Abstract: A prophylactic method for preventing otitis media or Eustachian tube dysfunction, or reducing the severity of symptoms thereof, decreasing the risk of future otitis media, with or without ear infection, and associated effects including acute or permanent hearing loss, speech and balance problems, behavior problems and sleep problems caused by acute, intermittent episodic, recurrent or chronic otitis media, and the need for surgical interventions involving myringotomy such as ear tubes for chronic middle ear effusions, or tympanic membrane perforation for acute drainage of effusion from the middle ear and ventilation of the middle ear, through the nasal delivery of surfactant to the Eustachian tube(s).

Abstract: A compound, process and method for increasing external auditory canal patency while simultaneously preventing the occurrence of otitis externa is disclosed wherein an aerosolized mixture of lipid crystals comprised of a mixture of one or more lipids surfactants and one or more spreading agents selected from the group consisting of sterols, lipids, fatty acids, cholesteryl esters, phospholipids, carbohydrates, nucleic acids and proteins, in powder form, and one or more fluorocarbon propellants is administered directly to the external auditory canal. Upon administration, the propellant(s) are evaporated from the mixture and the lipid crystals are deposited upon an air/liquid interface resident upon epithelial tissue lining the external auditory canal.

Abstract: A process, composition and method for increasing and enhancing mammalian eustachian tube lumen patency and pressure equalization performance is disclosed wherein an aerosolized mixture of lipid crystals comprised of a mixture of one or more lipids surfactants and one or more spreading agents selected from the group consisting of sterols, lipids, fatty acids, cholesteryl esters, phospholipids, carbohydrates, and proteins, in powder form, and one or more propellants, in which the lipid surfactants and spreading agents are not soluble, are administered through a mammalian airway orifice. Upon administration, the propellant(s) are evaporated from the mixture and the lipid crystals are deposited within a subject mammalian eustachian tube whereupon said lipid crystals come into contact with lumen surfaces of the tube forming an amorphous spread film thereupon substantially decreasing the opening pressure of the lumen.

Abstract: The present invention discloses a method of decreasing airflow resistance through the mammalian upper respiratory system by administering an aerosolized mixture of lipid crystals comprised of a mixture of one or more lipids surfactants and one or more spreading agents selected from the group consisting of cholesteryl esters, phospholipids, carbohydrates and proteins, in powder form, and one or more fluorocarbon propellants, through nasal or oral inhalation. Upon administration, the propellant(s) are evaporated from the mixture and the lipid crystals are deposited upon the air/liquid interface resident upon epithelial tissue lining air ways and air spaces of said upper respiratory system. Upon contact of said lipid crystals with the air/liquid interface, an amorphous spread film is formed thereupon substantially decreasing the surface tension of said lining and resulting in an increase in volume of said airways and airspaces.
