Targeted orbital intervention in the management of sino-orbital mucormycosis cases.

INTRODUCTION: Many countries from South-East Asia reported an epidemic of sino-orbital mucormycosis (SOM), otherwise a rare disease, during the coronavirus disease 2019 pandemic. SOM, a potentially fatal disease, is typically treated with orbital exenteration and systemic antifungals after metabolic stabilization. There is no clear evidence of survival benefit of exenteration in the literature, and thus, there have been attempts at globe conserving treatments like orbital infusion after limited debridement and intraorbital injections with Amphotericin B (IOAB). METHODS: We conducted a prospective comparative interventional study at a tertiary eye care hospital to evaluate treatment outcomes with the use of adjunctive IOAB in cases of SOM with mild to moderate orbital disease. RESULTS: Thirty-six patients of SOM with mild to moderate orbital disease were recruited in the study. In the intervention group, 23/26 (885%) eyes had stable orbital disease at the end of treatment (4-6 weeks). No deterioration in visual acuity was noted as a result of treatment. In 8/26 (30.77%) patients, inflammation was noted as a side effect of IOAB requiring temporary discontinuation of injections. The mean follow-up for cases was 14.2 months (range 12-15 months). 1/23 (4.35%) patients had relapse of orbital disease at 3 months. Twenty-one patients are alive on last follow-up. Of the patients who refused treatment (controls), 2/9 (22.22%) patients relapsed. One of these patients with relapse underwent exenteration, while the other was managed with IOAB. At a follow-up of 14 months (range 12-15 months), eight patients are alive. On evaluating the ocular parameters in salvaged eyes, improvement in extraocular movements was noted in 75-80% cases. The degree of proptosis and resistance to retropulsion did not change significantly. CONCLUSION: In the current study, an improvement in the globe salvage rates was noted in cases of SOM with mild to moderate orbital disease treated with adjunctive IOAB as compared to controls at a mean follow-up of 14 months, although it did not achieve statistical significance. The study supports the inclusion of IOAB in routine management of mild to moderate orbital disease.

A rare presentation of rhino-orbital-cutaneous mucormycosis in an immunocompetent patient: a case report.

Mucormycosis is a rare opportunistic infection caused by Mucorales fungi. Cutaneous mucormycosis typically present as chronic indolent infection, whereas rhino-orbital mucormycosis is rapidly progressive disease often invade the adjacent cerebral tissue associated with high mortality. This case represents the atypical clinical history of rhino-orbital-cutaneous mucormycosis. The patient was presented with a right orbital cellulitis associated with an extensive multiple suppurative deep cutaneous infection and worsening headache. The skin lesion was initiated from a localized abscess at the right periorbital area nine months before admission. Suspicion of fungal infection was raised after weeks of non-responsive antibiotics treatment. Aggressive treatment with exoneration of the right eye and surgical debridement was undertaken. Periodic acid Schiff staining from healthy periorbital tissue revealed ribbon-like hyphae with pauciseptate and 90° branching identified as Mucoraceaefamily. The resolution was seen after four weeks of antifungal treatment with Amphotericin B.

Traumatic Orbital Compression Syndromes: A Comprehensive Study Into Etiologies, Intervention Strategies, and Clinical Outcomes.

Facial fractures and their historical link to potential blindness have been well-documented, often attributed to optic canal injuries or retinal vascular occlusion. This dire consequence can result from both direct and indirect ocular trauma, including retrobulbar hemorrhage. Traumatic orbital compression can manifest in various forms, such as hematomas, fractured bone fragments, and emphysema, all posing a significant threat to vision, necessitating immediate intervention. In this study, 9 clinical cases of traumatic orbital compression are presented, each characterized by distinct etiologies. The study delves into traumatic orbital compressive syndromes, underscoring the critical imperative of early recognition and treatment to prevent vision loss. Orbital compression, whether from edema, hematoma, or emphysema, collectively culminates in elevated intraorbital pressure and the potential for optic nerve ischemia. Through the presentation of these 9 clinical cases, the article emphasizes the pressing need for timely intervention in addressing orbital compressive syndromes to avert vision loss. Various surgical techniques are elucidated, highlighting the pivotal role of expeditious medical intervention. This article offers invaluable insights into the diagnosis, management, and outcomes of traumatic orbital compressive syndromes.

Invasive Fungal Sinusitis and Its Orbital Morbidity in Pediatric Population: A Strategic Treatment Algorithm and Outcomes.

BACKGROUND: Invasive fungal sinusitis, particularly mucormycosis, presents a significant clinical challenge, especially in pediatric populations. This retrospective epidemiologic study aimed to investigate the clinical characteristics, risk factors and outcomes associated with this rare but severe condition, with a focus on orbital morbidity. METHODS: Clinical data of 12 pediatric patients diagnosed with invasive fungal sinusitis between 2021 and 2023 were retrospectively analyzed. Diagnosis involved microbiological and histopathologic examinations, alongside radiologic imaging. Treatment comprised surgical intervention and antifungal therapy, with a detailed evaluation of orbital involvement. Statistical analysis included descriptive statistics and logistic regression. RESULTS: Predominantly affecting males, the median age of the patients was 8 years. Common symptoms included orbital swelling and impaired vision. Imaging revealed characteristic features of invasive fungal sinusitis, including fat stranding and bone erosions. Orbital involvement was extensive, with poor visual outcomes observed in several cases. Surgical debridement and antifungal therapy, including transcutaneous retrobulbar Amphotericin B, were administered. Risk factors associated with poor orbital outcomes included duration of diabetes and glycated hemoglobin levels. Mortality rate stood at 22.2%. CONCLUSIONS: Early diagnosis, aggressive surgical intervention and combined antifungal therapy are essential for improving outcomes. Timely intervention showed stabilization of the orbital disease and better outcomes in pediatric patients. Further research with larger sample sizes is warranted to better understand and address this serious condition.

Characteristics and management of pediatric medial subperiosteal orbital abscesses.

INTRODUCTION: Subperiosteal orbital abscesses (SPOA) are the most common suppurative complications of acute bacterial sinusitis. Medial SPOAs arise from infection of the ipsilateral ethmoid sinus and favor initial conservative management reserving surgical drainage for patients who do not demonstrate clinical improvement. No standard algorithm defining medical versus surgical treatment of medial SPOAs exist in the pediatric population. OBJECTIVES: To identify a size cutoff for medial SPOAs to predict the likelihood for surgical drainage. METHODS: This is a retrospective review of patients with medial SPOAs at a tertiary care center from 2003 to 2017. Diagnosis of SPOA was based on radiographic findings. Variables included are patient demographics, antibiotic therapy, surgical intervention, and length of stay. RESULTS: 82 patients with a medial SPOA were included with an average age at presentation of 6.27 (range 0-15) years were included in this study. 62 patients were male (75.6 %), and 20 were female (24.4 %). The average abscess length was 16.1 mm, range 4.5-30.7 mm. The average abscess width was 4.17 mm, range 1.5-14.6 mm. The odds ratio for surgical treatment with every 1 mm increase in abscess width was 1.89 (95CI:1.33-2.69, p < 0.001). Abscesses over 3.6 mm width were 6.65 times more likely to undergo surgical drainage than those less than 3.6 mm (OR:6.65, 95CI:2.52-17.54, p < 0.001). The average(SD) length of stay was 5.4(3.0) days for patients who underwent surgery and 4.0(0.9) days for patients treated with conservative measures, p < 0.001. CONCLUSION: Medial SPOAs greater than 3.6 mm were more likely to undergo surgical drainage; however there was no difference in the likelihood of drainage between anteriorly and posteriorly based medial abscesses. These findings help further characterize the landscape of pediatric subperiosteal abscesses that are managed with surgical drainage.

[Interdisciplinary Management of Orbital Diseases]. / Interdisziplinäre Therapie der Erkrankungen der Orbita.

Diagnosis and therapy of orbital diseases is an interdisciplinary challenge, in which i.e. otorhinolaryngologists, ophthalmologists, radiologists, radiation therapists, maxillo-facial surgeons, endocrinologists, and pediatricians are involved. This review article describes frequent diseases which both, otolaryngologists and ophthalmologists are concerned with in interdisciplinary settings. In particular the inflammatory diseases of the orbit including orbital complications, autoimmunological diseases of the orbit including Grave´s orbitopathy, and primary and secondary tumors of the orbit are discussed. Beside describing the clinical characteristics and diagnostic steps the article focusses on the interdisciplinary therapy. The review is completed by the presentation of most important surgical approaches to the orbit, their indications and possible complications. The authors tried to highlight the relevant facts despite the shortness of the text.

Clinical characteristics and management of orbital apex syndrome: a 10-year multicentre experience.

BACKGROUND: Orbital apex syndrome (OAS) is a condition characterised by lesions within the orbital apex, leading to various ophthalmologic symptoms. This study aimed to analyse the clinical characteristics and treatment strategies of OAS with respect to aetiology. METHODS: This retrospective analysis utilised data from 5 medical institutions between 2013 and 2022. Patients who were diagnosed with OAS were initially enrolled, but patients who failed to follow up at least 1 month were excluded. The prevalence of initial ophthalmologic symptoms and visual improvement after treatment was compared according to aetiology. Factors related to visual improvement were analysed. RESULTS: Among 73 enrolled patients, the leading aetiology was tumours, followed by fungal infections and inflammation. Visual impairment and proptosis were prevalent in tumour-related OAS cases. Inflammation-related OAS exhibited a higher likelihood of painful eye movements and ophthalmoplegia. Ptosis was most frequently observed in fungal infection-related OAS. Notably, fungal infections emerged as the sole significant factor negatively impacting vision progression. In inflammation-related OAS, the time interval between symptom onset and the administration of steroids was longer in patients without visual improvement, even though there was no statistically significant difference. CONCLUSIONS: Tumours were the predominant cause of OAS. Visual impairment was a common manifestation in tumour-related OAS, while fungal infections were strongly associated with a poor visual prognosis. The timely administration of steroids might be helpful for improving vision in patients with inflammation-related OAS. However, further studies are needed to enhance understanding and management of OAS.

A 41-year-old with type 1 diabetes had generalized weakness, muffled voice, and slurred speech. Neck computed tomography showed soft-tissue gas in the nasopharynx and prevertebral fascia; examination of sinus mucosal samples identified numerous broad, nonseptate right-angled hyphae and fruiting bodies. What is the diagnosis and what would you do next?

Orbital complications of sinusitis in children - Retrospective analysis of an 8.5 year experience.

OBJECTIVE: Orbital complications account for approximately 74-85 % of all complications of acute sinusitis, affect the pediatric population more frequently, and can have devastating consequences. In the years following the COVID-19 pandemic (2022, 2023), a high number of children presented to our clinic with orbital complications. 1)Has there been an increase in orbital complications in the post-covid era? 2)To what extent has the use of MRI reduced radiation in pediatric patients? DESIGN: In our retrospective data analysis, all pediatric patients (age 0-16 years) treated at a university ENT clinic during the period 01/2014-06/2023 who presented with an orbital complication of rhinosinusitis were included. The analysis was descriptive. RESULTS: Forty-four children with orbital complications of rhinosinusitis were treated during the study period, 14 females and 30 males. Most patients (n = 23, 52 %) presented during the years of the waning Covid-19 pandemic (01/2022 to 06/2023). MRI was the initial imaging modality (n = 22,50 %); CT was performed in 17 of 44 cases (39 %) when surgery was indicated. The most common germ detected was of the Streptococcus species, and the predominant antibiotic administered was amipicillin/sulbactam. CONCLUSION: The standard operating procedure (SOP) established at our hospital in 2014 was followed in 42/44 cases. Except for 2 cases, CT was performed exclusively when surgery was indicated. Imaging-related radiation could be avoided in 27 patients (61 %). There was a 30 % increase in orbital complications related to sinus infections postpandemically.

Role of Acute Rhinosinusitis in Periorbital Infections in Children.

OBJECTIVE: Periorbital cellulitis in children are commonly caused by acute rhinosinusitis (ARS). This study investigated the association of ARS and the severity of periorbital cellulitis in children. STUDY DESIGN: Retrospective case-control study of children with periorbital cellulitis with ARS versus periorbital cellulitis without ARS. SETTING: Patients were seen at West Virginia University Children's Hospitals between August 2011 to August 2022. METHODS: Patients were divided into cases and controls based on presence or absence of ARS. ARS was defined based on clinical symptoms with objective presence of disease on CT scan. Patients' characteristics, treatment, hospital length of stay, and readmission were collected. RESULTS: The sample consisted of 118 pediatric patients with orbital cellulitis. Patients with ARS were younger than patients without ARS (6.3 vs 8.5, p = 0.025), however there were no sex differences between two groups (p = 0.540). The ARS group had higher incidence of postseptal cellulitis (51.5% vs 9.6%, p < 0.001). As compared to patients without ARS, patients with ARS were more likely to be admitted (p < 0.001), have a longer length of stay (median of 3.5 days vs 0.5 days, p < 0.001), require IV antibiotics (95.3% vs 54.9%, p < 0.001), and require surgical intervention (23.1% vs 5.8%, p < 0.001). Readmission rate was similar between the two groups. CONCLUSION: Children presenting with acute periorbital cellulitis who have ARS tend to have more severe infection requiring higher level of care. ARS should be assessed and incorporated into the plan of care of pediatric patients with periorbital infections.

Pediatric orbital subperiosteal abscess outbreak in Iran: characteristics and causes.

PURPOSE: To evaluate demographics, characteristics, and management of pediatric patients with subperiosteal abscesses (SPA) secondary to orbital cellulitis and discuss the etiology of a dramatic rise in SPA. METHODS: Data were gathered by retrospective chart review of patients admitted to a tertiary referral eye hospital (Farabi Eye Hospital) diagnosed with orbital cellulitis with subperiosteal abscess from October 2022 to March 2023 (six months). Data on demographic information, clinical examination, radiographic evidence of sinusitis, orbital cellulitis, SPA, surgical and non-surgical management taken, isolated bacteria, and duration of hospital stay were gathered. RESULTS: 24 patients were admitted during these six months, with a diagnosis of orbital SPA secondary to paranasal sinusitis, confirmed by an orbital Computed Tomography (CT) scan. The age range was 11 months to 16 years. 75% of patients were male. All patients had a history of flu-like illness before developing orbital cellulitis. All patients had concurrent sinusitis, and 18 underwent initial surgical abscess drainage. The ethmoid sinus was the most involved, and most patients had a medially located SPA. Abscess volume ranged from 0.78 to 7.81 cm3 (mean: 3.52 cm3). One patient had concurrent central retinal artery occlusion due to orbital cellulitis. CONCLUSIONS: In this study, we report a dramatic increase in the incidence of SPA referred to our hospital. Larger abscess volumes and an increased number of cases that needed initial surgical drainage are also of note. An influenza outbreak in the autumn and winter, undiagnosed Corona Virus Disease 2019 (COVID-19) infection, increased antimicrobial resistance due to excessive off-label use of antibiotics during the COVID-19 pandemic, and more virulent bacterial infections are the most probable hypotheses to justify this observation.

Study of rhino-orbital-cerebral mucormycosis and its correlates during COVID-19 pandemic in a tertiary eye care institute of central India.

PURPOSE: To evaluate factors associated with the occurrence of ROCM in COVID-19 patients and to compare its related parameters and outcomes between active and recovered COVID-19 groups. METHODS: A total of 35 patients of ROCM associated with COVID-19 (active and post-COVID-19) were included. This is an ambispective study with retrospective medical records review for COVID-19 analysis and prospective assessments of ROCM-associated COVID-19 during the second wave of the COVID-19 pandemic. The demographic data, clinical parameters, and outcome were recorded on MS excel sheet, and various parameters were compared between active and recovered COVID-19 groups. RESULTS: ROCM in recovered COVID-19 group was higher (57.1%) as compared to active COVID-19 (42.9%) (P = 1.00). High occurrence of ROCM was seen in those who had a history of hospitalization due to severity of COVID-19 (n 33, 94.28%), oxygen support (77.14), and received systemic steroids (82.9%). The most common comorbidity was diabetes mellitus (82.9%), and new-onset hyperglycemia was noticed in 17.1% of patients. Exenteration (28.6%) was performed in severe cases who had stage IV ROCM, bilateral, and CNS involvement (RR = 7.2, 95% CI: 2.91 to 18.00). The risk of globe exenteration was 1.35 (0.7-2.29) times higher in recovered COVID-19 group, and mortality was 1.76 (0.72-3.36) times higher in active COVID-19 group. CONCLUSION: Monitored use of systemic steroids and the prompt management of hyperglycemia in COVID-19 patients are important factors for favorable outcomes with reference to globe salvage and life-saving in ROCM associated with COVID-19. Even recovered COVID-19 patients should be observed for persistent hyperglycemia and occurrence of ROCM.

Case series of central retinal artery occlusion in COVID-19-associated rhino-orbital-cerebral mucormycosis.

Rhino orbital Mucormycosis caused by filamentous fungus of mucoraceae family was considered a rare disease affecting immunocompromised and diabetics with ketoacidosis until the recent COVID 19 pandemic. We are presenting a series of six cases of Rhino orbital cerebral Mucormycosis with central retinal artery occlusion. All six cases had common history of COVID 19 infection in recent past with sinusitis, proptosis and total ophthalmoplegia with central retinal artery occlusion on presentation. MR imaging showed invasive pan sinusitis with orbital and cerebral involvement. Urgent debridement was done and histopathological examination showed broad, filamentous aseptate fungi suggestive of Mucormycosis. All patients inspite of intravenous Amphotericin B with local debridement did not show any improvement and expired within a week of presentation. Hence our study shows poor prognosis of post covid 19 associated Mucormycosis with central retinal artery occlusion.

[COVID-19 associated sino-orbital mucormycosis]. / COVID-19-assotsiirovannyi sinoorbital'nyi mukormikoz.

OBJECTIVE: To analyze the dynamics of symptoms in patients with COVID-19 associated sino-orbital mucormycosis. MATERIAL AND METHODS: We describe a series of 13 patients with COVID-19 associated sino-orbital mucormycosis aged 43 to 80 years diagnosed from August to October 2021. All of the patients had a severe disease and required noninvasive ventilation or intubation and administration of dexamethasone. 12 out of 13 patients (92.3%) suffered from diabetes mellitus. Symptoms of fungal infections of the nose and paranasal sinuses appeared in the interval from 7 to 25 days of hospital stay, most often in the second week (from 8 to 12 days). According to clinical and CT features the patients were divided into three groups, combining similar phenotypes of the disease. Group 1 - 1 patient with sinonasal mucormycosis, destruction of the alveolar ridge and the hard palate. Group 2 - 12 patients with sino-orbital mucormycosis. We noted, that in cases of bilateral sinus lesions orbital complications were unilateral in all patients, on the side of more severe lesion. Group 2 was divided into 2 subgroups: subgroup 2a included 2 patients with the superior orbital fissure syndrome: ptosis, proptosis, ophthalmoplegia, periorbital pain, pain or hypoesthesia of half face; subgroup 2b included 10 patients with the orbital apex syndrome, who, in addition to the above symptoms, had loss of vision and conjunctival chemosis. Group 3 - rhino-sino-cerebral mucormycosis. 2 patients from subgroup 2b were transferred to this group due to the intracranial spread of the process and focal neurological symptoms. CONCLUSION: Clinical forms of mucormycosis reflect successive stages of invasive spread of fungi.

[Diagnosis and management of orbital and cranial complications of pediatric acute rhinosinusitis].

Objective: To review the clinical characteristics, to illustrate diagnosis and management experience of orbital and cranial complications of pediatric acute rhinosinusitis. Methods: The clinical data of 24 children with orbital and cranial complications of acute rhinosinusitis who received endoscopic sinus surgery combined with drug treatment in Beijing Children's Hospital from January 2017 to December 2021 were retrospectively reviewed. There were 19 boys and 5 girls. The age varied from 13 to 159 months, with a median 47.5 months. The following diagnoses were obtained: 12 isolated subperiosteal orbital abscess, 2 associated with preseptal abscess, 2 associated with intraorbital abscess, 7 associated with optic neuritis, and 1 associated with septic cavernous sinus thrombosis. Clinical characteristics, organism isolated and outcomes were analyzed through descriptive methods. Results: All 24 patients presented with fever; 9 presented with nasal congestion and purulent discharge. The clinical manifestations of orbital infection included orbital edema, pain, proptosis and displacement of globe in all patients, while visual impairment was recognized in 7 children. Purulent drainage was cultured in 17 patients, among which 12 were positive. All patients underwent nasal endoscopic surgical interventions uneventfully, excluding one patient who required a second surgical procedure. Follow-up period ranged from 5 to 64 months. All patients resolved fully, with the exception of 2 children who got permanent blindness with visual loss preoperative. There was no recurrence or death. Conclusions: Orbital and cranial complications of pediatric acute rhinosinusitis could be severe with an occult onset. For patients with vison impairment, any signs of intracranial complications and a lack of response to conservative management, an urgent endoscopic intervention is needed.

Central Retinal Artery Occlusion in Rhino-Orbital-Cerebral Mucormycosis: An Inflammatory-Prothrombotic State.

PURPOSE: The aim was to evaluate patient profiles of rhino-orbital-cerebral mucormycosis (ROCM) cases with central retinal artery occlusion (CRAO) postcoronavirus disease 2019. DESIGN: A nonrandomized retrospective case-control study. METHODS: The ROCM cases presenting with CRAO were compared with a control ROCM group without CRAO at a tertiary care center. Demography, systemic status, clinical features, histopathology, imaging, and blood profile were assessed for any specific risk factors. RESULTS: A total of 12 patients were seen in the CRAO group and 16 in the non-CRAO group. The male-to-female ratio was 3:1 with a mean age of 49.5 years. In the CRAO group, 75% had diabetes mellitus with mean hemoglobin A1c of 9.03%, and 66.7% had received steroid treatment. All cases were histopathologically confirmed positive for mucor. There was a significant difference in mean D-dimer and serum ferritin between the 2 groups, with higher level in the CRAO group. All patients with CRAO had light perception-negative vision, with total ophthalmoplegia and proptosis seen in 66.7% of cases. Four patients had orbital apex involvement, 5 had cavernous sinus involvement, and 8 had intracranial involvement in the CRAO group. CONCLUSIONS: Inflammatory markers D-dimer and serum ferritin were significantly associated with CRAO, suggestive of hyperinflammatory and hypercoagulable state. A high index of suspicion should be maintained in cases with elevated markers and prophylactic anticoagulants can be started to prevent CRAO in a subset of patients.

[Paying attention to the innovation on therapeutic methods of orbital vascular malformation].

Orbital vascular malformation, one of the common orbital diseases, is confronted with problems like complex clinical manifestations, difficulties in treatment, and poor efficacy. In recent years, the therapeutic methods have been continuously explored and expanded, including sclerotherapy, laser coagulation, intra-arterial embolization, surgical resection, and targeted therapy. And the technology has been constantly innovated and improved to overcome difficulties in treatment and enable more favorable outcomes of orbital vascular malformation. By summarizing the existing innovations, this article proposes to study the pathogenesis, widely explore novel therapeutic targets, and integrate advanced auxiliary technologies, so as to develop more accurate and minimally invasive therapies for orbital vascular malformation.

[Treatment of orbital vascular malformations with intralesional bleomycin injection and N-butyl-2-cyanoacrylate glue embolization].

Objective: To evaluate the clinical efficacy of bleomycin lavage combined with N-butyl-2-cyanoacrylate glue embolization and resection in the treatment of orbital vascular malformations. Methods: It was a retrospective case series study. Patients with orbital vascular malformations diagnosed at the Ophthalmology Division of Chinese PLA General Hospital from January 2018 to October 2021 were included and divided into exophthalmos group and non-exophthalmos group based on whether the patients had postural exophthalmos. Intralesional bleomycin injection and N-butyl-2-cyanoacrylate glue embolization were performed. The preoperative and postoperative visual acuity, the dosages of bleomycin and isobutyl cyanoacrylate glue, pathological results, imaging findings and remission rate were recorded and analyzed. The Chi-square test, Wilcoxon signed rank analysis and Mann-Whitney U test were used for statistical analysis. Results: A total of 58 patients (58 eyes)were included, and there were 22 males (37.9%)　and 36 females (62.1%). Nineteen (32.8%) patients had postural exophthalmos, and 39 (67.2%) patients did not suffer postural exophthalmos. The patient's age of the two groups was 39.0 (28.0, 54.5) years vs. 14.0 (5.7, 26.5) years, with a statistically significant difference (Z=-3.96, P<0.001). There was no significant difference in gender, eye laterality, follow-up time and the disease course between the two groups (all P>0.05). During the operation, the dosage of bleomycin was 15 000 (13 500, 15 000) U in the exophthalmos group, and 15 000 (9 000, 16 500) U in the non-exophthalmos group (Z=-0.70, P=0.944). The dosages of N-butyl-2-cyanoacrylate glue were 2.8 (1.0, 3.0) ml and 1.7 (1.0, 2.2) ml, respectively, in the two groups, with no significant difference (Z=-1.11, P=0.268). There was no visual impairment in both groups, while the visual acuity in 5 patients without postural exophthalmos was improved postoperatively. The imaging examination results showed no difference in the malformed vascular area before and after the treatment in the exophthalmos group [384.0 (329.0, 458.0) mm2 vs. 330.5 (271.6, 356.7) mm2; Z=-1.26, P=0.208], but a significantly decreased area after the treatment in the non-exophthalmos group [960.8 (822.1, 1058.3) mm2 vs. 311.6 (164.6, 361.6) mm2; Z=-2.67, P=0.008]. All patients had no obvious local or systemic adverse reactions during the follow-up. The pathology reports showed vascular malformations in all 15 specimens obtained from the exophthalmos group, as well as vascular malformations in 41.0% (16/39) of specimens and venous lymphatic malformations in 59.0% (23/39) of specimens from the non-exophthalmos group. Thirty-nine patients had complete remission (67.2%), 19 patients had partial remission (32.8%), and the effective treatment rate was 100%. Conclusion: Bleomycin lavage combined with N-butyl-2-cyanoacrylate glue embolization can achieve good therapeutic effects on orbital vascular malformations.
