Endoscopic approaches are increasingly utilized to treat third ventricular colloid cysts but have been associated with lower rates of complete cyst wall resection. Our objective was to assess the results of colloid cyst resection via an anterolateral endoscopic approach with a dual-instrument technique, with an emphasis on completeness of cyst wall resection. ⋯ High rates of complete colloid cyst resection, with low morbidity, are possible with an anterolateral endoscopic approach with dual-instrument technique. These results support the findings of other endoscopists that show how technical modifications to traditional endoscopic approaches can produce favorable results.

Atypical meningiomas represent 20% of all meningiomas. This retrospective study analyzes the prognostic factors, the effect of different methods of treatments, and the behavior of atypical meningiomas. ⋯ Long-term survival is possible for patients with atypical meningiomas treated with surgery and postoperative RT. Multivariate analysis confirmed that age (<50 years) and total surgical excision were independent prognostic factors for survival. Adjuvant RT reduces tumor recurrence, especially after incomplete surgery.

Conventionally, neuroendoscopic excision of intraventricular tumors has been difficult and time consuming because of lack of an effective decompression system that can be used through the working channel of the endoscope. ⋯ The NICO Myriad is a highly effective tumor decompression system that can be effectively used in a purely endoscopic approach to intraventricular lesions.

Different mechanisms are introduced for various kinds of spine fractures. Falls from walnut trees are a major cause of spine fracture, with a high rate of mortality and significant deficits in young male workers. The aim of this study was to define the rate of cervical fractures and pattern of fractures in falls from walnut trees and to compare with other types of falls in the literature, which seem to have different mechanisms. ⋯ The pattern of fractures was unique to falls from walnut trees, mainly consisting of cervical fractures with quadriplegia and a poor prognosis, and in a young group of workers, which puts a large economic burden on society.
