Early Damage

Platinum chemotherapies are often ototoxic, initially affecting the basal end of the cochlea. Thus, monitoring high-frequency auditory function is advised to reveal early damage. Objective measures of high-frequency auditory function are repeatable over time, but the sensitivity of these measures for monitoring patients receiving platinum derivatives have not been established. We monitored 13 patients across oxaliplatin, carboplatin, or cisplatin treatment using the highest frequencies with responses for each individual. Behavioral thresholds and distortion product otoacoustic emission (DPOAE) gross frequency (f2=16–2 kHz) and concentrated frequency (1/48 octave steps at the highest frequency with a present DPOAE) sweeps were monitored. DPOAE results indicated changes during treatment within individuals using absolute change criteria, as well as statistically significant differences across trial when analyzing group data. Changes varied depending on the drug administered. Behavioral thresholds changed less often than DPOAE measures and when changes were noted, they initially occurred at the highest frequencies monitored. Often, DPOAE changes occurred at frequencies which conventional equipment could not monitor (>8 kHz). Additionally, some changes were characterized by DPOAE level enhancements at conventional frequencies (<8 kHz), while levels at higher frequencies were reduced. Overall, objective high-frequency measures were sensitive to auditory changes in adults undergoing platinum chemotherapy treatment.

AbstractObjectives:This study aimed to: understand the effect that high intensity noise associated with drilling (during otological surgery) has on hearing in the contralateral ear; determine the nature of hearing loss, if any, by establishing whether it is temporary or persistent; and examine the association between hearing loss and various drill parameters.Methods:A prospective clinical study was carried out at a tertiary centre. Thirty patients with unilateral cholesteatoma and normal contralateral hearing were included. Patients were evaluated pre-operatively and for five days following surgery using high frequency pure tone audiometry, and low and high frequency transient evoked and distortion product otoacoustic emission testing.Results:The findings revealed statistically significant changes in distortion product otoacoustic emissions at high frequencies (p = 0.016), and in transient evoked otoacoustic emissions at both low and high frequencies (p = 0.035 and 0.021, respectively). There was a higher statistical association between otoacoustic emission changes and cutting burrs compared with diamond burrs.Conclusion:Drilling during mastoid surgery poses a threat to hearing in the contralateral ear due to noise and vibration conducted transcranially.

Purpose The objective is to describe progressive changes in hearing and cochlear function in children and adolescents treated with platinum-based chemotherapy and to begin preliminary evaluation of the feasibility of extended high-frequency audiometry and distortion product otoacoustic emissions for ototoxicity monitoring in children. Patients and Methods Baseline and serial measurement of conventional pure-tone audiometry (0.5 to 8 kHz) and evoked distortion product otoacoustic emissions (DPOAEs) were conducted for 32 patients age 8 months to 20 years who were treated with cisplatin and/or carboplatin chemotherapy. Seventeen children also had baseline and serial measurement of extended high-frequency (EHF) audiometry (9 to 16 kHz). Audiologic data were analyzed to determine the incidence of ototoxicity using the American Speech-Language-Hearing Association criteria, and the relationships between the different measures of ototoxicity. Results Of the 32 children, 20 (62.5%) acquired bilateral ototoxicity in the conventional frequency range during chemotherapy treatment, and 26 (81.3%) had bilateral decreases in DPOAE amplitudes and dynamic range. Of the 17 children with EHF audiometry results, 16 (94.1%) had bilateral ototoxicity in the EHF range. Pilot data suggest that EHF thresholds and DPOAEs show ototoxic changes before hearing loss is detected by conventional audiometry. Conclusion EHF audiometry and DPOAEs have the potential to reveal earlier changes in auditory function than conventional frequency audiometry during platinum chemotherapy in children.

Objective: The objective of this study was to investigate the role of the high-frequency cochlear dysfunction in the cognitive-ear link.Methods: Seventy-four presbycusis patients (PC group) and seventy-one age-, sex-, and education-level matched normal hearing controls (NH group) were recruited in this study. Participants underwent a battery of cognitive tests estimated by Montreal Cognitive Assessment (MoCA), Stroop Color-Word Interference Test (Stroop), Symbol Digit Modalities Test (SDMT), Auditory Verbal Learning Test (AVLT), and Trail-Making Test (TMT-A and B), as well as auditory tests including distortion product otoacoustic emission (DPOAE), pure tone (PT) thresholds, and speech reception thresholds (SRT). Data were analyzed using the factor analysis, partial correlation analysis, multiple linear regression models, and mediation models.Results: Distortion product otoacoustic emission detection amplitudes and PT thresholds performed worse gradually from low to high frequencies in both the NH and PC groups. High-frequency DPOAE (H-DPOAE) was significantly correlated with cognitive domains in the PC group (AVLT: r = 0.30, p = 0.04; SDMT: r = 0.36, p = 0.01; Stroop: r = –0.32, p = 0.03; TMT-A: r = –0.40, p = 0.005; TMT-B: r = –0.34, p = 0.02). Multiple linear regression models showed that H-DPOAE predicted cognitive impairment effectively for aspects of memory (R2 = 0.27, 95% CI, 0.03 to 1.55), attention (R2 = 0.32, 95% CI, –6.18 to –0.40), processing speed (R2 = 0.37, 95% CI, 0.20 to 1.64), and executive function (TMT-A: R2 = 0.34, 95% CI, –5.52 to 1.03; TMT-B: R2 = 0.29, 95% CI, –11.30 to –1.12). H-DPOAE directly affected cognition and fully mediated the relationship between pure tone average (PTA)/SRT and cognitive test scores, excluding MoCA.Conclusion: This study has demonstrated that the high-frequency cochlear amplifier dysfunction has a direct predictive effect on the cognitive decline and makes a large contribution to the cognitive-ear link.

This study examined the association between ultrahigh-frequency (UHF) hearing sensitivity and distortion-product otoacoustic emission (DPOAE) levels at conventional frequencies. Behavioral thresholds were measured from 2 through 16 kHz, and DPOAE levels were measured at discrete f2 frequencies between 2 through 8 kHz in 553 young normal-hearing adult male participants. A DPOAE frequency sweep was measured with primary stimulus levels of L1/L2 = 65/55 dB SPL and an f2/f1 of 1.2. Significant negative correlations, although weak, were found between UHF behavioral thresholds and DPOAE levels. As UHF behavioral thresholds worsened, DPOAE levels decreased at all frequencies. When the data were categorized into two groups, “better” and “worse” UHF behavioral thresholds, significant differences were apparent between the two groups for DPOAEs. Additionally, those with better UHF thresholds had better conventional thresholds compared to those in the worse UHF threshold group. The results of this age-restricted, large-sample-size study confirm and augment findings from earlier studies demonstrating that UHF hearing sensitivity has some influence on DPOAE measures at frequencies from 2 through 8 kHz with moderate stimulus levels. However, because those with better UHF thresholds also had better conventional thresholds and the significant correlations found were weak, this work supports the importance of UHF hearing testing in conjunction with otoacoustic emission measures to identify basal cochlear insults not evident from behavioral testing at conventional frequencies. Este estudio examinó la asociación entre la sensibilidad auditiva a ultra-alta frecuencia (UHF) y los niveles de las emisiones otoacústicas por productos de distorsión (DPOAE) en las frecuencias convencionales. Se midieron los umbrales conductuales desde 2 y hasta 16 kHz, y los niveles de la DPOAE se midieron a frecuencias discretas f2 entre 2 y 8 kHz en 553 adultos jóvenes masculinos oyentes normales. Se registró un barrido frecuencial de DPOAE con niveles primarios de estímulo de L1/L2 = 65/55 dB SPL y un f1/f2 de 1.2. Se encontraron correlaciones negativas significativas, aunque débiles, entre los umbrales conductuales de UHF y los niveles de las DPOAE. Conforme los umbrales conductuales de UHF se deterioraron, los niveles de DPOAE disminuyeron en todas las frecuencias. Cuando los datos se categorizaron en dos grupos – umbrales conductuales de UHF “mejores” y “peores” – se hicieron aparentes diferencias significativas entre los dos grupos para las DPOAE. Adicionalmente, aquellos con los mejores umbrales UHF tuvieron mejores umbrales convencionales, comparados con aquellos en el grupo de los peores umbrales UHF. Los resultados de este estudio con restricción de edad y con una muestra de gran tamaño confirman y destacan los hallazgos de estudio anteriores que demostraban que la sensibilidad auditiva en UHF tiene alguna influencia sobre las mediciones de las DPOAE, en las frecuencias de 2 a 8 kHz, con niveles moderados de estímulo. Sin embargo, dado que aquellos con mejores umbrales UHF también tenían mejores umbrales convencionales y que la correlación significativa encontrada era débil, este trabajo apoya la importancia de la evaluación de la audición en UHF en conjunto con mediciones de emisiones otoacústicas para identificar insultos cocleares basales, no evidentes en la evaluación conductual en frecuencias convencionales.
