Introducción y objetivo: La timpanometría de baja frecuencia (226 Hz) se considera un procedimiento ineficaz para el diagnóstico de la otitis media serosa en los primeros 6 meses de la vida. Con la implantación del cribado auditivo universal, se recomienda la utilización de la timpanometría de alta frecuencia de 1.000 Hz. A fin de optimizar el diagnóstico de la hipoacusia neonatal presentamos este trabajo donde comparamos, desde el punto de vista clínico, los resultados timpanométricos de 226 Hz y de 1 kHz. Material y método: Estudio prospectivo de 100 niños menores de 9 meses procedentes del cribado auditivo. Comparamos el resultado de la timpanometría con la otomicroscopia y con las otoemisiones acústicas transitorias. Resultados: La aplicación de las otoemisiones acústicas transitorias, la otomicroscopia y la timpanometría de 226 Hz y de 1 kHz ha mostrado su utilidad en el manejo de la otitis media serosa del lactante, con una validez similar entre las 4 pruebas. Conclusión: El uso conjunto de la otomicroscopia, las otoemisiones acústicas transitorias y la timpanometría de 226 Hz y de 1 kHz nos ha permitido diagnosticar la otitis media serosa del lactante con mayor precisión que si aplicáramos estas pruebas de forma aislada. Se aconseja utilizar inicialmente la timpanometría de 1 kHz, al menos en niños menores de 7 meses, pero en presencia de hipoacusia o de un resultado confuso, la timpanometría de 226 Hz es un buen complemento diagnóstico (AU)
Introduction and objective: In the first 6 months of life, 226 Hz tympanometry is considered an ineffective procedure for the diagnosis of otitis media with effusion. With the introduction of universal hearing screening, the use of high frequency 1000 Hz (1 kHz) tympanometry has been recommended. To optimise the diagnosis of neonatal hearing loss, we present this comparison, from the clinical point of view, of the results of 226 Hz and 1 kHz tympanometry in infants. Materials and methods: We designed a prospective study of 100 children under 9 months of age proceeding from our hearing screening program. We compare the result of tympanometry with binocular microscopy and transient evoked otoacoustic emissions. Results: The application of transient otoacoustic emissions, otomicroscopy and 226 Hz and 1 kHz tympanometry has shown its usefulness in the management of otitis media with effusion of young infants, with a similar effectiveness between the 4 tests. Conclusion: The joint use of otomicroscopy, transient otoacoustic emissions and 226 Hz and 1 kHz tympanometry, has allowed us to diagnose otitis media with effusion in young infants more accurately than each test separately. We recommend initial use of 1 kHz tympanometry, at least in children younger than 7 months, but in the presence of hearing loss or an unclear result, 226 Hz tympanometry is a good diagnostic complement (AU)

INTRODUCTION AND OBJECTIVES: We present the results from applying over a period of three and a half years a universal newborn hearing screening programme aimed at the early detection of hearing loss. Our goal has been to diagnose and treat all unilateral or bilateral permanent hearing losses > or =40 dB nHL. METHODS: The detection strategy consists of two screening phases with transient evoked otoacoustic emissions (TEOAE) and one diagnostic phase with auditory brainstem responses (ABR). ABR tests were performed on newborns "not passing" the TEOAE screening, as well as those with risk factors for hearing loss. RESULTS: Of 4568 live newborns (NB), we evaluated 97.6 %. Of these, 3.7 % presented risk factors for hearing loss. The first TEOAE was "passed" in both ears by 91.7 % of the newborns; after the second TEOAE, only 1.3 % of cases were referred to the diagnostic phase. We detected 2.7/1000 cases of severe/profound bilateral hearing loss. CONCLUSIONS: This programme was designed for early application of appropriate treatment. Although it is possible to reach the objectives of screening and diagnosis of newborn hearing loss, the intervention stage is much more complicated. This is because intervention depends on different disciplines that must act in co-ordination, as well as multiple environmental and family factors that are difficult to control. Therapeutic effectiveness still remains our challenge and a motive for discussion in fully justifying early congenital hearing loss screening programmes.

Introducción y objetivos: Presentamos los resultados de aplicar durante 42 meses un programa de detección precoz universal de la hipoacusia neonatal. Nuestro objetivo ha consistido en diagnosticar y tratar todas las hipoacusias permanentes unilaterales o bilaterales $ 40 dB nHL. Métodos: La estrategia de detección consta de 2 fases de cribado con otoemisiones acústicas transitorias (OEAT) y una fase de diagnóstico con potenciales evocados auditivos del tronco cerebral (PEATC). Los PEATC se realizaron tanto a los que no pasaban el cribado con OEAT como a los neonatos con factores de riesgo de hipoacusia. Resultados: De los 4.568 recién nacidos (RN) vivos, hemos evaluado al 97,6 %. Un 3,7 % de los nacidos presentaba factores de riesgo de hipoacusia. El 91,7 % de neonatos pasó la primera OEAT en ambos oídos, y tras la segunda sólo se derivó a la fase de diagnóstico al 1,3 %. Hemos detectado 2,7 hipoacusias severas-profundas bilaterales/1.000. Conclusiones: La finalidad de este programa reside en la aplicación precoz del tratamiento adecuado. Aunque resulta posible alcanzar los objetivos de cribado y diagnóstico de la hipoacusia neonatal, es mucho más complicada la fase de intervención, pues depende de diferentes disciplinas que deben actuar coordinadamente y múltiples factores ambientales y familiares difíciles de controlar. La efectividad terapéutica sigue siendo nuestro reto y el motivo de discusión para justificar plenamente los programas de detección precoz de la hipoacusia congénita
