ABSTRACT
OBJECTIVE: The objectives of this study were to describe the findings of the auditory screening in children of mothers with ZIKV during pregnancy or suspicious of congenital ZIKV, and to determine whether hearing loss was in the first 2 years in life, regardless of whether microcephaly was also present. METHODS: This is a cases report. The information was collected and recorded in a database between January 2016 and April 2018. We perform two auditory tests to 3 and 24 months of life. The study was developed in Aguachica (Cesar, Colombia). It is considered a high-risk area for ZIKV infection. Participants included children of mothers with confirmed ZIKV during pregnancy or suspicious of congenital ZIKV exposure of ZIKV infection during an epidemic period in a tropical area. We defined a positive case according to the epidemiological definition and clinical criteria based on maternal symptoms. However, other children of mothers without clinical signs of Zika were evaluated at the same time. The main outcome was the presence of sensorineural hearing loss. RESULTS: The median age in the study group (n = 43) was 3.5 months (rank: 0-6) and the comparison group (n: 23, children of mothers without clinical signs of ZIKV) was 3 months (rank: 0-12). Screening hearing test was done using distortion product otoacustic emissions. At 3 months follow-up, children were evaluated using distortion product otoacustic emissions and automatized auditory brainstem response. None of the patients evaluated in this study were found to have sensorineural hearing loss. CONCLUSIONS: We did not find hearing loss during the first 2 years in the children whose mother showed Zika during pregnancy. We recommend these children must be assessed to closed because there is a high risk the hearing loss as it usually may occur with CMV.

Introducción: La cirugía de implante coclear, como cualquier otro acto quirúrgico, puede asociarse a complicaciones inherentes al procedimiento o por un fallo atribuible al dispositivo. Objetivo: Identificar y reportar la tasa de complicaciones asociadas a la implantación coclear en menores de 18 años atendidos en el programa de implante coclear en una institución en Bogotá, Colombia. Diseño: Estudio retrospectivo. Métodos: Se incluyeron pacientes a quienes se les realizaron implantes cocleares pediátricos en el período 1994 al 2011. Se analiza en este estudio a los que recibieron implante coclear a la edad de 18 años o menos. Desenlaces principales: tasa global de complicaciones; tasa discriminada de complicaciones por tipo: médico-quirúrgica, y complicaciones atribuibles a fallo del dispositivo. Resultados: Del total de implantes cocleares (920) realizados durante el período de estudio, se selecciona el grupo con edad ≤ 18 años a la fecha del implante, 598 (65%). Total complicaciones identificadas: 49 (8,2%). Complicaciones médico-quirúrgicas: 15 (2,5%). Fallos relacionados con el dispositivo: 5,7%. Conclusiones: La tasa global de complicaciones y fallos identificada en este estudio se asemeja a la reportada por diferentes estudios, la cual varía entre el 5 y el 13%
Introduction: Cochlear implant surgery, like any surgery, can be associated with complications inherent to the procedure or a failure attributable to the device. Objective: To identify and report the rate of complications associated with cochlear implantation in children under 18 years who presented to the cochlear implant program at a school in Bogota, Colombia. Design: Retrospective. Methods: Patients who underwent pediatric cochlear implants performed in the period 1994-2011. Is analyzed in this study who received cochlear implant at the age of 18 years or less. Main outcome measures: overall complication rate, rate of complications discriminated by type: medical-surgical complications due to device failure. Results: A total of cochlear implants (920) performed during the study period is selected age group ≤ 18 years at the time of implantation, 598 (65%). Total complications identified: 49 (8.2%). Medical-surgical complications: 15 (2.5%). Device-related failures: 5.7%. Conclusions: The overall rate of complications and failures identified in this study is similar to that reported by different studies, which varies between 5 and 13%

Objetivo: presentar la experiencia de una institución en la rehabilitación de pacientes con pérdida auditiva utilizando el implante de oído medio Vibrant Soundbridge® (VSB). Diseño: estudio retrospectivo. Materiales y métodos: se revisaron registros médicos, quirúrgicos y audiológicos de pacientes a los que se les implantó el sistema Vibrant Soundbridge (VSB), evaluando la ganancia auditiva establecida por la diferencia en los promedios de las frecuencias 0.5 a 3 kHz en la audiometría tonal postimplante con el sistema y sin él. Se evaluó también la satisfacción de uso con el dispositivo mediante la encuesta Escala de Satisfacción de Audición con Dispositivo (HDSS, Hearing Device Satisfaction Scale). Realizamos comparación de desenlaces audiológicos con una población de usuarios de similares características del sistema osteointegrado BAHA®. Resultados: 25 pacientes con pérdida auditiva predominantemente mixta recibieron un implante VSB colocando el Transductor de Masa Flotante (FMT) en ventana redonda en 23 casos (92%). La ganancia auditiva promedio fue de 36 ± 16 decibeles (dB). No se identificaron diferencias significativas en la ganancia auditiva entre los procesadores AP404-36 dB y Amadé-38 dB, p = 0.6. La ganancia auditiva en el grupo de usuarios del sistema BAHA fue de 37 dB y la discriminación de lenguaje a 65 dB fue de 93% y 100% para VSB y BAHA® respectivamente. En ambos sistemas el puntaje global de satisfacción fue de 4/5.
Objective: Present the institutional experience on the auditory rehabilitation of patients implanted with the middle ear prosthesis Vibrant Soundbridge®. Design: Retrospective study of a cases series. Materials and Methods: Medical, surgical and audiological charts review of patients implanted with the middle ear system VSB. Hearing gain was established by the mean differences calculated on 0.5 to 3 kHz in the pure tone audiometries pre and post implantation, with and without the device. Satisfaction with the device was assessed with the Hearing Device Satisfaction Scale tool. In addition, audiological and satisfaction comparison with a population with similar characteristics of BAHA implant users was made. Results: 25 patients with conductive and mixed hearing loss were implanted with the VSB, placing the FMT on the round window in 23cases (92%). Mean auditory gain was 36 ± 16 decibels (dB). There were no significance gains between processors AP404-36 dB and Amadé-38 dB, p = 0.6. Mean auditory gain in the BAHA® users was 37 dB; speech discrimination at 65 dB was 93% and 100% for VSB and BAHA® users respectively. Overall satisfaction score for both systems was 4/5. Conclusion: The middle ear implant system VSB gives a satisfactory hearing gain to patients with moderate mixed hearing loss comparable with the BAHA® as well in satisfaction and quality of life issues.
