Abstract： Objective:To investigate the effect of nasal endoscopic salvage surgery optic nerve injury caused by bone fiber benign tumor of nasal cavity and paranasal sinuses.Methods:10 patients with optic nerve lesion caused by benign bone fiber tumor of nasal cavity and paranasal sinuses were randomly divided into observation group and control group, with 5 cases in each. The control group received open salvage surgery, the observation group received nasal endoscopic salvage surgery. The improvement of vision, the incidence of complications and the recurrence rate were compared between the two groups.Results:The total effective rate of vision improvement in the observation group was 100%, higher than that in the control group 60%, the postoperative visual field of the observation group was higher than that of the control group, the incidence of complications was 20% The recurrence rate was 0%in observation group, while the datawas 80% and 20% in control group.Conclusions:The endoscopic salvage surgery can effectively improve visual acuity, reduce the incidence of complications and disease recurrence.
