OBJECTIVE: To explore and analyze the clinical efficacy of a stepwise decompression technique in the treatment of trigeminal neuralgia (TN) caused by vertebrobasilar dolichoectasia (VBD).
METHODS: A total of 918 patients with TN admitted to our hospital from June 2015 to May 2020 were divided into the VBD group (n = 61) and the conventional group (n = 857). The VBD group underwent stepwise decompression, while the conventional group received traditional microvascular decompression (MVD) surgery. Patients associated with the VBD were divided into direct compression (n = 14) and indirect compression group (n = 47) who had compression by other vessels in the presence of the VBD. Thereafter, the clinical data, intraoperative findings, efficacy, and complications were analyzed.
RESULTS: The curative ratio, efficacy, and recurrence rate for the VBD and conventional group were 83.6% and 89.6%, 93.4% and 95.3%, and 8.2% and 5.3%, respectively. The curative ratio, efficacy, and recurrence rate for the direct compression and indirect compression group were 85.7% and 83.0%, 92.9% and 93.6%, and 7.1% and 8.5%, separately. There were no significant differences in the curative ratio, efficacy, recurrence rate, and the incidence of complications between the two series (P > 0.05).
CONCLUSION: For TN caused by VBD, stepwise decompression not only reduces the direct compression of the trigeminal nerve by VBA but also allows identification and decompression of the actual vessels responsible for the compression. It has a good curative ratio, efficacy, and long-term pain relief rate, and it does not significantly increase the incidences of complications after surgery.
