Pathophysiology of the Paranasal Sinuses

Acta Oto-Laryngologica, 1977
The maxillary ostium is narrower when the subject is recumbent than when sitting. The oxygen content in the sinus is related to the patency of the ostium and to some extent to its size. A 90% gas exchange in the sinus normally requires only 5 minutes. The exchange is faster during nasal than during oral breathing.

The Function of the Paranasal Sinuses

Acta Oto-Laryngologica, 1954
