Despite a wide range of surgical procedures, an unresolved debate remains regarding which attempt is optimal for the treatment of colloid cysts in the third ventricle. In this article, we present a new combination of stereotactic and endoscopic techniques. ⋯ The techniques we describe for removal of colloid cysts are safe and effective, even for recurrent cases, and they provide 100% total resection, favorable cognitive outcomes, low risk of recurrence, and low risk of morbidity. The disadvantages of this method are a longer time for surgery and the need for more complex instrumentation compared with conventional endoscopic resection.

Case Reports
Case Series of Anterior Intervertebral Graft Extrusions in Transforaminal Lumbar Interbody Fusion Surgeries.
According to the published reports, revision surgery is sometimes recommended even in patients with asymptomatic anterior lumbar intervertebral graft migrations. The main purpose of this chart review study was to report on the clinical course and outcomes of patients who had anterior intervertebral graft extrusions after transforaminal lumbar interbody fusion (TLIF). ⋯ The risks of additional and highly invasive revision surgery should be weighed against the potential short-term and long-term complications associated with graft extrusions or migrations. It was demonstrated that fusion may take longer but can be achieved, and close observation may be adequate for asymptomatic patients.

The Draf III (modified endoscopic Lothrop) procedure has been proposed to extend the endonasal transethmoidal, transfovea ethmoidalis, and transcribriform approach through the back wall of the frontal sinus. The exposure is time-consuming and increases the risk of cerebrospinal fluid leak, and the indications for use are not well described. There are few data quantifying the advantage it conveys over the approach without the Draf III procedure. ⋯ This study quantifies the increased field of view provided by the Draf III procedure during anterior skull base dissection. Recommendations for preoperative examination of radiographic evidence are provided to help identify which individuals would benefit from the additional exposure.

Extraforaminal lumbar disc herniation (EFLDH) accounts for 7%-12% of all lumbar disc herniations. We report on a surgical technique for EFLDH, which requires only minimal resection of the facet joint and also allows access to the preforaminal space, if necessary. ⋯ Disc fragment herniectomy through a facet joint quadrantectomy for EFLDH is a safe and minimal invasive technique resulting in very satisfactory results. Preservation of facet joint stability and the possibility to convert to a classic approach to reach for preforaminal components, if necessary, are major advantages of this technique.

Nonfunctioning pituitary adenomas are the most common pituitary adenomas in adults and cause significant morbidity unless adequately treated. ⋯ Nonfunctioning pituitary adenomas present frequently as mesoademonas and giant adenomas. Patients with these tumors may have subclinical visual or hormonal deficits at the time of diagnosis. Early and effective surgical treatment is essential for rapid recovery of visual and/or hormonal deficits, particularly in symptomatic cases.
