Application of Otoendoscope after Mastoidectomy

Objective To evaluate the application of otoendoscope in dressing change after mastoidectomy.Method Between March 2003 and October 2008,89 patients（89 ears） underwent mastoidectomy in Department of Otolaryngology Head and Neck Surgery,West China Hospital of Sichuan University and in Department of Otolaryngology,Nuclear Industry 416 Hospital of Chengdu.The patients were randomly divided into two groups by simple randomization（trial group and control group）.Forty-five patients in the trial group underwent the dressing change under otoendoscope,while 44 patients in the control group under the routine method.The ear drying rate and the ear drying time in the two groups were observed.Results The ear drying rate was 93.3%（42 dry ears）in the trial group,and was 90.9%（40 dry ears） in the control group;the difference between the two groups was not significant（P0.01）.The ear drying time was（50.8±13.4） days in the trial group and was（60.7±12.2） days in the control groups;the difference between the two groups was significant（P0.001）.Conclusion Dressing change under the otoendoscope after mastoidectomy may not improve the ear drying rate but can shorten the ear drying time.
