| Objective: To compare the efficacy between otoscope and microscope tympanoplasty type I in the treatment of chronic suppurative otitis media, and to analyze the influencing factors of short-term postoperative hearing recovery. Methods: 158 patients with chronic suppurative otitis media who were admitted to our hospital from March 2019 to February 2022 were selected, all of whom were treated with tympanoplasty type I. According to different surgical methods, they were divided into otoscopy group (81 cases) and microscope group (77 cases), and the clinical efficacy and incidence of poor hearing recovery 6 months after operation were compared between the two groups. The related data were collected, and the influencing factors of short-term postoperative hearing recovery were analyzed by multivariate Logistic regression. Results: There was no statistical difference in the number of tympanic membrane perforation between the two groups (P>0.05). The operation time and hospital stay in otoscope group were shorter than those in microscope group, and the intraoperative blood loss, hospitalization expenses, cases with dry ear time >1 month and cases with auricle numbness were less than those in microscope group (P<0.05). There was no significant difference in the incidence of poor hearing recovery 6 months after operation between the otoscopy group and the microscope group (P>0.05). The results of univariate analysis showed that the hearing recovery effect 6 months after operation in patients with chronic suppurative otitis media was related to the tympanic mucosa, tendo musculi tensoris tympani, eustache tube condition, whether tympanic sclerosis, listen to whether the ossicle surrounded by granulation and whether purulent secretion in tympanic chamber before operation (P<0.05). Multivariate Logistic regression analysis showed that tendo musculi tensoris tympani defect, eustache tube impassability, tympanic sclerosis, listen to with the ossicle surrounded by granulation and purulent secretion in tympanic chamber before operation were the risk factors for poor hearing recovery in the short term after chronic suppurative otitis media (P<0.05). Conclusion: Compared with microscope tympanoplasty type I in the treatment of chronic suppurative otitis media, otoscope surgery can shorten the operation time, hospital stay, reduce the amount of intraoperative bleeding and hospitalization expenses, and reduce the incidence of complications. In addition, the short-term postoperative hearing recovery effect of patients is affected by many factors, such as tendo musculi tensoris tympani, eustache tube, tympanic sclerosis, listen to with the ossicle surrounded by granulation, purulent secretion in tympanic chamber before operation and so on. |
