Hearing Aid Silicone Impression Material Discovered During Exploration of the Middle Ear: 2 Case Reports and...

It is unusual to see complications with the preparation of ear mold in order to get hearing aids for children who are in need. However, we came across 2 cases who had a foreign body retained in the middle ear after a long period of time from taking silicon mold impression for hearing aid fitting. One patient presented after 2 years, and the other patient presented after 10 years of hearing aid fitting. We are reporting 2 cases with silicon impression material left in the middle ear for a long period of time after taking an impression for hearing aid fitting and found unexpectedly during exploratory tympanotomy. These reported cases are among the few cases reported worldwide without clear known incidence. This necessitates proper examination by otolaryngologists and the audiologists who are responsible for taking the impression to prevent such complications.
