Background: A growing amount of evidence suggests that individuals infected with the coronavirus disease 2019 (COVID-19) are susceptible to sudden sensorineural hearing loss (SSNHL). Unknown is the connection between COVID-19 and the pathophysiology of SSNHL. The aim of this study was to correlate the SSNHL to Covid-19 positive PCR patients.
Results: According to Distribution of patients according to SNHL severity, 54 (27%) patients were mild, 23 (11.5%) Mild to moderate, 61 (30.5%) moderate, 14 (7%) Moderate to severe, 13 (6.5%) severe, 26 (13.5%) Severe to profound and 9 (4.5%) profound. 193 (96.5%) of patients suffered from unilateral SNHL. Regarding Associated Audio-vestibular Signs and symptoms, 134 (67%) suffered from Tinnitus, 19 (9.5%) from Vertigo, 13 (6.5%) from Dizziness, 8 (4%) from Ear pain and 3 (1.5%) Facial nerve palsy. 110 (55%) of patients were treated by Systemic steroids, 29 (14.5%) by Local steroids, 27 (13.5%) by Combined local and systemic steroids and 34 (17%) by other treatment (contraindicated to steroids). SNHL prognosis, patients who received Combined Local and systemic steroids was with the best prognosis. There was a statistically significant difference in patients' prognosis according to type of treatment.
Conclusion: The audiovestibular system can be affected by SARS-COV-2 resulting in sudden sensorineural hearing loss (SSNHL) which can be reversible by combined local and systemic steroid therapy with good prognosis.
