Timing of Tympanoplasty in Treatment of Chronic Otitis Suppurative Media

Objective To explore the timing of tympanoplasty in treatment of chronic otitis suppurative media,in order to provide basis for the clinical treatment.Methods A retrospective analysis of 50 cases(56 ears)with hronic otitis suppurative media in our hospital Jun.2009 to Jun.2011 were divided into 7 groups according to the time of dry ear,and 8 ears were selected in each group to conduct tympanoplasty,the hearing level of each patient was recorded and follow-up was done for 3 months to analyze the correlation between hearing level and operation dry ear time.Results The highest hearing improvement after tympanoplasty as treatment of chronic otitis suppurative media was after 2-4 months for dry ear by the fitting equation:Y^=12.5567+0.19671x-0.03221x2.Conclusion The optimal time of tympanoplasty as treatment of chronic otitis suppurative media was after 2-4 months for dry ear,which can increase the successful rate and maximize the hearing threshholds,thus improve patients life quality.
