We investigated the otological condition of young patients with otitis media with effusion (OME). Of the patients who underwent the first insertion of ventilation tubes from April 1993through March 1994,55 children (103 ears) have been followed up so far. Their ages ranged from 2to 11 years. Eleven of 55 children were still affected with OME either unilaterally or bilaterally. Their refractory cases accounted for 20.0%. Crucial factors for refractory OME include age of the first onset of OMA or OME, condition of the tympanic membrane, existence of cholesterin crystals in effusion in the middle ear, and maturity of the mastoid antrum.

A 14-year-old female had been suffering from a click in both ears for two years. The tinnitus could be heard objectively. Endoscopic examination showed that the soft palate repeatedly touched and separated from the posterior wall of the nasopharynx, in sychrony with the click. Sonotubometry revealed spontaneous opening and closing of the eustachian tube which synchronized with movement of the soft palate. A sound-spectrogram indicated that the duration of the tinnitus was 60-70msec, and the frequency range was 1500-8000 and 9000-16000 Hz. All the findings showed that the click originated from the soft palate and the eustachian tube.

Clinical Laboratory Centor, Kansai Medical University Hospital Department of Pediatrics, Kansai Medical University Kori Hospital Department of Pediatrics, Kansai Medial University This study compares the clinical usefulness of DPOAEs with ABR for children for the evaluation of hearing impairment. Both DPOAEs and ABR were performed on 43 children (14 days to 10years) (62 ears). (1) We could not obtain DPOAEs at f2=537 Hz in children with normal hearing because of high noise floors; (2) We defined as normal DPOAEs, the number of frequencies which showed the DP gram-noise floor≥4 dB was≥four at seven f2 frequencies, fom 977 Hzto 7,959 Hz; (3) The results of DPOAE were different from ABR in children with otitis media erosiva; (4) Two patients with no ABR response showed positive DPOAE over 4,004 Hz. Our study indicates that DPOAEs represent a simple procedure, which can be performed easily to obtain reliable results in children.
