Effect on Facial Growth of the Management of Cleft Lip and Palate.

Treatment of cleft lip and palate ordinarily requires multiple interventions spanning the time of birth to adulthood. Restriction of facial growth, a common occurrence in affected children, is due to multiple factors. There are multiple surgical and therapeutic options, which may have influence on facial growth in these patients. As restriction to facial development can have significant implications to form, function, and psychological well-being, practitioners should have an appreciation for the effects of the different cleft therapies to facial growth. We have outlined and thoroughly reviewed in chronological order all of the interventions from birth to adulthood necessary in the comprehensive care of the patient with cleft lip and palate, along with the effects they may or may not have on facial growth.

Combined Primary Cleft Lip and Palate Repair: Is It Safe?

BACKGROUND: Single-stage primary cleft lip and palate (PCLP) repair is controversial in the United States, and most patients are treated with a staged approach. In this study, early postoperative complications of the single-stage approach as compared to primary cleft lip (PCL) or primary cleft palate (PCP) alone were evaluated. This study represents the largest cohort of patients undergoing combined cleft lip and palate repair. METHODS: The American College of Surgeons National Surgical Quality Improvement Program-Pediatric database was used to identify patients undergoing single-stage PCLP, PCL, or PCP repairs. Preoperative factors and postoperative outcomes were compared between the 3 groups, as well as within the PCLP group between patients with and without complications. Univariate and multivariate analyses were performed. RESULTS: A TOTAL OF:: 181 patients were included in the single-stage PCLP group, 1007 in the PCP group and 783 in the PCL group. There was no difference in the rates of early complications between the 3 groups. Within the PCLP group, cardiac risk factors (ß = 35.19; 95% confidence interval [CI] 7.88-75.21; P = 0.04) and complications (ß = 77.31; 95% CI 35.82-118.79; P < 0.001) were significant risk factors for longer operative time. CONCLUSION: Analysis of a national database showed that single-stage PCLP repair is not associated with increased risk of early postoperative complications as compared to primary lip or palate repair alone. In-depth long-term analyses of craniofacial morphology, fistulae rate, speech, and dental outcomes are essential for a comprehensive assessment of the effects of combined cleft lip and palate repair.

Single-Stage Primary Cleft Lip and Palate Repair: A Review of the Literature.

BACKGROUND: Single-stage cleft lip and palate repair is a debated surgical approach. While some studies have described favorable outcomes, concerns include the effect on craniomaxillofacial growth and increased risk of complications. To this date, there has not been a comprehensive appraisal of available data following combined cleft lip and palate repair. METHODS: An extensive literature review was performed to identify all relevant articles. The level of evidence of these articles was graded according to the Oxford Centre for Evidence-Based Medicine Levels of Evidence Scale. RESULTS: A total of 22 relevant articles were identified, all of which were retrospective in nature. Patient age at the time of surgery ranged from 1 month to 10 years, the longest duration of follow-up was 18 years, and the largest study included 106 patients. Review of the literature shows that overall surgical outcomes following combined cleft lip and palate repair are encouraging. An increased rate of postoperative fistulas with associated speech abnormalities in some studies is noteworthy. Importantly, there is no evidence to suggest an impact on craniomaxillofacial growth, and psychosocial outcomes and parental satisfaction seem to be improved with single-stage surgery as compared with the staged approach. CONCLUSIONS: Our review shows overall favorable outcomes associated with combined cleft lip and palate repair. The limited follow-up time or nature of evaluated outcomes in some studies may underrepresent the true rate of adverse events, and highlights the need for additional long-term studies with standardized follow-up. To our knowledge, our review is the first to evaluate existing data regarding outcomes following combined cleft lip and palate repair.

Face Transplantation: An Update for the United States Trauma System.

Face transplantation has evolved over the last 12 years into a safe and feasible reconstructive solution, with good aesthetic and functional outcomes for patients with severe facial defects who are not amenable to reconstruction through conventional and autologous approaches. Among patients who underwent face transplantation to date, a significant proportion did so following trauma, mostly ballistic and thermal injuries. It is therefore important for trauma surgeons who deal with these injuries regularly to be familiar with the literature on face transplantation following traumatic injuries. In this study, we provide a focused review on this topic, with an emphasis on highlighting the limitations of conventional craniomaxillofacial reconstruction, while emphasizing data available on the risks, benefits, surgical indications, contraindications, as well as aesthetic and functional outcomes of face transplantation. The authors also provide an update on all face transplants performed to date including traumatic mechanisms of injury, and extent of defects. They finally describe 2 cases performed by the senior author for patients presenting with devastating facial ballistic and thermal injuries. The authors hope that this work serves as an update for the trauma surgery community regarding the current role and limitations of face transplantation as a craniomaxillofacial reconstructive option for their patient population. This can potentially expedite the reconstructive process for patients who may benefit from face transplantation.

Fenestration of Solid Orbital Implants: Reducing Retrobulbar Hematoma Rate.

PURPOSE: Retrobulbar hematoma is an uncommon but potentially devastating complication following repair of orbital fractures. Since 2007, the senior author routinely fenestrates the solid porous polyethylene implants commonly used for orbital reconstruction. The perforated implant may facilitate drainage of postoperative bleeding and may potentially reduce the risk of retrobulbar hematoma. This study examines the rates of retrobulbar hematoma in patients who underwent orbital fracture reconstruction with placement of fenestrated or nonfenestrated implants. METHODS: A retrospective chart review of patients with orbital fracture reconstruction using an implant performed by the senior author between 2006 and 2016 was conducted. Data collected included age, sex, implant type, and presence of retrobulbar hematoma. RESULTS: One hundred four patients were included in the study. One patient who was treated with a nonperforated implant was found to have a postoperative retrobulbar hematoma. The retrobulbar hematoma did not cause visual changes or increased intraocular pressure, so the patient was observed and did not undergo any surgical intervention. The hematoma resolved spontaneously without further sequela. No patients with fenestrated implants had a retrobulbar hematoma. CONCLUSIONS: Fenestration of solid implants used in orbital floor reconstruction is simple and easy to perform, and may reduce the incidence of postoperative retrobulbar hematoma.

Anthropometric Outcome Measures in Patients With Metopic Craniosynostosis.

PURPOSE: Treatment of metopic craniosynostosis is performed by either fronto-orbital advancement (FOA) or endoscopic-assisted techniques. Interfrontal angle (IFA) is a validated measure of trigonocephaly, but requires a computed tomography scan. The most common direct measure to assess surgical outcome in patients with trigonocephaly is frontal width (ft-ft). The aim of this study is to determine if frontal width correlates with IFA and successful surgical correction 1 year after treatment. A review of current morphologic assessment techniques is also provided. METHODS: Three-dimensional computed tomography scans (preoperative and 1 year postoperative) of patients who underwent FOA (n = 13) or endoscopic (n = 13) treatment of metopic craniosynostosis were reviewed. Age-matched scans of unaffected patients served as controls. Frontal width was measured by a straight line between the bilateral frontotemporal points. Measurements were performed by 2 experienced observers and compared to IFA. RESULTS: Mean frontal width at preoperative scan for endoscopic and open patients was 55 ±â€Š0.6 and 64 ±â€Š0.7 mm, respectively (Z-score 1.6 and -3.7). Mean frontal width at postoperative scan for endoscopic and open patients was 80 ±â€Š0.4 and 81 ±â€Š0.7 mm (Z-score 0.0 for both groups). Frontal width for endoscopic correction significantly correlated with IFA (r = 0.536, P = 0.005), as well as for the open patients (r = 0.704, P < 0.001). CONCLUSION: Frontal width normalizes 1 year after operation, regardless of technique. Advantage of frontal width is that it can be measured in the clinic using a spreading vernier caliper. It correlates well with IFA and can be used as a metric for morphologic outcome.

Comparison of Resorbable Plating Systems: Complications During Degradation.

INTRODUCTION: Several bioresorbable plating systems have become standard in pediatric craniosynostosis reconstruction. A comparison of these systems is needed to aid surgeons in the preoperative planning process. The authors aim to evaluate 1 institution's experience using Resorb-X by KLS Martin and Delta Resorbable Fixation System by Stryker (Stryker Craniomaxillofacial, Kalamazoo, MI). METHODS: A sample of patients with single-suture nonsyndromic craniosynostosis treated at St Louis Children's Hospital between 2007 and 2014 using either Resorb-X or Delta bioresorbable plating systems were reviewed. Only patients with preoperative, immediate, and long-term 3-dimensional photographic images or computed tomography scans were included. A comparison of plating system outcomes was performed to determine the need for clinic and emergency room visits, imaging obtained, and incidence of subsequent surgical procedures due to complications. RESULTS: Forty-six patients (24 Resorb-X and 22 Delta) underwent open repair with bioabsorbable plating for single suture craniosynostosis. The mean age at each imaging time point was similar between the 2 plating systems (P > 0.717). Deformity-specific measures for sagittal (cranial index), metopic (interfrontotemporale), and unicoronal (frontal asymmetry) synostosis were equivalent between the systems at all time points (0.05 < P < 0.904). A single Delta patient developed bilateral scalp cellulitis and abscesses and subsequently required operative intervention and antibiotics. CONCLUSION: Bioabsorbable plating for craniosynostosis in children is effective and has low morbidity. In our experience, the authors did not find a difference between the outcomes and safety profiles between Resorb-X and Delta.

Vascularization is delayed in long nerve constructs compared with nerve grafts.

INTRODUCTION: Nerve regeneration across nerve constructs, such as acellular nerve allografts (ANAs), is inferior to nerve auto/isografts especially in the case of long defect lengths. Vascularization may contribute to poor regeneration. The time course of vascular perfusion within long grafts and constructs was tracked to determine vascularization. METHODS: Male Lewis rat sciatic nerves were transected and repaired with 6 cm isografts or ANAs. At variable days following grafting, animals were perfused with Evans Blue albumin, and grafts were evaluated for vascular perfusion by a blinded observer. RESULTS: Vascularization at mid-graft was re-established within 3-4 days in 6 cm isografts, while it was established after 10 days in 6 cm ANAs. CONCLUSIONS: Vascular perfusion is reestablished over a shorter time course in long isografts when compared with long ANAs. The differences in vascularization of long ANAs compared with auto/isografts suggest regenerative outcomes across ANAs could be affected by vascularization rates. Muscle Nerve 54: 319-321, 2016.

An Alternative Method of Intermaxillary Fixation for Simple Pediatric Mandible Fractures.

PURPOSE: Mandibular fractures represent a substantial portion of facial fractures in the pediatric population. Pediatric mandibles differ from their adult counterparts in the presence of mixed dentition. Avoidance of injury to developing tooth follicles is critical. Simple mandibular fractures can be treated with intermaxillary fixation (IMF) using arch bars or bone screws. This report describes an alternative to these methods using silk sutures and an algorithm to assist in treating simple mandibular fractures in the pediatric population. PATIENTS AND METHODS: A retrospective chart review was performed and the records of 1 surgeon were examined. Pediatric patients who underwent treatment for a mandibular fracture in the operating room from 2011 to 2015 were identified using Common Procedural Terminology codes. Data collected included age, gender, type of fracture, type of treatment used, duration of fixation, and presence of complications. RESULTS: Five patients with a mean age of 6.8 years at presentation were identified. Fracture types were unilateral fractures of the condylar neck (n = 3), bilateral fractures of the condylar head (n = 1), and a unilateral fracture of the condylar head with an associated parasymphyseal fracture (n = 1). IMF was performed in 4 patients using silk sutures, and bone screw fixation was performed in the other patient. No post-treatment complications or malocclusion were reported. Average duration of IMF was 18.5 days. CONCLUSIONS: An algorithm is presented to assist in the treatment of pediatric mandibular fractures. Silk suture fixation is a viable and safe alternative to arch bars or bone screws for routine mandibular fractures.

Maxillomandibular Fixation by Plastic Surgeons: Cost Analysis and Utilization of Resources.

PURPOSE: Maxillomandibular fixation (MMF) can be performed using various techniques. Two common approaches used are arch bars and bone screws. Arch bars are the gold standard and inexpensive, but often require increased procedure time. Bone screws with wire fixation is a popular alternative, but more expensive than arch bars. The differences in costs of care, complications, and operative times between these 2 techniques are analyzed. METHODS: A chart review was conducted on patients treated over the last 12 years at our institution. Forty-four patients with CPT code 21453 (closed reduction of mandible fracture with interdental fixation) with an isolated mandible fracture were used in our data collection. The operating room (OR) costs, procedure duration, and complications for these patients were analyzed. RESULTS: Operative times were significantly shorter for patients treated with bone screws (P < 0.002). The costs for one trip to the OR for either method of fixation did not show any significant differences (P < 0.840). More patients with arch bar fixation (62%) required a second trip to the OR for removal in comparison to those with screw fixation (31%) (P < 0.068). This additional trip to the OR added significant cost. There were no differences in patient complications between these 2 fixation techniques. CONCLUSIONS: The MMF with bone screws represents an attractive alternative to fixation with arch bars in appropriate scenarios. Screw fixation offers reduced costs, fewer trips to the OR, and decreased operative duration without a difference in complications. Cost savings were noted most significantly in a decreased need for secondary procedures in patients who were treated with MMF screws. Screw fixation offers potential for reducing the costs of care in treating patients with minimally displaced or favorable mandible fractures.

Outpatient Alveolar Bone Grafting.

PURPOSE: Alveolar bone graft (ABG) has traditionally been performed with a postoperative inpatient stay secondary to donor site pain. Upon transitioning from an open iliac bone harvesting technique to an Acumed trephine, the authors observed that donor site pain was reduced eliminating an inpatient stay. This study examines the cost savings associated with outpatient ABG surgery. METHODS: A retrospective single-institution review was conducted on all patients who had an ABG performed from 2012 to 2015. Patients were categorized based upon hospital stay: inpatient, observation (23-hour), or outpatient. Cost data reported included: total direct cost, total variable direct cost, fixed direct cost, and the sum of total direct costs for both medical/surgical supplies and operating room costs. T tests were used to determine differences in various cost categories between groups of patients. RESULTS: Sixty-two procedures were performed: 7 procedures were inpatient, 16 observation, and 39 outpatient. The total direct costs averaged $4536 for inpatients, $3222 for the observation group, and $3340 for the outpatient group. Inpatient and outpatient costs were significantly different (P <0.01). Total variable direct costs (P <0.05) and fixed direct costs (P <0.01) were significantly lower in the outpatient/observation group. All costs for the observation group were significantly lower than inpatient costs, but were not significantly different than outpatient costs. There were no readmissions reported. CONCLUSIONS: Cost of an inpatient stay is significantly higher than outpatient or 23-hour observation for ABG procedures. The Acumed trephine technique allows for same-day discharge. In the face of declining reimbursement, safe and cost-efficient treatments are an appealing option.

Anatomical Study of the Intraosseous Pathway of the Infraorbital Nerve.

BACKGROUND: The infraorbital nerve (ION) is at risk for iatrogenic injury during orbital floor repair. The authors aim to anatomically characterize the intraosseous course of the ION between the inferior orbital fissure and infraorbital foramen. METHODS: Ten cadaver heads (20 orbits) were dissected, with exposure of the orbital floor. The ION was identified from the infraorbital fissure to inferior orbital foramen. The presence and caliber of an osseous roof was noted. Distances measured were infraorbital foramen to infraorbital margin; length of the inferior orbital groove; length of the inferior orbital canal; length from the inferior orbital fissure to the infraorbital margin. RESULTS: Three variations of the osseous anatomy around the ION were identified. Four cadavers had no identifiable groove (Type 1, 40%) and the ION was completely roofed throughout its course. Five specimens exhibited a thin, transparent osseous roof over the nerve before forming the true canal, which we describe as a "pseudocanal" (Type 2, 50%). A true groove was seen in both orbits from a single cadaver (Type 3, 10%). Each cadaver had an ION course of the same type on both sides. Mean ±â€ŠSD intraorbital foramen to infraorbital margin distance was 7.1 ±â€Š1.4 mm. Distance from the infraorbital fissure to the infraorbital margin was 28.5 ±â€Š2.3 mm. CONCLUSIONS: The course of the infraorbital nerve can be described as Type 1 (true canal), Type 2 (pseudocanal), and Type 3 (groove and canal). The authors propose that this novel classification system will raise awareness of variations in orbital floor anatomy.

Peripheral nerve injury after local anesthetic injection.

BACKGROUND: A well-known complication of peripheral nerve block is peripheral nerve injury, whether from the needle or toxicity of the medication used. In this study, we sought to determine the extent of damage that results from intrafascicular injection of various commonly used local anesthetics (LAs). METHODS: Sixteen Lewis rats received an intrafascicular injection of saline (control) or 1 of 3 LAs (bupivacaine, lidocaine, or ropivacaine) into the sciatic nerve (n = 4). At a 2-week end point, the sciatic nerves were harvested for histomorphometric and electron microscopic analysis. RESULTS: Animals that received intrafascicular LA injections showed increased severity of injury as compared with control. In particular, there was a significant loss of large-diameter fibers as indicated by decreased counts (P < 0.01 for all LAs) and area (P < 0.01 for all LAs) of remaining fibers in severely injured versus noninjured areas of the nerve. There was a layering of severity of injury with most severely injured areas closest to and noninjured areas furthest from the injection site. Bupivacaine caused more damage to large fibers than the other 2 LAs. In all groups, fascicular transection injury from the needle was observed. Electron microscopy confirmed nerve injury. CONCLUSIONS: Frequently used LAs at traditional concentrations are toxic to and can injure the peripheral nerve. Any combination of motor and/or sensory sequelae may result due to the varying fascicular topography of a nerve.

Supercharge nerve transfer to enhance motor recovery: a laboratory study.

PURPOSE: To investigate the ability of a supercharge end-to-side (SETS) nerve transfer to augment the effect of regenerating native axons in an incomplete rodent sciatic nerve injury model. METHODS: Fifty-four Lewis rats were randomized to 3 groups. The first group was an incomplete recovery model (IRM) of the tibial nerve complemented with an SETS transfer from the peroneal nerve (SETS-IRM). The IRM consisted of tibial nerve transection and immediate repair using a 10-mm fresh tibial isograft to provide some, but incomplete, nerve recovery. The 2 control groups were IRM alone and SETS alone. Nerve histomorphometry, electron microscopy, retrograde labeling, and muscle force testing were performed. RESULTS: Histomorphometry of the distal tibial nerve showed significantly increased myelinated axonal counts in the SETS-IRM group compared with the IRM and SETS groups at 5 and 8 weeks. Retrograde labeling at 8 weeks confirmed increased motoneuron counts in the SETS-IRM group. Functional recovery at 8 weeks showed a significant increase in muscle-specific force in the SETS-IRM group compared with the IRM group. CONCLUSIONS: An SETS transfer enhanced recovery from an incomplete nerve injury as determined by histomorphometry, motoneuron labeling within the spinal cord, and muscle force measurements. CLINICAL RELEVANCE: An SETS distal nerve transfer may be useful in nerve injuries with incomplete regeneration such as proximal Sunderland II- or III-degree injuries, in which long regeneration distance yields prolonged time to muscle reinnervation and suboptimal functional recovery.

Transpalpebral Eyelid Approach for Supraorbital Frontal Craniotomy and Access to the Anterior Cranial Fossa.

SUMMARY: The transpalpebral eyelid approach is an innovative alternative to traditional incisions for exposure of the anterior cranial fossa for neurosurgery. However, there is a paucity of data on this surgical technique in the plastic surgery literature for accessing the anterior cranial fossa. A retrospective review was performed of patients who underwent supraorbital frontal craniotomy using an anterior skull base approach with transpalpebral exposure over 8 years by a single plastic surgeon. Surgical techniques, medical comorbidities, intraoperative complications, and long-term complications were assessed. Twenty patients (mean age 52 ± 12 years, 55% male, 45% female) underwent supraorbital frontal craniotomy using an anterior skull base approach with upper transpalpebral exposure. Operative indications included the following: 75% had anterior communicating aneurysms, with a mean aneurysm size of 5.36 ± 1.91 mm; 10% had meningiomas; 10% had dural fistulas; and 5% had an orbital hemangioma. A total of 60% of patients had a smoking history. No intraoperative complications were encountered, and no cases required conversion to a traditional open approach. Mean length of hospital stay was 3.2 ± 1.5 days. Postoperative imaging revealed no residual or recurrent pathology. Mean follow-up time was 62.2 ± 30.6 months. No long-term neurologic or ophthalmologic complications or infections occurred. No forehead paresthesias, brow ptosis, or brow paralysis were noted. The transpalpebral technique is a safe, minimally invasive method to approach lesions of the anterior cranial fossa. Successful application may require appropriate management of the frontal sinus and supraorbital nerve. This approach does not limit neurosurgical access or results and led to no neurosurgical complications. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Reconstructing the Face of War.

INTRODUCTION: Ongoing combat operations in Iraq, Afghanistan, and other theaters have led to an increase in high energy craniomaxillofacial (CMF) wounds. These challenging injuries are typically associated with complex tissue deficiencies, evolving areas of necrosis, and bony comminution with bone and ballistic fragment sequestrum. Restoring form and function in these combat-sustained CMF injuries is challenging, and frequently requires local and distant tissue transfers. War injuries are different than the isolated trauma seen in the civilian sector. Donor sites are limited on patients with blast injuries and they may have preferences or functional reasons for the decisions to choose flaps from the available donor sites. METHODS: A case series of patients who sustained severe combat-related CMF injury and were treated at Walter Reed National Military Medical Center (WRNMMC) is presented. Our study was exempt from Institutional Review Board review, and appropriate written consent was obtained from all patients included in the study for the use of representative clinical images. RESULTS: Four patients treated by the CMF team at Walter Reed National Military Medical Center are presented. In this study, we highlight their surgical management by the CMF team at WRNMMC, detail their postoperative course, and illustrate the outcomes achieved using representative patient clinical images. We also supplement this case series demonstrating military approaches to complex CMF injuries with CMF reconstructive algorithms utilized by the senior author (EDR) in the management of civilian complex avulsive injuries of the upper, mid, and lower face are thoroughly reviewed. CONCLUSION: While the epidemiology and characteristics of military CMF injuries have been well described, their management remains poorly defined and creates an opportunity for reconstructive principles proven in the civilian sector to be applied in the care of severely wounded service members. The War on Terror marks the first time that microsurgery has been used extensively to reconstruct combat sustained wounds of the CMF region. Our manuscript reviews various options to reconstruct these devastating CMF injuries and emphasizes the need for steady communication between the civilian and military surgical communities to establish the best care for these complex patients.

Autologous Reconstruction of a Face Transplant Candidate.

Since 2005, facial transplantation has emerged as a viable reconstructive option for the most severe defects not amenable to conventional reconstructive techniques, with promising aesthetic and functional outcomes to date. Key facial subunits and midface structures such as the eyelids, lips, and nose are now able to be successfully replaced rather than reconstructed, enabling adequate functional outcomes in even the most extensive defects. However, even in cases of severe facial disfigurement, the decision to proceed with transplantation versus autologous reconstruction remains a source of debate, with no current consensus regarding precise indications and inclusion/exclusion criteria. This report details the case of a candidate referred for face transplantation who ultimately underwent autologous facial reconstruction. Through this representative case, our objective is to clarify the criteria that make a patient a suitable face transplant candidate, as well as to demonstrate the outcomes achievable with a conventional autologous reconstruction, using a methodically planned, multistaged approach.

A Prospective, Randomized, Blinded Trial Comparing Digital Simulation to Textbook for Cleft Surgery Education.

BACKGROUND: Simulation is progressively being integrated into surgical training; however, its utility in plastic surgery has not been well described. The authors present a prospective, randomized, blinded trial comparing digital simulation to a surgical textbook for conceptualization of cleft lip repair. METHODS: Thirty-five medical students were randomized to learning cleft repair using a simulator or a textbook. Participants outlined markings for a standard cleft lip repair before (preintervention) and after (postintervention) 20 minutes of studying their respective resource. Two expert reviewers blindly graded markings according to a 10-point scale, on two separate occasions. Intrarater and interrater reliability were calculated using intraclass correlation coefficients. Paired and independent t tests were performed to compare scoring between study groups. A validated student satisfaction survey was administered to assess the two resources separately. RESULTS: Intrarater grading reliability was excellent for both raters for preintervention and postintervention grading (rater 1, intraclass correlation coefficient = 0.94 and 0.95, respectively; rater 2, intraclass correlation coefficient = 0.60 and 0.92, respectively; p < 0.001). Mean preintervention performances for both groups were comparable (0.82 ± 1.17 versus 0.64 ± 0.95; p = 0.31). Significant improvement from preintervention to postintervention performance was observed in the textbook (0.82 ± 1.17 versus 3.50 ± 1.62; p < 0.001) and simulator (0.64 ± 0.95 versus 6.44 ± 2.03; p < 0.001) groups. However, the simulator group demonstrated a significantly greater improvement (5.81 ± 2.01 versus 2.68 ± 1.49; p < 0.001). Participants reported the simulator to be more effective (p < 0.001) and a clearer tool (p < 0.001), that allowed better learning (p < 0.001) than textbooks. All participants would recommend the simulator to others. CONCLUSION: The authors present evidence from a prospective, randomized, blinded trial supporting online digital simulation as a superior educational resource for novice learners, compared with traditional textbooks.

Facial Trauma Care in the Austere Environment.

As the United States continues to increase its use of Special Operations Forces worldwide, treatment of craniomaxillofacial (CMF) trauma must be adapted to meet the needs of the warfighter. The remoteness of Special Operations can result in potentially longer times until definitive treatment may be reached. A significant portion of Servicemembers incur injury to the CMF region (42%). Severe CMF trauma can result in substantial hemorrhage and airway compromise. These can be immediately life threatening and must be addressed expeditiously. Numerous devices and techniques for airway management have been made available to the forward provider. A thorough review of nonsurgical and surgical airway management of the patient with facial injury for the forward provider and providers at receiving facilities is provided in this article. Techniques to address flail segments of the facial skeleton are critical in minimizing airway compromise in these patients. There are many methods to control hemorrhage from the head and neck region. Hemorrhage control is critical to ensure survival in the austere environment and allow for transport to a definitive care facility. Associated injuries to the cervical spine, globe, skull base, carotid artery, and brain must be carefully evaluated and addressed in these patients. Management of vision- threatening orbital compartment syndrome is critical in patients with CMF injuries. Because the head and neck region remains relatively vulnerable in the warfighter, combat CMF trauma will continue to occur. Forward providers will benefit from a review of the acute treatment of CMF traumatic injury. Properly triaging and treating facial injuries is necessary to afford the best chance of survival for patients with a devastating combat CMF injury.

Free Ulnar Forearm Flap: Design, Elevation, and Utility in Microvascular Nasal Lining Reconstruction.

Reconstruction of the nasal lining has traditionally been performed using the folded radial forearm free flap, given its reliable blood supply, pliability, and familiarity to surgeons with respect to its harvest. More recently, the free ulnar forearm flap has been proposed as an alternative reconstructive option for the nasal lining, with safe and reliable outcomes, and improved donor-site morbidity compared with its radial counterpart. In this article, the authors provide educational video footage with accompanying text description of the senior author's (E.D.R) approach to design and elevation of the free ulnar forearm flap for the purpose of reconstructing a composite nasal defect.
