Enhancing Cranio-Maxillofacial Fracture Care in Low- and Middle-Income Countries: A Systematic Review

Background: Cranio-maxillofacial (CMF) injuries represent a significant challenge in low- and middle-income countries (LMICs), exacerbated by inadequate infrastructure, resources, and training. This systematic review aims to evaluate the current strategies and solutions proposed in the literature to improve CMF fracture care in LMICs, focusing on education, patient transfer, and off-label solutions. Methods: A comprehensive literature search was conducted using PubMed/Medline from January 2000 to June 2023. Studies were selected based on the Preferred Reporting Items for Systematic Review and Meta-analysis Statement (PRISMA). Solutions were categorized into three main areas: education (digital and on-site teaching, fellowships abroad), patient transfer to specialized clinics, and off-label/non-operative solutions. Results: Twenty-three articles were included in the review, revealing a consensus on the necessity for enhanced education and training for local surgeons as the cornerstone for sustainable improvements in CMF care in LMICs. Digital platforms and on-site teaching were identified as key methods for delivering educational content. Furthermore, patient transfer to specialized national clinics and innovative off-label techniques were discussed as immediate solutions to provide quality care despite resource constraints. Conclusions: Effective CMF fracture care in LMICs requires a multifaceted approach, prioritizing the education and training of local healthcare professionals, facilitated patient transfer to specialized centers, and the adoption of off-label solutions to leverage available resources. Collaborative efforts between international organizations, local healthcare providers, and educational institutions are essential to implement these solutions effectively and improve patient outcomes in LMICs.

Epidemiological Study of Frontal Sinus Fractures: Evaluation of 16 Years of Care at the Faculty of Dentistry of Ribeirão Preto/Brazil

Purpose

Aiming to evaluate and study the epidemiological profile of frontal sinus fractures treated in the region of Ribeirão Preto-Brazil.

Methods

Sixteen years of activity in the Oral and Maxillofacial service of the Faculty of Dentistry of Ribeirão Preto/SP (FORP/USP), totaling 9,736 consultations, 4,524 with facial fractures, those diagnosed with frontal sinus fracture (113) were evaluated and selected for the study.

Results

Frontal sinus fractures accounted for 2.5% of facial fractures, the majority occurring in men (89.4%), concentrated in the age group 21-30 years old, with 52.2% of cases being caused by road traffic accidents (RTA). Associations with other facial fractures are common and appeared in 75.2% of cases. Treatment was followed either surgically, by open reduction internal fixation (52.2%) or conservatively (35.4%). Analyzing only the 28 isolated frontal sinus fractures, the most common treatment was conservative (46.4%). surgical treatment dropped to 25%. The most common postoperative complications were temporal branch paralysis and supraorbital nerve paresthesia, both occurring in 30.5% of surgical cases.

Conclusion

The frequency of frontal sinus fractures may be decreasing, but the pattern of occurrence in young men due to road traffic accidents does not seem to change, fortunately the appearance of serious complications is not common and it is usually associated with more severe trauma.

Research progress and perspective of metallic implant biomaterials for craniomaxillofacial surgeries

Craniomaxillofacial bone serves a variety of functions. However, the increasing number of cases of craniomaxillofacial bone injury and the use of selective rare implants make the treatment difficult, and the cure rate is low. If such a bone injury is not properly treated, it can lead to a slew of complications that can seriously disrupt a patient's daily life. For example, premature closure of cranial sutures or skull fractures can lead to increased intracranial pressure, which can lead to headaches, vomiting, and even brain hernia. At present, implant placement is one of the most common approaches to repair craniomaxillofacial bone injury or abnormal closure, especially with biomedical metallic implants. This review analyzes the research progress in the design and development of degradable and non-degradable metallic implants in craniomaxillofacial surgery. The mechanical properties, corrosion behaviours, as well as in vitro and in vivo performances of these materials are summarized. The challenges and future research directions of metallic biomaterials used in craniomaxillofacial surgery are also identified.

Indications and use of cone beam computed tomography in children and young individuals in a university-based dental hospital

BACKGROUND

The aim of this study was to evaluate the indications of cone beam computed tomography (CBCT) in children and young individuals in a university-based dental hospital and their association with age, gender and field of view.

METHODS

7131 CBCT scans, taken during 3-year period, were reviewed and a total of 649 pediatric patients (0-18 years) with complete request forms were included. Data related to gender, age, referring department, CBCT indications, field of view (FOV), region of interest (ROI), need for re-exposure and patients received more than one CBCT examination were recorded.

RESULTS

The mean age was 13.57 ± 3.52 years and "malocclusion and dentofacial anomaly" (28.7%) was the most common clinical indication. Facial trauma, dental trauma and supernumerary tooth in males; "malocclusion and dentofacial anomaly" and implant planning in females were recorded more frequently compared to other gender. Maxilla was the most frequently monitored ROI (35.1%) for patients. Small (≤ 10 cm) FOV was preferred in 58.1% of all patients. Large FOV was selected in the majority of patients who underwent CBCT scan for "malocclusion and dentofacial anomaly" (89.6%). The repeated scans constituted 2.3% of patients and 105 patients (16.2%) underwent multiple CBCT scans on different dates for mainly orthodontic follow-up.

CONCLUSIONS

The justification of CBCT scans was not fully compatible with current guidelines and mainly larger FOV was preferred. The number of CBCT examination in children and young individuals tends to increase.

Factors Associated with Deterioration in Quality of Life of Subjects after Maxillofacial Fractures - A Prospective Study

Introduction

Maxillofacial fractures (MFs) are quite common and are managed by oral and maxillofacial surgeons. Despite these interventions, a pre-traumatic facial profile is often not achieved with consequent social and psychologic consequences.

Materials and Methods

Patients with fractures to the middle and lower third of the face that presented within 48 hours and healthy controls (subjects without facial fracture) that were sex- and age-matched with the fracture patients were recruited into the study. World Health Organization Quality of Life - Brief Version (WHOQOL-BREF) questionnaire was used to compare the Quality of Life (QoL) values according to age, gender, educational status, employment status, marital status, site of trauma and type of fracture.

Results

Only the age of subjects was associated with deterioration in QoL after MF while other variables were not.

Discussion

Increasing age of the patients was associated with higher QoL possibly because those with age <30 years are single and unemployed and may have fear and anxiety that the fracture could affect their chances of getting married or being employed, causing reduced QoL. Psychosocial rehabilitation is very important in patients with MF, especially for the young age group.

A 10-year retrospective study on mandibular fractures in Northern Taiwan

Background/purpose

The mandible is an independent and protruding bone structure in the lower third portion of the human facial skeleton. Because of its prominent and unprotected position, the mandible is a primary site of facial trauma. Previous studies have not comprehensively discussed the association between the mandibular fractures and concomitant fractures of facial bones, the trunk, or limbs. This study analyzed the epidemiology of mandibular fractures and their correlation with concomitant fractures.

Materials and methods

The present study enrolled 118 patients with a total of 202 mandibular fracture sites during at any time from January 1, 2012, to December 31, 2021, in northern Taiwan.

Results

According to the study results, the patients between 21 and 30 years of age had the highest occurrence of trauma, and road traffic accidents (RTAs) constituted the primary cause of mandibular fractures. Fall-related injuries were significant in patients >30 years of age. By the analysis of Pearson's contingency coefficient, the number of mandibular fractures was not significantly associated with concomitant fractures of the extremities or the trunk. However, accompanying maxillary fractures can be regarded as an indication of concomitant extremity or trunk fractures in patients with mandibular fractures.

Conclusion

Three-site mandibular fractures are not necessarily accompanied by extremity and trunk fractures; however, clinicians should implement multidisciplinary examination and management in patients with mandibular fractures accompanied by maxillary fractures. Maxillary fractures can be regarded as an indication of concomitant fractures of other facial bones, the extremities, or the trunk.

Patterns of Mandibular Fractures through Human Aggression: A 10-Year Cross-Sectional Cohort Retrospective Study

The World Health Organization considers the victims of interpersonal violence to be a medical priority. In order to provide services at the highest level, we aimed to evaluate the patterns of maxillofacial fractures caused by interpersonal violence, in order to treat, counsel and guide these patients. This retrospective study was conducted in 478 patients with mandibular fractures caused by interpersonal violence over 10 years in a university clinic. The most affected were male patients (95.19%), 20-29 years of age (46.86%), under the influence of alcohol (83.26%) and without education (43.9%). The majority of mandibular fractures were displaced (89.3%) and intraorally open (64.0%). The most frequent location was the mandibular angle (34.84%). The most frequent soft tissue lesions were hematomas (45.04%) and abrasions (34.71%), being associated frequently with closed (p = 0.945/p = 0.237), displaced (p = 0.001/p = 0.002), single angle fractures (p = 0.081/p = 0.222). Educating the population and fighting alcohol consumption would decrease the occurrence of mandibular fractures through aggression. Clinical diagnosis should be made, keeping in mind that the severity of associated soft tissue lesions is directly proportional to the pattern and number of underlying fracture lines.

The Promoting Effect of a Local Pulsatile Parathyroid Hormone Delivery on Healing of the Mandibular Fracture in Rats

Parathyroid hormone (PTH) can promote bone formation and mineralization in mandibular fractures, and is systemically administered through daily injections. In this study, the local delivery of PTH using carboxymethyl chitosan/polyvinyl alcohol and alginate was investigated. Bovine serum albumin was used as a drug substitute, and the delivery system was verified to release drugs in a pulsed rhythm. After the delivery system was subcutaneously implanted in Sprague-Dawley (SD) rats, no rejection reaction was detected, indicating that it has good biocompatibility and biodegradability in vivo. Then, an SD rat model of mandibular fracture was established, and 24 rats were randomly divided into two groups. The control group was reduced and fixed with screws and a microplate, and the experimental group received pulsatile PTH release system (14 μg PTH) + screws and microplate fixation. The animals were euthanized on postoperative weeks 1-4. Observation of gross specimens, digital radiography, and hematoxylin and eosin showed that the local PTH pulsatile release system promoted osteogenesis and accelerated fracture healing. In summary, PTH can be loaded by biomaterials to locally target the fracture and stimulate bone formation. Moreover, the pulsatile PTH release system provides a potential therapeutic protocol for mandibular fracture. Impact statement Our study prepares a drug release system that could impulsively release parathyroid hormone. The system could enhance bone regeneration in rats with mandibular fracture. These data provide a foundation for future studies aimed to understand and optimize the use of bioactive molecule pulsatile delivery for bone regeneration and tissue engineering applications.

Factors affecting mortality of hospitalized facial trauma patients in Al-Ain City, United Arab Emirates

BACKGROUND

Facial injuries affect one-third of severely injured patients. These injuries have devastating long-term negative impacts on quality of life. We aimed to study the epidemiology of facial injuries and factors affecting the mortality of hospitalized facial trauma patients in Al-Ain City, United Arab Emirates.

METHODOLOGY

This is a retrospective analysis of prospectively collected data from Al-Ain Hospital Trauma Registry. All patients with facial injury who were hospitalized for more than 24 hours or who died after arrival at the hospital during the period from January 2014 to December 2017 were studied. Two sample data analysis was used to compare patients who died and those who survived. Significant factors were then entered into a backward logistic regression model to define factors affecting mortality.

RESULTS

408 patients having a mean age of 31.9 years were studied, 87.3% were males. The main mechanisms of injury were road traffic collisions (52.2%) and fall from height (11.3%). 289 (70.8%) patients had associated injuries which were mainly in the head and chest. The backward logistic regression model showed that the Glasgow Coma Scale (GCS) was the only factor that predicted mortality, p<0.0001 with the best cut-off point of 7.5, having a sensitivity of 0.972 and a specificity of 0.8. The ROC had an area under the curve of 0.924.

CONCLUSION

The majority of facial injury patients in our setting are young males who were involved in road traffic collisions or falls from height. The most important factor predicting the mortality of these patients was the low GCS. Those having a GCS of 8 and more had a better chance of survival. This information is very important when counseling patients or their relatives for facial surgery.

Quantitative analysis of soft tissue sagging after lateral midface fractures: A 10-year retrospective study

BACKGROUND

Lateral midface fractures occasionally require open reduction and internal fixation to restore function and facial symmetry. However, some patients retain facial asymmetry despite undergoing surgery due to hard tissue displacement or soft tissue sagging. This study aimed to determine the influence of soft tissue sagging on the postoperative facial symmetry.

METHODS

We examined the medical records of 590 patients who underwent planned plate removal after lateral midface or zygomatic bone fractures. After applying the inclusion and exclusion criteria, we analyzed 106 cases of lateral midface fractures for hard tissue displacement and soft tissue sagging using pre- and postoperative radiological imaging and postoperative face scanning.

RESULTS

We observed significantly larger soft tissue sagging (p &lt; 0.001) and hard tissue displacement (p = 0.006) on the fractured side than on the non-fractured side. There was no correlation between differences in the soft tissue sagging and those in the hard tissue displacement (|rho|=0). Linear regression analysis showed no statistical influence of sex or age group on the soft tissue sagging and hard tissue displacement.

CONCLUSION

Therefore, we recommend treating soft tissue sagging as a discrete aspect of midfacial fracture treatment to achieve optimal postoperative facial symmetry. From a clinical perspective, we recommend better soft tissue management during open fracture treatment than focusing mainly on the reduction of bony hard tissues.

Association between maxillofacial fractures and brain injuries in trauma patients: a cross-sectional study in the Kingdom of Saudi Arabia

Introduction

trauma is on the rise in the Kingdom of Saudi Arabia (KSA) due to rapid urbanization and motorization, posing increased risks of traumatic maxillofacial and brain injuries. Given the high morbidity and mortality associated with these injuries, this study aimed to measure the prevalence and associated factors of brain injury among head injury trauma patients.

Methods

a cross-sectional study was conducted at the King Khalid hospital and Prince Sultan Centre for Healthcare in Al-Kharj City and the Al Kharj Military Industries Corporation Hospital in Al-Kharj City in the KSA. Multivariable logistic regression modelling was performed to ascertain clinical factors associated with Traumatic Brain Injury (TBI).

Results

we included 109 participants aged median 25 and IQR (18-35) years 26.95 ± 14.73 years. Most participants were males (92.7%, n = 101) and 68% (n = 75) had Saudi nationality. About 47.7% (n = 52) had maxillofacial/skull fractures and 44% (n = 48) had TBI. Participants in the age group of 31-40 years experienced a greater risk of TBI than those in the age group of 10 or less years (aOR: 6.2, CI = 1.1p = 0.041). Participants with parietal bone fractures (aOR = 23.1, CI = 3.0 - 181.3, p = 0.003) and frontal bone fractures (aOR = 19.1, CI = 1.7 - 217.0, p = 0.017) were more likely to have TBI compared to those with other skull and facial fractures.

Conclusion

fractures of parietal and frontal bones are associated with a higher risk of TBI in the KSA. Patients with TBI following road accidents with fractures of the frontal or parietal bones, particularly those in the 31-40 age group should therefore be treated with strong suspicion of underlying traumatic brain injury.
