特定电磁波在中耳乳突术后的应用

Application of electromagnetic waves to post-operative of otitis media and mastoiditis patients

目的探讨中耳乳突术后特定电磁波治疗器(special electromagnetic therapeutic apparatus,TDP)局部照射治疗对干耳、移植膜的成活率及预防外耳道真菌感染的影响。方法采用特定电磁波对68例(68耳)中耳乳突术后局部照射作为治疗组,选择66例(66耳)中耳乳突术后按常规治疗作对照组,比较两组疗效。结果治疗组68例抽纱条后15 d内全部干耳,6个月后复查无发生外耳道真菌感染,36例移植膜全部成活;而对照组66例抽纱条后,≤15 d干耳12例,占18.18%(P<0.05),发生外耳道真菌感染8例,占14.8%(P<0.05);32例移植膜成活24例,占75%(P<0.025)。结论中耳乳突术后采用特定电磁波局部照射治疗对提高干耳率及移植物的成活率,缩短干耳时间,防止外耳道真菌感染,具有积极的临床意义。

Objective To study the effect of special electromagnetic therapeutic apparatus （TDP） therapy on the dried ear rate, survival rate of transplanted fascia, and prevention of fungal infection in the patients with otitis media and mastoiditis after opera- tions. Methods Sixty -eight cases （ears） treated with special electromagnetic waves （trial group） were compared with the 66 cases with routine treatment （control group）. Results All the 68 cases in trial group achieved dried ears in 15 days after removing the dressing in the external canals, and none of which were found fungal infection in 6 months＇ follow - up. The survival rate of transplan- ted fascia in 36 cases of treatment group was 100%. The response rates in the control groups were 18.18% （P 〈 0.05 ）, 14.8% （P 〈 0.05 ）, and 75% （P 〈 0. 025 ）, respectively. Conclusions The special electromagnetic waves treatment is helpful in raising the rate of dried ear and surviving transplanted fascia, and is excellent in shortening drying ear time and preventing fungal infection in external canals.
