Earmold Impression Material Foreign Body in the Middle Ear as a Hearing Aid Impression Complication: A Case Report

Hearing aid is an electronic device fitted to the ear and designed to amplify and deliver sound to the ear. Upon fitting a hearing aid, patients are required to make an earmold impression material for device fixation based on patient’s personal preference, the shape and texture of the ear. Complications while making an earmold for hearing aids are rare but during this process, the impression material can be accidentally entered in the middle ear through a perforation on the tympanic membrane. Here we report a case of 60 years old Chinese gentleman with a foreign body in the middle ear during earmold impression procedure in a private hearing aid centre. Removal of earmold impression material in middle ear was performed under general anesthesia without serious complications.
