PURPOSE: To use radiofrequency ablation (RFA) in the resection of C4 cervical chordoma with a giant paravertebral tumor mass to achieve tumor-free exposed margins and perform a gross total excision. METHODS: A gross total excision using combined posterior and anterior approaches was performed. In the posterior stage, the C4 posterior arch was removed and the C4/C5 nerve roots and vertebral artery were released from the tumor. In the anterior stage, the giant soft mass of tumor from C3 to C6 was treated with RFA to make it shrink and solidify visually to achieve tumor-free exposed margins before resecting the tumor...

RATIONALE: Long-term recurrence rate of differentiated thyroid carcinoma has been reported to be as high as 30%. Repeat surgery may be challenging due to normal tissue plane distortion secondary to postoperative fibrosis, especially for small-sized recurrences. Recently, radiofrequency ablation (RFA) has been suggested to be a safe and effective alternative for high-risk patients or those who refuse surgery. Nonetheless, the efficacy of RFA remains questionable for densely calcified lymph nodes, which would have an increased likelihood of leaving residues after RFA...

PURPOSE OF REVIEW: Cervicogenic headache (CHA) is a secondary headache which has a source in the upper cervical spine. Many traditional analgesic choices lack good efficacy in managing the associated pain. As a result, in management of CHA, radiofrequency ablation (RFA) or pulse radiofrequency (PRF) has been tried with success. Our study investigated the use of RFA and PRF for the management of CHA. RECENT FINDINGS: In the present investigation, a review of the literature was conducted using PubMed (1966 to February 2017)...

BACKGROUND: Understanding the characteristics of the middle cervical sympathetic ganglion (MCSG) may minimize procedure-related complications and maximize efficacy during surgery or ultrasound (US)-guided procedures. The location and detection rate of the MCSG were variable in small population studies. Therefore, a large population study or meta-analysis could give more information about the MCSG. OBJECTIVES: We aim to review the published literature and evaluate the anatomical features of the MCSG, including the detection rate, location, size, and a normal variation, and to review the clinical relevance of MCSG for procedures including, US-guided ganglion block, ethanol ablation (EA), or radiofrequency ablation (RFA)...

BACKGROUND AND AIM: Symptomatic cervical heterotopic gastric mucosa, also known as cervical inlet patch (CIP), may present in various shapes and causes laryngopharyngeal reflux (LPR). Unfortunately, argon plasma coagulation, standard treatment of small symptomatic CIP, is limited in large CIP mainly because of concerns of stricture formation. Therefore, we aimed to investigate radiofrequency ablation (RFA), a novel minimally invasive ablation method, in the treatment of CIP focusing on large symptomatic patches...

A 12-year-old girl presented with a history of cervical mass, and one week of throat discomfort and dyspnea. Five years ago, the patient was diagnosed as Hashimoto's thyroiditis and hyperthyroidism; she received antithyroid drug treatment, but the result was not satisfactory. B-ultrasonic showed that the size of thyroid gland was 8.1 cm×3.2 cm in the left and 8.2 cm×4.8 cm in the right. After iodine 131 combined with radiofrequency ablation (RFA) treatment, throat discomfort and recumbent breathing difficulties disappeared, and B-ultrasonic showed that the size of thyroid reduced to 2...

Motor map reorganization is believed to be one mechanism underlying rehabilitation-induced functional recovery. Although the ipsilesional secondary motor area has been known to reorganize motor maps and contribute to rehabilitation-induced functional recovery, it is unknown how the secondary motor area is reorganized by rehabilitative training. In the present study, using skilled forelimb reaching tasks, we investigated neural network remodeling in the rat rostral forelimb area (RFA) of the secondary motor area during 4weeks of rehabilitative training...

BACKGROUND AND AIMS: The cervical inlet patch (CIP) is an area of heterotopic gastric mucosa at the proximal esophagus, which can secrete both acid and mucus. Attributable symptoms include chronic globus sensation and sore throat. Previous studies have demonstrated improvement in symptoms after ablation using argon plasma coagulation. Our aim was to assess a through-the-scope radiofrequency ablation (RFA) catheter for ablation of symptomatic CIP. METHODS: Ten patients with endoscopically and histologically proven CIP and symptoms of globus or sore throat were included in the study...

BACKGROUND CONTEXT: Radiofrequency ablation (RFA) is emerging as a complementary treatment for vertebral metastases. Traditional RFA induces frictional heating leading to local tissue necrosis but often yields small, incomplete, and inhomogeneous zones of ablation in bone. We have developed a new bone-specific RFA electrode that uses a nontraditional frequency (27.12 MHz) and geometry (helical), exploiting a magnetic field and an electric field to generate larger and more comprehensive treatment zones...

Radiofrequency ablation of medial branch nerves is considered a safe and effective treatment for chronic facet joint pain in the cervical, thoracic, and lumbosacral spine. Cooled radiofrequency ablation (C-RFA) is gaining popularity over conventional thermal radiofrequency ablation (RFA) in pain management. However, complications of C-RFA have not been reported in the literature. We present a first report of third-degree skin burn resulting from C-RFA electrode use for the treatment of facet syndrome. A 61-year-old woman (BMI of 21...

Esophageal cancer is the eight most common cancer worldwide and the sixth cause of cancer related death with squamous cell carcinoma (SCC) accounting for almost half of all esophageal cancers. Persistent human papilloma virus (HPV) infection has been suspected to play an active role in esophageal carcinogenesis but a clear association has not still been proven and no specific indications or guidelines for possible endoscopic and surgical therapeutic approaches to this clinical scenario are available. We report a case of a 62-year-old woman with histological diagnosis of high-grade intraepithelial squamous neoplasia of distal esophagus associated with cytological modifications resembling cervical HPV infection and with a positive INNO-LiPA assay for genotype 16 HPV...

Osteoid osteoma is a relatively common benign skeletal tumor. The traditional standard treatment has been surgical resection of the nidus. Recently, computed tomography (CT)-guided radiofrequency ablation (RFA) has gained favor as a more precise alternative due to potentially less bone destruction. However, CT-guided RFA is limited in treatment for osteoid osteoma involving complex anatomic structures such as cervical spine, pelvis, or scapula because of difficulty in approach and proximity to neurovascular structures...
