Objective To investigate the application of ear endoscopic in artificial stapes surgery of otosclerosis.Methods Artificial stapes surgery was performed by two amplification device, microscope or ear endoscope, in 64 cases of patients with otosclerosi. Then compare the operation time and analyze the effect of surgery.Results Patients postoperative hearing of the two groups were signiifcantly improved, the difference of air bone conduction was statistically signiifcant (P < 0.05). There has no postoperative complications of all the patients. While the operation time was slightly longer in ear endoscope group than that in microscope group, and the difference has statistical significance (P > 0.05).Conclusion Compared with microscopic surgery, ear endoscope artificial stapes surgery has its’ unique advantages with clear image and small trauma.
