The main aim of this study placed on cadavers was to compare the data related to geniculate ganglion (GG) dehiscence and dimension obtained from computed tomography (CT) with dissection values. ⋯ Our findings based on dissection data suggest that radiologic evaluation of dehiscent GG detection might be erroneous by 25%, which highlights that surgeons should be careful when lifting the dura to prevent GG injury during middle cranial fossa surgical approaches. On the other hand, there was no statistical difference between CT and dissection measurements related to GG dimension.

Conventional laminectomy for spine decompression involves inherent complications resulting from perioperative traumatization of posterior structures. Minimally invasive decompression was developed to address these issues. Full endoscopic spine surgery has shifted the paradigm from disc pathology to spinal stenosis by overcoming the limitation of bony procedures with evolving endoscopic instruments. However, a steep learning curve restricts the development of endoscopic decompression. The purpose of this study is to describe full endoscopic uniportal unilateral laminotomy for bilateral decompression through the interlaminar approach and to evaluate its efficacy and safety in 2 years of follow-up. ⋯ This procedure obtained successful and satisfactory outcomes for patients, and was more feasible for surgeons.

Historically, it is stated that large intracranial tumors, herein defined as a maximum dimension of ≥3 cm or tumor volume ≥14.2 cm3, are not candidates for stereotactic radiosurgery (SRS). We report outcomes of patients with large benign intracranial tumors treated with SRS. ⋯ Despite the historical adage, we find that SRS provides high rates of LC for these large tumors, with rates of ARE similar to historical reports of SRS for smaller benign tumors.

Percutaneous Endoscopic Interlaminar Decompression of Hypervascular Spinal Metastases: Case report.
Percutaneous endoscopic surgery is a common technique used for the treatment of disk herniation and spinal stenosis. In this report, we present a patient who underwent percutaneous endoscopic decompression due to spinal metastasis. ⋯ Percutaneous full-endoscopic interlaminar decompression can be an alternative minimally invasive treatment option in selected patients with radicular pain and neurologic deficit caused by spinal metastasis.

An aneurysm embedded in a pituitary adenoma is rare, and treatment for both the aneurysm and pituitary adenoma is complex and controversial. ⋯ A combined endoscopic endonasal and bilateral subfrontal approach is effective for a pituitary adenoma associated with an ICA-SHA aneurysm.
