“…Hearing loss was present in 67% of the cases in this group. Other authors have published similar results [7,26]. The relatively high number of children with severe hearing loss in our study can be explained by the sizable subgroup of children with hearing loss risk factors.…”

“…It is known that children with Down's syndrome have secretory otitis media with considerable frequency, but these two cases did not have this condition. Harigai reports a transient retardation of auditory development, especially in children with Down's syndrome (2). He suggests that retardation of the development of the central nervous system, including myelination, might increase the ABR threshold in some cases.…”

“…These phenomena were considered to be a consequence of the immaturity of the auditory system. Harigai (2) and Hattori et al (3) report that auditory development may be retarded in children with Down's syndrome because of immaturity of the central nervous system. However, details of these phenomena have not been elucidated.…”

Kawarai H, Nishizaki K, Fukuda S, Akagi S, Inokuchi I, Gunduz M, Masuda A, Nakashima T, Fukushima K, Masuda Y.Hearing immaturity found by ABR and its clinical impact on otoneurological e6aluation. Acta Otolaryngol (Stockh) 1999; Suppl 540: 6 -11. Auditory Brainstem Response (ABR) is the most reliable and most frequently used procedure to evaluate audiological conditions in early infancy. However, several reports have demonstrated that developmental change in the central nervous system may affect the results of ABR in audiological evaluations. We examined statistically the reliability of ABR for the diagnosis of profound deafness in early childhood according to our experience over the past 12 years of follow-up in our facility. Subjects included 371 children among 1,041 children who were admitted to Kanariya-Gakuen (institute for pre-school deaf children) from April 1985 to March 1997. These children were examined with ABR to determine their hearing levels. In five cases with an abnormal hearing threshold determined by ABR and other audiological tests, repeated examinations carried out during a 5-to 6-month follow-up period revealed that they had normal hearing. Three of these children had been diagnosed previously with mental retardation and the remaining two were infants B 5 months old. The specificity and sensitivity of ABR were calculated as 97.3% and 100%, respectively. The predictive value of a positive result was 94.7%. There remains the possibility of a false negative for such cases, although the rate seems to be very low (B 0.2%). Key words: Auditory Brainstem Response, deafness in children, hearing impairment, predicti6e 6alue of positi6e result, retardation of auditory de6elopment, sensiti6ity and specificity.

“…Longstanding middle ear disease and early osteoid deposition in the fundus of the internal auditory canal in the region of the spiral tract have been implicated in the progression of SNHL in DS 4,5 . Aggressive treatment is beneficial in reversing some of the conductive hearing loss related to chronic otitis in DS 6–8 . However, patients with DS do not improve as much as other patients after myringotomy, adenoidectomy, and removal of cholesteatoma.…”

Inner Ear Dysplasia is Common in Children With Down Syndrome (trisomy 21)

et al. 2006

Inner ear dysplasia is much more common in DS than previously reported. Inner ear structures are universally hypoplastic. Vestibular malformations are particularly common and a small bony island of the lateral semicircular canal (<3 mm in diameter) appears highly typical. Additional findings in some patients were persistent lateral semicircular anlage with fusion of the lateral semicircular canal and vestibule into a single cavity, vestibular aqueduct and endolymphatic sac fossa enlargement, cochlear nerve canal hypoplasia, and stenosis or duplication of the internal auditory canal. Stenosis of the external meatus, poor mastoid pneumatization, middle ear and mastoid opacification, and cholesteatoma were common, as expected.
