Abstract
Supermicrosurgery is an evolving approach in the reconstruction of head and neck (HN) and craniofacial (CF) defects. This systematic review aims to evaluate the use of supermicrosurgery for arterial or combined arterial and venous anastomoses in the reconstruction of HN and CF soft tissue defects, and the associated success, total complication, and reoperation rates. A literature search was conducted on PubMed, Dynamed, DARE, EMBASE, Cochrane, and British Medical Journal (BMJ) electronic databases (PROSPERO ID: CRD42023476825). Nine studies fulfilled the inclusion criteria with 35 patients who underwent soft tissue reconstructive procedures using supermicrosurgery. Twenty-one flaps were performed on 20 patients (57.1%) with the remaining 15 patients (42.9%) undergoing supermicrosurgical replantation. The most common pathology requiring reconstruction was HN trauma (n = 16, 45.7%) followed by malignancy (n = 15, 42.9%). The pooled success rate for supermicrosurgery was 98% (95% CI 90 to 100, p = 1.00; I2 = 0%). The cumulative complication rate across all the studies was 46% (95% CI 13 to 80, p < 0.01; I2 = 0%), and the pooled rate of reoperation was 1% (95% CI 0 to 8, p = 0.23; I2 = 24%). The use of supermicrosurgery for HN and CF soft tissue reconstruction has an overall success rate of 98%, which is commensurate with traditional microsurgery for HN reconstruction. Complication and reoperation rates are comparable to previous literature. This study confirms the feasibility of supermicrosurgery as a safe and reliable reconstructive option for HN and CF defects.

Abstract
Ballistic trauma is a serious health issue with significant costs to physical, psychosocial, economic, and societal well-being. It may be caused from firearms, explosive devices, or any other projectile forces, and is characterized by severe tissue loss and evolving tissue devitalization. This review covers mechanism, diagnosis, and management of ballistic maxillofacial trauma, specifically. Initial evaluation includes stabilization of airway, bleeding, and circulation, followed by assessment of other injuries. The overall degree of tissue damage is determined by intrinsic patient factors and extrinsic projectile factors. Management of ballistic injuries has shifted toward advocation for early operative repair with the advent of antibiotics and advanced techniques in maxillofacial reconstruction. Appropriate timing and method of reconstruction should be carefully selected on a case-by-case basis. While ballistic trauma research is limited to studies biased by institutional practices, areas for further study identified from current literature include guidelines directing timing of reconstructive surgery; thresholds for free tissue transfer; handling of retained projectiles; incidence of surgical complications; and clinical outcomes for computer-aided surgical repair of these highly destructive injuries.

Abstract
PURPOSE OF REVIEW The purpose of this article is to review the recent grafting strategies in maxillofacial trauma. RECENT FINDINGS Recent technological advancements have applications in the management of maxillofacial trauma; advancements in imaging modalities such as 3D imaging can help surgeons in both the preoperative and intraoperative periods. These may be coupled with navigational systems to further facilitate complex reconstructions. 3D printing has been used in reconstruction and 3D, 4D, and 5D bioprinting technologies continue to improve and to find new uses, and stem cells and growth factors in maxillofacial trauma are also among the most studied topics. Maxillofacial traumas have decreased in number during the COVID-19 pandemic, as more conservative approaches have been preferred in COVID pandemic conditions. SUMMARY Preoperative planning is the most important step in the reconstruction of maxillofacial trauma defects, and early bone and soft tissue reconstructions are recommended in severe maxillofacial traumas. Autogenous grafts are the gold standard in bone grafting. Nonvascularized grafts are planned according to the size, shape, and location of the defect, with vascularized bone flaps preferred in large defects, wide soft tissue defects, and contaminated defects. Alloplastic grafts or xenografts may be used if autogenous grafts are not available.

Abstract
Annual incidence of non-fatal ballistic civilian has been increasing for the last decade. The aim of the present study was to clarify the optimal reconstructive management of civilian ballistic facial injuries. A systematic review of PubMed was performed. Articles were evaluated for defect type and site, reconstructive modality, complications, and outcomes. A total of 30 articles were included. Most common region of injury was mandibular with a 46.6% incidence rate. All-cause complication rate after reconstruction was 31.0%. About 13.3% of patients developed a postoperative infection. Gunshot wounds had overall lower complication rates as compared with shotgun wounds at 9.0% and 17.0%. By region, complications for gunshot wounds were 35% and 34% for mandible and maxilla, respectively. Immediate surgical intervention with conservative serial debridement is recommended. However, for patients with pre-existing psychiatric disorders, secondary revisions should be delayed until proper psychiatric stabilization. When there is extensive loss of soft tissue in the midface, aesthetic outcomes are achieved with a latissimus dorsi or anterolateral thigh free flap. Radial forearm flap is favored for thin lining defects. Open reduction is suggested for bony-tissue stabilization. The fibula flap is recommended for bony defects >5 cm in both midface and mandible. For bony defects, <5 cm bone grafting was preferred. Delaying bone grafting does not worsen patient outcomes. Surgical treatment of ballistic facial trauma requires thorough preparation and precise planning. An algorithm that summarizes the approach to the main decision points of surgical management and reconstruction after ballistic facial trauma has been presented in this study.

Abstract
Maxillofacial defects are complex lesions stemming from various etiologies: accidental, congenital, pathological, or surgical. A bone graft may be required when the normal regenerative capacity of the bone is exceeded or insufficient. Surgeons have many options available for bone grafting including the "gold standard" autologous bone graft. However, this approach is not without drawbacks such as the morbidity associated with harvesting bone from a donor site, pain, infection, or a poor quantity and quality of bone in some patient populations. This review discusses the various bone graft substitutes used for maxillofacial and craniofacial repair: allografts, xenografts, synthetic biomaterials, and tissue-engineered substitutes. A brief overview of bone tissue engineering evolution including the use of mesenchymal stem cells is exposed, highlighting the first clinical applications of adipose-derived stem/stromal cells in craniofacial reconstruction. The importance of prevascularization strategies for bone tissue engineering is also discussed, with an emphasis on recent work describing substitutes produced using cell sheet-based technologies, including the use of thermo-responsive plates and the self-assembly approach of tissue engineering. Indeed, considering their entirely cell-based design, these natural bone-like substitutes have the potential to closely mimic the osteogenicity, osteoconductivity, osteoinduction, and osseointegration properties of autogenous bone for maxillofacial and craniofacial reconstruction.

Abstract
Surgical approaches used in accessing the facial skeleton for fracture repair are often the same as or similar to those used for cosmetic enhancement of the face. Rarely does facial trauma result in injuries that do not in some way affect the facial soft-tissue envelope either directly or as sequelae of the surgical repair. Knowledge of both skeletal and facial soft-tissue anatomy is paramount to successful clinical outcomes. Facial soft-tissue deformities can arise that require specific evaluation and management for correction. This article focuses on revision and correction of these soft-tissue-related injuries secondary to facial trauma.

Abstract
Reconstruction of maxillofacial composite defects is a technically demanding and time-demanding process. It also requires a prolonged treatment course, a team approach, and meticulous planning that is prosthetic and esthetically driven. The use of vascularized flap reconstruction, dental implants, and computer-aided technology and advances in maxillofacial prosthetics has contributed immensely toward the goal of fully reconstructing victims of large avulsive wounds. Further advances in technology, surgical training, and maxillofacial prosthodontics will undoubtedly aid in minimizing the number of surgical interventions and maximize the final functional and esthetic results of these patients.

Abstract
This case series describes craniomaxillofacial battle injuries, currently available surgical techniques, and the compromised outcomes of four service members who sustained severe craniomaxillofacial battle injuries in Iraq or Afghanistan. Demographic information, diagnostic evaluation, surgical procedures, and outcomes were collected and detailed with a follow-up of over 2 years. Reconstructive efforts with advanced, multidisciplinary, and multiple revision procedures were indicated; the full scope of conventional surgical options and resources were utilized. Patients experienced surgical complications, including postoperative wound dehiscence, infection, flap failure, inadequate mandibular healing, and failure of fixation. These complications required multiple revisions and salvage interventions. In addition, facial burns complicated reconstructive efforts by delaying treatment, decreasing surgical options, and increasing procedural numbers. All patients, despite multiple surgeries, continue to have functional and aesthetic deficits as a result of their injuries. Currently, no conventional treatments are available to satisfactorily reconstruct the face severely ravaged by explosive devices to an acceptable level, much less to natural form and function.

Abstract
Microvascular free tissue transfer (FTT) is an increasingly used method of reconstruction for traumatic defects of the head and neck. We describe the immediate management, FTT reconstruction techniques, and outcomes of 6 individuals who sustained maxillofacial gunshot trauma and were treated at a single tertiary-care level I trauma center. All 6 patients were white men with a mean age of 33 years. The mandible, nose, and orbital contents were the most frequently affected critical structures. All patients initially underwent primary wound debridement and tracheostomy, with concurrent maxillomandibular wire fixation and/or midface or mandible plate fixation in 5 patients. The mean time from injury to definitive FTT was 38 days. Five patients underwent fibula osteocutaneous FTT and 1 underwent radial forearm fasciocutaneous FTT. One patient also underwent concurrent local tissue rearrangement and pedicled flap surgery for nasal reconstruction. The mean hospital length of stay after FTT was 6 days. All FTT survived without necrosis. Oral incompetence and poor cosmesis from undesirable scarring patterns were the most common long-term complications. In summary, successful reconstruction of head and neck defects caused by gunshot trauma begins with airway stabilization, wound management, and bony fracture reduction and fixation. Definitive microvascular FTT is a useful method of repairing traumatic head and neck defects, although long-term functional and cosmetic complications may still occur.

Abstract
UNLABELLED This study analyses the US Army Joint Theatre Trauma Registry database for craniomaxillofacial (CMF) battle injuries (BI) experienced by US Service Members in Iraq/Afghanistan conflict to describe type, distribution and mechanism of injury. METHODS AND MATERIALS Joint Theatre Trauma Registry was queried from 19 October 2001 to 12 December 2007 for CMF BI entered in the database using ICD-9 codes; the data was compiled for BI soldiers. RESULTS We have identified 7770 BI. About 26% had CMF BI. There were 4783 CMF BI among the 2014 BI (2.4 injuries per soldier). Majority of CMF BI were male (98%). Average age was 26 years. CMF BI by branch of service was Army 72%, Marines 24%, Navy 2% and Air Force 1%. Penetrating soft tissue injuries and fractures were 58% and 27%, respectively; 76% of fractures were open and 24% of soft tissue injuries were noted as complicated. Frequency of facial fractures was mandible 36%, maxilla/zygoma 19%, nose 14%, and orbit 11%. Remaining 20% not otherwise specified. Primary mechanism of injury was explosive devices (84%). CONCLUSIONS Twenty-six per cent of all BI were to CMF area. CMF BI account for a disproportionate number of injuries observed in Iraq and Afghanistan compared with the previous American Wars. Mechanism of CMF BI involves explosive devices 84%.
