摘要
背景：開放式乳突鑿開術是治療膽脂瘤的標準術式之一，雖然它具有較低復發率的優點，但是術後卻可能有需定期清理耳道、易耳漏、眩暈、感染、進水後易頭暈、聽力重建較差等缺點。本研究在於探討乳突填塞術對有開放性乳突腔為其併發症所困擾，且經保守性治療效果不佳都之療效。 方法：利用自體骨、軟骨、或皮瓣填塞病人之開放性乳突腔。 結果：新光醫院收集自民國81年9月至民國86年4月間具上述情形之15名病患，施以乳突填塞術，這15名病人至本院就診以耳漏主訴者佔10名，接受乳突填塞術後有80%（8/10）獲得完全改善、20%（2/10）有些許改善；以聽力障礙為主訴者佔2名，接受乳突填塞術後有50%（1/2）並無明顯改善；以耳道反復發炎為主訴者佔2名，接受乳突填塞術後均有明顯改善；以眩暈為主訴者佔1名，接受乳突填塞術後已有明顯改善。

Background: Open-technique mastoidectomy is an option of operations for treating cholesteatoma. In spite of the advantage of lower recurrence, it may have the complications such as cleaning canal periodically, recurrent otorrhea, vertigo, infection, etc. This study shows what benefit can get for patients suffering form above symptoms with poor conservative treatment response after mastoidectomy obliteration. Methods: We reconstructed the opencavity mastoids with homograft (bony chip, cartilage, or flap) for those patients with above symptoms at our hospital. Result: In this report, there are 15 cases treated by mastoidectomy obliteration. Ten patients had the chief complication of otorrhea and 80% (8/10) of them have complete recovery and 20% (2/10) partial recovery after mastoidectomy obliteration. Two patients had the chief complication of hearing impairment and 50% (1/2) of them gets hearing improving after mastoidectomy obliteration. But the other doesn’t. Two patients had the chief complication of recurrent infections and they all had obvious improvement after mastoidectomy obliteration. One patient with the chief complication of vertigo had obvious improvement after mastoidectomy obliteraion. Conclusion: Mastodectomy obliteration is a good treatment for those patients who have open mastoid cavity suffering from their complication with poor medical response.
