Abstract

Background: Hearing is one of the most significant senses; There fore, any defect can be frightening. The incidence of sever HEARING LOSS following CORONARY ARTERY BYPASS surgery has been estimated as one per thousand. This Prospective study carried out to determine hearing effects of CORONARY ARTERY BYPASS surgery.Methods: age, AUDIOMETRIC changes before and after surgery (hearing levels at multiple frequencies, speech reception threshold and speech discrimination score), minimum blood pressure during the operation, and the time on bypass, measured on One hundred consecutive patients who candidate for CORONARY ARTERY BYPASS surgery and the results analysed.Results: One hundred patients completed the tests. Based on hearing changes found on pre- and post-operative tests, the patients were divided into 3 groups: Those with no change (47 patients) according to their AUDIOMETRIC results; those with slight changes ≤10 db (43 patients); and those having average deficits of more than 10 db (10 patients). All the patients were male. None of the patients had complete or severe sensorineural HEARING LOSS. The third group had more prolonged pumping duration when compared with the others groups (p=0.002). Furthermore, 90 percent of patients with a sensorineural HEARING LOSS more than 10 db had diabetes mellitus and hyperlipidemia as risk factors. Conclusion: Sudden sensorineural HEARING LOSS is a sequela in patients who undergoing CORONARY ARTERY BYPASS surgery; however, it was usually mild and asymptomatic. Pumping time during the operation is a significant factor in occurring of this complication. With proper treatment of underlying diseases and eliminating the risk factors with improvement of our cardiopulmonary pumps we probably can get better hearing results.
