Estudo da prevalência de hipoacusia em indivíduos com diabetes mellitus tipo 1

Abstract

Diabetes mellitus (DM) is a chronic degenerative disease that impairs normal insulin production and use. DM chronic auditory complications may include spiral ganglion atrophy, degeneration of the vestibulocochlear nerve myelin sheath, reduction of the number of spiral lamina nerve fibers, and thickening of the capillary walls of the stria vascularis and small arteries. Objective This paper aims to verify the hearing thresholds of individuals with type 1 DM. Materials and Methods Sixty patients were enrolled in this trial and divided into case and control groups featuring diabetic and non-diabetic subjects respectively. All individuals were interviewed and underwent physical examination, ENT examination, and audiometric tests. Results Statistically significant difference was observed in hearing thresholds of case group subjects at 250, 500, 10,000, 11,200, 12,500, 14,000 and 16,000 Hz for both ears and ear average. Case group subjects had higher likelihood of having hypacusis at any frequency regardless of ear than controls. Conclusion Statistically significant differences were seen in the audiological findings of case group subjects when compared to controls. Thorough audiological examination including high frequency audiometry is required for subjects with diabetes mellitus type 1.

The risk factors of hearing loss in diabetes mellitus

“…In a study Taziki et al have reported that hearing impairment in people with diabetes is three times more than the general population [7]. Malucelli et al also reported the same findings [5]. Conversely, Salvinelli [8] and Sieger [9] could not find a significant relationship between diabetes and hearing impairment.…”

“…The prevalence of diabetes was estimated to be 140 million at the end of the twentieth century and it is predicted that this figure will reach 300 million in 2025 [3]. Complications associated with diabetes such as blindness, nephropathy, neuropathy and nontraumatic amputation have key roles in endangering public health and increasing the economic burden for the countries [4,5].…”

Construction and validation of nursing diagnoses for individuals with diabetes in specialized care

“…Impaired hearing in clinical practice among individuals with diabetes is not a common element, which has led to controversies regarding its causality in the specialist literature. While these limits are considered in the cause and effect relationship between diabetes and loss of hearing, the study highlights symptoms such as fluctuating hypoacusis, sensory hearing impairment, tinnitus and sensation of auricular plenitude and suggests the inclusion of a complete audiological evaluation in type 1 diabetic patients (18) . Diminished sensitivity occurs predominantly in the lower limbs, as a consequence of the complications of the diabetic neuropathy, affects the quality of life of the individuals with diabetes and represents a potential risk of development of ulcerated lesions on the feet and deformations, which are important aspects at the time of assessment of the feet (12) .…”

High-Frequency Audiometry in Women with and without Exposure to Workplace Noise

“…High-frequency audiometry has been studied for several decades, but the lack of commercially available equipment and the standardization of calibration recommendations have long limited its use [ 3 , 4 , 5 ]. At present, high-frequency audiometry is performed according to the currently valid standard: IEC 60645-1 Electroacoustics—Audiometric equipment—Part 1.…”
