniofacial surgeons. However, for residents and fellows, the high degree of difficulty and complex anatomy may result in slow progress along a steep learning curve. This is particularly important in the context of contemporary academic practice, where work-hour limits and other factors restrict operative exposure and opportunities for trainees to learn. These issues have prompted the development of surgical simulation modalities that, while prevalent in other surgical specialties, have not been fully adopted in reconstructive surgery.Among these resources is the Craniofacial Interactive Virtual Assistant - Professional Edition (CIVA-Pro), a procedural cognition simulator that is free of charge. By integrating 3-dimensional virtual animation, voice over, and high-definition intraoperative video, CIVA-Pro describes cardinal craniofacial surgery procedures in an engaging platform. In this study, a detailed, step-by-step description of the fronto-orbital advancement surgical technique to complement the corresponding CIVA-Pro module was presented. This synergistic combination of multimedia educational resources provides a unique didactic option for current trainees to prepare for surgery.

The benefits of using a dedicated team for complex surgeries are well established for certain specialties, but largely unknown for others. The aim of this study was to determine whether management by a dedicated craniofacial team anesthesiologist would impact perioperative outcomes for children undergoing major surgery for craniosynostosis. Sixty-two children undergoing complex cranial vault reconstruction were identified. Fifty-four patients were managed by the craniofacial anesthesia team, while 8 patients were not. Primary outcome measures were calculated blood loss, red blood cell transfusion volume, blood donor exposures, extubation rate, and postoperative complication rate. Secondary outcome measures included intraoperative opioid administration, crystalloid and colloid administration, intraoperative complication rate, and intensive care unit (ICU) and hospital length of stay. Children cared for by the craniofacial team had significantly lower calculated blood loss, reduced red blood cell transfusion volume, fewer blood donor exposures, less crystalloid administration, higher rate of postoperative extubation, fewer postoperative complications, and decreased ICU and hospital length of stay than patients who were managed by noncraniofacial team anesthesiologists. There were no significant differences in demographics, opioid administration, colloid volume administration, or intraoperative complication rates between the 2 groups. Management by a craniofacial team anesthesiologist was associated with improved outcomes in children undergoing major craniofacial reconstructive surgery. While some variability can be attributed to provider-volume relationship, these findings suggest that children may benefit from a subspecialty anesthesia team-based approach for the management of craniofacial surgery, and potentially other similar high-risk cases.

Pediatric craniosynostosis repair with cranial vault reconstructive surgery can be associated with significant blood loss. Tranexamic acid (TXA), an antifibrinolytic agent, has been shown to decrease blood loss and transfusion volume in craniofacial surgery. Nonetheless data regarding the safety of TXA remains limited. The authors describe a case of ulnar artery thrombosis following ulnar arterial line placement in a patient who received TXA for cranial vault reconstructive surgery.

I look back at my decades in the field of plastic and reconstructive and craniofacial surgery, knowing I was the driving force behind its inception in Japan. However, behind me in turn, supporting me, teaching me, and encouraging me during my formative plastic surgery years in the United States and Europe have been many of the true giants in this field, and I will always accord them my total respect and deepest gratitude. Without their knowledge and technique, which they selflessly taught me and my peers, I would certainly never have been able to accomplish so much in the field of plastic and reconstructive surgery, and in particular, craniofacial surgery.

PURPOSE This study evaluated midfacial asymmetry using an alternative method that involved comparing bilateral patterns of the zygomaticomaxillary prominence in a young adult population. MATERIALS AND METHODS Three-dimensional reconstructed images based on computed tomography scans of 100 Koreans (mean age, 24.7 years) were evaluated with reference to lines spaced at 30° intervals and radiating from the center of an interporion line in a superior view. The surface inclination of the zygomaticomaxillary region was quantified on the same reference lines using a 3-dimensional ruler. RESULTS The 30°-interval line (at the level of the zygomaticotemporal suture) was longer on the left side than the right side in both males and females, whereas the left 60°-interval line (at the level of the zygomaticofrontal suture) was longer in females. Comparing the surface protrusion revealed that the zygomaticomaxillary region was more prognathic and inflated on the left side. CONCLUSION Functional deviations are considered to be causes of asymmetric craniofacial growth. Postnatal growth allometry across the circummaxillary sutures as elucidated by this study could be useful information in craniofacial surgery.

The purpose of orthognathic surgery procedures is to manipulate the elements of the facial skeleton to reestablish normal anatomy and function. These elements could be repositioned with the technique known as Le Fort I osteotomy. This technique can be modified to be adapted on each patient, depending on the anomaly presented and the planned objective. The versatility, offered by the modifications of the Le Fort I osteotomy, has taken us to design one that allows the capability to correct the malar region hypoplasia in the same surgical procedure. A total of 9 patients were included with malocclusion as indication for orthognathic surgery who also presented with malar hypoplasia diagnosed clinically and cephalometrically. A modified technique, the "U"-shaped maxillary osteotomy, was performed with excellent functional and aesthetics results, and none of the patients presented complications associated directly to the maxillary osteotomy. Some patients with maxillary zygomatic deficiency combined with malocclusion continue to present a special challenge to clinicians treating these deformities. This technique is useful in improving zygomatic projection in bloc with the Le Fort I advancement without the need to place a bone graft and the advantage of rigid fixation along with the one used in the Le Fort I osteotomy. The U-shaped maxillary osteotomy is a safe, trustworthy, and reproducible technique that allows the resolution of the maxillomalar hypoplasia in a single surgical time, providing satisfactory aesthetic results. Any surgeon with adequate training in orthognathic or craniofacial surgery could perform it and incorporate it to his technical armamentarium.

This article describes 2 patients with complex facial asymmetry characterized by hemiarhinia, microorbitism, palpebral fissure shortening, ipsilateral canthal dystopia, maxillomandibular hypoplasia, and occlusal plane inclination. These unusual phenotypes are part of the oculoauriculo-vertebral spectrum. Their devastating functional, esthetic, and psychologic effects demand the use of different craniofacial surgery techniques, in order to alleviate the profound impact of these pathologies. Initial skeletal balance through bimaxillary distraction osteogenesis and orbital expansion sets the basis for further reconstruction of the nose and periorbital area with local tissue.

The aim of this study was to determine how many papers have been retracted or withdrawn, and for what reason, in journals relating to plastic surgery.PubMed and SCOPUS were used, with the search terms (retracted OR withdrawn) AND (article OR publication OR paper) AND {(plastic surgery) OR (cosmetic surgery) OR (maxillofacial surgery) OR (craniofacial surgery)}. The papers were analyzed and classified according to the reason for retraction or withdrawal, journal name, publication year, and author. In the PubMed and SCOPUS, 227 and 114 titles were found, respectively, from which 34 duplicate titles were removed. An additional 261 titles which did not include "retracted" or "withdrawn" were removed, leaving 46 papers and 6 mined papers were added. The 52 full texts (42 "retracted" and 10 "withdrawn") were analyzed.The most frequent reason for retraction or withdrawal was duplication (17, 32.7%) followed by the author's request (9, 17.3%), plagiarism (7, 13.5%), and lack of permission (5, 9.6%). Retraction was most common in Plast Reconstr Surg (6, 12%) followed by Aesthetic Plast Surg (4, 7.9%), Ann Plast Surg (2, 3.9%), J Plast Reconstr Aesthet Surg (2, 3.9%), and Surg Res (2, 3.9%). Most authors retracted a paper just once; however, 6 authors retracted a paper twice or more. The first retraction was found in 1991, and the number of retractions showed a tendency to increase over time. However, the duplication rate did not change over time (R = 0.178, P = 0.117).Journal reviewers, as well as production editors, should check for duplication, plagiarism, or permission-related problems.

This paper outlines the development and evaluation of a photobook resource to support parents' decision making regarding potential craniofacial surgery for their child. The photobook was developed at a UK Craniofacial Unit and consisted of preoperative and postoperative photographs of patients with craniosynostosis. It was intended to act as a visual adjunct to detailed verbal discussion of surgical treatment options. No changes in the uptake rate of surgery were detected following the introduction of the photobook. An evaluation of parents' views of the photobook indicates that families generally welcomed the resource and did not report any adverse responses. Ethical considerations of the use of such a resource cannot be discounted, and careful presentation of such a resource in the context of a specialist team is recommended.

PURPOSE Temporal hollowing deformity (THD) is a visible concavity/convexity in the temporal fossa; a complication often seen following neurosurgical/craniofacial procedures. Although numerous techniques have been described, no study to date has shown the healthcare costs associated with temporal hollowing correction surgery. Thus, the purpose here is to compare and contrast the direct costs related to temporal cranioplasty using various methods including: liquid poly-methyl-methacrylate (PMMA) implants with screw fixation, prebent, modified titanium mesh implants, and customized cranial implants (CCIs) with dual-purpose design. Understanding the financial implications related to this frequently encountered complication will help to motivate surgeons/healthcare facilities to better prevent and manage THD. METHODS This is a single-surgeon, single-institution retrospective review of 23 THD patients randomly selected from between 2008 and 2015. Cost analysis variables include length of hospital stay, facility/professional fees, implant material fees, payer information, reimbursement rate, and net revenue. RESULTS Of the 23 patients, ages ranged from 23 to 68 years with a mean of 48.3 years (SD 11.6). Within this cohort, 39.1% received dual-purpose PMMA CCIs (CCI PLUS), 17.4% received modified titanium mesh implants, and 43.5% received hand-molded, liquid PMMA implants with screw fixation. Total facility and/or professional charges ranged from $1978.00 to $126478.00. Average total facility charges per patient with dual-purpose CCIs were $34775.89 (SD ± $22205.09) versus $35826.00 (SD ± $23509.93) for modified titanium mesh implants and $46547.90 (SD ± 81061.70) for liquid PMMA implants with screws. Mean length of inpatient stay was 5.7 days (SD = 8.1), and did not differ between implant types (P = 0.387). CONCLUSION Temporal hollowing deformity is an expensive complication post-neurosurgery, and in the most severe form, requires a revision surgery for definitive correction. Therefore, surgeons should take further initiatives to employ reconstructive methods capable of minimizing risk for costly revision surgery, reducing morbidity related to visible deformity and accompanying social stigmata, and improving overall patient satisfaction.

Enophthalmos after a ventriculo-peritoneal (V-P) shunt placement is very rare. Previous defects of the orbital wall with intracranial hypotension can cause enophthalmos after V-P shunting. The authors present 2 patients of enophthalmos with orbital wall defects resulting from anterior clinoidectomy that was performed during previous aneurysmal surgery. Both patients received a V-P shunt for hydrocephalus after subarachnoid hemorrhage. Although the hydrocephalus was improved by V-P shunts in both patients, sunken eyes were observed. The patients received reconstructive surgery of the superior orbital wall using titanium mesh and recovered after surgery without any neurological deficits. Here, the authors present 2 patients of enophthalmos with orbital wall defects treated by orbital wall reconstruction.
