The aim of this study was to examine the role of forehead flaps in the reconstruction of orbital defects after exenteration. Patients undergoing orbital exenteration and reconstruction using median forehead flaps from January 2002 to August 2019 were enrolled in this retrospective study. All the patients were evaluated for wound complications, functional results, and tumor relapse. In total, 105 patients completed the study. Twenty-nine complications in 24 of these patients were assessed. The most common complications were wound dehiscence (11%), partial necrosis of the flap (6%), and bleeding (4%). A major complication occurred in two patients (2%), necessitating surgical correction. Only one patient had a local relapse. Sixty patients received osseointegrated implants, and 58 of them were treated with facial prostheses. The follow-up periods ranged from 6 to 189 months. Thus, forehead flap reconstruction after exenteration is a reliable method with a low complication rate. This technique can be used for primary or secondary reconstruction, and excellent long-term functional results can be achieved. A relapse-oriented follow-up is certainly possible.

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.

Purpose: To evaluate the value and limitation of functional endoscopic sinus surgery alone for the management of post-COVID mucormycosis and need for adjunctive invasive procedure. Materials and Methods: This is a clinical observational study that included a total of 17 patients who underwent FESS for post-COVID mucormycosis from April 2021 to May 2021. These patients reported to our institute with no improvement in their symptoms post-FESS from June 2021 to July 2021. Aggressive Surgical debridement of the involved sinuses, removal of surrounding necrotic bone and orbital exenteration (wherever necessary) was done in these patients. A regular follow-up till six months was done for every patient. Sixteen out of 17 patients did not report with any fresh complaint or recurrence. Results: The study included male and female in ratio of 12:5, with a mean age of 62.5 ± 7.7 years (range: 50–75 years). These patients underwent functional endoscopic sinus surgery, one to two months before reporting to our institute. Post-FESS, there was no improvement in the symptoms. All these patients were given systemic antifungal treatment post-operatively. The specimen was sent for histopathological as well as microbiological examination. All the FESS operated patients required a secondary more aggressive surgical intervention. Conclusion: Post-COVID mucormycosis is an aggressive fungal infection, for which FESS proves inadequate. It requires an aggressive surgical debridement of the necrotic bone along with the debridement of the sinuses. [ABSTRACT FROM AUTHOR]

Background: Congenital intracranial immature teratoma is a rare tumor that is present in the first year of life. It is composed of three embryonic germ layers. These tumors are mainly manifested by hydrocephalus. Radiological investigations and histopathological studies are crucial to evaluating and diagnosing intracranial immature teratoma. Few cases were documented in the literature. Observations: In this case, we highlight a preterm infant born with grade III proptosis and an intracranial space-occupying lesion that was diagnosed as high-grade congenital intracranial immature teratoma by brain MRI and histopathology studies. Neoadjuvant chemotherapy was used after the failure of the initial first attempt of craniotomy and lesion resection. Although, the tumor size increased post-chemotherapy, both intracranial and orbital parts of the lesion were excised efficiently with minimal blood loss, achieving complete tumor resection. Lessons: We demonstrate a case of a rare congenital brain tumor in the pediatric population. We report the diagnostic and treatment challenges besides the effective intraoperative role of neoadjuvant chemotherapeutic agents. To our knowledge, the current case is one of the few published cases of intracranial immature teratoma that presented with ophthalmic manifestations. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to determine the clinical indications for orbital exenteration, demographic profile of these patients, and clinicopathologic correlations in the current times and to compare these results with previous published data. Methods: It was a retrospective study. All exenterations performed at a tertiary eye care center over a period of 20 years (from January 2001 to June 2020) were retrospectively evaluated. Patient records were reviewed to obtain demographic data, presenting symptoms and their duration, laterality, and clinical and histopathologic diagnosis. Results: A total of 352 cases (males:females = 222:130) who underwent exenteration were identified. Patients age ranged from 11 months to 87 years (mean: 43.86 years, median: 50 years). The most common indication for exenteration was found to be eyelid malignancy in 54.36%, followed by retinoblastoma in 18.75% and primary orbital tumors in 14.49%. Out of 156 cases of eyelid malignancies requiring exenteration, squamous cell carcinoma (SCC) was the most common histologic subtype (n = 94, 60.26%), followed by sebaceous gland carcinoma (n = 40, 25.64%) and basal cell carcinoma (n = 20, 12.82%). The most common primary orbital tumors requiring exenteration were adenocystic carcinoma of the lacrimal gland in adults and rhabdomyosarcoma in the pediatric age group. Benign conditions requiring exenteration included fulminant fungal orbital infections and lymphangioma among others. Conclusion: The number of exenterations performed have significantly increased in terms of absolute numbers. However, the ratio of exenteration to other tumor-related surgeries, mainly excision biopsy, has reduced compared to that reported from a previous study. The most common indication in our study remains eyelid malignancy followed by intraocular malignancy. However, SCC has emerged as the most common tumor histologic subtype requiring exenterations.

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. [ABSTRACT FROM AUTHOR]

A 77-year-old Asian female with a history of left orbit exenteration and lid-sparing reconstruction for recurrent sebaceous carcinoma presented with fluid-like sensation of the left orbit. Magnetic resonance imaging (MRI) demonstrated bright T2 signal and a cyst-like cavity within the exenterated orbit. Decision was made to proceed with surgical exploration and excision. A calcified, bone-like cavity was encountered intraoperatively and removed. Histopathology revealed dense fibrous connective tissue with areas of calcification without osseous metaplasia, suggestive of retained blood in the orbit that underwent dystrophic calcification. This case report illustrates a rare occurrence of a bone-like calcific cyst following exenteration. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

The surgical removal of the orbit can be a psychologically traumatic event that may incapacitate patients. The prosthetic rehabilitation of such defects is complex and artistically driven. This case report describes the aesthetic rehabilitation of a patient who had undergone unilateral orbital exenteration due to COVID-19-associated rhino-orbital mucormycosis. This technique uses commonly available materials in the dental clinic and artists' colors for the fabrication of a custom ocular portion of the silicone orbital prosthesis that closely matches the natural eye color of the patient.

Mucormycosis is a disease with a high percentage of mortality. This opportunistic disease is caused by pathogens of the Zygomicota family of the order Mucorales, which affect considerably, mainly immunocompromised patients. We present the case of a patient approached at the Hospital Central Militar de México, diagnosed with rhino-orbito-cerebral mucormycosis, with histopathological report of non-septated hyaline hyphae of 90 º, referring to the aforementioned diagnosis. A multidisciplinary approach to the pathology was carried out with diagnosis, timely medical and surgical treatment, achieving a favorable evolution and prognosis in a condition whose outcome is usually fatal.

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.

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.

Background: Orbital exenteration (OE) is a radical procedure, involving the removal of all orbital contents including orbital fat, globe, conjunctival sac, and part or all of eyelids. It is indicated for malignant tumors of orbital structures not treatable with simple excision or radiotherapy. Lid-sparing OE can be used in cases where the orbital tumors does not involve the eyelids. Aim: The aim of the study is to describe our experience of OE at a tertiary cancer center over 5 years. Materials and Methods: This is a retrospective study. Surgical records of patients, who underwent OE from June 2017 to June 2022, were examined to determine demographics, indications, site of lesions, histological diagnosis, any previous surgery, neoadjunctive and adjunctive treatments, complications, recurrences, and Computed tomography scan/magnetic resonance imaging findings. Settings and Design: This is a descriptive, observational, retrospective study. Statistical Method: Data were entered in Microsoft Excel version 2023 and analyzed in the form of numbers and percentages. Results: A total of 12 cases were included in the study. The mean age of patients was 64.33 years. Presenting symptoms were protrusion of an eyeball in four cases, ocular surface growth in four, decreased vision in one, and eyelid mass in three cases. Three cases were of basal cell carcinoma (25%), one of choroidal melanoma (8.33%), five of invasive squamous cell carcinoma (SCC) (41.67%), two of sebaceous gland carcinoma (16.67%), and one of recurrent optic nerve schwannoma (8.33%). The site of origin of tumor was conjunctiva (n = 5) in 41.67%, eyelid (n = 5) in 41.67%, globe in (n = 1) 8.33%, and orbit in (n = 1) 8.33% of cases. Surgical margins were free of tumor in 10 patients, but positive in two patients. The mean duration of follow-up was 8.08 months with a range of 2–33 months. Conclusions: The most common indication for OE is SCC of conjunctiva. OE is still indicated in some cases of orbital tumors, although recent advances in earlier diagnosis and alternative conservative treatment options are available.

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.

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.

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. [ABSTRACT FROM AUTHOR]

Background: Intraorbital tumor invasion is not uncommon among craniofacial tumors, and is seen in 27% of cases. Craniofacial malignancies account for 3% of all head and neck tumors. Malignant tumors are more common than benign and comprise about 73% of all craniofacial tumors with intraorbital invasion. Their growth is aggressive and invasive, leading to early postoperative recurrence. The survival of patients with malignant craniofacial tumors depends largely on orbital invasion, and patients demonstrating orbital invasion had a 40% survival rate, while patients without had a survival rate of 72%. Patients with total resection of craniofacial tumors (including those with intraorbital extensions) show higher non-recurrence and survival rates than patients without total resection. Orbital exenteration does not provide patients with better survival rates and worsened the quality of life. Purpose: To assess the outcomes of surgical treatment for, and the survival of patients with, malignant craniofacial tumors growing into the orbit. Material and Methods: We reviewed the outcomes of surgical treatment for, and the survival of 94 patients with, malignant craniofacial tumors growing into the orbit. Results: Destruction of the bony orbital wall only (without periorbital adhesion), was seen in 27/94 cases (28.7%), whereas periorbital invasion, in 67/94 cases (71.3%). The tumor was excised completely with visually clear margins in all cases. Patient survival was affected by the degree of orbital invasion. The recurrence rate after surgery for malignant craniofacial tumors growing into the orbit was 44.7% (40/94 patients). Ten patients had a local intraorbital recurrence after surgery for malignant craniofacial tumors growing into the orbit. Conclusion: Periorbital invasion was seen in 71.3% of patients with malignant craniofacial tumors. There was no significant difference in the survival of patients with malignant craniofacial tumors of different histology. Orbital exenteration does not improve survival and recurrence in patients with malignant craniofacial tumors with orbital invasion. In patients with preoperative periorbital invasion and further intraorbital extension, the recurrence rate was more than three-fold higher than in those showing only destruction of the bony orbital wall preoperatively.

Purpose: This study aimed to determine the clinical indications for orbital exenteration, demographic profile of these patients, and clinicopathologic correlations in the current times and to compare these results with previous published data. Methods: It was a retrospective study. All exenterations performed at a tertiary eye care center over a period of 20 years (from January 2001 to June 2020) were retrospectively evaluated. Patient records were reviewed to obtain demographic data, presenting symptoms and their duration, laterality, and clinical and histopathologic diagnosis. Results: A total of 352 cases (males:females = 222:130) who underwent exenteration were identified. Patients age ranged from 11 months to 87 years (mean: 43.86 years, median: 50 years). The most common indication for exenteration was found to be eyelid malignancy in 54.36%, followed by retinoblastoma in 18.75% and primary orbital tumors in 14.49%. Out of 156 cases of eyelid malignancies requiring exenteration, squamous cell carcinoma (SCC) was the most common histologic subtype (n = 94, 60.26%), followed by sebaceous gland carcinoma (n = 40, 25.64%) and basal cell carcinoma (n = 20, 12.82%). The most common primary orbital tumors requiring exenteration were adenocystic carcinoma of the lacrimal gland in adults and rhabdomyosarcoma in the pediatric age group. Benign conditions requiring exenteration included fulminant fungal orbital infections and lymphangioma among others. Conclusion: The number of exenterations performed have significantly increased in terms of absolute numbers. However, the ratio of exenteration to other tumor-related surgeries, mainly excision biopsy, has reduced compared to that reported from a previous study. The most common indication in our study remains eyelid malignancy followed by intraocular malignancy. However, SCC has emerged as the most common tumor histologic subtype requiring exenterations.

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.

Orbital exenteration performed to treat various neoplasms or nonmalignant diseases results in functional, aesthetic, and psychological issues for the patients. If reconstructive surgery is not possible or not desired by the patient, an orbital prosthesis is an excellent choice for cosmetic and psychological rehabilitation. An orbital prosthesis is aesthetic, durable, long lasting, cost-effective, and most importantly retentive. The present case report describes the rehabilitation of an orbital exenteration postsquamous cell carcinoma using a two-part prosthesis, in which retention is achieved by a combination of relining of anatomic undercuts and magnets.

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. [ABSTRACT FROM AUTHOR]

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.

Purpose: To assess the efficacy and safety of bone-anchored dental implant placement at the same time as orbital exenteration compared with delayed implant placement. Materials and Methods: A retrospective comparative study was conducted in a single tertiary care center between December 2003 and December 2017. Patients who underwent bone-anchored implant placement at the same time as orbital exenteration were included (group 1) and compared with patients who underwent delayed implant placement (group 2). The main outcome was the 1-year success rate of implant osseointegration. The secondary outcomes were the 5-year success rate of osseointegration, postoperative complications, and time between orbital exenteration and prosthesis placement. Results: Ten and 11 patients (21 and 22 implants) with a mean follow-up of 50.2 and 48.5 months were included in groups 1 and 2, respectively. Patients in group 1 were significantly older (69.7 vs 61.2 years, P = .026). No significant differences were found between both groups regarding tumor type and location, prior treatments, smoking status, and postoperative radiation beam radiotherapy. The 1- and 5-year success rates of osseointegration were 95.5% and 93.3% in group 1, and 100% and 100% in group 2, respectively (P = .488 and P = .450 between both groups). One implant did not osseointegrate in group 1 due to osteitis. Ethmoidal fistula was the most common postoperative complication found in both groups (P = .670). The mean time between orbital exenteration and episthesis placement was 8 (3 to 14) vs 11 (3 to 15) months in groups 1 and 2, respectively (P = .467). Conclusion: Placing implants at the same time as orbital exenteration is a viable procedure. It reduces surgical morbidity and allows placement of implants in a nonirradiated area.

Simple Summary: Notwithstanding its disfiguring nature, orbital exenteration (OE) has been employed as a surgical intervention for craniofacial lesions, especially in cases of advanced or recurrent tumors. There is a dearth of large studies investigating the clinical and survival outcomes of this procedure. Our study aims to review the literature on the clinical characteristics and outcomes of patients who underwent OE. In the univariable analysis, we found that a positive surgical margin after OE was significantly associated with worse overall survival (OS). Conversely, sex, tumor recurrence, type of OE, and tumor histopathology were not found to exert significant effects on OS. 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. [ABSTRACT FROM AUTHOR]

Rationale: COVID-19 has led to a resurgence in cases of mucormycosis, especially the rhino-orbital form affecting the oral cavity, nasal, orbital and cerebral regions. Patient Concerns: The surgical treatment in this patient led to the exenteration of orbital contents and segmental maxillectomy of the affected side leading to facial disfigurement and inability to masticate. Diagnosis: A combined mucormycosis-associated oro-orbital defect was present leading to a communication between oral and orbital cavities. Treatment: Rehabilitation utilising digital technology for removable prosthesis was planned for the combined orbital and oral defect. Outcomes: The independent intraoral and orbital prosthesis reduced the mobility of the orbital prosthesis while performing functional movements. The advancements in digital technology led to the convenient and resilient fabrication of prostheses for large facial defects. Take-away Lessons: The prosthetic rehabilitation of a continuous orbital and oral defect with a hybrid of both digital and conventional means provided an aesthetic, feasible and financially sound solution to the patient.

Purpose: The second wave of coronavirus disease 2019 (COVID-19) pandemic triggered a mucormycosis epidemic in India. Diabetes mellitus and dysregulated immune response were contributors, and rhino-orbital-cerebral mucormycosis (ROCM) was the most common presentation. It is however not known whether bio-chemical parameters at presentation correlate with stage of ROCM or final outcome in terms of vision or mortality. Methods: This retrospective, hospital-based study included all in-patients of mucormycosis with ophthalmic manifestations at presentation admitted during June 1, 2021 to August 31, 2021. It aimed to evaluate the association between severity of infection, serum levels of HbA1c, ferritin, interleukin-6 (IL-6), C-reactive protein (CRP), and D-dimer levels at presentation and outcome. Results: There were altogether 47 eligible cases having a mean age of 48.8 ± 10.9 years with a male:female ratio of 2.6:1; forty-two (89.4%) had pre-existing diabetes, and five (10.6%) had steroid-induced hyperglycemia. The mean HbA1c among diabetics was 9.7 ± 2.1. HbA1c and serum CRP showed an increase over subsequent stages, which was not statistically significant (P = 0.31). IL-6 values for all stages were similar (P = 0.97). Only serum ferritin levels showed a statistically significant increase over stages (P = 0.04). IL-6 was significantly lower (P = 0.03) in patients who survived, whereas CRP levels were significantly lower in patients who had final visual acuity (VA) better than only perception of light (P = 0.03). Conclusion: Uncontrolled diabetes mellitus is a significant association of ROCM. Serum ferritin levels at presentation best correlate with extent of the disease. CRP levels are best to prognosticate cases that will have sufficient VA to carry on activities of daily living, whereas IL-6 levels are best associated with survival.

Objectives Individuals affected with rhino-orbito-cerebral mucormycosis (ROCM) associated with coronavirus disease 2019 (COVID-19) increased enormously in northern India during the second wave of the novel coronavirus disease. This study determined the demographic and clinical profile including the risk factors in patients presenting to a tertiary care hospital in northern India. Materials and Methods This is a descriptive study involving patients admitted with COVID-19-associated ROCM and were managed from May 2021 to 20th July 2021. Statistical Analysis The data was analyzed using SPSS (IBM SPSS Statistics 20, SPSS Inc., Chicago, Illinois, United States) software and Microsoft Excel (Version 16.49). The chi-squared and Fisher's exact tests were used to compare various outcomes. A p-value of less than or equal to 0.05 was considered to be statistically significant. Results One hundred and seventeen (117) patients (males: 70 [59.8%], females:47 [40.2%]) with the average age of 51.85 ± 12.80 years presented with orbital involvement. Diabetes mellitus was noted in 100 (86.2%) patients. Of the available data from the records, oxygen supplementation for the management of COVID-19 was received by 37/108 (34.3%) patients for a median average duration of 11 days. Forty-eight patients of one-hundred-seventeen (60%) patients were treated with corticosteroids with a median duration of steroid administration being 10 days. The duration between onset of symptoms related to mucormycosis and diagnosis of COVID-19 was 0 to 75 days for 48 patients. Intravenous amphotericin B was administered in all cases. External sinonasal debridement was performed in 90 of 114 (78.9%) patients, retrobulbar amphotericin B injection was administered in 56 of 117 (47.9%), and orbital exenteration was performed in 17 of 117 (14.5%) of cases. Conclusion Administration of corticosteroids and diabetes mellitus seem to be the major underlying causes for the development of COVID-19-associated ROCM. Prompt diagnosis and multidisciplinary management approach are essential for a reduction in mortality.

Abstract Background Mucormycosis is a potentially lethal, angioinvasive fungal infection caused by the Mucoracea family comprising Mucor, Rhizopus, and Absidia species. It is commonly associated with uncontrolled diabetes mellitus, the use of corticosteroids, immunosuppressive drugs, and Covid-19 infection. The occurrence of mucormycosis in an immunocompetent patient is rare. Also, only a few case reports have been published where patients developed mucormycosis with associated malarial infection. Case presentation A young female presented with a 3-weeks history of painful swelling and outward protrusion of the right eye with complete loss of vision. She had a history of P.vivax malaria two weeks before her ocular symptoms. On ocular examination, there was proptosis and total ophthalmoplegia with loss of corneal sensations in the right eye. Hematological examination revealed normocytic normochromic anemia and thrombocytopenia. MRI was suggestive of right-sided pansinusitis and orbital cellulitis with right superior ophthalmic vein thrombosis and bulky cavernous sinus. Nasal biopsy was negative for fungal culture. An emergency surgical debridement of all the sinuses was done with right orbital exenteration. Histopathology confirmed the diagnosis of mucormycosis and the patient improved post-operatively on systemic antifungals. Conclusion Such an association of mucormycosis with malaria infection is rarely reported in the literature and is hypothesized to be a result of immunosuppression caused by malaria. Also, emphasis is laid upon having a high index of suspicion for fungal infection in the setting of pansinusitis even if the risk factors are absent. We hereby report a case of rhino-orbital mucormycosis following P.vivax malaria in a 20-year-old female with anemia and thrombocytopenia.

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.

Purpose: Our aim was to analyze the patients with diabetic rhino-orbital–cerebral mucormycosis that we have treated in our clinic in the last 5 years, and to reveal the altering conditions with COVID-19. Materials and methods: A retrospective study was conducted on 39 rhino-orbital–cerebral mucormycosis (ROCM) patients with diabetes mellitus between 2017 and 2022. The patients were divided into two groups as those associated with and not associated with COVID-19 and compared. Results: Thirty-nine diabetic patients were included in the study, with 15 (38.5%) of them being COVID-19 associated mucormycosis (CAM) group. CAM patients showed higher orbital involvement and cavernous sinus involvement (p = 0.002 and p = 0.013, respectively). The mortality rate in the non-COVID-19 associated mucormycosis (non-CAM) group was statistically higher in patients with intracranial and cavernous sinus involvement (p = 0.015 and p = 0.033, respectively). The difference between the overall survival of the CAM patients and non-CAM patients was not statistically significant (p = 0.741). Conclusions: With COVID-19, progressive mucormycosis accompanied by orbital and intracranial involvement is observed more frequently. However, on the contrary, the mortality rate in COVID-19-associated mucormycosis is considerably lower than expected. The fact that temporary immune suppression can be ameliorated with adequate supportive treatment and liposomal amphotericin-B which can be given to patients in high doses may explain this situation. It has been attained hints that the essential factor in the treatment of COVID-19-associated ROCM is the control of the underlying disease and to be cautious in the decision of early aggressive surgery.

Rehabilitation of a post-exenterated orbital defect is a necessity, to restore a patient's esthetic appearance and help overcome the associated psychosocial stigma. An implant supported prosthesis enjoys a better patient acceptance due to its superior retention and stability. This clinical report highlights the challenges faced in planning, designing and placement of maxillofacial implants in the supra-orbital rim of an exenterated socket post-radiotherapy along with the management of the unexpected complications which developed subsequently. Administration of hyperbaric oxygen therapy, fabrication of a digitally designed surgical guide to ensure predictable implant placement, selection of surface treated implants for better biomechanical anchorage, and a gentler surgical technique for recovery of irradiated hard and soft tissues were measures undertaken during the treatment phase. An effort has been made to point-out the fact that despite the various approaches adopted in an irradiated patient, success of implant placement in such a situation remains a challenge.

AIM: To share clinical pattern of presentation, the modalities of surgical intervention and the one month post-surgical outcome of rhino-orbito-mucormycosis (ROCM) cases. METHODS: All COVID associated mucormycosis (CAM) patients underwent comprehensive multidisciplinary examination by ophthalmologist, otorhinolaryngologist and physician. Patients with clinical and radiological evidence of orbital apex involvement were included in the study. Appropriate medical and surgical intervention were done to each patient. Patients were followed up one-month post intervention. RESULTS: Out of 89 CAM patients, 31 (34.8%) had orbital apex syndrome. Sixty-six (74.2%) of such patients had pre-existing diabetes mellitus, 18 (58%) patients had prior documented use of steroid use, and 55 (61.8%) had no light perception (LP) presenting vision. Blepharoptosis, proptosis, complete ophthalmoplegia were common clinical findings. Seventeen (19.1%) of such patients had variable amount of cavernous sinus involvement. Endoscopic debridement of paranasal sinuses and orbit with or without eyelid sparing limited orbital exenteration was done in most cases, 34 (38.2%) patients could retain vision in the affected eye. CONCLUSION: Orbital apex involvement in CAM patients occur very fast. It not only leads to loss of vision but also sacrifice of the eyeball, orbital contents and eyelids. Early diagnosis and prompt intervention can preserve life, vision and spare mutilating surgeries.

Patients cannot wear ocular prostheses after undergoing orbital exenteration. They require a facial prosthesis to obtain a more favorable appearance, which greatly affects their social life and psychological health. In addition, conventional prosthesis-making processes require substantial time and expense. The economic burden is particularly heavy on children, who may require many prosthesis replacements as they mature. We report a method of fabricating a facial prosthesis by three-dimensional (3D) facial scanning and 3D printed for a 13-year-old girl who underwent partial orbital exenteration for malignant ciliary body medulloepithelioma 2 years ago. The patient's facial contour was captured with a hand-held, point-and-shoot 3D scanner. A facial prosthesis was designed using a mirror image technique with 3D modeling software and 3D printed. The prosthesis was then postprocessed and cast in silicone rubber. An ocular prosthesis was integrated into the facial prosthesis. The prosthesis was retained by prosthetic adhesives. This digitally assisted, impression-free method may lower the cost and effort of making facial prostheses and improve patient comfort, especially for children.

Orbital Exenteration is a major surgical procedure that consists of the removal of the orbital bone, orbital fat, eyeball, and its contents including extraocular muscles. It is an extensive and morbid surgical procedure. Our aim is to systematically review the indications, complications and reconstruction methods utilised for orbital exenteration. An objective electronic database search was conducted in PUBMED Central, MeSH, NLM Catalog, Bookshelf, and PUBMED published in 20 years period from 1999 till 2019. A total of 29 articles were shortlisted for the present review. Most of the studies have eyelid and canthus as most common primary site of malignancy leading to orbital exenteration. Basal cell carcinoma and squamous cell carcinoma being most common pathology. Other intraocular pathology was Retinoblastoma and melanoma. There were various reconstruction methods used by different authors and Sino-orbital fistula was most commonly occurring in majority of studies. Inspite of being a morbid surgery, Orbital Exenteration had acceptable survival and good quality of life. The aggressive pathology that requires orbital exenteration worldwide is mostly periorbital skin, sinus, and intraocular malignancies. The morbidity of the procedure is high with many surgical complications. However, in properly selected patients it can give better outcomes and survival. [ABSTRACT FROM AUTHOR]

Background: Orbital exenteration is a severe and disabling surgical procedure that involves the removal of all orbital contents. Effective reconstruction is crucial to managing the resulting defects. This study aims to propose a reconstructive algorithm utilizing free flaps derived from the lateral circumflex femoral artery (LCFA) system for orbital exenteration defects, based on our clinical experience., Patients and Methods: Patients who underwent orbital exenteration and subsequent reconstruction using LCFA-based free flaps between January 2013 and January 2022 were included in this study., Results: A total of 44 patients underwent orbital exenteration, followed by LCFA free flap reconstruction. The choice of reconstructive technique depended on defect type and dura mater exposure, adhering to the proposed algorithm. The procedures included 20 standard ALT (Anterolateral thigh) flaps, 13 chimeric ALT flaps, 1 SALT chimeric flap with skin grafting, 7 SALT flaps with skin grafting, and 3 buried SALT flaps. Complications were recorded in 10 cases at the recipient site and 2 cases at the donor site., Conclusion: Orbital exenteration presents significant challenges both surgically and reconstructively, with a high risk of local recurrence and postoperative mortality. The reconstruction algorithm using LCFA-based free flaps, as proposed in this study, may guide surgeons in selecting the most appropriate technique, tailored to the specific defect and considering postoperative treatments such as adjuvant radiotherapy., (Copyright © 2024 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Background: Congenital intracranial immature teratoma is a rare tumor that is present in the first year of life. It is composed of three embryonic germ layers. These tumors are mainly manifested by hydrocephalus. Radiological investigations and histopathological studies are crucial to evaluating and diagnosing intracranial immature teratoma. Few cases were documented in the literature., Observations: In this case, we highlight a preterm infant born with grade III proptosis and an intracranial space-occupying lesion that was diagnosed as high-grade congenital intracranial immature teratoma by brain MRI and histopathology studies. Neoadjuvant chemotherapy was used after the failure of the initial first attempt of craniotomy and lesion resection. Although, the tumor size increased post-chemotherapy, both intracranial and orbital parts of the lesion were excised efficiently with minimal blood loss, achieving complete tumor resection., Lessons: We demonstrate a case of a rare congenital brain tumor in the pediatric population. We report the diagnostic and treatment challenges besides the effective intraoperative role of neoadjuvant chemotherapeutic agents. To our knowledge, the current case is one of the few published cases of intracranial immature teratoma that presented with ophthalmic manifestations., Competing Interests: Declarations.
