Abstract
|
|
|
As no one has ever tried to observe the composition of gas in maxillary, sinus which belongs to the category of "non-ventilated-open" gas pocket, we analyzed the gas sample taken from maxillary sinus cavity of normal persons and sinusitis patients.
The findings were as follows:
1. The mean concentration of oxygen, carbon dioxide and nitrogen in maxillary sinus cavity from the fifteen normal persons were 16. 01%, 3. 57% and 80.42% respectively. This values of gas concentration are very close to that of expired air at resting state.
2. The concentration of those gases taken from maxillary sinus cavity of six chronic sinusitis patients were not different significantly from that of normal persons.
3. The composition of gases in maxillary sinus cavity indicates that oxygen is absorbed into and carbon dioxide liberated from the mucous membrane of the cavity continuously and the same time the sinus is ventilated some extent through the natural opening, possibly intermitently.
