The grommet can leave some scarring in the eardrum; this does not usually affect the hearing.

Can grommets cause hearing loss?

There are some other rare complications of grommets, including hearing loss, or middle ear problems as a result of eardrum skin being pushed in when the grommet is inserted (cholesteatoma).

How quickly does hearing improve after grommets?

It usually clears up within 3 months, but see a GP about any hearing problems.
