Application of the cortical bone packing in external auditory bony canal and attic reconstruction in tympanoplasty with mastoid obliteration
摘要
Abstract
OBJECTIVE To explore the application value of the cortical bone packing in external auditory bony canal and attic reconstruction in tympanoplasty.METHODS A total of 30 patients admitted during the period of middle ear cholesteatoma patients in our hospital from March 2014 to March 2016,were randomly divided to observation group and control group,the radical mastoidectomy with canal wall down was adopted in the control group,the radical mastoidectomy with canal wall down combined with bone autograft in the external auditory meatus and bony powder mastoid obliteration in observation group,the postoperative out-come between two groups were compared.RESULTS There was no significant difference between the speech frequency average air bone conduction and air conduction threshold before the treatment in two groups.There was significant difference between the speech frequency average air bone conduction and air conduction threshold after the treatment(P＜0.05),the air conduction threshold significantly reduced,the patients in the observation group were significantly lower than the control group,there was no recurrence of cholesteatoma in two groups of patients before and after the treatment during follow-up period;the dry ear time in observation group was significantly lower than that of the control group,and dry ear the incidence was significantly higher than that of the control group,the difference is statistically significant(t=2.758,4.865,P＜0.05).CONCLUSION Radical mastoidectomy with canal wall down combined with the cortical bone packing in external auditory bony canal and attic reconstruction,can effectively presesre the patient hearing,it should be recommended.关键词
