 Currently, there are few studies on the relationship between COVID-19 and the auditory system. In the current study, a review of the studies conducted in the fields of etiopathology, clinical manifestations, research, and treatment of hearing loss caused byCOVID-19 was conducted, which can be used as a baseline for future studies.

 We utilized the research approach suggested by Arksey and O’Malley to carry out this scoping review. Search was conducted in Farsi and English with a focus on the onset of hearing loss in patients with COVID-19 through Medline and PubMed, and Google Scholar search engine. Studies included were those involving adult patients diagnosed with COVID-19 who experienced hearing loss, ear pain, ear discharge, and otitis media. Studies were eligible for inclusion if there was a description of the otologic dysfunction, specifically onset, duration, or clinical outcomes.

 Among 90 studies identified, 35 studies were included in the review process. Our findings suggest several possible mechanisms for sudden sensorineural hearing loss (SSNHL) in COVID-19 patients, and COVID-19 infection could have deleterious effects on the inner ear, specifically on the hair cells of the cochlea despite patients being asymptomatic and early identification of SSNHL in COVID-19patients can save the hearing and also patient.

 Hearing loss in COVID-19 infection has not received much attention by health care professionals. Sensorineural hearing loss (SNHL), tinnitus, and/or vertigo have been shown to occur during and following COVID-19 infection. Due to lack of research studies, and the inconsistency and even contradictory of the findings, it remains questionable whether COVID-19 contributes to the high incidence of hearing loss. The proper understanding of the mechanisms behind hearing loss in COVID-19 infections needs further research. However, it seems likely that SNHL could be included among the manifestations of those-called “long COVID” syndrome.

Superior semicircular canal dehiscence (SSCD) is a rare bone defect in the petrous part of the temporal bone. In this syndrome, a third window is created between the middle cranial fossa and the bony labyrinth of the inner ear which can lead to stimulation of the vestibular system by sound. Patients usually have symptoms such as vertigo, imbalance, autophony, pulsatile tinnitus, and aural fullness. The clinical symptoms of this disease vary from person to person.

The Case: 

This study reports a case of a rare bilateral SSCD in a 39-year-old woman with imbalance and autophony problems. The audiological findings showed a bilateral mild conductive hearing loss at low frequencies with symptoms of vertigo and torsional nystagmus. The SSCD was diagnosed by computed tomography. Then, the patient underwent bone repair surgery. Auditory and balance tests were performed again after the surgery to evaluate the extent of recovery.

The SSCD can be diagnosed by using the mentioned test battery. By choosing the appropriate treatment methods and following up of the outcomes, most of the problems of patients with SSCD can be solved.

In the middle ear inflammation, otitis media with effusion (OME) leads to a sterile effusion. Although most OME resolves without any complications, long-lasting OME may cause conductive hearing loss (CHL).

In this article, we investigate the validity of the Rinne and Weber tests in different frequencies of tuning forks in predicting the conductive hearing loss secondary to OME as diagnosed by more modern audiometric tests.

A case series of 25 consecutive patients visited the Loqman Hakim Hospital clinic. Each patient was evaluated by tuning fork tests (256, 512, 1024, 2048 Hz), audiometry, tympanometry, and tympanocentesis.

In evaluation of the hearing status in OME patients, there was no significant association between the Webertest, audiometry, and tympanometry. The 256 Hz Rinne test correlated with the level of hearing loss in patients with OME. Results revealed no relationship between the presence of glue ear, audiometric, tympanometric, and tuning fork tests.

256 Hz Rinne test can predict the presence of CHL in cases suffering from OME. Adhesive otitis does not worsen thehearing condition of patients.

Otosclerosis is a primary disease of the temporal bone and oticcapsule with autosomal dominant transmission and variable expression. The exact pathogenesisand factors affecting tinnitus in otosclerosis patients are unknown. This study aims to find the effect of stapes surgery on improving tinnitus in otosclerosispatients.

This study aims to find the effect of stapes surgery on improving tinnitus in otosclerosis patients.

Twenty-nine otosclerosis patients with preoperative tinnitus were enrolled in the study. Patients were divided into three groups; patients with high pitch tinnitus (>2 kHz), patients with medium pitch frequency (500-2000 Hz), and patients with low pitch frequency (<500 Hz). In addition, a visual analog scale was used to evaluate tinnitus severity.

In our study, 15 (51%) patients' tinnitus showed significant improvement, 5 (17%) patients' tinnitus converted to medium and low frequency, and nine (31%) patients' tinnitus remained unchanged. The majority of subjects (24, 83%) have decreased VAS scores (p= 0.001), and 5 (17%) patients remained unchanged. Results of pre and postoperative ABG showed that 82.3% of subjects (n=27) have postoperative ABG<10, and 18% (n=6) have ABG of 10 to 20. The patient's mean ABG was decreased from 35.9 ± 10.7 dB before surgery to 9.03 ± 7.9 dB after surgery (p= 0.001).

Patients high pitched tinnitus may be a better candidate for stapes surgery, although others can also benefit from surgical intervention.

In December 2019, the first Coronavirus disease 2019 (Covid-19) case was observed in Wuhan, China, and afterward, the world has been exposed to an ongoing pandemic. The Covid-19 has different symptoms, such as fever, coughing, shortness of breath, muscular pain, headache, diarrhea, nose running, and a sore throat. However, the symptoms of Covid-19 are not limited to these ones.

The present study reports a 39-year-old female patient complaining of earache and hearing loss with no other Covid-19 symptoms. The medical tests and diagnoses finally inferred that she was suffering from the Covid-19.

In addition to the common symptoms of Covid 19, acute otitis media can be considered as another symptom of this disease.
