The aim of this study was to assess whether patients with open mastoid cavities should be advised to avoid water contaminating the ear in order to avoid aural discharge. A detailed history and clinical examination was performed on 53 patients with a unilateral modified radical mastoid cavity of more than 5 years duration. The results showed that it is possible to identify reliably the well-designed trouble-free cavity by the features of its skin lining and the ability to visualize the entire cavity through a size 4 Siegle speculum. A patient with this form of cavity very rarely develops aural discharge following water exposure and need not protect the ear during washing but should do so when swimming because of caloric effects.
本研究的目的是评估是否应建议开放乳突腔患者避免水进入耳朵以防止耳漏。对53例单侧改良根治性乳突腔病程超过5年的患者进行了详细的病史询问和临床检查。结果表明，通过乳突腔皮肤衬里的特征以及使用4号西格尔窥镜观察整个乳突腔的能力，可以可靠地识别设计良好且无问题的乳突腔。具有这种乳突腔形式的患者在接触水后很少发生耳漏，在洗澡时无需保护耳朵，但由于热效应，游泳时应加以保护。
