Abstract:
Objective To study the therapeutic effect of CT-guided puncture for accurate radiofrequency thermocoagulation through the pteroygopalatine fossa approach in the treatment of maxillary neuralgia. Methods From May 2005 to March 2011, 18 patients with maxillary neuralgia underwent CT-guided puncture through the pteroygopalatine fossa approach for accurate radiofrequency thermocoagulation. Axial CT scanning parallel to the middle cranial fossa base was conducted for the patients to define that the puncture needle was within the pteroygopalatine fossa before radiofrequency thermocoagulation being performed at 85℃ for 60 seconds. The thermocoagulation was repeated once until anesthesia covered the innervation area of the superior alveolar nerve. Results Follow-up,ranging from 6 to 22 months (mean,10 months),showed successful puncture in all patients.According to the Heft-Parker' visual analog scale, 15 cases (83.3%) were rated as excellent and 2 as good (11.1%).There were no intraoperative or postoperative major complications in the patients. Conclusions Since CT-guided puncture through the pteroygopalatine fossa approach can safely ensure accurate radiofrequency thermocoagulation for treatment of maxillary neuralgia, it has a high therapeutic efficacy for the patients.It is also a minimally invasive procedure that can be easily and safely performed in clinic.
