THERMODYNAMIC MODEL FOR MIDDLE-EAR VENTILATION - DEFINING THE D-ORGAN BY COMPARISON TO THE EUSTACHIAN TUBE (RE-INTERPRETATION OF A CLASSIC EXPERIMENT AND REVIEW OF LITERATURE)

Marian RĂDULESCU, Horia MOCANU, Alexandru NECHIFOR, Adela Ioana MOCANU

Abstract


The analysis employes Claude Bernard’s physiological method of establishing the function of internal organs to reinterpret a classical experiment by Yee A.L. & Cantekin E.I. The surprising results could only be explained by the existence of the D-Organ (The Danaïdes Organ) which we define within the middle-ear (ME) and compare to the Eustachian tube (ET) in terms of middle-ear ventilation. Its function could only be completely defined via a physical-mathematical model. The ventilation of the middle-ear is therefore achieved by the D-Organ, a biological pump, consuming metabolic energy to move gases against pressure gradients and the F-Organ with role in passive diffusion of gas using pressure gradients, in accordance to Fick’s law.
