Three-dimensional (3D) endoscopy is an emerging tool in ear-nose-throat (ENT) and skull base surgery with the benefit of providing real-time depth perception. Several investigators have reported that the field of view (FOV) is reduced in 3D endoscopes compared with regular 2-dimensional (2D) endoscopes. Thus, we objectively compared the FOV of 2D and 3D endoscopes. ⋯ The differences in the FOV between the 2D and 3D endoscopes used in ENT surgery were not clinically significant. Thus, the FOV should not be considered a limitation of 3D technology.

Brain metastasis (BM) from breast cancer is increasingly encountered clinically because of the continuing success in the oncological control of the primary disease. Data-driven reports on the surgical treatment of BM from breast cancer are sparse in sub-Saharan Africa. ⋯ Surgical resection is feasible for BM from breast cancer even in low-resource clinical practice. It has a salutary effect on the patients' quality of life.

The treatment for patients with poor-grade aneurysms defined as World Federation of Neurosurgical Societies (WFNS) grade IV-V is still unclear and controversial. In this research, we compared the clinical efficacy and safety between clipping and coiling in the treatment of ruptured poor-grade anterior circulation aneurysms. ⋯ Patients with ruptured poor-grade anterior circulation aneurysms who undergo microsurgical clipping seem to have a lower short-term mortality. Cerebral vasospasm, WFNS grade V, and postoperative aneurysm rebleeding are associated with short-term mortality.

To investigate effects of using a large-sized coil first on embolizing cerebral aneurysms compared with conventional coils. ⋯ The use of a large-sized coil as the first one for embolizing cerebral aneurysms may be a better embolization strategy because it achieves similar initial occlusion rates, decreased packing density, decreased coil numbers and lengths, and reduced recurrence prevalence at follow-up.

Preoperative endovascular embolization of atypical hemangiomas of the spine can reduce intraoperative blood loss. One frequent concern raised about embolizing these tumors is a possible association with arteries feeding the spinal cord, such as the artery of Adamkiewicz. This study aimed to elucidate a relationship between spinal levels affected by atypical spinal hemangiomas and radiculomedullary arteries. ⋯ In this study, spinal levels affected by atypical hemangiomas requiring surgery were associated with radiculomedullary arteries. When performing preoperative embolization, great care must be taken to identify and preserve arteries supplying the spinal cord.
