RESUMO

Introducción El umbral de confort máximo o maximum comfort level (MCL), umbral eléctrico o threshold level (THR) e impedancia eléctrica cambian en el postoperatorio del implante coclear durante meses hasta estabilizarse. El objetivo de este artículo es establecer la variación durante cinco años posquirúrgicos de la impedancia, y su relación con MCL en adultos implantados unilateralmente. Métodos Estudio retrospectivo a cinco años, con 78 pacientes adultos implantados con MED-EL en un hospital terciario desde el año 2000 hasta 2015. Se analizó la variación de impedancia, MCL y relación entre ellos, en electrodos basales (9-12), medios (5-8) y apicales (1-4), realizando análisis inferencial ANOVA de medidas repetidas con comparaciones entre tiempos consecutivos, corregidas con criterio Bonferroni. Resultados Treinta y tres hombres (42,3%) y 45 mujeres (57,7%), con edad media 52,7 ± 14,6 años. Se consideró «estabilidad» el momento del seguimiento sin diferencias estadísticamente significativas entre una visita y la siguiente. Los cambios en la impedancia en electrodos medios dejaron de ser estadísticamente significativos a los tres meses, y en apicales a los seis meses, con valores medios de 5,84 y 6,43 kohms. MCL se estabilizó a los dos años en electrodos basales y apicales, y a los tres años en medios, con valores medios de 24,9, 22,7 y 25,6 qu. Hubo correlación entre MCL e impedancia en electrodos medios hasta 3 meses y en apicales hasta un año. Conclusiones La impedancia eléctrica desciende significativamente en electrodos medios y apicales hasta tres y seis meses. El MCL aumenta significativamente hasta dos años. La impedancia se relaciona con MCL hasta seis meses. (AU)

RESUMO

INTRODUCTION: The maximum comfort level (MCL), threshold level (THR) and electrical impedance change in the postoperative period of the cochlear implant for months until they stabilize. The objective of this article is to establish the variation during 5 post-surgical years of impedance, and its relationship with MCL in unilaterally implanted adults. METHODS: Retrospective study over 5 years, with 78 adult patients implanted with MED-EL in a tertiary hospital from the year 2000 to 2015. The variation in impedance, MCL and the relationship between them were analyzed in basal (9-12), medial (5-8) and apical electrodes (1-4), performing an inferential ANOVA analysis of repeated measures with comparisons between consecutive times, corrected with Bonferroni criteria. RESULTS: 33 men (42.3%) and 45 women (57.7%), with a mean age of 52.7±14.6 years. "Stability" was considered the time of follow-up without statistically significant differences between one visit and the next. Changes in impedance in medial electrodes ceased to be statistically significant at 3 months, and in apicals at 6 months, with mean values of 5.84 and 6.43kΩ. MCL stabilized at 2 years in basal and apical electrodes, and at 3 years in medial, with mean values of 24.9, 22.7, and 25.6qu. There was a correlation between MCL and impedance in medium electrodes up to 3 months and in apical ones up to one year. CONCLUSIONS: Electrical impedance drops significantly in medial and apical electrodes up to 3 and 6 months. MCL increases significantly up to two years. Impedance is related to MCL up to 6 months.

RESUMO

OBJECTIVE: Evaluation of a new active osseointegrated bone-conduction hearing implant in moderate to severe mixed-hearing loss. STUDY DESIGN: Prospective observational study of a series of cases. SETTING: Tertial referral center. PATIENTS: Twenty patients with moderate mixed-hearing loss were evaluated (10 Cochlear Osia group and 10 Baha 5 Power Connect -control group). INTERVENTION: Rehabilitative. MAIN OUTCOME MEASURES: Hearing performance in quiet and in noise and quality-of-life were evaluated. RESULTS: Improvements in audibility, speech-understanding, speech-recognition, and quality-of-sound in noise and quiet were found for the Osia System compared with preoperative unaided hearing and performance was similar to that obtained with Baha 5 Power Connect. CONCLUSIONS: The new active transcutaneous bone conduction system provided a tonal improvement in free-field at middle and high frequencies. The performance in speech recognition in quiet and in noise was similar to control group outcomes.

RESUMO

Los dispositivos auditivos osteointegrados (DAO) Power y SuperPower presentan indicaciones para umbrales en vía ósea de 55 y 65dB, respectivamente. Realizamos un estudio observacional prospectivo de una serie de 6 casos con hipoacusia mixta en los que se realizó implantación del DAO Ponto(TM) SuperPower. Se realizaron previo a la implantación y 6 meses tras la adaptación valoraciones tonales y verbales sin y con ruido de fondo (HINTS). Todos los participantes mostraron mejoría en los resultados tonales y verbales, variando según el grado de hipoacusia contralateral. Cabe destacar los resultados verbales con ruido de fondo donde la mayoría de los pacientes obtuvieron una relación señal ruido entre 2 y 4 dB. Los resultados en los cuestionarios APHAB y GBI mostraron una reducción de la percepción del problema y una mejoría en la calidad de vida, respectivamente. Los resultados presentados reflejan la posibilidad de tratamiento de hipoacusias mixtas con el dispositivo DAO Ponto(TM) SuperPower


Osseointegrated hearing devices Power and SuperPower present indications for bone thresholds of 55 and 65 dB respectively. We conducted a prospective observational study of a series of six cases with mixed hearing loss for whom implantation of the DAO Ponto(TM) Super-Power was performed. Tonal and verbal evaluations without and with background noise (HINTS) were performed prior to implantation and six months after adaptation. All the participants showed improvement in tonal and verbal results, varying according to the degree of contralateral hearing loss. The verbal results with background noise were noteworthy, where most of the patients obtained a signal-to-noise ratio between 2 and 4 dB. The results in the APHAB and GBI questionnaires showed a reduction in the perception of the problem and an improvement in quality of life respectively. The results presented reflect the possibility of treatment of mixed hearing loss with the Ponto(TM) SuperPower device

RESUMO

OBJECTIVE/HYPOTHESIS: To investigate outcomes including efficacy, quality of life, and levels of inflammatory markers of a mandibular advancement device (MAD) for moderate-to-severe obstructive sleep apnea (OSA). STUDY DESIGN: Case-control study. METHODS: Patients with apnea-hypopnea index (AHI) ≥ 15/hr who only accepted MAD therapy (study group) or who refused any treatment (control group) were recruited. At baseline and at 6 months, polysomnography, Epworth Sleepiness Scale (ESS), Functional Outcomes of Sleep Questionnaire (FOSQ), C-reactive protein (CRP), interleukin 1ß, interleukin 6, and tumor necrosis factor α (TNF-α) were assessed in both groups. RESULTS: At baseline, the study group (n = 30) showed a higher percentage of rapid eye movement sleep and higher CRP levels (P < .05) than the control group (n = 10). At 6 months, the MAD significantly improved AHI and lowest oxygen saturation (P < .01), non-rapid eye movement (N)1 and N3 sleep stages (P < .05), ESS score (P < .05), FOSQ total score (P < .01), interleukin 1ß (P < .05), and TNF-α (P < .01) compared with the untreated group. In the overall, moderate, and severe OSA groups, 63.3%, 75%, and 50%, respectively, achieved at least good response. CONCLUSIONS: Use of a MAD significantly improved polysomnographic parameters, quality of life, and some inflammatory markers (CRP, IL-ß, and TNF-α) in a significant proportion of patients with moderate OSA and in some patients with severe OSA. Hence, a MAD may be a viable alternative therapy in patients with moderate-to-severe OSA who refuse continuous positive airway pressure. LEVEL OF EVIDENCE: 3b. Laryngoscope, 128:1720-1726, 2018.

RESUMO

Se incluyeron en el estudio 9 pacientes implantados con el dispositivo Baha(R) Attract. A todos los pacientes se les realizó, con y sin el dispositivo, una audiometría tonal en campo libre, una audiometría verbal en campo libre, y una audiometría verbal con ruido de fondo, así como la aplicación de los cuestionarios Glasgow Benefit Inventory (GBI) y Abbreviated Profile of Hearing Aid Benefit (APHAB). Las valoraciones audiológicas con el dispositivo mostraron unos umbrales auditivos promedios de 35,8 dB, con ganancias medias de 25,8 dB. El umbral de recepción verbal promedio con el dispositivo se situó en 37 dB, mostrando una ganancia de 23 dB. Los resultados promedio del umbral de discriminación máxima fueron de 60 dB con el dispositivo. El Baha(R) Attract logra alcanzar unas ganancias auditivas en los pacientes indicados correctamente, con una consiguiente valoración subjetiva positiva por parte de los pacientes, presentando no obstante un efecto atenuativo en su transmisión transcutánea, que le impide alcanzar mayores ganancias (AU)


We included 9 patients implanted with Baha(R) Attract. All our patients were evaluated by free field tonal audiometry, free field verbal audiometry and free field verbal audiometry with background noise, all the tests were performed with and without the device. To evaluate the subjective component of the implantation, we used the Glasgow Benefit Inventory (GBI) and Abbreviated Profile of Hearing Aid Benefit (APHAB). The auditive assessment with the device showed average auditive thresholds of 35.8 dB with improvements of 25.8 dB over the previous situation. Speech reception thresholds were 37 dB with Baha(R) Attract, showing improvements of 23 dB. Maximum discrimination thresholds showed an average gain of 60 dB with the device. Baha (R). Attract achieves auditive improvements in patients for whom it is correctly indicated, with a consequent positive subjective evaluation. This study shows the attenuation effect in transcutaneous transmission, that prevents the device achieving greater improvements (AU)

RESUMO

Introducción. Las crisis de hipo suelen ser autolimitadas y benignas, pero los episodios prolongados alteran la calidad de vida y requieren asistencia, ya que existen causas identificables que el otorrinolaringólogo debe conocer para su diagnóstico y tratamiento. Su manifestación última es un ruido glótico espasmódico con alteraciones cervicales características. Pacientes y métodos. Desde 1979 se revisaron todos los casos que consultaron por hipo persistente o recidivante, anotando cronobiología, patología concomitante, resultados de las exploraciones, tratamiento y respuestas al mismo. Resultados. Se asistieron 37 pacientes con una edad media de 45,5±13,5 años, de los cuales 30 eran varones; 23 pacientes (el 62%) presentaron hipo persistente. En 24 casos (el 65%) se evidenció una causa potencialmente asociable: enfermedades del esófago en 14 —la mayoría reflujo gastroesofágico— y en 8 se apreció o descubrió patología oncológica concomitante. Solo 3 casos fueron intervenidos como resultado de los hallazgos efectuados. Los protocolos de tratamiento incluyeron metoclopramida en 18 sujetos, clorpromazina en 17 y baclofeno en 13, pero también carbamazepina o haloperidol. Se empleó neuroestimulación del nervio frénico en 6 pacientes. El hipo desapareció en 32 casos. De los 22 sujetos en los que se pudo efectuar seguimiento, se constató recidiva en 5 —precisando por ello nuevas terapias— y 11 fallecieron. Conclusiones. El hipo crónico implica un reto multidisciplinar con potencial afectación en cabeza y cuello, una sistemática diagnóstica de descarte, frecuente patología de base esofágica y una incidencia de neoplasia maligna alta. Los agentes procinéticos y neurolépticos con efecto antidopaminérgico y anticolinérgico suponen la base del tratamiento (AU)


Introduction. Hiccup crises are generally benign and self-limiting, but longer episodes affect quality of life and must be treated. There are recognisable causes that otorhinolaryngologists must know and be aware for diagnosis and therapeutic alternatives. The main expression is a spasmodic glottic noise with characteristic neck alterations. Patients and methods. This was a retrospective study from 1979 with patients suffering persistent or recurrent hiccups. Chronobiology, comorbidity, findings from explorations, therapies and outcomes were noted. Thirty-seven patients were studied (mean age, 45.5±13.5 years; 30 males), with persistent hiccups in 23 (62%). Results. A potential associated aetiology was observed in 24 cases (65%): oesophageal disorders —mainly gastroesophageal reflux— were detected in 14 cases and concomitant oncological disease was found in 8. Only 3 cases were admitted for surgery due to these findings. Therapeutic strategies with metoclopramide were used in 18 subjects, chlorpromazine in 17 and baclofen in 13, while carbamazepine or haloperidol were used in a minority. Phrenic nerve stimulation was employed in 6 patients. Hiccups disappeared in 32 cases. Out of 22 cases for which follow-up was possible, the hiccups recurred in 5 subjects (the subjects requiring new therapies) and 11 patients died. Conclusions. Chronic hiccup represents a multidisciplinary challenge that includes potential head and neck affection, a diagnostic schedule for ruling out causes, frequent base oesophageal alterations and high incidence of malignant neoplasm. Prokinetic and neuroleptic agents with antidopaminergic and anticholinergic effects are the pillars of its treatment (AU)

RESUMO

Introducción y objetivos: La prueba calórica es hasta ahora la prueba de referencia para el diagnóstico y el examen de una hipofunción vestibular unilateral. El video head impulse test (vHIT) valora el reflejo vestíbulo-oculomotor, mediante el registro videoasistido de la maniobra impulsiva. Se pretende comparar la variación de los resultados del vHIT y la prueba calórica en pacientes con neuritis vestibular respecto a su estado inicial en diferentes puntos de su evolución, y comprobar su grado de correlación entre sí y con el test Dizziness Handicap Inventory (DHI). Métodos: Exploración en la misma sesión mediante vHIT y prueba calórica de 20 pacientes con neuritis vestibular. Valoración de la correlación de dichas pruebas entre sí y con el test DHI en 2 momentos diferentes de la evolución para cada paciente. Resultados: La asimetría de la ganancia del vHIT y la paresia canalicular de la prueba calórica no evidenciaron una correlación lineal entre ellas. Tampoco se apreció una correlación entre el DHI y la recuperación de los parámetros de estas 2 pruebas. Las sacadas Covert mantienen una velocidad similar mientras están presentes en el vHIT, mientras que las Overt disminuyen su velocidad con el tiempo. Conclusiones: El vHIT y la prueba calórica muestran diferentes respuestas del reflejo vestíbulo-oculomotor, dado que exploran diferentes frecuencias del mismo. No se ha encontrado una correlación entre el vHIT, la prueba calórica y el DHI a lo largo de la evolución de la neuritis vestibular, siendo pruebas complementarias entre sí (AU)


Introduction and objectives: The caloric test is the gold standard for the loss of vestibular function diagnosis. The Video Head Impulse Test (vHIT) assesses the same reflex by using a video- assisted examination of the impulsive maneuver. We intend to compare the variation of results of the vHIT and the caloric test in patients with vestibular neuritis with respect to their initial condition at two different moments of their evolution and to check the level of correlation between them and with that of the DHI test. Methods: We explored 20 patients with neuritis by using both vHIT and the caloric test on the same day. We assessed the correlation between these two tests and with the DHI test for each patient at two different moments of their evolution. Results: We calculated gain asymmetry and compared it with the canal paresis, but we found neither a linear correlation between them, nor a correlation between the DHI test or improvement of these two other tests. We conclude that the covert saccades maintain a similar speed whilst present in the VHIT, but the overts diminish their speed over time. Conclusions: The VHIT and the caloric test show different responses of the vestibulo-ocular reflex, because they stimulate different frequencies of this reflex. No correlation was found between the VHIT, the caloric test and the DHI test. The tests appear to complement one another (AU)
