Abstract:
When fitting hearing aids, patients are required to make an earmold impression material for device fixation. It usually causes no problems, although in rare cases, the earmold passes through the middle ear through tympanic membrane perforations.1-3 Foreign bodies may cause a delayed inflammatory reaction and deterioration of aeration, especially in the Eustachian tube. Herein, we report a rare case of earmold impression material as a foreign body in the middle ear that required surgical removal.
