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.
