RESUMO

BACKGROUND: Trauma-induced orbital blowout fracture (OBF) with eyeball displacement into the maxillary sinus is rare. CASE PRESENTATION: We present the case of a 14-year-old with a closed head injury, OBF, and displacement of the eyeball into the maxillary sinus following a car accident. A prompt transconjunctival access surgery was performed for eyeball repositioning and orbital reconstruction in a single session, mitigating anaesthesia-related risks associated with multiple surgeries. At the 12-month follow-up, his visual acuity was 20/200. Despite limited eye movement and optic nerve atrophy, overall satisfaction with the ocular appearance was achieved. CONCLUSIONS: This report offers novel insights into the mechanisms of OBF occurrence and the development of postoperative complications.

RESUMO

To clinically and radiographically evaluate patient-specific titanium meshes via a trans-antral approach for correction of enophthalmos and orbital volume in patients with recent unilateral orbital floor fracture. Seven patients with unilateral orbital floor fractures received patient-specific titanium meshes that were designed based on a mirror-image of the contralateral intact orbit. The patient-specific implants (PSIs) were inserted via a trans-antral approach without endoscopic assistance. The patients were evaluated clinically for signs of diplopia and restricted gaze as well as radiographically for enophthalmos and orbital volume correction. Diplopia was totally resolved in two of the three patients who reported diplopia in the upward gaze. Whereas enophthalmos significantly improved in all but two patients, with a mean value of 0.2229 mm postoperatively compared to 0.9914 mm preoperatively. CT scans showed excellent adaptation of the PSIs to the orbital floor with a mean reduction of the orbital volume from 29.59 cc to 27.21 cc, a mean of 0.6% smaller than the intact orbit. It can be concluded that the proposed PSI can offer good reconstruction of the orbital floor through an isolated intraoral transantral approach with minimal complications. It could of special benefit in extensive orbital floor fractures.

RESUMO

This study aimed to compare the accuracy of inferomedial orbital fracture restoration using customized orbital implant versus 3D preformed titanium mesh. Patients were divided into two groups. Group 1 underwent surgery with customized orbital implants and intraoperative navigation, while group 2 was treated using 3D preformed titanium meshes with preoperative virtual surgical planning (VSP) and intraoperative navigation. Reconstruction accuracy was assessed by: (1) comparing the postoperative reconstruction mesh position with the preoperative VSP; and (2) measuring the difference between the reconstructed and unaffected orbital volume. Pre- and postoperative diplopia and enophthalmos were also evaluated. Fifty-two patients were enrolled (25 in group 1 vs 27 in group 2). The mean difference between final plate position and ideal digital plan was 0.62 mm (SD = 0.235) in group 1 and 0.69 mm (SD = 0.246) in group 2, with no statistical difference between the groups (p = 0.282). The mean volume differences between the reconstructed and unaffected orbits were 0.95 ml and 1.02 ml in group 1 and group 2, respectively, with no significant difference between the groups (p = 0.860). Overall clinical improvements, as well as complications, were similar. 3D preformed titanium meshes can reconstruct inferomedial fractures with the same accuracy as customized implants. Therefore, in clinical practice, it is recommended to use 3D preformed meshes for this type of fracture due to their excellent results and the potential for reducing time and costs.

RESUMO

To compare the reconstruction of orbital fractures using patient-specific implants (PSI) and conventional pre-formed titanium mesh; to develop a method of three-dimensional (3D) superimposition and analysis of the reconstructed orbits; and to present the pitfalls in 3D planning of orbital PSI and how to avoid them. This was a retrospective study of patients with orbital fractures who were treated in our institution between the years 2022 and 2023 using PSI or conservative prefabricated titanium mesh. Three different methods for virtual reconstruction of orbital fractures were used and are detailed with advantages, disadvantages and indications. Data acquired included age, gender, method of reconstruction, functional outcomes and aesthetic outcomes. 3D analysis for accuracy of reconstruction was performed. A total of 23 patients were included; 12 were treated using PSI and 11 using prefabricated titanium meshes. There were 8 male and 4 female patients in the PSI group comparted to 5 and 6 in the prefabricated group. All three virtual methods for reconstruction were used successfully, each with the proper indications. When comparing PSI reconstruction to conventional mesh, a significant difference in accuracy was observed; PSI cases showed an inaccuracy of 0.58 mm compared to 1.54 mm with the conventional method. Complications are presented, and tips for avoiding them are detailed. Three different methods for virtual reconstruction were used successfully; automated computerized reconstruction is used for small defects, repositioning is the superior method for non-comminuted cases while mirroring is the method of choice in comminuted fractures. 3D analysis can be performed using a novel method detailed in this report. PSI reconstruction showed superior results, indicating it should be the method of choice when possible. Pitfalls are presented and approaches to prevent them are discussed. Orbital reconstruction is a very important entity in maxillofacial surgery with crucial functional and esthetical implications, and one should use virtual planning and PSI implants, as they significantly improve outcomes.

RESUMO

Postoperative diplopia is the most common complication following orbital fracture repair (OFR). Existing evidence on its risk factors is based on single-institution studies and small sample sizes. Our study is the first multi-center study to develop and validate a risk calculator for the prediction of postoperative diplopia following OFR. We reviewed trauma patients who underwent OFR at two high-volume trauma centers (2015-2019). Excluded were patients < 18 years old and those with postoperative follow-up < 2 weeks. Our primary outcome was incidence/persistence of postoperative diplopia at ≥ 2 weeks. A risk model for the prediction of postoperative diplopia was derived using a development dataset (70% of population) and validated using a validation dataset (remaining 30%). The C-statistic and Hosmer-Lemeshow tests were used to assess the risk model accuracy. A total of n = 254 adults were analyzed. The factors that predicted postoperative diplopia were: age at injury, preoperative enophthalmos, fracture size/displacement, surgical timing, globe/soft tissue repair, and medial wall involvement. Our predictive model had excellent discrimination (C-statistic = 80.4%), calibration (P = 0.2), and validation (C-statistic = 80%). Our model rules out postoperative diplopia with a 100% sensitivity and negative predictive value (NPV) for a probability < 8.9%. Our predictive model rules out postoperative diplopia with an 87.9% sensitivity and a 95.8% NPV for a probability < 13.4%. We designed the first validated risk calculator that can be used as a powerful screening tool to rule out postoperative diplopia following OFR in adults.

RESUMO

PURPOSE: To report adult patients with an orbital trapdoor fracture with extraocular muscle entrapment. METHODS: We retrospectively reviewed 566 adult patients (>18 years) with a pure orbital fracture who were referred to us from January 2016 to May 2023. The following data were collected: age, sex, affected side, causes of injury, concomitant ocular injury and nasal bone fracture, presence or absence of oculocardiac reflex and infraorbital nerve hypesthesia, period from injury to surgery, follow-up period, and pre- and postoperative limitation of extraocular muscle motility and fields of a binocular single vision. RESULTS: We found 5 patients (0.9%) with an orbital trapdoor fracture with extraocular muscle entrapment (age range, 19-47 years; all males; 2 right and 3 left). Causes of injury included performing a bench press, fall, assault, boxing, and bicycle accident. Entrapment of the inferior and medial recti muscles was seen in 2 and 3 patients, respectively. None of the patients had any sign of oculocardiac reflex. After surgical reduction, the field of binocular single vision became normal in 3 patients and was incompletely recovered in 2 patients, in whom consultation with us was delayed. CONCLUSION: Adults with extraocular muscle entrapment may not present with an oculocardiac reflex. Urgent release of an entrapped muscle is, however, still recommended to avoid permanent limitation of extraocular muscle motility.

RESUMO

Pediatric patients often present with orbital fractures after facial trauma, most commonly fractures of the orbital floor. Evaluation of orbital fractures for entrapment of the extraocular muscles is crucial, as urgent surgical exploration and possible repair are needed in these cases. We report a 2-year-old male who presented after a fall with multiple left orbital wall fractures, including a roof fracture. On examination, the patient's OS appeared fixed in an upward gaze. Positive forced ductions revealed clinical concern for entrapment of the superior rectus. The patient was taken to the operating room for exploration, and the entrapped superior rectus muscle was freed from the fracture. The patient subsequently recovered fully with complete extraocular movements. This represents the first reported case of superior rectus entrapment in an orbital roof fracture.

RESUMO

PURPOSE: Lower eyelid malposition can be a complication following orbital floor fracture surgeries. We present our incidence of lower eyelid malposition from a large case series of orbital floor fracture repairs using the 'swinging eyelid' approach and 'hang back' technique. METHODS: A retrospective review of all orbital fracture surgeries at our institution from November 2011 to March 2021 was performed. Primary outcomes included the incidence of lower eyelid malposition by category, the average time to presentation after primary surgery, and reoperation rates among cases with lower eyelid complications. RESULTS: A total of 438 cases that involved repair of the fractured orbital floor were identified. Six patients (1.37 %) developed lower eyelid malposition following primary orbital floor repair. Two patients (0.46 %) developed reverse ptosis of the lower eyelid. Two patients (0.46 %) returned with lower lid cicatricial ectropion. One patient (0.23 %) had postoperative lower eyelid retraction. One patient (0.23 %) had postoperative lower eyelid cicatricial entropion. No cases of lower lid flattening, lower eyelid fat flattening, or eyelid notch was noted. All patients with lower eyelid malposition underwent additional surgeries except one patient with reverse ptosis (83.3 %). The average time to the presentation of postoperative complications from the surgery date was 292.8 days (range = 49 days to 3.5 years). CONCLUSION: Lower eyelid malposition after orbital floor repair is a known complication that can be decreased by employing the 'swinging eyelid' with a preseptal approach and closure by the 'hang back' technique.

RESUMO

Preoperative computer-assisted planning and intraoperative navigation are becoming popular for orbital fracture treatment. However, not all institutions currently have access to these computer-aided applications. The authors present a simple and intuitive operative algorithm to guide orbital fracture reconstructions. The operative algorithm was based on linear measurements of orbital defects on high-resolution Computer tomography (CT) scans using specific axial, coronal, and sagittal plane images. The fractures were then divided into 3 types based on site and defect-size area. For each type, the authors suggested a surgical approach and material reconstruction. Between February 2022 and January 2023, 57 patients were treated according to the described CT-based protocol. The quality of reconstruction was classified as ideal, satisfactory, acceptable, and poor based on postoperative CT. Diplopia, enophthalmos, and postoperative complications were assessed. Fifty-seven patients were included. Forty-four (77.2%) patients were included in the type 1 group, 4 (7.01%) in the type 2 group, and 9 (15.79%) in the type 3 group. The reconstruction was considered ideal in 54 (94.7%) cases, satisfactory in 2 (3.5%), and acceptable in 1 (1.8%). No revision surgery was required. In all cases, preoperative diplopia was settled out, and only 1 patient reported postoperative enophthalmos. No complications occurred, with good clinical results and orbital symmetry. The linear CT measurement-based protocol is a simple and reliable workflow to guide the surgeon's choice of reconstruction material and surgical approach for primary orbital reconstruction. It allows good management of orbital trauma and could help standardize treatment decisions with an imaging technique available in all institutions.

RESUMO

OBJECTIVE: The optimal approach and timing of complex orbital fracture repair is an unresolved issue that is complicated by unique clinical presentations and patient-specific considerations. Early surgical repair in less than 14 days is associated with fewer complications; however, there are no guidelines addressing the optimal timing for surgical repair. This study assesses the time of surgical repair and surgical outcomes of complex orbital fractures. METHODS: Retrospective chart review from 2010 to 2022. Adult patients with orbital fractures are treated with surgical repair. RESULTS: In all, 94 patients presented with orbital fractures and were treated with 108 surgeries. Postoperative complications: vision disturbance 33/108 (30.6%), gaze restriction 12/108 (11.1%), lid malposition 10/108 (9.3%), globe complication 13/108 (12.0%), and hardware issues 14/108 (13.0%). Postoperative complications were not significantly associated with the surgical approach used for fracture repair or the time of surgical repair. CONCLUSION: Postoperative complications following surgical repair of orbital fractures are not associated with surgical approach or time of repair following the initial injury.

RESUMO

BACKGROUND: Although orbital fractures are common, prediction of outcomes in orbital surgery can be quite challenging. PURPOSE: We aim to identify predictors of intraoperative difficulty, operating time, and postoperative examination abnormalities in subjects undergoing post-traumatic orbital reconstructions. STUDY DESIGN, SETTING, AND SAMPLE: This is a retrospective cohort study of all consecutive orbital operations performed at a private, Level 1 trauma center in Portland, Oregon, USA over an 82-month period. All subjects that underwent exploration of the internal orbit for traumatic indications during the study period were included in the cohort. PREDICTOR VARIABLES: Four plating styles, surgical approach (transorbital vs transantral), days from injury to first surgery, fracture size (approximated as a rectangle using linear measurements from computed tomography scans), anteroposterior fracture position, and medial wall involvement were examined. OUTCOME VARIABLES: The primary outcome variable was intraoperative difficulty (defined as requiring revision after intraoperative imaging or return to the operating room). Secondary outcome variables included operating time and postoperative examination abnormalities. COVARIATES: Age and sex were included. ANALYSES: χ2 and Regression analyses were performed using a significance level of P < .05. RESULTS: One hundred and sixty four orbital operations were performed (90 isolated injuries and 74 combined orbital/midface injuries) on 155 subjects (73% male, mean age 39.8 years, standard deviation 16.7). In subjects with isolated orbital fractures, medial wall involvement was associated with intraoperative difficulty (P = .01). When using a transantral approach, intraoperative difficulty was more likely in more anterior fractures (P = .02). Plating style was associated with operating time (P = .03), with median times from 81 to 105 minutes (range 21 to 248 minutes). Postoperative examination abnormalities were more likely in the transorbital approach group (P = .01). Neither days to first surgery nor intraoperative difficulty were associated with postoperative examination abnormalities. Postoperative eyelid changes were seen in 13.6% of transorbital approaches and 0% of transantral approaches. Correction of gaze restriction and enophthalmos were more likely than correction of diplopia (P < .01). CONCLUSIONS AND RELEVANCE: Medial wall involvement is associated with intraoperative difficulty in orbital surgery. Anteriorly positioned fractures are better treated transorbitally, while posterior fractures may be amenable to transantral repair, thus avoiding risk of lower eyelid changes.

RESUMO

The aim of this study is to investigate the feasibility of perpendicular plate of ethmoid as material for the reconstruction of medial orbital wall. The main outcome measurement was preoperative and postoperative orbital volume. The authors performed a study including 17 patients who have isolated medial orbital wall fracture (blow-out fracture). All the patients were fixed the defect using autologous perpendicular plate of ethmoid under endonasal approach. The authors compared the preoperative and postoperative orbital volume difference (unaffected orbit, affected orbit) of all the patients, and observed the improvement of diplopia or ocular motility disorders after operation. All 17 medial orbital wall reconstruction surgeries were successful with no severe postoperative ophthalmic complications. Statistically significant differences were found between the preoperative and postoperative orbital tissue volumes for the affected orbit. There was no statistically significant difference found between the tissue volume of the contralateral unaffected orbit and the affected orbit after reconstruction. And postoperative computed tomography showed the implant is in place and there is no medial rectus incarceration. Autologous perpendicular plate of ethmoid proved to be safe and effective in the reconstruction of medial orbital wall under endonasal approach with cost-effectivence, low complication rate, high biocompatibility, and minimally invasion.

RESUMO

A few mucoceles developing secondary to facial bone fractures have been reported. Mucocele formation is thought to be attributable to displacement of the respiratory mucosa with obstruction of the sinus opening, especially if untreated. Accurate diagnosis and management are required; a growing mucocele will gradually destroy adjacent bony structures and cause irreversible complications. The authors describe a patient who presented with diplopia and mild discomfort when gazing upward. She had undergone reconstruction of medial and inferior orbital fractures 20 years previously. The patient was diagnosed with a mucocele developing after orbital fracture repair. The patient underwent mucocele removal and orbital reconstruction using a polyetheretherketone patient-specific implant. In a patient with orbital symptoms but without acute trauma, a mucocele should be among the differential diagnoses if history-taking reveals past orbital trauma and surgery. A polyetheretherketone patient-specific implant was effective for orbital reconstruction after mucocele removal.

RESUMO

BACKGROUND: The use of an acellular dermal matrix (ADM) has not been reported in medial orbital wall fracture reconstruction previously. This study aimed to share our early experience with the cross-linked ADM as an allograft material for medial orbital wall reconstruction. METHODS: In this study, the author evaluated the medical records and serial facial computed tomography scans of 27 patients with pure medial orbital wall fractures reconstructed by a single surgeon between May 2021 and March 2023. The author routinely approached the medial orbital wall with a retrocaruncular incision. Five out of 27 patients were reconstructed with trimmed, multiple folded, 1.0-mm-thick cross-linked ADM (MegaDerm; L&C Bio, South Korea). RESULTS: All cases reconstructed with cross-linked ADM improved clinically and radiologically without complications. The serial computed tomography findings revealed that implanted cross-linked ADM successfully covered the defect while providing a significant volumizing effect. CONCLUSIONS: This is the first study to show the efficacy of cross-linked ADM for orbital medial wall fracture reconstruction. Our strategy of orbitalization of ethmoidal sinus with stacked cross-linked ADM would be an excellent surgical option.

RESUMO

Craniomaxillofacial trauma is a challenging entity to manage effectively and often necessitates serial evaluation and treatment. A multidisciplinary team is best served to evaluate and treat these complex injury patterns with the use of necessary adjuncts, such as neuronavigation, intraoperative imaging, custom implant use, and virtual surgical planning. Complications of facial trauma can present at a spectrum of time points and manifest in a variety of manners and as such patients should be observed closely and longitudinally. Although not all complications and secondary deformities can be avoided, this article highlights some common pitfalls and our unique management strategies.

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

OBJECTIVE: For patients without dysfunctions, the main purpose of secondary correction for craniofacial fractures is restoring facial symmetry. Computer-assisted surgery techniques including virtual surgical planning and intraoperative navigation provide the help to restore the bony symmetry as much as possible. The authors retrospectively quantitatively analyzed patients who received computer-assisted secondary correction for craniofacial fractures on facial symmetry pre and postoperation. METHODS: This observational study reviewed the medical records of 17 patients requiring secondary correction for craniofacial fractures. Pre and postoperative computed tomography data were used to quantitatively analyze the changes in facial symmetry and enophthalmos. RESULT: All patients enrolled in this study showed mid-facial asymmetry but without dysfunctions except for enophthalmos, and 5 patients had bone defects in the frontal-temporal area. The corrective surgical techniques were different for each patient according to their specific condition. Virtual surgical planning with or without intraoperative navigation was performed for all patients. Compared with the preoperative condition, their facial symmetry was significantly improved. The maximum discrepancy value between the affected side and the mirrored unaffected side decreased from 8.10 ± 2.69 to 3.74 ± 2.02 mm postoperatively, and the mean discrepancy value decreased from 3.58 ± 1.29 to 1.57 ± 0.68 mm. In addition, the Enophthalmos Index decreased from 2.65 to 0.35 mm. CONCLUSION: This observational study objectively demonstrated that computer-assisted secondary correction for craniofacial fractures can significantly improve facial symmetry. And the authors recommend that virtual surgical planning and intraoperative navigation should be a must step in craniofacial fracture correction.

RESUMO

Orbital roof fractures are relatively rare facial bone fractures that usually occur in conjunction with other facial bone fractures or intracranial hematoma during high-velocity facial trauma. This study reports a patient with a significant blow-out orbital roof fracture combined with a nondisplaced frontal bone fracture and epidural hematoma at the superior aspect of unilateral frontoparietal convexity. Despite the severe superiorly-displaced fracture segment, the follow-up computed tomography scans taken 4 days after the injury showed a spontaneous reduction of blow-out orbital roof fracture. At the 1-week follow-up, the coronal image of craniofacial magnetic resonance imaging was taken, showing spontaneous realignment of orbital roof fracture and physiological evolution of cerebral contusion. In conclusion, conservative treatment can acquire the best outcome regarding cosmesis and function unless the patient requires an emergent operation for other medical conditions. This is key for successfully returning the patient's form and function.

RESUMO

Background and Objectives: The aim of this study was to study the prevalence of ocular findings in patients with orbital fractures in a tertiary center in Saudi Arabia. Materials and methods: A cross-sectional observational study was performed. The participants were patients who presented with orbital trauma to the emergency department of King Saud Medical City (Riyadh, Saudi Arabia). Subjects included those diagnosed with isolated orbital fracture using clinical evaluation and CT examination. We performed direct evaluation of ocular findings for all patients. Variables studied included age, gender, site of ocular fracture, cause of trauma, side of fracture, and ocular findings. Results: In total, 74 patients with orbital fractures were included in this study (n = 74). Of the 74 patients, 69 (93.2%) were males and only 5 patients (6.8%) were females. The age range was 8-70 years, with a median age of 27 years. The 27.5-32.6-year age group was the most affected (95.0%). The left orbital bone was involved in the majority of bone fractures 48 (64.9%). The orbital floor (n = 52, 41.9%) and lateral wall (n = 31, 25.0%) were the most prevalent sites of bone fracture among the study patients. Road traffic accidents (RTAs) were the most common causes (64.9%) of orbital fractures, followed by assaults (16.2%) and then sports injuries and falls (9.5% and 8.1%, respectively). Animal attacks were the least cause of trauma (only 1 patient, 1.4%). The occurrence of ocular findings, either alone or in combination, showed that subconjunctival hemorrhage had the highest percentage (52.0%), followed by edema (17.6%) and ecchymosis (13.6%). A statistically significant correlation was reported between the site of bone fracture and orbital findings, with r = 0.251 * and p < 0.05. Conclusions: Subconjunctival bleeding, edema, and ecchymosis were the most frequent ocular abnormalities, in that order. There were a few instances of diplopia, exophthalmos, and paresthesia. Other ocular discoveries were incredibly uncommon. The location of bone fractures was found to be significantly correlated with ocular results.
