Abstract
Coronaviruses are large enveloped RNA viruses that cause mild respiratory diseases in animals and humans.In December 2019, several pneumonia cases with an unidentified etiology were reported in Wuhan, China.A novel coronavirus was identified on 6 January 2020 as the cause of these cases andnamed Coronavirus Disease 2019 [COVID-19]. On 11March 2020, WHO declared the novel coronavirus as anoutbreak. Several studies reported auditory symptoms and affection of hearing assessment tests as PTA and OAEs.
Objective:To assess hearing in recovered SARS-COV-2 patients using PTA, TEOAEs and ETF. Also, to correlate between the complaint of the patient, the disease severity and hearing affection.
Methods:A case control study, each of cases and controls group comprised 58 subjects age and sex matched with age ranged between 18 to 50 years. Hearing was assessed in both groups using extended PTA,TEOAEs, immittancemetry and ETF test.
Results: PTA showed a statistical significant difference between cases and controls in right ear thresholds at 250 Hz, 500 Hz, 4 KHZ, and 8 KHz and in left ear thresholds at 250 Hz, 4 KHZ, 8 KHz and 12.5 KHz. Also, a statistical significant difference was found between cases and controls regarding TEOAEs overall reproducibility and amplitude (SNR). There is a relation between patient’s complaint of hearing loss and PTA affection and between patient’s complaint of tinnitus and OAE affection. Furthermore, there is a relation between patient’s complaint of fullness and ETF affection. Correlation between PTA thresholds affection and COVID 19 disease severity showed a statistical significant difference in both ears.
Conclusions:COVID 19 has unfavorable effect on hearing either in symptomatic or asymptomatic patients.
