What is an Otoblock?
An otoblock is a sponge or piece of cotton that is used to prevent impression material from going too deep into the ear canal during the impression-taking procedure for a custom-fit hearing aid. The otoblock is typically placed at the first bend of the ear canal, which is the narrowest part of the canal. This helps to ensure that the impression material is properly distributed and that it does not enter the middle ear.
