Abstract：Objective To discuss the technique of whole-range encircling method of microvascular decompression (MVD) for primary trigeminal neuralgia (PTN) and its effect. Methods The clinical data of 126 patients with PTN treated by microvascular decompression were analyzed retrospectively. Of 126 patients with PTN, 69 (observed group) were treated by MVD whole-range encircling method and 57 (control group) by conventional MVD. The treatment effects and rates of complications occurrence and PTN recurrence were compared between the two groups. All patients were followed from 6 months to 2 years. Results The blood vessels responsible for PTN were found in 115 patients, and 11 not. The effective rate (98.55％) was significantly higher in the observed group than that (92.98％) in the control group (P<0.05). PTN recurrence rate (3.45％) was significantly lower in the observed group than that (17.50％) in the control group (P<0.05). There was no significant difference in the rates of complications occurrence between both the group (P>0.05). Conclusions The whole-range encircling method of MVD is a safe and effective method to treat PTN, because it can fully decompress trigeminal never, prevent the decompression material from sliding and reduce PTN recurrence rate without increasing complications.
