Multicenter Study
Long-term Outcomes of Pulsed Radiofrequency for Supraorbital Neuralgia: A Retrospective Multicentric Study.
Pulsed radiofrequency (PRF) is a percutaneous, micro-invasive, and micro-destructive neuromodulation technology. It has been reported to be useful in the treatment of supraorbital neuralgia (SN). However, the long-term effectiveness and safety of this technique in SN has not been reported yet. ⋯ The performance of PRF for the treatment of SN was confirmed to be favorable in a multicentric, relatively large scale, and long-term perspective.

Hemifacial spasm (HFS) is mainly characterized by paroxysmal involuntary twitches of one side of the facial muscles. We developed an awake CT-guided percutaneous puncture of the stylomastoid foramen for radiofrequency ablation (RFA) therapy for the treatment of hemifacial spasm and successfully used it in our clinic. ⋯ There was no difference in the operation time or efficacy between the 2 approaches. The anterior mastoid approach is easier to perform and is recommended based on our experience.

Pelvic floor dysfunction and its associated symptoms are a common clinical challenge in the cancer population. Despite the noninvasive nature of pelvic floor rehabilitation (PFR) for this condition and the promising clinical results observed with its use, PFR appears to be an underused therapy. ⋯ PFR is an effective tool for treating the pain associated with pelvic floor dysfunction and its related symptoms. This conservative approach can contribute to lowering the use of opiate analgesics.

Various minimally invasive procedures for treating discogenic pain have been reported in recent years. A Disc-FX® system can be used to perform nucleus pulposus (NP) removal, radiofrequency ablation, and annuloplasty under the guidance of x-ray fluoroscopy. However, when a probe tip with focused heat is placed on the intradiscal/subannular area to perform nucleo-annuloplasty using radiofrequency lesioning, thermal injury to the spinal cord or spinal nerves is a concern. ⋯ The results of this study are limited due to the use of a cadaveric spine, which could not reflect the effect of soft tissue such as muscles and connective tissue around the disc. The position of the temperature measuring probe was relatively fixed. This cadaver demonstration was conducted at the L4-L5 level, which is mostly not restricted by the height of the iliac crest. CONCLUSIONS: When performing NP ablation and annular modification, the epidural peripheral temperature should always be kept below 37°C. This preliminary in vitro research using human cadaveric discs showed that radiofrequency maintained the epidural space at a safe temperature during nucleo-annuloplasty.

Percutaneous cervical nucleoplasty (PCN) is a minimally invasive technique used for the treatment of cervical disc herniation. However, if the lesion is located at the neural foramen, complete access and effective neural decompression are often challenging because of the special anatomical condition of the uncovertebral joint, osteophyte, and facet joint of the cervical foraminal space. ⋯ Although PCN for radiculopathy caused by FCDH is thought to have limitations because of the surrounding bony structure, the clinical outcome seemed favorable. If PCN is not contraindicated, it may be a viable treatment option for CR due to FCDH.
