  • Abstract
  • Look Inside

 With each respiration interchange of air occur between the sinus cavity and that of the nasal. The course with which this interchange takes place has been reported elsewhere.

 Anatomically, the size of the natural ostium plays an important role in the mechanism of this air-interchange.

 Experimentally, the size of the natural ostium and the corresponding changes of air pressure that may occur within the sinus cavity have been studied.

 Normally, when the natural ostium has an opening of 4mm in diameter the intrasinus air pressure would amount to about±6 mmH2O. These tests have repeatedly conducted also on cadavers and confirmed by using smoke as indicator.
