Abstract
Diabetes mellitus is the second most common chronic disease in childhood which is a metabolic change characterized by the presence of chronic hyperglycemia. Type 1 diabetes is known to be associated with an increased risk of mortality compared with that for the general population. Type 1 diabetes leads to hyperglycemia, which is linked to a number of acute(e.g., diabetic ketoacidosis) and chronic complications (e.g., diabetic nephropathy and cardiovascular disease). Type 1 diabetes is a multifactorial autoimmune disease with both environmental and genetic susceptibility. Otoacoustic emissions (OAEs) are sounds generated in the cochlea by the motility of the outer hair cells. OAEs have become an important tool in the assessment of auditory function, specifically outer hair cells. The sensitivity of OAEs to cochlear damage may allow audiologists to discover auditory impairment before the onset of hearing loss. Auditory Evoked Potentials (AEPs) are brain responses induced by the presence of auditory stimuli. The auditory brainstem response (ABR) is a neurophysiological study that provides functional information about the auditory system and brainstem. Cortical auditory evoked potentials (P1-N1-P2-N2) are obligatory evoked potentials because they are primarily determined by the physical properties of the stimulus. They are affected by both arousal level and attention. Therefore, they should be recorded when the subject is awake and alert. The aim of this work is to evaluate the impact of age, duration of diabetes, and metabolic control on hearing function in type 1 diabetes. To evaluate the whole auditory pathway, with both its cochlear and.
