The subjects were 13 children with a hearing deficit that had been missed until school age. Six children with mild hearing loss were not aware of their disease. Of the patients with moderate hearing loss, five children could not be diagnosed though their parents had been suspicious at an early stage. Delayed development of language was observed in 9 children, and the vocabulary of all the patients was poorer than the mean of normal children. Thus, it appears necessary to diagnose hearing loss in early childhood for the prevention of speech and language delay.
A medical examination for preschool-aged children is an important screening test to discover hearing, voice and speech disorders. It is the first opportunity chance for otolaryngologists to become involved directly in school health, but the purpose cannot be achieved sufficiently because of the limitations of time and technique. In the present study, an otolaryngologist conducted a medical examination with a speech-language-hearing therapist. The examination found that many children have a speech disorder. It has been found some of them are below average in development, their verbal IQ and performance IQ show estrangement and they do not merely have dyslalia.
We performed a cochlear implantation for a deafened 2 year old girl with ossified cochleae after meningitis. Ten electrodes were partially inserted using the Nucleus 22, but her hearing did not improve. One year later, re-implantation was performed using a total cochleostomy with the Nucleus 24M. She did not feel any sensation from electrical stimulation and did not display an NRT response. She wore a cochlear implant and a hearing aid in both ears without a hearing response. After 12months, she responded to her name. After 2 years, her hearing level was at 30 dBHL. We concluded that continuous electrical stimulation was effective in improving her hearing.
In this study, we investigated the applicability of the Kanazawa method and its efficiency for a child with multiple disabilities. We introduced language training for a child with hearing impairment, cerebral palsy, epilepsy and mental retardation from the age of 41 months. The child began to understand written language after 8 months. Immediate imitation of actions started after 12months. The number of words understandable by sign, written and auditory language became 46,37, and 12, respectively, after 15 months. The subject indicates that the Kanazawa method is effective even for children with mental retardation and disabilities in motion.
Eighty-two children, consisting of 60 males and 22 females who were suffering from language retardation, visited our department over the past two years and contributed to the study. The mean age of the children was 3 years and 3 months at the first consultation. Many of the children were referred to us by otolaryngologists who first found the impairment of language development. Around 88% of the children suffering from language retardation were affected by certain psychiatric problems such as mental retardation (fifty-four children,66%) and autism. Seven patients (9%) were affected by a considerable hearing deficit including five patients with severe hearing loss.
This report concerns the frequency of medication and/or medical therapy for 18 infants with hearing-impairment who were treated at Kanazawa University Hospital. Our study assessed the frequency of otitis media with effusion (OME) and/or chronic sinusitis in hearing-impaired children between January and December 2002. All the subjects were using hearing aids. At each visit to our clinic, an ENT doctor checked their ears, nose and throat. The children's history was checked by ENT doctors for OME and/or sinusitis. In all the subjects, ENT disease was identified during the one-year period. Therefore, we stress the importance of otorhinolaryngologic after-care for hearingimpaired children.
The newborn hearing screening test was introduced in 1999 in Japan. Subsequent to this test, our Department has also conducted a precise reexamination test. Accordingly,176 infants were examined in our Institute from 1999 to 2002. Of these,150 infants underwent the precise reexamination test and 26 did not as their parents refused the test. The results of the reexamination test showed that: 1 The number of candidates for the precise reexamination test has been increasing every year. 2 The number of infants who were examined by otoacoustic emission (OAE) outnumbered those examined by the automated auditory brainstem response (AABR). 3 These testing methods allowed a number of infants (n=31) with unilateral sensory neural deafness to be detected. 4 The accuracy of AABR testing was found to be higher as compared to that of OAE. The newborn hearing screening test has become a routine examination in Osaka Prefecture and has proved to be an efficient universal screening test battery for the early detection of deafness in infants.
We compared the nasal width and interorbital distance on plain radiographs taken using the Caldwell view. The nasal width never exceeded the interorbital distance in patients with stenosis of the entire nasal passage. Belenden measured the nasal width in patients with pyriform aperture stenosis and normal subjects on CT and recognized that it is markedly smaller in the former. I postulate that if the Caldwell view is used, the nasal width also never exceeds the interorbital distance in pyriform aperture stenosis, based on Belenden's data. Therefore, the Caldwell view will be a useful routine examination in nasal dyspnea. Pyriform aperture stenosis sometimes has two significant complications: a single central incisor and pituitary abnormalities. By contrast, it is unclear whether these two complications are present in stenosis of the entire nasal passage.
