Application of the follower arm endoscope holder in type i tympanoplasty
Objective:To investigate the surgical outcomes and safety of the follower arm endoscope holder in assis-ting type Ⅰ tympanoplasty.Methods:The clinical data of 16 patients who underwent type Ⅰ tympanoplasty at the Depart-ment of Otorhinolaryngology.Peking Union Medical College Hospital,from November 2022 to September 2023 were retrospectively analyzed,among which 8 cases were operated by traditional otoscopy and 8 cases were operated by suppor-ted endoscopy.The surgical procedure was analyzed and the completion of supported endoscopic operation was observed,while the duration of the operation,the time consumed by the main steps,the frequency of wiping the lenses,the periop-erative complications,and the improvement of the postoperative hearing were recorded and statistically analyzed.Results:Supporting endoscopic technology achieved real-time suction of bleeding,simultaneous traction and separation of tissues,precise removal of calcified spots on the inner side of the eardrum,trimming of the external auditory canal flap,stable separation of the handle of the malleus and the eardrum,and tensioned repositioning of the skin-cartilage flap.The aver-age duration of surgery,time for external auditory canal flap preparation,and time for repositioning the skin-cartilage flap were reduced in the supporting endoscopic surgery group compared to the control group.The average lens wiping frequen-cy was significantly lower in the supporting endoscopic surgery group compared to the control group.There was no statis-tically significant difference in postoperative hearing improvement between the two groups,and no infections or the need for secondary surgery due to eardrum re-perforation occurred postoperatively.Conclusion:Supported endoscopy technolo-gy realizes the need for endoscopic two-handed operation and convenient switching between one and two hands,accompli-shes many operations that cannot be done by traditional endoscopic surgery,solves the problems of previous intraoperative one-handed operation and image instability,shortens the average operation time compared with traditional otoscopic sur-gery,and decreases the frequency of intraoperative wiping of the lens significantly compared with traditional otoscopic surgery,which is potentially worthwhile in terms of shortening the learning curve.
