Objective confirmation of nasolacrimal patency following dacryocystorhinostomy is a desirable postoperative goal for both the surgeon and the patient. The authors describe a simple method to demonstrate dacryocystorhinostomy patency and present a study comparing the effectiveness of this novel test with Jones fluorescein testing in 32 cases seen consecutively at postoperative follow-up. The test consists of demonstrating reflux of air through the dacryocystorhinostomy as the patient performs the Valsalva maneuver. This reflux is most easily seen as bubbles rising through a drop of saline placed in the medial canthus. A high correlation was found between this test and Jones testing. The Valsalva dacryocystorhinostomy bubble test (VBT) appears to be a fast, safe, and accurate method of confirming dacryocystorhinostomy patency.
泪囊鼻腔吻合术后鼻泪管通畅的客观确认，是外科医生和患者都期望达到的术后目标。作者描述了一种证明泪囊鼻腔吻合术通畅的简单方法，并展示了一项研究，该研究比较了这种新测试与琼斯荧光素测试在术后随访中连续观察的32例病例中的有效性。该测试包括在患者进行瓦尔萨尔瓦动作时，证明空气通过泪囊鼻腔吻合口反流。这种反流最容易通过置于内眦的一滴盐水中升起的气泡观察到。该测试与琼斯测试之间发现高度相关。瓦尔萨尔瓦泪囊鼻腔吻合气泡测试（VBT）似乎是一种快速、安全且准确的确认泪囊鼻腔吻合术通畅的方法。
