Percutaneous Microballoon Compression Of The Gasserian Ganglion For The Treatment Of Primary Trigeminal Neuralgia

Objective:In this article,62 patients with primary trigeminal neuralgia undergoing PMC surgery in our hospital were followed up,and a recollection analysis was conducted to summarize the influencing factors of PMC surgery success and postoperative complications,and analyze the concurrency,so as to provides a basis for future surgical treatment and prevention of postoperative complications.Methods:We reviewed 62 cases of trigeminal neuralgia treated with PMC in our hospital from February 2019 to March 2020.The clinical data of these 62 patients were followed up,and the gender,age,course of disease,and operation factors were analyzed to summarize its impact on the success of surgery and postoperative complications.Results:Among the 62 patients selected in this group,61(98.4%)had immediate relief of pain after PMC,and 1(1.6%)had no pain relief.The results of these cases which the prognosis of pains is graded according to BNI were sorted: 54 cases of grade Ⅰ(87.1%),2 cases of grade Ⅱ(3.2%),2 cases of grade Ⅲ(3.2),0 cases of grade Ⅳ,and 4 cases of grade V(6.5%).59 patients had ipsilateral face paresthesia after operation,accounting for 95.2%;60 patients with ipsilateral masticatory muscle weakness(symptoms were relieved or well tolerated within 3 months),accounting for 96.8%;5 patients with herpes(postoperative recovery in about 1 week),accounting for 8.1%;3 cases of abductor nerve palsy(2 cases recovered to normal within 1 week after operation,and another improved after 3 months),accounting for 4.8%.There were 59 cases of the OCR during operation,accounting for93.7%.The patients in this group were hospitalized for an average of 3.5 days.Hearing and vision loss were not be found.No intracranial hematoma was found,and no deathsoccurred.Age and balloon compression time were statistically significant for the postoperative pain relief rate(P <0.05).There was no statistical difference in the course of trigeminal neuralgia,pain branches,balloon size,and balloon shape(P> 0.05).Conclusion:1.For patients with primary trigeminal neuralgia,the effect of PMC surgery is obvious,and patients about 98.4% are restored to health.2.The OCR during PMC surgery can be used as one of the indicators for the needle to enter the foramen ovale.3.Most of the postoperative complications of PMC are minor and can be recovered or tolerated within a certain period of time.4.The balloon compression time less than 2 minutes which can easily lead to the recurrence of trigeminal neuralgia.Choosing an appropriate balloon compression time can help reduce the pain recurrence after PMC.5.In terms of age,the prognosis of PMC surgery is better and the recurrence rate is lower in those younger than65 years old.6.In this group of cases,factors such as the course of trigeminal neuralgia,pain branch,size and shape of the balloon were not be found to have any effect on the recurrence of pain and complications after PMC.
