Abstract

Among persons with intellectual disability, the prevalence of hearing impairments is high. During the German Special Olympics Summer Games 2004, a hearing screening was conducted on 755 athletes with intellectual disabilities. Obligatory screening included ear inspection and recording of otoacoustic emissions, and optional screening included tympanometry and brief pure-tone audiometry. 38.0% of the athletes failed the screening. 53.0% needed ear wax removal. 56.1% of the fails indicated sensorineural hearing loss and 13.6% indicated mixed hearing loss. 12.5% of the fails were caused by unremovable ear wax, 1.4% by ear canal affections, and 16.4% by middle ear problems. Left ear fails were more frequent than right ear fails. A peripheral hearing disturbance can thus be expected in every third subject. The high failure rate, a considerable percentage of previously undetected profound hearing loss (1.1%), and the frequent need for ear wax removal, suggest that nearly half of persons with intellectual disabilities need regular otological or audiological consultations.

Sumario

La prevalencia de hipoacusia entre personas con discapacidad auditiva, es alta. Durante los juegos olímpicos de verano 2004 en Alemania, se realizó un tamiz auditivo en 755 atletas con discapacidad intelectual. Éste incluyó otoscopia, prueba de emisiones otoacústicas y opcionalmente una timpanometría y una audiometría breve. El 38% de los atletas no pasaron el tamiz y a 53% se les retiró cerumen. El 56.1% de los que no pasaron el tamiz presentaban hipoacusia sensorineural y 13% hipoacusia mixta; a 12.5% no fue posible retirarles el cerumen, 1.4% presentaban alteraciones del conducto auditivo externo y 16.4% tenían algún problema del oído medio. Fueron más frecuentes las alteraciones en el oído izquierdo que en el derecho. Se puede esperar una alteración auditiva periférica en un tercio de los sujetos. El alto índice de falla en el tamiz, un porcentaje considerable de hipoacusia profunda no detectada (1.1%) y la necesidad frecuente de remoción de cerumen, sugiere que casi la mitad de las personas con discapacidad intelectual necesitan consulta audiológica u otológica regular.
