In the literature, there are only short series of radiofrequency of the sphenopalatine ganglion (SPG) to treat chronic refractory cluster headache (CCHr) with variable results. Furthermore, there is no consensus on which methodology to use: radiofrequency ablation (RFA) or pulsed radiofrequency (PRF). ⋯ Radiofrequency of the SPG is a safe, fast, and partially effective method for the treatment of CCHr. Given its low rate of complications and its low economic cost, we think it should be one of the first invasive treatment options, prior to techniques with greater morbidity and mortality, such as neuromodulation.

Adult spinal deformity (ASD) operations are complex and often require a multisurgeon team. Simultaneously, it is the responsibility of academic spine surgeons to train future complex spine surgeons. Our objective was to assess the effect of resident and fellow involvement (RFI) on ASD surgery in 4 areas: 1) perioperative outcomes, 2) length of stay (LOS), 3) discharge status, and 4) complications. ⋯ RFI in ASD surgery was associated with increased operative time, the need for additional transfusions, longer LOS, and nonhome discharge. However, no increase in major, minor, or severe complications occurred. These data support the continued training of future deformity and complex spine surgeons without fear of worsening complications; however, areas of improvement exist.

Medical malpractice litigation is an issue of major concern in neurosurgery, with 19.1% of neurosurgeons facing a claim annually. Neurosurgery possesses the greatest risk of malpractice of any specialty, likely owing to the complex clinical environment and disease severity. In the present study, we have characterized such litigation to determine the common factors that compel plaintiffs to file these claims. ⋯ Malpractice litigation contributes to high overhead and physician burnout and escalates the cost of patient care. We found that benign brain tumors were the most common in litigation and that surgical issues accounted for only a small percentage.

The lateral supraorbital (LS) and minipterional (MP) approaches have been reported for treating intracranial aneurysms as alternative to the pterional approach. We describe our decision making for selecting the minicraniotomy, LS versus MP, for managing noncomplex aneurysms of the middle cerebral artery (MCA), based on the depth of the aneurysm within the Sylvian fissure. ⋯ Our strategy for selecting the keyhole approach based on the depth of the aneurysm within the Sylvian fissure is efficient and safe. We suggest the use of the LS approach when the aneurysm is <15 mm from the M1 origin and the MP approach when the aneurysm is ≥15 mm from the M1 origin.

With application of 3T magnetic resonance imaging (MRI) to functional neurosurgery procedures and given the inherent requirement of millimetric precision, the need to develop a method for correction of geometric image distortion emerged. The aim of this study was to demonstrate clinical safety and practical viability of a correction protocol in patients scheduled to undergo stereotactic procedures using 3T MRI. ⋯ The proposed method can satisfactorily correct geometric distortions in clinical 3T MRI studies. Clinical use of the technique can be practical and efficient after software automation of the process. The method can be applied to all spin-echo MRI sequences.
