This approach includes a very limited amount of drilling of the petrous ridge to expose the posterior fossa dura and the superior petrosal sinus to facilitate the subsequent tentorial peeling. Tentorial peeling enables to develop an intertentorial plane between the temporal tentorial leaf (TTL) and the posterior fossa tentorial leaf (PFTL). A linear incision over the posterior fossa dura and the PFTL offers a wide exposure of the neurovascular conflict.Results: M-APIA enables to expose the root entry zone (REZ) of the trigeminal nerve without exposing the temporal lobe or the cerebellum.Conclusion: M-APIA can be considered as a safe alternative to the RSA or STA for trigeminal microvascular decompression (MVD), especially for select cases.

Variations, such as ossified dural septations within the JF, can significantly impact surgical outcomes. The present study investigates the incidence and impact of these ossifications on JF morphometry, providing insights crucial for surgical planning and execution.Materials and methods: We analyzed bilaterally 120 adult dried skulls to assess the presence of accessory foramina (AF), proposing that these represent ossified dural septations. Morphometric measurements of the JF, including height and width, were taken in both cases with and without AF with the use of digital caliper. A thorough literature review was conducted to correlate the findings with clinical implications, and statistical analyses were used to determine significant morphological differences.Results: A complete AF was identified in 2.92% of skulls and an incomplete one in 0.42%. Ossified dural septations were associated with significantly reduced JF height and width. This reduction may hinder intraoperative manipulation, especially of the lower cranial nerves, increasing the potential for complications.Conclusion: The findings underscore the need to recognize JF variants, especially ossified septations, in neurosurgical practice. These variants can complicate surgical approaches to the skull base, highlighting the need for careful preoperative assessment. Future studies are warranted to explore the clinical ramifications of these findings, particularly to patient outcomes in skull base surgeries.","PeriodicalId":16513,"journal":{"name":"Journal of Neurological Surgery Part B: Skull Base","volume":"87 2","pages":"e59-e64"},"PeriodicalIF":0.8,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12971229/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147433589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing transnasal and transcranial approaches to the olfactory bulb (OB) have potential complications. We aim to determine whether transcranial supraorbital keyhole craniotomy (SOKC) provides adequate and safe access to the OB. Secondary outcomes include highlighting specific anatomical obstructions and impacts of patient characteristics.Study design: This is a retrospective cohort study.Setting: This study was conducted at the Tertiary Academic Medical Center.Methods: Fifty fine-cut computed tomographies of the sinuses in consecutive adult patients (50% male) were analyzed. Image processing was performed using syngo.via to assess whether there was a clear path from points on the exterior skull to the anterior or posterior OB. Using five points based on the SOKC technique on the exterior skull, lines were drawn from each point to the ipsilateral anterior and posterior OB resulting in 1,000 pathways. Pathways were reconstructed and analyzed for violations of the orbit, orbital bone, or sinuses.Results: A total of 96% of the subjects had at least one unobstructed pathway to the OB. The route most commonly unobstructed (90%) was 2P (2 cm above the supraorbital notch to posterior bulb). The posterior OB was less obstructed than the anterior (56, 112; p = 0.00002). The most common obstruction was an ipsilateral sinus.Conclusion: The SOKC may be an effective and safe approach for an olfactory implant in many patients. The posterior OB had a clearer approach with less obstruction. By avoiding injury to the nasal mucosa, orbit, sinuses, or traversing the skull base, this approach may prove advantageous over transnasal approaches for olfactory implantation in select patients.","PeriodicalId":16513,"journal":{"name":"Journal of Neurological Surgery Part B: Skull Base","volume":"87 2","pages":"e38-e43"},"PeriodicalIF":0.8,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12971234/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147433725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, only scant studies have analyzed these structures via histological analysis. Furthermore, the histology studies for these structures did not sufficiently evaluate them and their surrounding anatomical relationships. Therefore, this study aims to assess the comprehensive morphology of Gruber's ligament and Dorello's canal.Materials and methods: Histological observation in coronal and sagittal sections and microsurgical observations (using both conventional and inferior approaches) were conducted on Gruber's ligament, Dorello's canal, and related structures.Results: Histological observation revealed that the only extension of the dura was found between the petrous apex and the clivus. Microsurgical dissection using the conventional approach identified a fibrous band, whereas the inferior approach did not reveal any distinct connective tissue other than dura. Our multidirectional approach demonstrated that Gruber's ligament is part of the dura between the petrous apex and clivus. The petrous apex end was artificially separated from the dura along the medial wall of the cavernous sinus. The previously reported variations of Gruber's ligament, such as duplication or absence, can now be explained by our findings.Conclusion: Gruber's ligament is simply a part of the dura at the skull base. The extension of the dura between the petrous apex and clivus, which forms part of a mesh-like structure rather than a distinct ligament, traditionally has been termed Gruber's ligament.","PeriodicalId":16513,"journal":{"name":"Journal of Neurological Surgery Part B: Skull Base","volume":"87 2","pages":"e44-e51"},"PeriodicalIF":0.8,"publicationDate":"2025-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12971235/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147433598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores the applicability of eLTOA in the management of recurrent and newly diagnosed medial temporal lobe gliomas.Methods: Forty patients at our institution underwent eLTOA between 2016 and 2024. There were five surgeries for glioma. Patients were assessed for demographic and clinical data, radiographic characteristics, and histopathological and molecular findings.Results: Four recurrent gliomas required biopsy for diagnosis and molecular genotyping, and one newly diagnosed tumor aimed for gross total resection (GTR). Histologic diagnoses remained unchanged in three recurrent cases (two glioblastoma multiforme and one xanthoastrocytoma). One case was upgraded from oligoastrocytoma Grade II to glioblastoma Grade IV. GTR was achieved in the newly diagnosed tumor, with histology confirming dysembryoplastic neuroepithelial tumor.
