Ceppo,
Grommits are small cylinder shape devices that some chidren (maybe adults, I don't know) have inserted in their inner ear to drain away excess fluid. The process requires an operation under anesthetic at the hospital (well it did when I was a kid-I bet it's done under a local now and you get let out after half an hour!! Ah, NHS cutbacks-you can't beat 'em!).
Grommits are about half a millimeter in length and usually drop out after a year or so and evidently leave some scaring.
Hope that helps.
Take care, VFE.
