Background and Clinical Significance: Pneumocephalus, an accumulation of air within the cranial cavity, typically arises from trauma or iatrogenic causes. However, spontaneous occurrences of this are rare and linked to various pathologies affecting the paranasal sinuses, the ear, or the skull base. The impact of air travel on individuals with pneumocephalus remains uncertain despite ongoing research. We report a unique case of spontaneous tension pneumocephalus attributed to a frontal sinus osteoma during air travel. Case Presentation: A 55-year-old man presented with headache and dizziness, initiated during a nine-hour international flight two weeks prior. The symptoms abated after landing but recurred on his return flight, accompanied by confusion the following day. A neurological examination revealed no deficits. CT and MRI scans indicated the presence of intraparenchymal air collection in the right frontal lobe, attributed to a frontal sinus osteoma causing a dural tear. Surgical intervention included duroplasty and osteoma removal, with postoperative recovery free of complications. Conclusions: Frontal sinus osteoma-induced tension pneumocephalus is exceedingly rare, with only limited cases reported in the literature. This case shows that air travel may exacerbate intracranial gas dynamics that lead to development of tension pneumocephalus with a potentially fatal outcome for patients. Full article

Traumatic direct type carotid cavernous fistula (CCF) is an acquired arteriovenous shunt between the carotid artery and the cavernous sinus post severe craniofacial trauma or iatrogenic injury. We reported a 46-year-old woman who had developed a traumatic direct type CCF after severe head trauma with a skull base fracture and brain contusion hemorrhage. The clinical manifestations of the patient included pulsatile exophthalmos, proptosis, bruits, chemosis, and a decline in consciousness. Magnetic resonance imaging (MRI) revealed engorgement of the right superior ophthalmic vein (SOV), perifocal cerebral edema in the right frontal–temporal cortex, right basal ganglia, and brain stem. Digital subtraction angiography (DSA) disclosed a direct type high-flow CCF with an aggressive cortical venous reflux drainage pattern, which was attributed to Barrow type A and Thomas classification type 5. After partial treatment by transvenous coil embolization for the CCF, the residual high-flow fistula with aggressive venous drainage had an unusual rapid spontaneous resolution in a brief period. Therefore, it is strongly recommended to meticulously monitor the clinical conditions of patients and perform brain MRI and DSA at short intervals to determine the treatment strategy for residual CCF after partial endovascular treatment.

Study Design: Retrospective cohort study. Objective: Frontal sinus fractures (FSFs) can lead to a range of clinical challenges, including facial deformity, impaired facial sensation, cerebrospinal fluid (CSF) leakage, sinus drainage impairment, chronic sinus pain and mucocele formation. The optimal management approach, whether surgical or conservative, remains a topic of ongoing discussion. The aim of this study was to evaluate and compare the functional and esthetic outcomes of patients with surgically and conservatively treated FSFs. Methods: In this retrospective study, patients treated for FSFs at the Karolinska university hospital 2004 to 2020 were identified in hospital records and invited to participate in a long-term follow-up. Sequelae and satisfaction with the esthetic result were assessed trough questionnaires and physical examinations. Results: A total of 93 patients were included in the study, with 49 presenting isolated anterior wall fractures and 44 presenting combined anterior and posterior wall fractures. Surgical intervention was performed in 45 cases, while 48 were managed conservatively. Among patients with moderate anterior wall fractures (4–6 mm dislocation), 80% of surgically treated patients compared to 100% of conservatively treated patients expressed satisfactionwith their cosmetic outcomes at follow-up (p = 0.03). In conservatively treated patients with a forehead impression, the anterior wall fracture dislocation ranged from 5.3 to 6.0 mm (p < 0.0001). Approximately 50% of surgically treated patients vs 15% of conservatively treated patients developed impaired forehead sensation at follow-up (p = 0.03). Thirty-six percent of surgically treated patients reported dissatisfaction with surgery-related scarring, particularly those who underwent surgery via laceration or bicoronal incision. Conclusions: This study suggests that anterior FSFs with a dislocation of 5 mm or less can be effectively managed conservatively with high patient satisfaction, low risk of long-term forehead sensation impairment and without potential development of forehead impression. Bicoronal incision or incision via a laceration may be associated with esthetic dissatisfaction and late sequelae such as alopecia. Full article

Injuries to humans caused by wild animals, particularly bears, are rarely mentioned in the literature. Such injuries are frequent in Siberia, which is a territory surrounded by dense forests inhabited by brown bears. In the last 4 months alone (September–December 2023), four bear attacks on humans were registered in Khakassia, Russia. This article presents a clinical case of rehabilitating a patient after a bear attack, who suffered multiple fragmentary fractures of the facial skeleton with displaced bone fragments, subcutaneous emphysema of the soft tissues of the face, damage to the parietal and right occipital regions and paranasal sinus hemorrhage on the left side. The nature of the injuries was enhanced by trauma to the upper extremity caused by the patient defending himself against the animal. In addition to the damage to his face, the bear tried to open his cranium, as evidenced by four furrows caused by its canines, including two each on the frontal and occipital bones of the skull. The patient’s complex treatment included both maxillofacial and reconstructive surgeries, and outpatient treatment involved the formation of normotrophic scars using a neodymium laser and injections of a heterogeneous composition consisting of microparticles of “crosslinked” collagen of animal origin placed in a gel identical to the natural extracellular matrix.

Study Design: This is anobservational, retrospective, analytical study. Objective: The aim was todetermine a statistical basis for a future line of research based on the epidemiology of a center located in a developing country, as well as defining indirect mortality predictors. Methods: Clinical files were reviewed based on diagnosis of Traumatic Brain Injury (TBI), according to the International Classification of Diseases 10th Revision (ICD-10). Sociodemographic variables as well as treatment modality of the condition during hospitalization was recorded. The patient sample was divided into two groups. Student’s t-test was performed in variables with normal distribution and Chi-square test in independent random variables with standard normal distribution. For correlations, Pearson’s correlation coefficient was used, taking the p-value < 0.05 as statistically significant. Results: A total of 150 participantswere included in this study, fromwhich 125 weremale (83.3%). The average age was 28.58 ± 16.55 years. The median hospitalization time was 9 days. Forty-five patients (30%) were treated conservatively. Fifteen patients died during hospitalization. The factors considered as predictors of mortality in the general population corresponded to Motor Vehicle Accident, Frontonasal Duct Obstruction, Neuroinfection, Glasgow Coma Scale (GCS) at admission, as well asGCS at discharge. In the patients who underwent surgery, predictors of mortality corresponded to Motor Vehicle Accident, Bilateral Frontal Craniotomy, Surgical Bleeding > 475 cc, Neuroinfection, as well as GCS at admission and discharge. Conclusions: The creation of adequate diagnostic and therapeutic algorithms in traumatic brain injury management is needed, especially in developing countries. More specific studies are needed, particularly analytical and multicentric studies, which may allow the development of these algorithms. Full article

Study Design: This is an experiential article based on the past 6 years experience of providing facial gender confirmation surgery (fGAS) at an academic medical center. Objective: While trainees are getting increasing exposure to aspects of facial gender affirming surgery (fGAS), the gap between trained providers and patients who can access care is currently still widening. A handful of fellowships across the country have emerged that include fGAS in their curriculum, but it will take another decade before the principles of affirming care and surgeries are systematically taught. Fortunately, the surgical principles and techniques required to perform fGAS are part of the skill set of any specialty surgeon trained in adult craniofacial trauma and esthetic facial surgery/rhinoplasty. It is the aim of this article to provide directly applicable knowledge with the goal to assist surgeons who consider offering fGAS in flattening the learning curve and hopefully contribute to increasing the quality of care provided for the transgender and gender diverse population. We hope to provide the reader with a very tangible article with the aims to (1) provide a simple systematic framework for an affirming consultation and preoperative assessment and (2) provide translatable surgical pearls and pitfalls for forehead feminization and gonial angle resection. The frontal sinus set back and gonial angle resection in our opinion are the most unique aspect to fGAS as rhinoplasty, genioplasty and other associated procedures (e.g., fat grafting) follow well established principles. We hope that the value of this article lies in the translatability of the presented principle to any practice setting without the need for VSP, special surgical instruments or technology beyond basic craniofacial tools. Methods: This is an experiential article based on the senior authors 6 year experience offering fGAS in an academic setting. The article is structured to outline both pearls and pittfalls and is supplemented by photographs and a surgical video. Results: A total of 19 pearls and pitfalls are outlined in the article. Conclusions: Facial gender affirming surgery mostly follows established craniofacial and esthetic surgery principles. Forehead feminization and gonial angle feminization are the 2 components that diverge most from established surgical techniques and this article hopefully provides guidance to shorten the learning curve of surgeons.

Study Design: Retrospective chart review. Objective: The objective of this study was to determine if proceeding with feminization frontal cranioplasty without preoperative imaging adversely affected patient outcomes. Methods: This study retrospectively reviewed all patients undergoing frontal cranioplasty for facial feminization at a single tertiary care center between 2013 and 2019. All procedures were performed by a single surgeon (JS), who operated at multiple sites. The site selected is where the majority of these procedures were performed during this time. Type of cranioplasty (I vs III) was recorded. Primary outcomes included postoperative cerebrospinal fluid (CSF) leak, entering the cranium, or dural exposure or injury. Results: 422 subjects underwent cranioplasty for facial feminization between 2013 and 2019. No preoperative imaging was performed. Zero patients had CSF leak. 334 subjects (79%) had type III cranioplasty, while the remaining 88 subjects (21%) had type I cranioplasty. No subjects had documented episodes of dural injury, or postoperative brain or cranial concerns. Conclusions: This study demonstrates that frontal cranioplasty for facial feminization does not require routine preoperative imaging. The authors recommend preoperative imaging for patients with a history of congenital cranial abnormality, prior significant head trauma affecting the frontal bone, and in some cases where the patient has had prior surgery or a history of sinus disease or extensive polyposis. Routine preoperative computed tomography is therefore not indicated for patients undergoing feminizing cranioplasty. Full article

Study Design: Case series. Objective: This retrospective review of frontal sinus fractures aims to describe our current experience managing these fractures at an urban level I trauma center. Methods: An institutional database of 2081 patients who presented with maxillofacial fractures on computed tomography face/sinus in 2019 was queried for all patients with traumatic frontal sinus fractures. Demographics, trauma-related history, management approach, and follow-up data were collected and analyzed. Results: Sixty-three (7.3%) patients had at least one fracture involving the frontal sinus. The most common etiologies were assaults, falls, and motor vehicle accidents. Surgical repair was performed in 26.8% of patients with frontal sinus fractures, and the other 73.2% were observed. Fractures that were displaced, comminuted, obstructive of the frontal sinus outflow tract, or associated with a dural tear or cerebrospinal fluid leak were more likely to be operative. Conclusions: The majority of frontal sinus fractures in this study were treated with observation. Despite advances in transnasal endoscopic approaches, many surgeons still rely on open approaches to repair frontal sinus fractures. Full article

Frontal bone trauma has an increasing incidence and prevalence due to the wide-scale use of personal mobility devices such as motorcycles, electric bicycles, and scooters. Usually, the patients are involved in high-velocity accidents and the resulting lesions could be life-threatening. Moreover, there are immediate and long-term aesthetic and functional deficits resulting from such pathology. The immediate complications range from local infections in the frontal sinus to infections propagating inside the central nervous system, or the presence of cerebrospinal fluid leaks and vision impairment. We review current trends and available guidelines regarding the management of cases with frontal bone trauma. Treatment options taken into consideration are a conservative attitude towards minor lesions or aggressive surgical management of complex fractures involving the anterior and posterior frontal sinus walls. We illustrate and propose different approaches in the management of cases with long-term complications after frontal bone trauma. The team attending to these patients should unite otorhinolaryngologists, neurosurgeons, ophthalmologists, and maxillofacial surgeons. Take-home message: Only such complex interdisciplinary teams of trained specialists can provide a higher standard of care for complex trauma cases and limit the possible exposure to further legal actions or even malpractice.

Naso-orbito-ethmoid (NOE) fractures associated with anterior and posterior frontal sinus wall fractures are among the most challenging cranio-maxillofacial injuries. These represent a major emergency, having a potentially severe clinical picture, with intracranial hemorrhage, cerebrospinal fluid (CSF) leak, meningeal lesions, pneumocephalus, contusion or laceration of the brain matter, coma, and in some cases death. In this article, we present the case of a 30-year-old patient with the diagnosis of NOE fracture associated with bilateral anterior and posterior frontal sinus wall fractures caused by a horse kick, with a fulminant post-traumatic alteration of the neurological status and major impairment of the midface bone architecture. Despite the severity and complexity of the case, early initiation of correct treatment both in terms of intensive care and cranio-maxillofacial surgery led to the successful rehabilitation of the neurological status, as well as to the reconstruction and redimensioning of midface architecture and, not least, to the restoration of the patient’s physiognomy.

The etiology of fractures of the maxillofacial skeleton varies among studies, with motor vehicle accidents and assaults oftentimes the most common. The number of males outnumbers females throughout most studies. Fractures of the zygoma, orbit, and mandible are usually cited as most common fracture types. This study examines a single center's experience with regards to etiology and distribution of fractures. A retrospective review of all radiologically confirmed facial fractures in a level 1 trauma center in an urban environment was performed for the years 2000 to 2012. Patient demographics, etiology of injury, and location of fractures were collected. During this time period, 2998 patients were identified as having sustained a fracture of the facial skeleton. The average age was 36.9 years, with a strong male predominance (81.5%). The most common etiologies of injury were assault (44.9%) and motor vehicle accidents (14.9%). Throughout the study period, the number of fractures as a result of assault remained relatively constant, whereas the number as a result of motor vehicle accidents decreased slightly. The most common fracture observed was of the orbit, followed by mandible, nasal bones, zygoma, and frontal sinus. Patients sustaining a fracture as a result of assault were more likely to have a mandible fracture. Patients in motor vehicle accidents were more likely to suffer fractures of the maxilla, orbit, and frontal sinus. Mandible fractures are more common in cases of assault. Motor vehicle accidents convey a large force, which, when directed at the craniofacial skeleton, can cause a variety of fracture patterns. The decreasing number of fractures as a result of motor vehicle accidents may represent improved safety devices such as airbags. Full article

Efficacy of prophylactic antibiotics in craniofacial fracture management is controversial. The purpose of this study was to compare evidence-based literature recommendations regarding antibiotic prophylaxis in facial fracture management with expert-based practice. A systematic review of the literature was performed to identify published studies evaluating pre-, peri-, and postoperative efficacy of antibiotics in facial fracture management by facial third. Study level of evidence was assessed according to the American Society of Plastic Surgery criteria, and graded practice recommendations were made based on these assessments. Expert opinions were garnered during the Advanced Orbital Surgery Symposium in the form of surveys evaluating senior surgeon clinical antibiotic prescribing practices by time point and facial third. A total of 44 studies addressing antibiotic prophylaxis and facial fracture management were identified. Overall, studies were of poor quality, precluding formal quantitative analysis. Studies supported the use of perioperative antibiotics in all facial thirds, and preoperative antibiotics in comminuted mandible fractures. Postoperative antibiotics were not supported in any facial third. Survey respondents (n = 17) cumulatively reported their antibiotic prescribing practices over 286 practice years and 24,012 facial fracture cases. Percentages of prescribers administering pre-, intra-, and postoperative antibiotics, respectively, by facial third were as follows: upper face 47.1, 94.1, 70.6; midface 47.1, 100, 70.6%; and mandible 68.8, 94.1, 64.7%. Preoperative but not postoperative antibiotic use is recommended for comminuted mandible fractures. Frequent use of pre- and postoperative antibiotics in upper and midface fractures is not supported by literature recommendations, but with low-level evidence. Higher level studies may better guide clinical antibiotic prescribing practices. Full article

This study evaluated postoperative results of 8 cases of frontal sinus fractures treated by frontal sinus obliteration with autogenous bone from the anterior iliac crest. Patients and methods: The medical charts of patients sequentially treated for frontal sinus fractures by obliteration with autogenous cancellous iliac crest bone in the Oral and Maxillofacial Surgery Division of this institution were reviewed. From those, eight had complete records and adequately described long-term follow-up. All were operated by the same surgical team. Those patients were recalled and independently evaluated by 2 examiners. Radiographs and/or CT scans were available for this evaluation. Associated fractures and complications were noted. The average postoperative follow-up was 7 years, ranging from 3 to 16 years. The main complication was infection. Four patients (50%) had uneventful long-term follow-ups and four (50%) experienced complications requiring reoperation. Based on the studied sample studied the authors conclude that the obliteration with autogenous bone presented a high percentage of complications in this series. Full article

Management of fractures involving the frontal sinus seems to be more complex than merely obtaining an ideal reduction of the bony injuries. Multiple articles on the management of these fractures suggest that a great deal of controversy persists despite many years of surgical experience. The question posed in this article is whether or not the advent of endoscopic approaches has changed or should change the approaches/algorithms used in the management of these challenging fractures. It is the conclusion of these authors that endoscopic techniques can indeed allow us to change the algorithm for management of frontal sinus trauma. New algorithms are proposed that should provide guidance to craniomaxillofacial surgeons treating these injuries in the endoscopic age. Full article

The purpose of this article is to present the case of maxillofacial trauma patient with maxillary sinus fracture diagnosed with cone-beam computed tomography (CBCT) and to explore the applications of this technique in evaluating the maxillofacial region. A 23-year-old male patient attempted to our clinic who had an injury at midface with complaints of swelling, numbness. The patient was examined before in emergency center but any diagnosis was made about the maxillofacial trauma. The patient re-examined clinically and radiographically. A fracture on the frontal wall of maxillary sinus is determined with the aid of CBCT. The patient consulted with the department of maxillofacial surgery and it is decided that any surgical treatment was not necessary. The emerging technique CBCT would not be the primary choice of imaging maxillofacial trauma. Nevertheless, when advantages considered this imaging procedure could be the modality of choice according to the case. Full article
