Grommet being the same as having tubes put in Hobo ?
Stilton, If you mean 'inner' tubes put in the Eustacian tubes like a catheter, then no. As I understand it they are like the rubber grommets in metal socket boxes to stop the wire insulation chaffing through - small discs with a hole in the middle, which are placed within the surface of the eardrum itself. Apparently, they come out by themselves in time as the hole the surgeon cuts in the eardrum slowly grows back and expels them automatically, like an earpiercing growing back solid.
