Obesity is a chronic condition, associated with multiple comorbidities. Great attention has been paid to the obesity comorbidities such as cardiovascular disease and insulin resistance up to diabetes mellitus (T2DM), there’s evidence suggests that obesity affects hearing. The aim of the current study was to evaluate the relationship between obesity and hearing in a group of obese children. The present study was a controlled study that was carried out on 80 children of both genders and divided into study group, 40 healthy obese children, they were subdivided after the study has been completed into; group I, 26 healthy obese children with normal middle ear function. Group II 14 obese children with middle ear dysfunction. Control group included forty non- overweight children. Our study revealed that there was significant increase of the pure tone threshold in obese children with middle ear affection in comparison to obese with normal middle ear and the control group. Positive correlation between pure tone with the anthropometric measures, lipid profile and insulin resistance in obese children with diseased middle ear. Cochlear affection in obese children with normal middle ear evidenced by a negative correlation between transient otoacoustic emission with the anthropometry, liver enzymes and insulin resistance. Obesity considered as a risk for conductive hearing loss and cochlear affection.
