Infection of a Nylon Foil Orbital Implant Due to Fusarium brachygibbosum and Lomentospora prolificans After Intranasal Methamphetamine Use.

The authors describe a case of nylon foil implant infection caused by Fusarium brachygibbosum , and Lomentospora prolificans following medial orbital wall fracture repair in the setting of postoperative nasal methamphetamine use. A 61-year-old male presented with OS pain and swelling after a physical assault on his face. A CT of maxillofacial bones without contrast showed a moderately comminuted fracture of the medial wall of the left orbit with depression of fracture fragments into the left ethmoid air cells. Six days after repair of the medial wall fracture, the patient returned with a new onset headache, OS pain, and swelling to the left medial canthal area. He reported snorting methamphetamine approximately 48 hours before his current presentation. CT imaging showed fat stranding and soft tissue density in the extraconal space adjacent to the left medial rectus muscle and chronic fracture deformity of lamina papyracea with approximately 4 mm of medial displacement of the fracture fragments. The patient showed little clinical improvement after 48 hours of intravenous antibiotics, which led to the removal of the nylon foil implant by a left orbitotomy. Intraoperative tissue cultures grew coagulase-negative Staphylococcus , F. brachygibbosum , and Lomentospora (Scedosporium) prolificans . The patient was subsequently transitioned to oral clindamycin 600 mg three times daily and voriconazole 200 mg two times daily. To the authors' knowledge, this is the first case report to document an association between snorted methamphetamine and a fungal infection of an orbital implant.

Ambulatory Orbital Fracture Repair: An Analysis of ER Visits After Surgery From a Multistate Study.

OBJECTIVE: To determine the 30-day postoperative emergency room (ER) visit rate following ambulatory orbital fracture repair with same-day discharge, and the causes and risk factors associated with ER visit. STUDY DESIGN: Database study. SETTING: State Ambulatory Surgery and Services Database (SASD) and State Emergency Department Database (SEDD) for California, New York, and Florida for 2011. METHODS: We identified orbital fracture repair procedures among adults from the SASD, which was linked to the SEDD to identify the incidence and causes of ER visits within 30 days. Univariate and multivariable logistic regression models were used to determine the factors associated with ER visit. RESULTS: Among 762 patients, the 30-day postoperative ER visit rate was 4.5%. Most ER visits (58.9%) occurred during the first week after surgery. The most common reasons for ER visits were related to pain, swelling, headache, dizziness, and fatigue (29.4%), followed by ophthalmologic etiologies including visual disturbances and infection of the eye (14.7%). There was no case of retrobulbar hematoma. In the multivariate analysis, patients living in Florida were at a significantly higher risk for ER visit compared to those in California (odds ratio: 4.48 [1.43-14.10], p = .010). CONCLUSION: Ambulatory orbital fracture repair appears to be safe. Common reasons for ER visit included pain, swelling, and ophthalmic symptoms. An increased risk for ER visit was seen with certain geographic regions but not with medical comorbidities or concurrent facial fractures or procedures.

Mechanisms of Development of Orbital Fractures: A Review.

PURPOSE: The purpose of this study is to review the mechanisms in the development of orbital fractures. METHODS: This is a comprehensive literature review that summarizes the mechanisms of developing orbital fractures. RESULTS: There are 3 proposed mechanisms in the development of orbital fractures, which include the buckling, hydraulic, and globe-to-wall contact mechanisms. These mechanisms, as well as patient age, causes of injuries, and periorbital anatomy, influence the extent, sites, and patterns of orbital fractures. CONCLUSION: A deeper understanding of these mechanisms helps us to detect and properly manage orbital fractures in the clinical setting.

'Frozen eye' - Post blowout fracture surgical correction - A case report.

The Rationale: "Frozen Eye" is a very uncommon sequel after treatment of orbital blowout fractures requiring implant placement. Patient Concerns: The implant may faultily impinge on the ocular and extra-ocular muscle(s), causing the abnormality in the movement of the eye. Diagnosis: We present a 56-year-old male whose ocular implant impinged on muscle, causing "frozen eye" and had an infected implant. Treatment Outcomes: The same was removed and surgically corrected. The manuscript describes the details and discusses the possible mechanism that led to the "Frozen Eye".

When the Cost of Vaping Is an Eye: A Case of an Open Globe and Superior Orbital Roof Fracture.

The authors report a penetrating orbitocerebral vape pen injury necessitating a primary enucleation and craniotomy to remove the foreign body fragments. A 31-year-old male presented with acute right vision loss after a modifiable vape pen explosion launched multiple projectile fragments into his right eye. CT revealed a deformed globe with multiple radiodense curvilinear fragments in the superior orbital roof and intracranial space. A right frontal craniotomy and orbitotomy with removal of vape pen fragments, reconstruction of the orbital roof, primary enucleation, and eyelid repair were performed in conjunction with neurosurgery. To the best of the authors' knowledge, this is the first reported penetrating globe injury from a vape pen explosion.

Work-related ocular trauma in the United States: a National Trauma Databank study.

PURPOSE: This study aims to investigate trends and risk factors associated with work-related ocular injuries occurring in adults aged 19-64 using the National Trauma Databank (NTDB). METHODS: In this retrospective, cross-sectional study, the NTDB was used to collect all patients with an ICD-9 code of work-related ocular trauma from 2007 to 2014. Demographic data and risk factors collected included age, gender, race, setting, machinery, and mechanism. Descriptive statistics, univariate, and logistic regression multivariate analyses were conducted. RESULTS: Between 2007 and 2014, 234,983 cases of work-related trauma were identified, of which 11,097 (5.7%) cases involved ocular trauma. The mean age of patients was 40.7 years (SD = 12.2), and the majority of patients (93.7%) were male. Most injuries occurred in an industrial facility, and the most common injuries were orbital floor fractures (OFFs), ocular contusions, open wounds to the adnexa, and open globe injuries (OGIs). OFFs most commonly involved a concurrent fracture of another facial or skull bone. Male gender (RR = 1.22; CI 1.09-1.38), accidental falls (RR = 1.50; CI 1.41-1.60), trauma from falling objects (RR = 1.34; CI 1.21-1.48), involvement in an unarmed fight (RR = 1.63; CI 1.39-1.91), assault by a blunt object (RR = 1.59; CI 1.31-1.91), and injury caused by animals (RR = 1.63; CI 1.30-2.02) were risk factors for OFFs. Patients with OFFs were less likely to have a concurrent OGI (RR = 0.27; CI 0.23-0.32). On the other hand, injuries occurring in industrial facilities (RR = 1.29; CI 1.11-1.51) and injuries with a loose foreign body striking the eye or adnexa (RR = 1.54; CI 1.28-1.84) were risk factors for OGI. The most common causes of work-related ocular trauma were accidental falls, motor vehicle accidents, and accidentally being struck in the eye. The mean length of hospital stay was 6.56 days (SD = 10.82); 36.7% of patients required ICU admission, and the overall in-hospital mortality rate was 2.8%. CONCLUSION: The majority of work-related ocular trauma occurred in men, most commonly in industrial locations. Accidental falls were the most common identified cause of trauma. OFF was the most common ocular injury; 80% of OFF cases involved additional facial and skull fractures. Patients with OFFs were less likely to have a concurrent OGI compared with patients without OFFs.

Multidisciplinary evaluation of orbital floor fractures: dynamic MRI outcomes.

PURPOSE: Orbital floor fractures can cause functional disorders such as limitation of ocular motility. The dysfunction of the extrinsic muscles was studied with the Hess-Lancaster test; although we expected a large percentage of inferior rectus muscle dysfunction, the results showed 52% superior rectus muscle dysfunction. METHODS: In light of these results, we began testing five patients with functional deficits evidenced by the Hess-Lancaster test with magnetic resonance imaging to assess the change in thickness of the affected muscle compared to the contralateral healthy muscle during standardized eye movements. RESULTS: This investigation showed an increase in the size of the inferior rectus muscle on the affected side during the fraction of time when the patient was asked to look up, probably due to post-traumatic fibrosis. According to our hypothesis, muscle thickness would condition the correct release of the inferior rectus muscle to such an extent that it would also influence the contraction of the superior rectus muscle, which would then be deficient. CONCLUSIONS: Based on our experience, a multidisciplinary approach and longer follow-up with thorough investigations should be considered for patients with orbital floor fractures. Furthermore, our results suggest the need for early surgical treatment, in contrast to current guidelines that aim to delay restorative surgery.

Surfboard Related Orbital and Periocular Injury.

PURPOSE: The objective of this study is to present the complexity of surfboard related orbital and periocular injuries and to discuss the different prevention aspects of such injuries. METHODS: A retrospective review was performed on surfing related orbital and periocular injuries cases in a single tertiary medical center over a period of 10 years. RESULTS: Six patients at a mean age of 34 (range 20-50) years were evaluated. All were amateur surfers. Five patients had an orbital fracture, 3 had a full thickness eyelid laceration, 3 had lacrimal drainage system damage and 3 had intraocular findings related to trauma, but no perforation of the globe was observed. Two patients had complete optic nerve avulsion or transection, 1 of them had extraocular muscle transection. Five patients underwent surgery and 2 required an additional surgical intervention. At the end of follow-up, 3 patients had an unrepairable lacrimal drainage damage, 2 had a malposition of an eyelid, 2 eyes remained blind, 1 patient had a hypoglobus, and 1 had hypoesthesia in distribution of infraorbital nerve. CONCLUSIONS: Surfboard related orbital injuries may cause a severe orbital injury, which may debilitate and disable a previously active and healthy group of young people. Hence, protective gear wear should be more vigorously encouraged as already been done in other sports.

Comparison of Blowout Fracture Sites Observed in Young and Elderly East Asians.

ABSTRACT: The purpose of this study was to investigate the distribution of blowout fracture sites among age groups and compare clinical factors that can affect the fracture site. The authors reviewed 330 cases of blowout fracture surgeries and included 226 eyes of 226 patients aged between 20 and 29 years and between 50 and 59 years who underwent blowout fracture reconstruction between January 2017 and December 2020, in the Department of Ophthalmology at Korea University Hospital.Medical records including patient demography, trauma etiology, and preoperative computed tomography image were evaluated. Ethmoidal cell septa and fracture site position were compared between the 2 age groups. The causes of injury were categorized into 3 groups: focal trauma, gross trauma, and other causes. Orbital floor fracture was the most common type (40.00%) in the young group, followed by medial wall fracture (25.33%). in contrast, medial wall fracture accounted for the largest proportion (42.11%) in the older group, and orbital floor fracture accounted for only 26.67%. The major cause of blowout fracture in young patients was focal trauma, whereas gross trauma was the most common cause in the older group. The number of ethmoidal cells was 4.19 ±â€Š0.831 (2-6) in the young group and 3.91 ±â€Š1.022 (2-6) in the old group (P  < 0.05). Distribution of blowout fracture site differed between age groups, and these differences can be explained by cause of injury and number of ethmoidal cells.

Analysis of Patients With Blowout Fracture Caused by Baseball Trauma.

ABSTRACT: The purpose of this study was to investigate the characteristics of blowout fractures caused by baseball trauma. The authors reviewed 337 cases of blowout fracture surgeries and included 330 eyes of 330 patients who underwent blowout fracture reconstruction between January 2017 and December 2020, in the Department of Ophthalmology at Korea university Hospital.Medical records including patient demography, trauma etiology, accompanied ocular disease, and preoperative computed tomography images were evaluated. Patients were categorized into 2 groups: a group with blowout fracture caused by baseball trauma and another group with trauma due to other causes. Two-wall blowout fracture (orbital floor fracture and medial wall fracture) was most common (63.16%) in the baseball group, followed by medial wall fracture (21.05%). In contrast, orbital floor fracture accounted for the largest proportion (42.11%) among other causes, and 2-wall blowout fracture accounted for the second largest proportion (31.83%). The most common accompanied ocular disease was traumatic hyphema and traumatic iridocyclitis (36.84%) in the baseball blowout fracture group. in contrast, subconjunctival hemorrhage was the most common ocular disease in the other-causes group (16.08%). The frequency of traumatic hyphema and irido-cyclitis was significantly different among the 2 groups (P  < 0.05). Distribution of blowout fracture sites and frequent ocular disease differed between baseball blowout fracture patients and other-cause blowout fracture patients.

Orbital fractures. / Orbitafrakturer.

Orbital fractures can occur as a result of direct trauma to the eye region or surrounding facial bones. The fractures can lead to significant functional impairment and cosmetic changes. Surgical treatment of orbital fractures aims to reconstruct the bony anatomy and restore the orbit's original volume. This clinical review article looks at the key factors regarding orbital fractures.

Blowout Fracture Assessment Based on Computed Tomography and Endoscopy: The Effectiveness of Endoscopy for Fracture Repair.

ABSTRACT: The purpose of this study was to compare the configuration of blowout fracture observed through orbital computed tomography (CT) and endoscopy, then present the effectiveness of using an endoscope in reconstruction surgery of blowout fracture. We retrospectively reviewed the clinical records of 337 patients who underwent reconstruction surgery of blowout fracture between January 2017 and December 2020 in the Department of Ophthalmology at Korea University Guro Hospital. The patients were categorized into 3 groups based on preoperative CT findings as follows: combined orbital medial and floor wall fractures, trapdoor fractures, and large blowout fractures. The images obtained through CT and endoscopy were compared among the 3 groups. Endoscopy helped identify herniated soft tissue and posterior fracture margins, and it also provides better magnification and a brighter view of the posterior aspects of the fracture site. Furthermore, endoscopy can also provide educational opportunities to visualize the fracture site and help trainees understand the surgical procedure approach or orbital anatomy. Based on our results, we suggest using an endoscope during blowout fracture surgery as an effective approach to reduce postoperative complications due to endoscopy's advantages in clear visualization of the fracture site during operation.

Orbital floor fractures: epidemiology and outcomes of 1594 reconstructions.

OBJECTIVE: The aim of this study was to retrospectively review the midface and orbital floor fractures treated at our institution with regard to epidemiological aspects, surgical treatment options and postoperative complications and discuss this data with the current literature. STUDY DESIGN: One thousand five hundred and ninety-four patients with midface and orbital fractures treated at the Department of Oral, Cranio-Maxillofacial and Facial Plastic Surgery of the Goethe University Hospital in Frankfurt (Germany) between 2007 and 2017 were retrospectively reviewed. The patients were evaluated by age, gender, etiology, fracture pattern, defect size, surgical treatment and complications. RESULTS: The average patient age was 46.2 (± 20.8). Most fractures (37.5%) occurred in the age between 16 and 35. Seventy-two percent of patients were male while 28% were female. The most common cause of injury was physical assault (32.0%) followed by falls (30.8%) and traffic accidents (17.0%). The average orbital wall defect size was 297.9 mm2 (± 190.8 mm2). For orbital floor reconstruction polydioxanone sheets (0.15 mm 38.3%, 0.25 mm 36.2%, 0.5 mm 2.8%) were mainly used, followed by titanium meshes (11.5%). Reconstructions with the 0.15 mm polydioxanone sheets showed the least complications (p < 0.01, r = 0.15). Eighteen percent of patients who showed persistent symptoms and post-operative complications: 12.9% suffered from persistent hypoesthesia, 4.4% suffered from post-operative diplopia and 3.9% showed intra-orbital hematoma. CONCLUSION: Results of the clinical outcome in our patients show that 0.15 mm resorbable polydioxanone sheets leads to significantly less post-operative complications for orbital floor defects even for defects beyond the recommended 200 mm2.

Pathophysiologic Review of Blow-Out Fracture and Blow-Out Fracture Extended to Subarachnoid Space Due to Air Gun Injury.

ABSTRACT: Blow-out fracture is usually caused by direct traumatic events in the periorbital area. But in this case, the authors introduce a case in which the medial orbital wall was fractured directly through the medial rectus muscle by high pressure air gun.A 38-year-old man was injured in his right periorbital area after being hit by high pressure air gun. He had mild ecchymosis and subconjunctival hemorrhage. He had a normal light reflex and intraocular pressure of 14 mm Hg. A facial computed tomography scan confirmed a blow-out fracture of the medial orbital floor with multiple extensive subcutaneous emphysema in the right hemifacial area. Free air was also seen near the basal cistern and Sylvian fissure, indicating a pneumocephalus. The operation was performed after swelling and emphysema were subsided. Intraoperative, medial rectus muscle was damaged. After the operation, no abnormal findings were observed in the ophthalmic examination. Also, the free air findings, which were observed in preoperative x-ray, have disappeared.This case is a rare case in which an orbital wall has been fractured directly through the medial rectus muscle due to an air gun injury. Therefore, we should always kept in mind that blow-out fractures can occur even with unusual mechanisms.

Detection and Referral of Orbital and Ocular Injuries Associated With Intimate Partner Violence Following an Educational and Screening Initiative in an Emergency Department.

IMPORTANCE: Intimate partner violence (IPV) is a substantial cause of morbidity and mortality in the US. Previous studies indicate gaps in identifying and referring female patients with IPV-associated orbital and ocular injuries to ancillary services. OBJECTIVE: To determine the number of IPV-associated orbital floor fractures, zygomaticomaxillary complex (ZMC) fractures, and ruptured globes referred to ancillary services in adult female patients following an educational and screening intervention to health care professionals. DESIGN, SETTING, AND PARTICIPANTS: This single-center retrospective quality improvement analysis examined electronic medical records of adult female patients seen in a single level 1 trauma center emergency department and ophthalmology clinic between January 2015 and February 2019, after the initiative began. Female adults who sustained orbital floor fractures, ZMC fractures, or ruptured globes were included. Preinitiative data were previously collected between January 1995 and January 2015 on adult female patients and published. Data analysis for this study occurred from May 2020 to September 2020. INTERVENTIONS: A 2-part, ongoing initiative began January 2015. First, enhancement of IPV screening protocols in the emergency department was conducted. Second, an educational campaign on IPV injury patterns was presented to residents and faculty in ophthalmology, emergency, otolaryngology, and trauma departments. MAIN OUTCOMES AND MEASURES: Comparison of ancillary service involvement preinitiative (January 1995 to January 2015) and postinitiative (January 2015 to February 2019). RESULTS: A total of 216 adult female patients (mean [SD] age, 55.0 [22.7] years; age range, 18-99 years) sustained orbital floor or ZMC fractures postinitiative. A total of 22 of 216 (10.2%) sustained fractures from IPV compared with 31 of 405 (7.6%) preinitiative (95% CI, -2.2% to 7.3%; P = .28). Documented social work referrals (11 of 31 preinitiative vs 20 of 22 postinitiative; difference, 55% [95% CI, 35%-76%]; P < .001), homegoing safety assessments (1 of 31 preinitiative vs 18 of 22 postinitiative; difference, 79% [95% CI, 61%-96%]; P < .001), and law enforcement involvement (7 of 21 preinitiative vs 16 of 22 postinitiative; difference, 50% [95% CI, 26%-74%]; P < .001) were higher in patients who presented after the initiative with orbital floor and ZMC fractures. A total of 51 adult female patients (mean [SD] age, 57.7 [20.8] years; age range 20-93 years) sustained ruptured globes postinitiative. A total of 5 of 51 patients (9.8%) sustained injury due to IPV postinitiative, compared with 5 of 141 (3.5%) preinitiative (95% patients, -2.5% to 15.0%; P = .08). CONCLUSIONS AND RELEVANCE: Following the start of the initiative, referral patterns of adult female patients with IPV-associated orbital fractures improved. Targeted IPV screening of patients with orbital and ocular injuries is essential for effective intervention.

The Association of Zygomaticomaxillary Complex Fractures with Naso-Orbitoethmoid Fractures in Pediatric Populations.

BACKGROUND: Naso-orbitoethmoid fractures associated with ipsilateral zygomaticomaxillary complex fractures are more challenging injuries than zygomaticomaxillary complex fractures alone. However, there is a paucity of information on this complex fracture pattern in the pediatric population. This study investigated the cause, treatment, and outcomes of combined zygomaticomaxillary complex and naso-orbitoethmoid fractures versus isolated zygomaticomaxillary complex fractures in pediatric patients. METHODS: This was a 25-year retrospective cohort study of pediatric patients who presented to a single institution with zygomaticomaxillary complex fractures. Baseline patient demographics and clinical information, and concomitant injuries, treatment/operative management, and postoperative complications/deformities were recorded and compared between patients with combined zygomaticomaxillary complex and naso-orbitoethmoid fractures and patients with isolated zygomaticomaxillary complex fractures. RESULTS: Forty-nine patients were identified to have had zygomaticomaxillary complex fractures in the authors' 25-year study period, of whom 46 had adequate clinical documentation and follow-up. Seventeen patients had combined zygomaticomaxillary complex-naso-orbitoethmoid fractures, of whom six had panfacial fractures. Both patient groups (zygomaticomaxillary complex only and combined zygomaticomaxillary complex-naso-orbitoethmoid fractures) were similar in terms of demographics. However, a significantly greater proportion of combined fracture patients experienced postoperative complications compared to isolated zygomaticomaxillary complex fracture patients, even after excluding those with panfacial fractures (87.5 percent versus 35.3 percent; p < 0.001). Enophthalmos (37.5 percent) and midface growth restriction (37.5 percent) were the two most common complications/deformities in all combined fracture patients. CONCLUSIONS: High-impact trauma can lead to zygomaticomaxillary complex fractures with associated naso-orbitoethmoid fractures in children. This injury pattern was found to cause significantly greater postoperative morbidity than isolated zygomaticomaxillary complex fractures alone. Thus, pediatric patients presenting with this complex facial fracture pattern should be closely monitored. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

Traumatic dislocation of the eye into the maxillary sinus: Case report and literature review.

Traumatic dislocation of the eye is usually encountered in high-energy injuries. These include traffic accidents, accidents at work, sporting accidents, falling from a height, impact of the hooves or horns of animals, gunshot injuries, and physical assault. Such incidents are accompanied by facial soft tissue damage and injuries to the facial skeleton, especially the orbit, and can be associated with varying degrees of dislocation of the eye. We describe a rare case of non-fatal traumatic eye dislocation into the maxillary sinus, coupled with an orbital fracture resulting from a physical assault on a 63-year-old woman. The cause of death was asphyxiation due to manual strangulation and mechanical asphyxia. Even though dislocations of the eye are relatively rare, forensic pathologists should be aware of such injuries to correct assessment of injury mechanism. The available literature regarding eye dislocation is summarized, and the forensic issues applicable to the assessment of such cases are reviewed.

Facial Fractures Related to Soccer.

ABSTRACT: Soccer is one of the most popular sports in the world. Despite the concept that soccer is not a violent game, it can lead to several injuries in amateur and professional settings, including facial fractures. Previous studies of facial fractures in soccer were all retrospective and, to date, no prospective studies are available in the literature.The authors performed a comprehensive literature search using the terms "soccer" AND "facial fracture" OR "craniofacial fracture" and "football" AND "facial fracture" OR "craniofacial fracture" and retrieved 693 articles. After applying inclusion and exclusion criteria, 11 articles were included in the present study.A total of 647 patients had suffered facial trauma, with a male-to-female ratio of 63.7:1. The patients' mean age was 27.3 years.The articles reported 670 fractures as follows: 219 (32.7%) in the zygoma, 197 (29.4%) in the nasal bone, 153 (23.6%) in the mandibula, 54 (8.0%) in the orbital wall, 12 (1.8%) in the frontal sinus, 10 (1.5%) in the alveolar bone, 3 (0.4%) in the maxilla, 3 (0.4%) in a Le Fort pattern, and 1 (0.1%) in a naso-orbito-ethmoid (NOE) pattern.Sports are a frequent cause of maxillofacial trauma and are responsible for 9.2% to 33.2% of such injuries. Soccer is a contact sport more associated with lower-limb injuries, but with a significant rate of facial fractures. As soccer is a popular sport played without facial protection and involving high-intensity movements and contact, the prevention of facial fractures related to this sport is crucial to improve the players' safety.

Functional recovery time after facial fractures: characteristics and associated factors in a sample of patients from southern Brazil.

Understanding the cause, severity, and elapsed time for the restoration of the functions of maxillofacial injuries can contribute to the establishment of clinical priorities aiming at effective treatment and further prevention of facial trauma. The objective of this study was to understand the factors associated with the restoration of mastication, ocular, and nasal functions in the face of trauma victims, estimating their recovery time after surgical treatment. We analyzed 114 medical records of patients treated at the Hospital Montenegro, who attended follow-up consultations for up to 180 days. For analysis of the recovery time, we performed survival analysis, followed by COX analysis. We observed that half of the patients recovered their functions within 20 days. The average time for recovery from trauma in the zygomatic-orbital-malar-nasal complex was 11 days, and in the maxillary-mandibular complex, 21 days (HR: 1.5 [0.99 2.3], p = 0.055). Although functional reestablishment has reached high rates after the surgical approach, it is necessary to analyze the failing cases, as well as the economic impacts and the prevention strategies associated with facial trauma, to improve the service to the population.

Complex Fistula Formations After Orbital Fracture Repair With Teflon: A Review of 3 Case Reports.

ABSTRACT: The authors present 3 unique cases of complex fistula formations because of orbital fracture repair with a Teflon (polytetrafluroethylene) implant. A 26-year-old man presented with dacryocystitis and a cutaneous fistula 8 years after left orbital floor and medial wall fracture repair with a Teflon implant. A 46-year-old woman suffered orbital trauma after a motor vehicle accident as a teenager and the fracture was repaired with Teflon implant. Thirty-two years later, she presented with lower eyelid fistula, ectropion, and retraction. A 65-year-old woman also previously had Teflon implants for the repair of her left inferior and lateral orbital rim after a motor vehicle accident. Twenty-five years later, she presented with chronic infections involving the repaired areas, as well as left lower lid ectropion and fistula formation. The woven material nature of Teflon acted as a nidus for infection, inflammation, and led to complex cutaneous fistula formations in these patients.
