“…Other studies also came up with similar results. 11,19,26 Dalton et al found weak association between NIDDM and hearing loss, but at same time also stating that auditory symptoms were more common in patients with NIDDM and nephropathy as compared to those with NIDDM and no nephropathy. 27…”

“…that diabetes mellitus has a negative effect on hearing; the prevalence varying from 13.1% (according to Kakarlapudi, USA) to 60% (according to Pathak et al). 10,11 The pathogenesis of hearing loss in Diabetes has been explained on the basis of mitochondrial DNA mutation, neuropathy, and microangiopathy. 12 Given this scenario of increasing incidence of preventable hearing loss and the indefinite results of association between diabetes and hearing loss, present study aims to explore the linkage between hearing loss and diabetes mellitus, and certain factors associated with it like, glycemic control, presence of diabetes related complications, serum creatinine, and serum cholesterol.…”

Background: The association between Hearing loss and diabetes, first mentioned by Jardao in 1857, had been under continuous research since then; giving both positive and negative results. This study aims to explore the relationship of hearing loss with type II DM and also to evaluate the impact of glycemic control over degree of hearing loss. Methods: 92 patients with type II DM were enrolled in this study, audiometrically evaluated and compared with equal number of age and sex matched non-diabetic controls. Apart from audiological tests, haematological tests like FBS, PPBS, HbA1c, serum creatinine and cholesterol were carried out to assess glycemic control. Results: It was observed that 31 (34%) of the diabetic patients had mild to moderate sensorineural hearing loss, while only 12 (13%) of the control group suffered from the same, which is statistically significant (p<0.05). Among these 31 patients, 19 (61%) patients had uncontrolled diabetes (HbA1c >8.5) and 12 (39%) had higher creatinine levels (>2.5 mg/dl). Higher frequencies (4 and 8 kHz) were found to be affected more, both in case and control groups. Low stapedial reflex thresholds were observed in 14% patients of case group and 5.4% of the controls. Speech discrimination scores were not significantly different. Otoacoustic emission showed outer hair cell dysfunction in 85% cases and 66% controls. Conclusions: There is a strong correlation between diabetes mellitus and hearing threshold levels especially at higher frequencies. Long duration and uncontrolled diabetes has more implications over hearing threshold. Since the pattern of hearing loss in diabetes and presbycusis is similar, it may be said that hearing level with ageing is significantly impaired earlier in diabetic patients as compared to general population.

“…1 The usual pattern of hearing loss in diabetes is progressive, bilateral sensorineural hearing loss (SNHL) affecting higher frequencies. 2 The proposed mechanisms leading to hearing loss in diabetes mellitus are microangiopathy of the inner ear, neuropathy of the cochlear nerve, dysfunction of outer hair cell, and disruption of endolymphatic potential. 3,4 Pure tone audiometry (PTA) is an important hearing test which determines the hearing threshold levels in an individual.…”

Introduction: The association of hearing loss and diabetes has been under research for many years. The hearing loss in diabetes in our population has not been studied extensively. The objective of this study was to compare the hearing threshold between type 2 diabetic patients and age- and sexmatched controls. Materials and Methods: A comparative study was done in the Department of ENT, Kathmandu Medical College from October 2019 to February 2020. The hearing threshold, of 40 type 2 diabetics patients, and 40 age- and sex-matched healthy controls in the age group of 35 to 55 years, were assessed by pure tone audiometry. The hearing threshold was compared between the two groups by using the student’s unpaired t-test. Results: Among 40 diabetes patients, 29 (72.5 %) had bilateral, mild to moderate sensorineural hearing loss. The hearing threshold in diabetes patients was signifi cantly higher than the healthy controls in all the frequencies except at 250 Hz. When comparing the threshold according to the duration of diabetes, it was found to be signifi cantly higher only at higher frequencies (4000 and 8000 Hz) in diabetes with more than 5 years duration. Conclusions: The hearing loss was common in type 2 diabetes mellitus. Most diabetic patients had mostly bilateral mild to moderate sensorineural hearing loss affecting hearing thresholds in higher frequencies than the healthy controls as assessed by pure tone audiometry.

“…The relationship between sensorineural hearing loss and diabetes mellitus is still controversial 11 but recent studies have shown a positive correlation between the two. 8,11,12 This correlation is established based on the neuropathic and angiopathic abnormalities that often accompany diabetes mellitus. It is speculated that the vascular and neuronal changes occurring as a result of diabetes mellitus could lead to the thickening of the basal membrane of the capillaries of stria vascularis, demyelination of the nerve of the cochlea and atrophy of spiral ganglion; all of which, alone or in combination, would lead to hearing loss.…”

“…1,6,7 Diabetes mellitus is a metabolic disorder due to relative or absolute lack of insulin resulting in elevated blood glucose levels associated with long term vascular and neurological complications. 7,8 There are 2 types of diabetes mellitus; type 1 and type 2. In type 1 diabetes there is inadequate synthesis of insulin by the pancreas while in type 2 diabetes the sensitivity of cells to insulin is decreased.…”

Objective: To determine the magnitude and effects of diabetes mellitus in patients of sudden sensorineural hearing loss and on the final outcome of therapy. Study Design: Cross sectional study. Place and Duration of Study: ENT unit of Medical Teaching Institution Abbottabad, from Jul 2018 to Jun 2020. Methodology: A total of 84 patients presented who had idiopathic sudden sensorineural hearing loss by using non probability consecutive sampling enrolled in the study. Basic parameters, age, diabetes mellitus and hearing loss were used for data collection. The data was analyzed by using SPSS version 23. Results: Out of total 52 (61.9%) were male and 32 (38.1%) were female, mean age was 45.62 ± 14.12 years from 14-85 years. A large number of patients presented within one week of onset of hearing loss 57 (67.86%). In our patient group 18 patients (21.4%) had diabetes mellitus and 66 patients (78.6%) did not have diabetes mellitus at presentation. Initial Hearing loss at presentation was significantly more in patients who had diabetes mellitus p=0.006 and there was statistically strong association between the final hearing improvement and diabetes mellitus p<0.001. Conclusion: Diabetes mellitus is associated with more severe hearing loss at initial presentation and poorer final outcome in patients with Idiopathic sudden sensorineural hearing loss. As glycemic control does not affect the result so corticosteroid therapy must be given to all patients of sudden sensorineural hearing loss with diabetes mellitus.
