I think the detractors of "syringing" are all being a bit lightweight
That may be your view, and you are, of course, entitled to it.
In a 35 year career in General Practice I have seen numerous ears severely damaged by injudicious or inappropriate syringing.
Current ENT (otorhinolaryngology) best practice is that ear syringing is risky at the very best, and best avoided. And the annual reports of the Defence Organisations are just FULL of cases resulting from syringing !
Why risk it, when there are simpler and safer ways . . . . . . . ?
