Although anterior cervical diskectomy and fusion (ACDF) is a safe and effective procedure, the complications associated with it cannot be underestimated. The aim of this study was to highlight the potential complications associated with ACDF and the strategies to avoid them. ⋯ ACDF is a relatively safe procedure with very low morbidity and almost no mortality. In this study, the common complications encountered were postoperative dysphagia, dural injury, and hoarseness.

Given their location and slow growth, olfactory groove and planum sphenoidale meningiomas often grow to large sizes before they present with clinical symptoms and pose significant surgical challenges. The goal of our study is to identify which preoperative symptoms and findings on magnetic resonance imaging are correlated with specific postoperative outcomes in order to better counsel patients preoperatively. ⋯ We conclude that tumors larger than 3.4 cm in diameter and those whose posterior edge is within 6-8 mm of the optic chiasm should be recommended for early surgical intervention. In terms of predicting surgical complications, nasal sinus invasion and anterior cerebral artery encasement are associated with greater-risk profiles when surgery becomes necessary. Thus, it is prudent to take these specific variables into consideration when advising patients about the risks of observation and surgery for olfactory/planum meningiomas.

The postoperative time course of redundant nerve roots (RNRs) in patients with lumbar spinal canal stenosis (LSCS) is currently unknown. The purpose of this study is to investigate the relationship between postoperative morphologic changes in detected RNRs and the clinical outcome of patients with LSCS. ⋯ Although most patients with LSCS show postoperative resolution of RNRs detected on MRI, some show persistent RNRs postoperatively. The functional outcome of these patients remains poor even if sufficient expansion of the dural sac is achieved postoperatively.

To evaluate objectively the anatomic areas of the cranial base exposed by a three-dimensional (3D) endoscope-assisted far lateral approach. ⋯ Use of a 3D endoscope allows for minimal resection of the condyle and jugular tubercle, better visualization of the surgical compartments toward the midline, and better in-depth surgical exploration of each intradural compartment. However, the 3D probe is still too large and restricts surgical maneuverability.
