Neurosurgery skill laboratory with basic and advanced learning should be there in all teaching hospitals. Skills can be transferred from simulation model or VR to cadaver to live surgery. Staged learning (first with simple model to learn basic endoscopic technique, then animal model, and then augmented cadavers) is the preferred method of learning. Although most surveys favor live surgery and practice on animal models and cadavers as the most preferred training model now, in future VR may also become a favored method of learning. This article is based on our experience in over 10,000 neuroendoscopic surgeries, and feedback from over 950 neuroendoscopic fellows or consultants who attended workshops conducted every 6 monthly since 2010. A literature search was done on PubMed and Google Scholar using (neuroendoscopy) AND (learning), and (neuroendoscopy) AND (training), which resulted in 121 and 213 results, respectively. Out of them, 77 articles were finally selected for this article. Most of the training programs typically focus on microneurosurgical training. There is lack of learning facilities for neuroendoscopy in most centers. Learning of neuroendoscopy differs greatly from microneurosurgery; switching from microneurosurgery to neuroendoscopy can be challenging. Postgraduate training centers should have well-equipped neuroendoscopy skill laboratory and the surgical educational curriculum should include neuroendoscopy training.

Once detected, they need to be treated as an emergency due to their potential for morbidity and mortality. Generally, recurrence does not occur in surgery for acute epidural hematoma if adequate hemostasis is achieved. Here, we report a case of atypical postoperative recurrence of an acute epidural hematoma, possibly due to the development and rupture of a TMMA. A 41-year-old man with left acute epidural hematoma after a head injury was referred to our hospital. Emergency craniotomy was performed immediately, and the hematoma was removed. The source of the bleeding was near the fracture site in the middle cranial fossa, and sufficient hemostasis was confirmed. However, a head computed tomography (CT) scan the next day revealed a recurrence of the acute epidural hematoma. Magnetic resonance (MR) angiogram showed an aneurysm with a diameter of approximately 4 mm in the left middle meningeal artery. The recurrence of the acute epidural hematoma appeared to be related to the formation and a rupture of a middle meningeal artery aneurysm, and to prevent subsequent rebleeding, the patient underwent reoperation, and the hematoma and aneurysm were removed. In surgery for acute epidural hematoma, recurrence can be prevented by removing the hematoma and ensuring hemostasis. Although conventional surgery was performed in this case, a repeat of epidural hematoma occurred. A postoperative middle meningeal artery aneurysm had been thought to have developed, ruptured, and caused a repeat epidural hematoma. In treating acute epidural hematoma, a TMMA development should be considered when an atypical clinical course occurs, such as a recurrence of postoperative bleeding.</p>","PeriodicalId":94300,"journal":{"name":"Asian journal of neurosurgery","volume":"19 4","pages":"825-828"},"PeriodicalIF":0.0,"publicationDate":"2024-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11588612/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142741904","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}

Most meningiomas present with an indolent, longstanding history. However, the data on outcomes of emergency surgeries for meningioma is limited. This study aims to present our experience of urgent surgical intervention in patients with meningiomas presenting acutely. We also analyze the factors influencing early neurological outcomes and complications. <b>Materials and Methods</b>  All nonelective meningioma surgeries done on an emergency basis between January 2015 and December 2019 were retrospectively reviewed. Patients' demography, clinical, and radiological details were recorded for analysis. The surgical procedure, complications, and follow-up outcomes were also included for statistical comparison. <b>Results</b>  Forty-four patients qualified for the study with a mean age of 49.4 ± 13.4 years. The average presenting Glasgow Coma Scale (GCS) was 13; 47.7% of cases presented with altered sensorium. The most common lesion location was convexity (25, 56.8%), and the mean tumor volume was 74.1 ± 36.5 mL. Gross peritumor edema with mass effect was seen in 16 patients (36.4%).
