Two main surgical techniques are available for corpus callosotomy (CC): conventional microscopic CC and endoscopic CC.1 Microscopic CC is more familiar to neurosurgeons and allows three-dimensional visualization, but it requires a larger craniotomy and has a narrower visual angle in the deep part. Endoscopic CC has only recently been introduced to epilepsy surgery, but it is gaining increasing interest among epilepsy surgeons. The endoscope provides two-dimensional visualization and requires a camera as an additional instrument inserted into the surgical corridor. ⋯ In some cases, this procedure can take a long time. On the other hand, a posterior approach requires less interhemispheric arachnoid dissection, or sometimes none at all, due to the anatomy of the falx cerebri. These reasons have driven the development of a posterior approach for an endoscopic-alone technique.3 Here, we present a 5-year-old girl with medically intractable epileptic spasms that were diagnosed as infantile epileptic spasms syndrome, who underwent endoscopic total CC via a posterior approach to control her seizures (Video 1).

Intraoperative mapping of the nervous system is used to identify "eloquent" cortical areas. In this technical report, we describe a novel way of mapping the somatosensory cortex so that injury to those critical pathways can be avoided. ⋯ Sensory mapping of the cortex is possible with a handheld monopolar electrode. This technique is easy to perform and can help reduce neurological morbidity.

One strategy to increase the availability of neurosurgical services in underserved regions within Sub-Saharan African countries is to create new residency training programs outside of cosmopolitan cities where programs may already exist. In 2016 Tenwek Hospital in rural western Kenya began offering full-time neurosurgical services and in 2020 inaugurated a residency training program. This review highlights the operative epidemiology of the first 5 years of the hospital's neurosurgical department. ⋯ The neurosurgical caseload of a rural hospital in an underserved area can provide not only an adequate neurosurgical volume, but a robust and varied exposure that is necessary for training safe and competent surgeons who are willing to remain in their countries of origin.

Chiari I malformation, marked by severe headaches and potential brainstem/spinal cord issues, often requires surgical intervention when conservative methods fail. This study introduces a minimally invasive surgery (MIS) Chiari decompression technique utilizing a 3-blade retractor, aiming to reduce postoperative discomfort and optimize outcomes. ⋯ The MIS 3-blade flexible retractor technique for Chiari decompression is feasible, provides wide visualization angles of the suboccipital region and C1 arch, allows 2-surgeon work, and minimizes skin and soft tissue disruption. This combination may diminish postoperative discomfort, reduce the risk of surgical site infections, and optimize outcomes.

Deep gluteal syndrome (DGS) is a medical diagnosis in which the pathoanatomy of the subgluteal space contributes to pain. The growing recognition that gluteal neuropathies can be associated with the presence of a bone-neural conflict with irritation or compression may allow us to shed some light on this pathology. This study aims to determine whether the location of the sciatic nerve (SN) in relation to the ischial spine (IS) contributes to the development of DGS. ⋯ The results from this study suggest that the relationship between the IS and SN may play a role in the development of DGS. This may also help establish which patients would benefit more from surgical intervention.
