Comparison of Sensorineural Hearing Loss Degree between Controlled and Uncontrolled Type 2 Diabetes Mellitus Patients

Objective: The objective of this study was to determine the degree of sensorineural hearing loss in patients with type 2 diabetes mellitus (T2DM) between good and poor glycemic control. Materials and Methods: This was a cross-sectional study of 70 patients with T2DM who admitted between February and May 2018 at Haji Adam Malik General Hospital. Based on examination of hemoglobin A1c (HbA1c), this study will be divided into two groups, good glycemic control (HbA1c <7) and poor glycemic control (HbA1c ≥7), and each group consists of 35 patients. Routine ear, nose, and throat and pure tone audiometry examination were done to know the degree of sensorineural hearing loss. Results: The results of the study showed that the majority in the controlled group of T2DM had normal hearing thresholds compared with the group of uncontrolled T2DM. There was a significant difference in proportion of the hearing threshold between controlled and uncontrolled T2DM patients in the right ear (P = 0.004) and the threshold on the left ear (P = 0.008). Conclusion: Uncontrolled T2DM patients are more susceptible to hearing loss. Patients with T2DM are advised to better control of blood sugar levels to prevent hearing loss.
