Method for enhancing eustachian tube patency and treatment of otitis media

A method for enhancing eustachian tube patency in a human patient utilizing an eustachian tube targeting nasal administration device wherein said device comprises an administration housing having a canister containment section and a delivery nozzle section, said method comprising:

• inserting a canister containing a selected mixture consisting of a selected surfactant constituent and a selected propellent constituent into the canister containment section of the administration device;
• positioning the device so that a delivery nozzle, depending from a front surface of the delivery nozzle section, having a central bore demonstrating a longitudinal axis and openings at a proximal and distal end in fluid communication therewith, is placed within and enters a nostril on a selected side of patient's face;
• further positioning the device so that an elevation alignment arrow, formed upon side surfaces of the delivery nozzle section, points towards a tragus portion of an ear located on the same side of the patient's face as the nozzle was placed and entered;
• activating the canister so that a portion of the mixture of surfactant and propellant is released from the canister, flows through conduits formed within the delivery nozzle section and thereafter flows through the central bore of the delivery nozzle and, due to a uniform, constant and selected diameter of the openings of the proximal end, distal end and the central bore of the delivery nozzle, forms and releases a collimated stream of the mixture from the distal end thereof;
• whereupon, due to the positioning and configuration of the device, the collimated stream released by the delivery nozzle is directed towards a pharyngeal orifice of the eustachian tube, thereafter rapidly reaching and entering into a central lumen of the eustachian tube whereupon the mixture lowers the opening pressure thereof.

• positioning the device so that an elevation alignment arrow, located upon side surfaces of the delivery nozzle section and oriented so as to be in parallel alignment with the longitudinal axis of the central bore of the delivery nozzle, points towards a tragus portion of an ear on the same side of the patient's face as the nostril into which the delivery nozzle is placed and enters;
• activating the canister so that a portion of the mixture of surfactant and propellant is released from the canister, flows through conduits formed within the delivery nozzle section and thereafter flows through the central bore of the delivery nozzle wherein, due to a uniform, constant and selected diameter of openings at the proximal end, the distal end and a central bore thereof, the delivery nozzle, forms and releases a collimated stream of the mixture from the distal opening thereof and, due to the size, shape, configuration and positioning of the device, the collimated stream is directed towards the pharyngeal orifice of the eustachian tube, whereupon, the mixture of surfactant and propellant rapidly reaches and enters into a central lumen of the eustachian tube wherein the surfactant lowers the opening pressure of the eustachian tube thereby providing increased patency so as to enable draining of byproducts of otitis media from the middle ear chamber and relief of increased pressure of the middle ear chamber associated therewith.
