The value of elective neck irradiation in management of esthesioneuroblastoma: a retrospective study based on propensity score matching.

This study aims to assess the clinical efficacy of elective neck irradiation (ENI) in patients with esthesineuroblastoma (ENB), a rare malignant neoplasm, who are clinically node-negative. We conducted a retrospective analysis of 178 patients newly diagnosed with ENB at our institution between 2009 and 2021. Propensity score matching (PSM) was employed to compare node-negative patients treated with and without ENI. We extensively examined survival outcomes and treatment failure. Of the 178 participants, 149 (83.7%) were lymph node-negative and staged in Modified Kadish A-C. 96 patients underwent ENI treatment, while 53 did not. At baseline, patients who received ENI differed from those who did not in terms of radiotherapy technique, staging, orbital invasion, surgical mode, and chemotherapy. After PSM, 43 pairs were available for analysis. ENI was observed to extend overall survival (OS, 5-year 73.9% vs. 84.0%; 3-year 76.9% vs. 97.1%, p = 0.022), progression-free survival (PFS, 5-year 38.5% vs. 84.6%; 3-year 50.5% vs. 94.5%, p < 0.001) and locoregional relapse-free survival (LRFS, 5-year 42.7% vs. 84.6%, p = 0.023; 3-year 57.3% vs. 94.5%, p < 0.001) in node-negative ENI patients. Failure pattern analyses revealed that ENI, which included level Ib, II, VIIa, significantly reduced the treatment failure rate. Furthermore, ENI did not significantly impact the prognosis of T1-2 patients, indicating potential clinical value of ENI in T3-4 patients. Our findings suggested that ENI decreased regional failure and significantly enhanced LRFS and PFS. ENI may be considered as an integral part of the initial treatment strategy for locally advanced node-negative ENB patients.

Optimizing surgical approaches for lacrimal gland adenoid cystic carcinoma to minimize cross-organ invasion.

To evaluate the outcomes of eye-sparing surgery for lacrimal gland adenoid cystic carcinoma and the impact on tumor recurrence and orbital integrity. The study enrolled four patients with recurrent lacrimal gland adenoid cystic carcinoma. The outcome focused on the relevance of the integrity of the lateral orbital wall to the occurrence of extraorbital metastasis in the local recurrence of lacrimal gland adenoid cystic carcinoma. Three patients underwent eye-sparing surgery via lateral orbitotomy without postoperative radiotherapy, and one patient who underwent eye-sparing surgery via sub-brow approach. These four patients all demonstrated a recurrence involving the invasion of extraorbital tissues as metastatic form through surgical bone seams. Preserving intact orbital bone tissue is crucial for mitigating direct cross-organ metastasis of lacrimal gland adenoid cystic carcinoma. The findings suggest avoiding the lateral orbitotomy approach with no or limited orbital bone wall invasion.

Biphenotypic Sinonasal Sarcoma with Orbital Invasion: A Literature Review and Modular System of Surgical Approaches.

Background: Biphenotypic sinonasal sarcoma is a rare low-grade tumor arising from the sinonasal tract, featuring locally aggressive biological behavior, with a tendency to invade the orbit and skull base. There are no defined guidelines of treatment; thus, the management varies among different institutions. The aim of the present study is to provide a modular system of surgical approaches according to the lesion pattern of growth from a literature review. Materials and Methods: A comprehensive and detailed literature review on the PubMed and Embase online electronic databases on biphenotypic sinonasal sarcoma with orbital invasion was conducted. A personal case exhibiting peculiar features was also added. Demographic (patient's sex and age), clinical (presenting symptoms and time to treatment), neuroradiological (anatomical origin and pattern of growth), and treatment (type of treatment, surgical approach, extent of resection, peri- and postoperative complications, and adjuvant therapies) data, as well as clinical outcome, recurrence rates, and overall survival, were analyzed. Results: Thirty-one patients harboring biphenotypic sinonasal sarcoma with orbital invasion were identified. Tumors mainly affected female patients (66.7%) and a middle-aged population (median 55.2 years old). Simultaneous skull base involvement occurred in most cases (80.6%). Surgery was performed in all but one case (97%), as unique treatment (59%) or in association with radio-(23.5%) and/or chemotherapy (5.9%/2.9%), allowing for gross total tumor resection in most cases (66.7%). The endoscopic endonasal approach was the most adopted surgical corridor (51.7%). The local recurrence rate was 19.3%, and only two cases of tumor-related mortality occurred. Conclusions: Surgery is the only curative treatment, with the main goal to restore/improve/arrest progression of clinical manifestations. The endoscopic endonasal route represents the master approach for lesions confined to the midline. Microsurgical transcranial and endoscopic transorbital approaches have a complementary role for addressing the lesion's component with large intracranial extension or affecting the paramedian aspect of the anterior cranial fossa and superior-lateral orbital compartment, respectively. The approach selection should be made case by case according to the tumor pattern of growth.

Patterns of treatment failure in patients with sinonasal squamous cell carcinoma after chemoradiotherapy.

To investigate the failure patterns based on precision radiation treatment and to determine the predictive factors of treatment failure for sinonasal squamous cell carcinoma (SNSCC) patients. This was a retrospective study that included 214 cases of treatment failure from 441 consecutive patients. Two experienced radiation oncologists evaluated the tumour volume of cases with local recurrence. The 5-year overall survival (OS), progression-free survival (PFS) rates, and distant-metastasis-free survival (DMFS) were estimated. Investigations were performed on the factors that predicted local failure or distant metastasis. About 140 (31.7%) patients developed local recurrence, 24 (5.4%) experienced regional failure, and 65 (14.7%) underwent distant metastasis. In-field, marginal, and out-of-field failures occurred in 55.7% (78/140), 33.6% (47/140), and 10.7% (15/140) of patients with local recurrence, respectively. In logistic regression analysis, factors statistically significant for total local failure included treatment mode (P < .01), chemotherapy (P < .01), and surgical margins (P < .01). Primary tumours with poor differentiation (P = .018) and R2 resection margin (P = .009) were more prone to develop distant failure. The 5-year OS, PFS, and DMFS rates were 57.8%, 52.0%, and 56.7% for the whole cohort. In univariate and multivariate analysis, the skull base involvement was an independent predictor for poorer OS and PFS; orbital invasion was an independent predictor for poorer OS. Local recurrence and distant metastasis were the most common failure modes. Treatment mode, chemotherapy, and surgical margins were related to local recurrence. Poor differentiation and R2 resection margin were predictors for distant failure. Local recurrence is the most common failure pattern in patients with SNSCC who accepted chemoradiotherapy, and marginal and out-of-field failures occurred in 44.3% of patients with local recurrence.

Searching For Ideal Definite Treatment of Sinonasal Squamous Cell Carcinoma with Orbit Invasions.

Sinonasal squamous cell carcinoma (SqCC) often invades the orbit. Treatment of sinonasal cancer invading orbit can vary depending on the medical center and the extent of the invasion. The definitive treatment strategy, whether it involves preserving the orbit or not, varies on a case-by-case basis and leads to different outcomes. Currently, a multimodal treatment approach, which includes surgery, chemotherapy (CTx), radiotherapy (RT), or concurrent chemoradiotherapy (CCRT), is frequently employed for sinonasal cancers. This study aims to evaluate the prognosis of sinonasal SqCC with orbit invasion in various perspectives. We conducted a retrospective review of patients with primary sinonasal SqCC invading the orbit who were treated at between 2009 and 2018. We examined factors such as the extent of tumor, orbit invasion, treatment strategies, recurrence rates, and survival rates. Overall survival (OS) and disease-free survival (DFS) rates did not significantly differ based on the grade of orbit invasion. When tumor resection with orbit preservation was performed as definitive treatment, DFS was significantly longer compared to cases where surgery was not the definitive treatment (RT, CCRT). There was no significant difference in DFS between those who underwent orbit exenteration and those who underwent tumor resection with orbit preservation as the definitive treatment. Tumor resection with orbit preservation as the definitive treatment appears to be the preferred approach, leading to prolonged DFS while ensuring survival in cases of SqCC with orbit invasion.

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

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). 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. 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. Endoscopic-EOE is a challenging but feasible procedure. Clinical validation is required to assess real-life outcomes.

Endoscopic resection of primary sinonasal mucosal melanoma with orbital invasion: How I do it

Primary sinonasal mucosal melanoma is a rare aggressive malignancy. In this video, a case of a 68-year-old female who presented with diplopia for 2 weeks is described. The present video reports the endoscopic endonasal surgical excision of a primary sinonasal mucosal melanoma. The video contains patient's medical history, preoperative radiological evaluations and step-by-step description of surgical steps of the procedure with the utilization of computer-assisted navigation system.

Non-keratinizing squamous cell carcinoma – A rare variant of sinonasal tract malignancy invading orbit: A case report and review of literature

This case report presents a rare case of orbital invasion from non-keratinizing squamous cell carcinoma (NKCa) of paranasal sinuses. A male patient presented with painful bleeding from a mass near the left eye, blood-stained discharge from the left nostril, fatigue, and weight loss. There was a heterogenous lesion inferomedial to the left eye, inside the left nostril, and in the oral cavity. Palpable neck lymph nodes, computed tomography scan showing a bone-eroding lesion, histopathology, and immunohistochemistry findings suggested malignancy of the NKCa variant. Immediate chemotherapy showed improvement after the first cycle, and the patient is under regular follow-up.

Long-term outcomes after particle radiation therapy in patients with nasopharyngeal adenoid cystic carcinoma

BackgroundNasopharyngeal adenoid cystic carcinoma (NACC) is a relatively rare salivary gland tumor that is generally associated with poor outcomes. High-dose radiotherapy is a key treatment for patients with NACC. This study reported the long-term efficacy and safety of particle beam radiation therapy (PBRT) for NACC.Methods and materialsTwenty-six patients with nonmetastatic NACC who received definitive PBRT alone were included in this retrospective study. The majority of patients (92.3%) had locally advanced disease. Twenty-five (96.15%) patients received intensity-modulated proton radiotherapy (IMPT) followed by a carbon ion radiotherapy (CIRT) boost, and one patient received CIRT alone. Overall survival (OS), local control (LC), regional control (RC), and distant metastasis control (DMC) rates were calculated via the Kaplan-Meier method.ResultsThe median follow-up time was 46.95 months for the entire cohort. Seven patients experienced local recurrence, and one patient experience neck lymph node recurrence. The 3- and 4-year OS, LC, RC, and DMC rates were 100% and 91.7%, 92.3% and 84.6%, 95.8% and 87.8%, and 90.2% and 71.3%, respectively. A total of 91.3% of the patients achieved complete remission of gross tumors at 1 year after PBRT. Severe acute toxicity was observed in only two patients. A grade 4 decrease in visual acuity was observed in one patient with orbital apex invasion. No late grade 3 or 5 toxicity was observed.ConclusionDefinitive PBRT provided a satisfactory 4-year OS for patients with locally advanced NACC. The toxicity was acceptable and mild. Further follow-up is necessary to confirm the efficacy and safety of definitive PBRT for patients with NACC.

Ameloblastic Carcinoma With Orbital Invasion.

Ameloblastic carcinomas are malignant tumors arising from the odontogenic epithelium and defined as having features of ameloblastic differentiation in addition to cytological features of malignancy. Orbital involvement is rare and generally involves invasion of the orbital floor, apex, or soft tissue. This report describes an advanced presentation of ameloblastic carcinoma with orbital invasion and provides a review of the literature. A 58-year-old male presented with a 2-year history of a mid-facial mass, causing intracranial invasion and distortion of most skull foramina, nasopharynx, nasal cavity, and both orbits. Notably, there was an en-plaque pattern of circumferential tracking of the tumor along both orbital walls without invasion beyond the extraconal space, causing compression of the orbital apex and proptosis. Histology demonstrated nests of ameloblastic carcinoma and the advanced tumor was deemed nonresectable, with treatment being palliative.

Dermatofibrosarcoma Protuberans of the Lid with Orbital Invasion: The Challenges of Late Presentation

Background: Dermatofibrosarcoma Protuberans (DFSP) is a very rare painless intermediate to low grade malignancy of the subcutaneous tissue or dermis commonly seen in the young to middle age group and affecting the trunk and proximal extremities. The aim of this report is to present the rare lid affectation of the tumour and the challenges involved in managing a locally invasive tumour in the face of late presentation and financial constraints. This is a case report of a 35-year-old woman who presented a 10 year history of Dermatofibrosarcoma Protuberans (DFSP) of the right lower lid with facial, maxillary, and orbital invasion of the right side. She underwent multiple surgeries, including orbital exenteration. There were limitations in accessing and following primary surgical procedures with radiation therapy and chemotherapy that could have impacted the overall outcome of this case. Managing a DFSP in the presence of late presentation, marked local invasiveness and financial constraints is challenging. A multidisciplinary approach involving social workers must be employed if a cure is to be achieved.

Sinonasal manifestations of granulomatosis with polyangiitis: A retrospective analysis

ObjectiveThis study aimed to examine the characteristics of nasal and imaging findings of sinonasal lesions in granulomatosis with polyangiitis (GPA) patients and how these lesions change over time in both the active and remission phases of the disease. MethodsWe retrospectively reviewed GPA patients with sinonasal lesions who were followed up at our department between January 2005 and December 2020. The following data were collected: age, sex, symptoms at initial presentation, anti-neutrophil cytoplasmic antibody (ANCA) type, and histopathological, nasal (initial and follow-up), and imaging (initial and follow-up) findings. ResultsThis study included 17 patients with GPA aged 30 to 79 years. Computed tomography (CT) of the sinuses showed mucosal thickening in 16 patients, bone thickening in 12, bone destruction in 4, and an orbital invasion mass in 3 at the time of diagnosis. After initiating treatment, mucosal thickening of the sinuses improved in 3 of 16 patients and remained unchanged in 13. Bone thickening at the time of diagnosis remained unchanged in 10 of 12 patients and worsened in 2; 1 patient displayed newly developed bone thickening. Destructive nasal findings on CT were positive for proteinase 3-ANCA. ConclusionsOur study revealed that mucosal thickening, bone thickening, bone destruction, and orbital invasion mass were major CT findings in patients with GPA. Intranasal findings such as granulations, crusting, and necrosis were seen in the active phase; moreover, saddle nose, loss of turbinate, and nasal septal perforation were subsequently seen in the course of the disease. Sinonasal findings of GPA vary depending on the disease stage and period.

Intra-arterial chemotherapy for locally advanced nasal cavity and sinonasal tract cancers

Introduction. Malignant tumors of the nasal cavity and sinonasal tract are rare, less than 3 % of all of the head and neck malignant neoplasm. The leading treatment is combined methods with surgery as a first step. However, operation is limited in a locally advanced process due to requires the use of complex reconstructive techniques and removal of aesthetic and functionally important structures. In this regard, the interest of specialists is understandable in use of organ-preserving techniques with comparable oncological results. Intra-arterial chemotherapy has shown high effectiveness in various localizations of malignant neoplasms, so its use in locally advanced tumors of the nasal cavity and sinonasal tract seems promising.Aim. To evaluate the results of complex treatment of patients with locally advanced cancer of the nasal cavity and sinonasal tract using induction intra-arterial chemotherapy.Materials and methods. The study included 28 from 2017 to 2023 with locally advanced cancer of the nasal cavity and sinonasal tract underwent TPF induction intra-arterial chemotherapy, followed by radiation or chemoradiotherapy. The primary endpoint of the study was survival, secondary – objective response rate, treatment toxicity and the possibility of organ preservation.Results. The median follow-up was 19.1 months. We obtained results for all patients of 1-year overall survival – 85.7 % (T3 – 100 %, T4a – 92.7 %, T4b – 55.6 %), and 1-year progression-free survival – 66.7 % (T3 – 75 %, T4a – 71.4 %, T4b – 50 %), respectively. The response rate after intra-arterial chemotherapy was 85.2 %. Overall survival and progression-free survival did not differ significantly between patients with complete response, partial response, and stable disease. However, in patients with a complete response after chemoradiotherapy, 1-year overall survival was 100 % (p = 0.009) and progression-free survival – 90 % (p &lt;0.001). The main side effect in patients in the study was the development of neutropenia (35.7 %), and occurrence of neurological complications was noted in 10.7 %. Of the 35.7 % of patients with tumor orbital invasion, survival with preserved visual function in the first year of life was 80 %; all patients retained vision; as a result of treatment, not a single patient underwent surgery with exenteration.Conclusion. Induction intra-arterial chemotherapy in treatment of patients with locally advanced cancer of the nasal cavity and sinonasal tract demonstrates high efficiency and a high level of complete responses with a fairly low level of toxicity, and also allows preserve the eye function for the majority of patients.

Transorbital neuroendoscopic surgery for treatment of sphenoid wing meningiomas extending to the cavernous sinus: clinical implications and a technical illustration.

The aim of this study was to evaluate the efficacy and safety of transorbital neuroendoscopic surgery (TONES) in the management of sphenoid wing meningiomas (SWMs) with cavernous sinus and orbital invasion. The authors conducted a retrospective review of 32 patients with SWMs treated at Gazi University using TONES from October 2019 to May 2023. The study includes clinical applications to elucidate the endoscopic transorbital approach. Surgical techniques focused on safe subtotal resection, aiming to minimize residual tumor volume for subsequent radiosurgery. Data were collected on patient demographics, tumor characteristics, surgical procedures, complications, and postoperative outcomes, including radiological imaging and ophthalmological evaluations. Surgical dissections delineated a three-phase endoscopic transorbital approach: extraorbital, intraorbital, and intracranial. In the clinical application, gross-total resection was not achieved in any patient because of planned postoperative Gamma Knife radiosurgery. The mean follow-up period was 16.3 months. Of 30 patients with preoperative proptosis, 25 experienced postoperative improvement. No new-onset extraocular muscle paresis or visual loss occurred postoperatively. The average hospital stay was 1.15 days, with minimal complications and no significant morbidity or mortality. Total resection of SWMs invading the cavernous sinus and orbit is associated with substantial risks, particularly cranial nerve deficits. TONES offers a minimally invasive alternative, reducing morbidity compared with transcranial approaches, and represents a significant advancement in the surgical management of SWMs, especially those extending into the cavernous sinus and orbit. The approach provides a safe, effective, and patient-centric approach, prioritizing subtotal resection to minimize neurological deficits while preparing patients for adjunctive radiosurgery. This study positions TONES as a transformative surgical technique, aligning therapeutic efficacy with neurovascular preservation and postoperative recovery.

Neoadjuvant Chemotherapy Alone or Combined with EGFR-Directed Targeted Therapy or Anti-PD-1 Immunotherapy for Locally Advanced Lacrimal Sac and Nasolacrimal Duct Carcinomas

ABSTRACT Background/aims We describe our findings in patients with locally advanced lacrimal sac and nasolacrimal duct (NLD) carcinoma who received neoadjuvant systemic therapy. Methods We identified patients with locally advanced primary lacrimal sac/NLD carcinoma treated with neoadjuvant systemic intravenous therapy at our institution during 2017–2019. Results The study included seven patients, four men and three women; the mean age was 60.4 years (range: 43–76). All patients had locally advanced disease with significant orbital soft tissue invasion with or without skull base invasion making eye-sparing surgery not feasible as an initial step. Three patients had poorly differentiated squamous cell carcinoma; two, invasive carcinoma with basaloid and squamous features; one, high-grade carcinoma with features suggestive of sebaceous differentiation; and one, undifferentiated carcinoma. The neoadjuvant regimens were cisplatin and docetaxel (n = 1); carboplatin and docetaxel (n = 1); paclitaxel and cetuximab (n = 1); carboplatin, paclitaxel, and cetuximab (EGFR inhibitor) (n = 2); cisplatin, docetaxel, and pembrolizumab (anti-PD-1 immunotherapy) (n = 1); and carboplatin, paclitaxel, and pembrolizumab (n = 1). All patients had radiologic disease regression, and one patient had radiologic near-complete response. After neoadjuvant therapy, all patients underwent wide local excision and adjuvant concurrent chemoradiation. Two patients had a complete pathologic response. At a median follow-up period of 13 months after chemoradiation (range, 8–54 months), all patients were alive without evidence of disease. One patient had nodal metastasis treated with lymph node dissection and adjuvant chemoradiation. Conclusions Neoadjuvant systemic therapy can shrink tumors in patients with locally advanced primary lacrimal sac/NLD carcinoma with orbital or skull base invasion.

Advanced Periocular Basal Cell Carcinoma with Orbital Invasion: Update on Management and Treatment Advances.

Basal cell carcinoma (BCC) is the most frequent malignant periocular tumor. It is associated with exposure to ultraviolet radiation, and its incidence is gradually increasing. It may occasionally display more aggressive behavior and result in orbital or intracranial invasion. Mortality from periocular BBC with orbital invasion is very low, but the associated morbidity can be significant, from disfigurement to blindness. Traditionally, these cases have been treated with orbital exenteration or with radiotherapy (RT), but in recent years, hedgehog pathway inhibitors (HPIs) have emerged, are effective in more serious cases, and are used primarily or combined with surgery, changing our perspective on the management of these patients. We studied 24 cases of periocular BCC with orbital invasion, some primary and others recurrent, which were treated between 2011 and 2021 in the same hospital. All patients had clinical or radiological evidence of orbital invasion. Orbital exenteration was performed on 9/24 of the patients (1 received vismodegib after surgery), and 12/24 were treated, surgically preserving the eyeball, with 3 of them receiving adjuvant vismodegib. Three of the twenty-four patients were treated exclusively with vismodegib (Erivedge®, Genentech). One patient died due to poor tumor evolution, but the rest evolved favorably and they have had no recurrences. Vismodegib was generally well tolerated, except for in one patient who discontinued treatment due to the side effects. In advanced BBC with orbital invasion, mutilating surgical treatments such as exenteration or potentially vision-threatening treatments such as RT remain as options. In recent years, however, very promising new medical therapies have emerged, such as HPI, which can be used effectively instead of surgery or in combination with it, preserving the eye and vision, which implies a new approach to treatment.

Uncommon bilateral orbital lesion in leukemic patient: is it cutis leukemia, celullitis or both?

Introduction : Acute Myeloblastic Leukemia can infiltrate any parts of the body including the orbit and periocular area. This article was aimed to report uncommon sign of cutis leukemia representing as orbital cellulitis.&#x0D; Case Illustration : Male, 35 yo with chief complained progressive lesion in his bilateral upper and lower eyelid since 4 days before admission. He felt pain and stingy sensation around lesion. There was history of toothache. He was diagnosed with acute myeloblastic leukemia since 2 month before. Ophthalmology examination showed his visual acuity was 6/6 in both eyes with good ocular motility.His bilateral upper and lower eyelid were edematous and spasm with multiple vesicles, papule and pustule. Conjunctival injection was found in both eyes. The reminder of ophthalmology examination was unremarkable. There were other hyperemic nodules in left mandibulae and right mastoid bone. Laboratory examination showed increased leukocyte, procalcitonin and C-Reactive Protein level. Orbital CT scan revealed edema in cutis and subcutis area in both superior and inferior bilateral palpebra. Board spectrum and anaerobe antibiotic along with steroid were administered intravenously. Biopsy was performed. After two weeks medication, lesion around both palpebra was decreased. Unfortunately, because of his poor systemic condition, he was readministered to our hospital and hospitalized in ICU. He was passed away after 8 days of hospitalization.&#x0D; Discussion : Male patient is more likely to develop orbital infiltration of leukemia, and it necessitates significant morbidity and mortality condition.&#x0D; Conclusion : Leukemia with orbital invasion should bring more awareness from both ophthalmologist and hematooncologist as it indicates more mortality and morbidity.

Full Thickness Skin Graft Procedure for Basal Cell Carcinoma : A Case Report

Introduction : To present a case of basal cell carcinoma (BCC) of the right upper eyelid using a full thickness skin graft (FTSG) procedure&#x0D; Case Illustration : 69 year old woman with the main complaint of a lump on the upper right eye that has been getting bigger and bleeding more and more since 4 years ago. Examination revealed a tumor measuring 22mm x 12mm x 5mm, smooth surface of pearl-like nodules, talengectiasis, madarosis, palpebral retraction towards the medial canthus. The patient works as a farmer. Wide excision of the tumor and FTSG procedure was performed from the right infraclavicular area, histopathological results of basal cell carcinoma tumor.&#x0D; Discussion : BCC accounts for 90% of malignant eyelid tumors. The biggest risk factor for BCC is UV exposure. BCC rarely metastasizes but orbital invasion occurs in approximately 2%. This patient underwent an FTSG procedure. The graft was taken from the infraclavicular area. One of the key factors for graft success is revascularization of the graft area.&#x0D; Conclusion : FTSG procedure for BCC can give good results. The risk after the procedure is sometimes difficult to predict so that it can become difficult in graft attachment and even failure in attachment to the excision area can occur. This patient was under close observation due to a hematoma under the graft skin.

Survival Analysis and Prognostic Factors After Endonasal Resection of Advanced Olfactory Neuroblastomas: A Single Institution Experience.

To explore the prognostic factors in patients with advanced olfactory neuroblastoma (ONB) underwent endoscopic surgery. Retrospective medical records were reviewed of patients with pathologically proven ONB who underwent endoscopic surgical resection. Clinicopathological characteristics including patient demographics, treatment, complications, follow-up, and outcomes were analyzed. Kaplan-Meier overall survival (OS) and disease-free survival (DFS) curves were plotted. Univariate and multivariate Cox regression models were used to determine prognostic factors. Eighty-five patients with Kadish stage C ONB were examined. According to the various staging systems used, most patients harbored modified Kadish stage C (78.8%). Twenty-six patients (30.6%) underwent bony skull base resection, 11 (12.9%) underwent dura resection, and 24 (28.2%) underwent additional intracranial resection that included the olfactory bulb and duct. Median follow-up was 39 months. Five-year OS and DFS rates were 83.7% and 74.9%, respectively. Five-year OS was 100% in patients treated with bony skull base resection and 77.5% in those who were not (P = .052). Dura resection did not improve OS. Multivariate Cox regression analysis identified perioperative complications (P = .009), gross total resection (P = .004), orbital invasion (P = .014), postoperative radiotherapy (P = .030), and bony skull base resection (P = .019) as independent prognostic predictors. For patients with advanced ONB, endoscopic surgery in conjunction with radiotherapy and chemotherapy is effective and safe. Dura resection should be performed with caution in selected patients to balance survival and complications. Postoperative radiotherapy is important to improve OS and DFS.

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.
