Evoked Response Audiometry

A group of guinea pigs was rendered hypothyroid using propylthiouracil solution in their drinking water. The animals were hypothyroid for at least 120 days. During this time no change was noted in their hearing thresholds for high-frequency clicks. The audiometric evaluation was performed using brainstem evoked response audiometry.

Evoked Response Audiometry

Objectives: To find out the incidence of hearing impairment in Neonatal Intensive Care Unit (NICU)-admitted newborns and to correlate between several risk factors. Design: Prospective observational study. Setting: In a tertiary teaching hospital of Odisha between October 2014 and October 2016. Study population: 100 newborns delivered in the institution and admitted in NICU with usual indications and risk factors that underwent otoacoustic emission 1 and 2 (OAE1, OAE2) and Brainstem Evoked Response Audiometry (BERA). Results: 84 babies in OAE1 and 86 babies in OAE2 got “pass” results. In BERA test, 92 babies got normal waveform. 7 (13.7%) of 51 premature babies, 5 (38.5%) of 13 very low birth weight babies, 7 (17.5%) of 40 babies receiving ototoxic medication for >5 days, 7 (31.8%) of 22 babies with hyperbilirubinemia, 6 (42.9%) of 14 babies with sepsis, 5 (20%) of 20 babies with birth asphyxia, 3 (60%) of 5 babies under mechanical ventilation for >5 days, 1 baby with ear abnormality, and 1 (50%) out of 2 babies with congenital infections had hearing impairment and statistically significant association with abnormal OAE and BERA test. Conclusion: There is high incidence of hearing loss in NICU-admitted newborns. OAE and BERA both should be performed for complete evaluation of hearing. Important risk factors are elaborated. Predischarge hearing assessment in NICU is most important.

OBJETIVO: Estudar comparativamente a habilidade de reconhecimento de fala no silêncio e na presença de ruído competitivo em crianças usuárias de implante coclear utilizando dois diferentes processadores de fala. MÉTODOS: Foram avaliadas 26 crianças usuárias do implante coclear Nucleus 24M/24K, da Cochlear Corporation®, divididas em dois grupos de acordo com o processador de fala utilizado. O Grupo 1 foi composto por 16 crianças que faziam uso do processador de fala Sprint e o Grupo 2 foi composto por 10 crianças que faziam uso do processador de fala Freedom. Foi aplicado o Hearing in Noise Test - versão em Português/Brasil, em campo livre, na condição de silêncio e na presença de ruído competitivo. RESULTADOS: O desempenho do Grupo 2 (Freedom) foi superior ao desempenho do Grupo 1 (Sprint) em todas as condições de avaliação, sendo evidenciada diferença entre eles na condição de silêncio. CONCLUSÃO: O processador de fala apresentou influência significativa na percepção de fala de crianças usuárias dos implantes cocleares Nucleus 24K e 24M. As características de pré-processamento do som presentes no processador de fala Freedom podem ter contribuído para o melhor desempenho do Grupo 2 nos testes de percepção de fala realizados. Novos estudos são necessários para complementação destes achados.

Evoked Response Audiometry

Introduction Diabetes has become a global epidemic. Hearing loss has been long associated with diabetes. Brainstem Evoked Response Audiometry (BERA) is an objective, non-invasive, electro diagnostic test that not only evaluates the functional integrity of the subcortical auditory pathway but also provides topo-diagnosis of hearing loss. This study aims to identify the role BERA in detecting hearing loss early in diabetic patients.Materials and Methods In this study a total of 210 patients were taken and subjected to blood glucose levels followed by PTA were divided into two groups. Group I (n=105) consisted of diabetic patients with sensorineural hearing loss (SNHL) and Group II (n=105) had age and sex matched non-diabetics with SNHL. All the patients were evaluated with BERA.Results All the patients were subjected to Brain Stem Evoked Response Audiometry (BERA). Absolute latency of Wave I, III, V, I-III, III-V and I-V were assessed for both the ears. In both ear Absolute latency were significantly higher in diabetics as compared to non-diabetic patientsConclusion The findings of present study showed that the severity of hearing loss was significantly higher in diabetic patients as compared to non-diabetic controls. Level of glycemic control showed a possible link with severity of hearing loss.
