Physiological function of the paranasal cavities
According to VL Fridman (Zhurn. Ushn., Nos. And Gorl. B., 1925, No. 11-12), the air sinuses are a hydrostatic apparatus, like the swim bladder of fish and the pneumatic bones of birds, adapted for the purpose of flying. In addition to this main function, they play the role of voice resonators.
