Application of autogenous bone pate for atticus reconstruction and mastoid cavity obliteration in tympanoplasty with mastoidectomy / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To observe the curative effect of autogenous bone pate for atticus reconstitution and mastoid cavity obliteration in canal wall down mastoidectomy with tympanoplasty.@*METHOD@#The 60 patients (60 ears) of cholesteatomatous tympanitis were randomly divided into 2 groups. The experimental group underwent canal wall down mastoidectomy with tympanoplasty and using autogenous bone pate for atticus reconstitution and mastoid cavity obliteration. The control group only underwent canal wall down mastoidectomy with tympanoplasty. All patients were followed up for 0.5-2 years. Improvement of hearing and dry ear time in these two groups was retrospectively observed.@*RESULTS@#There are significant difference between two groups in improvement of hearing and dry ear time, according to follow-up and analysis of therapeutic efficacy (P < 0.05).@*CONCLUSION@#Hearing can be improved, dry ear time can be shorten and correlative complication can be decreased by atticus reconstruction and mastoid cavity obliteration with autogenous bone pate in canal wall down mastoidectomy with tympanoplasty, which guarantees the normal activity space of auditory bone chain.
