Abstract
OBJECTIVE Internal nasal valve dysfunction is a prevalent cause of nasal obstruction. This systematic review, along with a Meta-analysis, evaluated the efficacy of temperature-controlled radiofrequency device (RFD) treatment in alleviating nasal obstruction by rectifying nasal valve collapse. DATA SOURCES A comprehensive review of studies retrieved from PubMed, SCOPUS, Embase, Web of Science, and Cochrane databases (up to December 2022) was conducted. REVIEW METHODS We included studies that evaluated the quality of life and nasal obstruction scores before and after RFD treatment. In addition, sham-controlled studies were analyzed. RESULTS In total, 451 patients across 8 studies were included in the analysis. Patients who underwent RFD treatment reported a significantly enhanced quality of life 24 months after treatment compared to pretreatment scores. The rates of clinically improved states and positive responses regarding quality of life after treatment were 82% and 91%, respectively. Moreover, the disease-specific quality of life, as assessed by the Nasal Obstruction Symptom Evaluation score, significantly improved. CONCLUSION RFD may help improve nasal obstruction symptoms. Further randomized clinical studies on larger cohorts are essential to substantiate its efficacy in enhancing nasal valve function.

Abstract
Background The objective of this study was to evaluate long-term symptom improvements in patients with nasal airway obstruction (NAO) secondary to nasal valve collapse (NVC) following minimally invasive temperature-controlled radiofrequency (TCRF) treatment. Methods A prospective, single-arm, multicenter study in patients >18 years with NAO due to NVC. Inclusion criteria were response to nasal valve dilation (e.g., modified Cottle maneuver) and baseline Nasal Obstruction Symptom Evaluation (NOSE) Scale score ≥60. Patients were treated in the nasal valve region with a TCRF device and followed through 2 years. A responder was ≥20% reduction NOSE Scale score or ≥1 reduction in severity class. Results A total of 122 patients were treated and 91 reached 2 years. The mean baseline NOSE Scale score was 80.3 (95% CI, 78.1-82.6). The adjusted mean change in score at 2 years was -45.8 (95% CI, -53.5 to -38.1), p < 0.001; a 57.0% improvement. The 2-year responder rate was 90.1% (95% CI, 82.3%-94.7%). Significant and sustained symptom improvement was achieved in subpopulations based on sex, age, body mass index, baseline NAO severity, nasal surgery history, NVC mechanism, septal deviation, and other anatomic contributors of NAO. No serious adverse events with a relationship to the study device and/or procedure were reported. Conclusions Minimally invasive TCRF device treatment of the internal nasal valve for NAO is well tolerated and leads to significant and sustained improvement in NAO symptom severity through 2 years, including in patients with both static and dynamic NVC, septal deviation, turbinate enlargement, or prior nasal surgery. Level of Evidence 2b.

Abstract
Question Is temperature-controlled radiofrequency device treatment of the nasal valve safe and associated with improvement in symptoms of nasal airway obstruction through 12 months postprocedure? Findings At 12-month follow-up of 108 patients treated in a randomized clinical trial with 3-month crossover available to patients in the index sham control arm, patients in the combined active treatment group exhibited a sustained improvement in symptoms over baseline, measured by the Nasal Obstruction Symptom Evaluation Scale. Meaning Temperature-controlled radiofrequency device treatment of the nasal valve was associated with a sustained improvement in symptoms of nasal airway obstruction through 12 months. Importance Nasal valve collapse is a primary cause of nasal airway obstruction (NAO). Patients with NAO and nasal valve collapse experience a variety of symptoms that lower their quality of life, such as nasal congestion, headache, sleep disturbance, daytime sleepiness, and snoring. Objective To determine if active treatment of the nasal valve with a temperature-controlled radiofrequency (TCRF) device, previously demonstrated superior to a sham procedure at 3 months, was safe and associated with sustained improvements in symptoms of NAO through 12 months. Design, Setting, and Participants In a prospective, multicenter, single-blinded, randomized clinical trial, patients in 16 centers in the US with index procedures between August and December 2020 were assigned to TCRF device treatment of the nasal valve or a sham control procedure (no RF energy). Patients had a baseline Nasal Obstruction Symptom Evaluation (NOSE) Scale score of 55 or greater with nasal valve collapse as the primary or substantial contributor to NAO. After primary end point evaluation at 3 months, eligible patients in the sham control arm crossed over to active treatment. Data analysis was performed between April and May 2022. Interventions Patients were treated bilaterally with the TCRF device at 4 or fewer nonoverlapping areas on the nasal mucosa at the junction of the upper and lower lateral cartilage on the lateral nasal wall. Main Outcomes and Measures The primary end point measure was responder rate, defined as 20% or greater reduction in NOSE Scale score or 1 or greater reduction in NOSE Scale clinical severity category. Results A total of 108 patients received active treatment (77 as index active treatment, 31 after crossover). The mean (SD) age of patients was 48.5 (12.3) years; 66 (61.1%) were women. The combined group of patients receiving active treatment had a mean baseline NOSE Scale score of 76.3 (95% CI, 73.6-79.1). At 12 months (n = 88), the responder rate was 89.8% (95% CI, 81.7%-94.5%). The NOSE Scale score improved from baseline (mean change, −44.9 [95% CI, −52.1 to −37.7]). No device/procedure-related serious adverse events were reported. Conclusions and Relevance In this follow-up of a cohort from a randomized clinical trial, the minimally invasive TCRF device, previously demonstrated to be superior to a sham procedure, was safe and associated with improvement in symptoms of NAO through 12 months postprocedure.

Abstract
Capacitive-resistive electric transfer (CRET) therapies have been proposed as strategies for regeneration of cutaneous tissue lesions. Previous studies by our group have shown that intermittent stimulation with 448 kHz CRET currents at subthermal densities promotes in vitro proliferation of human stem cells involved in tissue regeneration. The present study investigates the effects of the in vitro exposure to these radiofrequency (RF) currents on the proliferation and migration of keratinocytes and fibroblasts, the main cell types involved in skin regeneration. The effects of the electric stimulation on cell proliferation and migration were studied through XTT and wound closure assays, respectively. The CRET effects on the expression and location of proteins involved in proliferation and migration were assessed by immunoblot and immunofluorescence. The obtained results reveal that electrostimulation promotes proliferation and/or migration in keratinocytes and fibroblasts. These effects would be mediated by changes observed in the expression and location of intercellular adhesion proteins such as β-catenin and E-cadherin, of proteins involved in cell-to-substrate adhesion such as vinculin, p-FAK and the metalloproteinase MMP-9, and of other proteins that control both processes: MAP kinases p-p38, p-JUNK and p-ERK1/2. These responses could represent a mechanism underlying the promotion of normotrophic wound regeneration induced by CRET. Indeed, electric stimulation would favor completion of granulation tissue formation prior to the closure of the outer tissue layers, thus preventing abnormal wound cicatrization or chronification.

Abstract
OBJECTIVES The aim of this study was to evaluate the efficacy of radiofrequency (RF) energy applications targeting the atrial side of a significant residual leak in patients with acute and chronic evidence of incomplete percutaneous left atrial appendage (LAA) occlusion. BACKGROUND RF applications have been proved to prevent recanalization of intracranial aneurysms after coil embolization, thereby favoring complete sealing. From a mechanistic standpoint, in vitro and in vivo experiments have demonstrated that RF promotes collagen deposition and tissue retraction. METHODS Forty-three patients (mean age 75 ± 7 years mean CHA2DS2-VASc score 4.6 ± 1.4, mean HAS-BLED score 4.0 ± 1.1) with residual leaks ≥4 mm after Watchman implantation were enrolled. Procedural success was defined as complete LAA occlusion or presence of a mild or minimal (1- to 2-mm) peridevice leak on follow-up transesophageal echocardiography (TEE), which was performed approximately 45 days after the procedure. RESULTS RF-based leak closure was performed acutely after Watchman implantation in 19 patients (44.2%) or scheduled after evidence of significant leaks on follow-up TEE in 24 others (55.8%). The median leak size was 5 mm (range: 4-7 mm). On average, 18 ± 7 RF applications per patient (mean maximum contact force 16 ± 3 g, mean power 44 ± 2 W, mean RF time 5.1 ± 2.5 minutes) were performed targeting the atrial edge of the leak. Post-RF median leak size was 0 mm (range: 0-1 mm). A very low rate (2.3% [n = 1]) of major periprocedural complications was observed. Follow-up TEE revealed complete LAA sealing in 23 patients (53.5%) and negligible residual leaks in 15 (34.9%). CONCLUSIONS RF applications targeting the atrial edge of a significant peri-Watchman leak may promote LAA sealing via tissue remodeling, without increasing complications.

Abstract
Background Nasal valve collapse is one of several causes of nasal obstruction. The safety and efficacy of a temperature‐controlled radiofrequency (RF) device for the treatment of the nasal valve for nasal airway obstruction (NAO) has been established in single‐arm studies. The objective of this trial was to compare active device treatment against a sham procedure (control). Methods In a prospective, multicenter, single‐blinded, randomized controlled trial (RCT), patients were assigned to bilateral temperature‐controlled RF treatment of the nasal valve (n = 77) or a sham procedure (n = 41), in which no RF energy was transferred to the device/treatment area. The device was applied to the mucosa over the lower lateral cartilage on the lateral nasal wall. The primary endpoint was responder rate at 3 months, defined as a ≥20% reduction in Nasal Obstruction Symptom Evaluation (NOSE)‐scale score or ≥1 reduction in clinical severity category. Results At baseline, patients had a mean NOSE‐scale score of 76.7 (95% confidence interval [CI], 73.8 to 79.5) and 78.8 (95% CI, 74.2 to 83.3) (p = 0.424) in the active treatment and sham‐control arms, respectively. At 3 months, the responder rate was significantly higher in the active treatment arm (88.3% [95% CI, 79.2%‐93.7%] vs 42.5% [95% CI, 28.5%‐57.8%]; p < 0.001). The active treatment arm had a significantly greater decrease in NOSE‐scale score (mean, −42.3 [95% CI, −47.6 to −37.1] vs −16.8 [95% CI, −26.3 to −7.2]; p < 0.001). Three adverse events at least possibly related to the device and/or procedure were reported, and all resolved. Conclusion This RCT shows temperature‐controlled RF treatment of the nasal valve is safe and effective in reducing symptoms of NAO in short‐term follow‐up.

Abstract
OBJECTIVES The treatment of pediatric airway stenosis represents a major challenge for the otolaryngologist. The aim of this study is to evaluate the use of bipolar radiofrequency plasma ablation (Coblation) in the treatment of pediatric airway stenosis. STUDY DESIGN Retrospective case series. Tertiary care pediatric academic medical center. METHODS The medical records of 6 pediatric patients at Cohen Children's Medical Center from July 2009 to December 2015 were reviewed. All cases involved the use of radiofrequency plasma ablation to address airway stenosis. Patient presentation, surgical intervention(s), post-operative course and complications were analyzed. RESULTS All 6 cases involved pediatric airway stenosis, including glottic stenosis (2), bilateral vocal fold immobility (2), and intratracheal lesions (2). Coblation was used to perform a range of different procedures, including removal of scar/granulation tissue, partial arytenoidectomy, and posterior cordectomy. All patients experienced good results without major complications, perioperative, or post-operative sequellae. CONCLUSION The results of this study suggest that radiofrequency plasma ablation may be an effective endoscopic tool for the treatment of pediatric airway stenosis. Further study and more patients are required as this technique becomes increasingly applied.

Abstract
AbstractBackground:Acquired airway stenosis can be challenging to manage endoscopically because of difficult field visualisation, instrument limitations and the risk of laser fire. At our institution, radiofrequency coblation has been successfully used for the resection of subglottic and tracheal stenosis in adults. This paper presents our experience with this technique.Method:A retrospective case note analysis of all cases of airway stenosis in adults from 2007 to 2012 was performed.Results:Ten adult patients underwent coblation resection for airway stenosis. All lesions were classified as McCaffrey stage I (i.e. less than 1 cm long). Causes of stenosis included: idiopathic stenosis (40 per cent), previous tracheostomy (30 per cent) and endotracheal intubation (20 per cent). Six patients (60 per cent) required a single procedure and 4 (40 per cent) required multiple interventions. All patients reported significant improvement in their symptoms following treatment. All patients were alive at the time of writing and none have required open resection.Conclusion:Radiofrequency coblation is an attractive alternative technique for the treatment of idiopathic or acquired airway stenosis in adults.

Abstract
SUMMARY Pulsed shortwave diathermy, an electromagnetic therapy, has been in clinical use for acute and chronic musculoskeletal pain for many decades. Innovation, miniaturization and advances in technology have allowed for the development of a new generation of shortwave devices that deliver a localized, low fixed dose of shortwave therapy. Clinical research has shown that these novel shortwave devices can be used safely in order to reduce acute and chronic pain, as well as the need for pain medications. Their ease of use and safety profile make low-dose shortwave devices an attractive alternative, or adjunct therapy, to pharmacological-based pain therapies.
