Summary
Sudden bilateral deafness occurred in a patient with severe COVID-19. This hearing loss, likely a complication of SARS-CoV-2 infection, required cochlear implants and a hearing aid.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Virology
Background:
- Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, leading to coronavirus disease 2019 (COVID-19), can cause a range of systemic complications.
- The neurological and systemic effects of SARS-CoV-2 are still being investigated, with emerging evidence suggesting potential impacts on auditory function.
Observation:
- A patient experiencing severe COVID-19 developed sudden bilateral deafness after intensive care unit treatment for acute respiratory distress syndrome and acute kidney failure.
- Pre-infection hearing was subjectively normal, but post-infection audiological assessments revealed profound hearing loss in the right ear and deafness in the left ear.
Findings:
- The patient underwent treatment with cochlear implants for the left ear and a hearing aid for the right ear to address the profound hearing deficits.
- The sudden onset of bilateral deafness is strongly suspected to be a direct or indirect complication of the SARS-CoV-2 infection.
Implications:
- This case highlights a potential, severe auditory complication of COVID-19, emphasizing the need for audiological monitoring in affected patients.
- Further research is warranted to elucidate the mechanisms by which SARS-CoV-2 may cause sensorineural hearing loss and to inform clinical management strategies.

Hearing

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Tracheostomy Decannulation
554
Tracheostomy decannulation is a significant milestone in the liberation of mechanically ventilated patients. Despite its importance, there is no universally accepted protocol for this procedure. This demands an evidence-based, individualized approach.
Description of the Procedure
Decannulation refers to the permanent removal of the tracheostomy tube, signaling the resolution of the condition that initially necessitated the tracheostomy. The process requires a well-coordinated interplay between...

Chronic Pharyngitis
7.6K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
