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.

INTRODUCTION: The Prevalence of Diabetes Melilites Is Increasing All Over the World Particularly in The Developing Countries. Diabetes Is Associated with Hearing Impairment Which Has Been Described as Sensorineural in Origin, But Evidence Favoring a Specific Mechanism Is Insufficient. Brainstem Evoked Response Audiometry Is a Simple, Non-Invasive Procedure to Detect Early Impairment of Acoustic Nerve and Auditory Pathway, Even in The Absence of Specific Symptoms. The Present Study Is Under Taken to Evaluate the Impact of Type 2 Diabetes Mellitus on BERA Parameters. OBJECTIVES: To Analyze and Compare the Brainstem Evoked Response Audiometry in Diabetic Patients and Age and Gender Matched Controls. METHODS: 40 Type 2 Diabetic Patients Attending Outpatient Department of Otorhinolaryngology and Medicine, C. S. S. Hospital, Meerut and 40 Non Diabetic Age and Gender Matched Subjects from General Population Were Selected Randomly, With None of Them Having Complains of Hearing Loss and Were Subjected to Brainstem Evoked Response Audiometry (BERA). BERA Parameters Such as Latency of Wave I, II, III, IV, And V; Inter-Peak Latencies I-III, I-V and III-V Were Analyzed. BERA Parameters Were also assessed according to The Duration of Diabetes and Fasting Blood Glucose Levels. RESULTS: Patients with Type 2 Diabetes Mellitus Were Found to Have Subclinical Hearing Impairment as Revealed by Impaired Auditory Brainstem Response. In This Study Diabetic Patients Showed a Statistically Significant (p value<0.05) Delay in The Latency of Waves I, III and V and Inter-Peak Latency of Waves I-III, I-V and III-V When Compared to Controls. There Was a Positive Correlation Between Prolongation of Latencies and Duration of Diabetes Mellitus. The Latencies Were Also Found to Be Prolonged with altered blood glucose levels. CONCLUSION: The present study correlates with earlier findings that impaired BERA response in diabetic patients is a consequence of microangiopathy. Meticulous control of blood sugar levels is a must to prevent the early complications of diabetes, so that further damage to auditory pathway can be prevented. KEY-WORDS: Diabetes mellitus; Hearing; Brainstem evoked response audiometry (BERA).

AbstractA prospective study of the effect of radiotherapy for nasopharyngeal carcinoma on hearing was carried out on 49 patients who had pure tone, impedance audiometry and auditory brain stem evoked response (ABR) recordings before, immediately, three, six and 12 months after radiotherapy. Fourteen patients complained of intermittent tinnitus after radiotherapy. We found that 11 initially normal ears of nine patients developed a middle ear effusion, three to six months after radiotherapy. There was mixed sensorineural and conductive hearing impairment after radiotherapy. Persistent impairment of ABR was detected immediately after completion of radiotherapy. The waves I–III and I–V interpeak latency intervals were significantly prolonged one year after radiotherapy. The study shows that radiotherapy for nasopharyngeal carcinoma impairs hearing by acting on the middle ear, the cochlea and the brain stem auditory pathway.

<p class="abstract"><strong>Background:</strong> Brainstem evoked response audiometry (BERA) is most specific and sensitive test for brain stem dysfunction. It is most important objective method for evaluating peripheral auditory system in neonates, infants, sedated and comatose patients and other person who doesn’t understand the language. Objective of the study was to evaluate correlation BERA with other audiological tests in different types of hearing loss as well as to study variations of wave forms in different types of hearing loss.</p><p class="abstract"><strong>Methods:</strong> Patients underwent a complete ENT check up to rule out any actively discharging gears, wax, infection or any middle ear problems. Different audiometric tests: pure tone audiometry (PTA), distortion product otoacoustic emissions, auditory steady-state response (ASSR) and BERA were applied to the patients.  </p><p class="abstract"><strong>Results:</strong> The majority of the patients (32 cases) belonged to the age group of 0-5 years. Maximum cases were of sensorineural hearing loss (60%). ASSR was highly sensitive (85.1%) for estimation of hearing threshold and specificity was 100% (p&lt;0.001). BERA was also highly significant for estimation of hearing threshold (sensitivity: 83%; specificity: 92.3%; p value &lt;0.001).</p><p class="abstract"><strong>Conclusions:</strong> BERA has high degree of accuracy in detecting hearing threshold as an objective test but not as much accurate as ASSR. It is more valuable in terms of identification of site and size of the lesion in auditory pathway and identification for the type of the deafness.</p>

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.
