CT-guided low temperature plasma coblation of sphenopalatine ganglion for treating sphenopalatine neuralgia / 中国介入影像与治疗学

ABSTRACT

Objective To evaluate the efficacy and safety of CT-guided low temperature plasma coblation of sphenopalatine ganglion for treating sphenopalatine neuralgia. Methods: Totally 37 patients with sphenopalatine neuralgia underwent CT-guided low temperature plasma coblation of sphenopalatine ganglion. Visual analogue scale (VAS) and numerical rating scale (NRS) were obtained at 24 hours, 7 days, 1 month, 3 months and 6 months after operation. The efficacy and postoperative incidence of facial numbness were evaluated and calculated,and the postoperative adverse reactions were recorded. Results: VAS scores significantly decreased 24 hours, 7 days, 1 month, 3 months and 6 months after operation (all P<0.01). The effective rate of coblation 24 hours, 7 days, 1 month, 3 months and 6 months after operation was 89.19% (33/37), 97.30% (36/37), 100% (37/37), 100% (37/37) and 100% (37/37), respectively, and the incidence of facial numbness was 67.57% (25/37), 54.05% (20/37), 29.73% (11/37), 8.11% (3/37) and 5.41% (2/37), respectively. No severe numbness was observed. Facial hematoma and postural hypotension were noticed in 18 (18/37, 48.65%) and 3 (3/37, 8.11%) patients 24 hours after operation, respectively. All the symptoms remitted completely within 72 hours after expectant treatment. No other adverse reaction was found. Conclusion: CT-guided low temperature plasma coblation is effective and safe for treating sphenopalatine neuralgia.
