Epidemiological Study on Ocular Trauma and Associated Co-Morbidity at Tertiary Health Care Hospital

Aims: To classify and find out the incidence of ocular injury effects and extraocular associates. Methods and Materials: This eight-month observational study was conducted between 2017 and 2018 recruiting 111 eyes of 101 patients reporting to ophthalmology outpatient and emergency medicine departments. Results: The demographic profile is composed of 82 (81.18%) males and 19 (18.81%) females with a mean presenting age of 33.45 and 33.57 years in males and females respectively ranging from 3 to 82 years. Sixty four (57.65%) right and 47 (42.34%) left eyes studied. Closed globe injuries accounted for 95 (85.56%) and open globe injuries were found in 16 (14.41%) eyes. Mode of injuries classified as RTA 37 (33.33%), RTA Self fall 26 (23.42%), metal-induced trauma in 9 (8.10%) and exposure to vegetative matter in 9 (8.10%), self fall at home/work in 6 (5.40%), assault in 4 (2.6%), sports-related injuries in 3 (2.7%), bull gore injuries in 3 (2.7%) and explosion injuries in 3 (2.7%) eyes. RTA and RTA self fall showed the highest relative risk and odds ratio among males compared to females. The relative risk ratio and odds ratio for RTA in males showed 0.63 and 0.31 respectively. Anterior segment injury effects were observed in all eyes and 21 (18.91%) eyes with posterior segment involvement. The associated facio-maxillary injury was seen in 58 (52.25%) eyes, orbital wall fractures in 52 (46.85%), and head injury in 26 (23.42%) eyes. Thirty (35.14%) eyes required imaging for further evaluation, of which 32 (31.68%) underwent computed tomography and 2 (1.99%) eyes subjected to magnetic resonance imaging. Fifty-three (52.47%) eyes were managed surgically, 25 (24.75%) conservatively and 23 (22.77%) medically. Conclusion: This study analysis concludes that closed globe injury is the most common ocular trauma. In middle-aged male patients, RTA-induced injuries were commonly prevalent. The most frequently associated co-morbidities were facio-maxillary trauma, lateral orbital wall fractures, and subconjunctival hemorrhage. Maximum eyes required surgical management while computed tomography provided a conventional mode of imaging. The multi-departmental management approach is essential for achieving a good medical and surgical outcome.

The Incidence of Traumatic Optic Neuropathy Associated With Subtypes of Orbital Wall Fracture.

Traumatic optic neuropathy (TON) is a rare disease but leaves critical sequelae to patient. Purpose of this study is to evaluate the incidence of TON in each orbital wall fracture. Retrospective review of 2629 patients with orbital wall fracture was performed in from January 2010 to March 2019, based on diagnostic code, Korean Standard Classification of Diseases, 7th Revision. The orbital wall fractures were divided into 4 subtypes: superior, medial, inferior, and lateral wall. Incidence of TON is analyzed according to subtypes, single and multiple wall fracture. Among 2629 patients with orbital wall fractures, 27 patients were diagnosed with TON with an incidence of 1.02%. In single wall fracture, only lateral wall showed significantly high TON incidence, which only zygomatic fracture was included in single lateral wall fracture. In multiple wall fracture, it was statistically significant in the superior wall. Fracture on lateral and superior orbital wall showed a tendency to increase the incidence of TON. Based on the above results, radiologic evaluation and physical examination is necessary for patient who has lateral and superior orbital wall fracture.

Predictors and Significance of Orbital Fracture in Traumatic Brain Injury

Background and purpose: Orbital manifestation in traumatic brain injury though uncommon, is one of the major complications of traumatic brain injury that has to be addressed judiciously to prevent permanent visual loss.
 Material and Methods: 211 patients who underwent CT for traumatic brain injury in between September to December 2019 were prospectively examined for the orbital manifestation. Patients who had undergone CT head including orbit with 3D face RECON were only included in our study to remove the bias between fracture line and suture in plain CT scan. CT imaging was evaluated to identify and subtype the orbital fracture.
 Results: Total number of patients was 28, with mean age of 33.82 (SD 17.15) years. Majority of the patients were male which accounted 79% of sample size. There was 78% mild head injury followed by 18% and 4% moderate and severe head injury respectively. The most common type involved among all were blow out fracture and lateral orbital wall fracture. Clinically vision was abnormally around 21% of the cases, abnormal papillary reaction was seen in 25% of the cases around 93% of the cases had raccoon eye at the time of presentation. There was proptosis in around 14% of the patients and subconjunctival hemorrhage was seen in around 93% of the cases. Around 79% of the patients had intact vision at the time of presentation and 3.6% of the patients improved their vision during the course of treatment. Complete globe disruption who required evisceration of the eyeball was 10.7% and those who had abnormal vision at the time of presentation, 7.1% that did not improve their vision.
 Conclusions: orbital manifestations with either type of orbital fracture in traumatic brain injury are useful for the prediction of severity of orbital injury and its clinical outcome. This helps to identify patients in high risk and start early treatment to prevent permanent visual loss.

Facial Fracture Patterns Associated with Traumatic Optic Neuropathy.

Traumatic optic neuropathy (TON) is rare. The heterogeneity of injury patterns and patient condition on presentation makes diagnosis difficult. Fracture patterns associated with TON have never been evaluated. Retrospective review of 42 patients diagnosed with TON at the R. Adams Cowley Shock Trauma Center from May 1998 to August 2010 was performed. Thirty-three patients met criteria for study inclusion of fracture patterns. Additional variables measured included patient demographics and mechanism. Cluster analysis was used to form homogenous groups of patients based on different fracture patterns. Fracture frequency was analyzed by group and study population. Visual depiction of fracture patterns was created for each group. Cluster analysis of fracture patterns yielded five common "groups" or fracture patterns among the study population. Group 1 ( n = 3, 9%) revealed contralateral lateral orbital wall (100%), zygoma (67%), and nasal bone (67%) fractures. Group 2 ( n = 7, 21%) demonstrated fractures of the frontal bone (86%), nasal bones (71%), and ipsilateral orbital roof (57%). Group 3 ( n = 14, 43%) involved fractures of the ipsilateral zygoma (100%), lateral orbital wall (29%), as well as frontal and nasal bones (21% each). Group 4 ( n = 5, 15%) consisted of mid- and upper-face fractures; 100% fractured the ipsilateral orbital floor, medial and lateral walls, maxilla, and zygoma; 80% fractured the orbital roof and bilateral zygoma. Group 5 ( n = 4, 12%) was characterized by fractures of the ipsilateral orbital floor, medial and lateral orbital walls (75% each), and orbital roof (50%). A notably high 15 of 33 patients (45%) sustained penetrating trauma. Our study demonstrates five fracture pattern groups associated with TON. Zygomatic, frontal, nasal, and orbital fractures were the most common. Fractures with a combination of frontal, nasal, and orbital fractures are particularly concerning and warrant close attention to the eye.

An aggressive and fatal craniofacial group A Streptococcus infection resulting from a minimally displaced orbital floor fracture

While sharp, penetrating trauma is often associated with group A Streptococcus (GAS) infections and subsequent necrotizing fasciitis (NF) and streptococcal toxic shock syndrome (STSS), there are scant reports in the oral and maxillofacial surgery literature regarding blunt, non-penetrating trauma in association with these conditions. With a clinical course that initially appears relatively benign following blunt trauma, NF can progress swiftly through the fascial planes and may quickly become life-threatening if the oral and maxillofacial surgeon fails to recognize some of the critical pathognomonic signs. The case of a 64-year-old female who suffered a ground-level mechanical fall with a minimally displaced lateral orbital wall fracture is reported here. This seemingly benign, non-penetrating injury subsequently developed into rapidly progressive, fatal NF and STSS. This case is used to highlight the necessity for early detection of NF and STSS prior to rapid clinical decline, as these scenarios, particularly bilateral peri-orbital NF with resulting mortality, have been reported infrequently following blunt, craniofacial trauma in the literature related to this specialty.

Clinical observation on the improved reductive surgery for the treatment of zygomatic complex fractures

Objective To observe the clinical effect of improved reductive surgery for zygomatic complex fracture. Methods Thirty-two patients with zygomatic complex fractures were given zygomatic arch and lateral orbital wall fracture CT 3D reconstruction before operation to display position of fracture. The skin incision was made along the lower eyelid margin and extended about 15 mm outward canthus. Then the periosteotomy was done and the periosteum was separated to the back of zygomatic arch. The fracture was fixed with micro titanium nail plate to restore the normal anatomical position of zygomatic arch and to reset orbital margin completely. Results Two weeks after the operation, the soft tissue swelling of the orbital region faded. The deformity was completely corrected, and the opening movement of mouth was improved obviously compared with that before the operation. Three months after the surgery, the zygomatic appearance was symmetrical in 32 cases, with no obvious differences in appearance. Mouth opening degree was higher than 40 mm.The two eyeballs were symmetrical. Conclusion The improved subciliary approach combined with micro titanium nail and plate for zygomatic complex fracture has good effect. Key words: Fractures, traumatic; Zygomatic complex; Reductive surgery, modified; Incision

Diagnostic performance of isolated orbital CT scan for assessment of globe rupture in acute blunt facial trauma

ObjectivesWe determine the diagnostic performance of emergent orbital computed tomography (CT) scans for assessing globe rupture in patients with blunt facial trauma. MethodsWe performed a retrospective cohort study based on prospectively collected trauma registry and acute care surveillance data in a tertiary-care hospital. Patients aged at least 18 years who underwent isolated orbital CT scanning for assessing potential ocular trauma were examined. Analyses were performed to evaluate the magnitude of agreement between diagnosis by CT scanning and ophthalmic assessment, including globe rupture. ResultsOur study cohort comprised 136 patients, 30% of whom (41 patients) sustained orbital wall fractures. Concordance for orbital CT diagnosis and the ophthalmic assessment of globe rupture was substantial (k=0.708). The relative risk of globe rupture was 0.692 (95% confidence interval (CI): 0.054–8.849) for superior wall fractures, 0.459 (95% CI: 0.152–1.389) for inferior wall fractures, 2.286 (95% CI: 1.062–4.919) for lateral wall fractures, and 0.637 (95% CI: 0.215–1.886) for medial wall fractures. According to multivariate analysis, lateral wall fractures were an independent risk factor for globe ruptures (adjusted odds ratio (OR)=12.01, P=0.011), and medial or inferior wall fracture was a protective factor (adjusted OR=0.14, P=0.012). In the stratified analysis of diagnostic performance of CT scan, specificity was highest among patients with orbital wall fractures (97.2%), followed by negative predictive volume (NPV, 97%), and accuracy (95.1%). ConclusionAmong patients with blunt facial trauma who underwent isolated orbital CT scanning as part of ocular trauma assessment, the diagnostic performance of CT in detecting globe rupture is more accurate in patients with orbital wall fractures. Nevertheless, isolated orbital CT alone does not have a sufficiently high diagnostic performance to be reliable to rule out all globe ruptures. Lateral orbital wall fractures in blunt facial trauma patients, in particular, should prompt thorough evaluation by an ophthalmologist.

Acceso retrocaruncular para la reconstrucción de la pared medial de la órbita

ObjectiveTo present a retrospective analysis of the use of retrocaruncular approach to access medial orbital wall reconstruction. Additionally, the technique for performing this access is described. Material and methodThe sample for this study was chosen from the population of patients referred to the Maxillofacial Surgery Service at the Hospital Clínico Mutual de Seguridad C.Ch.C (Santiago, Chile) for the treatment of orbital fractures between 1st of January 2011 and 31st of December 2014. Subjects eligible for study inclusion had age ≥18, either isolated medial orbital wall fractures or combined with floor fractures, uni or bilateral, with surgical indication, accessed with retrocaruncular approach and 6 month of follow up at least. Exclusion criteria: roof and/or lateral orbital wall fractures. ResultsBetween January 2011 and December 2014, a total of 168 orbits were treat. 27 orbits with medial wall fractures were accessed with retrocaruncular approach with transconjunctival extension and lateral canthotomy and were included in this study. Of them, 6 were pure medial wall fractures and 21 combined with floor fractures. Except for one case that required delayed reconstruction with customized orbital implant, all orbital reconstructions were successful in the first surgery. Except for a patient who developed a conjunctival granuloma in relation to the caruncle, no patients had complications related to retrocaruncular access. ConclusionesThe retrocaruncular approach presented allows asafe, wide and direct access for repairing medial orbital wall fractures with optimal aesthetics results and minimal functional complications.

Lateral Orbital Wall Fracture as a Mechanism of Blow-out Fracture in a Patient With Extensive Pneumatization of the Sphenoid Bone

We report a patient with a lateral orbital wall fracture that occurred as a result of a blow-out fracture. The patient has extensive pneumatization of the sphenoid sinus, and the air extends into the lateral orbital wall. It makes the lateral orbital wall much thinner unusually, being more vulnerable to a sudden increase in intraorbital pressure. Pure blow-out fracture of the lateral orbital wall has not been reported in the medical literature. Therefore, this is the first case report of a lateral orbital wall fracture occurring as a blow-out mechanism.

Ratio of Simple versus Comminuted Lateral Wall Fractures of the Orbit

Reduction of a fracture may be relatively easy with a simple, noncomminuted fracture along the zygomaticofrontal suture, zygomaticomaxillary buttress, or the inferior rim of the orbit. When one or more of these key landmarks is comminuted, it becomes more important to confirm that the fracture commonly seen between the greater wing of the sphenoid and the zygoma is properly repositioned. The zygomaticosphenoidal suture is an excellent landmark with a simple lateral orbital wall fracture (LOWF), but it may not be reliable in patients with a comminuted fracture. The purpose of this study is to determine the frequency that the lateral orbital wall (LOW) is a reliable landmark in the reduction of a zygoma fracture by determining the ratio between simple versus comminuted LOWF. To identify 100 patients with a LOWF, the authors reviewed consecutive midface computed tomography images of 877 patients performed over a 25-month period from one of our city's primary Level I trauma and teaching hospitals. A total of 121 LOWF were identified in 100 patients. In 60.3% of cases the facture was a simple, noncomminuted LOWF. In 39.7% of cases the fracture was comminuted (p = 0.023). Simple LOWF are significantly more common than comminuted fractures. In 39.7% of fractures the LOW is comminuted. This suggests that there are many fractures in which other modalities may be much more important to use to confirm the proper reduction of the zygoma.

An unusual case of intraorbital foreign body and its management

A 36-year-old aboriginal female presented following an assault with a wooden fence paling. Examination revealed a wooden object protruding lateral to the left eyebrow. CT scan showed a blow-in fracture of lateral orbital wall and a hypodense foreign body causing indentation of the globe and stretching of the optic nerve. The case was managed successfully with complete recovery of the visual acuity on day 1 post-surgery. This case highlights the importance of prompt removal of large lateral wooden intraorbital foreign body to achieve an excellent visual outcome.

Delayed Repair of Lateral Orbital Wall and Orbital Floor Fracture

Timing of surgical management of facial fractures may differ from the current standard when an associated severe ophthalmologic injury exists; this may necessitate a delay in repair to protect the patient's vision. We set out to demonstrate that good functional and aesthetic outcomes can be achieved in cases where zygoma bone fracture repair had to be delayed for more than 21 days after injury with a specific surgical plan.Using the electronic database from Montreal General Hospital, a level I trauma center, a retrospective review of all facial fractures occurring from 1994 to 2009 was performed. Our review returned a total of 22,727 trauma patients admitted to Montreal General Hospital. Of these, 2672 sustained 1 or more facial fractures. Among the facial trauma patients, 945 patients' injuries included a zygoma fracture, 324 (35.3%) of which were managed operatively. Seven cases had their surgery delayed for more than 21 days after injury, 2 of which were managed using simple osteotomies and plate fixations, without the need for bone grafts. Both patients demonstrated a satisfactory outcome with improvement relative to their preoperative status. We provide a detailed description of our most recent case of a 73-year-old woman in whom the surgical repair of the lateral orbital rim and orbital floor was delayed for 10 weeks to allow healing of her associated traumatic retinal detachment.For patients with associated ocular injuries who cannot undergo orbital fracture repair within 21 days of the trauma, delayed surgery may still result in an acceptable aesthetic result.

Transient pseudo-Duane syndrome after lateral orbital trauma

Duane syndrome is a dysinnervation disorder that frequently involves secondary anomalous eye movement, in particular, ocular retraction and the narrowing of the palpebral fissure on the adduction. Pseudo-Duane syndrome is caused by a mechanical restriction that produces clinical findings similar to those of Duane syndrome. Most patients with pseudo-Duane syndrome have restrictive pathologies on the medial side of the globe, such as entrapment of the medial rectus muscle. We report the case of a 44-year-old man with pseudo-Duane syndrome in whom we identified a lateral orbital wall fracture and entrapment of the soft tissue surrounding the lateral rectus muscle by computed tomography. To the best of our knowledge, this etiology of pseudo-Duane syndrome has not been previously reported.

顔面骨骨折１０４例の臨床統計的検討

One hundred and four cases (79 males and 25 females) with facial bone fractures treated at Himeji Medical Center between June 2000 and May 2004 were reviewed. Patient ages ranged from 2 to 78 years with an average of 30.8 years. There were 127 sites of facial bone fractures, which were the nasal bone (54 cases), the orbit (37 cases), the maxilla (11 cases), the mandible (6 cases), the zygoma (17 cases), and the frontal bone (2 cases). Orbital bone fractures consisted of 19 orbital floor fractures, 16 medial orbital wall fractures, and 2 lateral orbital wall fractures with 4 cases showing combined fractures of the floor and median wall. The causes of fractures were 1) traffic accidents (32.3%), 2) accidents or falls (24.4%), 3) sports (23.6%), and 4) violence or fights (19.7%).Surgical treatments were performed for 61 (48.0%) of 127 sites and the remaining cases were treated conservatively. There were 32 cases (59.3%) undergoing reduction of the nasal bone, 19 cases (51.4%) reduction of the orbit, one case (9.1%) reduction of the maxilla, 6 cases (100%) reduction of the mandible, and 3 cases (17.6%) reduction of the zygoma. Nasal fractures were reduced under local anesthesia in 29 (90.6%) patients. We used the transorbital approach with sub-ciliary incision for 14 cases of the orbital floor fracture and the endonasal approach with an endoscope for 5 cases of medial orbital wall fracture. Eleven (84.6%) of 13 orbital floor fractures needed orbital floor reconstruction with iliac bone grafts.Seventeen cases (16.3%) had additional fracture sites or injuries in the body and needed treatment provided by staff from several different departments. For 6 cases, the facial bone fracture was repaired at the same time as other orthopedic procedures under general anesthesia.

Intrarater Reliability in the Ultrasound Diagnosis of Medial and Lateral Orbital Wall Fractures With a Curved Array Transducer

The aims of the study were to document the effectiveness of ultrasound (US) in diagnosing orbital wall fractures when compared with computed tomography (CT) and to measure the intraobserver reliability of US using a curved array transducer. From December 2003 to March 2004, 13 patients with the clinical diagnosis of an orbital trauma were investigated prospectively by CT (reference) and 2 US investigators. Both orbits were investigated. Sensitivity, specificity, accuracy, and positive and negative predictive value were calculated. The statistical difference between the 2 US investigators was calculated by a chi-square test. The interrater reliability was calculated using the lambda coefficient. Values below 0.4 represent poor reliability, between 0.4 and 0.75 represent fair to good reliability, and a score > 0.75 is graded as excellent reliability. The comparison of the results of the 2 US investigators by the chi-square test showed P values of .385 for the medial orbital wall and .638 for the lateral orbital wall, which shows no significant difference. The lambda-value for the investigation of the medial orbital wall reached 0.429, 0.714, and 0.750. The lambda-value for the investigation of the lateral orbital wall yielded 0.647, 0.750, and 0.882. These values show a good and excellent inter-rater reliability. The US investigation does not yet reach the diagnostic quality of CT. US could be a helpful diagnostic imaging tool in cases with clear clinical symptoms. The results of the current study and the previously published results imply that US has the potential to reach the same diagnostic quality as CT in the future, but further studies must be performed to improve the diagnostic quality of the method.

Effectiveness of ultrasonography in determining medial and lateral orbital wall fractures with a curved-array scanner

Purpose The purpose of the study was to evaluate the diagnostic value of ultrasonography to determine medial and lateral orbital wall fractures. Materials and methods Sixty-two patients with the clinical diagnosis of an orbital trauma underwent coronal computed tomography (CCT) and ultrasonographic investigation (US). Inclusion criteria were clinically suspected orbital injuries defined by reduced bulbus motility, diplopia, or additional traumatic injuries of the orbit or the globe. US and CCT were used as imaging diagnostic methods. Results Ultrasonography showed a sensitivity of 56%, a specificity of 95%, and an accuracy of 88% at the medial orbital rim. Regarding the lateral orbital rim, ultrasonography showed a sensitivity of 92%, a specificity of 88%, and an accuracy of 90% using CCT as a reference method. Conclusion Ultrasonography with a curved-array scanner seems to be a valuable method in the detection of lateral orbital wall fractures. Further studies have to be done to improve sensitivity in the interpretation of medial orbital wall fractures.

Repair of zygomaticomalar complex fractures. The Swiss method.

The zygomaticomalar complex fracture, also known as the trimalar, tripod, or tetrapod fracture, is a fracture commonly encountered by facial plastic surgeons. Failure to correctly reduce these fractures can lead to facial asymmetry, trismus, diplopia, enophthalmos, and parasthesias. Approaches to the zygomaticomalar complex have been well documented in the literature and include the transconjunctival lateral canthotomy, subciliary blepharoplasty, brow, gingivobuccal, and coronal incisions, or some combination thereof. Fracture fixation is accomplished by the internal placement of miniplates and microplates across properly reduced fracture lines to resist torsional rotation and masticatory distraction. The method of fracture reduction and fixation employed at the University Hospital of Bern, Switzerland, shares much with previously published and accepted methods of medial and lateral buttress reconstruction, but it introduces several original concepts in an attempt to maximize functional and aesthetic outcomes.

Management of Displaced Lateral Orbital Wall Fractures Associated with Visual and Ocular Motility Disturbances

Management of Displaced Lateral Orbital Wall Fractures Associated with Visual and Ocular Motility Disturbances

Frontal Basilar Trauma: Classification and Treatment

We report our experience with 14 consecutive cases of frontal basilar trauma occurring in children and adolescents aged 18 months to 18 years (mean 9.5 years). Brain parenchymal injury resulting in functional deficit occurred in 5 patients (36 percent), 2 patients suffered bilateral blindness, and 1 suffered unilateral loss of vision. A classification system and treatment algorithm based on the clinical fracture pattern seen by computed tomography are introduced. Type I, central, is confined to the upper nasoethmoidal complex, central frontal bone, and medial third of the superior orbital rims. Type II, unilateral, involves the entire supraorbital rim and the upper lateral orbital wall, extending into the squamosa of the temporal bone and ipsilateral frontal bone. Type III, bilateral, involves fractures of the upper nasal ethmoidal complex, bilateral supraorbital and upper lateral orbital wall fractures, and bilateral frontal bone fractures. This classification was utilized to plan elective orbital and cranial osteotomies, similar to those used for frontal orbital advancement at the time of acute fracture repair. Frontal orbital osteotomies were used to access the anterior cranial fossa, orbital apices, and nasofrontal ducts and to obtain an intact bony template for side-table reassembly of the fracture fragments. There was no significant operative morbidity, one late cerebrospinal fluid leak, and no infections. Reoperation was necessary in four patients (29 percent) for aesthetic indications.
