A retrospective research method was used to analyze the characteristics of ossiculoplasty surgery between oto-endoscope and microscope to explore the efficacy and advantages of ossiculoplasty surgery under oto-endoscope, and to provide a reference for its clinical application.

This study recruited 62 patients with conduction hearing loss who had undergone simple ossiculoplasty surgery in the five hospitals in China (45 cases under oto-endoscope operation and 17 cases under microscope operation). The operation procedures, surgery time, postoperative complications and hearing improvements were compared between the two groups.

The average time of surgery in the oto-endoscope group and microscope group was 43.56±18.25 min and 48.25±8.35 min, respectively. The significant difference of operation time did not be detected between the two groups (F=3.26, P>0.05). There were no significant differences in the incidences of postoperative complications between the two groups (tinnitus: c2=0.14, P>0.05; dysgeusia: c2=0.04, P>0.05; vertigo: c2=0.06, P>0.05). The averages of air-bone gap between the two groups were no significant differences before surgery (F=4.31,P>0.05), as well as at the third month after operation (F=3.89,P>0.05). The air-bone gap values of the third month post surgery were significantly lower than that before operation in the two groups (oto-endoscope group: t=2.31, P<0.05; microscope group: t=2.26, P<0.05).The ossiculoplasty surgery did not have significant differences in the operation time, postoperative efficacy, and occurrence of complications between the oto-endoscope and microscope. The advantages of oto-endoscope surgery are the clear vision, detailed observation, less trauma, and faster postoperative recovery. Therefore, oto-endoscopic ossiculoplasty surgery is deserved for better clinical application.
