Audiometría con extensión en altas frecuencias (9.000-20.000Hz). Utilidad en el diagnóstico audiológico

Abstract

Esta es la versión de autor del artículo publicado en: This is an author produced version of a paper published in:Acta Otorrinolaringológica Española 67.1 (2016) Abstract Early detection and appropriate treatment of hearing loss are essential to min-imise the consequences of hearing loss. In addition to conventional audiometry (125---8000 Hz), extended high-frequency audiometry (9000---20 000 Hz) is available. This type of audiometry may be useful in early diagnosis of hearing loss in certain conditions, such as the ototoxic effect of cisplatin-based treatment, noise exposure or oral misunderstanding, especially in noisy environments. Eleven examples are shown in which extended high-frequency audiometry has been useful in early detection of hearing loss, despite the subject having a normal conventional audiometry. The goal of the present paper was to highlight the importance of the extended high-frequency audiometry examination for it to become a standard tool in routine audiological examinations.

Utilidad en el diagnóstico audiológicoResumen La detección precoz y el tratamiento adecuado de la hipoacusia es fundamental para minimizar las consecuencias de la pérdida auditiva. Además de la audiometría convencional (125-8.000 Hz), disponemos de la audiometría con extensión en altas frecuencias (9.000-20.000 Hz), que puede ser de gran utilidad en el diagnóstico precoz de hipoacusia en ciertas patologías, como es el efecto ototóxico de los tratamientos quimioterápicos, la exposición a ruido o el mal entendimiento del lenguaje, especialmente en ambientes ruidosos. Aquí se presentan 11 casos clínicos en los que la audiometría con extensión en altas frecuencias ha ayudado en la detección precoz de la hipoacusia en diversas patologías, a pesar de tener una audiometría normal en frecuencias convencionales. Se pretende así destacar la importancia de la exploración audiométrica en altas frecuencias, con el fin de que se convierta en una herramienta habitual en la exploración audiológica PALABRAS CLAVE Audiometría con extensión en altas frecuencias; Hipoacusia; Tinnitus; Presbiacusia; Cisplatino

Valencia’s Cathedral Church Bell Acoustics Impact on the Hearing Abilities of Bell Ringers

“…According to the published literature [16], the hearing loss at conventional frequencies (125 dB–8000 dB) in our study was lower than expected. Although there are statistically significant differences between the experimental group and the control group (at 2000–10,000 Hz), with the average hearing threshold being higher among the bell ringers, the loss is small.…”

“…High frequencies intervene in the location of sound [17] and the understanding of language, especially in noisy environments [18]. They have also been related to Presbycusis, ototoxicity and acoustic trauma [16]. Different studies establish the usefulness of audiometry with extension in high frequencies in the early detection of hearing loss associated with ototoxics, mainly in chemotherapy trea TDH ents with cisplatin and, to a lesser extent, methotrexate and cyclophosphamide [16,19].…”

However, there is controversy about its usefulness in the detection of noise induced hearing loss, since we lack conclusive data at the present time.…”

Examination of Hearing in a Rheumatoid Arthritis Population: Role of Extended-High-Frequency Audiometry in the Diagnosis of Subclinical Involvement

“…An early intervention in this subgroup of patients may cease the development of hearing loss. Thus, we propose that HFA should be performed as a routine screening not only for the study of RA but also for all of the inner ear disorders [ 26 , 28 , 43 ]. This should be taken into consideration not only before a treatment which may cause possible inner ear damage is performed but also along a long-term treatment such as the one received in patients with RA.…”

Current audiological diagnostics

“…For examination at higher frequencies, the frequency is increased in steps of sixths octaves up to 16 kHz (DIN EN 60645-1:2015-11). Measurement of the hearing threshold in the high frequencies, which is only possible with few standardized earphones (DIN EN 60645-1:2015-11), is only necessary and useful in the context of particular questions [ 9 ]. Those are for example the evaluation of the hearing abilities in the elderly [ 10 ], the early detection of ototoxic effects [ 11 ], [ 12 ] as well as the early detection of noise-induced hearing impairment [ 13 ], [ 14 ], [ 15 ].…”
