Streamlining Iliac Bone Harvest for Maxillary Reconstruction With Novel Use of Arthrex Osteochondral Autograft Transfer System.

This study introduces a novel application of the Osteochondral Autograft Transfer System (OATS) for autologous bone grafting during alveolar cleft repair. Approximately 75% of patients with cleft lip and palate have an alveolar cleft, which often necessitates secondary bone grafting from common donor sites such as the iliac crest. Traditional harvesting techniques, although effective, can be labor-intensive and increase the risk of donor site injury. Here the authors describe the use of OATS, which has primarily been used in orthopedic procedures like anterior cruciate ligament reconstruction, for the first time in alveolar cleft repair. It involves a minimally invasive, single-use transfer system for harvesting osteochondral autografts from the anterior iliac crest, and thereby reduces harvest time compared with traditional open approaches. The procedure is detailed from pre-operative evaluation through long-term follow-up and highlights the technique's benefits related to surgical time, ease of use, and maintenance of sizable autograft volumes. Similarly, the authors discuss other advantages of OATS, including its single-use and cordless nature, which is believed to contribute to a lower contamination risk and better intraoperative ergonomics.

Factors associated with late surgical correction of craniosynostosis: A decade-long review of the United States nationwide readmission database.

Late-repair craniosynostosis (LRC), defined as craniosynostosis surgery beyond 1 year of age, is often associated with increased complexity and potential complications. Our study analyzed data from the 2010-2019 Nationwide Readmissions Database to investigate patient factors related to LRC. Of 10 830 craniosynostosis repair cases, 17% were LRC. These patients were predominantly from lower-income families and had more comorbidities, indicating that socioeconomic status could be a significant contributor. LRC patients were typically treated at teaching hospitals and privately owned investment institutions. Our risk-adjusted analysis revealed that LRC patients were more likely to belong to the lowest-income quartile, receive treatment at privately owned investment hospitals, and use self-payment methods. Despite these challenges, the hospital stay duration did not significantly differ between the two groups. Interestingly, LRC patients faced a higher predicted mean total cost compared with those who had surgery before turning 1. This difference in cost did not translate to a longer length of stay, further emphasizing the complexity of managing LRC. These findings highlight the urgent need for earlier intervention in craniosynostosis cases, particularly in lower-income communities. The medical community must strive to improve early diagnosis and treatment strategies in order to mitigate the socioeconomic and health disparities observed in LRC patients.

Advances in Cleft Lip and Palate Surgery.

Cleft lip with or without cleft palate is one of the most common congenital malformations, with an average prevalence of 1 in 1000 live births. Cleft lip and/or palate is incredibly phenotypically diverse, with constant advancements and refinements in how we care for patients. This article presents an in-depth review of the latest advances and current evidence in cleft lip and palate surgery. This includes presurgical infant orthopedics, perioperative practice patterns including use of enhanced recovery after surgery (ERAS) protocols, patient-reported outcome measures, and the latest adjuncts in cheiloplasty and palatoplasty.

Incidence and Epidemiology of Traumatic Tympanic Membrane Rupture: A National Trauma Data Bank Analysis.

The incidence of traumatic tympanic membrane rupture (TTMR) has increased over recent decades. The association of certain external injury causes and bone fracture patterns with TTMR is anecdotal. It has been suggested that a diagnosis of TTMR may be missed during the acute trauma admission. The authors sought to evaluate the incidence of TTMR according to external injury cause and evaluate the association of skull fracture patterns with TTMR using a national trauma database. A cross-sectional analysis of trauma encounters was conducted using the National Trauma Data Bank (NTDB) from 2008 to 2015. Demographic and injury data were abstracted. Poisson regression was used to determine the incidence rate ratios of tympanic membrane rupture by external injury cause and logistic regression was used to estimate odds ratios (OR) of TTMR by skull fracture type. A total of 8214 patients were identified with TTMR during acute admission. The majority were on average 30 years old, 76% male, 71% White, had a mean Injury Severity Score of 14, and 42% were admitted to level I centers. The incidence rate ratio was only higher in lightning related injuries [5.262; 95% confidence interval (CI): 4.194-6.602] when using those caused by explosives as a reference. Basilar skull (OR: 12.95; 95% CI: 12.095-12.866) and cranial vault (OR: 2.938; 95% CI: 2.647-3.260) fractures were most associated with TTMR. The high incidence TTMR in association with certain external causes of injury and types of skull fractures should drive screening in the acute setting in order to increase detection and reduce morbidity from missed injuries.

Treatment of Sagittal Craniosynostosis Using Osteoplastic Parietal Craniotomy Flap With Distraction Osteogenesis: A Variation on Technique.

ABSTRACT: Late presentation sagittal craniosynostosis presents a unique challenge due to the decreased ability of the skull to repair the bony defects created by standard of care techniques. Distraction osteogenesis is a viable strategy to correct this defect in late presenting cases. The authors describe a variation in technique in which the temporalis muscle origin is retained, creating an osteoplastic bone flap with retained vascularity through the tem-poralis muscle. This may improve postoperative bony healing of bony defects in this compromised population. The authors present two patients who presented to them late with sagittal synostosis who were treated with distraction osteogenesis in which vascular continuity to the parietal bones is preserved through the temporalis muscle.

Long-Term Functional Outcomes of Trauma Patients With Facial Injuries.

BACKGROUND: Facial trauma can have long-lasting consequences on an individual's physical, mental, and social well-being. The authors sought to assess the long-term outcomes of patients with facial injuries. METHODS: This is a prospective multicenter cohort study of patients with face abbreviated injury scores ≥1 within the Functional Outcomes and Recovery after Trauma Emergencies registry. The Functional Outcomes and Recovery after Trauma Emergencies registry collects patient-reported outcomes data for patients with moderate-severe trauma 6 to 12 months after injury. Outcomes variables included general and trauma-specific quality of life, functional limitations, screening for post-traumatic stress disorder, and postdischarge healthcare utilization. RESULTS: A total of 188 patients with facial trauma were included: 69.1% had an isolated face and/or head injury and 30.9% had a face and/or head injuries as a part of polytrauma injury. After discharge, 11.7% of patients visited the emergency room, and 13.3% were re-admitted to the hospital. Additionally, 36% of patients suffered from functional limitations and 17% of patients developed post-traumatic stress disorder. A total of 34.3% patients reported that their injury scars bothered them, and 49.4% reported that their injuries were hard to deal with emotionally. CONCLUSIONS: Patients who sustain facial trauma suffer significant long-term health-related quality of life consequences stemming from their injuries.

A Yorkshire swine (Sus scrofa domesticus) model for nerve regeneration and ischemia based on the sciatic nerve and femoral artery.

Animal studies are essential to biomedical research and the cornerstone is a reproducible animal model. While there are many reports on rodent peripheral nerve injury models, a large animal model is essential to confirm the effects of nerve regeneration over the longer distances of regeneration required in humans. Swine have long been used as a large animal model for other surgical and biomedical studies. This paper represents a novel neurovascular injury model in the Sus scrofa domesticus swine (American Yorkshire pig). This paper will describe our experience and recommendations with pre-operative, operative and post-operative protocols and our refinements to produce an effective model.

Traumatic Brain Injury in Trauma Patients With Isolated Facial Fractures.

BACKGROUND: Diagnosis of traumatic brain injury (TBI), and specifically mild TBI (mTBI), is a diagnostic challenge which can delay diagnosis preventing early intervention and follow-up care. Facial fractures represent an objective surrogate marker for potential force transmission to the neural cavity. The authors' objective was to characterize the prevalence of TBI in trauma patients with isolated facial fractures stratified by injury severity. METHODS: The authors performed a retrospective cross-sectional study of the National Trauma Databank (NTDB) from 2007 to 2014 assessing a total of 1,867,761 participants identified as having a TBI and 306,785(60.2%) had an isolated facial fracture using ICD-9 codes. TBI severity was subdivided using Glasgow Coma Scale into mTBI and moderate-to-severe TBI. Logistic regression assessed odds of mTBI and moderate-to-severe TBI with different isolated facial fractures adjusted for injury severity. RESULTS: Trauma patients with isolated facial fractures of the nasal bone, mandible, malar region and maxilla, orbital floor, and alveolar and palate had a concomitant prevalence of mTBI ranging from 21.3% to 46.0% and moderate-to-severe TBI ranging from 7.3% to 18.4%. Mandibular fractures had the lowest odds of mTBI and moderate to severe TBI while alveolar and palate fractures had the highest odds of mTBI [OR3.20,95%CI (3.11-3.30)] and moderate to severe TBI [OR3.83,95%CI (3.65-4.01)]. CONCLUSIONS: Isolated facial fractures have a high prevalence of mTBI at all injury severity levels. Clinicians can use the presence of facial fractures in trauma patients to serve as clinical markers for TBI, without distracting from already existing trauma protocols and their focus on treatment of immediate life-threatening injuries raising both awareness and potential for early intervention.

Association of Vessel-Sealant Devices vs Conventional Hemostasis With Postoperative Neck Hematoma After Thyroid Operations.

Importance: Vessel-sealant devices (VSDs) have been popularized for use in thyroid operations; however, the association of their use with postoperative neck hematoma, a rare but potentially fatal complication, has not been well studied. Objective: To examine the association of VSDs vs conventional hemostasis (CH) in thyroid operations with the development of neck hematoma. Design, Setting, and Participants: This retrospective cohort study evaluated 10 903 patients in the Thyroid Procedure-Targeted Database of the National Surgical Quality Improvement Program from January 1, 2016, to December 31, 2017. One-to-one nearest-neighbor propensity score matching was conducted to adjust for differences in baseline covariates, including demographics, comorbidities, indications for thyroid procedure (goiter, Graves disease, malignant and benign thyroid nodule), and several other thyroid-specific characteristics, between the VSD and CH groups. Main Outcomes and Measures: The primary outcome was postoperative hematoma requiring intervention with open evacuation, return to the operating room, tracheostomy, additional observation, or extended length of stay. Secondary outcomes include recurrent laryngeal nerve injury, operative duration, and hospital length of stay. Results: One-to-one propensity score matching yielded 6522 patients (mean [SD] age, 52 [15] years; 8544 [78.4%] female) with 3261 in each exposure group such that distribution of observed baseline covariates was not different between groups of the same propensity score. Within the matched cohort, CH was associated with higher odds of neck hematoma compared with VSD (odds ratio, 2.33; 95% CI, 1.55-3.49; P < .001), with 34 (1.0%) hematomas in the VSD group and 78 (2.4%) in the CH group. On the basis of this analysis, the number needed to treat with a VSD to prevent 1 postoperative hematoma was 74. Secondary outcomes included longer length of hospital stay (incidence rate ratio, 1.29; 95% CI, 1.23-1.36; P < .001]) in the CH group compared with the VSD group but no difference in the odds of recurrent laryngeal nerve injury (odds ratio, 0.90; 95% CI, 0.73-1.11; P = .32) or operative duration (incidence rate ratio, 0.99; 95% CI, 0.96-1.01; P = .24). Conclusions and Relevance: Use of VSDs during thyroid operations was associated with reduced odds of neck hematoma compared with CH techniques without increasing odds of nerve injury. The results suggest that postoperative neck hematoma rates after thyroid surgery may differ based on the hemostasis technique and that these differences should be considered when developing strategies for quality improvement of postoperative outcomes.

Effectiveness of the American College of Surgeons Bleeding Control Basic Training Among Laypeople Applying Different Tourniquet Types: A Randomized Clinical Trial.

Importance: More than 500 000 laypeople in the United States have been trained in hemorrhage control, including tourniquet application, under the Stop the Bleed campaign. However, it is unclear whether after hemorrhage control training participants become proficient in a specific type of tourniquet or can also use other tourniquets effectively. Objective: To assess whether participants completing the American College of Surgeons Bleeding Control Basic (B-Con) training with Combat Application Tourniquets (CATs) can effectively apply bleeding control principles using other tourniquet types (commercial and improvised). Design, Setting, and Participants: This nonblinded, crossover, sequential randomized clinical trial with internal control assessed a volunteer sample of laypeople who attended a B-Con course at Gillette Stadium and the Longwood Medical Area in Boston, Massachusetts, for correct application of each of 5 different tourniquet types immediately after B-Con training from April 4, 2018, to October 9, 2018. The order of application varied for each participant using randomly generated permutated blocks. Interventions: Full B-Con course, including cognitive and skill sessions, that taught bleeding care, wound pressure and packing, and CAT application. Main Outcomes and Measures: Correct tourniquet application (applied pressure of ≥250 mm Hg with a 2-minute time cap) in a simulated scenario for 3 commercial tourniquets (Special Operation Forces Tactical Tourniquet, Stretch-Wrap-and-Tuck Tourniquet, and Rapid Application Tourniquet System) and improvised tourniquet compared with correct CAT application as an internal control using 4 pairwise Bonferroni-corrected comparisons with the McNemar test. Results: A total of 102 participants (50 [49.0%] male; median [interquartile range] age, 37.5 [27.0-53.0] years) were included in the study. Participants correctly applied the CAT at a significantly higher rate (92.2%) than all other commercial tourniquet types (Special Operation Forces Tactical Tourniquet, 68.6%; Stretch-Wrap-and-Tuck Tourniquet, 11.8%; Rapid Application Tourniquet System, 11.8%) and the improvised tourniquet (32.4%) (P < .001 for each pairwise comparison). When comparing tourniquets applied correctly, all tourniquet types had higher estimated blood loss, had longer application time, and applied less pressure than the CAT. Conclusions and Relevance: The B-Con principles for correct CAT application are not fully translatable to other commercial or improvised tourniquet types. This study demonstrates a disconnect between the B-Con course and tourniquet designs available for bystander first aid, potentially stemming from the lack of consensus guidelines. These results suggest that current B-Con trainees may not be prepared to care for bleeding patients as tourniquet design evolves. Trial Registration: ClinicalTrials.gov identifier: NCT03538379.

Face Transplant: Status of Current Supporting Technology to Plan and Perform the Operation and Monitor the Graft in the Postoperative Period.

Face transplant has rapidly advanced since the first operation in 2005, and to date, 40 partial or full-face transplants have been performed. The safety and efficacy of this operation are aided at all phases by supporting technologies. These include advanced imaging techniques to plan the operation, devices to monitor the flap in the immediate perioperative period, and noninvasive imaging and serum markers to monitor for acute and chronic rejection. Some of the technologies, such as those used in the immediate perioperative period, have extensive evidence supporting their use, whereas those to detect acute or chronic rejection remain investigational. The technologies of today will continue to evolve and make the operation safer with improved outcomes; however, the most significant barrier for face transplant continues to be immunologic rejection.

Effectiveness of Instructional Interventions for Hemorrhage Control Readiness for Laypersons in the Public Access and Tourniquet Training Study (PATTS): A Randomized Clinical Trial.

Importance: Several national initiatives have emerged to empower laypersons to act as immediate responders to reduce preventable deaths from uncontrolled bleeding. Point-of-care instructional interventions have been developed in response to the scalability challenges associated with in-person training. However, to our knowledge, their effectiveness for hemorrhage control has not been established. Objective: To evaluate the effectiveness of different instructional point-of-care interventions and in-person training for hemorrhage control compared with no intervention and assess skill retention 3 to 9 months after hemorrhage control training. Design, Setting, and Participants: This randomized clinical trial of 465 laypersons was conducted at a professional sports stadium in Massachusetts with capacity for 66 000 people and assessed correct tourniquet application by using different point-of-care interventions (audio kits and flashcards) and a Bleeding Control Basic (B-Con) course. Non-B-Con arms received B-Con training after initial testing (conducted from April 2017 to August 2017). Retesting for 303 participants (65%) was performed 3 to 9 months after training (October 2017 to January 2018) to evaluate B-Con retention. A logistic regression for demographic associations was performed for retention testing. Interventions: Participants were randomized into 4 arms: instructional flashcards, audio kits with embedded flashcards, B-Con, and control. All participants received B-Con training to later assess retention. Main Outcomes and Measures: Correct tourniquet application in a simulated scenario. Results: Of the 465 participants, 189 (40.7%) were women and the mean (SD) age was 46.3 (16.1) years. For correct tourniquet application, B-Con (88% correct application [n = 122]; P < .001) was superior to control (n = 104 [16%]) while instructional flashcards (n = 117 [19.6%]) and audio kit (n = 122 [23%]) groups were not. More than half of participants in point-of-care arms did not use the educational prompts as intended. Of 303 participants (65%) who were assessed 3 to 9 months after undergoing B-Con training, 165 (54.5%) could correctly apply a tourniquet. Over this period, there was no further skill decay in the adjusted model that treated time as either linear (odds ratio [OR], 0.98; 95% CI, 0.95-1.03) or quadratic (OR, 1.00; 95% CI, 1.00-1.00). The only demographic that was associated with correct application at retention was age; adults aged 18 to 35 years (n = 58; OR, 2.39; 95% CI, 1.21-4.72) and aged 35 to 55 years (n = 107; OR, 1.77; 95% CI, 1.04-3.02) were more likely to be efficacious than those older than 55 years (n = 138). Conclusions and Relevance: In-person hemorrhage control training for laypersons is currently the most efficacious means of enabling bystanders to act to control hemorrhage. Laypersons can successfully perform tourniquet application after undergoing a 1-hour course. However, only 54.5% retain this skill after 3 to 9 months, suggesting that investigating refresher training or improved point-of-care instructions is critical.

Trismus in Face Transplantation Following Ballistic Trauma.

BACKGROUND: Trismus can be a challenging consequence of ballistic trauma to the face, and has rarely been described in the setting of face transplantation. Almost half of all current face transplant recipients in the world received transplantation to restore form and function after a ballistic injury. Here we report our experience and challenges with long standing trismus after face transplantation. METHODS: We reviewed the medical records of our face transplant recipients whose indication was ballistic injury. We focused our review on trismus and assessed the pre-, peri- and postoperative planning, surgery and functional outcomes. RESULTS: Two patients received partial face transplantation, including the midface for ballistic trauma. Both patients suffered from impaired mouth opening, speech intelligibility, and oral competence. Severe scarring of the temporomandibular joint (TMJ) required intraoperative release in both patients, and additional total condylectomy on the left side 6 months posttransplant for 1 patient. Posttransplant, both patients achieved an improvement in mouth opening; however, there was persistent trismus. One year after transplantation, range of motion of the jaw had improved for both patients. Independent oral food intake was possible 1 year after surgery, although spillage of liquids and mixed consistency solids persisted. Speech intelligibility testing showed impairments in the immediate postoperative period, with improvement to over 85% for both patients at 1 year posttransplant. CONCLUSIONS: Ballistic trauma to the face and subsequent reconstructive measures can cause significant scarring and covert injuries to structures such as the TMJ, resulting in long standing trismus. Meticulous individual planning prior to interventions such as face transplantation must take these into account. We encourage intraoperative evaluation of these structures as well as peri- and postoperative treatment when necessary. Due to the nature of the primary injury, functional outcomes after face transplantation in these patients may differ substantially from those of other indications.

Bilateral Free Flap Breast Reconstruction Outcomes: Do Abdominal Scars Affect Bilateral Flaps?

BACKGROUND: The incidence of bilateral mastectomies is increasing along with the rates of breast reconstructions. A substantial number of patients will present with abdominal scars after Cesarean section, laparoscopy, laparotomy, and so on. The aim of this study was to evaluate the impact of prior abdominal scars on complication rates in abdominal bilateral free flap breast reconstruction. METHODS: All consecutive patients with autologous free flap breast reconstruction between 2007 and 2014 were eligible. The relevant demographic and clinical data were prospectively collected into a study-specific database. Complications and reoperations were prospectively registered after postoperative outpatient visits. RESULTS: Overall, 493 patients underwent abdominally based breast reconstruction during the study period: unilateral (n = 250; 50.7%) or bilateral (n = 243; 49.3%). In the bilateral group, the abdominal scar locations were Pfannenstiel (n = 73; 30.1%), midline (n = 16; 6.6%), lower oblique (n = 17; 7.0%), upper oblique (n = 5; 2.1%), and laparoscopic (n = 69; 28.4%). Four (1.7%) flap failures (including 1 converted to a pedicled transverse rectus abdominis flap) were registered, all occurring in patients from the scar group: 3 with Pfannenstiel incision and 1 patient with prior laparoscopy. Pfannenstiel scar was associated with higher risk of hematoma at the recipient site when compared with no scar group (13.7% versus 2.2%; P = 0.006). Partial flap necrosis, infection, and seroma occurred in 14 (5.9%), 8 (3.4%), and 5 (2.1%) patients, respectively, and no differences between the scar groups were identified. CONCLUSION: Surgical outcomes of bilateral reconstructions in patients with abdominal scars are generally comparable with ones in patients without prior surgery; however, some problems have been identified. These procedures might have some intraoperative considerations and often require increased operative times. Apart from the traditional preoperative computed tomography angiography, intraoperative imaging (e.g., fluorescence angiography) may be advocated in patients with abdominal scars.

Management of Rhinophyma: Outcomes Study of the Subunit Method.

BACKGROUND: Rhinophyma causes a nasal deformity and functional airway obstruction. Partial excision (eg, tangential) with secondary healing commonly removes hypertrophic soft tissues but does not improve nasal support. The subunit method for rhinophyma uses 6 nasal flaps to provide exposure for removal of rhinophymatous tissue and enhance structure. The purpose of this study was to evaluate outcomes of subunit method. METHODS: Medical records of patients with rhinophyma treated with the subunit method between 2013 and 2016 were analyzed. The technique comprises degloving the distal half of the nose by elevating 6 subunit-based flaps; debulking phymatous tissues to perichondrium; enhancing nasal support with sutures/cartilage grafts; trimming excess skin; and redraping the soft tissues. Patient age, gender, need for cartilage grafts or skin grafts, revisions, and follow-up were assessed. RESULTS: The study comprised 8 patients (6 male). Mean age was 63 years (range 34-72). All individuals had interdomal sutures for tip enhancement and 4 patients underwent cartilage grafts (alar batten) to correct external valve collapse. One patient had 2 subunits (alar) replaced with skin graft. Average follow-up was 1.6 years (range 0.2-3.7). Six patients underwent revisional procedures primarily to modify the scar between the dorsum and tip subunits. CONCLUSION: The subunit method addresses the 3 fundamental problems of the rhinophymatous nose: hypertrophic sebaceous tissues, excess skin, and destruction of support. Most patients may benefit from a minor revisional procedure to optimize the result. Individuals should be counseled that operation will likely require 2 stages.

Topical Minocycline Effectively Decontaminates and Reduces Inflammation in Infected Porcine Wounds.

BACKGROUND: Wound infection can impair postoperative healing. Topical antibiotics have potential to treat wound infection and inflammation and minimize the adverse effects associated with systemic antibiotics. METHODS: Full-thickness porcine wounds were infected with Staphylococcus aureus. Using polyurethane wound enclosure devices, wounds were treated with topical 100 µg/ml minocycline, topical 1000 µg/ml minocycline, topical saline control, or 4 mg/kg intravenous minocycline. Bacteria were quantified in wound tissue and fluid obtained over 9 hours. Immunosorbent assays were used to analyze inflammatory marker concentrations. Minocycline's effect on in vitro migration and proliferation of human keratinocytes and fibroblasts was tested using scratch assays and metabolic assays, respectively. RESULTS: After 6 hours, 100 and 1000 µg/ml topical minocycline decreased bacteria in wound tissue to 3.5 ± 0.87 and 2.9 ± 2.3 log colony-forming units/g respectively, compared to 8.3 ± 0.9 log colony-forming units/g in control wounds (p < 0.001) and 6.9 ± 0.2 log colony-forming units/g in wounds treated with 4 mg/kg intravenous minocycline (p < 0.01). After 2 hours, topical minocycline reduced concentrations of the inflammatory cytokines interleukin-1ß, interleukin-6, and tumor necrosis factor-α (p < 0.01), and inflammatory cell counts in wound tissue (p < 0.05). In noninfected wounds, topical minocycline significantly reduced interleukin-1ß, interleukin-6, and inflammatory cell counts after 4 hours (p < 0.01). Matrix metalloproteinase-9 concentrations decreased after 1-hour treatment (p < 0.05). Keratinocyte and fibroblast in vitro functions were not adversely affected by 10 µg/ml minocycline or less. CONCLUSIONS: Topical minocycline significantly reduces bacterial burden and inflammation in infected wounds compared with wounds treated with intravenous minocycline or control wounds. Minocycline also decreases local inflammation independently of its antimicrobial effect.
