Abstract:
Objective To compare the efficacy of CT-guided radiofrequency thermocoagulation (RFTC) treatment through the inside and outside of the foramen rotundum for primary trigeminal maxillary neuralgia.Methods Forty-eight patients of both sexes,aged 58-75 yr,suffering from primary trigeminal neuralgia the 2nd trigeminal branch pain,scheduled for elective CT-guided trigeminal RFTC,were divided into 2 groups (n =24 each) using a random number table:inside of foramen rotundum group and outside of foramen rotundum group.The needle was inserted until the lateral 1/3 of the foramen rotundum was reached under CT guidance in inside of foramen rotundum group or until the outside of the foramen rotundum was reached in outside of foramen rotundum group.High-temperature RFTC 95 ℃ was performed for 120 s,repeating for 2-3 cycles.The current sensory threshold at different frequencies was measured at 1 day before and after operation.Numeric rating scale score was performed at 1 day,30 days,1 yr and 2 yr after operation,effective RFTC treatment was defined as numeric rating scale score≤ 1,and the condition of postoperative effective RFTC treatment was recorded.The development of adverse reactions such as facial hematoma,corneal ulcer,injuring the other branch and cerebrovascular accidents was recorded.Results Compared with outside of foramen rotundum group,the current sensory threshold on the affected side at frequency of 2 000 Hz was significantly increased at 1 day after operation,the rate of effective RFTC treatment was increased 2 yr after operation (P＜0.05),and no significant change was found in the incidence of postoperative facial hematoma in inside of foramen rotundum group (P＞0.05).Conclusion The long-term curative effect of CT-guided RFTC treatment for primary trigeminal maxillary neuralgia through the inside of the foramen rotundum is better than that through the outside of foramen rotundum.
