While I'm a "senior" definitely not a little kid which Otovent is primarily designed for it's made all the difference in the world in clearing my glue ear problem. I've had this condition for years culminating in my getting pneumonia in January - mid summer in Australia! My respiratory doctor has got me onto a treatment plan which has push back the overwhelming mucus I was getting but my glue ear still hung around. The valsalva maneuver my ENT doctors got me onto were not effective enough. Looking around on the web I came across this blog https://glueearsuccess.wordpress.com/ who said that Otovent was the solution to his glue ear problem. So I bought one and tried it. It cleared my glue ears in three days well inside its recommended maximum usage of two weeks. In mechanistic terms it achieves a sort of enhanced valsalva maneuver.
