An epidermoid cyst is a congenital benign tumor and is extremely rare at the presacral region. Only a few cases have been reported in the literature. ⋯ The diagnosis and surgical management of this case are discussed.

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.

Comparative Study
Comparison of Percutaneous Kyphoplasty Versus Modified Percutaneous Kyphoplasty for Treatment of Osteoporotic Vertebral Compression Fractures.
Although percutaneous kyphoplasty (PKP) is performed to restore the vertebral body height and kyphosis in osteoporotic vertebral compression fractures (OVCFs), the regained height may be lost on balloon deflation. This study compares PKP with modified percutaneous kyphoplasty (MPKP) in terms of the clinical outcomes in treating OVCFs. ⋯ MPKP prevents the loss of vertebral height observed with PKP during balloon deflation in addition to providing greater height, Cobb angle recovery, and quality of life compared with PKP in cases of OVCF.

Piezoelectric surgery represents an innovative technique to perform safe and effective osteotomies and is an alternative to traditional bony tissue management using rotating or perforating instruments. We evaluated the safety and feasibility of craniotomies using an ultrasonic device that allows the selective cut of mineralized structures, avoiding damages to the vascular, dural, and parenchymal structures. ⋯ We illustrate the feasibility and safety of a piezosurgical cutter to perform craniotomies. This alternative technique appears to be safe, with excellent cosmetic effects, adding another tool to the neurosurgical armamentarium.

Subaxial cervical spine injuries may be treated with either nonoperative stabilization or surgical fixation. The subaxial injury classification (SLIC) provides 1 method for suggesting the degree of necessity for surgery. In the current study, we examined if the SLIC score, or other preoperative metrics, can predict failure of nonoperative management. ⋯ Management of subaxial spine injuries is complex. In our cohort, SLIC scoring did not adequately predict odds of failure of nonoperative management. Time to evaluation, however, did. We created a modified SLIC score that significantly predicted failure of nonoperative management.
