Objective To evaluate the efficacy of resection for pituitary tumors through transsphenoidal approach with endoscopic neuronavigation assisted. Methods From October 2014 to April 2018, 10 patients with pituitary tumor were operated in our hospital with neuronavigation, which were set as the observation group. Meanwhile, 10 patients with pituitary tumor underwent surgical treating through transsphenoidal approach without neuronavigation were set as the control group. SPSS 19.0 were used for statistical analysis to compare the difference between the two groups, including the operation time, blood loss, hospitalization time, hormone level, clinical total efficiency, and complications in the two groups. Results The operation time, blood loss and hospitalization time of the observation group were less than that of the control group, and there was statistical significance (P<0.05). The efficiency rate and overall efficiency rate of the observation group were a little more than that of the control group, but there was no statistical significance (P＞0.05). The level of growth hormone (GH) and prolactin (PRL) of the observation group were less than that of the control group, and there was statistical significance (P<0.05). And there was no statistical significance between the incidence rate of postoperative complications of the two groups. Conclusion The efficacy of resection for pituitary tumors through transsphenoidal approach with endoscopic neuronavigation is significant, which may shorten the course, reduce the blood loss, quicken recovery of a patient from operation, and improve the hormone level. It is worthy to be recommended to clinical application.
