Abstract

We report a case of methicillin-resistant Staphylococcus aureus (MRSA) otorrhea with impression material of hearing aid in the middle ear. The patient had chronic otitis media in the right ear with sensorineural hearing loss in both ears. The silicone flowed into the middle ear through a tympanic membrane perforation during the process of making an ear mold. Several days after hearing aid fitting, the patient had severe otalgia, intractable otorrhea, aggravated hearing loss, and dizziness. The pus culture and sensitivity test revealed MRSA. After topical treatment using diluted vinegar irrigation and ototopical vancomycin solution, intractable otorrhea was controlled. The infected silicone impression was removed by canal wall-up mastoidectomy, and hearing was saved. We present here a review of the literature regarding silicone impression in the middle ear after hearing aid mold fitting.
