Long-term Efficacy Study Of Microvascular Decompression For Trigeminal Neuralgia

Objective: This reaserch aimed to study the long-term effects of microvascular decompression(MVD)for primary trigeminal neuralgia。Material/Methods: We retrospectively analyzed the clinical data of 787 patients with primary trigeminal neuralgia in our hospital from January 2006 to January 2013.We observe the rate of disappearance of postoperative pain in all patients,the recurrence rate of pain within 5 years after surgery and after 5 years,and the delay in cure rate,and observe and record postoperative complications.All patients underwent MVD treatment under the same doctor,telephone,letter or outpatient follow-up.Results: In all 785 postoperative visits,including 725 cases that meet the criteria.Postoperative time was 5 to 12 years.Postoperative pain disappeared in 659 cases.The rate of pain disappeared immediately after surgery was 90.89%,and the pain-free rate in 5 years was 88.14%.66 cases were relieved or ineffective after operation,and 20 cases showed delayed healing.At the time of discharge,patients who had pain disappeared during the follow-up period.There were 48 recurrences,of which 40 recurred within 5 years and 8 recurred after more than 5 years.The total recurrence rate was 7.07%.and 2 cases of death.Other complications include decreased facial sensation,peripheral facial paralysis,tinnitus and hearing loss,headache,dizziness,and sleep disturbances.Conclusions: MVD is an effective surgical method for the treatment of trigeminal neuralgia,and its long-term efficacy is very well.The painless rate of typical trigeminal neuralgia is higher than atypical trigeminal neuralgia.
