Resistance measurement is a simple and practical mean of testing ostial function. The present study showed that the results of measuring the ostial resistance varied according to the amount of antral secretion. For that reason the postirrigational mean resistance is about 1/5 of the highest mean resistance in acute maxillary sinusitis. The average ostial resistance in healthy persons is 2.5 cm of water and in acute maxillary sinusitis at diagnostic puncture, 13.0 cm of water, and at the end of treatment, 3.3 cm of water. There are discrepancies between the results of resistance measuring and patency tests in 10-30% of cases. It is difficult to say whether these are due more to faults in the measuring techniques of the resistance or the patency. As an ostial function test, resistance measuring is quantitative and the testing of patency qualitative.
阻力测量是检测窦口功能的一种简单实用的方法。本研究表明，窦口阻力的测量结果会因窦腔分泌物的量而有所不同。因此，在急性上颌窦炎中，冲洗后的平均阻力约为最高平均阻力的1/5。健康人的平均窦口阻力为2.5厘米水柱，急性上颌窦炎诊断性穿刺时为13.0厘米水柱，治疗结束时为3.3厘米水柱。在10% - 30%的病例中，阻力测量结果与通畅性测试结果存在差异。很难说这些差异更多是由于阻力测量技术还是通畅性测试技术的缺陷所致。作为一种窦口功能测试，阻力测量是定量的，而通畅性测试是定性的。
