OBJECTIVE To explore the efficacy of otoscope assisted dissection myringoplasty.METHODS Fifty-nine patients with otitis media suppurative admitted from January 2019 to August 2022 were underwent otoscope assisted dissection myringoplasty.Tympanic membrane healing,hearing improvement,and complications were observed.RESULTS The total perforation healing rate was 98.3%(58/59).One case had obtuse angle healing at the anterior lower part of the tympanic membrane,and one case had local cholesteatoma beads on the tympanic membrane.The preoperative average speech frequency air conduction hearing threshold was(40.2±7.9)dB HL,and postoperative one year was(22.5±8.3)dB HL,with statistically significant differences(t=11.31,P<0.01);The preoperative average speech frequency and bone conduction was(26.3±6.1)dB HL,and postoperative one year was(12.8±5.7)dB HL,with statistically significant differences(t=9.54,P<0.01).CONCLUTION The mezzanine tympanoplasty under otoscopy owning the advantages of both otoscopy and mezzanine methods,have the outcomes of minimal damage,high healing rate,and postoperative hearing improvement.It is an ideal tympanoplasty for repairing perforation of tympanic membrane.
