RESUMO

In addition to the clinical burden of trauma, the financial burden is an important aspect of care globally, especially for patients in low- and middle-income countries. The current retrospective review was done of data from January 2015 to December 2020 related to patients of oral maxillofacial trauma management in a tertiary care setting. Analysis of variance was used to determine the mean difference in the cost incurred depending upon the type of trauma and the number of bone plates used in fracture management. Pearson correlation was applied to explore any correlation involving patient age, aetiology and type of fracture, number of bone plates employed and the length of stay in the hospital. No statistically significant differences were noted in the cost among the different groups. The cost of care was significantly (p<0.001) correlated to the length of stay. Other variables, such as the type of fractures and the number of plates, had no significant impact (p>0.05).

RESUMO

Literature describes variable rates of diplopia of associated with zygomatic maxillary complex (ZMC) fractures (6% to 40%). The aim of this study was to retrospectively assess the prevalence of diplopia in ZMC fracture patients, the usefulness of the orthoptic evaluation compared with the clinical finger-tracking examination, and to seek possible relations of this symptom with clinical parameters. Data of patients attending the Maxillofacial Surgery Units of the University of Messina and University of Naples "Federico II", between January 2012 and December 2022 were retrieved. Statistical analysis of positive versus negative diplopia at both the clinical examination and the orthoptic evaluation and subgroup analysis were performed. 320 patients were included in the analysis. 50 (15.6%) patients reported diplopia at the clinical examination, whereas 70 (21.9%) resulted positive at the orthoptic evaluation. Statistical analysis for every determinant and subgroup did not show statistical significance ( P >0.05). Performing routine preoperative orthoptic evaluation allowed an increase of 6.3% in positive reports. Although it seems that no basic clinical parameter can predict diplopia, results suggest that the orthoptic evaluation is superior in the assessment of this symptom. Clinical analysis was shown to be a moderate/low efficient test and should not be used as a decisional standard.

RESUMO

The aim of this article was to evaluate the efficacy of tranexamic acid (TXA) to reduce blood loss after maxillofacial fracture surgery. Clinical data were collected retrospectively on patients with unilateral fractures of the zygomaticomaxillary complex (ZMC) or mandibular condyle. Patients were then further divided into TXA and control groups according to whether or not TXA was used after surgery. The amount of postoperative blood loss was evaluated by negative pressure drainage volume. Data were statistically analysed. In patients with unilateral ZMC fractures, total postoperative blood loss in the TXA group was about 30 ml less than that in the control group (p = 0.006). It was significantly less on the first and second postoperative days. However, in patients with unilateral mandibular condylar fractures, there was no significant difference between the TXA and control groups (p = 0.917). TXA can reduce postoperative bleeding in patients with ZMC fractures, and the optimal usage time is on the first and second postoperative days. For patients with mandibular condylar fractures, TXA may not be used.

RESUMO

Posttraumatic and postsurgical sensory disturbance is a known complication of almost all zygomaticomaxillary (ZMC) complex fractures involving the infraorbital nerve, for which few treatments are effective. Our study used neurosensory assessments to evaluate the efficacy of melatonin on pain and nerve healing following ZMC surgery. Sixty-four randomly allocated ZMC fracture patients were prophylactically administered either oral melatonin or an identical placebo for 15 consecutive days. Pre- and postsurgical clinical parameters included subjective pain, numbness, and objective neurosensory function. Melatonin significantly reduced subjective pain perception in the early postoperative days, with a significant difference in VAS scores between the groups from postoperative day 3 (p = 0.048) until day 7 (p = 0.002). The VAS assessment of subjective numbness perception showed significantly lower self-perceived neurosensory disturbance for patients in the interventional group from the first month (p = 0.039) until the third month (p = 0.005). Objective neurosensory assessment using the pinprick test and two-point discrimination showed statistically significant improvement to almost normal sensation by the first month (p = 0.014) to fully normal sensation by the third month (p = 0.001). The study findings suggest that the prophylactic administration of melatonin confers significant clinical benefits in terms of reduced postoperative pain and improved sensory recovery.

RESUMO

OBJECTIVE: This study aims to quantify the facial symmetry of surgically treated zygomaticomaxillary complex (ZMC) fractures through a new reliable three-dimensional evaluation method, which is crucial for improving post-operative aesthetic and functional outcomes. MATERIAL AND METHODS: Healthy patients and patients with surgically treated ZMC fractures were retrospectively reviewed. Using Brainlab Elements® the zygomatic bone and the orbit of each patient was segmented and mirrored. Subsequently, the mirrored side was matched with the other side via volume-based registration, using the segmented orbit as reference. Volumetric asymmetry was measured using 3-matic software, and a surface-based matching technique was used to calculate the mean absolute differences (MAD) between the surfaces of the two sides of the ZMC. The reliability of this novel method using volume-based registration was tested, and the intra-class correlation coefficient was assessed. RESULTS: The MAD between the surfaces of the left and right sides in the control group was 0.51 mm (±0.09). As for the ZMC fracture group, MAD was 0.78 mm (±0.20) and 0.72 mm (±0.15) pre- and post-operatively, respectively. The MAD showed statistically significant differences between pre- and post-operative groups (p = 0.005) and between control and post-operative groups (p < 0.001). The intra-class correlation coefficient was high (≥0.99). CONCLUSIONS: This evaluation method using mirroring and volume-based registration to determine the symmetrical position of the ZMC is reliable. The surface-based measurements revealed an improved symmetry after surgery. However, the symmetry of the treated patients remained lower than the control group.

RESUMO

Our study aimed to evaluate modified patient-specific surgical-guide-assisted precise treatment of unilateral comminuted zygomaticomaxillary complex (ZMC) fractures. The retrospective non-randomized study was conducted in a single hospital in China. All patients diagnosed with unilateral comminuted ZMC fractures between January 1, 2018 and December 31, 2022 were retrospectively reviewed. All patients underwent preoperative spiral computed tomography (CT). CT data were processed using software to DICOM format and transferred to Proplan CMF3.0 for preoperative virtual surgical planning and postoperative evaluation. All data were extracted from standardized electronic medical records. All statistical analyses were performed using SPSS version 20.0. The chi-square test and t-test were used for statistical analyses. The 54 included patients were divided into two comparable, equal cohorts of 27 patients, and followed up for at least 6 months. Fracture reduction was assisted using the modified patient-specific surgical guides in the guide group (23 males, four females; mean age 37.74 ± 12.07 years) and without the modified patient-specific surgical guides in the control group (20 males, seven females; mean age 37.44 ± 13.58 years). In the guide group, the mean eminence deviation between the affected and unaffected sides was 1.01 ± 0.92 mm, and the mean width deviation between the affected and unaffected sides was 1.29 ± 1.32 mm. In the control group, the mean eminence deviation between the affected and unaffected sides was 1.99 ± 1.69 mm, and the mean width deviation between the affected and unaffected sides was 2.68 ± 2.01 mm. The differences in facial protrusion (p = 0.001) and width (p = 0.003) symmetry between the affected and healthy sides of the two groups were statistically significant (p < 0.05). In conclusion, applying the modified patient-specific surgical guides to unilateral comminuted zygomaticomaxillary complex fracture reduction has the advantages of greater predictability and effectiveness, and improved bilateral ZMC symmetry. It should be noted that this approach would be especially beneficial for less-experienced surgeons.

RESUMO

Gillies temporal approach has been widely used to reduce zygoma fractures. Traditionally, it is the preferred method to reduce the isolated zygomatic arch fracture. It can be combined with other approaches, such as subciliary and intraoral incisions for more complex zygomatic fractures, so-called tripod fractures. In this study, the author hypothesized that complex zygomaticomaxillary bone fracture reduction can successfully be achieved without Gillies temporal incision. The author retrospectively analyzed the medical records and 3D facial Computed Tomography (CT) scans of 80 patients who had orbitozygomaticomaxillary fractures that affected >3 sites among the frontozygomatic suture, zygomaticomaxillary buttress, zygomatic arch, and orbital walls from May 2021 to August 2023. A single surgeon performed all surgical operations. All fractures were reduced with 2 incisions, lower eyelid incisions (subciliary or subconjunctival) and intraoral incisions (gingivobuccal approach), within a week of the initial traumatic event. After sufficient exposure to fractured sites using 2 incisions, the author reduced the fracture with a bony hook at the inferior orbital rim, lateral wall, or Boise elevator at the intraoral incision. All cases were successfully corrected without any complications. In conclusion, the author can successfully reduce complex zygomaticomaxillary fracture combined with orbital wall fractures without temporal Gillies approach.

RESUMO

BACKGROUND: One-point fixation was superior to the two and three-points fixation in minimally displaced zygomaticomaxillary complex (ZMC) fracture regarding the cost, invasiveness, scaring, number of wounds, and operation time. Accordingly, this study aimed to predict which one-point fixation is the most stable in managing minimally displaced ZMC fracture. MATERIAL & METHODS: This study simulated the different one-point fixation approaches on three ZMC models after fracture reduction and application of all forces exerted on the fractured area. The findings were represented as stress impact on the ZMC fracture and plating system as well as the inter-fragments micro-motion. RESULTS: The von misses stresses of plates for the zygomaticofrontal, infra-orbital rim, and zygomaticomaxillary buttress model were (66.508, 1.285, and1.16 MPa) respectively. While the screws' von misses for the infraorbital rim, zygomaticofrontal, and zygomaticomaxillary buttress models were (13.8, 4.05, and 1.60 MPa) respectively. Whereas, the maximum principles stress at zygomaticofrontal, zygomaticomaxillary buttress, and infraorbital rim models were (37.03, 37.01, and 34.46 MPa) respectively. In addition, the inter-fragment micro-motion for zygomaticomaxillary buttress, infraorbital rim, and zygomaticofrontal models were (0.26, 0.25, and 0.15 mm) respectively. CONCLUSION: One-point fixation at zygomaticomaxillary buttress is the preferred point because it is exposed to low stresses, and the inter-fragment micro-motion is within the approved limit with the elements in the same direction of fixation which indicates the rigid fixation. In addition, it is less palpable and scarless. TRIAL REGISTRATION: clinical trial.gov (NCT05819372) at 19/04/2023.

RESUMO

BACKGROUND: Due to the complex anatomical morphology and lack of anatomic markers on the surface of zygomatic complex (ZMC), the treatment results of ZMC fractures are often suboptimal. PURPOSE: The study aimed to evaluate the effectiveness of intraoperative computed tomography (ICT) in the treatment of unilateral ZMC fractures, and further study the feasibility of ICT to replace early postoperative Computed Tomography (CT). STUDY DESIGN, SETTING, AND SAMPLE: The investigators designed a retrospective cohort study. Adult patients who underwent surgery with unilateral ZMC fractures were enrolled. PREDICTOR VARIABLE: According to whether intraoperative CT was used, the subjects were divided into the ICT group and the control group (without ICT). MAIN OUTCOME VARIABLES: Five distances and 3 angles representing bilateral ZMC symmetry were main outcome variables. The differences of outcome variables were compared between the 2 groups and the indices of ICT group were further compared with their postoperative indices. COVARIATES: Demographics (eg age), etiology (eg traffic injury), dysfunction (eg diplopia), and surgical approach (eg vestibular incision) were collected as covariates while we conducted clinical investigation, examination, and implementation. ANALYSES: The data were analyzed using independent-samples t test, paired-samples t test, Mann-Whitney U test, and χ2 test. P value < .05 was considered statistically significant. RESULTS: A total of 60 patients (18 to 59 years) were enrolled in this study. All median values of the measurements in the ICT group were smaller than those in the control group, and the differences of horizontal displacement distance (0.56 vs 1.02 mm), anteroposterior displacement distance (1.69 vs 2.34 mm, 0.90 vs 2.35 mm), horizontal angle of bilateral zygomatic arch (2.31 vs 4.19°), and horizontal angle of bilateral zygomatic process (1.77 vs 2.94°) were significantly different between the 2 groups with P value < .05. Moreover, there was no statistically significant difference in all indices between the intraoperatively and postoperatively injured sides in the ICT group. CONCLUSIONS: ICT can improve the treatment outcomes of ZMC fractures by evaluating the fracture reduction adequacy during surgery. Moreover, ICT can replace early postoperative CT.

RESUMO

BACKGROUND: Nasoorbitoethmoid (NOE) fractures impact growth of the craniofacial skeleton in children, which may necessitate differentiated management from adult injuries. This study describes characteristics, management, and outcomes of NOE fractures in children seen at a single institution. METHODS: A retrospective review of patients under 18 years who presented to our institution from 2006 to 2021 with facial fractures was conducted; patients with NOE fractures were included. Data collected included demographics, mechanism of injury, fracture type, management, and outcomes. RESULTS: Fifty-eight patients met inclusion criteria; 77.6% presented with Manson-Marcowitz Type I fractures, 17.2% with Type II, and 5.2% with Type III. The most common cause of injury was motor vehicle accidents (MVAs, 39.7%) and sports (31%). Glasgow Coma Scale and injury mechanism were not predictive of injury severity in the pediatric population ( P =0.353, P =0.493). Orbital fractures were the most common associated fractures (n=55, 94.8%); parietal bone fractures were more likely in Type III fractures ( P =0.047). LeFort III fractures were more likely in type II fractures ( P =0.011). Soft tissue and neurological injuries were the most common associated injuries regardless of NOE fracture type (81% and 58.6%, respectively). There was no significant difference in type of operative management or in the rates of adverse outcomes between types of NOE fractures. CONCLUSIONS: These findings suggest that pediatric NOE fractures, although rare, present differently from adult NOE fractures and that revisiting predictive heuristics and treatment strategies is warranted in this population.

RESUMO

A sagittal fracture at the temporal root of the zygomatic arch (ZAR) often occurs as a component of zygomaticomaxillary complex (ZMC) fractures. However, this area is difficult to access, and anchorage is limited due to the unstable structure around it. Therefore, a preauricular approach using single-screw fixation is proposed, and this study reports its results and usefulness. Forty-four patients with sagittal fractures of ZAR occurring with ZMC fractures were evaluated from 2012 to 2021. Open reduction and internal fixation were performed on all patients with ZMC fractures. Closed reduction using Dingman incision and external finger pressure in group A (indirect approach; 30 patients) and single-screw fixation using a preauricular approach in group B (direct approach; 14 patients) were performed to address sagittal fractures in ZAR. For single-screw fixation, the additional mean operation time was 11.34±3.25 minutes. On postoperative 3-dimensional computed tomography and plain radiographs, group B showed more accurate reduction and less deformity and trismus ( P <0.05). Moreover, a normal diet was initiated more quickly in group B than in group A ( P <0.05). Some cases in group A showed nonunion or malunion. This study revealed that a direct approach (group B) toward sagittal fractures of ZAR is recommended due to more accurate results and fewer complications than those observed with the indirect approach (group A). Moreover, the total operation time and complications may be lesser than those with the bicoronal approach.

RESUMO

Fixation is critical in zygomaticomaxillary complex (ZMC) fractures to avoid malunion; however, controversy exists as to how much hardware is required to achieve adequate stability. Current fixation regimens may not represent the minimum stabilization needed for uneventful healing. Craniomaxillofacial (CMF) computational models have shown limited load transmission through the infraorbital rim (IOR), and a previous experimental study of ZMC fractures has suggested that IOR plating does not alter CMF bone strain patterns. This study aimed to measure the impact of stabilization on fracture site displacement under muscle loading, testing the hypothesis that three-point fixation is not critical for ZMC fracture stability. Four ZMC complex fractures were simulated on two cadaveric samples and stabilized with three-point plating. Displacements simulating mouth openings of 20 mm and 30 mm were applied to the mandible using a custom apparatus. Fracture gap displacement under load was measured at multiple points along each fracture line, and bone strain was captured using a combination of uniaxial and rosette gauges. Data capture was repeated with the IOR plate removed (two-point fixation) and with the zygomaticomaxillary plate removed (one-point fixation). Fracture displacement under muscle loading was consistent, with gaps of less than 1 mm in 95% of cases (range 0.05-1.44 mm), reflecting clinical stability. Large variabilities were observed in the strain measurements, which may reflect the complexity of CMFS load patterns and the sensitivity of strain values to gauge placement. This study supports the concept of hardware reduction, suggesting that two-point (or even one-point) fixation may provide sufficient stability for a ZMC fracture under applied muscle loading.

RESUMO

Fractures of the pediatric midface are infrequent, particularly in children in the primary dentition, due to the prominence of the upper face relative to the midface and mandible. With downward and forward growth of the face, there is an increasing frequency of midface injuries seen in children in the mixed and adult dentitions. Midface fracture patterns seen in young children are quite variable; those in children at or near skeletal maturity mimic patterns seen in adults. Non-displaced injuries can typically be managed with observation. Displaced fractures require treatment with appropriate reduction and fixation and longitudinal follow-up to evaluate growth.

RESUMO

BACKGROUND: Standing electric scooters (e-scooters) are a cost-effective and environmentally-friendly transport alternative, but also elicit substantial concern regarding associated craniofacial injuries. This study aims to describe the patient factors, procedural factors and post-operative outcomes of maxillofacial fractures caused by e-scooter accidents. METHODS: Retrospective chart review of patients aged 18 years or older who were surgically treated for these injuries in 2014-2020 at two Australian tertiary hospitals. RESULTS: There were 18 cases included. Most cases were male (66%). The mean age was 35 years. Common risk factors were alcohol use (86%) and lack of helmet use (62%). The most common fracture pattern was zygomatico-maxillary complex (ZMC) fractures (50%). There were no associated systemic injuries. Mean operation timing was 12 days post-injury for ZMC fractures and 3 days post-injury for condyle fractures. For ZMC fractures, the most common method of fixation was 2-point fixation (66%). For condyle fractures, the most common surgical approach was arch bars only (83%). Post-operative complications were reported in six cases, with malocclusion being the most common (n = 3). Revision surgeries were performed in two cases. CONCLUSIONS: Maxillofacial fractures associated with e-scooter accidents appear to be increasing in incidence. Robust longitudinal evaluations with larger sample sizes are required to better understand associated presentations, surgical approaches and post-operative complications.

RESUMO

Introduction: Orbital floor (OF) fractures accompany all zygomaticomaxillary complex (ZMC) fractures, but guidelines for repair of OF fractures in this setting are unclear. Objectives: To compare ophthalmologic outcomes of ZMC repair with and without concurrent OF repair. Methods: We retrospectively reviewed patients undergoing ZMC fracture repair with and without OF repair between 2016 and 2018. Patients were reviewed for demographics, preinjury characteristics, and ophthalmologic outcomes. Results: Of 61 total patients, 32 underwent concomitant OF repair while the remaining 29 underwent ZMC repair alone. The OF repair group had increased OF fracture size, displacement in the coronal plane, and malar eminence displacement (p < 0.05). Eight patients in the OF repair group had postoperative diplopia compared with no patients in the group without OF repair (p < 0.05). Conclusion: Retrospective analysis of ZMC fracture repair without and with OF repair did not reveal a significant difference in short-term ophthalmologic outcomes while controlling for fracture size.

RESUMO

This study aims to provide patient characteristics and short-term clinical outcomes of Le Fort fractures. Using the National Surgical Quality Improvement Program database from 2016 to 2019, cases involving Le Fort fractures on initial encounters were reviewed. 130 cases from 3293 facial fractures were identified. 70 cases were diagnosed with type I, 41 with type II, and 19 with type III. The male-to-female ratio was 4.9:1. Compared to geriatric patients (>65 years old), Le Fort fractures were more common among patients between the ages of 18 and 65 (P < .003). 5.4% of patients had in-hospital complications, including sepsis, superficial-deep incisional surgical site infection, and wound disruption. Two patients (1.5%) were readmitted, while three (2.3%) underwent reoperation. Type I fractures in adult males are the most common presentation.

RESUMO

Among zygomaticomaxillary complex (ZMC) fractures presenting to a tertiary urban academic center, the authors hypothesized the presence of both clinical and radiographic predictors of operative management. The investigators conducted a retrospective cohort study of 1,914 patients with facial fractures managed at an academic medical center in New York City between 2008 and 2017. The predictor variables were based on both clinical data and features of pertinent imaging studies, and the outcome variable was an operative intervention. Descriptive and bivariate statistics were computed and the p-value was set at 0.05. In total, 196 patients sustained ZMC fractures (5.0%) and 121 (61.7%) ZMC fractures were treated surgically. All patients who presented with globe injury, blindness, retrobulbar injury, restricted gaze, or enophthalmos and a concurrent ZMC fracture were managed surgically. The most common surgical approach was the gingivobuccal corridor (31.9% of all approaches), and there were no significant immediate postoperative complications. Younger patients (38.9 ± 18 years vs. 56.1 ± 23.5 years, p < 0.0001) and patients with greater than or equal to 4 mm of orbital floor displacement were more likely to receive surgical treatment than observation (82 vs. 56%, p = 0.045), as were patients with comminuted orbital floor fractures (52 vs. 26%, p = 0.011). In this cohort, patients more likely to undergo surgical reduction were young patients with ophthalmologic symptoms on presentation and at least 4 mm displacement of the orbital floor. Low kinetic energy ZMC fractures may warrant surgical management as often as high-energy ZMC fractures. While orbital floor comminution has been shown to be a predictor for operative reduction, in this study we also demonstrated a difference in the rate of reduction based on the severity of orbital floor displacement. This may have significant implications in both the triage and selection of patients most suitable for operative repair.

RESUMO

Background: Victims of assault (VOA) often present with fractures of the mandible and maxilla. They represent a complex challenge because of possible compromise of the airway, and infection-related complications because of potential involvement of the oral cavity. We hypothesized that open mandible and maxillary fractures in VOA are associated with a higher rate of infection compared with non-VOA patients with open facial fractures. Patients and Methods: Patients admitted to our level 1 trauma center from 2005 to 2020 with a diagnosis of open mandible and maxillary fractures were included. Demographics, mechanisms of injury, fracture location, cultures, infectious complications, antibiotic treatments, and clinical outcomes were abstracted. Patients were stratified by their mechanism of injury into VOA or non-VOA and were compared using χ2 and Student t-test using SPSS (IBM Corp, Armonk, NY). Results: We identified 316 patients with open mandible and maxillary fractures. There were 198 patients categorized as being VOA, and 118 as non-VOA. Nineteen of 316 patients were diagnosed with infection related to the fracture (3.8% abscesses, 1.9% cellulitis, and 1.9% osteomyelitis). Although the Injury Severity Score (ISS) was higher in non-VOA patients (5.8 ± 2.6 vs. 4.9 ± 1.8; p < 0.013), most of the infections were in the VOA cohort (17/19; 89.5%; p < 0.013). Conclusions: Open fractures of the mandible and maxilla in VOA are associated with a greater risk of infection compared with non-victims of assault. The relation between VOA and poor SDH has been studied recently; clinicians should be aware of this association and implement special considerations and appropriate follow-up visits to decrease the rate of infection in this currently expanding population.

RESUMO

BACKGROUND: Few quantitative results are reported about the surgical effect of orbital reconstruction in Le Fort III fractures. The authors' team proposed an ordered surgery method which was effective for Le Fort III fractures. The aim of this study was to evaluate the effectiveness of this method with quantitative outcomes. METHODS: A retrospective study was conducted of all patients who were diagnosed with Le Fort III fractures and underwent orbital and facial fractures repair from January 2015 to June 2019. Surgical reconstruction was performed with an ordered surgery method. Orbital volumes were used to evaluate the effectiveness of orbital reconstruction. RESULTS: Fifteen patients (21 eyes) with Le Fort III fractures were included in this study. Preoperative and postoperative orbital volume changes were statistically significant ( P <0.01). For unilateral fractures, orbital volumes were different in 2 eyes ( P <0.01). For bilateral fractures, orbital volumes were almost the same in 2 eyes ( P =0.34). For the affected eye in unilateral fractures group and eyes in bilateral fractures group, after surgery, orbital volume were almost the same ( P =0.35). CONCLUSIONS: This study showed effectiveness and safety of the ordered surgery in the treatment of Le Fort III fractures, which would result in significant decrease in orbital volumes.
