These lesions pose significant diagnostic and therapeutic challenges in view of complex orbital anatomy and overlapping clinical presentations. This study aimed to analyze the epidemiology, clinical features, refractive impacts, and management outcomes of orbital tumors, providing insights to optimize diagnosis and treatment strategies.Methods: This study retrospectively analyzes 22 patients who had a presentation of orbital tumors at the Istishari Ophthalmic Eye Hospital between January 2019 and January 2024. Collected data were demographic, clinical, refractive, tumor type, laterality, and management outcome. Advanced imaging studies and histopathological diagnoses confirm the diagnoses. Statistical tests will be applied in assessing the relationship among tumor types, clinical presentations, and refractive changes by means of Analysis of Variance and Chi-square tests.Results: Cavernous hemangioma was the most prevalent tumor (54.5%), followed by adenoid cystic carcinoma and optic nerve meningioma (13.6% and 9.1%, respectively). Proptosis (31.8%) was the predominant symptom. Significant refractive changes were noted across tumor types (P = 0.012). Lateral orbitotomy was the most common surgical approach (68.2%), with adjuvant therapies utilized in 22.7% of cases. Tumors predominantly affected females (54.5%) and the left orbit (77.3%).Conclusion: Orbital tumors present diverse clinical and refractive manifestations, necessitating individualized, multidisciplinary approaches for effective management. This study underscores the importance of advanced imaging, tailored surgical strategies, and the integration of minimally invasive techniques. Future multicenter studies are needed to validate these findings and enhance therapeutic outcomes.","PeriodicalId":94217,"journal":{"name":"Surgical neurology international","volume":"16 ","pages":"62"},"PeriodicalIF":0.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11878717/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143560444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aim to present three cases illustrating the technical nuances and challenges often encountered in Y-stent-assisted coiling (Y-SAC) for such aneurysms and provide an update on technical nuances.Methods: We present three consecutive cases of dysplastic MCA aneurysms, each >10 mm with a wide neck. We successfully performed Y-SAC in all cases on the first attempt using the \"around the world\" technique and used Neuroform Atlas Stent (Stryker Neurovascular, California, USA) as a distal anchor to reduce the microcatheter loop. Immediate final digital subtraction angiography showed adequate occlusion of all aneurysms.Results: All patients tolerated the procedure well and were discharged home on postoperative day (POD) 1 in all cases. The first patient required a second coiling at the aneurysm neck 6 months after initial treatment, with complete protection of the dome. The second patient's 6-month follow-up angiogram showed complete occlusion of the aneurysm with patency of all MCA branches. Unfortunately, the third patient failed to comply with dual antiplatelet therapy after discharge and developed stent thrombosis 3 months postprocedure and passed away.Conclusion: Y-SAC is a reasonable option for large, wide-neck, MCA bifurcation aneurysms in patients who are not fit for microsurgical clipping and/or bypass surgery. Complex endovascular techniques, including aneurysm encircling and the \"Atlas Stent Anchor\" technique, may be necessary to complete the procedure successfully.","PeriodicalId":94217,"journal":{"name":"Surgical neurology international","volume":"16 ","pages":"71"},"PeriodicalIF":0.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11878741/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143560498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report the case of a patient who has performed burr hole surgery for subdural hygroma and chronic subdural hematoma (CSDH) caused by the rupture of an arachnoid cyst.Case description: A 30-year-old man fell off a motorbike and hit his head. Head computed tomography (CT) revealed left MFAC and left subdural hygroma. The subdural hygroma increased over time, and the symptoms of intracranial hypertension developed. Therefore, burr hole operation was performed without the use of a subdural drain. Approximately half a month after surgery, head CT revealed that the density of the arachnoid cyst and subdural hygroma increased and that the subdural hygroma transformed into CSDH. Therefore, a burr hole operation was performed again, and a hematoma cavity drain was left. After surgery, the symptoms of intracranial hypertension improved, and subdural collection did not recur.Conclusion: The increase in CSDH may have disrupted the flap-valve mechanism of the arachnoid cyst and subdural collection. When performing a burr hole operation for a subdural hygroma caused by the rupture of an arachnoid cyst, placement of a subdural drain may be desirable, and consideration of the possibility of CSDH is necessary.","PeriodicalId":94217,"journal":{"name":"Surgical neurology international","volume":"16 ","pages":"67"},"PeriodicalIF":0.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11878727/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143560493","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We evaluated demographic and Patient-Reported Outcomes Measurement Information System (PROMIS) to match cohorts and compare the safety/efficacy of performing CF versus ACDF for 1-2 level unilateral radiculopathy.Methods: This was a retrospective review of 64 patients with similar clinical and radiological data that underwent 1-2 level unilateral CF versus ACDF for cervical radiculopathy. Variables studied included operative revision rates, adverse events, surgical costs, postoperative imaging, PROMIS scores, numeric pain scores, incidence of dysphagia, frequency of vocal cord paralysis, and postoperative neurological status.Results: We found no clinical or radiological differences between patients undergoing ACDF versus CF for unilateral 1-2 level cervical radiculopathy. Surgical differences were observed; ACDF patients demonstrated a 6.25% revision rate versus 0% for CF patients, 40% of ACDF patients reported mild dysphagia versus 0% for CF, 3% undergoing ACDF exhibited vocal cord paralysis versus 0% for CF, and ACDF incurred high implant costs (i.e., $1,836.37 and $2,773.44 for one- and two-level ACDFs) versus 0% for CF warranting no implants.Conclusion: Patients undergoing CF versus ACDF for 1-2 level unilateral cervical radiculopathy required 3.70 fewer postoperative X-rays, 40 min less operative time, and 10.95-h shorter lengths of hospital stay (P < 0.001).

When located in the median or paramedian position, anterior cervical discectomy and fusion or anterior cervical corpectomy and fusion are preferentially selected, whereas posterior approaches are often considered for cases with radiculopathy.Case description: A 40-year-old woman presented with right C6 radicular symptoms without any specific triggering event. She initially experienced symptom relief through medication and an ultrasound-guided nerve block 4 years previously. The symptoms recurred 2 months before presentation and did not improve with conservative treatment. Magnetic resonance imaging revealed a paramedian herniation on the right side, migrating downward from the C5/6-disc level to the inferior border of the pedicle. Posterior endoscopic cervical discectomy (PECD) with partial pediculotomy was performed under general anesthesia with transcranial motor-evoked potential monitoring. The operative time was 56 min.

The femoral nerve branches of the VM and lateralis were exposed anteriorly. The sciatic nerve was exposed posteriorly and passed through a narrow window within the adductor magnus and medial to the femur. The sciatic nerve was then separated into its tibial and peroneal components, which were then coapted to the VM and lateralis motor branches of the femoral nerve.Results: Using the entire tibial and peroneal components of the sciatic nerve, we were able to gain more length and directly coapt the femoral nerve branches without utilizing interposition grafts. The disadvantage of this technique is suturing to a mixed nerve with motor and sensory components, which could compromise functional outcomes. Further studies are needed to determine how the procedure will impact a patient's gait cycle.Conclusion: Clinical application is needed to determine preliminary outcomes before widespread utilization of this technique.","PeriodicalId":94217,"journal":{"name":"Surgical neurology international","volume":"16 ","pages":"73"},"PeriodicalIF":0.0,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11878700/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143560499","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
