Introduction:
Today, due to the increase in the incidence of heart problems in people, we see an increase in the number of heart surgeries worldwide. Hearing disorders in the form of hearing loss have been reported as one of the side effects of this kind of surgery in some studies. Considering the evidence of the effect of open-heart surgery on patients' hearing loss, this systematic review study was conducted to determine the frequency of hearing loss after open-heart surgery.
Methods:
To carry out this systematic review, studies that investigated hearing loss after open-heart surgery in Iran and the rest of world, published in Persian or English, and various international electronic databases including PubMed®, Web of Science, Scopus®, and authentic Persian sources (e.g., Irandoc and Scientific Information Database) until the end of 2021 have been indexed.
Results:
In the initial review, 46 of the 2230 initially searched articles had the conditions for further review. After checking the articles' title and abstract and the working method of the studies and removing duplicates and incomplete articles, a total of 16 articles were included in the study. Then, their results were analyzed as the frequency of hearing loss after open-heart surgery by age and sex.
Conclusion:
The review of various studies confirms the fact that after open-heart surgery, the existence of evidence of hearing changes is not far from expected.
