Value of titanium artificial ossicular chain implantation in reducing hearing threshold and improving hearing status in patients with chronic suppurative otitis media undergoing tympanoplasty
[Objective]To investigate the effect of titanium artificial ossicular chain implantation in tympanoplasty on reducing hearing threshold and improving hearing status in patients with chronic suppurative otitis media.[Methods]Eighty patients with chronic suprurative otitis media treated in the Department of Otorhinolaryngology of the Second Affiliated Hospital of Henan University of Science and Technology from January 2019 to January 2022 were selected as research objects,and randomly divided into control group(40 cases)and implantation group(40 cases)by the method of number table.The control group received simple tympanoplasty and autologous osculus chain reconstruction without titanium artificial ossicular chain implantation.Patients in the implantation group were implanted with titanium artificial ossicular chain during tympanoplasty.The threshold values of bone conduction and air conduction hearing,air conduction difference,improvement effect of hearing status,complications and recurrence rate were compared between the two groups before and after surgery.[Results]The effective rate of hearing improvement in implant group was higher than that in control group(P<0.05).The hearing threshold after surgery was lower than that before surgery,and the air-conduction hearing threshold and air-bone conduction difference in the implantation group were lower than those in the control group(P<0.05),but there was no statistical significance in bone-conduction hearing threshold between the groups(P>0.05).There was no significant difference in the incidence and recurrence of postoperative complications between the two groups(P>0.05).[Conclusion]Implantation of titanium artificial ossicular chain during tympanoplasty can effectively improve the hearing level of patients with chronic suppurative otitis media,reduce the threshold of air conduction hearing and air bone conduction,and does not increase the risk of postoperative complications and disease recurrence.The effect is accurate,worthy of clinical application and further research.
