OBJECTIVE: Suprastomal granulomas pose a persistent challenge for tracheostomy-dependent children. They can limit phonation, cause difficulty with tracheostomy tube changes and prevent decannulation. We describe the use of the coblator for radiofrequency plasma ablation of suprastomal granulomas in five consecutive children from September 2012 to January 2016. METHOD: Retrospective case series at a tertiary medical center. RESULTS: The suprastomal granuloma could be removed with the coblator in all 5 cases...

BACKGROUND: The use of bipolar electrodes for arthroscopic procedures carries a theoretical ex vivo risk of inducing burn injuries. Few studies have measured the in vivo temperatures produced by bipolar electrodes during arthroscopy, and their results are conflicting. The objective of this study was to evaluate the temperature profile within the subacromial space during shoulder arthroscopy with two different electrode systems. HYPOTHESIS: The primary hypothesis was that the two electrode systems produced similar temperature variations and peak temperatures...

REVIEW
Garret W Choby, Peter H Hwang
Coblation is a technology that incorporates bipolar radiofrequency energy to ablate tissue at relatively low temperatures. Its use for sinonasal surgery is actively being investigated, including applications for turbinate reduction, sinus surgery, skull base surgery, and adenoidectomy. Potential benefits include reduction in blood loss, improved endoscopic surgical visualization, and reduction in postoperative pain. The main drawbacks are its relatively high cost, potential adverse effects on functional epithelium, and relative paucity of long-term outcomes...

Spinal metastases are a common and morbid condition in America. Of the 1.6 million new cases of cancer estimated to be diagnosed in the USA in 2015, approximately 5-10 % will develop spinal metastases. This number is expected to increase as the life expectancy of cancer patients increases. Patients with osteolytic spinal metastases experience severe and often debilitating pain, which significantly reduces quality of life. Due to the morbidity of open surgery, particularly in oncologic patients, the treatment paradigm has shifted towards minimally invasive therapy...

OBJECTIVE: Radiofrequency (RF) coblation operates at low temperatures (40-70°C) and allows for ablation, hemostasis, and aspiration, in addition to the lesion excision; thermal damage to the surrounding tissues is thus minimized. Herein, we evaluated the benefit of low-temperature RF coblation treatment of the early-stage glottic cancer. The main aim of the study was to evaluate the feasibility, complications, and efficacy of low-temperature RF coblation as a treatment modality for the early-stage glottic cancer...

Various therapeutic options are available for treatment of recalcitrant plantar fasciitis. Studies using TOPAZ coblation (ArthroCare, Sunnyvale, CA) have had good early results. The current coblation technique involves a surgical incision or breach of the highly specialized plantar fat pad, which can be associated with risks. We describe a novel technique of ultrasound-guided percutaneous coblation with a lateral heel approach. Advantages include precise targeting of the plantar fascia by direct dynamic visualization of the coblation tip, a true percutaneous approach with a needle skin puncture (<5 mm), and preservation of the plantar fat pad by using a lateral heel approach...

The role of inferior turbinate hypertrophy in the reduction of nasal airflow is well established. Although chronic nasal obstruction is not life- threatening, it significantly impairs patients' quality of life, affecting many aspects of daily activities; therefore, patients seek medical intervention. 40 patients were selected (27 males and 13 females) between 27 and 64 years of age with a symptom of nasal obstruction. The patients were divided in two groups: Group 1: coblation, 25 patients (18 males and 7 females); Group 2: radiofrequency, 15 patients (7 males and 6 females)...

Chronic tonsillitis is a common disease, and several different surgical techniques are used to treat this condition. In recent years, techniques such as radiofrequency ablation and coblation have been commonly used for tonsil surgery. In this report, we present the cases of two pediatric patients who developed ptosis, miosis, and enophthalmos (Horner syndrome) after radiofrequency ablation for tonsil reduction and discuss the technique of radiofrequency ablation of the tonsils. In the early postoperative period, miosis and ptosis were observed on the right side in one patient and on the left side in the other patient...

REVIEW
Klaus Stelter
Surgery of the tonsils is still one of the most frequent procedures during childhood. Due to a series of fatal outcomes after hemorrhage in children in Austria in 2006, the standards and indications for tonsillectomy have slowly changed in Germany. However, no national guidelines exist and the frequency of tonsil surgery varies across the country. In some districts eight times more children were tonsillectomized than in others. A tonsillectomy in children under six years should only be done if the child suffers from recurrent acute bacterially tonsillitis...

Debridement is essential in wound treatment to remove necrotic tissue and wound bacteria but may lead to bacteria spread by aerosolization. This study investigated the wound bacterial reduction and bacterial transmission induced by debridement using curette, plasma-mediated bipolar radiofrequency ablation (Coblation®) or hydrodebridement (Versajet®). Full thickness dermal wounds in porcine joint specimens inoculated with S. aureus were debrided with curette, Coblation, Versajet, or were left untreated. During and after debridement, aerosolized bacteria were measured and to assess wound bacterial load, quantitative swab samples were taken from each wound...
