Plethysmographic measurements of the blood flow in the mucosa of the human maxillary sinus was reported in 1974, but the errors of the method were not completely known. By measuring the absorption of the radioactive gas 133Xe by the antral mucosa simultaneously with plethysmography a comparison between the two methods is possible. A good correlation between the two methods was found in the only subject investigated so far.
1974年报道了用体积描记法测量人上颌窦黏膜血流的情况，但该方法的误差尚不完全清楚。通过在进行体积描记法的同时测量放射性气体133Xe被窦黏膜的吸收情况，两种方法之间可以进行比较。在迄今为止所研究的唯一一名受试者中，发现两种方法之间有良好的相关性。
