Congenital orbital teratoma: a rare case with intracranial extension.

INTRODUCTION: Teratoma is the most common congenital tumor, but the orbital location is rare. It is composed of tissues from ectoderm, mesoderm, and endoderm. CLINICAL PRESENTATION: Congenital orbital teratoma commonly presents as unilateral proptosis, with rapid growth, leading to exposure keratopathy. DIAGNOSIS: Prenatal ultrasound may detect the orbital mass, computed tomography (CT) scans, and magnetic resonance (MR) imaging are better in demonstrating multilocular cystic and solid mass, without bone erosion. Laboratory tests should include alfa-fetoprotein (AFP) and B-human chorionic gonadotropin (B-HCG), and histopathologically, it contains all three germ cell layers components. The management is surgical removal of the lesion, the mature teratoma has a benign behavior, and the immature has a poor prognostic. We describe a rare case of congenital orbital teratoma with intracranial extension of the lesion, in which was treated with orbital exenteration. After surgery, AFP levels decreased, the middle face displacement has improved and development milestones were appropriate.

Endoscopic-assisted transorbital extended orbital exenteration: A multi-institutional preclinical study.

BACKGROUND: Sinonasal malignancies with orbital invasion have dismal prognosis even when treated with orbital exenteration (OE). Sugawara et al. developed a surgical strategy called "extended-OE (EOE)," showing encouraging outcomes. We hypothesized that a similar resection is achievable under endoscopic guidance through the exenterated orbit (endoscopic-EOE). METHODS: The study was conducted in three institutions: University of Vienna; Mayo Clinic; University of Insubria; 48 orbital dissections were performed. A questionnaire was developed to evaluate feasibility and safety of each step, scoring from 1 to 10, ("impossible" to "easy," and "high risk" to "low risk," respectively), most likely complication(s) were hypothesized. RESULTS: The step-by-step technique is thoroughly described. The questionnaire was answered by 25 anterior skull base surgeons from six countries. Mean, median, range, and interquartile range of both feasibility and safety scores are reported. CONCLUSIONS: Endoscopic-EOE is a challenging but feasible procedure. Clinical validation is required to assess real-life outcomes.

Preservation of orbit in tumor invasion through the periorbita in sinonasal malignancy.

OBJECTIVE: One of the possible risks of sinonasal malignancy is its possible spread in the orbit. However, there is no clear consensus among the different departments as to whether it is necessary to exenterate the orbit in limited tumorous infiltration of periorbital fat. The purpose of the study was to demonstrate that periorbital infiltration and periorbital fat invasion without involvement of deeper orbital tissues are not the indication of orbital exenteration. MATERIALS AND METHODS: Retrospective analysis was performed over a 17-year period of patients undergoing surgical treatment for sinonasal malignancy with histologically verified periorbital infiltration or deeper invasion into the orbit. A total of 32 patients were included in the study. For each group, the following data were analysed: sex, age, preoperative imaging studies, histological findings, site of origin, stage, surgical reconstruction, oncological treatment, survival, cause of death, number of recurrences in the orbit and functional status of preserved eyes. RESULTS: Based on our criteria for orbital exenteration, orbital preservation was feasible in 18 patients. Orbital exenteration was performed in 14 patients with deeper tumor infiltration. There was a statistically insignificant difference in survival between the two groups. The 5-year overall survival (OS) was 44% for the orbital preservation group (only 2 patients died from local tumor recurrence) and 34% for the orbital exenteration group. The groups did not differ in other observed factors other than the extent of orbital infiltration. In 11 (61.1%) patients, vision was without significant change after radiation therapy. In 2 (11.1%) patients, visual function was impaired due to diplopia. 5 (27.8%) patients had severely impaired vision due to optic nerve atrophy after radiation therapy. CONCLUSIONS: Our results show a relatively high survival rate in the group of patients with orbital preservation with a high chance of vision preservation, which justifies our approach to orbital preservation even in some tumors with periorbital infiltration.

The role of induction chemotherapy for orbital invasion in sinonasal malignancies: A systematic review.

BACKGROUND: Sinonasal malignancies (SNMs) frequently present with orbital invasion. Orbital exenteration (OE) can lead to significant morbidity. Induction chemotherapy (IC) is a promising treatment alternative that may allow for orbit preserving (OP) treatments without compromising patient survival. This systematic review was conducted to synthesize the published data on SNM patients with orbital invasion who underwent IC, including tumor response, orbital outcomes, and survival. METHODS: The study protocol was designed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. Databases Embase, Cochrane, Medline, and Scopus, from inception to July 17, 2023, were searched. RESULTS: Nineteen studies were included, encompassing 305 SNM patients with orbital invasion treated with IC. Fourteen studies reported an overall IC response rate (positive response defined as complete or partial tumor volume reduction) of 77.2%. Among included studies, OE rates after IC ranged from 0 to 40%. Three studies reported a high rate of posttreatment functional orbital preservation (89.8-96.0%). Five studies specifically reported that 62.5% (60 out of 96) of patients were downgraded from planned OE to OP treatment following IC. Three studies reported a significant overall survival (OS) improvement in IC responders versus IC nonresponders. Following IC, 5-year OS ranged from 44.2 to 55.5%. Patients with olfactory neuroblastoma demonstrated the highest IC response rate and lowest OE rate (100 and 0%, respectively) versus those with sinonasal undifferentiated carcinomas (68.4 and 0%) or squamous cell carcinomas (76.7 and 16%). CONCLUSIONS: For select patients, IC may allow for OP in locally advanced SNMs with orbital involvement.

Nodulo-ulcerative squamous cell carcinoma of the conjunctiva mimicking necrotizing sclerokeratitis in a young patient.

Purpose: A delay in diagnosing and treating ocular surface squamous neoplasia (OSSN) with an atypical manifestation can lead to a progression to more advanced stages, resulting in a decrease in cure rates and treatment effectiveness. Observations: This case report describes a 21-year-old white male who presented to our Cornea Division with peripheral nasal corneal and scleral thinning with prolapse of uveal tissue in the right eye for over four months and who had received a sclerocorneal patch graft. The patient underwent systemic immunosuppressive therapy for presumed Mooren's ulcer after laboratory evaluation eliminated a collagen vascular disorder. Approximately three months after the procedure the patient returned with an inferior and superior sclerocorneal perforation. Six months after the first visit to our department, he returned to our ophthalmological emergency department with self-evisceration of the intraocular contents. He underwent an emergency evisceration procedure, and histopathological analysis of the intraocular contents revealed a poorly differentiated nodulo-ulcerative squamous cell carcinoma of the conjunctiva with intraocular invasion. A tomographic evaluation suggested orbital invasion. Subsequently, he underwent exenteration. Conclusions and Importance: OSSN should be considered in the differential diagnosis of corneal or scleral thinning, perforation, and inflammation of an unknown cause even in young patients, especially after systemic disorders have been excluded.

"Ice cream cone" design of forearm free flap for orbital exenteration reconstruction.

BACKGROUNDS: Reconstruction post-orbital exenteration serves the dual purpose of expediting healing, laying the groundwork for cosmetic restoration, and minimising complications such as orbitosinusal fistulae. The aim of this study was to introduce a modified "Ice cream cone" (ICC) design of the Radial Forearm Free Flap (RFFF) technique used for reconstruction of orbital exenteration cavity, along with the oncological, functional, and aesthetic outcomes. METHODS: The authors conducted a retrospective study between January 2005 and December 2020. Inclusion criteria encompassed patients treated for orbitosinusal malignancies undergoing exenteration with subsequent ICC design of RFFF reconstruction. RESULTS: Twenty-two patients underwent exenteration with the ICC design of RFFF. At the follow-up conclusion, 65% of patients regularly used orbital prosthesis. The average waiting time until the prosthesis was 10 months. Quality of life questionnaires yielded average RFFF POSAS scores of 23.5 (SD 13,6), cervical POSAS scores of 8 (SD 13,2), and orbital cavity rehabilitation scores of 5.9 (SD: 3,32). CONCLUSIONS: ICC design of RFFF is a reliable technique. It can be proposed in cases of extended exenteration with a high risk of cerebrospinal fluid (CSF) but more generally in cases of total exenteration. This technique facilitates optimal postoperative wound healing and accommodates early radiotherapy. Importantly, the bowl-shaped aspect of the orbital socket supports effective prosthetic rehabilitation for patients opting for orbital prosthesis post-surgery.

Advances in Microvascular Reconstruction of the Orbit and Beyond: Considerations and a Checklist for Decision-Making.

This paper aims to discuss the microvascular reconstruction of the orbit and adjacent regions and to propose a checklist to aid the reconstructive surgeon in this challenging undertaking. The discussion is based on a literature review that includes 32 retrospective case series, 5 case reports published in the last 34 years in PubMed, and 3 textbook chapters. Additionally, it relies on the senior author's expertise, described in a case series, and two case reports published elsewhere. Classifications and treatment algorithms on microvascular orbit reconstruction generally disregard patient-related factors. A more holistic approach can be advantageous: patient-related factors, such as age, comorbidities, prognosis, previous interventions, radiotherapy, and the wish for maximal dental rehabilitation and a prosthetic eye, have the same importance as defect-related considerations and can inform the choice of a reconstructive option. In this manuscript, we examine defect- and patient-related factors and new technologies, provide a checklist, and examine future directions. The checklist is intended as a tool to aid in the decision-making process when reconstructing the orbital region with microvascular flaps.

Ophthalmic presentation and outcomes of rhino-orbito-cerebral mucormycosis during the COVID-19 pandemic: An 18-month follow-up report.

PURPOSE: To investigate the long-term outcomes of COVID-19-associated rhino-orbito-cerebral mucormycosis (ROCM) patients. METHODS: Retrospective, observational study including all COVID-19 patients who developed ROCM and were referred to our oculoplastic clinic. RESULTS: Twenty-one patients with COVID-19-associated ROCM were included in this study. Twelve (57.1%) individuals were female with a mean age of 50.7±7.6 years (range 33-59), and nine (38.1%) were male with a mean age of 58.7±14.4 years (range 37-82). Corticosteroids were used in 85.7% of patients, and three patients received no systemic corticosteroids; 76.2% were diabetic and two of these developed new-onset diabetes mellitus (DM) after receiving corticosteroids during their treatment course. The average interval between COVID-19 and the development of ROCM in our subjects was 18.6 days (range 8-46 days). In our series of patients, decreasing vision, proptosis, and periorbital edema constituted the most prevalent presentation, seen in 52.4% of subjects. Endoscopic paranasal sinus debridement was performed a mean of 3.4 times in 95.2%, abscess drainage in one, and orbital exenteration in three (14.2%) patients. Orbital apex and bilateral paranasal sinus involvement were significantly associated with higher mortality, and the overall 18-month survival rate was 52.3%. CONCLUSION: Based upon common factors among the COVID-19-associated ROCM patients, we presume that DM and drug-induced immunosuppression are two main factors, which may lead to a higher rate of ROCM infection in areas where fungal spores are more likely to be present, such as hospitals.

Leiomioma orbitario gigante en un paciente pediátrico: reto diagnóstico y terapéutico / Giant orbital leiomyoma in a pediatric patient: Diagnostic and therapeutic challenge

Este manuscrito presenta un caso de un leiomioma orbitario de larga evolución en un joven de 14años. El tumor era inusualmente grande y causaba una proptosis severa y una afectación importante de la musculatura ocular. El paciente presentaba amaurosis, una oftalmoplejía completa, dolor ocular espontáneo e incapacidad para cerrar los párpados. Debido al tamaño del tumor y a su progresión, se realizó una exenteración orbitaria derecha para eliminar todo el contenido orbitario, incluyendo el tumor y el globo ocular. El procedimiento quirúrgico tenía como objetivo prevenir la recurrencia del tumor y mejorar la calidad de vida del paciente. El análisis histopatológico confirmó el diagnóstico de leiomioma orbitario. Este caso presenta un interés particular por el grado de evolución que ha alcanzado. La extirpación completa del tumor y un seguimiento a largo plazo son necesarios para prevenir la recurrencia y garantizar resultados óptimos para el paciente. Además, este caso refleja las grandes diferencias en el acceso a la sanidad en las diferentes regiones del mundo. (AU)

This manuscript describes an exceptional case of a long-standing orbital leiomyoma in a 14-year-old male. The tumor was unusually large, causing severe proptosis and significant involvement of the ocular muscles. The patient presented with amaurosis, complete ophthalmoplegia, spontaneous eye pain, and the inability to close the eyelids, leading to psychological distress. Due to the tumor's size and progression, a right orbital exenteration was performed to remove all orbital contents, including the tumor and the eyeball. The surgical procedure aimed to prevent tumor recurrence and improve the patient's quality of life. The histopathological analysis confirmed the diagnosis of orbital leiomyoma. This case presents a particular interest due to the degree of evolution it has reached. Complete tumor excision and long-term follow-up are necessary to prevent recurrence and ensure optimal patient outcomes. This report underscores global healthcare disparities and the complexity of managing rare orbital neoplasms in diverse country settings. (AU)

Survival of a Rhino-Orbital-Cerebral Mucormycosis Patient after Localized Combination Liposomal Amphotericin B Medications: A Case Report.

Introduction: The aim of this study was to report a case of ROCM related to nasogastric intubation who was survived by liposomal amphotericin B (LAmB) combination therapy in situ without orbital exenteration. Case Presentation: A 44-year-old woman presented with a 1-week history of rapidly enlarging swelling on the right nose, cheek, and lower eyelid after underwent gastrointestinal decompression. The lesions were derived from the nasal area where the nasogastric tube had been placed. Based on the biopsy results and clinical manifestations, ROCM was diagnosed. Immediate combination therapy with intravenous LAmB and micafungin and multisection debridement of the right facial region were applied. Postoperative treatment included cleaning, irrigating, and local dressing of the wound area using LAmB. LAmB was also used daily as binocular eye drops against deep infection on the eyeballs. The patient recovered well 4 months later and remained free of disease after 40 months of follow-up. Conclusion: This case adds to our knowledge on the potential risk of nasogastric intubation for mucormycosis infection. Nasogastric tube may be the source of infection associated with ROCM. This report evaluates the beneficial effect of LAmB combination therapy in situ for cleaning, irrigating, local wound dressing, and eye drops on lesion areas. The combination of LAmB as cleaning, irrigating, local dressing solution, and eye drops to control intraocular and intraorbital ROCM infection has not been previously reported to our knowledge. These methods provide multiple choices to substitute for orbital exenteration on the survival of ROCM patients.

Risk Factors for Orbital Invasion in Malignant Eyelid Tumors, Is Orbital Exenteration Still Necessary?

Basal cell carcinoma is the most common malignant skin tumor of the eyelids in Caucasians, followed by squamous cell carcinoma and sebaceous gland carcinoma. The primary treatment for these tumors is radical excision. In cases where malignant eyelid tumors are advanced and have invaded the orbit, orbital exenteration is necessary. In this retrospective study, we aimed to determine the correlation between the risk of orbital infiltration and various factors like tumor location, size, histological type, and patient age. This study revealed that tumors in multiple regions increased the risk of orbital infiltration by 3.75 times. Tumors with a diameter of 21-30 mm raised the likelihood of requiring exenteration by 15.5 times compared to smaller tumors (up to 10 mm). Age was also associated with the likelihood of orbital invasion in periocular tumors. Interestingly, no correlation was found between the histological type of the tumor and the risk of orbital infiltration. Notably, the conjunctiva of the eyeball was the most commonly infiltrated orbital structure, followed by the orbital fat. Timely treatment and well-planned procedures are crucial for patients with malignant periocular skin tumors to avoid multiple reoperations and the potential need for orbital exenteration.

A case of primary orbital liposarcoma with dedifferentiated transformation from a well-differentiated form.

Purpose: Primary orbital liposarcomas are rare. To the best of our knowledge, only four cases of primary dedifferentiated liposarcomas of the orbit have been reported. Furthermore, there have been no reports of primary orbital liposarcomas transitioning from a highly differentiated to a dedifferentiated form. Here, we report a case of primary orbital liposarcoma that was well-differentiated at the time of initial resection at our hospital but had dedifferentiated on recurrence 10 years after the initial resection. Observations: The patient was diagnosed with an inflammatory mass after an initial tumor resection by a previous physician at age 52. Thereafter, there were four recurrences (first to fourth recurrences), and the patient underwent five surgeries and radiotherapy. For the fifth recurrence, he first visited our hospital at age 64 and was diagnosed with a well-differentiated liposarcoma after undergoing tumor resection. When the tumor recurred 9 years later (the sixth recurrence), it was well-differentiated. When the tumor recurred (the seventh recurrence) six months after surgery at the age of 73 years, the patient underwent orbital exenteration because of rapid tumor growth, and pathological examination showed that the tissue had changed to a dedifferentiated liposarcoma. Conclusions and Importance: Primary well-differentiated orbital liposarcoma may transform to a dedifferentiated form over time. The risk of dedifferentiation at recurrence should be considered in developing a treatment plan, even if the initial pathology is a well-differentiated liposarcoma.

Extended orbital exenteration, epithetic restoration, and patient supply: A cross-sectional study of a historic cohort.

BACKGROUND: The aim of this study was to investigate the clinical course and to redefine an optimized algorithm for OE cases until epithetic restoration. METHODS: Indication, defect type according to Kesting, reconstructive technique, incidence of postoperative complications and peri-implantitis, patients' quality of life, timing of periorbital implant insertion, incidence of and interval to implant loss, and time until epithetic restoration were analyzed in 43 patients. RESULTS: A significant correlation was detected between wound dehiscence and defect type. Out of 24 patients, 7 were implanted secondarily with a median time interval of 399 days (270-2015) after OE. Eleven out of 83 placed implants were lost in 8 patients with a median time interval of 586 days (264-4485) after insertion. The majority of epithesis carriers had no or few restrictions in their quality of life. CONCLUSIONS: We recommend our modified treatment algorithm to further improve and shorten the clinical course.

Survival Analysis and Prognostic Factors for Peri-ocular Malignancies in Malaysia

@#Introduction: This study aims to determine the prognostic factors and survival outcomes of patients that underwent this surgery. Method: A retrospective review of 43 patients who underwent exenteration for periocular malignancies over a 14-year period was carried out. Patient demographics, tumour histology, treatment details, surgical margins’ status and post-operative survival were recorded. The survival outcome examined was the overall survival (OS) rate. Cox regression and Kaplan-Meier analysis were used to evaluate post-exenteration survival. Results: In total, 20 females and 23 males with a median age of 62 ± 17.3 years were identified. The most common indication for exenteration was basal cell carcinoma (20.9%), followed by squamous cell carcinoma (18.6%), adenocystic carcinoma (14%), malignant melanoma (14%) and sebaceous gland carcinoma (11.6%). The independent predictors for worse OS on multivariate analysis were Chinese ethnicity (adjusted hazard ratio [aHR] 4.95, p =0.017), sebaceous gland carcinoma (aHR 57.61 p=0.006), adenocystic carcinoma (aHR 45.87, p=0.008), clear surgical margins (aHR 5.41, p=0.025), receiving only chemotherapy (aHR 169.13, p=0.004), and receiving both adjuvant chemotherapy and radiotherapy (aHR 41.51, p=0.010). Conclusion: We recommend targeted public health initiatives for Chinese patients due to their increased mortality risk from peri-ocular malignancies. In addition, we advise comprehensive adjuvant therapy for all patients regardless of whether a clear surgical margin is achieved. Basal cell carcinoma and adenocystic carcinoma may also benefit from genetic research. We advocate more training for ophthalmologists to identify periocular malignancies earlier for better treatment options and increased chances of survival.

Orbital Exenteration: Tumour Diversity and Survival-Report from a Cancer Centre of Northeast India.

Orbital exenteration is a mutilating surgery which involves the removal of the entire contents of the bony orbit, including the globe, extraocular muscles and periorbital fat, and many times includes the eyelids. Since it leads to severe disfigurement, it is an infrequent procedure largely indicated in malignant conditions. The current study aims to report the clinicodemographic profile and treatment outcome of orbital exenteration patients done in a cancer care center in Northeast India. This is a hospital-based retrospective study between January 2017 and December 2021, including patients undergoing orbital exenteration. All patient and treatment-related data were retrieved from the record of hospital files. A total of 18 patients were included in the study. The mean age of the patients was 51 ± 18 years and male: female ratio was 1:1. Most patients had primary in orbit (55.6%). The most common histology was squamous cell carcinoma, (8/18, 44.4%), followed by basal cell carcinoma (two patients, 11.1%). After a median follow-up was 25 months (range 3-92), the median DFS of the study population was 31.4 months. The five-year overall survival of the patients was 54%. Orbital exenteration is an infrequent surgery due to the associated disfigurement and hence reserved for conditions where eye preservation is impossible. We tried to report the experience of orbital exenteration from a single cancer center for five years.

Orbital Exenteration for Craniofacial Lesions: A Systematic Review and Meta-Analysis of Patient Characteristics and Survival Outcomes.

BACKGROUND: The outcomes of orbital exenteration (OE) in patients with craniofacial lesions (CFLs) remain unclear. The present review summarizes the available literature on the clinical outcomes of OE, including surgical outcomes and overall survival (OS). METHODS: Relevant articles were retrieved from Medline, Scopus, and Cochrane according to PRISMA guidelines. A systematic review and meta-analysis were conducted on the clinical characteristics, management, and outcomes. RESULTS: A total of 33 articles containing 957 patients who underwent OE for CFLs were included (weighted mean age: 64.3 years [95% CI: 59.9-68.7]; 58.3% were male). The most common lesion was squamous cell carcinoma (31.8%), and the most common symptom was disturbed vision/reduced visual acuity (22.5%). Of the patients, 302 (31.6%) had total OE, 248 (26.0%) had extended OE, and 87 (9.0%) had subtotal OE. Free flaps (33.3%), endosseous implants (22.8%), and split-thickness skin grafts (17.2%) were the most used reconstructive methods. Sino-orbital or sino-nasal fistula (22.6%), flap or graft failure (16.9%), and hyperostosis (13%) were the most reported complications. Regarding tumor recurrences, 38.6% were local, 32.3% were distant, and 6.7% were regional. The perineural invasion rate was 17.4%, while the lymphovascular invasion rate was 5.0%. Over a weighted mean follow-up period of 23.6 months (95% CI: 13.8-33.4), a weighted overall mortality rate of 39% (95% CI: 28-50%) was observed. The 5-year OS rate was 50% (median: 61 months [95% CI: 46-83]). The OS multivariable analysis did not show any significant findings. CONCLUSIONS: Although OE is a disfiguring procedure with devastating outcomes, it is a viable option for carefully selected patients with advanced CFLs. A patient-tailored approach based on tumor pathology, extension, and overall patient condition is warranted.

Imaging spectrum, associations and outcomes in acute invasive fungal rhino-ocular-cerebral sinusitis in patients with COVID-19 pneumonia.

Background: Coronavirus Disease 2019 (COVID-19) has been speculated to enhance mucormycosis infection due to its immune-altering pathophysiology. Early identification of high-morbidity conditions is crucial for optimal treatment and improved outcomes. Methods: A retrospective study was conducted on 63 patients with clinical and microbiological evidence of rhino-ocular-cerebral mucormycosis, who had a history of COVID-19 infection. The clinical, demographic, and imaging data were retrieved and analyzed. Descriptive statistics (mean [SD] and frequency [%]) were used to describe important characteristics across audit cycles. Results: Out of 63 patients, 54 (85.71%) patients had associated comorbidities, with diabetes mellitus being common comorbidity and all patients had received injectable and/or oral corticosteroids. Imaging showed nasal and paranasal sinus, perisinus, maxillary alveolar arch, and hard palate involvement in 62 (98.41%), 33 (52.38%), 5 (7.94%) and 5 (7.94%) patients, respectively. Orbital involvement was seen in 24 (38.10%) patients. Skull base involvement was seen in 11 (17.46%) patients, and intracranial extension of disease was present in 11 (17.46%) patients. A total of 16 patients were on mechanical ventilation, of whom 3 succumbed. The mean (standard deviation [SD]) intensive care unit (ICU) stay was 13.2 days (6.8) for 5 patients who succumbed and 6.4 days (4.6) for 30 patients who survived (P value = 0.008). Conclusion: Cross-sectional imaging not only provides the extent of disease spread but also plays a vital role in providing a surgical roadmap to treating surgeons and in predicting prognosis in patients with invasive fungal infections.

Orbital Exenteration and Reconstruction Using a Free Radial Forearm Flap in Conjunctival Melanoma: Old but Gold.

Conjunctival melanoma is a rare and potentially deadly tumor. Therefore, adequate oncological resection is essential, commonly leading to total orbital exenteration, which causes patients' extensive functional and cosmetic impairment. As a result, it is essential to reconstruct the orbital region post-exenteration to obliterate the cavity, provide adequate and pliable cutaneous covering, and restore a stable vascularized tissue that can withstand adjuvant radiotherapy. In recent years, the techniques used for orbital reconstruction have included the transorbital temporoparietal fascial flap, the anterolateral thigh flap, and local flaps, such as the paramedian forehead flap. A free radial forearm flap is currently not commonly used for orbital reconstruction due to potential donor site morbidity and cosmetic issues. In our case, we report a free radial forearm fasciocutaneous flap that has been utilized with promising surgical outcomes to reconstruct the orbital region following orbital exenteration.

Ten years' blindness of the right eye: A rare presentation of an orbital melanoma.

Benign and malignant orbital tumours develop from the orbit or invade it from the surrounding tissues. Ocular melanoma is a rare but potentially devastating malignancy arising from the melanocytes of the uveal tract, conjunctiva, or orbit. The poor overall survival depends mainly on its high metastatic rate. Signs and symptoms are variables mainly depending on the size of the tumour. Its treatment consists generally of surgery, radiotherapy or both. We report a case of a patient suffering from unilateral blindness for the last 10 years with a recent swelling of the orbit. The pathological analysis described a uveal melanoma. The patient benefitted from a total orbital exenteration with reconstruction using a temporal flap. Thereafter, the patient received adjuvant radiotherapy and immunotherapy. The patient was in complete remission. No recurrence was highlighted after 2 years of follow-up.
