Hearing loss in patients with and without COVID-19 before and alter recovery from positive cases

ABSTRACT

Introduction and objective: There are still few studies on the damage of COVID-19 in hearing, so initial evaluations and their follow-up are recommended, the objective of this study was to compare the degree and type of hearing loss in subjects with and without COVID-19 at the beginning of the disease and after their recovery of whom their positivity was confirmed. Method: prospective, comparative non-experimental study. After signing the informed consent to a voluntary sample of 105 subjects who came to confirm positivity for COVID-19, they underwent tonal audiometry and a reassessment after their recovery of the positives. Results: Sensory superficial hearing loss was more frequent in the group aged 35 to 50 years, in the group negative to SARS-Cov-2, the results before-after the recovery of the positive ones was significant in the average of 7 frequencies and medium frequencies. Discussion: The results of this study coincide with what has been published in relation to the type and degree of hearing loss, age and non-perception of it, the diversity of COVID-19 symptoms without differences between the groups with and without COVID-19. Differences in the averages of pure tones at 7 frequencies and mid-frequencies not reported for contrast. Conclusions: the type and degree of hearing loss was as expected with respect to age, the differences in the averages before and after were better in the second evaluation, probably due to the resolution of the inflammatory condition. It is recommended to increase the sample and add an objective evaluation of the ear half.
