title: Investigation of the blood flow in the maxillary sinus.
abstract: 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.
