Abstract Background： Herpes zoster is a common disease mainly affect sensory nerves, but in this report sphenopalatine ganglion (SPG), mainly a parasympathetic ganglion was infected by the vesicular-zoster virus, with the performance of cluster headache. Case presentation: The patient underwent headache on left side orbit, supraorbital and temporal regions after infection of herpes zoster for 8 months, with lacrimation, conjunctival injection and nasal discharge. Pulsed radiofrequency of the SPG under ultrasound guidance was performed, we applied 2 cycles of PRF at 42℃for 120 seconds each time. Partial response lasted 1 month and the pain had recover to its baseline level. Low-temperature plasma radiofrequency ablation (coblation) technology is a relatively new technology that has shown promise in treating neuropathic pain. Then a CT-guided coblation of SPG was performed, used three of intensity for coblation (lasting for 30s, repeat twice) and six of intensity for coagulation (lasting for 30s, once). After coblation, the patient reported completed pain relief and autonomic symptoms disappeared without any side effects. The patient was satisfied with the effect on post-operative telephone follow-up performed on day 7, month 1 and month 3, pain VAS score remained on 0/10. Conclusions: Our report demonstrates that coblation technology is succeseful treatment for cluster headache in this case, but this finding still needs additional studies for confirmation.

Abstract Objectives: Endoscopic nasopharyngectomy (ENPG) with en bloc resection has been well accepted in resectable locally recurrent nasopharyngeal carcinoma (rNPC), but it is difficult to master the technique and disseminate. We designed a novel method using low-temperature plasma radiofrequency ablation (LPRA) with piece resection and evaluated the survival benefit.Materials and Methods: A total of 56 resectable rNPC patients were retrospectively analyzed, and the following factors were assessed: ratio of R0 margin, overall survival rate (OS), local relapse-free survival rate (LRFS), and progression-free survival rate (PFS).Results: All surgeries were successfully performed without any severe postoperative complications or deaths. The median operation time was 130 minutes (range, 32–280 minutes), with little blood loss (median, 30 ml; range, 5–500 ml). The average number of hospital days postoperation was 3 days (range, 2–5 days). All cases (100.0%) had R0 margins. The nasopharyngeal defects were completely re-epithelialized in 53 (94.6%) patients. The 2-year OS, LRFS, and PFS rates of the entire cohort were 100%, 90.7% and 88.6%, respectively. Multivariate Cox proportional hazards model analysis indicated that cycles of radiotherapy were independent risk factors for LRFS (hazard ratio [HR], 16.607; 95% CI 1.638–168.417; P = 0.017) and PFS (HR, 7.424; 95% CI 1.190–46.320; P = 0.032).Conclusions: Radical endoscopic nasopharyngectomy is a novel, safe and relatively easier method for treating resectable rNPC by using low-temperature plasma radiofrequency ablation with piece resection. However, further data and longer follow-up time are needed to prove its efficacy.

Background. Very few studies have been conducted to compare carbon dioxide laser microsurgery (CO2-LS) with low-temperature plasma radiofrequency ablation (LTP-RFA) in treating T1a glottic cancer. Therefore, we conducted this study to compare the efficacy of CO2-LS and LTP-RFA to define a superior therapeutic modality for T1a glottic cancer.Methods. Patients (n=131) with T1a glottic cancer were recruited between January 2010 and September 2014. The included patients were randomly assigned to either receive CO2-LS (n=65) or LTP-RFA (n=66). We conducted the following multidimensional vocal assessments: (i) videostroboscopic evaluation; (ii) auditory-perceptual evaluation; (iii) aerodynamics/ efficiency; (iv) acoustics; and (v) self-assessment questionnaires. Meanwhile, the surgery time and three-year overall survival rates in two groups were recorded. The predefined primary endpoint was overall survival, and the minimum follow-up time was set to six months.Results. After treatment, we found that the structure and vibration of vocal cord might recover more quickly in patients receiving LTP-RFA than in patients receiving CO2-LS, and moreover, the patients in the LTP-RFA group had the better vocal functions. Meanwhile, the surgery time was significantly less in the LTP-RFA group (8.83±1.59 minutes) than in the CO2-LS group (12.49±1.40 minutes) (p<0.00001). In addition, the two intervention methods had the similar three-year overall survival rates (94% versus 96%, p=0.58).Conclusion. These results indicated that both LTP-RFA and CO2-LS could effectively treat T1a glottic cancer, and LTP-RFA might have some advantages in voice function. Limited by the relatively small sample size, future studies were needed to validate our conclusion.
