In 141 ears with central tympanic membrane (TM) perforation preoperative tubal studies as well as volume determination of the air-filled ear spaces was performed. Tubal patency was checked with Valsalva's manoeuvre and pressure equilibration function with Toynbee's test and aspiration-deflation tests respectively. At postoperative control 74.5% of the ears had intact movable TM (healed), 5.7% had intact but immovable or retracted TM and 19.8% had perforation (defect). There was no difference between the healed and defect ears regarding results in aspiration-deflation tests. A positive Valsalva's manoeuvre was significantly more frequent in the healed ears. Ears with a small air-filled volume and negative Valsalva's manoeuvre showed significantly lower healing rate than ears with positive Valsalva's manoeuvre and a large air-filled volume.
对141例中心性鼓膜穿孔患者进行了术前咽鼓管检查以及气腔耳腔容积测定。分别通过瓦尔萨尔瓦动作检查咽鼓管通畅情况，通过汤因比试验和抽吸-放气试验检查压力平衡功能。术后复查时，74.5%的耳鼓膜完整可活动（愈合），5.7%的耳鼓膜完整但不可活动或内陷，19.8%的耳存在穿孔（缺损）。在抽吸-放气试验结果方面，愈合耳与缺损耳之间没有差异。瓦尔萨尔瓦动作阳性在愈合耳中明显更为常见。气腔容积小且瓦尔萨尔瓦动作阴性的耳，其愈合率明显低于瓦尔萨尔瓦动作阳性且气腔容积大的耳。
