Acute Profound Sensorineural Hearing Loss After COVID-19 Pneumonia

Sudden irreversible hearing loss post COVID-19

“…Another two cases were described where new onset sensorineural hearing loss in SARS-CoV-2 positive patients with no previous otological problems was seen and no other causality found. 7 8 Degen et al 7 reported a previously well 60-year-old man with severe COVID-19 requiring ITU stay who developed right-sided deafness and left sensorineural hearing loss and received intratympanic steroids and a cochlear implant. Rhman et al 8 reported an otherwise asymptomatic patient who presented to the clinic with sensorineural hearing loss and a SARS-CoV-2 positive swab and received intratympanic steroids which resulted in some improvement.…”

Coronavirus disease 2019 and sudden sensorineural hearing loss

“…4 There are only three other case reports to our knowledge that have reported sudden SNHL in Covid-19 positive patients. [3][4][5] Immune-mediated inflammation likely plays a significant role given that severe cases of Covid-19 have been associated with dysregulation of the immune system. In these severe cases, an increased neutrophil-to-lymphocyte ratio and elevated inflammatory cytokines such as interleukin 6 have been observed.…”

“…In these severe cases, an increased neutrophil-to-lymphocyte ratio and elevated inflammatory cytokines such as interleukin 6 have been observed. 5 In addition, Covid-19 has been shown to have deleterious effects on cochlear hair cells, with reduced amplitude of transient-evoked otoacoustic emissions in a group of 20 coronavirus positive asymptomatic patients. 6 Corticosteroids are widely used in the treatment of sudden SNHL; however, steroids are controversial in the setting of Covid-19.…”

Hearing Loss in SARS-CoV-2: What Do We Know?

“…A total of 7 articles were obtained, of which 3 cross-sectional study and 4 case reports ( Table 1 ). 2 , 9 - 14 A total of 35 patients with age ranging from 20 to 60 years were included. All patients included had hearing loss as a primary symptom and the accompanying symptoms were tinnitus, vertigo, and otalgia.…”
