Abstract
Frontal fractures can be associated with major facial defects and present, in some cases, a challenge in bone reconstruction. Due to this challenge, this work aims to describe the use of the posterior table of the frontal sinus as a fragment to reconstruct this region. However, this technique is reserved for cases where the posterior table will be removed due to its fracture and is more intact than the anterior table of the frontal sinus.

Abstract
Brow position, hairline shape, and forehead projection may confer cis-feminine identity, and facial feminization surgery (FFS) can improve gender dysphoria among transfeminine patients. Depending on the Ousterhout classification, burring, osteotomy, anterior frontal sinus setback, and augmentation, with subsequent fixation via metal or bioabsorbable plates, can address forehead projection. However, titanium mesh, often used in frontal sinus fracture repair, has not been described for forehead contouring in FFS. The purpose of this study was to study clinical outcomes associated with the use of titanium mesh for the stabilization of bone following anterior frontal sinus setback. A retrospective cohort study of trans-female and nonbinary patients undergoing primary FFS by our senior author between January 2021 and February 2023 was performed. Variables collected include demographics, Ousterhout classification, operative details, complications, and follow-up duration. Patients with prior FFS or facial trauma were excluded. Data were analyzed using SPSS, (IBM, Armonk, NY). Forty-three transfeminine patients were included for analysis. The cohort had an average age of 33.0±8.7 years and a median follow-up time of 3.0 months (IQR = 1.0-7.0). Among our cohort, 26 patients (60.5%) received titanium mesh and 17 patients (39.5%) underwent burring only for forehead contouring. There were no reported complications (ie, infection, hardware extrusion, or mucocele formation) or a need for forehead revisions among the entire cohort regardless of the frontal sinus reconstruction material utilized. Clinical outcomes were favorable among patients receiving titanium mesh anterior table fixation during FFS. Titanium mesh can be considered as an additional technique for frontal bossing reduction and anterior table fixation in FFS.

Abstract
Background: Frontal sinus fractures are relatively rare. Their surgical management significantly differs depending on whether the posterior wall is invaded and the clinical features vary. A bicoronal incision or endoscopic approach can be used. However, the minimally invasive approach has been attracting attention, leading us to introduce a simple and effective surgical method using multiple-threaded Kirschner wires.Methods: All patients had isolated anterior wall fractures without nasofrontal duct impairment. The depth from the skin to the posterior wall was measured using computed tomography to prevent injury. The edge of the bone segment on the skin was marked, a threaded Kirschner wire was inserted into the center of the bone segment, and multiple Kirschner wires were gently reduced simultaneously.Results: Surgery was performed on 11 patients. Among them, seven patients required additional support for appropriate fracture reduction. Therefore, a periosteal elevator was used as an adjunct through a small sub-brow incision because the reduction was incomplete with the Kirschner wire alone. The reduction results were confirmed using facial bone computed tomography 1 to 3 days postoperatively. The follow-up period was 3 to 12 months.Conclusion: The patients had no complications and were satisfied with the surgical results. Here we demonstrated an easy and successful procedure to reduce a pure anterior wall frontal sinus fracture via non-invasive threaded Kirschner wire reduction.

Abstract
OBJECTIVE To describe the use of temporal fascia free grafts to treat dorsal open comminuted frontal sinus and nasal fractures. ANIMAL One Belgian shepherd dog. STUDY DESIGN Case report METHODS: A 5-year-old spayed female Belgian shepherd was admitted with severe facial deformation due to trauma. A deep, 3 cm wide wound was present between the nose and the frontal sinus. No abnormalities were detected on neurological examination. On computed tomographic examination, comminuted open fractures of the frontal and nasal bones were associated with a severe depression of the dorsal wall and presence of bone fragments in the sinus cavities. Bone fragments were apposed with polydioxanone monofilament suture. Bilateral temporal fascia grafts were placed over the bone fragments. RESULTS The integrity of the frontal and nasal cavities, and the facial profile of the dog were restored. No short-term or long-term complications were observed after 4 months follow up. CONCLUSION The innovative combination of suture apposition of bone fragments and a temporal fascia free graft resulted in very satisfying long-term outcomes in a dog with open sinus and nasal bone fractures.

Abstract
Multiply fragmented fractures of the maxillofacial region are difficult to fix with traditional miniplate osteosynthesis because of the extremely small size of fragments, complex three-dimensional anatomy, thin bone unable to hold screws and multidirectional pull of muscles. We intend to present a technical note on a case series of extremely comminuted midfacial fractures reconstructed with stock Titanium mesh, cut to shape and used to mold the small fragmented segments into the shape of the facial bones. Severe fragmentation of midface leads to facial hollowing, tissue prolapse and asymmetry even after major facial buttresses are fixed and reconstructed. Simple stock Titanium mesh can be used to reconstruct these severe fragmentations of thin bones of the midface as shown in the series and avoid late and unsightly complications.

Abstract
INTRODUCTION Frontal bone fractures show a low frequency of occurrence of about 5% to 15% of all maxillofacial fractures occurring due to high-velocity injuries such as in the case of road traffic accidents, sporting events, assaults. Successful surgical management revolves around the concept of minimizing cosmetic deformity, maintaining normal sinus function, avoidance of short and long-term complications. In this article, the authors report a case series of 24 cases of frontal bone fracture treated with various treatment modalities. MATERIALS AND METHODS A total of 24 cases of frontal bone fracture admitted to our facility were treated accordingly and the subsequent follow up data were collected and compiled to be included in this study. RESULTS In our study, 83.33% cases showed isolated anterior table fractures, 8.3% cases with combined anterior and posterior table fractures. 40% cases managed conservatively, 41.6% with titanium mini plates, 12.5% cases with titanium mesh and 4% with cranialisation with fat obliteration. CONCLUSION Our treatment decisions were based upon the extent and severity of the injuries which aided in tailoring the treatment modality. Thereby, curbing the long-term complications which could be foreseen and hence, a better functional outcome was achieved.

Abstract
Objective Analysis of our traumatic brain injury data, reviewing current literatures and assessing planning valuable decision making in frontal sinus fracture for young neurosurgeons. Methods Hospital data base for head trauma was retrieved after board permission for retrospective analysis of cases admitted from 2010-2020. Patients with frontal sinus fractures and head trauma were identified according to a flow chart. Variables of the study included patients' demographics, mechanism of injury, incidence of cerebrospinal fluid (CSF) leakage, types of associated injuries, imaging findings and operative techniques. Results Three-hundred eighty two patients were eligible to be screened in our study and represented the sample size under investigations in the following sections, 206 (53.9%) of patients were treated conservatively while 176 patients (46.1%) were identified as having an indication for surgical intervention. Eighty-four percent of patients were males. The mean age was 36.2±9.4 years (14-86 years). Depressed skull fracture was commonly associated injury (17.61%). Leakage of CSF was found in 32.95% of patients. Conclusion Frontal sinus fracture is not an easy scenario. It harbors many proportions and deliver many varieties in which, deep understanding of anatomy, naso-frontal outflow tract status, CSF leakage and neurological injury are of important points in decision. Our institutional algorithm provide rapid, accessible and applicable treatment protocol for resident and young neurosurgeons which minimizes consultations of other specialties.

Abstract
Critical-sized bone defect repair remains a substantial challenge in clinical settings and requires bone grafts or bone substitute materials. However, existing biomaterials often do not meet the clinical requirements of structural support, osteoinductive property, and controllable biodegradability. To treat large-scale bone defects, the development of three-dimensional (3D) porous scaffolds has received considerable focus within bone engineering. A variety of biomaterials and manufacturing methods, including 3D printing, have emerged to fabricate patient-specific bioactive scaffolds that possess controlled micro-architectures for bridging bone defects in complex configurations. During the last decade, with the development of the 3D printing industry, a large number of tissue-engineered scaffolds have been created for preclinical and clinical applications using novel materials and innovative technologies. Thus, this review provides a brief overview of current progress in existing biomaterials and tissue engineering scaffolds prepared by 3D printing technologies, with an emphasis on the material selection, scaffold design optimization, and their preclinical and clinical applications in the repair of critical-sized bone defects. Furthermore, it will elaborate on the current limitations and potential future prospects of 3D printing technology. STATEMENT OF SIGNIFICANCE: 3D printing has emerged as a critical fabrication process for bone engineering due to its ability to control bulk geometry and internal structure of tissue scaffolds. The advancement of bioprinting methods and compatible ink materials for bone engineering have been a major focus to develop optimal 3D scaffolds for bone defect repair. Achieving a successful balance of cellular function, cellular viability, and mechanical integrity under load-bearing conditions is critical. Hybridization of natural and synthetic polymer-based materials is a promising approach to create novel tissue engineered scaffolds that combines the advantages of both materials and meets various requirements, including biological activity, mechanical strength, easy fabrication and controllable degradation. 3D printing is linked to the future of bone grafts to create on-demand patient-specific scaffolds.

Abstract
PURPOSE OF REVIEW The purpose of this manuscript is to review the current literature regarding the management of frontal sinus fractures and offer the authors opinion on the current management of these traumatic injuries. We evaluate recently proposed management algorithms as well as novel surgical approaches reported within the last few years. RECENT FINDINGS Patient selection for sinus sparing treatment modalities is balanced between fracture severity, involved structures, and reliable patient surveillance. Minimally invasive, aesthetically favorable approaches grow in diversity for anterior table fractures. For fractures of the posterior sinus wall and nasofrontal outflow tract, the literature focuses on sinus sparing surgery, as well as better defining the patients in which obliteration and/or cranialization is appropriate. SUMMARY Lack of large patient cohorts and follow-up limits generalizability of frontal sinus fracture research, and the ability to develop national guidelines of management. Evidence-based literature shows growing support for conservative management and sinus preservation. Improvements in frontal sinus fracture classification schemes, surgical technique, and patient selection direct this treatment paradigm shift.

Abstract
Anterior table frontal sinus fractures can result in aesthetically displeasing contour deformities. Acute anterior table frontal sinus fractures that are depressed may be reduced with an open, closed, or endoscope-assisted approach. Delayed contour deformity camouflage can be achieved using bone grafts, titanium meshes, methyl methacrylate, hydroxyapatite cement, and polyether ether ketone implants. The selection of surgical approach to repair a frontal sinus contour deformity depends on the fracture severity, chronicity, complexity, patient comorbidities, and surgeon preference and experience. Advancement in endoscopic technology and expertise has created a paradigm shift toward a less invasive approach to the frontal region, with considerably less morbidity than conventional open techniques.
