Abstract：Objective To report efficacy of low temperature plasma technology in otoscopic myringoplasty.Methods Patients with chronic suppurative otitis media undergoing otoscopic myringoplasty from July 2021 to Febru-ary 2022(n=60)were randomly divided into a study group and a control group(30 in each group).A plasma knife was used for incision in the ear canal in the study group,while the regular scalpel was used for incision in the control group.Intra-and post-operative differences between the two groups were compared.Results Surgical time was shorter in the study group than in the control group(P<0.05),with no significant difference in the length of hospital stay,postopera-tive healing time,external ear canal stenosis,or incidence of adverse reactions.There was no significant difference in pre-and post-operative air conduction thresholds or air-bone gaps between the two groups,although post-operative air conduction threshold and air-bone gaps in the both groups showed significant improvement(P<0.05).Conclusion Low temperature plasma technology provides excellent bleeding control and a clear surgical field that helps shorten the opera-tion time during otoscopic myringoplasty,which is suitable for adoption in practice.
