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.
为有需要的儿童准备耳模以配助听器时，很少会出现并发症。然而，我们遇到了 2 例患者，他们在硅橡胶印模取模后很长时间后，中耳内仍有异物残留。1 例患者是在取模后 2 年后出现症状，另 1 例患者则在佩戴助听器 10 年后出现症状。我们报告了 2 例在取模后很长时间内，硅橡胶印模材料遗留于中耳的病例，这些病例是在进行探查性鼓室切开术时意外发现的。这些报道的病例在全球范围内较为罕见，其确切的发病率尚不清楚。这就需要耳鼻喉科医生和负责取模的听力学家进行适当的检查，以预防此类并发症。
