Abstract:
Background : Since loss of taste and smell is the most obvious symptoms of COVID - 19 infection , this indicates that SARS CoV - 2 affects sensory neurons . As a result , it is thought that the virus itself would harm other senses , such as hearing . Unlike taste and smell , which do not require measuring instruments because they are very clear indicators , the assessment of auditory status initially requires knowledge of hearing thresholds ( sound intensity ) in the audible speech frequencies ranges , which is the pure audiometry ( PTA ) handles . Keywords : Covid - 19 , Hearing loss , sensorineural hearing loss , Sound , Hearing . Objective : Evaluate the hearing threshold shift in patients infected with COVID - 19.Identify the frequency , epidemiology , and severity of sensorineural hearing loss among those patients in comparison to non infected patients . Methods and patients : The study included 50 patients infected with COVID - 19 ( ages 19-45 years ) , 21 males and 29 females , with a mean age of 31.7 ± 7.8 years and 50 patients ( ages 16 to 45 years ) 19 males and 31 females . With a mean age of 32.1 ± 9.1 , they were referred to the ENT clinic / Yarmouk Teaching Hospital / Baghdad from May 2022 until August 2022 . All participants were informed of the purpose of the study and potential benefits before agreeing to participate . All participants were examined by otoscope and tympanometry to ensure there was no excess wax , which causes hearing impairment and to check for problems in the middle ear , ear canal and eardrum and then a PTA test was performed Results : The results of this study included patient characteristics , the results of pure audiometry ( PTA ) in decibels between the left ear and the right ear of patients with the emerging corona virus , and the control group . There is no significant difference in age between the covid 19 group and the control group . We found 15 patients in the covid 19 group with sudden sensorineural hearing loss , while in the control group we found 26 patients with sudden sensorineural hearing loss . There is a significant difference between sudden hearing loss in covid 19 and the control group . Conclusions : It was discovered in this case - control study that there is a gradual elevation of hearing thresholds above normal range towards the higher frequencies especially 2000 , 4000 , 8000 Hz in both ears , and severity of hearing loss was most in 25-40dB ( Mild severity ) . It can be said that there is mild effect of COVID - 19 on hearing efficiency compared with control group .
