Trend and Demographic Characteristics of Maxillofacial Fractures in Level I Trauma Center

Orbital fractures treated in a university hospital of southern Italy: epidemiology, outcomes and prognostic factors resulting from 538 retrospectively analyzed cases

PURPOSE

Orbital fractures are common injuries and represent an interesting chapter in maxillofacial surgery. This retrospective study analyses data collected from 528 patients surgically treated at the University Hospital "Magna Graecia", Catanzaro, Italy, from 1st January 2007 to 31st January 2021.

METHODS

The inclusion criteria were a diagnosis of orbital bone fracture, complete clinical and radiological records, and a minimum follow-up of 12 months. We analyzed gender, age, etiology, fracture type, treatment, timing of repair, and associated complications.

RESULTS

The most frequent cause of trauma was road accidents (37.88%), followed by domestic accidents (25.95%). The manifestation of diplopia (72.35%), infraorbital nerve hypoesthesia (53.41%), extrinsic eye movement limitation (51.70%), and enophthalmos (41.29%), determined the indication for surgery. Our trauma team preferred the sub-eyelid approach (79.36%). The study shows a statistical significance in the correlation between the severity of the herniation of the lower rectus muscle and the presence of preoperative diplopia (p-value = 0.00416); We found the same statistical significance for the post-postoperative diplopia (p-value = 0.00385). Patients treated two weeks after the trauma show a higher rate of diplopia and a greater limitation of long-term post-operative eye movements than those treated within two weeks (diplopia 23.08% vs. 15.56%; eye movements limitation 13.33% vs. 7.69%). Early surgical treatment (> 14 days) reduces the likelihood of functional and structural damage to the lower rectus muscle.

CONCLUSION

Our data will support future maxillofacial traumatology studies, and the education and prevention measures taken will reduce the incidence of orbital trauma.

Assessment of relationships between condylar fracture pattern and mandibular third molar position by panoramic radiography and computed tomography: A retrospective comparative study

BACKGROUND/AIM

Although previous studies have revealed the influence of the mandibular third molar (M3) on mandibular condylar fracture risk and that the presence of M3 could result in different incidences of condylar and angle fractures, there have been no analyses of the influence of M3 on fracture patterns. Moreover, evaluations of M3 position using panoramic radiography have shown insufficient accuracy. This study investigated the relationship between condylar fracture patterns and M3 position using panoramic radiography and computed tomography.

MATERIALS AND METHODS

This retrospective study included 280 patients with unilateral mandibular condylar fractures and ipsilateral M3 admitted to West China Hospital of Stomatology between January 2016 and June 2022. Patient medical records, panoramic radiographs, and computed tomography images were collected. The vertical and horizontal positions of M3 were classified using the Pell and Gregory system. M3 angulation was defined as the angle between the long axis of M3 and the mandibular occlusal plane. Condylar fracture patterns were classified as intracapsular (Types A-C) or extracapsular (neck and base). Data were analyzed using McNemar-Bowker test, Pearson chi-squared test, and Fisher's exact test.

RESULTS

Classification of M3 position differed significantly between panoramic radiography and computed tomography images (p < .05). There was a significant association between the mandibular condylar fracture pattern and M3 horizontal position on computed tomography (p < .05). Class I M3 position on computed tomography was associated with a higher incidence of intracapsular than extracapsular fractures, along with a higher incidence of Type B than base fractures; the opposite relationships were observed for Class II. No such association was identified on panoramic radiography.

CONCLUSIONS

Mandibular condylar fracture patterns were presumably influenced by M3 horizontal position on computed tomography. The imaging modality affected the classification of M3 position and subsequent analyses. Computed tomography is recommended for future studies to improve accuracy and reliability.

A Comprehensive Look at Maxillofacial Traumas: On the Basis of Orbital Involvement

INTRODUCTION

Orbital wall fractures that may develop in maxillofacial traumas (MFTs) may cause ophthalmic complications (OCs). The aim of this study is to determine the frequency of orbital fractures (OFs) accompanying MFTs and findings suspicious for orbital traumatic involvement.

MATERIALS AND METHODS

Computed tomography (CT) images of 887 patients who presented to the emergency department within a 1-year period with a history of MFT were retrospectively scanned. During the examination, patients with orbital wall fractures, craniofacial bone fractures, and posttraumatic soft tissue changes were recorded.

RESULTS

OF was observed in 47 (5.3%) of the patients admitted for MFT. In cases with OFs, accompanying nasal (25.5%), ethmoid (2.1%), frontal (19.1%), maxillary (38%), and zygomatic bone fracture (10.6%), sphenoid (4.3%), and soft tissue damage (55.3%) were observed. It was observed that the pathologies mentioned at these levels were significantly higher than in patients without orbital involvement (p < 0.05). In our study, mild (48.9%) and moderate-severe (2.12-4.25%) OCs accompanying OFs were observed after MFT.

CONCLUSIONS

The frequency of MFT varies depending on various factors, and such studies are needed to take preventive measures. Knowing the risk and frequency of orbital damage accompanying MFTs may help reduce complications by allowing rapid and accurate diagnosis.

Pattern of oral and maxillofacial trauma and associated factors: An 8-year prospective study

BACKGROUND/AIMS

Oral and maxillofacial trauma (OMFT) is a public health problem due to its high occurrence and demand for resources for its management and the financial and social impact of OMFT victims on the health system. The aim of this study was to conduct an 8-year prospective analysis of OMFT cases from an emergency service.

MATERIALS AND METHODS

A hospital-based 8-year prospective study on OMFT and associated factors was performed on data from December 2011 to December 2019. Data regarding sociodemographic (gender, age, and skin color) and socio-economic profiles (educational level, family income, and occupation), OMFT profile (etiology, OMFT type, and treatment), associated factors [alcohol consumption and personal protective equipment (PPE) use], OMFT occurrence (injury day and hour), length of hospital stay, and cost were collected. Descriptive and inferential analyses of data were performed.

RESULTS

Most OMFT cases involved men with low schooling and family income, resulting from traffic accidents. OMFT severity was associated with longer hospital stay, higher hospital costs and nonuse of PPE, midface fractures (mainly orbital-zygomatic fractures), closed reduction, and open reduction/internal fixation. Traffic accidents were the main cause of longer hospital stays for victims aged 41-60 years with better socio-economic status compared with cases that had higher hospital costs. In general, higher hospital costs were associated with victims of violence under 40 years of age, with low schooling and farmers. Alcohol consumption and non-use of PPE also contributed to increasing the length of hospital stay.

CONCLUSION

Oral and maxillofacial trauma severity was associated with longer hospital stay and higher hospital costs. Associated factors such as alcohol consumption and non-use of PPE contributed to increase the length of hospital stay and OMFT severity.

Demographic Discrepancies of Vitamin D Deficiency in Craniofacial Fracture Patients

Background

The relationship between craniofacial fracture and vitamin D status has not been studied. Given the important role vitamin D status plays in postfracture prognosis, a deep investigation into this relationship is due. The primary objective of this study was to assess the demographic discrepancies in the vitamin D status of patients with craniofacial fracture.

Methods

The Cerner Health Facts database was used to collect data on serum 25-hydroxyvitamin D, demographics, hospital admission and discharge, and fracture type of 76 craniofacial fracture patients with available vitamin D levels from October 2015 until May 2018. Pairwise Spearman Correlation was used for multivariate data analysis.

Results

Of the 76 craniofacial fracture patients identified, 55.3% were insufficient in vitamin D and 32.9% were deficient in vitamin D. Vitamin D deficiency and insufficiency were more common in women, African American individuals, and patients over 50 years of age.

Conclusions

The investigation revealed a high prevalence of vitamin D deficiency and insufficiency in craniofacial fracture patients. Despite the higher incidence of fractures in men and Caucasian individuals, women and African American individuals with craniofacial fractures had poorer vitamin D status. Clinicians should consider empiric vitamin D supplementation following craniofacial fracture in high-risk groups.

Significance of subconjunctival hemorrhage in predicting ocular pathology for patients with orbital fracture

OBJECTIVE

Subconjunctival hemorrhage (SCH) is a common presentation in patients with orbital trauma and often warrants investigation of underlying ocular pathology. Our study aims to assess the significance of SCH severity, graded in a spatial 0-360° manner, as a predictor for ocular pathology in patients with orbital fracture.

DESIGN

Retrospective chart review.

PARTICIPANTS

Patients with fractured orbits (n = 265) presenting to a level 1 trauma centre between August 2015 and January 2018.

METHODS

Key elements of ophthalmic assessment, including visual acuity, SCH (0-360°), anterior- and posterior-segment examination, Hertel exophthalmometry, and ocular pathology, were recorded. Simple logistic regression assessed for association between SCH severity and ocular pathology. Odds ratios (ORs) were calculated with 95% CI.

RESULTS

Among the 265 fractured orbits, 158 (59.6%) presented with no SCH, and 107 (40.4%) had some degree of SCH. Ocular pathology was noted in 24 fractured orbits (9%). Most common pathologies included entrapment (22.2%), hyphema (16.7%), traumatic optic neuropathy (8.3%), and commotio retinae (8.3%). Simple logistic regression revealed a higher incidence of ocular pathology with increasing severity of SCH from 0-360° (OR = 1.004; 95% CI 1.001-1.007; p = 0.0085). In addition, χ² analysis demonstrated a higher proportion of ocular pathology in 181-270° (25.0%; p = 0.0466) and 271-360° SCH subgroups (26.3%; p = 0.0031) compared with the 0° SCH subgroup (6.3%).

CONCLUSIONS

Our findings suggest that there is some correlation between the extent of SCH and ocular pathology. However, patient care and investigations should continue to be directed by a full clinical assessment of patients with orbital trauma.

Maxillofacial trauma due to traffic accidents and falls: an exploratory study of associated factors

Background

This study aimed to determine the pattern of Maxillofacial trauma (MFT) due to traffic accidents and falls in a reference hospital in a rural region of northeastern Brazil between December 2011 and December 2018 and to identify associated factors.

Material and Methods

This was a cross-sectional study using 585 medical records of patients with MFT. The data were subjected to a Poisson-Tweedie multiple regression analysis to estimate the Prevalence ratio (PR), with a 95% confidence interval (95% CI) and a significance level of p<0.05.

Results

MFT due to traffic accidents was more prevalent among patients 21 to 40 years old (PR=2.30; 95% CI=1.20-4.41; p<0.001) diagnosed with zygomatic-orbital complex fractures (PR=1.80; 95% CI=1.08-2.98; p=0.023). Falls were more frequent among older groups of 41 to 60 years (PR=1.83; 95% CI=1.09-3.06; p=0.022) and over 61 years (PR=2.23; 95% CI=1.09-3.06; p=0.022). In traffic accidents, alcohol consumption increased the length of stay (PR=2.081; 95% CI=1.553-2.787; p<0.001), and patients who did not use personal protective equipment (PPE) had higher hospital costs (PR=179.964; 95% CI=1.485-1.994; p<0.001) for this etiology. Traffic accidents and falls are two of the main etiologies of MFT, especially for males in the young adult age group (traffic accidents) and those above 41 years (falls). Alcohol consumption and the nonuse of PPE influenced the length of the hospital stay and hospital costs.

Conclusions

Strategies to confront this problem, such as road and highway improvements, effective enforcement of laws and intersectoral coordination involving the entire community to implement policies and prevention programs targeted at these populations, can be implemented.

The Epidemiology and Management of Maxillofacial Fractures at a Tertiary Care Hospital in a Conflict-Torn Region in Somalia

The etiology of maxillofacial fractures (MFFs) varies according to the geographical location and density of the population. This study aimed to analyze the etiology, pattern, and treatment of MFFs. Epidemiological characteristics and treatment modalities of MFFs have never been evaluated in Somalia. The study included 45 patients who were operated on for MFFs at a tertiary care hospital in Somalia (2018-2019). Patient demographics, fracture causes, types, associated non-facial injuries, treatment modalities, and hospitalization-time were evaluated. The most common etiological factors of the MFFs were explosion (24.4%) and assault (24.4%), followed by gunshot (22.2%), sports accident (15.6%), motor vehicle accident (11.1%), and fall from height (2.2%) patients, respectively. The main site of injury was the mandible bone (64.4%) followed by nasal bone, maxilla, zygomatic, and orbital region. The most common non-facial injuries of the MFFs were soft tissue laceration (37.8%) followed by femoral fracture (6.7%), clavicle fracture (4.4%), and femoral fracture with chest injuries (2.2%). The most applied treatment was open reduction microplate +/- intermaxillary fixation (77.8%). Due to the size of the mandible fractures, an iliac autograft (6.7%) was performed. The mean length of the hospital stay was 11.8 +/- 8.4 days (range, 1-45 days), and some patients (15.6%) needed intensive care due to severe injuries. This will be the first study aiming to analyze the etiology, pattern, and treatment of MFFs in Somalia. This study deals with the social aspects of Somalia, and it shows that MFFs develop as a result of highly interpersonal violence in a young man.

An epidemiological analysis of maxillofacial fractures: a 10-year cross-sectional cohort retrospective study of 1007 patients

Background

Epidemiological data is providing vital indicators for organizing the financial resources related to a particular type of trauma, estimating expenses and training of dental practioners and ambulatory medical staff for collaboration with a certain pattern of patients. Knowing the etiology and epidemiology of a certain pathology is significant for approaching its means of prevention.

Methods

A 10-year retrospective statistical analysis of 1007 patients with maxillofacial fractures treated in a University Clinic of Oral and Maxillofacial Surgery in Romania was performed. The data were extracted from patients’ medical records. Statistical analysis was performed. A value of p < 0.05 was considered statistically significant.

Results

The incidence of maxillofacial fractures was high among patients in the 20–29 age group (35.9%). Male patients (90.57%, M:F = 9.6:1), having a low level of education (46.60%) and living in urban areas (53.50%) were more affected. The main cause of maxillofacial fractures was interpersonal violence (59.37%), both in the mandibular and midface topographic regions (p = 0.001, p = 0.002). In urban areas, fractures caused by interpersonal violence and road traffic accidents were predominant, while in rural areas, most of the fractures were due to interpersonal violence, domestic accidents, work accidents and animal attacks (p = 0.001).

Conclusions

Interpersonal violence is the main cause of maxillofacial fractures having epidemic proportions. Male patients aged 20–29 years with a low level of education represent the major risk category. Considering the wide area of interpersonal aggression, both the medical staff in the hospital and in the dental offices must be educated in order to collaborate with possible violent patients. Dentists must be prepared to work on a post-traumatic dento-periodontal field. Taking all measures to prevent inter-human aggression is imperative and will lead to a major decrease in maxillofacial fractures and an overall increase of oral health in a population.

Epidemiological Analysis of Zygomatic Bone Fractures in North-Western Romanian Population: A 10-Year Retrospective Study

BACKGROUND/AIM

Midface fractures represent a challenge for medical practitioners due to the severe esthetic and functional consequences. This study aimed to determine the causes and to provide a demographic analysis of zygomatic bone fractures in our geographical area, with a view to implementing the necessary prevention methods, training the medical staff for a certain type of patients and decreasing the required costs.

PATIENTS AND METHODS

A retrospective statistical epidemiological analysis of 242 patients with zygomatic bone fractures over a 10-year period was performed.

RESULTS

The most affected age group was 20-29 years (27.27%). The most affected were men (n=211, 87.19%) from urban areas (n=140, 57.85%), and without education (n=122, 50.41%). The most frequent cause was interpersonal violence (54.04%), followed by falls (17.36%) and road traffic accidents (16.53%).

CONCLUSIONS

Interpersonal violence as a cause of zygomatic bone fractures is currently reaching epidemic proportions. Taking legal measures to prevent aggression is a public health emergency that would considerably decrease the incidence of these fractures in our population.

The Implications of Titanium Alloys Applied in Maxillofacial Osteosynthesis

Titanium alloys are known for their biological, mechanical and chemical properties, which have successfully expanded their use in the maxillofacial field. The internal fixation using titanium miniplates and screws offer a new perspective for the treatment of trauma and in orthognathic surgery and maxillofacial oncology. Although, titanium is highly recommended for its excellent biocompatibility, recent research has focused on identifying the potential local and general implications of the interactions between the human tissue and the metallic particles. This present review aims to outline the existing tissue changes, cellular alterations and future perspectives regarding the use of titanium-based alloys as osteosynthesis materials, taking into consideration the existing present debate whether the routinely removal of these materials should be an indication.

Pediatric-Specific Midfacial Fracture Patterns and Management: Pediatric Versus Adult Patients

PURPOSE

The purpose of this study was to compare the midfacial fracture patterns and management approaches between pediatric and adult patients.

METHODS

We retrospectively analyzed 164 pediatric patients (<16 years old) and 564 nongeriatric adult patients (16 to 65 years old) with midfacial fractures at a single institution between 2011 and 2016. The location of the fractures, along with the etiology and management of the midfacial fractures, were compared.

RESULTS

Significantly greater proportions of pediatric versus adult patients had sports-related injuries (P < 0.001) and sustained nasal fractures (P < 0.001). On the other hand, significantly greater proportions of adult versus pediatric patients were injured in falls, traffic accidents, or assaults (P = 0.004, P < 0.001, and P = 0.002) and sustained maxillary or zygomatic fractures (P = 0.039 and P < 0.001). Bivariate logistic regression analyses revealed that the risks of nasal, maxillary, and zygomatic fractures were significantly related to age status after adjusting for etiology (P < 0.001, P = 0.045, and P < 0.001). In contrast, the risks of hospitalization and surgical treatment were significantly associated with etiology, but not with age status (P = 0.290 and P = 0.847).

CONCLUSION

These data suggest that the age-related structure and composition of the facial skeleton affect the pediatric-specific fracture patterns independent of the etiology. The comparisons in this study may serve as a guide for the management of pediatric midfacial fractures.

No Need to Routinely Remove Titanium Implants for Maxillofacial Fractures

PURPOSE

Titanium implants are typically used to fix maxillofacial fractures and their routine removal is a controversial topic in maxillofacial surgery. This study aimed to estimate the removal rate and risk factors associated with removal.

MATERIALS AND METHODS

The authors designed and implemented a retrospective study. Adult patients who underwent open reduction and internal fixation with titanium implants for maxillofacial fractures were included and those who returned for implant removal were identified from January 2007 to December 2016. The predictor variables were gender, age, preoperative infection, injury time, trauma cause, and fracture site. The primary outcome variable was removal of titanium implants. Descriptive and bivariate statistics were computed. Kaplan-Meier survival methods were used to estimate rate of removal. Univariate and multivariate Cox proportional hazards models were used to identify risk factors associated with removal.

RESULTS

Of 2,325 patients (1,890 men and 435 women; average age, ∼35.49 yr) registered in this study, 163 (7.01%) had their titanium implants removed and 1-, 2-, and 10-year removal rates were 3, 7, and 8%, respectively. The risk factors most closely associated with removal were preoperative infection, injury by a blow from an object, obsolete fracture, and female gender.

CONCLUSIONS

Routinely removing titanium implants in patients with maxillofacial fracture is not necessary. When the risk factors listed earlier are present in these patients, follow-up should be scheduled more frequently.

Fracture patterns and causes in the craniofacial region: an 8-year review of 2076 patients

Background

For proper recovery from craniofacial fracture, it is necessary to establish guidelines based on trends. This study aimed to analyze the patterns and causes of craniofacial fractures.

Methods

This retrospective study analyzed patients who underwent surgery for craniofacial fractures between 2010 and 2017 at a single center. Several parameters, including time of injury, region and cause of fracture, alcohol intoxication, time from injury to surgery, hospitalization period, and postoperative complications, were evaluated.

Results

This study analyzed 2708 fracture lesions of 2076 patients, among whom males aged 10 to 39 years were the most numerous. The number of patients was significantly higher in the middle of a month. The most common fractures were a nasal bone fracture. The most common causes of fracture were ground accidents and personal assault, which tended to frequently cause more nasal bone fracture than other fractures. Traffic accidents and high falls tended to cause zygomatic arch and maxillary wall fractures more frequently. Postoperative complications—observed in 126 patients—had a significant relationship with the end of a month, mandible or panfacial fracture, and traffic accidents.

Conclusions

The present findings on long-term craniofacial fracture trends should be considered by clinicians dealing with fractures and could be useful for policy decisions.
