缩短开放式乳突根治术后干耳时间的探讨

Application of operation skills in decreasing dry ear time after modified radical mastoidectomy

目的探讨缩短慢性化脓性中耳炎改良乳突根治术后干耳时间。方法我科于2006年7月-2008年6月对52例(耳)慢性化脓性中耳炎行改良乳突根治术,其中A组常规方法治疗慢性化脓性中耳炎20例,B组改进方法后治疗慢性化脓性中耳炎32例(均作耳甲腔成型及乳突腔回填),比较两组干耳时间。结果A组20例患者干耳时间96.25±39.33d,B组32例患者干耳时间明显缩短为59.28±14.77d,两组相比有统计学差异(P<0.01)。结论术中耳甲腔成型、乳突术腔充填、病变彻底清除是缩短乳突手术后干耳时间的关键。

Objective To study how to decrease the dry ear time after modified radical mastoidectomy for chronic suppurative otitis media. Methods Of the 52 patients with chronic suppurative otitis media who underwent modified radical mastoidectomy at our department during July 2006-June 2008, 20 in group A received routine therapy and 32 in group B received modified radical mastoidectomy （patients in both groups underwent plastic repair of cavity of concha and mastoid plombage）. Dry ear time of the two groups was compared. Results The dry ear time of group B （59.28 ± 14.77d） was much shorter than that of group A （96.25 ±39.33d） after modified radical mastoidectomy（P〈0.01）. Conclusion Plastic repair of cavity of concha, mastoid plombage, and thorough removal of pathological tissues are the keys to shorting the dry ear time after modified radical mastoidectomy.
