Objective: To explore the therapeutic effect of drug stent-assisted endoscopic tympanoplasty type I in the treatment of chronic suppurative otitis media. Methods: From October 2022 to January 2024, 124 patients with simple chronic suppurative otitis media admitted to our hospital were collected and randomly divided into experimental group [64 cases(64 ears)]and control group [60 cases(60 ears)]. The experimental group received drug stent-assisted endoscopic tympanoplasty type I, while the control group received traditional endoscopic tympanoplasty type I. The bleeding volume, surgical time, hospital stay, dry ear time, therapeutic effect, postoperative adverse reactions, preoperative and postoperative hearing, pain visual analog scale(VAS), cross-sectional area of the affected ear canal, generic quality of life inventory-74(GQOL-74) of the 2 groups were documented. Results: Compared with the control group, the surgical time of the experimental group was significantly increased(P<0.05). There was no statistically significant difference in bleeding volume and hospital stay between the 2 groups(P>0.05). Before surgery, the airway hearing threshold, air bone conduction difference, bone conduction hearing threshold, VAS, cross-sectional area of the affected ear canal and quality of life score had no differences between the 2 groups(P>0.05). At 2 and 4 weeks after surgery, the airway hearing threshold, air bone conduction difference, bone conduction hearing threshold, and VAS of the 2 groups were all reduced(P<0.05). Compared with the control group, bone conduction hearing threshold, the airway hearing threshold, air bone conduction difference, and VAS of the experimental group were significantly reduced(P<0.05). Compared with the control group, the cross-sectional area of the affected ear canal and quality of life score of the experimental group was significantly increased at 3 months after surgery, and the dry ear time was significantly reduced(P<0.05). Compared with the control group, the total effective rate of the experimenal group was significantly increased(P<0.05). 1 patient in each group had mild infection after surgery, and the rest of the patients had mild infection. Conclusion: Drug stent-assisted endoscopic tympanoplasty type I can be used to treat chronic suppurative otitis media, which can significantly shorten ear drying time, alleviate pain, improve hearing, increase cross-sectional area of the affected ear canal and improve quality of life. |
