Abstract
Background We explored a new method for measuring the length of artificial stapes during stapedotomy in otoendoscopic middle-ear surgery using a flexible ruler. Material/Methods A retrospective analysis was conducted on 56 cases of otosclerosis, comprising 56 ears with a follow-up of over 6 months and complete data. Patients were admitted to the Department of Otology, Huazhong University of Science and Technology Union Shenzhen Hospital from July 2020 to June 2022. SPSS statistical software was used for efficacy analysis. The results of different measurement methods on the implantation time of the prosthesis and postoperative hearing follow-up were compared. Results The 56 patients were randomly divided into 2 groups. In 1 case measured by the metal measuring stick, the prosthesis was too short and was replaced during the operation; 2 patients experienced transient dizziness postoperatively, and the other patients had no surgical complications. All 56 patients had varying degrees of hearing improvement after surgery, and no dislocation of the ossicular chain was observed during the follow-up. There was a statistically significant difference in the implantation time of the prosthesis between the different measurement methods ( P <0.05). The improvement in hearing in the flexible ruler group was statistically significant ( P <0.05). Conclusions The selection of the length of the ossicular prosthesis is a crucial step in the operation and can directly affect hearing outcomes. The use of a flexible ruler to measure prosthesis length can significantly shorten operation time and improve hearing, and the ruler is easily obtainable. It is worth promoting its application in ear endoscopic stapedotomy.
