Validación y confiabilidad del Cuestionario de Tamizaje Auditivo Escolar en adolescentes usuarios de reproductores de música comprimida.

INTRODUCCIÓN: El uso frecuente de reproductores de archivos de música y la intensidad del volumen son factores de riesgo para el desarrollo de hipoacusia. OBJETIVO: Validar el Cuestionario de Tamizaje Auditivo Escolar (CUTAE) para identificar alteraciones auditivas en adolescentes usuarios de reproductores de archivos música comprimida (RPAMC). MÉTODO: Se estudiaron adolescentes usuarios de RPAMC, sin hipoacusia ni patología de oído medio. Se aplicó el CUTAE y se realizó audiometría. Se determinó reproducibilidad (coeficiente correlación intraclase-CCI), consistencia interna (alfa de Cronbach), validez de apariencia (técnica Delphi), validez concurrente CUTAE-audiometría (correlación de Pearson) y validez predictiva (regresión múltiple) del cuestionario. RESULTADOS: Se evaluaron 59 adolescentes (118 oídos), 66 % del sexo femenino, con edad promedio fue de 13 años; 90 oídos con parámetros normales, 18 con umbral menor de 20 dB con morfología de trauma acústico (TA) en la frecuencia de 6 KHz y 10 con TA. El cuestionario tuvo CCI de 0.788, alfa de Cronbach de 0.807, correlación de Pearson de 0.290 a 0.368 (p < 0.05); las variables predictivas fueron horas de uso del dispositivo, dificultad para escuchar a las personas (p < 0.05) y tipo de zumbido (p = 0.07). CONCLUSIÓN: El CUTAE tiene propiedades clinimétricas para considerarlo una prueba de tamizaje en la detección de alteraciones auditivas en adolescentes usuarios de RPAMC. INTRODUCTION: Frequent use of audio file players and volume intensity are risk factors for the development of hypoacusis. OBJECTIVE: To validate the school-age hearing screening questionnaire (CUTAE, by its Spanish acronym) for hearing disorders detection in teenage users of compressed audio file players (CAFP). METHODS: Adolescent CAFP users without hypoacusis or middle ear pathology were studied. The CUTAE was applied and audiometry was carried out. Reproducibility (intraclass correlation coefficient-ICC), internal consistency (Cronbach's alpha), face validity (Delphi technique), CUTAE-audiometry concurrent validity (Pearson's correlation) and predictive validity (multiple regression) of the questionnaire was assessed. RESULTS: Fifty nine adolescents (118 ears), 66% females, average age of 13 years, were assessed. Ninety ears had normal parameters, 18 showed a threshold decrease < 20 dB, with morphology associated with acoustic trauma (AT) at 6 kHz and 10 with AT. The questionnaire had an ICC of 0.788, a Cronbach alpha-value of 0.807, Pearson's correlation values of 0.290 to 0.368 (p < 0.05); the predictive variables were usage hours, difficulty hearing others (p < 0.05) and type of buzzing (p = 0.07). CONCLUSION: The CUTAE has adequate clinimetric properties to be considered as a screening test in the detection of hearing disorders in adolescent users of CAFP.

Audiometric evaluation short and medium term in cochlear implants.

OBJECTIVE: Our purpose is report the results of cochlear implant program in this Institute, since our first surgery from November 2007, until December 2012. MATERIAL AND METHODS: A cross-sectional study, observational, descriptive, analyzing the information about thresholds before and after implantation, using patients files (diagnosis, onset of hearing loss, brainstem auditory evoked potential (BAEP), computed tomography (CT), magnetic resonance imaging (MRI), implanted ear, brand and model of cochlear implants (CI) and audiometric studies before and after the CI. RESULTS: We report the evolution of 68 patients, age ranged 1 year 8 months to 39 years 3 months old. 94% patients (n = 64) had pre-lingual hearing loss being hereditary non-syndromic hearing loss the most common etiology (29.4%). 100% patients had auditory brainstem responses showing bilateral profound hearing loss, in the 77.9% type A tympanograms were obtained (Jerger's classification), and 100% had absence of stapedial reflexes and otoacoustic emissions with low reproducibility. CT reported as normal in 85.2% of patients, the findings: 5.8% had chronic mastoiditis changes, other findings reported in 1.4% of patients were: digastric right facial nerve, facial nerve canal dehiscence, enlarged vestibular aqueduct, occupation and poor pneumatization of mastoid air cells, lateral semicircular canals agenesis, incomplete partition of the cochlea with wide vestibular and vestibular aqueduct dilatation. Most frequent MR findings of skull with cerebellopontine angle approach were vascular loops of internal auditory canals unilaterally. In 10.2%, 55.8% of patients (n = 38) were implanted in the right ear, 56 (82.3%) with a CI from Advanced Bionics, HiRes 90K model, the remaining with Cochlear, Freedom and Nucleus 5 models. Developments in CI results by audiometric tests: prior to placement was 106.2 dB averages at frequencies assessed, one month later 62.4 dB, at 6 months 44 dB, and with satisfactory threshold 32.9 dB. 55.8% of patients (n = 38) with P + HiRes Fidelity 120 strategy, the remaining with Hires S + Fidelity 120, Hires S and ACE RE. DISCUSSION: Audiology service proposed to place the CI in the worst ear by threshold in audiometric tests, the otolaryngology service proposed the best ear from anatomical point view. Implanted in the INR more Advanced Bionics CI faq frequently due to the donation by the insurance for a new generation. Hearing thresholds using CI have improved since activation.
