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 (Pgt;0.01). 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 (Plt;0.001). Conclusion Dressing change under the otoendoscope after mastoidectomy may not improve the ear drying rate but can shorten the ear drying time.
目的探討納吸棉在慢性中耳炎術(shù)后填塞中的效果，為臨床耳科手術(shù)填塞物的選擇提供依據(jù)。 方法將 2012年 4月－2013年 1月住院接受同一醫(yī)療組醫(yī)生手術(shù)治療的 200 例慢性中耳炎患者，根據(jù)入院時間分為對照組和試驗組，對照組采用碘仿紗條材料填塞術(shù)耳腔，試驗組采用納吸棉材料填塞術(shù)耳腔，觀察兩組患者術(shù)后 48 h內(nèi)術(shù)耳疼痛、滲血量，首次抽取填塞物時術(shù)腔出血及疼痛情況。 結(jié)果試驗組患者術(shù)后 48 h 內(nèi)術(shù)耳疼痛、首次抽取填塞物時的疼痛及出血情況均低于對照組，兩組比較差異均有統(tǒng)計學(xué)意義（P＜0.05）；兩組患者術(shù)后 48 h內(nèi)術(shù)耳滲血情況差異無統(tǒng)計學(xué)意義（P＞0.05）。 結(jié)論慢性中耳炎術(shù)后應(yīng)用納吸棉填塞術(shù)腔能提高患者舒適度，減少抽取填塞物時對術(shù)耳的損傷，促進(jìn)術(shù)耳康復(fù)。
