Sudden sensorineural hearing loss after COVID-19 vaccination

Area of Science:

• Otolaryngology
• Vaccinology
• Neurology

Background:

• The rapid spread of Coronavirus disease 2019 (COVID-19) necessitated widespread vaccination efforts globally.
• While COVID-19 vaccines are crucial, rare serious adverse events like Guillain-Barré syndrome, thrombosis with thrombocytopenia syndrome, and myocarditis have been documented.
• Otolaryngologic adverse events, including sudden sensorineural hearing loss (SSNHL), have been anecdotally reported following COVID-19 vaccination.

Observation:

• This report details three patients who developed sudden sensorineural hearing loss (SSNHL) within three days of receiving a COVID-19 vaccine.
• The temporal proximity of SSNHL onset to vaccination prompted an investigation into a potential association.

Findings:

• The study observed three cases of sudden sensorineural hearing loss (SSNHL) occurring shortly after COVID-19 vaccination.
• While a definitive causal link between COVID-19 vaccination and SSNHL is not established, the occurrence warrants attention.

Implications:

• The potential for sudden sensorineural hearing loss (SSNHL) as an adverse event following COVID-19 vaccination should be recognized by healthcare providers.
• Given that viral infections can cause SSNHL, and vaccination is a medical intervention, this otologic emergency requires prompt steroid treatment.
• Further research is needed to elucidate any potential association between COVID-19 vaccines and SSNHL.
