We report an 11-year-old girl, who suffered from Mycoplasma pneumoniae pneumonia, meningitis, and mild, bilateral, acute otitis media, with subsequent severe, mixed hearing loss. The patient presented extremely high Mycoplasma pneumoniae complement fixation and cold hemagglutinin titers, the unique chest x-rays indicating mycoplasma pneumonia, and cerebrospinal fluid suggestive of meningitis. A moderate grade of sensorineural hearing loss that was seen in the early clinical stage has not shown any improvement, although the other signs and symptoms have resolved. Possible causative relationships of Mycoplasma pneumoniae to otologic complications, especially those closely related to peripheral nerve impairments, were discussed
